With these larger screens and powerful processors, I can't say I'm totally surprised at the lower battery life compared to all the iPhones. They have smaller screens and the O/S is more tightly controlled and optimized for the hardware to maximize battery life.
With that said, I must admit, I'm somewhat disappointed with the battery life on this S3. I've now had it for two weeks so after lots of tweaking, rooting, apps installs and configs, battery and task monitoring, etc, I've kind of settled into my normal usage pattern which is typically pretty easy on the phone as more than 50% of the time I'm working from my home office with the phone plugged into USB so it is rare I have to leave in the morning and go the whole day without having to eventually sit back down at my computer and plug the phone back in.
However on the weekends, with kids sports and such, I'm now seeing the limitations on battery life on this phone. I have it set to:
Auto Display Brightness
No updating of apps unless on WiFi
GPS and Wifi turned off when I leave the houose (automatically via Llama - I turn them on only when I need them)
Power Saver Mode, all options except CPU power saving checked. (Kind of bought the phone for fast CPU although I'm not a gamer - just a multitasker and web browser)
Auto Screen Tone Turned On
Most other specific apps that have option to not download data except wifi I have that option turned on (aside from Taptu news feeds - 2 hour updates and Alerts from ESPN ScoreCenter - get maybe a couple alerts every few hours)
Haptic feedback turned off
Here's where I was shocked. First time I did some serious browsing was in a movie theater where I got there early and had about 20 min to burn so I did constant web browsing over the LTE connection. Watched batter plummet about 15% in 15 min. Whoa!
So is this just "how it is" with this phone that heavy LTE data usage eats battery like no tomorrow?
Other thing I noticed, is Using GSam, I see a task usually being in the top 3 or 4 most of the time with around 15-20% of the App Battery Usage total. It's called "System (*wakelock*)" and when I look at properties it shows around 6-8 wakelocks and Included Packages is just one "PowerAMP Full Version Unlocker" Included Processes: *wakelock* and com.maxmpx.audioplayer. But this is when I'm not using PowerAMP. In fact it happens after phone has been rebooted and I have never launched PowerAMP once!
I did notice something similar on the HTC One X+ I tried then exchanged for the S3 where I found a task associated with beats audio was eating up CPU/Battery when no music app was open as if it was periodically scanning my large MP3 library of 2,600 songs. Maybe PowerAmp is doing something similar?
I've found I'm not the only one noticing this:
http://forum.powerampapp.com/index.php?/topic/2662-battery-drain/
Well, first off, i think the main reason why the iPhone gets better battery life isn't because of the smaller screen or iOS being "optimized for the hardware". It's probably more due to the fact that it doesn't really run much of anything in the background. Very few apps actually continue to run when you leave them. It's kind of a pseudo-multitasking environment.
As for the S3's battery life.... it could be PowerAmp causing it. I also don't see why you'd want to keep power saving on the CPU off. It doesn't really seem to have that much of an impact on performance that i've seen while generally using the phone for web browsing and such. And no matter what phone you're on, LTE will kill the battery in no time flat.
I think you should give some time to settle your battery first...even after flashing a new rom its take couple of days for the battery to settle down. The first day i used my phone, the battery doed in 4 hours...now after 4 months it lasts for 15-16 hrs of normal to heavy use.
LTE does eat lots of battery, whenever i go in LTE area i have to switch my data off to keep my phone alive. That's why people like to have the ability to switch between LTE and HSPA+. Search to find that mod.
You can never compare iPhone with S3. As the above poster said, there is no multitasking in iPhones. The screen is small and not as good as S3. SAMLOED screen takes lots of battery.

I totally agree with you. You have to give it time to settle in. You can also run a battery calibration to try and help as well. I have LTE here in Omaha and I usually get at least 15 hours before I need to charge my battery. I have a QCell battery and it works awesome.
I will live with the battery life so I can actually see the screen without having to squint my eyes. I used to have an iPhone as well but that was years ago now and Android will always be the best.
Don't get me wrong, as a "Power User" coming from the iOS Jailbreak world, hardware and customization-wise, I love this phone a lot more than I like my iPhone - but mostly it's the big screen that I'm enjoying. Have had a couple crashes in the first two weeks which never happened in iOS but no biggie.
So I suspect its primarily the LTE, but combined with large screen, true multitasking O/S, etc, obviously battery life is a challenge. I would slightly criticize Samsung for maybe being a little too obsessed with keeping the phone thin. I know you can buy the bigger batteries with a replacement cover but that looks like it really adds major thickness to phone. They should have went for a 2500-2700 mah battery and increased the thickness slightly IMHO.
But hey, at least the battery is removable. So I can spend little money and get a QCell, charge it and keep it in my car or on my desk and if I know I'm not going to be able to charge the phone all day, just pop the extra battery in my jacket pocket.
The LTE usage is a bit of a mystery to me. You would figure, with LTE, you can download files faster so you spend less time actually using the phone. But obviously it appears the energy consumption is trumping the increased efficiency in data transfer! Too bad.
Why the battery 'breaks in' over time is even more of a mystery. This latest battery technology should not have any sort of break-in or memory issues. But I'm no battery expert. But my gut says there's something else at play. I've seen many threads over past couple of years that discuss an issue relating to Android doing some sort of "media scan" after boot and/or periodically. Maybe the battery break-in is more about the databases the O/S is creating and updating in the background "settling down" more than anything to do with the characteristics of the physical battery changing?
One thing is for certain though, battery life IS a common issue for most higher-end Android smartphone users. Not a deal breaker in the least for me, but will be interesting to see how the phone "seasons" over time regarding battery. I used Titanium Backup to freeze Power Amp and downloaded N7 instead just to rule Power Amp out. I just took a 1.5 hour shopping trip. Didn't use LTE data. But spent about 45 minutes at the grocery store using their wifi to access all my coupons and shopping lists. Battery was 97% when I left house, 77% when I got home. Ouch. Well, that was probably more like a 2 hour round trip. Still 20% in 2 hours is not good especially considering I had 0 talk time and wasn't using LTE data.
The crazy thing is, Gsam says 12% screen, 86% apps. Under apps it says 23.6% Kernel, 19.3% Media, 19.3% N7 Player!!! And I didn't play any music!!!! This is leading me more and more to believe this all has something to do with having an extremely large music collection (2600 songs) on the phone and the phone is building a database and it just takes time. Pure guess.
Get his app disable autostart of the applications that are not needed. Also, get betterbatterystats to get a more detailed idea of whats going on with your phone.
how bad is your battery life? fwiw my wife's iPhone 5 gets horrendous battery life. makes the s3 look like a miser.
16 - 20 hours would be reasonable IMHO, or a average drain of 4-5% per hour. assuming you're actually using the thing... I never understood people who cripple the thing and never touch it in order to get max life.

You know when someone pushes away an iPhone groupy I'm pretty sympathetic but this post is just a noob rage idiotic post. I didn't even read through all your points but will just say you need to spend more time learning
-there is autobrightness on root (and non rooted) and in fact autobrightness doesn't necessarily save battery...as much utiltiy as having say a brightness notification in the app bar or something like lux that allows you to control brigntness by environment/app etc
-it says nothing of what you have running in the background, spam apps, wakelocks etc (bbs) The fact your apps and music is taking up more battery than say cell tower stanbdy and screen display is an obvious red flag
- says nothing of how you checked your connections and how reception is in your area
Another point is the iphone 4 and 5 are MUCH thicker than the galaxy s3...they hold relative to the backgroudn processes etc running, a much larger and thicker battery. The same physical thickness of the s3 battery you could buy a battery with nearly twice as much juice.
We dont' know how you optimized your phone for your uses or whether you cleaned up processes, apps etc, how cleanly you flashed. Go and learn then come back and cry

Well here's an update. As I mentioned, I froze PowerAmp and installed N7 instead. I could have swore I reset the GSAM battery monitor, AFTER N7 scanned all my media files. Yet once again, like PowerAmp (via System *wakelock*) N7 was third highest battery eater over 2 hours of "normal" usage WITHOUT LTE Data Use, only Wifi and NO TALK TIME and WITHOUT USING N7!
So I dumped N7 and installed Player Pro. Just went out again for 2 hours to my son's basketball practice. Spent the 1.5 hour practice reading e-mail and doing some web surfing ALL ON LTE! Battery went down like no more than 10% !! At the beginning of the practice I played a song in Player Pro for a few seconds then backed out of the app. Checked GSAM 2 hours later, no significant PlayerPro battery usage!
It is more and more looking like something is going on with PowerAmp and N7 regarding cataloging of large music collections. So I'll stick with Player Pro and see how things go over the next few days.
Thanks to those with the constructive criticism. This has been one of the pluses of moving to Android. There's a lot larger population of "Power Users" than on iPhone that are willing to help someone relatively new to the platform.
yea... that's the one thing i had a feeling it might have been doing, but wasn't exactly sure as i've never really been that media-crazy with my phones. Good to see that you found the issue, though.

Yeah, "battery break-in" is a bit of a misnomer. What's actually happening is that the stats the OS keeps on the battery capacity and usage are being rebuilt. It takes a few charge cycles for your system to "learn" what it needs to accurately show you remaining capacity, etc.

Good move! I use PlayerPro and I love it. It's one of my few "must haves", not least of which is its ability to sync ratings back to iTunes with iSyncr. None of the other major players have this. This is important for me as I'm also an iOS refugee and I still have all my music in iTunes.

power user here too coming from iphone 3g, 3gs, 4 to samsung skyrocket, note, nexus to the current at&t sgs3. all have been jailbroken and rooted for "customization" purposes and the first thing i noticed going to the android phones was how poor the battery life was when compared to any iOS device; even when the devices were stock. I can deal with it because of how much customization i can do with android that i can't do on iOS so for that reason alone i stick with android. and also nothing apple has done has impressed me with their iPhone series yet. might pick up an iPad mini retina one day :laugh:
anyways, back to your battery issue. have you tried going to stock rom or formatting just to make sure its not a hardware issue? i know for mine, one time my data partition that had my music had some corrupt file that had the media scanner always running and killing my battery. i had tried everything and there was no way that in 8 hrs i'd have < 30% left with no usage. i finally deleted and formatted everything, went to pure stock with no files except for my contacts and no email sync. then i got 15 to 20 hours... that's usual for the sgs3, a tad less than my old iphone 4. that told me my battery wasn't bad.
i ended up keeping an eye on wakelocks and re-installing all my apps and putting all my music back on and my battery issue dissapeared and i'm happy. still have poweramp installed, but moved to using google music for cloud and local music. what made me really happy was going to a hyperion battery and the slimmer extended sedio case for 2 to 3 days of battery life on this sucker for a decent price. :good: still have the stock batter for backup too!
I'm not on a Custom ROM. Just rooted.
I installed Better Battery Stats to see how it worked. Don't like it as much as GSAM. Seems you can get a bit lower-level process info upfront, but the graphing is barely readable and it doesn't show percent usage of battery for each process. Just number of s(econds) and blue and red line? Maybe I'm missing a setting? I think BBS may be popular as maybe it existed before GSAM (formerly Badass Battery Monitor I think) or maybe there is just something about BBS that I haven't realized yet is a major advantage over GSAM? They both do the job. Sorry for going off on a tangent.
The process hogging the battery the most now is Google Maps and I know from searching and reading this is VERY common. It can be related to ANY app wanting to poll your location. I'm not yet sure though if the usage is excessive. Looks like not. I turned off all of the Location settings in Maps (but left "Location and Google search" in main Location Setting ON as I read that really defeats a lot of functionality. Google Now wasn't happy I turned of Location History (in Maps) but I still get the current commute times and local weather on my Google Now so I have yet to discover any big disadvantage of turning off most (not all) of the Location settings in Maps if you don't want to share your location or see your location history.
Apparently Google Now and potentially other apps like Facebook, etc. want to use Google Maps to poll where you are. One user said turning off History helped on the battery - makes sense as now Google Now isn't constantly trying to see where you are even if the phone is just sitting on your nightstand! I hate that big brother feeling so anytime an app has an option to turn location awareness off, I usually use it. When I go to use Maps I just turn the GPS on. But I still need to learn what I'm missing out on, when turning off some of these settings. Now I'd like to figure out how to get GPS to turn on automatically any time Maps is manually launched and then turned off automatically anytime maps is closed! That would be nice. Surprised that function isn't built-in to Android as opposed to just prompting you to take you to settings. Guess I may have to break down and learn how to code in Tasker instead of using Llama for my automation needs.
I've left the phone unplugged for what, 8 hours now. Very light usage today. I'm at 80%. BBS is showing 3.5%/hour. That's 28 hours. But like I said, no talk time on the phone today, a half dozen texts, no web browsing and maybe 30 min of total app usage so I would expect 3.5%/hour.
Bottom line is it looks like I don't have any major issues like I had on the stupid HTC One X+ that was getting hot. Seems like the media player switch is what did the trick. I'm just curious why apps as popular as N7 and PowerAmp would be any different. It could have been just timing in that I switch to Pro Player about the time the O/S was done doing it cataloging of the media or whatever it does. I'm sure 2,600 high bitrate songs (14GB) of songs on the sdcard is pretty above average for your typical Android User. Wish there was more in-depth technical documentation on some of these processes though published by Google for us Power Users to read if so desired. Guess that's why we have XDA Forum.
-- add --
Duh, just saw the first condition in Llama is "Active Application" the problem is, I only want the GPS to turn on when I manually launch the app myself. I hope an app trying to use Maps in the background doesn't trigger the GPS on. Guess I'll find out.
-- add --
I forgot why this isn't possible. Google doesn't want to allow ANY apps to turn GPS on/off automatically due to privacy issues. Is there a setting to let the user decide this? Make me feel like they're treating me like an idiot!

I have charged it in the morning until it was full, and started playing with it.
It was on for 9 hours until the battery was completely dead.
I used it since 11:30 until 3:30pm, then I left it on standby for a 2 hours (battery was at 14%). I came back used it for another 2 hours, and it went dead.
Everything was on except for bluetooth and GPS.
Android Operating system used 83% of the battery and all the other application were under 5%.
I did quite a bit of browsing, photos, movies, youtube, downloaded some apps, etc...
What do you all think about the battery performance?
At the moment it is charging and I will leave it plugged in until the morning. It is also turned off.
What are your experiences? Opinions?
9 hours only? That's not good ... But probably you have quite some widgets that actively sync etc. etc.
i wouldnt worry to much as you probably just received it and you must have played with it for a while, and also try turning off the auto update of facebook, email etc etc
thats kindda dispointing, ... even with updating i expected it to last at least one full day, I mean when they put many widgets they should take into consideration the battery life ... hope its cuz the battery is new, and needs some few charges to feel maximum capability
As I said, I did have everything on apart from GPS and Bluetooth. (including updates).
And yes I did use it for 6 full hours (medium screen brightness).
Downloaded apps, watched videoclips, played some flash games, wrote e-mails, wrote texts, browsed the internet, etc... funnily enough I EVEN made 1 (one) phone call!
I wouldn't worry about it though. ALL my phones only lasted for about 8-10 hours the first day when I got them.
Doesn't new Lithium-ion battery needs a couple of charging cycles before
reaching optimal capacity!?
Would be nice if someone could update us in this thread about the battery life when you've had it a few days and it's being abused less
We must however point out a couple of things regarding the Desires out there at the moment, although we certainly do not wish to discredit anyone else's reviews.
We have been informed by a reliable source that some HTC Desires have been out for review for several days now, but these devices did not come from the same source as ours. These early versions did not contain the final ROM that we have been waiting for and I am reliably informed that those devices will have essential features missing. They have also had problems with the OS crashing and serious battery issues which is clearly down to the fact that Google had not completed the ROMS when the devices were shipped.

Let's wait ~7th April and then we will see true battery life...
I'm fairly sure that 9 hours of constant use is pretty damn good for any device. If I use my Touch HD for browsing the net/listening to music/ syncing etc it will die in far less than that.
Remember that it is a miracle that the iPad lasts for 10 hours of constant use, and thats got a massive battery in it!
So yea get used to it! At least while you are playing with it being a new toy and all.

dont forget that the iPad has 9.7-inch (diagonal) LED display, so that shouldnt be a reason, and dont forget that the Desire's display is AMOLED which should be a battery life saver.
For the OP, if you could try using it the same (constantly) but disable the live wallpaper

Agree with the AMOLED, but it's running a 1ghz processor along with the already perceived power hungry android.... Gotta admit that if you expect it to last more than a few hours of playing with, will be sorely dissapointed.

It's not the same thing. "LED" is a backlit LCD-display, AMOLED is an active matrix OLED-display, completely different technologies.
TFT-LCD's use a backlight, OLED's has active pixels that light up per pixel and does not need an extra backlight.
The battery life is really poor.
I went to bed last night with it fully charged and this morning it was completely dead. Albeit I left meebo running in the background along with lookout and advanced task killer.
Nothing was set to update as I've deleted the friend stream and rss feed.
I'm pretty sure this phone should last a lot longer than 9 hours on standby.
If you have read the whole thread, you'll see that there might be an issue with the pre-released models. Unlocked/retail phones coming out next month with latest software will probably not have this issue.

I think someone should actually test turning everything off except gsm. No data connections, no updating of anything. No GPS, bluetooth, sync, no applications running. See how much it goes down overnight with everything off.
That could maybe be a good idea, just to see how much it goes down. But if you can't use the phone at all, I just can't see the point of having t his phone. It's made to be used and you are supposed to be connected at all times, so if HTC has made this phone with so bad battery performance, that just basically sucks.
On the other hand, it seems that the final ROM from HTC was just confirmed at Google this friday, so im guessing these early phones out there does not have the final ROM.

My Nokia E75, i run wifi all day, with push mail, and Zozoc (WiFi/GPRS Messaging client) and i can easily go through one whole day (and few hours). the screen is TFT, non-touch, and small.
I know that we cant compare cuz they are entirely different, but the point is, the battery life should not be (and i hope it is not) that bad, even when running apps in the background. one day (or few hours below that) should be decent.

The OS in the T-Mobile versions have already been approved by google, so its not a pre-release.
and i agree, someone should try to stop live wallpaper and updates (just use it as simple phone, calls, messages and a little bit of WiFi) and see how much that goes
I quote the following from the first detailed review from techradar
The battery in the HTC Desire was 'only' a 1400mAh effort - we'd have like to see a 1500mAh option there, as is the case with so many other smartphones at the moment.
We're also a little concerned about the battery life - it dropped rather quickly, and although you'll get a day's worth of use out of it under normal use (ie web browsing, calling etc) it can drop a little alarmingly fast at times.
We had a little look at what was munching on the power so much (thanks to the Android battery meter) and it seems to be the widgets (in particular FriendStream) and synchronising that's taking a lot of the power, along with the constant flicking to roaming networks and back to 3G.
We found a big increase in battery life if we stopped updating Peep, Friendstream and emails all day long, and when set to '2G networks only' the battery life also improved to three days' use without problem.
Click to expand...
Click to collapse
this seems good, this is decent! i dont use 3G much, i would probably update the friends stream on demand, and with a little bit above average use, i should get 1.5-2 days without problems (based on the review)
No I want some people who already have the desire to try this and come back with the result
Today was my first day at work since i got my Desire on Sat. So it was the day without regular charging.
Firstly, reception was poor as compared to what i was getting with Touch Pro 2. Same network (Orange), same place, less signal bars and less 3G coverage.
Secondly, unplugged phone 7 o'clock this morning, 100% charged. All day only had time for couple of calls (10-15mins). Used internet (3G when available) for max 20-30mins. Tried couple of games for 15-20 mins and at 7 o'clock at night, the battery was 15%. This is not a heavy use by my standards. Used to do a lot more on Touch Pro2 and battery used to last 2-3days. (I know the capaciy difference btw Desire and TP2 battery but still, Desire should last atleat > 24hours)
Not sure if all these issues are related to Orange ROM/Radio. Will we (on Orange) get OTA firmware update like T-mobile, which has apparently improved their battery life? If not then ...... :-(. Not satisfied with the battery life. Shame it is such a good phone but battery life and signal strength is putting me off.
Whats the fun if you have a "superphone" in your pocket but cannot use it to its full potential due to these two isuues.
Mine was the same,
But after a weeks worth of usage, its now reasonable, IE 18 hours between charges,

I totally agree, there are other posts telling us to turn off or reduce all sorts of settings, its ridiculous that you would have to run any phone at less than its full potential just to compensate for a poor battery.
Sure you could buy a second battery but if that was necessary then they should put two in the box
If you leave gps on then you are asking for trouble, a lesser extent wifi. Having a toggle on off isn't such a hardship though. Poor signal hammers the battery too.
I easily last the working day (7-7) with an hour of music and 2 hours surfing and a smattering of calls and texts.

Come on guys, if you have a laptop, and you turn on bluetooth, wi-fi, play some games etc, it WILL run the battery down faster. It's just common sense. Just because this phone does heaps of things, dosn't mean it will last forever. As phones get more features, they are getting worse battery life - in general. And android is a data centric device, I would get used to it, or simply turn off some synching features if you need to get through more than half a day. Or perhaps get a spare battery etc.
Just out of curiosity did you have your previous phone to constantly sync throughout the day for time, email, google account, marketplace updates, location, weather using gps, 3g, hsdpa, accelerometer etc? Remember some of these connect are activated every 5 mins or so. Will make it worse if you have poor reception. COMMON SENSE PPL!
My issue is that even after the T-Mobile update, last night I charged phone on this time and it would only get to 98% again. Then drop down quickly.
If I charge it off, It seems to be ok (although I will test this again.)
Frustrating.
My battery life is woeful (TMo uk, updated firmware). I've been trying to figure it out using Juice Plotter to record power usage. Basically, whatever I'm doing, if it's on the battery falls off a cliff - I'd say 10% per 30m and my first impression is that it makes little difference whether networking is enabled or not. This makes little sense to me, I've always found in the past that 3G is just about the most power intensive activity on the smartphone, but it's consistent with some experiences I had flashing roms on my Blackstone - some of them would just run the battery down, others would go for ages. One hypothesis is that when a phone is in that kind of "sick" power state, the drain is not really related to which facilities you're using, but something deeper - perhaps the CPU is running full throttle all the time, or something else. I have no idea what's going on right now but I know I have an unusable phone which lasts half the time my Blackstone did with heavier use. I think many others have the same problem and I wonder if there's a bad batch. Bad news if so as we'd have trouble proving it and getting exchanges.
My next step I think will be to hard reset and run it in a very basic mode for a while, maybe some of the apps are causing it.
I'm also finding out that battery life improves dramatically after the 5th 6th charge. When I first got my Desire I could barely make it through the day, after properly charging and letting it discharge all the way to 10-15% now I get 18-20h of battery life with wi-fi on non stop (but with the setting to to turn itself off after 15mins of inactivity).
I was very worried about this when I first got the phone, but now it's starting to be better and better at battery life. I know my demands from a smartphone when I buy it and if a phone get's me through the day I'm OK with that, plus I have chargers at home, in my car, at work, so it's not a problem
I've got one of the very first batch of T-mobile Desires that were shipped on 26th March. It has been updated with the T-mobile 1.15.110.11 patch.
I last charged it on Saturday afternoon. I've only had to start charging it again this morning Tuesday. I've been making a few calls, probably 10-15 minutes total. A few texts. Browsing with G and 3G, maybe a few of hours worth in total. Little bit of Bluetoothing, though that's only a couple of minutes worth. I've had it down the pub a few hours where the T-mobile signal isn't brilliant, so it will have been doing a little "shouting" to find and communicate with the nearest T-mobile mast.
But that means it's lasted a good 66 hours admittedly with fairly moderate use. GPS, Wifi and Bluetooth are turned off unless needed. And it's not regularly Syncing with Facebook, Twitter and all that stuff. The only regular syncing is the weather.
Not sure if these are bugs with some hardware/software or standard functionality with your usages. I'm getting excellent battery life with my usage patterns/settings and far happier with this than with any of my previous devices, since this adds an exorbitant amount of power-draining functionality and flexibility over them too.
- Heaviest use is netting 28-33 hours.
- Typical use is getting minimum 3-3.5 days.
- Light use (also the norm for me me) lasted 5.5-6 days.
- Basic inconsistent call/message/email/net/stocks/news/stop watch/GPS/ compass/notepad/office/weather/ vid/pic/audio throughout the day kept the battery at 84% after 24 hours. 3G off, using WiFi. I don't keep any but the needy apps/settings running BTW.
- Charges to 100% always and stays up there consistently as expected.
However there is a pertinent aspect yet unmentioned;
Biggest difference between my usage and the typical internet crowd is that I don't use or bother with "social networking" (Facebook, MySpace, Twitter, etc) or its likes nor do I play any games on this (hence sync with such apps is off and any updates are set to manual). However rss feeds, e-mail and IMs with close ones I do use during the day when I have spare minutes.

Same situation as mine there.
Sent from my HTC Desire using the XDA mobile application powered by Tapatalk
I'm deffo leaning now that there are faulty batteries out there causing the problem. I can get good life if I can get the battery to charge properly. but when it doesn't battery lasts hardly half a day. I don't use any apps that require automatic updates (all manual or off). But net on drains it very quickly (if I leave data on). Faulty Batteries I feel.
My Desire has a better ability to hang on to a weak signal than my other phones. I am on T-mobile. Battery life is adeqaute, in that, I can get through a day of use before a charge is needed. Will switch-off GPS and see what happens -I never had GPS on all the time on my other Smartphones.
Coming from a G1 that could barely make it through the day on standby this phone seems pretty good.
I got mine last friday it has just come off of it's third charge. I charged it for 3 hours when I got it, ran it right down >10% then left to charge up fully again.
I installed JuiceDefender and bought the UltimateJuice upgrade as soon as I got the phone.
Day 2 (with JuiceDefender) - battery lasted 13h27m, thats with WiFi, phone calls, MMS, 3g, internet browsing/showing it off to mates in the pub and then listening to an album on spotify in the car.
Considering this is a new battery and it still needs several charges before it is working at full capacity, I think that is pretty good for a smart phone! It can only get better, right?
JuiceDefender - I can't recommend this app enough, I don't want to mess about with Task Killers (that don't really save battery), I don't want to stop stuff syncing (because thats the whole point of this phone) but I want to optimize my battery life to get me through the day and this app does it so well!
I've currently got it setup to turn 2g/3g off when in standby but set to turn data back on every 5mins for 30s to allow apps to sync. You can specify a longer interval which will obviously save more battery over the course of a day. The phone connects back to a 2/3g connection so quick when you bring it out of standby so your not waiting around to get back online.
Switch on WiFi at known locations - I have this setup because at home, 3g signal is a bit patchy and it probably uses more battery constantly trying to get a 3g signal all the time, than it does if it is just connected to WiFi.
Turn data off between 2am-8am while I am sleeping.
Turn data off when battery is below 15% - with my G1 it would hit 15% just as I'd be heading home on the train in the evening, so I'd turn data off just so I could send a few texts or so I had just enough battery to make a call. So I figured I might as well use that last 15% battery for basic phone operation and give me enough battery to get home! I probably don't need this with the Desire though.
Any one else using JuiceDefender?

WOW, can I have your battery please ...
What did u do to get this powerhouse. Was it weaker in the begining and got better with charges or was it like this from the begining?
I dont use GPS at all. Only for navigation, when in car and then it is on charge. Normal day.. no gps, no auto data connection - do it manually when internet connecttion is neede. But battery doesn't last a day, merely 12-14 hours. Charged 3 times yet, only 3 days old Desire.
I cant find juice defender in the market?
When I first got my Hero I remember my battery life being terrible, most of it was down to fiddling all the time, however over time my usage changed and the battery had been charged a lot the life was a lot better. Also there were a number of radio upgrades installed, which probably helped.
Since I've got my Desire, the "desire" to fiddle hasn't stopped and I feel as if I'm in the same situation as I was with the Hero.
My opinion is that over time the battery life will be better, as with the Hero.

Yes both Ultimate Juice and Juice Defender are in the Market.
Juice defender was missing for me a couple of hours ago. But actually, when I installed it thinkgs started to go wrong for me. May be a coincidence, or may be a conflict with some other sw.
Following shocking power drain, I have hard reset, and left it with nothing syncing and all networking disabled. As you'd expect, battery level is barely falling in standby. Now to start adding things back in and see what efects it has. First step is to spend 30 mins browsing over 3g, previously this would take out 10% of my battery.

It's not there for me either currently, neither is mybackup pro... :/
ok so I used my phone for about 3 hours last night tweaking things and playing with stuff and didn't charge it overnight and used it a bunch today and the battery indicator looked like it was at about 70%. probably not accurate, but the fact that it's even still on amazes me because it's probably got 8 hours of playing with it and 6 hours of standby and still going strong.
I think a full drain then a full charge might reset the battery indicator for accuracy, I wish we had like a "current widget" for WP7 to see the ma drain.
how you guys doing on HD2 WP7 battery drain? Mine seems to be even better than WM6.5
I have the exact opposite experience as you. My HD2[7]'s battery life is crap. It was fully charged last night and I had left it in my drawer with the Wi-fi off. After coming from work a half hour ago, I saw that the battery was almost drained.
Also, shouldn't the battery icon show the plug when the phone is being charged? My phone is on and booted into WP7, the red light is showing but the battery icon shows no animation or the plug. EDIT: WTF IT FROZE ON ME, I had to remove the battery!
Finally, what's with the random reboots? I've seen 2 already.

I think its something related to the SD cards you are using.
If the Sd card you are using is not compatible with WP7 then you will get random reboots.
And the main thing here is that there is no specific way to know which SD card will work and which wont work with WP7
By the way my battery is somewhat draining faster than the Android I was using on my HD2

What I meant to say was, we don't know which SD card will work with WP7 on HD2.
I wasn't talking about the official WP7
Well the stock 16gig TMOUS card works just fine.
my battery seems to be fine, i use my scale based on my school schedual. with android from 7 am to 4 pm around 50 to 40 percent.
today running wp7 i unplugged it around 8is and about 6 is it had very little black on the battery icon. im going ot charge it up fully, then kill it, to see if that helps reset the battery stats
Well when i first flashed WP7 my battery was over lasting.. After i manually rebooted because i just felt like doing so, my battery has started to drain a little bit to fast.
Are there any marketplace apps that can monitor this stuff yet?
Update: Last night, after making sure that my phone was fully charged, I turned off the wifi and removed the SIM card and didn't touch the phone again until a half hour ago (about 12 hours standby time in total). The indicator is showing about 50% battery life remaining. This SUCKS, and any helpful comments about this will be appreciated.
just considering its not supposed to be on the phone...
also what theme are you using
and since microsd polling it may have a lot of impact on standard battery life...
plus, let's be real, it is an htc...they're not battery efficient

Here are my settings: Dark background theme, purple (hate the color normally, but somehow manages to look nice on the HD2), 30 seconds lockscreen timeout, Wifi off, Location off.
I tried removing the MicroSD, but the phone then becomes unusable with frequent freezes and reboots. I'd love to check if the card is affecting battery life if the damn phone would let me to.

HTC puts bad batteries in their 4.3" phones. They've been using 1230 mAh batteries forever (over a year). Blackberry curves come with 1150 mAh batteries so you can see what that size is somewhat optimized for: feature phones and smartphones with small non-touch screens.
Most smartphones with a 4"+ screen running Android or WP7 have 1400+ mAh batteries (the i4 and Droid X also have 1400, Galaxy S and Incredible have 1500). That's why the battery life is bad.
And it's also the reason why I've never really given the phone much consideration - the battery and the TFT LCD screen they used on it.
That being said, the battery life depends on you usage. When I used my HD2 as myprimary device the battery life was terrible. Once I got my Vibrant and used it only as a PMP, the battery life was terrific because it didn't have a SIM Card and I only used it on WiFi and to play Music and Videos.
But people who use Curve 3Gs as their primary devices and are constantly BBMing and/or SMSing people in addition to calls report days-worth of uptime (emphasis on the plural).
My battery life is on par with what it was on android (about 12-16 hours with moderate usage of web, email, facebook, and heavy twitter) and its configured the same was as my android:
1) wifi is on when I need it (maybe 20-45 minutes a day for some marketplace downloads or something)
2) location is always on
3) screen is set to manual, low and 3 minute time-out
4) I have 3 IMAP email accounts that check between every 15 minutes and every 30 minutes.
5) I have a VERY active twitter account that updates every few minutes (not sure exactly as it doesn't appear to be live tile integrated)
6) facebook and google sync
7) HTC HUB is usually running updating the weather and stocks as often as it likes
8) dark brown theme
9) ringer off and no haptic feedback
Hope that helps anyone.
I do agree that the HTC supplied battery is sub-standard. Does anyone know where I can see what the battery percentage is acutally at? I only have the icon in the top right.
Just as a bit of information, my HD7 gets significantly better battery life than my sister's Galaxy phone. Also, those of you removing the SIM, make sure you also enable airplane mode, incase the phone continues to still search for signal... Battery size isn't as important as power management, though I do agree I wish we had a bigger battery on our HD7s... we might have sacrificed a little space for it though...
I think the battery meter is off. After about an hour of playing with Netflix, Zune and watching videos with the ign app my battery meter indicated that I had a lil juice left. I went to sleep without charging the phone. I was sure it would be dead when I woke but it wasn't. I was able to get about 2 more hrs out of it while using the Zune player streaming a playlist I saw.

There is no third party multi-tasking in WP7 and Android Users usually have more apps/services updating stuff in the background. Yes, WP7 will get better battery life than lots of Android Phones and even theHD2 with the same battery in it due to that simple fact along, nevermind all the other exceptions and the obvious disclaimer: different use patterns are different.

I have ATK or whatever it is installed on her phone, not sure if the AMOLED screen uses more juice though
Don't get me started on task killers and android. ATK may be causing the poor battery life. Those process and apps you think your killing are just gonna restart and cause more battery drain. Android does not need task killers. I suggest trying auto killer wich tweaks androids internal memory management to be more or less aggrsive. Phone must be rooted though.

Hi
Had my phone a little over 24 hours and I may have a very poor battery
I have a LIVE screen on the one with the water and the leaves plus, I haven't made or received any calls but I have used it a little for internet and a few text messages
The green bar was on full about 5 hours ago and if I had to guess how long my use has been I would say 30 mins in total of the 5 hours, now my battery is indicating less than half full
Imagine if I was out all day making and receiving calls?
Does this sound normal?
This is normal for the first week or two , the battery is adjusting itself to your needs
Sent from my HTC Desire using XDA App
It's absolutely normal and you'll really notice a difference in about ten days, a couple of weeks the most.
That said, live wallpapers do use more battery. I much prefer a static dark one
adding to that make sure your phones nicely drained before recharging to ensure you get a nice full charge for next time... i took my desire's battery at least 5 days to start having a long term charge
bettery
same here took a week also what really helped me is having advanced task killer and setting it to kill unwanted apps after i lock the screen
i dont think you should use task killer, the apps will end them selves, i used task killer and got alot of force close after and errors etc
however force stopping unwanted applications is also good.

5 H 55M 55S unplugged, hahaha no joke its all 5's
and now my battery is almost dead surely this cant be right
has anyone ever been given a replacement battery for their phone or do they ask for the phone to be returned if this is infact a fault
Battery sucks, phone is power hungry. Get used to it
I've had 2 desires since a week after it was released, i can count on one hand how many times I've got through a day without plugging my phone in.
I get about 2 days on my phone if I don't mess around with it a lot or get many calls. I normally plug it on overnight. Every night.
Nowadays that seems normal for a smartphone. Personally I think the battery life is slightly better than the iPhone 3GS.
Angry Birds means it lasts about 4-5 hours...

It's all down to how your using your phone. If you have a live wallpaper and many widgets and apps that run in the background like running in the notification bar, then yes, your phone will die pretty fast. Also it depends on how much CPU your burning. When I first got my Desire, I was like WTF. This is useless battery life and was starting to play hell. Now it's fine. I can leave it for 2 days easily if I just text or flick through settings. It just depends on what your running.
BTW, no one should have a task killer. It defeats the purpose of Android. You can get a lot of force closes and other things. Just leave them alone and let the OS handle the apps. Android does end the process if it's idle, eventually, but it's not using anything really other than a bit of memory just to keep it going a little.
As GoogleJelly pointed out, it really does depend on what you do with your phone and what's apps/processes are running on it while the device is using battery. Even I found the battery life pretty poor at the beginning...I found it quite annoying having to charge this thing nearly every day.
After some light tweaking, I managed to get the battery life to go over 3 days and I now have no reason to complain about my phone Mind you, I'm not a heavy user....As for background apps, I think i've got about 5/6 apps running at a time...
EDIT: I've attached a screenshot of my battery meter.....
What app are you using to view your battey history?
I also tested task killer when I got my phone. I thought it was fixing battery life, but after bedding the phone in a bit I took it off to see how much difference it would make and I didnt notice any difference at all...

I configured Quick Battery app to go to battery history from my phone settings every time I tap on it. You can view your battery history through:
Settings > About phone > Battery use.
If you want the graph, just tap on the top layer which shows the length of time you've been on battery.
EDIT: This works for Gingerbread based ROMs (it's the standard feature lol)...can't remember this being on Froyo.

This is irrelevant with Li-ion as this is a myth from the ages of NiMh batteries. Your battery will not get ruined if you don't discharge it completely before first charging.

Ah right, cheers for that. Didn't know it was all built in
One of the main reasons why new smartphone owners experience fast battery drain lies in the simple fact that they fill up seven homescreens with widgets that sync over mobile internet every hour or even more often, which really kills the poor juice like a massive gas leak.
After about half a year of use I've reached a stage where I use just 2 screens on my Desire (CM 6.1.1), of which page no2 is a full 4x5 agenda and Page one has just one actively updated widget (home weather).
Combined with restricting network usage of random apps by means of DroidWall and underclocking the processor at certain parameters (eg. battery <50%) the phone lives for 2 days pretty easily, with moderate browsing, music etc included.
But TBH I've really decided that the battery usage is absolutely random because some days it just drains like there's no tomorrow with no apparent reason that I've been able to identify. Carry a spare microUSB wire tbh :/
I read so much myths in this thread concerning Li-Ion batteries.
First of all Li-Ion batteries do have instantly the capacity they are intended for. Even 5 charges won't change that. The only thing which can change over time and charge-cycles is your phone recognizing a new voltage level as "full" (read more: "calibrating htc desire battery") or you playing less with the phone or having power-consuming apps uninstalled.
Also a full first charge is not necessary. This "requirement" are from past days with NiCd or NiMH battery-types.

The calibration during the initial week or so of using the phone arises from phone-side calibration, not the battery itself, which is why deleting battery stats from recovery can at times resolve battery issues :V
Phone didn't last half a day after flashing CM 6.1.1; after a couple of days I charged it to 100%, deleted the stats and voila, it's about as perfect as a terrible smartphone battery can get.
I think the most complained about issue with SGSII is the battery.
But is it such a big issue.
My situation : Inspite of heavy use I usually make an entire work day with atleast 10-20% battery left.
I always have a micro usb cable in my locker at work which is an emergency back up.
The reason for poll : To correct my ignorance as I think majority of people are unnecessarily complaining
I'm with you, OP.
Certainly, the battery life of the GS2 is unimpressive. I would even agree if someone said that the battery life is below average.
But it does seems like a lot of people who complain about the battery life just have unrealistic expectations. Using the phone will lower the battery level. That seems pretty natural to me. If you're going to keep the display on for over an hour, you can't expect the battery level to dip just 1% or 2%.
Then there are people who talk about the Android-OS bug. They show some impressive data on usage depending on scenarios. It's an interesting read and I understand what they're trying to say. But at the end of the day, it doesn't really matter to me. Before I knew about the Android-OS bug, my usage patterns meant that my battery level drops to about 30% by the time I get home from work. After I read about the Android-OS bug, it didn't change my usage patterns and my battery performs same as before.
Sure, it would be great if the battery never dips below 90% but unless the day comes when we have tiny self-sustaining fission reactors built-in to your devices, it won't be happening. (I'm thinking about that thing that Doc Ock invented in Spiderman2, just smaller.)

You got me all excited.
I dream of the day when we have batteries the size of a grain that will last for few years, like most watches

Completely depends on usage. Generally have 30-40% remaining everyday - screen use of 3-4 hours. gmail, FB on 30 min syncs, EDGE always on. Ended up with 78% remaining on a day on which I had a lot of work to do (so less time on the phone)
Can't expect more from a smartphone at this point of time. (using Lite'ning ROM 1.5, Tegrak OC 1.4 Ghz)
Unfortunately My device battery life is poor too
I can make it most of the day through work without recharging, and that's considering having both bluetooth turned on and either music or podcasts playing most of the day, and that the building I work in being very good at blocking wireless signals, so my phone spends alot of time trying to find a connection.
Knock on wood, ive been really lucky
i have an optus ke2 that has been rooted and all ive done is remove the optus stock and other not need apps, and so far, still being at the stage where the phone gets turned on every 5 min, ive needed to charge every second day or so with brightness on full.
i love my SgsII
How many of you with bad battery life have also got an sd-card plugged in?
I've just taken mine out (class 10 16GB) and it seems to have improved battery life?
Without SD card, and with power saving mode on, I get 3 days but with only EDGE on and routine voice calls.
Facebook takes the most battery and also the browser, I feel.
BUT NO WIFI and NO 3G! Its bad, thinking of extended battery if I have to used all that stuff.
