I was wondering what others are experiencing as far as battery life on their TP2 or other variants?
My experience so far has been very disappointing. As soon as I unplugged my device and sent one text message it went down to 95% and watched it drop to 94% shortly after. 20 minutes later I'm down to 90%. I do have some things running in the background; Email (Outlook Exchange, 2 Gmail accounts that check for mail every 2 hours) and palringo mostly but that's it. I've even turned off 3G with no help. Has anybody experienced this as well or do I just have a bum battery? Please shed some light on this for me. Thanks in advance.
I sync with various sources every 15min via 3G, definitely have a bum battery.
I have the Tilt 2 and, coming from the Tilt, have been very pleased. Worked a night last night and removed the phone from charge at ~11pm. Used internet for a total of about 30 minutes and a few various apps for a short time. Used net again in browser for another 30 minutes this morning. Not a significant amount of use but right now, at 1:30pm, I am at 80% charge (standard battery meter). My Tilt would be probably 30% by now or worse. The net really seems to suck the life out of it.
I would think you have a battery issue unless you're using different battery software. It might not be reporting correctly. Either way, something's up. Good luck!
I have an unbranded Touch Pro2 and have been very pleased with the battery life on my device, it's much better than any other similar device I've had before.
I tend to leave the phone enabled for about 12 hours per day and have the device auto collect emails hourly. I have WiFi enabled all the time and frequently use the device for email, web browsing, RSS feeds etc.
Even when I've been using the device a lot I tend to get about 3-4 days' use before the battery gets low. Even then it's probably no lower than 20% so I could probably carry on a bit longer if I wanted.
I'm using a Tilt 2 and so far the battery experience has been excellent. Its so much better than the Fuze (which would nearly be dead before dinner time).
I have Outlook set to sync every 60 minutes, Windows Live set to sync every 30 minutes, and I'm a heavy texter. I also like to play with the applications when I'm bored (like Google Maps w/GPS). So I use the phone quite a bit throughout the day.
It does sound like you either have a defective battery or as someone mentioned, your battery software isn't reporting correct battery levels.
Battery Life
I have an unbranded TP2 and use it mostly just for the phone and a little bit of WiFi and one sync a day. Also play games and watch movies. The phone is unmodified and I can watch a full length movie (from the storage card) and be down only one bar on the battery. I could probably watch two full length movies without any problem. Normally I top my battery off every two days, but almost never go lower than one bar down.

Palringo could be it...
Check background processes and see if there's anything that's cpu-intensive

Try it without Palringo. From my experience with the Tilt and the Fuze it is a battery killer.
The first 2-3 days I had my Tilt2, the battery seemed to drain really fast. I even charged it up before using it like the manual said to. By the end of each day, the battery was at or below 50% which really surprised me since my Blackjack 2 would last about 3 days on a charge.
After religiously plugging it in every night when I go to bed, the battery life seems to have stabilized. I haven't done any tweaks, hacks, or ROMs other than hide a few TouchFLO screens that I won't be using. I have bluetooth, 3G, and push email enabled.
So, give it a few days and it might get better. I think it might be the battery driver trying to equalize itself or something. If you don't see an improvement, maybe a warranty exchange is in order?
Had a sprint TP2 and I was lucky if it wasn't shot by 9pm everyday. Have a tilt2 now and I'm getting about 2 days out of it.
EDIT: Not a heavy user so YMMV.
Much better than my Fuze. I could easily go two days with it. My Fuze was out of juice at the end of one day.
i've had the touch, touch pro and now using touch pro 2... i'm by far pleased and impressed by tp2... plus there is an app that somehow controls the battery life, a friend hooked me up with it... look it up
Battery life isn't bad for me. I think it a little better than my Kaiser (original Tilt).
I've traditionally done battery usage measurements for giggles, done it on my last few phones, and so far my measurements on the Tilt 2 are equivalent to the Tilt I replaced.
Backlight on 100% is a little higher, I suspect the backlight itself is brighter. The idle and standby is the same, battery usage with Flexmail online (2 online imap mailboxes) is the same, I believe the GPS was a little lower but I haven't done much testing with it yet, not significantly different.
I think it's just the battery conditioning period, plus there's the New Toy battery syndrome. Batteries tend to get worn down faster when the device is a New Toy.
not as good as it should be
I don't have much going on in this phone, it does hourly look up the emails, but by the end of a day when I rarely get or make calls, the battery is low and needs recharging. Very surprised, was expecting the two-three days' charge others above had mentioned.
Though it's not fantastic, it's a whole lot better than my Tilt, so it seems very good in comparison. If you have bad battery life, try closing CPU intensive background services, and using Advanced config, set an inactivity timeout to disconnect from HSPA/GSM (I use 5 minutes of inactivity). Also, enable most if not all of the power saving features in advanced config. Reboot, and you'll find that your battery should last longer. Also, you might want to check your radio version, as there are definately more battery intensive ones (like my current one).
I figured I'd tack onto this thread. I just got my Tilt 2 and I'm curious about battery conditioning. Is there some way that I should condition my battery during my first period of use?
thanks!

tp2 battery is one the best...if you need longer life get another battery..dont forget this is a mini pc
I'm not really having any problems with the battery. I was just wondering if there was something specific I could do with the new phone to condition the battery out of the box to make it perform at peak efficiency. I thought I read somewhere that you should fully charge and then fully drain the battery several times when you first use the phone before ever "topping it off"...
replaced mine
the battery I got in Oct 09 with the TMo TP2 was getting a full charge, then without doing much of anything but one call or one note in a 6 hr period, the battery was already at the red level of <=10%.
Called TMo about this back in Nov, then again in early January they agreed and sent a new battery. The new one is doing much much better at holding the charge. I don't know what the issue was, but that they replaced it without much question has me believing there was an upgrade in the battery technology.
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,
Fon22
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.

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... :/
Any pointers for increasing battery life? I've disabled live wallpapers, picked a dark background, set friendfeed etc to update every 4 hours, and it's still not great. Phone is new, should I expect battery life to improve as battery gets used a bit?
Are task killers worth using? Seems to be some debate that they might actually cause more problems than they solve.
I've gone through forum and found lots of generic advice but would appreciate any ideas people have tried on the Desire.
Do I *really* need to wturn off wifi when I'm not using it? Isn't the phone smart enough to not use it when a known-network isn't present?
Cheers
From my experience i would advise against having a task killer running.
I used to have one running on my N1 and thought, "Great, i can free up memory". But you really don't need to do that with Android.
Having disabled it from running, I get to teh end of the day and I have between 75 and 85 battery, after having done a fair few phone calls, some net fun and data access.
I still have a task killer but I use it infrequently and dont have it running - i let it "kill" itself after running it.
I found they take up a good deal of battery life. But that's just my opinion.

Of course!
The classic task killers kill services that are sleeping and do no eat battery.
A few minuts later, on some receivers ( connexion to internet, message or SMS received) these services will restart, and that's where they are eating battery.
If you hadn't killed them, they would have done that without eating battery.
Waking up and then going to sleep is really less battery-eater than restarting the whole service.
So, please forget about all these task killers or do that in a smart way. Only kill your game or the latest app you used!
Battery life will improve over the first weeks use. Needs a few charge cycles to achieve full capacity.
Although the battery life might not be as good as some other "imore ipopular" handsets at least you can buy a second reasonably cheap battery if you know you will be a couple of days away from a possible charge (camping etc).

You serious? I am guessing you're referring to the iPhone, the smartphone that is on charge more times than its off charge?
My Desire hands down beats an iPhone for battery life by almost 100% - only ever got 1 day of an iPhone at best - Desire is approaching nearly 2 days full usage, I am no lite user either.
For battery life the Desire is one, if not the best out there at the moment.
thank christ for that, i presume it improves after a couple of charges. mine was new on friday and the battery's pretty uninspiring so far...

My Desire has been up for 21.5 hours and has 3 bars left (according to the settings battery meter) but I've been driving around most of the day with spotify on listening to music, quite a bit of surfing, emailing, calls and a few texts.
I reckon it's probably got another 5+ hours to go yet.
My phone is quite new and battery life is starting to improve daily now.
Hmm... struggle to get more than 5 or 6 hours out if mine under relatively light usage, maybe 20 mins calls and 3 or 4 texts, if I use browser it flatten quicker still, the battery use status usually says Android OS itself has used most battery.
Hoping it will improve, at moment it is poor compared to my TD2 with a smaller battery
P.
had mine about 6 days and my battery is ver poor at the moment. however i remember thinking that about the G1 at first and it got better.
still was luck to get a full day from it. however i went to europe the other week (from uk) so turned all roaming data and syncing off and it lasted 4 days.
fingures crossed battery life increases on the desire, gor a car charger on orded fron fleabay so i should survive
i loved my G1, and found it hard to upgrade, first time thats ever happend, but wow this desire is differnt class, my wife has the iphone and is green and my 16 year old son is gutted he got the hero only 6 months ago.
Re: desire battery life
I've been running my desire for nearly two weeks now.
As usual WiFi & gps are the main culprits.
On average, I have exchange & GMAIL push on 3G all day with a bit of Facebook, sms & several min long calls without going past the three quarter mark by 5:30pm . However as soon as I switch on WiFi at home for browsing, reading news feeds, market etc, bang goes my battery!
Turn off 3G and sync and use it as a phone.......great battery life!

Yea not sure how you guys get good battery out of it. I have everything off, dark background, no synching due to having mobile network off (only thing setup to sync is email every 2 hours). I take a few phone calls maybe 30-40mins, do about 15 mins of surfing, 30 mins of music through headphones at low volume, and a game for 30 mins. That pretty much concludes my battery life for the day (is usually at around 20% left by the time I get home).
I find if I browse the market and download/install apps, my battery will go down very quickly.
Got my desire for a week now and it lasts me 2 days woth some movies, wifi and messaging. if i go even lighter, only messaging and calls it lasted me almost 4 days. it has great battery in my opinion, better than my old hd2 and even better then my old old diamond
Over in General we found an issue with the calendar app keeping the phone from going into sleep mode - That could be a cause for poor battery life.
The thread is here (remove spaces please):

My Desire have no problem on battery so far tho, 1½ day with normal use is no problem. litle use i can use it around 2 days, but with alot off things running i would say for sure it works over a full working day.
Mine has been running for 20 hours now, I have mainly been calling, texting, surfing the net (mainly facebook), and playing a game a couple of times.
I'm not really sure whether this is good or not, I would rather it lasted longer than this, as it is due for a charge within the next few hours, and this is a bit of an awkward time to need to charge it. If I wasn't off work today I'd have a dead phone before I got home.
I don't like to charge mine before it tells me too, I like to think it'll improve the battery life over time? Is this right?
those batteries are not affected by memory effect. charging everytime you can is better than drain battery to 0%
HTC have said there is a software issue with battery levels hench the charging issues. Fix in the future they suggested.
Weather this effects the actual life of battery not sure.
I have just come from the HD2
At the beginning, everyone agreed that the battery life was god awful, and a month or so in everyone reported that the battery life was outstanding!
I can confirm this, to start with it wouldnt last me a day, by the end of it i could leave 3g and wifi on all day with everything running in the background and get a good 2 full days out of it!
I just received the desire yesterday, i gave it a full overnight charge and i must report that for the first charge the battery life looks very promising
I have used the phone VERY heavily even for me with about 100 texts, an hour talking, an hour on the internet and syncing every 15 mins or so and i have 2 bars of battery left, and i said, the battery is only going to get better!
You should look at power management tips for the HD2 as most of them apply, for example disabling 'automatic backlght' and setting it yourself because that alone can add about 30% to your battery life.
currently at 2 days 15 hours with 6/10 battery bars left.
i have gps/wifi/internet disabled and turn them on with the settings widgets when i want to use them. screen brightness at about 20%
the battery is great IMO
Guys could u please tell if I should when receiving my phone charge it directly (full charge) or it's better to empty it completely and then charge it ?
Thanx
As I posted in another thread:
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.
Click to expand...

I am rooted, S-OFF, using the Sense Modaco ROM. Battery usage was no better with the Stock Bell Rom before rooting or S-OFF.
My main concern is the screen flickering at low brightness. it's as if it's unable to decide on a specific level of brightness and makes me question if it's actually saving any power.
I set my phone to Auto brightness and I am going to see if that is actually worse of if it's on par with 20%.
Ugh - just realized there is another thread pretty much all about this. I thought it was a different issue. Still, does anyone know if there is a better batch of phones or something? I have a FutureShop warranty so it'd be easy enough for me to replace if it will actually provide a solution
No-one has posted anything, to my knowledge, about a different batch of phones having better battery life. I would check out the other threads about battery life (including those on the G2 side too) and see if you can get yours to last better. But it could just be something faulty on your phone/battery.
Auto-brightness would make it even worse..because there is some type of bug or something that isn't making it function like it should. I was also getting terrible battery life until I followed some of these steps: http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
Biggest killers are any widgets that are constantly updating..or facebook/twitter apps that are constantly updating. As well..i recommend SetCPU to underclock your phone when your screen is turned off. This should also help with conserving battery life along with some of the steps provided in that link.

I am considering waiting a month or so and then having mine replaced. Unless I managed to figure something else out. My HTC Legend had better battery life.

The reason I want to try auto or higher brightness is to see if lowering it was actually saving me any battery life. I am curious if there's a driver or display issues that causes it to use the same amount regardless of the setting. So far I don't seem to be running out any faster @ auto than I was at 20%, but it hasn't been a long enough time to tell for sure.
Also I am unable to do the battery tip for the evo because once I turn off the phone and go to charge it again, it's instantly green. But I am going to try it anyway even though it's green.
Since writing the first post I used the OC module to get my phone to 1.2ghz. I have SetCPU set to run on boot with the onDemand setting. I have a profile that says to slow the CPU when the screen is off. From what I've read it doesn't make a ton of difference with this particular phone, but we'll see...

Yep, that's what I found too, when you try and charge it thinks it's already charged and goes green straight away again. But as you said, worth a try.
I just wanted to report back and say that I had my phone replaced. So far so good:
- No screen flicker issue at low brightness
- Battery has lasted nearly 20 hours with moderate-heavy use (played NFS Shift, setup basically everything on the phone after rooting, installed all my apps, backups, flashed some roms, 20+ texts, 3-4 short calls, showing people random apps.)
If it's not all in my head then this is definitely much better now!
Curious. It seems that everyone who reports the screen flickering problem has poor battery life.
Defective displays?
I feel my battery life is pretty bad as well. I've unplugged the phone this morning at 7 AM. Now it's 2 PM, and I'm at 37%. In between, the only things I've done are: send/receive a few emails and chat on gtalk. Brightness is at 40%, animations are turned off, wifi and gps location off. Using latest Cyanogenmod (6.1.1) and have no screen flicker issues
Edit: 17 minutes later, it's now at 27%
How long have you had the phone for?
Initially the first few days I got the phone, battery life was really bad, could drain in a few hours.
After a week or two of use, I now have reasonable battery life, the phone can last all day with light usage and still have lots of juice left. Actually I think if you make a few calls and a few txts, battery could last 2 days. If you play with it, one day for sure but you need to plug in over night.
(if you're talking to me) It's quite new, just picked it up on Friday actually. Also I've kept on researching, and it seems that poor coverage (like I have at work, from 7 til 3) tends to drain the battery even more, since the phone keeps switching between HSPA, 3G, etc.
I had my first one for about a month at least. This replacement was from Saturday.
Today I've had my phone unplugged since 8am, it's 5:30pm and I have 45% battery left, but the screen is the #2 user. Standby is #1 @ 40% of my battery usage, due to over 4 hours of time without a signal. The screen is only 24% and has been on for 48 minutes. Voice calls is #3 at 23% battery usage, with 23mins of calling.
My other phone would have died by now.
Also I spent an hour of streaming bluetooth audio to my car. Bluetooth doesn't even register on the battery usage. I've never seen it use more than 2% and it's always on. I am not sure why people say it uses a lot.
Just want to share my experience.
I too had poor battery life. Stock Bell ROM. Got to 3:00 pm and it used to die. Use this for work. Pushing data all day from Exchange server, bluetooth on all day because I'm in and out of the car, talk on average 30 minutes per day, texting, surfing, tethering, blah blah. Believe it or not, my old Omnia II would get me thru the day no problem.
I was also tempted to return it. But I decided to try a few things. Installed Set CPU and a task killer at the same time. Shut down as many tasks as possible on start up. Widgets and accounts, except Exchange-push, run and sync every hour. I get about 40% battery by dinner. I am happy now .
I'm quite happy with my Desire Z's battery life, It lasts for about 36 hours with moderate use. I have Juicedefender and Ultimatejuice installed, data or wifi are opened only when an app needs data connection, this increased my battery life by 10 hours or sth like that. Nice app.
I had terrible battery life until I went overseas. It is a stock Bell ROM, but I arrived in Spain Monday and am using a Spanish SIM card.
My battery life has increased from 14 hours with Bell's 3G signal to my current 27 hours and 35% remaining battery using GSM and WiFi always on. Funny thing is that no matter where I am it says the screen is by far my biggest power drain.
Where did you buy your Desire Z and how did you get it replaced? I'm with Bell and they would take mine to send out for "repair" but not sure if that will do anything. This will take 3-6 weeks apparently and I'm not sure if they it is worth it.
I'm running 10 hours with that I consider fair usage (few calls, text, map/gsp, and facebook.) My display is the highest battery usage at 60% and on for about 1:45h. I'm very disappointed.
Hey,
it's the same with my G2.
Max 24h.
I've standard ROM installed.
No WiFi.
Brightness to about 30%.
Juice Defender is installed and I'm surfing and just the regular stuff, but even if it's just in standby, it's taking a lot of power (display takes most)
Best!

I bought mine at FutureShop since I didn't think Bell would let me without buying at least a month of service (or being an existing customer). I also purchased FutureShop's extended warranty which is how I was able to get it swapped for a new one so quickly.
I use the extended battery for the evo. Lasts about 1.5 days with ass loads of use. Just have to trim the plastic edges a bit.

I have a couple of those red chichitech batteries but I wasn't able to notice any improvement with the problem phone.
My Desire Z also has a flickering screen at lowest brightness, and with moderate use it dies after about 12 hours max. Even on lowest brightness the screen ueses 59% battery. I rarely manage to make it through the day without having to charge the phone. Im on stock ROM with latest OTA (1.72) btw.
Gonna have it replaced next week just cause of the flickering screen. Has anyone tried the 1700mAH battery from seidio?
I haven't been able to find any threads that already cover this. There are several reviews, users' opinions etc on how long the battery in a particular smartphone lasts, but it's always struck me as odd that this information isn't easy to compare - it could lead to name-and-shame for particularly bad phones or encouraging results for those manufacturers who actually cared & made improvements.
I've found a few people who had the same idea, and one of them (being a much more web-capable person than me) actually made a website for this purpose. I really don't want this to sound like advertising, because the purpose isn't to make anyone any money, but simply to centralise this kind of information and have some (arguably) more meaningful stats driven by and for the benefit of everyone who wants to know.
If you think this could work & be a good idea, please take a look at the site - http://www.wewantbatterylife.com/ . If you think it's a rubbish idea and/or have objections, flame away.
the li-ion batteries normaly have longer life than the old phones...so it will last enough time..u'll probably replace your phone before the battery dies Probably u can ruin it with overclocking your device or something..but draining is something else
ps: im trollling again :O
Hehe, I meant battery life as in "how long does your battery last from a full charge until it runs out?", but yes, mini-troll It's all good..
Hi,
I have another question about batterie life. I don't know if it has been already treated somewhere else in the forum.
I will receive the 2000mha batterie today. What is the best way to calibrate it?
Fully discharge it then full charge or full charge before first use?
Thanks for you help!

my battery in nexus s long about 4 houres in full use , that is problem ?
what can i do ?
Nice site, and it will only grow more useful the more people input their info. Although looking at the results, some of those 30+ hour claims seem outlandish.
my stock galaxy note battery takes me 6 hours to lose 50%. hope it could last longer.
On my Galaxy S running ICS 4.0.4 Dark Knight 2.2, my battery lose about 25% by day. But with light use (1 or 2 calls, some SMS, GMail sync, ...)
really miss the days with my old nokia which i only needed to charge every two or three days haha.....

my phone keep charged almost 1 day
I don't know if it happen for someone else but i noticed a sort of "bug" with my HTC HD7. (Bought in December 2010)
If i reboot my phone when the charge is at X%, after the reboot, the charge level will be ~10% less than X ... and the phone will stay a very very long time at this percentage.
(For exemple, if after a reboot, i'm at 75%, the battery could stay at this level for all the day)
So as I imagine, it decalibrates the battery level and to make a new time the calibration i have to let my phone fully discharge and fully recharge to solve this bug.
Strange ...
(Sorry for my english guys, I hope i can be understand)
It seems that smartphones need more juice daily. However if you disconnect the mobile packet data whenever you are in range of WLAN you might get 2 days with one charge.
I am actually quite amazed how well my Samsung Galaxy S1 original battery has lasted almost 2 years. When I first started this smartphone journey with my S1 I thought that it will not last one year. I am glad that I was proven wrong.
Batteries
Definetely Smartphones need better batteries, especialy after we got used on some phones to last even 4 days like I had previously Nokia C7, and after that i bought Galaxy S2, and its battery lasts only 1 day, now thats really sad
my sgs+ with a custom rom (gigabread+) is alive up to 24 h.
My I9001 is at 30% at the end of the day (connected to wifi all the time)
battery life xperia s
my xperia s last 3 days with making some calls abou ta half an hour surfing on 3g a day and sometimes a game but when i use it a lot is lasts about one day and a half
HTC HD2 on nand android does ~4-6mah an hour on standbay, depending on torture i give it, it lasts a day to a day and half
My Samsung Note (stock 4.0.3), WiFi on all day, and average use (business mail, whats-app, games, some browsing)
after 15 hours the battery is still 40%~50%
i use SetCPU, it throttles up the CPU if its needed, at idle it runs at 200 MHz instead of 1.4 GHz
My SGS2 can last almost 2 days without using data. Its pretty good on battery
