I got my Desire in april and ever since I've never managed to get the battery to last more than a day.
I've tried different ROMs (Defrost, OpenDesire with and without Sense, MoDaCo r4, DJDroid, Neophyte, Pays-rom 2.1) but it's always the same: almost no drain in sleep mode but as soon as I turn the screen on and start using it the battery goes down ~20% every hour. I don't believe that's normal since some people get 3-4 days out of their battery.
For example, today my phone has been on for 2½ hours and lost 43% battery with WiFi on, just surfing the net and using Tapatalk.
The screen brightness is fixed at 30%, auto-sync off, bluetooth off, network mode set to WCDMA only and I have good 3G reception where I live.
I have no clue what to do, maybe someone else does?
I have the same life spend for my battery. I think its quite normal for desire. Unless I'm abnormal too : x

You can use setCPU to underclock the processor or to create rules to make it powersaver.
I (as many other people) have one for setting the max/min processor to 245MHz when the screen is off, so it doesnt waste so much battery. I havent tested a lot, since I did it yesterday but the battery is lasting longer.
Also there are different ROMs that have better battery life...

I'm using neophyte 1.3 now since it was said to give you good battery time but I don't think SetCPU works with it...

I use JuiceDefender. Just by installing the free app from the market, I've increased my battery by 1.5x what it was originally.
With Ultimate Juice installed, I saw an increase of up to 2.5x.
Sods law, I can't purchase anything via the market due to having a Google Apps email account :|

I've tried it but it's not helping since I'm not syncing anything automatically anyway and the battery isn't drained with screen off.
It's when I start using the phone my battery percentage goes bananas.
And btw I know how you feel, I live in Sweden and we don't have paid apps here. Thank god for MarketAccess.

My Desire was acting like that during my first 2 days of usage. The battery was draining really fast even in standby mode. I installed advanced task killers and after that the battery improved. I do not know if it is because this app or there were some other configurations that I accidentally did...
But the battery life right now is way better than before (even lasts longer than my previous iphone 3gs). Hope this helps =D
I have pretty decent battery life and I use the stock unrooted unmodified rom. Some apps completely obliterate battery life. I used to keep eBuddy open, but I found that it kills my battery faster then anything else.

Just downloaded setcpu to take a look. Should I be looking to use the default settings or is there something I should be changing?

Hmm, when you say "just surfing the net", you're actually using WiFI + AMOLED + CPU, which are 3 of the biggest battery drains on the device.
IME, you can get days out of the phone, but if you actually have the screen turned on all of the time (i.e. you're actually using the phone), then 20% per hour probably isn't that insane. After all, that's 5 hours of continuous use, which isn't too awful from a modern smart phone.
Honestly, I think the answer might be "Yes, it does that" and "you'll probably need to charge it during the day". I've taken to charging mine on the way to work and back again (about 45 mins each way) and I'm still at 90% at bedtime.
Oh, and forget JuiceDefender. Yes, it makes a difference...but only when the screen is turned off. As soon as you start using it (and that's what you're obviously doing here), it shifts out of the way. Once I realised this, I uninstalled it...never looked back.

Oh, couple of other notes. Bluetooth doesn't make that much difference unless you're actually using it. 3G uses quite a bit more power compared to 2G. Consider switching to 2G when you're on WiFi. (sadly, no automated way to do this )
i am not using any of these tools.
i have wifi always on 3g on
no live wallpaper and push mail (k-9) with 2 accounts
my battery lasts 1,5-2 days. with phone turned off during the night. 0am till 7am.
i am surfing a lot and writing a lot emails.

Okay so I guess it's normal, I guess I'll just have to fire up the ol' charger a bit more often then
Btw I don't use JuiceDefender anymore either, didn't make any difference other than the widget claiming to have increased your battery time

Here comes a hint:
Turn off ALL unnecessary widgets like "Bluetooth", "GPS", "WiFi". Turn off also "Mobile"-internet widget, and turn it on only when u want to update some apps or check your mail.
I have noticet that "Mobile"-internet widget drains hell of a lot battery, but if u turn it off now and then u will have ure phone, like I had, for 6 days - with one charge!

Hi,
I'm planning on buying a Desire HD, but just curious about battery life before I lay down a grand on it.
At the moment I have an HTC Hero, when they were in their heyday many people complained about the short life on them. I can get 2 days out of mine, with syncing over wifi enabled the whole time. I put the complaints down to people with background apps sucking CPU or too much twitter/facebook/whatever crap syncing as well.
Now most of the reports of poor Desire HD battery I life are from people on their first charge (who clearly don't understand the characteristics of Li-ion batteries), people who expect to be able to thrash the phone all day with the screen on without it dying and generally people who just don't sound like they know what they're talking about.
I know there are two bugs which peg the CPU at 100%, the one fixed by having debugging on and the calendar bug, which sounds like it can be fixed by clearing calendar data or leaving syncing off. I think these were affecting some of the people who were complaining about the short battery life.
So my question for Desire HD owners is, can you last at least 6 am till 10 pm with a bit of use (something like 10 min browsing, 20 min IM, email syncing all day, 1 hr music, 20 min calls) without it dying? Currently my Hero does this fine and a full day without a charge is a requirement for me.
Thanks.
Yes, if you set it up correctly. From your post it sounds like you know what your doing when setting it up.
Before i tried the battery calibration i was getting from 8am to 9pm with moderate usage. TBH i was put off by using it as I thought it would just die on me too soon.
After the calibration (search forum for it) i got from 8am to 4pm the following day where the 15% warning hit. So do the calibration and you'll be as happy as i now am with it. I never got my iPhone 4 to last that long!
Thanks for the info guys, exactly what I wanted to hear!
I haven't taken any precautions to save battery life and I am getting 25-26 hours on a full charge...and now having had the phone for 2-3 weeks it seems to be getting even better!! I've been getting 36 hours out of a full charge these past 3 days.
I do not turn wifi off. I have screen brightness on auto. Syncing lots of stuff hourly (even weather!). I use 3g when I go out but this is about 2-3 hours tops on week days cause I have wifi everywhere i go. battery life has never been an issue for me and I use my phone frequently...play games for 20-30 mins. watch videos via. skynews, listen to some music etc. etc.
As for the bugs...I do not have usb debugging turned on and I have never had the /INIT problem...perhaps it was fixed in the last update? and the calender bug...never had that problem either and I use my calander with google calander, facebook, holidays and person agenda.
I think you'll easily last a day with the usage you mention. As a rule, I think you normally get up to 4 hours display on usage off a charge (browsing, messaging, watching vids etc).
I'm travelling from Ireland to NZ on Monday, which will equate to 36 hours travelling with probably no access to a charge, and lots of time spent sitting around using my dhd. There's no way the phone will last right through, so have bought a 5000mAh USB battery pack for £20.

Well...I think I have had similar results....
flash one of the custom roms, with one of the OCUV kernels and setting max. speed to one of the UV speeds (mine is set to 1.1 Ghz which is UV 50mV), also setup useful profiles in Setcpu (I have set screen-off to use max 384 mhz - which does cause a 1-3 sec lag when screen is on again) and <20% battery etc...
of course, if you play heavily with your dhd you will not get these results, so you can put wifi on with this , but need to think of what you want to do, because using your DHD for 2 days, does require limited screen usage (imho, this uses a lot of battery)

even 2-4 hours whilst using it is terrible!!! When I got my HD and unpacked it I didn't put it down after a full charge and I got 8 and a half hours with non-stop heavy use.
I think you have a faulty battery!!

I too moved from a Hero to a DHD and I can say that with similar usage, the DHD loses to the Hero by a decent margin..maybe u might get a couple of hours less of usage compared to the Hero but the difference isn't very drastic
Moreover on the Hero I'm using CM6.1 Froyo overclocked and the DHD is on Sense, so logically speaking the Hero should get slightly better battery life on CM6.1 compared to Sense. I'm sure after rooting and flashing CM6.1 and undervolting/underclock the DHD, i'd get better battery life because the DHD is like much much faster than the Hero, so I'm sure even if i underclock it, it'll still be super fast.

The battery is 'fine' i'm using current widget to track and its performing to around 1100 mah which is not too far below spec. The problem is the current draw. In use i'm drawing 500 to 800 mA and in standby around 80 to 300 mA. These figures are consistent with the battery life I'm seeing and the battery working close to spec (1230mAh i think?)
There are lots of bundled apps like Maps running all the time in standby drawing current and I haven't yet figured out how to stop them. Stopping them with task manager just sees them restart with even bigger current draw.

Something is definitely wrong (as I'm sure you're aware) with only 9 hours on standby.
Out of interest, remove ALL widgets and see what difference it makes. Also, give us an example of what processes are running?
I would get rid of all task killers and also anything monitoring your system. Those themselves can draw more than you think.

wow well I'm no battery expert but it really sounds like something is not right there. I don't have any battery drain from apps in standby and I do use maps.
I got 1 day and 16 hours from a full charge today (just put it back on charge now).
Thats with wifi on for 31 hours (always on, doesnt sleep when the screen locks), 1 hour and 24 mins of talk time and the screen on for 4 hours and 5 mins.

thats definitely wrong somehow.. should never drain that much, perhaps it is because you let currentwidget drain it all the time
(na dont know why it is like that but it definitely is way too high)
official firmware, medium screen brightness, default sync widgets
heavy use: 12-15 hours
light use: 24 to 36 hours
this is how its been for me ever since the battery calibrated, needs around a week or use the battery calibration trick
I too have just moved from a Hero (running VillainRom 12) to the DHD (stock Sense over FroYo) and even though I have only had it a week, the battery easily lasts a whole day with the moderate use you describe. Unless I get stuck into a session of " Angry Birds ", which seems to kill the battery pretty fast. But ABs had the same affect on my Hero. Constant screen time on that beautiful 4.3" display sucks the battery. I find the same thing when using the DHD as an in-car gps. The warmth of the back of the case is testament to how much energy has been expended. So I connect to the car charger now. I have also bought a portable backup battery (plugs into the microUSB) just in case.
I don't regret spending NZD1000 on the DHD. My son is looking forward to inheriting the Hero.
Well I charged it up overnight when I got it, my first full day was today and I got 7 am till 8:30 pm using it almost constantly (quiet day at work). I don't know how people can run them flat a day with normal use. And I know it'll improve a lot after a few charge cycles.
It doesn't look like it's going to be much worse than my Hero.
Thanks for all the advice. I uninstalled all widgets and it improved a little. But still things like maps/maps sync were constantly burning juice and no way of stopping them running.
I installed Launcher Pro and can report that my battery life has approximately doubled. Typically i was getting 4 - 6 hrs use and sometimes only 2 (light use). Now getting between 8 and 12 hours of fairly heavy use. Its still not up to some of the figures others are reporting but Launcher Pro has helped a lot as all those constantly running apps that were draining my battery just dont start themselves up any more!

Currently I have cm nightly 12 on my phone with incredikernel 2/27 and having a hard time finding this amaging battery life everyone is talking about.
I have screen brightness down and disable autosync using the power control widget. I have one widget, five icons and one screen. I have smartass governor on with 128/998 settings.
I also am using an extended life China battery. It had decent life with stock sense rom + incredikernel but still was not great.
Is it the battery? Is it my settings? Am I doing something wrong? Any help would be appreciated.
Thanks!

The batteries im using are 3500mah batteries i bought from ebay. I've been charging them occasionally in a wall charger.
Sent from my ADR6300 using XDA App
My guess is that it is your battery. The OEM 1300mah battery that came with the INC is probably better than that crappy no-name brand. I have the stock, used incredikernel and i was able to get almost 2 full days out of it with CM7.
EDIT: saw you have the 3500mah, most likely that is only about 75% of what is advertised. So its probably about 2700mah. How much do you use the phone throughout the day?
Not much... Thru the week it stays in my pocket with screen off.
On the weekends I check dealnews and might get in a few minutes of angry birds... But its nowhere near the claims made of 20-40 hours of moderate use.
Feels like its jumping 3% with every web page.
Sent from my ADR6300 using XDA App
I took it off the charger 5 minutes ago, down to 95% and battery usage states 72% is due to the display.
Went in there and turned off animations to see if that helps.
I also found out with clock work install awhile ago, I have an slcd screen. Im assuming they get worse battery life than amoled?

No change .... now down to 90% and screen has been off.

It may just be that battery is really horrible. Do you still have your stock battery. Try using that and see the life you get out of it. I just have a feeling, no reason why, but that battery you got is a real dud.
And yes the SLCD screens do use up more power than the AMOLED screens. I don't know if it's that much, I doubt it, maybe try with the stock CM7 kernel and see what kind of life you get?
Bump charging, even if it's only for 20 minutes while you shower and shave and eat breakfast, will really help your battery life all day. I find that if I don't do it I see my battery losing its charge much faster even after it loses its initial 5-10%
Back on my stock battery... turned off or uninstalled everything I can.
I usually leave it on the charger all night while I sleep...
Thinking about returning to stock to see if that helps battery.

What are your GPS settings? Is network location on? What about wifi is it on? If so what's your sleep policy set to. Both of these settings made my batterty drop like a brick on cm7. Another note have you used spare parts to see what is consuming your battery. Is it partial wake locks or a specific app.
Sent from my ADR6300 using XDA App
GPS off
Wifi on when I use it. I've got power control widget on my home screen. Network location is off. Wifi sleep policy is default choice (off when screen off), however I don't typically leave it on.
Haven't been in spare parts but have made it to a usage graph I didn't fully understand.
The usage I see says its all the screen. 72% display.
According to spare parts usage... over last 11m wifi has most battery usage.
Only one app with partial wake and that's craigslist Notifier. Lower than android system however.

Went back to stock cm7 kernel to see if ondemand governor is any better battery wise.
I'm still seeking this 20 hr's moderate use I keep hearing about.
Incredikernel seems to use more battery in wifi... stock is much lower.
Of course I don't know if this is fact with all the other variables.
I don't think I'm being greedy... just trying to find a setup which will afford me using my phone everyonce in awhile without living on a charger.
Sent from my ADR6300 using XDA App
!The display should be around that amount depending on how long its been running. I'm at 74% display and that with 2hr 42m of display on. It consumes the most amount of power of anything on the phone.
I've read a couple threads that cm7 has issues with the wifi sleep options and that it needs to be set to never for best battery life. At first thought it doesn't seem right be it helped me out.
In spare parts under usage stats anything jump out at you as being excessive. I doubt it but it'll let you know if an app is running to much.
Also look at the graph under setting battery if you a seeing a bunch of activity when the display is off then it could just be a lot of emails or something is syncing that we don't know about yet. If the display off and awake lines are close then you've done everything you can to Max out your battery.
At this point I suggest you try to bump charge the phone and then wipe the battery stats from cwm I was having an issue at first with cm7 n12 of my phone only charging to 94%. Maybe you are having a similar issue.
Just for comparison today was a mild day of usuage for me on the stock battery my phone has been on for 11h36m and as I said earlier a little under 3 hours of screen time. My display is around 35% brightness and I have 30% battery left. Also on a side note I'm using the incredikernel 128min and I'm under clocked to 800mhz.

with kernel 2.6.37.2 cyanogenmod+slayer it last me 24 with moderate phone use
Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...
It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost
Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.
I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.
Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).
Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.
The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.

I second this. If battery problem persist download better battery stats to see if you dont have any kernel wakelocks

Background: Rooted, stock rom.
- Just bought the phone on Saturday, charged it fully and played around with it on Sunday literally just moderate texting, making short calls, and taking a couple of pictures and the battery pretty much dies by 2 PM. Will the battery life improve over time?
This is with the settings tweaked to maximum battery conservation (15% screen brightness, NFC/S Beam off, No motion controls, battery savings on, the works.)
- Also, in that time the phone seemed to be fairly hot, I cannot recall the temperature, but it was hot to the touch. And when I tried downloading the OTA update from T-mobile, the bottom half of the phone (everything below the battery) became drastically hot. But the battery remained relatively cool. Is this something I should worry about?
I'd just like to know so I can exchange the phone while I still can.
I just got mine on Friday and I noticed the same issue. It seems to get hot whenever its doing something data intensive live streaming a youtube vid or downloading a app.
Thanks for the response.
I used it for about 15 minutes this morning reading a web page on Chrome and it seemed to get warm.
Also streamed HD YouTube as well as Spotify for about 15 minutes and it's still warm.
The thing is, these are the first really data-intensive things that I have done so far.
I'm going to go through a whole day just to see what happens.
Forgot to add that I even reduced my CPU through SetCPU to 1.2Ghz the since I rooted it
It's at 87% after 2h 20m 46s on battery.
With only 42m 23s of screen time.
It should calm down after a couple of charge cycles. For battery. Also make sure auto brightness, auto sync is off, gps, motIon control, voIce cmd, etc.
I dont use the battery saving feature and get great life. But I remember a few times it getting hot after a fresh flash but it always calmed down for me. Getting warm is normal, especially if on the charger while using.
Theres a lot of features I like but dont use much so for me its worth the few extra seconds to turn it on/off.

I am having the same issues. I got acwhite one last week and it is constantly hot near the home button. I am probably gonna revert to stock and return for another. My s2 did not do this.

Update
So I have completed my school day.
11h 25m 45s on battery
Battery percentage is at 57%.
I barely used the phone however.
Sent about 10 texts, went on Chrome and searched the web for about 15 minutes, took 8 pictures, instagram for 3 minutes.
Also kept getting e-mails (probably like 10 of them)
I turned on Power Saving mode as well.
Screen is the highest with 1h 32m 24s using 38% on my battery.
Would this be normal on the stock T-mobile rom with no updates?
I've never had an Android phone before so I wouldn't know.
But after researching, some people managed to be at around 70% usage by the end of the day. While doing more intensive tasks.
It's probably the service when you're inside buildings. If it's bad service it'll drain your battery.. if it's constantly trying to connect 4g you're going to have a short time *insert ski instructor meme*

I suggest you guys flash Exajoule. His ROM is insane on battery & its really fast as well.

I had the heats issues and ot turned out to be a borked phone. I returned for a swap and the new s3 is worlds apart from the last. Less heat and better performance

You should check to see what's consuming CPU... (long press the home button, and go into the task manager...) should see something consuming cpu...
(when my phone's warm, it's generally because something's gone psycho on cpu use...)

Or better yet in dev options turn on Show cpu Usage. In the top right corner of your screen it will show whats running.

At home, I literally get 0-2 bars. But at school I can consistently get anywhere from 1-4 bars.
This could possibly be it, but I am not too sure how much my signal fluctuates throughout the school.

I had given my local T-mobile store a call and they said that smartphones should be regularly heating.
It's strange to me how I can do a task a simple as texting and it heats up though.
How long did you have the borked S3 for?
I 2nd the bad carrier coverage notion. Just as a test, I put my phone into airplane mode while watching a video. I watched the same video while out of airplane mode. The battery drained faster while on the carrier's network than not. I noticed the signal meter was at 3 bars before I played the video.

I haven't tried that... though most of the time my phone's running cool...
Better Through Time
I decided to instal CM10 on my phone and it really did help.
I just got home from school/finished most of my day and here's the update:
63% left
9h 45m 29s on battery
1h 21m 33s screen on time
This makes me feel so much better considering that I actually used the device more today than ever before.
(HD YouTube videos, streamed Spotify, lots of internet browsing, more calls/texts.)
Even with the added usage CM10 seemed to have improved my battery life by a lot!
Not sure if I can totally attribute it to CM10 or just more charge cycles, but everything seems to be working better for me.
Thanks for all of the help!
The phone still runs hot sometimes but it has decreased over the last couple of days.
I have noticed on my phone that since installing Liquid Smooth rom has resulted in much better battery life than on the stock rom. However, ever since I have owned the phone, if i have the screen on for more than 10 minutes or so the screen gets really warm right above the home button. Anybody else experiencing this?

Same problem. I just assume that's where the processor is? It doesn't bother me. Its quite funny because the top of my screen is cold. And it doesn't get hot when I'm using it for browsing, texting, the usual. Not unless I play a game.

I'm assuming that Samsung's stock TouchWiz isn't as optimized as the ROMs that the devs make on here.
Which is a definite plus to having a device that has a strong community of developers behind it.
That happens to me as well. I have kind of gotten used to it. Just slip on a case so when you hold it your hand doesn't get sweaty and you should be fine. I would assume that's where the processor lives, but I am not too certain.
