I previously made a thread regarding low battery life.
After a week of use and more testing, here's what I gathered.
(Note: I have GPS, Bluetooth, Wifi always disabled, brightness lowest)
My phone will completely drain out in 6-7 hours.
I found the culprit: Cell Standby
1.) Cell Standby always uses the most battery, often 60%+.
2.) Phone Idle often follows with 30%+.
So, to verify my theory that the screen isn't the issue, I turned on airplane mode.
I proceeded to watch a 1 hour comedy, and battery life dropped from 60% to 50%.
This is lower battery usage than if it were sleeping with cellphone on.
I then noticed that my signal hasn't been good (provider sucks, no choice, all of em here sucks).
So, I placed my phone on, but asleep inside a locker for 2 hours (no signal).
When I took it out, it was very warm at 40+ C and battery life dropped about 20-30% per hour.
I've tried turning 3G off, turning always-connected off or downgrading 2g.
The result has always been the same. It still sucks bigtime.
It seems like Nexus One also has this problem, anyone notice similar problems?
I've googled and been told that this is "normal", because the phone increases power to secure a signal.
However, I've clearly owned phones and placed them in signal-less lockers prior to this, and trust me when I say most of them drop 5% per hour max.
20-30% per hour is horrible, and clearly the phone is overpowering its components.
There are some certain Radios you can flash to improve how your phone uses power to pick up a signal, Requires root access tho.
Can you please point me to those radios? I've already tried updating my radio to latest.
My phone is already rooted.
My battery is a joke and I have tried many different things. I always have to charge it by around 3pm everyday during week as It will almost die on way home.
I take it of charge at 7.30am by 9.30 it could be down to 86% and then it judt continues to drop by 3 It can be between 60 and 50% if lucky, by time i'm tenmins from my house I get 15% and warnings.
I use basically for txt, some net usage and sometimes playing a game 10 - 20 mins tops and or read ten mins of books.
I have all updates off only manual and screen down low etc - doing my head in!

Im facing the same level of battery drain, but i have 3G turned on constantly with updates from facebook every hour twitter updates every 15 mins and mail app every 30 mins. And i mostly use my phone for music and SMS with occasional browsing.

Strange, I always have 3g on, and still play a lot with my hero (games and such)
Still it survives about 36 hours on 1 battery load. Without 3g it holds out for 72 hours.
Post #1 on the thread below seems to have a working solution (re-interpreted below)
It seems to be something to do with the battery stats and charging via usb through PC instead of via the mains.
You have to clear your battery data when your phone has really really low battery (this is probably the MOST IMPORTANT step) (you can do this through recovery mode in amonRa). Once the battery data is clear, switch back on (before plugging in) and drain the battery so that your phone switches off by itself (playing music loud and switching wifi, data connect etc, etc is suggested in the thread).
Once battery has died, plug in your phone WHILE it is STILL OFF, then when the battery shows green (will probably take longer to charge because this time it is getting a full charge), UNPLUG BEFORE you switch it on. and you should notice the significant difference. - Oh yeah make sure you switch off all those data connections and wifi and all those other things that you used to drain the battery - unless you use some of them of course
EXTRA TIP given on the thread: TIP!! Remeber when changing and flashing new roms to unplug the phone from charge *(i.e. unplug from your PC) (edit Bad4ss) * after you boot!
TO answer LennyUK's Q below ( and so that the next page doesn't start to quickly before this suggestion is read ) I think why it is suggested for the first boot after this process to be done while off is because it is already off because of the drain AND because it will get a clean full charge up for the first time after a battery data wipe. Because while it is on it will be depleting the battery even if it is in a small way - after that you can do it whichever way you want *nudge-nudge-wink-wink-say-no-more*

I don't see why the same thing cannot be achieved by charging with the phone on, just as long as you don't change between phone being on or off during the charge i.e. if you start charging with the phone on leave it like that the whole time and visa versa

Can you do this on non rooted phone? How do I get into recovery mode?
I think the analysis is flawed. I also think the stats information doesn't tell you everything. For example, yesterday I had 60% cell standby, 20% WiFi, 20% phone idle. Consumption was 45% in 24 hours.
Previous to yesterday, I had high battery consumption. So yesterday was a breakthrough but YMMV. I removed the PCSCII and the Mail app (I don't sync with Exchange and I don't sync with a PC as such - I don't run Windows). I also disabled auto task killer. I rebooted without being connected via USB to power or to PC. Suddenly power consumption became similar to Modaco ROMs.
Last night, I also disabled the setCPU application and rebooted. 6% battery consumption in 9 hours. 34% cell standby, 33% WiFi, 33% phone idle. Consumption was 45% in 24 hours.
how have you improved battery usage, ive tried resetting battery stats, draining battery, fully charging, using kimera 1.5 and with no wifi no bluetooth, not using phone in few hours it was down to 63% and in 10mins had dropped to 59%
i had similar battery problems but today i changed radio versions into a different one, now i get almost full signal all the time and battery usage is geatly increased (went down 2% in 4 hours as compared to 10%/hour)
so i suggest finding a radio that give you good reception

Which one did you use?
im on tmobile uk, changes radio from
63.18.55.06JU_6.35.09.26 to
63.18.55.06JU_6.35.08.29
made alot of diference
you should ty out diferent radios and find one that gives the best reception, it will be different for different providers and countries
also i did this...
http://forum.xda-developers.com/showthread.php?t=647460
i unplugged my phone from the charger after doing this at 6am, it had 100% charge
its now10:45 pm, i have 44%charge left...its crazy
before i used to run out of juice around 10 hours after i charged my phone, its not been almost 17 hous and i got 45% left
i seriously suggest doing this

I will use that radio too seeing as I too am on T-Mobile in the UK. When you say to use the link and suggest doing it, I take it you mean the "get to 10% -> get to recovery mode -> wipe battery info -> reboot and drain battery 'til off -> charge while off and the take off charger once charged and switch on..
'cos I tried that and still having problems - am using the new Villain 4.0 beta2, so maybe the radio change in combination to this is what will work - I'll try it tonight when I get home.
immya : many thanks i now hove phone back
flashed radio 63.18.55.06_6.35.05.31
and lost 1% over night
previously on LOST
radio 63.18.55.06JU_6.35.09.26 lost 56% overnight
perhaps issue with 2.1 roms is the latest radio and not latest kernal
BTW using sensehero at moment as was trying 1.5 roms to get better battery, and that didnt work.
some one maybe sticky this info , if anymore find it a saviour. will report back after work, mayeven be able to use data syncing again
Hi,
X10 Mini Pro here - the battery only lasts about 16 hours without ANY activity on the phone (only 2G radio on, no calls, no using the display, nothing!). If I check partial wake usage I see Messaging is keeping the phone up the whole time (15 hours out of 16 hours). How do I solve this?
With normal use (calls/browsing/apps etc) it lasts less than 8 hours!
did u find solution pls tell me also same problem
for messaging go to cyanogenmod settings-preformance settings and disable lock messaging app in memory.
then set wifi to never sleep.
my battery life is arond 36 hour (ni data conection only if i recive mms, wifi around 1 hour per day, around 10 calls per day, around 30 sms per day, brightness around 65%,and auto kill apps)
I'm running stock latest 2.1. Messaging today is 8 hours lock wake out of 9 hours. Battery at 50% with NO use!
Did a backup, reinstalled everything through SEUS, then restored. Now back to normal. Just back from 8 hours of work and battery is only down 20%.
my phone gives a backup of more than 2 days......here is how...
for both stock and custom rom.....nd if u have root access....then u shud use SetCpu and Auto killer memory optimiser...set both of them to ondemand and optimum resp. and charge ur phone only when its <10% and avoid disconnecting it until its completely charged....this would improve ur battery backup and lso battery life.....significantly..see if dat works for u guys...
If you have flashed a rom, then you must fully charge the battery, immediately Wipe Battery Stats, then let it full drain and battery would be almost fixed. After full drain, fully charge it. When it says completed pull out battery and put it back and charge. You'll notice that battery level is ~84% even if you fully charge before. After full charge, pull battery out and do the same as mentioned before until you charge phone and battery level is always 100% or 99%.
That would make battery last longer.
And... If you have CM, undervolting saves very muuuuuuuuuuch battery and you should underclock when you are planning not to use phone for some hours... Of course freeing memory is essential, because you kill the apps which use your phone, as a result your battery too!
Good luck! ;-)

Nice im going to try some of the suggestions above
my battery also drains pretty fast!
I have the stock 4.5.9 gingerbread update on my AT&T ATRIX. However I am observing a terrible battery life. There are too many solutions in the forum to follow. Can someone direct me to the appropriate one? I am rooted and unlocked. I used the unlocked 4.5.9 sbf for upgrading from from Froyo to gingerbread 2.3.4
Sent from my MB860 using XDA App
there;s a lot of solutions because poor battery life can be cause by many things, you have to find out what is draining your battery. try calibrating first let it drain until your phone turns off and then if you have cwm install then wipe batterystats and then a full uninterrupted charge
Try setting profiles in SetCPU and freezing apps with TitaniumBackup. Theres a topic for each of these two solutions.
battery stats 6h 3m 29s on battery (now left with 10% of battery)
Display 49%
Phone Idle 22%
Cell standby 6%
Android system 5%
Launcherpro 3%
xda 3%
Android OS 3%
this is just terrible .. i never had such battery life with Froyo. i dont understand what might be the problem. Meanwhile i will try to calibrate my battery.

Calibrate your battery.
Then freeze your bloat.
Problem solved.
dont forget you might also being playing with your phone a lot more trying to see all the new stuff in the update. Thus causing more battery drain.

There are some strange things happening with the battery. I let my battery discharge completely to the point where phone shuts down. Then I plugged in to charger, waited for 2-3 minutes so that I can start the phone. Started the phone and saw 50% battery. Don't know what's going on.
I was told by an admin from another site that most of the battery programs do not work with ova ginbread. You go to settings/about/status and observe the battery. I do no I was also getting flaky results with 2 of the battery programs.

That's a GB bug... there's a battery fix in the development section to flash which deals with the reboot battery jumping. (turn off phone at 50%, turn on phone and it says 70%)
I am having problems with my Atrix too. With my usage, I used to be able to get almost 3 days of battery life. Now it hardly lasts a day. I have checked pretty much all settings (sync, sleep) and all seems fine as far as I'm concerned. So I am having hard time trying to find what is causing this. The only suspect I have right now is wifi. I don't think wifi is sleeping even though I've selected "When screen turns off" in the sleep policy.
Hi there.
this morning (12 o'clock) i wanted to use my phone and only red LED's light up when i pressed Power button! I'm pretty sure i had more than 40% Battery left when i went to bed at 01 AM.
Plugged in my phone and started it. Surprising thing was Battery at 1% and when i looked at battery stats it droped from ca 40% to 0% in an instant!
Might be time for Battery Calibration ?
okay...... just had the same problem again!
was undervolting the phone.... 750mv for 128mhz, and it crashed! had 80% Battery before. and 1% after crash, and slowly went upwards till 6%, then i rebooted.

Dear, the problem is that u must have installed a new ROM or an update without wiping your battery stats. That means ur battery infact is not showing the correct %. Infact I guess now its completely out of charge. Just reboot into recovery, wipe battery stats and then dont reboot the phone. Just take off ur battery.
Now plug in ur charger and put the battery in.
This will take the phone into offline charging. See the grey big battery icon. How much its showing ?
Offline charging actually will show u the real battery %
Charge it offline for like 20 to 30 mins and now switch on your phone.
It should be ok.
Let me know if its fixed.
Good luck

Also... I guess there is no need to undervolt your phone for good battery back up.
If you are using Wolf 4.04 with the stock kernel, it itself will give you over a day battery...
just what I'm doing now...
Try calibrate it first mate

Having similar problem here.
More details:
- drops from ~40% to ~5%
- phone shuts down and after boot, battery is back at ~40%.
- it happens only when the phone is in deepsleep, if it crosses 40% when CPU is active, it's fine, but after around 6-10 hrs in DS it drops to <5% and shuts down
- after "instant drop shutdown", battery life decreases (discharging around 25% faster), also fast drop from 100% to ~90%, when it gets below 90% the drain is "back on track"
Phone specs:
> X10i UK
> Bootloader unlocked
> ROM(s): same issue on ZMOD v3, VMOD v5/v6, FXP046, testing on Wolf's Stock Mod,
> Kernel(s): DoomLord's v1.3 FS/v1.4 FS, FXP Kernel,
> Original SE Battery,
> Phone bought at end of June 2010,

Here download and install this and your problems should go away when you do it right. https://play.google.com/store/apps/details?id=com.nema.batterycalibration
Sent from my X10i using xda app-developers app
Had the same problem and it was the battery dying replace the battery with an exact same battery no higher or less mAh rating same mAh rating and follow instructions that come with new battery carefully then carry out battery calibration manually with wiping stats yourself and fully charging and discharging a few times to get proper battery life. I did all this and now I'm back to how it was when I first bought phone but my case was worse as mine would drop from 86% to 0% soon as it hit 86% that was it could use phone so get a new battery there cheap enough

Hi guys. I'm running on CheckROM revoHD4 and while sometimes I lose 10% of battery overnight today I dropped 30% in 3.5 hours doing absolutely nothing with screen off and not a huge ammount of apps running on the background. And its not the first time I notice inconsistent discharge. When I installed this ROM battery would last for 20h/3h screen/3h voicecalls. now sometimed it doesn't even last half of that. Any ideas?
You should check the battery info via Settings > About Phone > Battery Stats to see if you find a proccess that is huging the battery.
Also you could download Better Battery Stats from the Market and find which proccess are the ones doing the more Wake Locks and how much time they have done it. You could find for example an app thats been doing that for hours and that could be the cause of the battery drain.
