There's not a single thread out there that has helped me with my damn battery life that I've been able to find. I'm sick of hearing, "did you search first?" Yes, I searched first. I didn't find anything that helped, that's why I made a new thread.
Anyways, I've tried apps, widgets, calibrating, deleting batterystats.bin, flashing different roms, kernels, modems, and even a new battery. Not a single thing has made my phone last through the day, and it's getting to the point where I'm about to flash back to stock, and forget about it. I need to be able to use it when I need it, not put it back in my pocket because I'm afraid of draining the battery. Honestly I'm not sure if the battery issue is rom related, so If that doesn't work, I may just get a different phone. I need to not have to charge my phone every 6 hours. Does anyone have any idea how to improve battery life on this freakin' thing? 6-7 hours on light usage is not enough. To put it in to perspective, I get 10-15% battery drain in STANDBY per hour. Serendipity 6.4 was a little better than 7, but not much. still within that 6-7 hour range. Is there anything else I can try? Anything at all? I went from 7 back to 6.4 because I thought Android System was draining my battery, but it didn't really do anything. I'm open to everything at this point. Voodoo, cult magic, anything.
Edit: reading through my message, I wanted to clarify that I am very grateful for your help, I hope I didn't imply otherwise.
Serendipity 6.4
Baseband version I9000UGJK4

I don't know what that is heh
Have you tried Juicedefender? It's helped me immensely. Other than that, I could suggest getting an extended battery, if you're willing to cope with a lumpy cappy. I'm too noob to know how to fix this problem other than by using the brute force route, but it's worth a shot.

Well, battery usage shows just about nothing... I was using 6.4 but after it did nothing for my battery life, I went back to 7. Now the android system thing is back but I'm getting the same battery life.
Here's what it shows under battery usage for today:
Display 29%
Android System 25%
Android OS 10%
Google Services 7%
Cell Standby 6%
Fancy Widget 4%
Handcent SMS 3%
Battery Graph 2%
Phone Idle 2%
JuiceDefender 2%
Dialer 1%
and that's it.
if you start seeing android system and android os that high, shut down, yank battery and let it sit for a few minutes. then replace and start up. should help with that and improve battery life.

The problem is, I'd be doing that every 15 minutes. It boots up already taking up more than 10%. I just did exactly what you said, and it booted at 23% for system and 3% for os.

flashed cyanogenmod 7, and turned off mobile data and wifi and just left it on idle for like 2 hours after resetting the batterystats.bin and rebooting... i uninstalled juicedefender because it was actually USING batter... *shrug* and left it that way... well, I opened battery left and looked at it and saw that it would die at like 5am... well, i was disappointed... until I noticed it was 5am, 26 hours from now. That's notibly longer than any battery left stat I've seen since I started noting battery issues... So... Yeah. I think I'll stick with CM7 for a while hehe. After I get an idle benchmark, I'll start using it more. Thank you for your help.
do you live in a poor 3g area?
the problem could be that the phone is constantly looking for a good connection and cant find one, causing massive battery drain

I was just going to say the same thing. If your phone is constantly trying to establish a connection, is alway searching, it's using up lots of juice. Same if you've got gps enable or wifi on. If it's looking, it's active and battery's being used.
Another thing you can try which helped me is to call art and get another free battery if your phone is still under warranty. The new battery I have seems to last almost twice as long as my old one. Of course make sure that the android os isn't eating the battery and mine last a while. Just a suggestion.

Since installing a new ROM, last night, my INCS has been running very hot and seems to be caning the battery.
I charged over night, unplugged it at about 7am and it is is dead already. I haven't been using much more than usual, and so it is concerning me slightly.
I was wondering if anyone could help me find out what is causing the issue and ways to resolve it?
Cheers!

Check the task manager to see what processes you have running. You can also check the battery settings and one of the screens will show what has been using the battery.
Have you tried rebooting the phone?
Thanks for the tips.
Nothing out of the ordinary seems to be running in the background, and most of the battery drain is the screen which isn't too much of a surprise. I don't have many apps installed yet.
Would it be worth installing a cpu monitor to check the cpu speeds, in case it is running too high?
On the stock ROM it would last a good 12 hours with moderate usage and a lot of apps installed and running.
You can try setcpu or whatever CPU utility depending on your rom.
You can set offscreen to a lower speed like 600mhz or so. See if that helps you out.

What are the ideal cpu speeds for the INCS?
I dunno what Rom you're using. But I would recommend you to use all the battery until it shuts down. Charge it to 100% then use a battery calibrater

I'm using Virtuous Quattro RC3 (btw, love it!)
I've charged to 100% and I'll leave it on tonight and see what happens.
Right, I don't know what's changed, if anything, but I left the phone on over night to discharge and it is still at 55% and very cool to the touch.
I guess it just sorted itself out!
Cheers for the help though.

I think that is why many of us expect a huge battery improvement after updating to JB ,perhaps the newer system wont be so power hungry.
these screenshots are fun and all but they are totaly irrelevant.
hoe much USE time are people gettng is whats interesting.
so screen on time.
as the goal is no drain with screen off and as long as possible screen on time (this is when you use apps and so on).
my phone can be on for 2 days and still hve 95% juice left but thats kinda irrelevant if i dont touch it.
when i use it non stop my use time averages on 4 hours and 15 minutes so far.
all the people having problems with battery drain must have either bad apps installed of verry poor wifi/3g connections.
as in a good serup with no bad apps and good signal wifi should not drain battery at all if your not using it.
i would so like all people with issue to lend me there phones for 3 days to see if in my stable envourement they have the same issues.
im fairly sure that all these problems are signal and user related and that it has nothing to do with the hardware.
My phone would only give me 2 hours max if the mobile data is on with sync off facebook sync set to 1 hour and hotmail sync set to 1 hours. But if wifi is on throughout the day i would get around 3 hours 15 min average with sync on hotmail set to push and facebook sync set to 1 hour. The battery is really poor as i only use it generally for txting whatsapp and just a bit browsing thats all nothing else. When i watch videos my phone consumes less battery, than normal usage which i do everyday. The highest screen time i have ever got was 4 hours 15 mins thatd because i watched a video for almost like 3 hours thats why. But the battery is still really poor

My android system also consumes a lot of power, its always on top no matter what. I am running on V_10H I disabled some stock apps using titanium backup and used fast demorcacy but the only difference I could see was android wakeups had been much lower thats all and so less power consumption when phone on standby thats all.

this is totally relevant information for regular users.
many people complain about battery drain and that a custom rom is the cause or custom kernel when its available, but what shows that it is not, is when you can place your handheld mobile or tablet alone with wifi set to instant off and you got 3g disabled and it lives for days without loss of battery, you know that it is stable.
when you suddenly lose battery in hours and previous tests showed it was lasting days, you can be sure you got battery infected apps trying to activate your cpu all the time.
i'd like to buy this phone but i'm a bit afaid of the battery drain. people who says it last 2 days with normal use other says that with gaming and browsing lasts 10-15h but a lot says that the battery lasts just 6 h with normal use... can someone who owns this phone and he use it with a middle-intense use (texting,browsing,gaming some time) tell me how much lasts the battery please??

Well, my usage pattern is kinda light, but still...
- took it off the charger at 7:15 am
- 3g data permanently on while I'm not at home (from 7:20 til 18:00 or 19:00)
- wifi on when I'm at home (during the night too, I never switch the phone off)
- sync always on (gmail, whatsapp)
- received a couple short phone calls, let's say 5-6 mins
- received a bunch of emails, say about 15 or something
- some messaging (on whatsapp and gtalk, I don't use sms)
- some facebook, let's say 15 minutes (through mobile website 'cause FB app sucks big time, always had and most probably always will)
- some net browsing looking for a few stuff, let's say 5-10 minutes
- checked a couple forums on tapatalk a couple times
- updated 3 or 4 apps on wifi
- downloaded a 50mb game on wifi and played it for like 10-15 minutes
- ebook reading on moon+ for 1 hour and 30 minutes (maybe even longer, didn't check the exact time)
I connected it to the charger when it reached 12% battery at about midnight THE NEXT DAY (yes, that is around 41 hours without recharging it)
Overall, I can say I'm satisfied, at least for my standard usage...
- Stock v10h firmware, no root (yet).
- Nova launcher since 5 minutes after buying it
- I usually keep brightness quite low unless I'm out in the open under the sun, good thing about this phone's screen is that it's usually very well visible even with only a 20% brightness. If I need to use it in full sunlight, I conveniently placed a full brightness widget on my homescreen, and then back to 20% with one click when I'm done. No autobrightness 'cause I don't like much how it's set to work on this phone (was kinda better on my old i9000, but oh well, 1 click widget and I'm good to go, no sweat)
- Disabled 3 or 4 stock apps (through app settings, no titanium or other stuff)
I noticed that battery usage was kinda higher before disabling those stock apps, I guess one of them was a powermonster of sorts (I suspect the meteo one, but I'm not sure)
- No facebook notifications of course, not for battery-related reasons but just 'cause I simply hate them... but I guess that's nice on the battery too
Hi
I've been lurking these forums looking for this but haven't found anything quite like this. The P880 prides itself on great standby battery life but mine is draining more than my previous Motorola RAZR (not the maxx). It never lasts more than about 14-15 hours and that is when i do almost nothing. One, two calls a few messages with no wifi and data off. I have factory reset the phone a few times and whiped the cache. I've tried not installing any software when done and fully charging but still it drains. I'm on v10f but this was a problem before I updated as well.
My only thought is that the battery is flawed, but I don't want to wait 2 weeks for it in repairs if it isn't (the service here is slow and customer support is weak when it comes to this, here in Iceland)
I took screenshots of the drainage. 90% of that is me not using the phone at all. Is this normal? Should I ask for a new battery? The phone is about 3 weeks old btw.

What version are you on? 10f has seen lot of improvement in battery life. I dont have to use SetCPU anymore to get better battery and let it run on max 1.5ghz and still seeing very good battery life, despite heavy use.
Yeah I'm on 10f as well. I was wondering if maybe flashing the phone and try to reset it totally would help but I don't know if that'd be any different than just factory resetting?

I'm going to charge him to 100% and leave him with nothing on all night and see how he handles it. What would normally happen? How much percent-drop would the battery have on an 7-8hour timespan?
Went to sleep with the phone at 94% and woke up with 69%. Everything was off. Sync, mobile data, wifi, backround data, location, gps, nfc, I even set it to 2g networks only. Now it says that the "phone" took 69% of that? I'm flabbergasted.

Same here man but didn't diseabled auto sync and broadcoast cell yet so I'm curious if I go sleep and wake up how much juice it took from my 4xHD. Something is sucking out the juice out of our phones.
The only thing that update did change with me is the heath it didn't get as hot as before but my battery is still eating a lot even when is standby.
Hey, I don't no if your phone is rooted or not?
Try deleting superuser, it helped my battery life. And also you should charge your phone more than 100% , that helped too for me.

Try to do a factory reset, the update didn't help me until I did a factory reset. Now my 4X HD only looses about 1-2% over night vid auto sync, before factory reset I lost about 30-40%.

I use GO Power Master to auto switch to Alarm mode (only alarm, brightness 30%), and the phone eat less than 1% of battery for 6 hours. (firmware V10f)
I cannot see the attached images (don't know why) but I think you should check how long your phone is Awake, Screen On, Wifi and GPS On... then see which apps are cause the drainage.
Also, give the battery more recharge cycles. The battery life on first 2 cycles was catastrophic - for example it lost 4% just by rebooting, but after few days it stabilized to my ordinary each 2nd day charging cycle when turned off in the night. The biggest battery eater seems to be for me display brightness.
Batterylife with 10F is pretty good. Over night I dont lose any battery (data off) and during the day with autosync on only ~2 percent per hour. This is even better than the Samsung Galaxy S2 which I previously used. I did set CPU max speed to 1,1GHz with SetCPU.

No power save. That gave me less battery. As far as it goes you need to see what apps are killing ur phone. Screen time on is key cause it means you are using ur phone. So you need to start with better battery stats and see what's going on.

Find out what app is waking yoour phone. That is what is most likely the problem . 99% of the time its an app or user error . Wakelock detector . Or cpu spy to see if your phone is deep sleeping or not .
Hope that helps cause I highly doubt your phone is deep sleeping with drain like that . You need to find what app is keeping it awake

Also see how much you are draining per hour while the device screen is off . If you are using it for 5 or 6 hours with the screen on then that isnt bad . With moderate use I charge my battery every other day.
Every other day? I can barely get by one day.
I did a complete reset, and the battery life got better. I'm at 45% with 3hours screen time so i don't know waht the problem was..
and how would you found out what is waking up my phone?
Thank so much for the replies!
I didn't have great battery life either.. But I see that Google play music runs in the backround constantly, I end up closing it like ten times a day.. I froze that app and it made a HUGE difference for me at least.. If you don't use it give it a try
