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
Kernel Version 2.6.32.9

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.

Yeah, with gingerbread roms I've heard it's fairly common for you to have high usage from android system. Check that?

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.

Hello all,
I have seen reports that because the source code for the captivate has not been fully released, some of the processes cannot be put to sleep when they are not being used, and therefore causes bad battery life. I am just about to flash CM 7.1 and am curious to know how the battery life is on the captivate.
All info is greatly appreciated!
LWt mw know what you find out! Just flashed it and my battery goes quicker than my bank account. Please let me know what I can do to help this I like the rom

Jaye,
This happens frequently when flashing a new ROM, you should try wiping the battery stats or giving the ROM a few days to calibrate with the battery.

You should try a custom kernel like glitch or Neo to see if that will help. I get awesome battery life in miui which is bases of cm7. I find that neo gives me the best battery life.

Also, some people must be getting solid battery life, or CM7 wouldn't be as popular as it is. Or is this a known thing with CM7?

Yeah that's pretty awful. Try doing a battery calibration to see if that helps. It should never go that quick (unless you're playing some serious games). I've never really had great battery life with cm7/miui I've had the best battery life with all the recent samsung gingerbread leaks. I think those are better than cm7. But that's my opinion.
I am in CM7.1 since Sunday. I had very awful battery in start. So I did battery calibration, manually. So I got very decent battery on wifi. But at work I use att data so again my battery life was horrible. But I am seeing improvement since I am using this app called green power to manage my data. Try that.

If you get good battery on WiFi but not with mobile data, try a different modem. Not only are some modems inherently better on battery, but if you find one that gives you a better signal you should see improvements in battery life as well.
Flashing the Glitch kernel seems to have improved my battery life.

Hi, Can you point me to a post that (a) has the Neo Kernel and (b) explains how to flash it on MIUI? I've had MIUI for a couple of months now and battery is to as good as expected. Would love to try to use another Kernel but I sincerely don't know how to do it.
Thanks in advance,

Solid Battery Life w/ Stock Kernel
Hey Everyone,
Juts came to report that I have been getting great battery life using the stock kernel. I would say it is a little better than Serendipty VII Build 2 which I came from. Only issue, and this is something I know is inherently wrong with Cyanogenmod on the Captivate, when you fully charge the device, it only shows it is charged to 98%.
Other than that, all good!

Have you seen an improvement in this regards, I am having the same issues, the WiFi is draining my battery slower then my data is.
I have also done the battery calibration and it doesn't seem AS bad... still doesn't appear to be great though.
I am just coming back to this ROM after experiencing battery issues even though Glitch helped a little. I decided to try and tweak some more this go round.
I am experiencing much better results this time. Here are settings and other tweaks or modifications I have in place.
-sync is turned off
-using Launcher Pro with very few widgets (just 3GWatchdog and Power Control)
-auto brightness turn off manually adjust according to need
-gps, wifi, BT, and data turned off when not in use
-wifi notification and location detect off
-installed jk4 modem (may get better results with different modem depending on your area)
-installed Glitch v12 high leakage
-the biggest factor this time I think is UVing on the Freqs that are used while phone sleeps >>>>>100/200mhz (set for the lowest UV setting possible on these that do not result in a sleep death or reboot when phone is put to sleep)
can anybody who used all three of the roms comment on the battery life of these ROMS? how do they compare against each other?

im not one to say I have used all 3, ive only used CM7. it was good. actually even MIUI is good but u gotta know how to find your wakelocks with betterbatterystats. that way you can optimize battery life regardless of whatever rom you're on.
I could go 1-2 days on my MIUI currently FR rom, moderate usage, all my syncs are off, i manually refresh for notifications.

What do you mean "but u gotta know how to find your wakelocks with better batterystats" ? I usually dont have anything running in the background...
I have used CM 7, all MIUI, Lewa, and Mokee, and Ice BlacK too
In my view
1. CM7 have better battery life (but as I use to play 3 D games I won't prefer)
2. Second is Galnet MIUI, built by elol, decent battery life with good performance.
3. Third is Mokee, It is the best ROM for gamer and for others too who don't use to play game. It almost serve me for whole day with games, music and all mail, FB, Linkedin sync on for 24 hrs.
For me best choice is "Bumblebee" it's really a stable ROM and give's really great battery life, Best in which i have used.
In term's of Gaming this ROM is really great, it give's games extra smoothness to Game's by increasing FPS with help of it's new GPU derive.
This all make this ROM as my daily use ROM.

google xda betterbatterystats. download the app and follow the thread, those are uber battery sensitive people in the community.
so you manually sync all your apps as well? even calendar? and leave gtalk signed out?
wakelocks are what keeps the phone away from entering deep sleep. from the betterbatterystats app, if u see ur device entering 96% and above Deep Sleep after a night's full charge and allowed to idle, then good job, no matter what rom ur running u should be doing it right.
wakelocks are what cause a battery drain even when your phone is off idle while u sleep. it isnt only about background apps.
Yes,,I was use betterbatterystats,,I have managed all wakelocks and partial too,,it's give me battery life more time
But battery use info from setting doesn't change,,still give me "Android System" for highest % deal,,

post your dump here. and also at the BBS thread where u got the app.
so unless you are getting 96% and above deep sleep, id say you have not completely managed your wakelocks yet. also what are your governor and i/o scheduler settings? OC'ed at? do you have a screen off profile to lower clock speed when screen off?
battery use info may show that, but most important is u charge your phone to full, let it discharge while u sleep and wake up next day, OBTAIN 96% DEEP SLEEP OR HIGHER. figure out what are the wakelocks in BBS. if BBS is managed correctly, even if your android system is using highest %, no big deal, more importantly your battery isn't draining like mad.

Hello.
I was a PA 1.6 and PA 2.X user since last week, when I decided to install stock ROM to check if battery life would improve.
I've been trying different ROMs and realized that battery performance was worst,so I decided to check stock ROM to see if I could get any improvents in battery life.
Yesterday I installed SGN_XX_OXA_KJ1_FACTORYFS stock ROM, but during the night I lost 50% of the battery (I didn't turn Flight Mode on) and now it's draining at 3.5%-5% battery per hour.
I reinstalled the RADIO, but I cannot understand how stock ROM + RADIO can have this much of battery drainage.
Any ideas on what can be happening and how can I solve this?
The only thing left is to format all SD partitions and pray. :laugh:
try slim bean with sync off and just 3g
and check ur battery
if it presists then try flashing xxlrk or xxlr1 modem

Can someone gv me more tips and trick for battery life, ive customize my device at minimum, but its still drain fastly. Still dont know why.. Here what i did.
.brightness lowest
.data, wifi, blutooth, nfc turned off if not used
.extended battery on
.i dont play games.
Cpu spy showing deep sleep well when i didnt touch my device, but android system is showing the highest in battery life. Im abit confius about that. Shouldnt screen is the highest? Hmm.
Sent from my LT25i using xda app-developers app
Here is my ss. Why the hell android system is the higher? Ive used many android device before, seems this is not normal. Deep sleep is going well according to cpu spy.
battery life is really relative
it varies on users to users
it depends on many things:
- brightness display settings, auto vs manual
- apps installed, some are consistently running on the background
- data connection, this is the biggest drainer, depending on your area, you may get strong or weak signal(weak means your phone will tend to consistently trying to look for better connection from the network resulting to more drain in battery)
- etc., etc.
bottomline, don't worry about it too much unless the drain is really really horrible
personally, my TX is horrible in 3G but that is expected
Thank you for replying, may u check my screen shot, i just upload it. and please tell me is this also happen to ur device? normal/not normal?
I once had this problem and solved it by wiping cache and dalvik cache. System isn't supposed to use most resources on the phone
But even with system using that much battery you don't have a bad battery life.
I usually don't end up with 50% battery after 12 hours (usually I'm already drained by then )
