Now I am running stock KI8 from intratech and CF root, but I am not satisfied by my battery, what you recomend to try? I think maybe try SiyahKernel or you can suggest a rom. Looking for any suggestions
Read battery posts use Better Batttry Stats.
Turn off what's draining the battery. Donk keep flashing roms.

If you have done using your phone and will let it lie idle for a while always go to task manager and clean memory
It helps
Just freeze every single thing you dont need through titanium backup.
Worked for me pretty well.
Just be careful with the system apk's, some of those are nessecary to run.
It seems the stock ROM you're on has one of the best battery life. If you're just concerned with just battery life I highly suggest you to stay with your stock ROM and kernel (cf root). The problem might be related to phone usage, maybe too many apps that sync very frequently (facebook, twitter maybe?), in that case you should try to sync them manually.
Anyway if you want to try siyah kernel, I've read that many people experienced good battery life. For me the stock cf root gave me better battery life than siyah 1.7.7 and 1.7.8. Anyway, trying won't do you any bad.
hey
after a night I my battery drop 2%, i think it is to much. Here is some screens maybe you could advise something for my?
Hi. There are a lot of battery threads - a lot!, but after using search I found nothing relating to this problem.
My phone was fine up until a week ago or so. I'm on stock 2.3.5 after upgrading from VillainRom (which was great, but I just wanted stock back).
I've been back on stock since 2.3.5 released and everything was great. I froze/stopped the bloatware ect..
But the last week or so my battery drains 45-50% a night. I have wifi off and also the data network is off. I don't know what could be doing this.
Could someone help trouble shoot this please? As I said, it was perfect before, I don't think I've changed anything, wifi and data are off overnight, all apps closed.
Thanks very much.
EDIT - So I bought two new batteries and I still have the same problem. I've even went back to VillainRom 3.0
Now here's the kicker, after putting my phone on charge in the morning, after two minutes it's up to 46%. So whatever is happening it's not the battery draining, it's a software bug or a hardware bug or something.
Has anyone heard of this? And what's the best way to go about this?
Also, why would this only happen overnight and not during the day?
EDIT 2
I have attached 3 screenshots of my battery stats.

Better Battery Stats should be of help.
You'll be interested in Partial Wakelocks, and possibly Kernel Wakelocks. If you're unsure of anything post in that thread and someone should be able to point you to a solution.

Thanks. I've been trying that since you suggested it. It hasn't helped. I'm thinking it's a software problem, so I'm going to start fresh.
Thanks for the suggestion though.
Maybe you can try to do a factory reset and start again from the beginning (gmail account, install apps, etc...)

Yeah, that's what I'm just about to do. I'm also reading about Villain 3.0, might give that a go while I'm at it.
So I bought two new batteries and I still have the same problem. I've even went back to VillainRom 3.0

Try recalibrating your battery. Drain it completely to 0 and charge fully. Then wipe the battery. Status.

I did that with my last battery, which is what prompted me to buy new ones. I also wiped the battery stats again when I installed villainrom.

DON'T DO THIS.
There batteries are not meant to drain to 0%. It could damage your batterie.
If you already wiped your batterie stats with this batterie, just use your phone and charge it when it's almost empty. Repeat this a few times. It is possible that your batterie needs to settle in and that your problem is solved in a few days.
If not, try flashing an other rom. Make sure you wipe everything (except batterie stats, because you already had).
Yep do not drain it completely.
I would recommed to calbirate your battery. It seems that your battery stats are somehow off.
Use this guide here:
http://forum.xda-developers.com/showthread.php?t=1312273
If it does not helpt do it againg and go through a few charge cycles.
If the problem still persits I would consider a factory reset.
download battery calibration from market and follow instruction.
Thanks for the replys, but none of this has helped. What else could it be?
Imho the Battery will never drains to zero, the phone will turn off before, so let your phone on until it turns off by low voltage, if you afraid ruin your battery, use the eldest, you already got 2 spare batts
I had a similare issue some weeks ago and my phone went dead 3 !! hours after the indicator reaches zero.
Maybe it helps.. (No guarentee)
Just to be sure, have you tried a different charger? perhaps yours is messed up?
BTW, i flashed 4 different ROMS in the last 2 month, and i never wiped my batterystatts .. no issue with that (for me)
Try a different kernel, based on my experience, the rom is almost nonrelevant to battery usage, the kernel makes the major difference, give Phenomenal Extreme a try, this kernel boosts your Battery for real! -> http://forum.xda-developers.com/showthread.php?t=1351191
Turn of location service and facebook
Good Luck! Feedback appreciated..
if you wipe to factory resets, add your google account, but don't add anything else, does the same thing occur?
If so, I would say it's a hardware issue, otherwise it's probably software.
I saw someone suggest using better battery stats, and you said that it didn't help, what do you mean it didn't help? It doesn't fix anything, it just lets you identify WHAT is using the battery.
My Galaxy S used to drain to 50% overnight, turns out it was the instant messaging (using MSN) that was doing it.
Like I said, try it after a clean factory reset with just our gmail account, no MSN, no Hotmail, no Yahoo, etc and no Additional Apps
or you can try speedmod's kernel ... test 13 i think is the latest ..
works a wonder to me in terms of battery performance
I can try another Kernal, but I have switched recently.
Because of this issue, the last time I switched roms and kernals I did a clean start, and I didn't restore anything, I literally started from fresh.
I'm using VillainRom 3.0
Kernal: Siyah 2.1.1
Modem: KI3
I will have another look at battery stats aswell.
I have added some screen caps of my batterys stats to The op, I'd appreciate it if you'd have a look.
Thanks again.
I won't bump this again if there are no replys, but just incase it was missed.
Sorry.

I've said this in another thread a while back and people started to jump at me, so i left it alone!!!! It doesn't actually change battery performance, just the reading accuracy!!
actually wiping battery stats is good when you first flash a rom because you'll be flashing someone else's battery stats which creates irregular measuring; therefore, you would want to wipe the stats and create your own. but to Calibrate battery over and over with it... no point really...

So is it means that when a Dev built his Rom, it will carry over his phone's current state of battery status into the new Rom and everybody who flash his rom will get his battery status? I'm confused a bit here ...
Anyone noticed that the new ICS kernel is taking up A LOT of battery life? Even on standby it's draining a lot.
Any way to fix that? Or i'll just have to live with a really crappy battery life?
welcome to the ics battery crap. You'll lose many hours of your life trying to figure this one out... essentially, there are two basic directives:
1. clean install (FR, cache, dalvik wipe)
2. wait for a few days for the calibration to happen.
there's a bunch of other suggestions as well... Oh and your screen might also run extremely hot sometimes!
Enjoy

A lot of us are getting hit by it. Sometimes the cache wipe and factory reset stuff works and sometimes it doesnt. Motorola has some new ICS builds coming down the pipe. Latest one is .215 and people who have flashed to it have seen dramatic battery improvements (back to how it was with GB).
So hang tight, help is on the way.
I've read some reports of improved battery life after Sprint ICS ota.
I've read some reports of worse.
But overall, I haven't heard much of anything.
My wife's stock ICS had horrible batteryife now. Like drops 50-60% in 3-4 hours with no use.
Don't suggest root because she doesn't want it (and it will be my problem, like now with this battery)
Any thoughts besides factory reset? And if I did factory reset, how could I restore all her data? I've never used titanium backup on non root.
Thanks y'all
My battery life got much worse after I updated, but I think I figured out most of the problem. I had added the News & Weather widget and set it to prefetch articles and the images for articles. Turning that off improved my battery life by a lot.
In case you haven't thought to check for it, if you go the the settings menu for the phone, you can check what's eating up her battery (Under Settings>Power>Battery use). I also found it helpful to look at what apps were using a lot of data because that would also drain the battery. You can check that at Settings>Usage. If you go the settings within the usage page, it will let you select an option to view WiFi usage as well. Then change whatever settings you need to in the apps that are using a lot of data.
Also suggest getting a new battery as they do become weaker overtime, I have tried many roms and there's little difference in battery life. People will believe what they want, and everyone uses there phones differently

While I understand that a new battery may help, that is not the issue. The issue is that battery life is fine on Thursday pre ICS OTA and horrible since.
What would factory reset do to fix battery life? Does that reset battery stats? Is resetting battery stats the issue?
Give it a try, and make sure you turn off auto light control, reduce email sync
Sent from my HTC EVO 3D X515m using xda premium
Yeah, did those things. I really don't want to reset/wipe data...
My battery doesn't last more then 4 hours after the OTA ICS update... I'm looking in to root options.
