What application is everyone using? I'm getting poor battery with 0.2.0 beta and I used one and it still persists.

Charge to full, boot into CWM and wipe battery stats.
Use until device dies from dead battery, recharge to 100%. Use as normal for a couple days. It should get better.

Google search "wiping battery stats myth debunked" or click http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
A google android engineer spoke very candidly on the subject saying it does absolutely nothing.
damn its all a myth ha I read that, good find.

yea read it was a myth a while ago
Flashed cm9 today and now my battery life is horrible, when it it's on the charger it takes forever to charge.
I had that problem also so I wiped everything and formatted everything and Redlands everything starting with cm9 v 0.1.0 2d , then flashed cm9 v 0.2.0 . Everything great

myth
maybe a myth and from everything i have read (that article included) it seems to be. but im ok with the placebo affect or whatever bc i at least FEEL like it has helped since i did it after getting on cm9 beta 0.2.0 or whatev. not on beta 0.3 battery has been sucked hard as all get out, but such is life.
I have a question/comment about this. When a ROM is flashed I always wipe and format /data, /system, /cache, /davlik-cache, and factory reset. At this time I power down and recharge although the recharge may not matter as the lowest I've been was 85%. After recharge I boot into CWM and wipe/factory reset again then allow the phone to reboot. Isn't the batterystats.bin file in one of those places I wiped/formatted?
Once it's booted I just turn off and power up again then activate. Out of all the different ROMs I have tried this usually works very well. There was only one time my battery life was poor after flashing and I tried a battery wipe app and it still didn't help. I finally attributed it to the ROM and flashed a different one. Following the same process the new ROM was installed and battery life is great again. Did this yesterday flashing Rocko unlocked 3.0. After 4 to 4-1/2 hours of heavy use, when I say heavy I mean heavy, I am still at nearly 70% battery. If it works the way it looks to, I'll be getting at least 10-12 hours on a charge, probably more.

Calibration
So what you are saying since I have a Photon with an extended battery even rooting it won't calibrate the battery. It sits at 1% for hours. Had an HTC prior and didn't have this problem. Waste of money getting an extended battery when you don't know when it is going to die on you.

Not at all. What I'm saying is I personally don't use ine as I wipe battery stats as part of ny flashing process and do my first boot on a new rom with my battery at 100%. That works for me.
If you're switching to an extended battery you may need to wipe battery stats. This can be done with a battery calibration app or from within CWM, if you've unlocked and installed a custom recovery.
BTW: Rooting will allow you to install and run a batt cal app but rooting alone will not calibrate your battery.

So I will be learning more about rooting. But I thought i saw where others who had extended batteries that rooted with calibration apps their Photon still didn't read correctly. I could be misunderstanding something. Newbie here.

I know, when you replace a battery
But my question really revolves more around changing ROMS. Are there enough differences between ROMS that would make a battery wipe necessary when changing ROMS to ensure accurate reporting of the battery level?
I'm wanting to know the same thing to... And I need someone to tell me how to do a battery wipe correctly.. Because I've heard of multiple ways of doing it.. I.e. Doing it at 100% battery then letting it die out.. Then I've heard to do it when your battery is at like 5% then charge to 100%...

I'm in the process of Method 1...I think I picked that up one of the Cyanogen-based ROM threads, saying it was necessary to do that to get an accurate battery status with the new ROM.
Hence my question...when is it necessary and what is the correct procedure?
I did method 1 of my post and it has seemed like it has helped my battery tremendously... From what I've heard it's necessary after flashing a new ROM. And I can't remember who.. But I think it was tazz that informed people about method one. Don't quote me on that though haha.
i usually do one if i notice ****ty battery life and all you need to do is let battery drain then after a good charge wipe your batt stat in recovery, atleast i notice a difference when done this way....
I'm doing method 1 now, trying to get the juice down but its stuck on 9% left. Hmm, making me think there is some truth to this. Not that I'd doubt a dev .... (Taz )

I don't know what's the most effective and efficient but I When I do it I let the battery fully die then boot it into recovery real quick, do the wipe then power down and charge.when it's finished charging I power on and use til it's fully dead, then charge fully again while powered down.
I've had real good battery life running conaps CELB 1.6 and 1.7.1

I have been flashing back and forth ROM and Mods... I felt my battery getting worse compare to stock (stock Rom removed lot of ATT craps and other unused app).
Now doesn't what Rom i use: S8, Unname and CM7. My battery died at the end of the day which should last 1.5 days as my normal use.
Hmmm... well I jumped onto the ship already.
But I have to thanks for all developers that cook Rom. You guys are best.
Battery lifestyle will improve once you build up cache. Was battery life good when you first got your phone? Probably not. After awhile battery life gets a bit better.
Sent from a Galaxy far far away...
I noticed the same thing when I flashed from UnNamed to S8.
I followed some other users' suggestions and reflashed at 100% battery life, allowed the battery to discharge all the way until the phone died, then charged all the way to 100% again without taking it off the charger. I just got 25 hours with moderate usage and about 4 hours of screen-on time.
download the batteryCalibration app from the market, it requires root and makes you charge to 100% first. After that let it drain and it should do better after a couple cycles.
If you delete your battery stats in clockwork the phone relearns them and works better. But it will be ****ty for awhile

None of these do jack on our phone. I've read the kernel source for our fuel gauge driver, clearly none of you haven't and are blindly applying HTCisms to a Samsung phone even though I've posted MANY times that diddling with batterystats does NOTHING WHATSOEVER on this phone.
If someone's experiencing bad battery life after flashing a new ROM, especially a debloated one like Unnamed or S8, they most likely installed a drainer app.
If you run Skype, nuke that crap from your phone ASAP. It's a known battery drainer, and it's particularly insidious because of how it drains the battery - the usage shows up as Android OS but it's Skype that is at fault.
I was running bionix from before I decided to switch. I flashed back to stock via Odin and flashed to ICS Passion v11. It's an excellent ROM but my battery life is abysmal. Just texting for 5 mins drains it about 8%. I have to charge my phone 3x a day in order to keep it alive. Really like this rom so does anyone have suggestions on what to tweak or disable to fix this?

Yeah same for me.. I had to buy the Samsung Galaxy Epic 4g 1800mAh battery.. It solved my problem. You can get one on amazon for like 20 bucks. It's totally worth it. For some reason the 1500mAh battery gets random drains on this ROM
It's not just this ROM. I have noticed it on all the ICS Roms. Some of the apps are not configured properly for ICS yet, thus the battery drain. When you re-install your apps using Titanium Backup try not restoring data.
Bump for possible solutions. The new battery is a good idea. I hear so many people claiming battery life is superb and mine is far from it. I never restored apps with titanium backup either. Everything was clean slate
When I was running ics, i had a few times where my phone would not deep sleep. I just reinstalled and it seemed to correct it.

When I first installed Passion V11 my first full charge only got me about 8 hours of use. I installed BetterbatteryStats and CPU Spy, and Battery Monitor Widget. I looked at the logs and saw that Beautiful Widgets was causing alarms and kernel wakelocks almost non-stop. After identifying the problem app and uninstalling it, my phone still has 70% battery with 24 hours of use.
You guys just need an 1800 mAH battery. The thing can last me a day and a half with no charge (assuming I put it in airplane mode at night). You can find it for $10-20 on Amazon or eBay.
To get best battery life all you need to do is "Charge Cycles"
For ICS Passion v8,
Charge Cycle means completely charging your phone too 100%, reboot and LET IT DRAIN UPTO 0%
Now charge it to 100% again without interuption and then reboot.
This is one/first charge cycle. Also get unused toggles off and remove unused widgets.
I would add that you need to go into Clockwork Mod manager by rebooting your phone, selecting advanced, wipe battery stats, repeat after drain to 0 and recharge to 100%

Best way to get the most out of your battery, hands down (although I never let it fully discharge. Got pegged once on another phone and it never held a charge again. My own superstitiion though b/c it was an entirely different manufacturer).
Also get unused toggles off and remove unused widgets.

This has been debunked but I still believe in it and what I have seen from my own personal experience.
Sorry for mistakes, hope it's not hard to understand
Looks like i have smth like this - http://forum.xda-developers.com/showthread.php?t=1515020 but on my RAZR XT910
When i bought my RAZR, everything was ok it was on 2.3.5 droid, when 2.3.6 released everything still was perfect, but when i started trying to setup custom ROMs, this issue started... I tried to get back to 2.3.5 through RSD - its not helped. Now i'm on T-Mobile 4.0.4, everything is the same.
Fully charged phone, idling, some calls, it goes to 80%, then it jumps to 20% then to 5%(during this, voltage drops to 3.5, but then goes up to 4.1-4.0 as it must be!) . Phone works well, it took about 4 hours for battery drainer to drain this "5%".
I tried to fully charge\discharge without using phone, i tried any tutorials that will help to "calibrate" battery. Nothing helped.
I think it happens when Voltage drops to 3.5, OS thinks that its discharged, but when it goes back to 4.1, battery lvl is still low.
Maybe someone can help me with this issue...
Now i just added battery info widget, which shows me Voltage, so i can understand charge lvl... thats annoying
And i cant go to Motorola Service(No official service in Russia) and cant return my phone, it will took a lot of time... and i think this issue must be fixed..
have you tried like the battery calibration apps in the app market?
i tried a lot of apps from market, and nothing helped.
Try do this:
Manual Calibration method:
A) Charge your phone to 100% (and let the phone charge for half an hour after the 100%)
B) Install bootstrap recovery
C) Reboot your phone through the bootstrap recovery program
D) In recovery go to advanced>wipe battery stats>Yes, wipe battery stats
E) Reboot your phone
F) Do 2 or 3 full charge/discharge cycle (100% - 15% < X =< 0% )
If this won't do, flash the stock rom and send it to RMA.
Never let the phone to reach 0% and die, your battery will take damages 'cause of that.
i think bootstrap cant be installed on T-Mobile 4.0.4
If you're rooted, you can install this
I've used it on the T-Mobile Leak without problems. Flashed the overclock.zip with it (But no overclocking on the Leak, the script won't work)
The risk is the wipe. I'm not sure, if it messed up with your Phone

That is true, but I wonder if Android seriously lets you drop your cells to 0%... It still has enough capacity to shut itself down without interruption. So I guess there might be an internal protection against reaching "real 0% charge".
Still it is not too healthy for your battery

thanks! razr is rooted, so it works!
now i'm going to test what Syriochan said
@sekall: yeah it is possible that 1% (or maybe 5%) remains, but it is also true that no developers noticed something during kernel developing for any android device. So it may be true but it's better to not let it drop under 10% or 5%
@amletika: Not sure if calibration app do the same (never tried one, always used this method) but i've had 7 android phones so far and battery life was always at it's maximum after wipe and cycles. (I believe battery stats are kernel or data related so i don't know if this will work for you, consider that maybe hardware is at fault in this case)

Please post back after you do.
I have setup ics bootstrap. And made battery wipe immediately, when my phone was about 3.9V and was saying its 5% of battery. When i rebooted it was saying that this is 30%. Then i charged to 100% waited a little more and unplugged. Its about 24hours of using with normal load, and there was no battery lvl jumps!! Thank you guys!
P.s. i dont know what battery calibration apps does, I tried a lot of them, but only wipe through ics bootstrap recovery helped!

Hello,
After reading other threads, I've decided that I should post my case to see if I get a better answer.
A couple of days ago after being with SuperNexus 2.0 for a few months I decided to try the stock LSS ROM, I didn't like it and went back to SuperNexus again wiping the Battery Stats in the process to see if my battery life could improve (I know it's a myth, but I tried it anyway). After this my 1.2 years old battery has been crazy:
- Sometimes it will completely discharge it doesn't matter at what percentage the battery is.
- Sometimes the phone will shut down like if the battery is at 0% and it won't turn on again, but if I connect it to the charger it will show some charge (close to the one it has before the phone shut down) and the phone will turn on again. After this I can immediately remove the charger and the phone will work like normal.
What I don't like is that just before the phone randomly shuts down, the screen starts blinking and/or the phone hangs (it doesn't respond to the touch). I'm worry this could be damaging the phone itself.
Please refer to the screenshots (there is not photoshop involved, I swear).
I've tried to charge it to 100% (trying to get it as close to 4.2V as possible), I have pump charged it (disconnect/connect the charger until it doesn't drop to less than 100% immediately), reflash the ROM (wiping/format system, data, dalvik, cache, etc. the usual suspects), etc. but no luck.
I know it looks like a faulty battery, but it has never shown this behavior until I sadly deleted the Battery Stats. Will a new battery solve the problem or it will just be the same?
Any thoughts? Any help/recommendation will be appreciated.
Thanks in advance for the help.
Cheers.
P.S.: I have to say that before all this I was running Dori 9.14, but I ran the Kernel and the ROM wipe scripts (I know the ROM wipe runs the Kernel script too) between flashes.

Wiping Battery Stats is never a problem, people even do that to reset Battery estimates, try a reflash and a more stable kernel. As far as I know Dori 9.14 is not playing nice with some people.

Yes it sounds weird that deleting a file will screw your battery, but the coincidence here is huge, that's what I don't understand. With respect to Dori 9.14 (I only used it for a couple of weeks), yes i was running it before I did all this, I'm now running the stock Kernel that comes with SuperNexus (which never gave this kind of problems before).
I also removed the battery to see if it was maybe a faulty connection, but it stays in place very tightly.
