Here is something I just noticed I sometimes wipe my battery stats once I get a full charge on a new rom. I always wipe and flash using fastboot boot recovery.img.
Roms always run fine smooth no issues. But for some reason if I go and wipe my battery stats after a full charge my gauge will lock up and the battery chart doesn't work anymore...
Even a reflash and wipe doesn't help. What would cause this issue?
Im on hboot 1.5
I know back when I would just flash the boot.img then the rom.. I never had issues wipeing my battery stats....
So anyone else have this issue?
I know folks say you don't need to but some times you do need to if you flash a rom and for some reason your battery gauge sticks at 99% green light... Will never hit 100%..
it eventually will hit 100%... you have to charge it while the phone is off just once and it will green light while off... then boot up and charge again and it will hit 100...
also, what exactly do you mean by the battery chart??
it shouldn't have an issue because your voltage/charge is monitored by the kernel... kind of an odd little anomaly to be honest.

here's the thing, the reason why you are not seeing anything in your battery usage is because that's exactly what the batterystats.bin file is - it is a data dump of statistics... what has been using your battery, for how long, all kinds of mathematical outputs of screen on usage, awake time, apps, so on and so forth... converts all of that into a percentage and that's what you are seeing in your settings/battery usage.
so, accordingly, when you delete batterystats.bin, all of those statistics are gone and you have nothing to display. after a charge cycle or so, you will see that information displayed again.
again, batterystats.bin is simply the statistics of what has been using the battery. has nothing to do with the phone's actually ability to display the correct percentage, get a full charge, etc... that is ALL the Linux kernel which is your power management for the device.
wiping batterystats is truly unnecessary. does nothing for your battery life, and flashing a ROM then wiping battery stats is useless too because when you flash a ROM you wipe data... and the batterystats.bin is found in /data/system... so effectively you are wiping battery stats every time you flash a ROM.
but to go back to the OP... not sure why your percentage is not being displayed correctly... sounds like a ROM issue.

Ya I pulled the battery let the phone discharge and put it back in finally got everything working again ... I was on nightlys a few days ago and flashed one last night that was when I had some funky issues with the battery gauge after doing a wipe.
I only do a wipe if the gauge gets dicked up...
Anyways thanks man... Hopefully I fixed this sucker...
yeah, definitely was a ROM issue...
hope it's worked out and no problem man. hope all that rambling made sense, haha.

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.
Samerhing happens to me... and I just took it off the charger and I'm on 96 percent in less than 1 min

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

Hello guys,
I have a problem with battery :
Every morning, after booting, my phone was powered off over all the night, I can see my battery decreasing by 10%!!!! And I sometimes notice after few minutes that it increases itself bit by bit...
I've already did a battery calibration, but not after flashing the new Siyah' 2.0 kernel.
This is very annoying, and makes me wondering if I should recalibrate or what...???
BTW, the question is : HOW ?
Some say you have first delete batterstats, power off, then full charge.
Others say you have to power off, full charge, manually delete batterstats.bin, or use Battery Calibration App.
What is the f*** best way to calibrate our battery ?
I'm really pissed off loosing 10% battery with my phone powered off every morning...
Regards.
Using Revolution 2.7.1 ROM with SiyahKernel v2.0
This might just be the ramblings of a mad man, but I have been thinking lots lately about battery calibration on the sgs2.
Normally on most android phones the power off charge is completely independent from the rom so that if you charge when powered off you know it is really a full charge, not controlled by pre-logged battery stats, you can then wipe the stats and get a better idea of what "full" is when you are powered on.
On the SGS2 the charge when powered off is still controlled by the rom (see the app "no moar powah" for an example of this), therefore it may still be under the control of the same battery stats so may not indeed charge any more than what the rom thinks is full when you are powered on.
Wow, thanks for your explanation...
But, it makes me perplexed. If you're alright, you mean that battery calibration doesn't work on S2 ?!
So, in this case, how to solve my problem ?

the best thing you can try is to run the battery flat, charge while off, wipe battery stats anyway and hope for the best.
Will try it again ....
Maybe should I flash another rom after full wipe, or stick to a stock one.
I can't imagine that my battery is defected yet !
Maybe this could help :
Just after full charging, use Battery Calibration App, and notice it didn't delete Batterystats.bin in data/system... I've always use it and never pay attention... (maybe error with SU permission ?)
Very strange, so this time I delete it manually.
Maybe, it'll calibrate my battery well this time.
Wait n see.

Weirdly, I noticed that yesterday! I don't think it works on all roms, I'm definitely going to do it manually from now on.
My first current conclusion :
The best way to calibrate your f*** battery is definitely to do it manually.
Just delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
That's all ATM.
Why ?
Because, I've just noticed that Battery Calibration App doesn't always delete this file. Ya, sometimes, It works, but sometimes It sucks. I don't know why, but seems to be related to some SU version and permissions' bugs...
Hope it could help some of you.

Is that the same as doing it through Clockworkmod advanced/wipe battery stats?
It is normally the same thing, I prefer IMO to do it manually.
Just trust yourself
And im not sure what to do. I need some advice because I just cant find the issue! This morning was the final straw, my phone was at 100% charged and all i did was take about a 3 hour nap woke up to an over heated phone and the battery at 10%. WTH?? I use cpu spy and juice defender and nothing. I barely have any apps other than a wellsfargo one and 3g watchdog. Im running [ROM]<=TASK650's ICS'd OUT! V5 right now and i just switched over from cm7 because i thought maybe that would've been the problem? I dont know if its a deep sleep issue because ill look over at it sometimes and the screen just turns on out of nowhere and ill have to press the sleep button for it to turn back off. It also like to randomly turn off as it please. AHH THE FRUSTRATION .
Anyway enough rant can someone help? Or at least give some advice on what I should try or do? Thanks.
Your screenshots are inconsistent with your stated behavior... Loss of 20-30%/hour and an overheated phone says the thing is stuck at 1200 MHz and full load - but your CPUSpy graph shows only 9% at 1200, and a total of maybe 40-50 minutes since reset.
Also the battery graph in your first shot has a major discontinuity... It drops from 100% to 10% instantly. I've seen glitches of 20-30% jumps at a time after a fuel gauge reset, but never anything like that.
So then what your saying is I should kill it with fire and then return it and grab another one? lol I dont know anyone else with this type of situation. Im not just one to go and ask a question because im too lazy to search. I swear i looked and googled EVERYWHERE for some type of solution but i just haven't found someone with this type of problem.
as Entropy mentioned, that jump in the first screenshot makes no sense. You should probably recalibrate the fuel gauge.
Looking at the 2nd screenshot, a lack of deep sleep seems to be the culprit. You'll need to track down what's keeping your phone awake. I've read something about exporting the wakelock log but perhaps there's already an app for that...
Also, clicking on the graph (in the first SS) will show you a more detailed burn down which might help isolate the issue.
Lastly, did you change kernels as well?
Im sorry im fairly new at this. It just has the kernel that the rom came with. I recalibrated the fuel gauge like you said and retook some screen shots that ill just leave here. It keeps over heating and Shutting off on me every half hour or so. On top of that The battery just drains in a mater of 3 to 4 hours. I think the problem is just the phone itself. Im going to try and put the original stock rom on it later this week when i have time (Finals are driving me crazy) and then Im going to try and send it back and get another one. I might need a usb jig thingy tho. Its very frustrating this phone isn't even a month old and like i said before i googled for a full hour and a half and I just couldnt find a solution to this.
mmmk this just happened.
That certainly doesn't look normal. When it takes those sharp dives is the phone rebooting? Also when you flashed your new ROM did you wipe all data in cwm first?

I had a similar problem (phone got extremely hot) when i first flashed to UnNamed but after re-calibrating the fuel gauge a few times everything was all good.

Suggest running better battery stats from a full charge and when you get that instant drop go into bbs look at partial wake locks.
Also have you done any
oc/uc ?
Running ICScrewD ROM

Yes it shuts off every half hour or so and when i realize it and turn it back on the battery is drained significantly and yes i wiped all the data in cwm.

Ok Ill definitely give that a try the moment I have a chance and report back here the results. I haven't done any oc/uc either. Thank you guys for taking the time to help me figure this out.
I would try a CWM Backup. Then Factory Reset, Cache Wipe. Then install a fresh copy of Task v6. If that doesn't fix it, restore back to your backup you did.
I was having fun with undervolting myself (would crash my phone). Every battery pull I did, I lost 20-50% battery life. JUST turning the phone back on! Though in my case the phone would stick at this percentage for a long time, then when it caught up, eventually draining. I would assume the battery was not calibrated, but people keep telling me "this battery does not need calibration" (Whatever).
It seemed to fix itself for me though, after letting it drain down a bit more. I let it fully charge this time with the official wall charger. This was with Task & Siyah. Has not happened since.
I hope your battery works itself out!

kk so I'd guess your battery really isn't that low, it's just reading low after those reboots. For whatever reason sometimes the phone will show a significant loss after a reboot, but really didn't lose that much. However something still isn't rite obviously. I'd suggest redownloading your ROM and clearing/wiping everything in CWM. And do a fresh install. Someone might be better able to help, but if I was getting random power downs that's probably what I'd try. (I might be wrong, but I don't see how wakelocks would be causing it to power down)

Thanks for the input everyone. I just got back from class now and my phones dead no surprise there but Im gonna let it charge back up and ill repost some screen shots of cpu spy and betterbatterystats since i just got that running on the phone. Afterwards Im going to try to just wipe everything on cwm reinstall a rom and see what happens from there. I bought a usb jig that should be coming in by the end of the week just in case all else fails and i'll just send it to att and have them ship me a new one. Thanks for all the feedback you guys are awesome!
OH I forgot to mention I dont think the phone actually shuts off because I was talking on it for a bit but i was talking through my bluetooth headset. I went to check if i had a text message and the screen wouldn't power on but I was still able to talk on the phone WTF? Makes no sense to me.
Really starting to wonder if your CPU has voltages it can't handle...
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.
Cheers.

Yes your coincidence is just too much, hmm.. Weird.. I don't know what to say? Battery Recalibration? Beat a myth with a myth I say.

Hello everyone whenever i check bbs or gsam battery widget or wakelock detector there is no wakelock but the thing is that after 1 hour or so whenever i check my phone i lose 5-6 % .That means not even 1 day of standby
what could be the problem? i've tried like 20 roms and different kernels and still have this issue..
Im currently using walkman style rom and Kappa kernel

Do you keep your data/wifi/auto sync on? If so disable those to reduce your battery drain.

Just cant figure that damn thing it aint showing on the monitoring apps
Even on stock rom the problem persists!

Which is your current ROM and kernel?
To fix this you could do the following
1. Reflash the phone's stock OS(preferably GB or ICS)
2.Just in case re-calibrate the battery via cwm or an app.
3.Run with the stock ROM for a week without installing any other apps.GO STOCK!
With this you can know if the problem is ROM or Kernel or you battery.

Re-calibrate via cwm or an app...do it properly(full drain and full charge cycles)

Okay ill probably let you know 4-5 days later till the cycles are complete
For all the smart boys out there, there is NO such thing as battery calibration. All that kind of stuff on the internet is complete, apologizes for my language, bull****.
To OP: Post screenshots of BetterBatteryStats info and Android's own Battery info screen.

Force deleting the batterystats.bin file is battery calibration. This is the closest thing a user can do to properly set up the battery monitor chip.
The file is used by the chip set which monitors the voltage across the battery to give out the % reading. It's normally reset by the chip itself if we charge the phone up to 95%+ each time. But improper flashing of roms will cause residue data to remain resulting in a error in the %.

Wrong. I have no idea, where you are taking this from, but this is completely false.
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

So, all those stories, which you have heard about batterystats.bin file removal improves battery life is false and just a placebo.

Well thank you. You've completely changed my conceptions about battery! I apologize for any wrong information I may have provided. So I ask you is there any other way?
Right now my phone switches of on 10% all these days I've believed it was just a file problem but since on reading the article I can see it's not. So is there any other way to properly make the phone show the proper battery left %?
Mine dies just at 10% is there any way to correct the problem?

You can try deleting the batterystats.bin file, but I am 100% percent sure, that this won't fix your problem.
Though I have not been active on this section of the forum, I can not provide any other solution. I know there have been other threads, you might want to try searching on the forum, if there are any solutions.
