If I do a backup in recovery and try another rom, when I restore the backup does it also restore battery stats? I ask this because when I flash a new rom I use battery calibrator and wipe stats, but I hate doing this everytime. So, if I have a rom installed that has the battery calibrated and do a backup, then wipe stats for a new rom, and then restore my old rom does it still need to be calibrated?
This has been nagging me for awhile, so a big thanks to anyone that can shed some light on this situation.
I think it may backup yeah but not certain. It doesn't matter anyway u not really need to do this any more. (except, I suppose, in extreme battery drain circumstances)

Battery stats simply records how the batter has been used over time (since the last full charge.)
it has nothing to do with "Battery Calibration"
so don't worry just use your phone it will maintain it's self

That's a load of BS.
Battery stats indicates the % to the ROM.
In order to calibrate de battery u need to let it charge to a 100% (preferrably with phone off) and powering on and entering recovery to delete the file. After that unplug and restart the phone. Battery should be calibrated

Incorrect.
the Batterystats.bin has nothing to do with the level shown to you.
this is managed elsewhere
also once the phone reaches 100% it deletes the file it's self.

Hi,
I have started using the Verizon extended battery but I am noticing that what my battery display shows and what I see with the battery widget I use are different.
How do you reset battery statistics on the TB?

If rooted, download ROM Manager and flash clockwork recovery. Reboot your phone into clockwork recovery (using rom manager or the extended power options) and then go down to advanced>wipe battery stats.
If you are not rooted, then you cannot wipe the battery stats. I would suggest you try the battery calibration app on the market (I forget the name as I've never tried it) - might help bring the numbers in line. *Edit* Just realized the Battery Calibration App on the market also needs root ... so basically, unless you have root, you can't wipe battery stats.

The app is called Battery Calibration, and it works great. Here is a link to it.

Do that and your battery should perform much better. Mines been unplugged for over 27 hours and still at 40% remaining with normal usage. Never had a phone with this good of a battery.
A different method would be to use this app, it also deletes the Batterystats.bin file. Full charge also recomended.
Can someone please help me with this issue? My viewsonic was not showing battery levels properly. I always says 100% and at times just powers off. I check battery setting, and later tried to wipe my battery stats. After that all hell broke lose. Trying doing a wipe and restore in ALL aspects but I cant get it to reboot from back up or previous operating system.
Urgent help required

There is no fix for this at present. But, see this thread for a script you can use to estimate your charge percentage using an alternate method.

Do you have ClockworkMod Recovery installed?
Something grong with cwm? my batt always reported very good until I wipe battery stats in cwm, bad idea, now always report 100%.
Don't use wipe stats from cwm, it does not fix anything and could be worse.

It's a HW issue--nothing to do with CWM or wiping battery stats.

Yeah, mine says 30% until it suddenly drops after a few hours. I just deal with it.
Hi, i've encountered some issue with battery since I installed this ROM.
I had some freeze and when I rebooted the phone the battery level dropped down of 20-30%...Also during the charge the behaviour was not "normal".. I can post some screenshot to made my explaination "visible".
The first time I had this problem, I reflashed the rom after a full wipe (data and cache) and after i hadn't performed the backup but installed the apps one by one from the store..that not solved the problem. I uninstalled set CPU, I also changed the battery...same freeze and same problem...Any advice?
Thank you!
Try another rom .

I`m using same rom but never had issue with battery. I suggest you to use phone until battery will be 0%, use until phone will shut down itself. Leave it off and charge battery for 7 hours. Turn it on and find on market battery calibration, calibrate the battery. Also you can try to change kernel. Good luck
Thank you all. I'll try to calibrate the battery (i think that it is clear that is not a battery problem) before changing kernel and then ROM.

Of course...asap i will try and i let you know.
Thank you.
strange that because im getting better battery life than i did from stock gb although i have frozen all samsung apps through titanium im amazed really. It probably takes a couple of charges to sort the battery on a new rom.
Well...I've performed the cleaning of the kernel..and installed a new kernel. No matter which kernel: the battery behaviour is the same. 30 minutes ago screenshot.
I'm going mad
Have you tried another battery, doing full wipes or reflashing rom

I tried with another battery.
I did a full wipe.
I refleshed the rom after the full wipe.
The only thing to do is change the rom.
For the moment I unistalled some apps (Set CPU was already uninstalled..now I deleted Rom Toolbox)

I agree. I myself am using Omega Ice Cream Sandwich 10.4 still
At the moment the problem is gone...propably it was due to the apps setCPU and Rom Toolbox..both set the CPU.
I continue to check the behaviour..the battery life is about 14 hours...maybe it is possible to set the phone to do better..more battery life...
I have JXD s7100B with Android 2.3.4. After rooting it and killing cell apps (and all unnecessary apps) it's battery lasted about 4 hours and it was OK. I used Battery Calibration from Google Play to try and get some more and after that it started acting weird: It could not boot (it would loop the bott screen) unless it's on the charger. After it boots it would drain the battery in less than 20 minutes! When I try to charge it it would charge to full in 10-15 minutes but when I disconect the chatrger, it will again last <20min.
After a few days it started acting normaly (booting and battery life) but few days after that it started the same again:cannot boot unless on charger and lasts <20min. I tried recalibrating battery again with Battery Calibration, reflashing firmware with custom rom and with original rom from the manifacturer - nothing. It still acts the same.
Once, while using bitrider's custom rom (I still can't use URL's ), I booted it and got black screen with no icons nor drawer (i guess launcher crashed) but with only the notification bar (battery level notification, working clock) and touch screen not working. I left it like that to see how the battery will work and it lasted normaly! After that I experimented with two original firmwares from the manifacturer and it drained battery fast like before. If I start JXD in restore mode battery lasts long there too.
So my guess is that battery is OK but software somewhere in Android is reading baterry level of 100% as 100% but of 97-98% as 15% and it forces power off although battery has juice to power the tablet. Is there an app that can tell to Android how to see battery or could I do it by editing the firmware somehow. Enything to make it work like it did.
Do you have a custom recovery? If so, I think there is some way to delete the battery configuration files from recovery. You charge the device until it says it's full, delete the files via recovery and then boot normally again. Then the OS will regenerate the files.
This is the same thing Battery Calibration should do, but maybe it's doing it wrong or something.
It could also be that you have some app that is draining the battery. This would explain why the battery lasts longer when no apps launch. Install BetterBatteryStats from the market to see if some app you have insalled is causing wakelocks (these drain your battery a lot). It is a paid app, but if it fixes your battery life, it's well worth it. You should probably try this before the other thing with the recovery.
Thanks for quick answer

Did that and nothing changed . I charged it to full and used Root explorer to delete batterystats.bin in /data/system and OS made another one but it did nothing.

Done (on your advice): nothing on the lists last longer than 20 seconds (I've just turned it on and let it drain). Application doesn't explains why I can't start it without charging it, why, when I deplet it, I only need to charge it 10-20minutes to full and why it happens on three diferent firmwares (Theoreticaly, maybe the same firmware - one on english, one on chinese and one made from chinese, but that chinese (original) worked normaly before Battery Calibration).
Well, apologies for making you waste money on that app when it didn't help then
Have you tried reinstalling stock ROM after doing a wipe in recovery first and just starting all over again?

I've reinstalled stock ROM a few times but I didn't do wipes. I just did it one after another. I'll do a "wipe data/factory reset" from recovery mode and then install stock ROM. I'll post here what happened.

That might be the problem then, I believe installing new ROMs without doing a "wipe data/factory reset" can sometimes cause issues.
Same . I've done data wipe/factory reset from recovery mode (it has nice "are you sure" screen 7 "No"s + 1 Yes + 3 "No"s) and then installed stock chinese ROM but again battery starts draining 3-4% per minute. Is there a partition in Android that doesn't get wiped with factory reset?
The system partition does not get formatted when performing a wipe "data/factory reset". Can you check to see if you can format the system partition in recovery?
That's an interesting information. I'll see if I could format it somehow. Options that I have in recovery are:
-reboot system now
-apply update from sdcard
-wipe data/factory reset
-wipe cache partition
-wipe media partition and
-reboot into factory test
Has anyone ported clockworkmod recovery for your device? If so, that recovery has the option to format system. Has someone created an all in one wipe that included formatting system for your device?

Any super wipe script should work
It sounds to me like your battery is actually faulty. Try another battery, or put yours in the freezer for about 30 min, then charge.

Fixed it!!!!
User named Friend on the apad forum posted that he found somewhere how to fix this issue and I tried it and fixed it. Thank you all who tried to help me - it is nice to see normal, helpfull people on the net. Thank you very much. Here's how I did it with the image for an easier orientation: goo.gl/XpC5I (can't post urls yet but this works. It leads to apad forum where it all started). All the best.
Glad you were able to fix it and good luck with your tablet. Hope everything goes well.
