Battery stats question

I was just curious if the battery stats battery.bin file is deleted after flashing any new rom or kernel? I have done a search and found only this on it...http://forum.xda-developers.com/showthread.php?p=12355666
I thought it was but after seeing this I'm not completely sure

No, that is not deleted in a flash, thats why it is recommended to flash at full, bump charge after flash, then boot to recovery go to advanced and delete battery stats, there is no confirmation after but don't worry its been wiped. Now go through a couple charge cycles and your battery should settle in and be calibrated correctly.

Thanks I was very curious on this and will go ahead delete the stats

Battery drain on my Note after flashing XXLS7 rom

Hi,
I recently flashed my XXLS7 ROM and while doing so, I was asked to wipe battery stats too, after then I see that my battery % is getting reduced drastically and the worst is that whenever I am in normal mode it shows me 75% but after getting into recovery mode it shows 55% or so. Now I am completely confused whether 100% is actually 100% or not. Any ideas on how to get this problem rectified?
Thanks in advance.

may be you need to do a clean install of the rom again.
use format/system and format /data this time

Thanks, I have tried that option too, but still no help..........

Be patient
Mine was discharging like crazy when media scanner was doing its thing -- just keep a charger handy and stick it on when it gets low. Eventually it should sort itself out.

boot into recovery and wipe battery stats again.. then charge the phone to 100 % and test again.

I had this problem in almost every xxls7 ROM... I tried everything, literally EVERTHING.... i made 3 wipes, format preload format system etc etc... Result is DEVICE IDLE eats battery... I CAN NOT figured out which causes this... But finaly, SweetROM solve the problem... I do not know how but it solved... I tried RR3, Alliance and Stock xxls7... All of them causes battery drain for me but i do not know if it is a problem of all... Anyway, just in case you can try Sweet ROM... At least it does not cause drain when you do not use it...

I have this problem too..
Nokia 3210 with PA Utacka

after restarting the phone go to settings>application>all>media storage and stop it.
on every bootup, media storage process consumes %5-10 battery to scan media files.
you can disable it but the gallery wont work.
you can use Quickpic instead.

[Q] [XPERIA T] Incorrect % battery indicator [SOLVED]

Hi,
I have the Xperia T, my battery indicator % remain 100% after use, when i power off my device and turn on again the battery have a big fall (to 70-80% deppend of hours of use) and over time it turns to 100% without charge, its crazy. It happens in T_Hybrid_V17 but not happens from beggining of install the ROM... one day suddenly occurs...
My bootloader is locked, the phone is rooted and ROM is stock based with a CWM for locked bootloader.
Ok, I read about the problem, i have not the option of wipe battery stats in my CWM, i read about "battery calibration" and installed and followed instructions of apk "battery calibration", dont works for me... I manually do the same process... i deleted the batterystats.bin at 100% charge... let the device power off on discharge... charge again to 100% and let it discharge... it dont works for me...
Well... i think ok... there are a new ROM with another Kernel included... new CWM included in XDA I try to change from JB 4.1.2 to JB 4.3 Ultimate Pure XT 4.0... and later OTA 4.1 and 4.2 well, the problem changes... is similar but not same... I do it "the calibration" and try the same as past... the new problem is... battery 100% and after a lot of use maybe it drops in real time to... maybe 97% ok... power off and on... 76% I use the device the bateery lvl drops to 73% after time and still there, it dont go up to 100% this is the difference, but the battery dont drop in real time correctly I attach an image of battery graphic. What can i do? i read similar problems on other devices, like SGSII, that is solved with "wipe battery stats" in CWM but my new CWM included in Pure XT (touch Philz 6.X) still not having this option in advanced...
I have Xposed installed now, but not when problem begin, i dont know what more to do. The battery duration appears to be correct but the % is not real.
I search in XDA forums about it, i see "solutions" on other devices, I read and read, but dont work for me.
Sorry for my english, i hope that you can understand this.
EDIT: SOLVED
-------------------
The problem was a hardware issue. I leave it in a technichal assistance , and they repaired it in 2 weeks, a main board problem, new mainboard and new IMEI... solved.

Yep. Everytime I installed/uptated ROM.
And when install a new ROM also made a "factory reset" from CWM. :/

No, I thought to reboot to recovery now and clean just cache and dalvik cache.

If you are on root and have a recovery like CWM installed, then boot to recovery, then go to advanced and there must be an option to clear battery stats or something (I don't remember exactly ). You must do this only when you have kept your phone switched off and then charged it to 100%. Then only do it, then it would clean the junk battery data and recalibrate battery.
If the same issue persists, "your battery may be faulty".
If you are not rooted, then I am sorry, I am not aware of any solution if there is any.
Press thanks if I helped. :good:

Try killing your phone to dead battery 2-3 times and then full charge in one go and then repeat it
Last trick in my bag of tricks

Charge it through twrp/cwm. If not rooted, you could try getting into that *#*#menu thing and try those battery options, i think i saw something there that might help
