Battery percentage problem

My SGT is having a strange battery percentage problem. The battery was at 95% and the unit was on flight mode last night with no apps running. This morning it was dropped to 78% (over about 6.5hrs). So I turned it off and restarted, the battery percentage was back to 94%.
For some reasons, the battery percentage is dropping way too fast until I restart the unit, it seems like android is reporting a wrong battery percentage. Or could it be the battery? Does anyone experience the same problem? Any solution? And what is the normal power consumption under flight mode for other SGT user?
I just did a hard reset (wipe cache/data and reset to factory) to see if it helps and I am not installing any apps just to keep it in stock condition.
Thanks!

Generally, about 3% lose of bettery during the whole night with mobile on, while power meter may go wrong on Android devices, for example XT701 is.

So the XT701 has the same problem? How do they resolve this?
I start to think if I should take it to Samsung for repair.

Any help guys??
Would flashing a new firmware help the situation? I am tired of rebooting the tab so often just to get the right battery percentage report.
Other than this issue, the tab is PERFECT. I just wanna get this over with and enjoy using it.

Still looking for helps.....

Galaxy Grand Quattro: battery is fine, just the prob is with the indicator
Galaxy Grand Quattro : while charging it suddenly jumps from 78% to 100% and asks to unplug the charger. When i unplug it it shows 78 or 80% back again !!! I believe that this is related to software issue. So i have done a factory reset, but no use. someone pls help if this is a known issue.. Googled abt it but dint fine anything there.. Thanx in advance.

Have u tried a different charger? It might be the charger not working as supposed. Also how old is the battery and is it an OEM? It might be old and not working right also

[Q] Wipe battery stats

Sry to ask this but how do u wipe battery stats properly?
Is it let the phone fully charge first, then go to recovery to wipe battery stats and then let my phone battery drain (no charging allowed) until phone is completely dead. Is this procedure correct?

Just install battery calibration from market, easiest way to calibrate your battery imo.
Sent from my Incredible S

Go to recovery mode and in advance menu wipe the battery stats, I think it is the proper way to wipe battery stats

the correct method for proper calibration is charge to 100%....then wipe the battery stats...drain the battery to zero....charge to 100% again...now use it normally. but i am too lazy to do all this so i just clear it.i dont think it would harm.
however if you dont clear it you will get inaccurate readings on ur battery percentage.

in my case sometimes it loses 10% if i restart my phone

turn off the phone, hold down decrease sound button and push uper button. go recovery and wipe stats)

Thanks for all of your replies as I am lazy, I just download battery calibration app from android market

I calibrated many times my battery.. But when I reboot to recovery, I always find either the battery shown in Ext recovery is lower or higher that what I saw in the Rom.. And after rebooting from recovery to Rom, the Rom shows the battery shown in recovery.. So whenever I reboot my phone, I find the battery % change in Rom... Do anyone experience this..?

this is due to incorrect values shown by rom..dat's y calibration is required

yes i already said this is due to my laziness ...i never bother to calibrate properly.

So how often should you re-calibrate your battery?

[Q] Battery drain on miniCM9-3.0.2

Hi all!
I am using rom miniCM9-3.0.2 by nobodyAtall. I love this rom but battery use about one day... I've just used basically function. I try to wipe battery stats, remove unused applications... but nothing changes. Anybody knows how to solve this problem?
Thanks so much for help!
(Sorry for my bad english)

Use smartassV2 as cpu governor under performance settings,might increase battery by a margin,but as for now there is no solution for this problem,use minicm7 based rom if u want better battery performance..cheers..

I'll try it. Thanks u!

Try to tick" use 2g only" option! there's a bug here, you need to re-tick it every time you re-boot your phone.

1-Charge your phone to 100%
2-Poweroff your phone and leave it charging for 1-2 more hours
3-Boot on CWM and wipe battery stats
4-Go to build.prop and find this line "ro.telephony.ril.v3=1,icccardstatus,skipbrokendat acall,datacall "
Add qcomuiccstack at the end of the line. It should look like this :
ro.telephony.ril.v3=1,icccardstatus,skipbrokendata call,datacall,qcomuiccstack
5-Enjoy
I've done that and my battery became immortal

Just a question: Power off phone and charge? What do you mean by that? Every time I power off my phone whilst charging it boots up again immediately.

i just power off and then the phone stucks in the kernel logo with the led on. I just assume that the phone is charging its my 2nd day without charging and i still got 30% of battery that i think will last for another day

Thanks !
I'm going to try just that.
My battery drains in about 8 hours now (when I'm not using the phone at all).

Hi does this work for minicm7?

Battery drain when rebooting phone

I have 2 batteries and one broken phone, I use the broken phone to charge the extra battery. If I reboot my phone with a battery with a perfectly good charge when it reboots it shows the battery is dying? If I put the battery in the other phone and charge the status says the battery has a charge, not sure what is wrong?

My guess: Your broken phone doesn't actually charge your battery or at least, not fully. It might think it's fully charged at a very low %.

It could also just be the os not reading the charge correctly. I've had it happen on numerous occasions where I'll reboot my phone and the charge drops by 20-30% after reboot. But if I continue to use it without charging or rebooting the percentage will eventually increase or at the very least stay at one level for an extended time.

Well when I take it out of the broken phone and put it in the good one, the good one says its fully charged too. The only reason the charging phone is broken is cause the IMEI is toast.

It doesnt increase, just dies......... tried charging the battery to 100% turned off then ran battery optimization app, used the phone for a while and rebooted it at about 60% and after the phone rebooted it said the battery was at 2%

You should probably stop rebooting, let it die and fully charge it. Might need to recalibrate your battery stats too.
As for your IMEI being toast, you can flash stock KK4 to fix it.

Thats what I did was let it die and fully charge and used the battery recalibration app to change the stats. then rebooted later and lost all my battery?
Have tried flashing stock KK4 with no luck on it, now its just an expensive charger

Ok.. maybe we've been missled this entire time. What's the highest battery consumption in settings->battery?
Also, you could get betterbatterystats app to help trigger what's draining your battery.

Well what I'm starting to think is that the way you charge your battery has nothing to do with it. The OP missled me to think that it was coming from your broken phone. It might come from your phone (or app/setting on your phone).
Imo, backup your apps and such (after finding out what's draining your battery), flash back to stock and start from there to get back to your ROM.

How old are the batteries?
Do they both report the same percentage immediately after boot and after comparable use for a similar amount of time?
They are only good for 500 to 1000 cycles. A dying battery will appear fully charged when on the charger but quickly drop to a lower voltage when used.

Eh yeah, I would highly suggest backing up, going back to stock and reflashing your way up.
MediaScannerService is probably cause your SD card is a mess, a factory reset usually helps for that. AudioOut_2 is weird though, do you have clicks sounds on?

Run a full battery cycle without it on. I'm pretty sure I saw this issue before.
For the media, it can be a few things but cleaning your SD card can help a lot.

What's the error? You external might've been the problem all along. I would suggest to copy the files that are on it to your pc and format it, see if it works.

Wipe battery stats in clockwork mod recovery and check. I hope your issue might resolve by wiping battery stats..

Connect it directly to your pc (not through the phone) and see if that works. I'm pretty sure your external needs reformat.

[Q] Battery Drain Problem

Hello guys I'm using a Galaxy Note GT N7000 on CM10.1 with NX Kernel
Recently I've been having a problem of battery drain. Even when I have put it in charging, the phone seems to have been draining out of it. I have tried to change the USB cable and the charger both, but still the problem persists. Does this mean that it'll get solved by a new battery? or there is some other issue causing this problem? Would wiping data cache or battery stats help? If so, I'd be glad for your help! If you require any more information, let me know. Thank you..

Witch nxkernel version are u on and have tried to full wipe everything and start from scratch the other thing is if its your battery you would probably be seeing stuff like your screen flickering and then the phone shuts down after reboot you find you have 1% battery that's the normal battery signs but other then that if it is dieing when charging you would have a huge drain and a fresh start could fix also you could check some battery stats see if something is staying active and could be an app doing this as well.

Hey I tried the following:
1. I tried a brand new battery but it didn't affect anything. I still tried a few more adapters and cables, nothing.
2. I did a full factory reset and the kernel was stock Cm kernel.
Still, the problem is persisting.
The NX Kernel that I WAS using, was version 1.3.9
What else can be the problem? Thanks in advance.

What governer have u set? And have u overclocked it?
