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

Unbelivable battery drain!

I have my LG 4X for about 3 months!Everything was great until today.I charged it this afternoon and now,after 7h10min it`s on 50%! WTF? I didn`t use him at al! Maybe 5 min of internet..In 20.00h i went for practice and left it at 74%, killed Wifi and when I got back at 21.55h it was at 54% and it`s still dramatically dropping! Is the battery dead? Help!
P.S. From 7h23min of battery it was 7h13min on stand by..46%..

R: Unbelivable battery drain!
The charger usb cable not touching all the pins. Try to clean usb port

Sometimes after charging the phone I notice high drain after 3 hours it is as low as 50%. I checked with cpuspy that the phone wasn't going to deep sleep at all, it remained at 475MHz when the screen was off.
This has happened to me twice.
Only solution I found was reboot.
Hope it helps

How do I do reboot?

Press power button down and select the reboot option.

I thought there was a reboot app...
I did that and now it seams stable..It "stuck" on 27% for about an hour with WiFi on..Wow,it gave me a little scare..I hope this will solve the problem for good!:laugh:

If you installed Chrome at some point, you might want to find the option to turn gps-positioning off as well. Not sure if it's been fixed in a later release, but on the previous version the api prevented the processor from idling, and never turned the gps-antenna off again after use.

It's most likely an app is causing that drain, try installing BetterBatteryStats...

how can we know which app is forcing the phone to does not enter deep sleep mode? i installed cpu spy and note that deep sleep mode is not being used by my phone since yesterday, but ysterday i rooted and installed all my root required apps, but i don't know which is avoiding deep sleep mode.
I just turn on the phone after full charge, and in 10 minutes battery had drained was about 7% and the phone is warm, obviously something is running on background or something, i closed all apps that I know and used Greenify to stop background apps and now i close all google+ apps, i will measure again

i solved my problem, it was caused by the google+ app, I just logged out and the phone can enter in deep sleep mode again...

Lolz, you need to give somemore information
1. Did you root your phone? which firmware are you using? if you are rooted did you do factory reset?
2. did you do anything related to flashing JB, unlocking bootloader, etc or anything that happened recently to LG 4X.
3. what app did you download or updated 1-2 days before this?

[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?

I9000 shuts down randomly stock 2.3

Hey Guys, Quick problem My old i9000 randomly shuts down by it;s self, i've flashed back stock rom and stuff but is it the battery or software? any fix? P.S phone is 3 years old now and my dad is using it and he is pissed off.

Probably a hardware problem
Sent from my GT-I9000 using XDA Premium 4 mobile app

Can you specify better your question:
have you no more problems with the i9000 since you flashed back the stock firmware?
If it's fine now, it might have been only app update: app developers sometimes "forget" one of other older Android version and simple update of any app might cause biggest problems imaginable.
Restoring a nandroid backup and updating apps manually can save you lots of nervs.

Also, how's your battery? Sometimes its a case of needing a new battery

Ok, The phone running stock 2.3.4 NO apps installed, not rooted, no custom kernel.
The phone just shuts off randomly while not being used OR sometimes when you click the power button to shut the screen off. Also as a side note, when i plug the phone into charge, it says 100% fully charged 10 seconds later but when you unplug it, it goes back to what ever the charge was before plugging in.
I've tried to describe it in the best way possible, so any ideas?
thanks

I would think a prob with your battery ...can you check that ???

Yet another thread about the battery?
Yours sounds like a more serious problem, but you could at least search and find the standrd trouble-shooting - check what is reported as using the battery for a start?
1% in 37 seconds cannot possibly be a software issue - even running every app, all hardware and CPU/GPU at full wouldn't do that.

i can imagine only one way for this to happen. perfomance governor or u did something wrong there thats buging the cpu to work 100% permenatly. use an app to watch your cpu usage, does the cpu go down to 102 when u do nothing or it stays up to 1000+ ?
if it stays up 1st thing check the governor and 2nd use wakelock detector to see exactly where the bug is so you dont do it again after reflashing the kernel.

Yes it does seem to go down to 102 but now the battery goes down 1% every 1 and a half minutes which is still too quick. Is it worth a factory reset? This problem occurred spontaneously so it has nothing to do with the kernel.

1% every one and a half is fine. everyone has battery drain around that percentage

Oh if that's the case then I should be alright. Its just that when the screen was on doing nothing just awake it went down that quickly. But whenever I'm doing something on the phone while its charging it still goes down which it never did before. Do you think its a software or hardware issue?

It still depends on what you are doing and whether you have Wi-Fi, Bluetooth, high brightness, high CPU etc while you are doing it. When I used to play Ingress my battery would go down quicker than I could charge it - either from a high-current car charger or from my external battery pack.
