My battery status acts weird.
When I root a rom the status and the battery drains in one hour...
If I flash a samsung firmware the battery drains normally... Even with overcome kernel and stock rom the battery stays at normal drain. When I root the tab the battery flips out. anyone can help?
Try to use "BatteryCalibration" from Market. But first you have to root you device.
Thanks for your try, but I´ve made ´t often...

Hy all,
Since some time I have big problems with my nexus 4 battery...
This problem is on all Roms and all Kernels for me, so I think this is directly a dead battery problem
WHen I use my phone, sometimes the phone shootdown randomly between 10% and 40% battery, and when I reboot it, the battery indicates 0% and shoot down immediatly after....
I tryed to calibrate, to put in the fridge (lol), charge via LG usb charger, via computer, via wireless pad, but the problem remains ...
Is it time to change the battery ? (PS my battery come from china)
Somebody can indicate me a GOOD battery reseller on ebay, or somewhere on the net, and who have express delivery in europe (not worry about price)
thanks a lot all
your real concern should be the random reboot...such battery drain is normal because the battery percent is only accurate right after a reboot. the battery drains extensively while on boot animation as well because all your cores and screen brightness is at its highest...so your battery is perfectly fine...for the random reboot im guessing its an app thats causing reboots..finding app = no reboots = better battery
Hi,
My S7 Edge G935v runing Lastest G935U Firmware QG1
My battery drain from 100%-15%...normally, but from 15% to 0% drain very fast. (5%/time: 15-10%-5%). and when 5% remaining it turn off suddenly.
My screen on about 4.5-5hous...
So Should I replace new battery? and how to fix or calibrate battery?
In my opinion the battery is ok

Before I paid for a new battery Id probably factory reset and see if it continues. Id also install accubattery from playstore. Youve got to let the app measure your battery health for 24 hours. Itll tell you how much battery capacity you have left (degradation)
But based on your observations, I'm not sure you need a new battery. Do you always let it run so low?

Battery Health in accubattery now is 96% after some charge times
15% remaining about 5mins using
hello,
I'm Italian.
Same problem for me since a week for my S7.
But I done the last update few monts ago (Android Nougat).
What we have to do?
Try an app called Advanced Repair Battery Life. You can find it on Play Store:
https://play.google.com/store/apps/details?id=com.mocamocaapps.advancedbatteryliferepair
Once installed, open the app and hit 'repair' and wait until the process is finished. Once finished, reboot your phone and see what happens.
I've used on my father's Sony device and it seems to work.
hello, an update.
without factory reset, without app.
On Monday, the battery is crashed from 14% to 1% in few seconds. Then a notification prompted me to correct the anomalous consumption of an app (it was whatsapp). I correct it and the it is remained turned on for 2 hour and half (without using) at 1%. Then it goes in auto turn off. Then I turned on and I wait that it goes in auto turn off. Then I plugged and I loaded battery to 100%. I think this procedure is called calibration.
The next days battery is not crashed, it has normal consumaption.
Today I will monitor what will happen.
thanks
Hi guys!
I got the same battery issues here.
Noted 2 days ago, it was at 15% remaining, talked 1 minute with my colleague and the S7 was turned off. Tried to turn it on, the battery was 0%, plugged in and recharged for a while.
Yesterday the same, at 15% turned off, then I monitored it and around 5/7% it switches off on its own.
From 15 to 5/7% goes very fast, in 1/2 minutes and not more. In this situation on the right side it becomes very hot.
I experienced a similar situation with my Galaxy Tab S, the screen was flickering and overheating issues with looping reboots. Solved by an unplug/replug of the internal battery.
I'm very worried about my S7E!
Just for note, I use Quick Charge very often and a magnetic support for car use.

Yesterday evening the same on my device. Spotify prompted as anomalous consumption, corrected and the drain stopped for a while.
Opened Tapatalk and here we go again with the fast running out. Hope that will be better right now.
Installed accubattery app, my battery has 72% of health.

Hi there.
I got this 2nd hand Note 3 (N9005) last week, and I'm testing battery life in different conditions with the original top update (5.0), before I flash a custom ROM and use it as my main phone.
System says battery is in good condition, and it has a fairly good standby time, but it drains quite fast (about 1% per minute) when active / SOT. GS monitor says I'm averaging 1h46m SOT, which I know is not good, and understandable since I guess this is the original battery.
Now the weird thing: I had about 13% battery when I turned it off. I removed the battery (I needed to take out the SIM card, I don't think this is related) but when I put the battery again in and turned it on, I had 35%!
I spent all of that until it has below 3%, it sounded the alarm and completely dimmed the screen and so, then I removed again the battery (checked also the contacts, nothing dirty on the battery or phone btw).
When I put again the battery, I got 18% power left. Now it's gone and I am afraid to play this game anymore - I'll just give it a full charge.
Does anyone experienced similar behavior? I wonder if it's a calibration problem, or a known symptom for old batteries.
As a side note, I had a Note 3 Neo Duos last year and the battery was bad. It used to discharge almost instantly from 30% to zero and turned off the phone. However I remember that I could remove and put again the battery for some extra life, just the same. I'm more or less terrified by this lol.
(The Neo Duos, N7502, was stuck at 4.3 without any development. I'm glad I was able to get this N9005 now).
I'm attaching a GS mon. screenshot showing usage so far, and the system Battery Use that shows the two points when I removed the battery.
Difficult to follow your post.
Suggest as first step Wipe Battery stats.bin.
Or from play store battery calibration app to wipe battery stats.
This will not calibrate battery just reset battery stats.
