This has only happened only 2 times soo far in the last couple of months.


When i turn of my Samsung Galaxy Tab Pro 8.4 when it is under about 20 to 5% left of battery life.
And after i rebooted the Tablet the battery %(indicator) gone from 5/10% to 26% of battery life/charge with out even charging it!


What does this mean??? Is the battery indicator showing incorrect info? Has anyone had this before?



By the way i keep having problems charging the battery as the indicator keeps stopping while charging for some reason, it keeps stopping at any number 15%, 39%, 88%, 96% then i have to re plug the charger again(couple times sometimes) in order to charge again.....??


And i only getting 3/4 hours of sceen time instead of 5 hours of SOT on a single charge on battery despite having all of the things like GPS, WIFI, Bluetooth, Multi Window off and having the brightness set under 30% and having CPU power saving mode on and force closing RAM hungry apps(Google Chrome, Youtube, etc) on GSAM Battery monitor and it is still CRAP!!!!

And Is there anything else that i can do to improve the battery life?

I'd say it is faulty and i would return or pass it on. I am a serial device changer (in rehab) and i had an Asus Transformer pad with this issue.

Full battery drain till in conked out, apps to 'reset' the fault. Nothing helped so i returned it.

Samsung? I had a Tab4 and although it was SUPER laggy the battery was great. Around 9+ hours screen time.

i got fed up with the lag and got rid. Plus despite being a 2014 model it was stuck on android 4.4.4...

That is partly normal for many devices. The battery indicator tends to use a mix of phone usage and available capacity, to measure how much you have left, AFAIK.

I've seen it on every device I have owned, you do a reboot especially after heavy use and it will jump 1-5% from what it was.

WRT to the indicator getting stuck, that sounds like either a firmware bug or dud battery.

I believe they use a voltage reading from the battery to estimate the charge. It's not a completely accurate thing, so generally it's seen as an estimate (a decently good one most of the time, but can have fluctuations if the battery isn't that great, or some other variables involved).

Exactly this from what I understand.

I remember the old Sony Ericsson phones, if you used it heavily for like 30mins straight the battery indicator would drop by around 5%, then leave the phone alone for like 15mins and after that pick it again and the battery level would be higher by around 2-3%. Happened on my W800, W900 and K850i.
