My Tab S2 gets very hot during normal usage. The hotspot is about two-thirds up, on the right hand side (when looking at the screen). The battery life has also shortened significantly, draining in half a day instead of the usual 3 to 4 days. When the battery gets under 20% it sometimes reboots itself. It never used to be like this - one day it was my favourite device and since then it's been disappointingly underperforming.
I assumed it was a battery problem on my unit when I stumbled on this following Samsung US thread 'Galaxy Tab S2 drains battery after recent update':
A number of users there have reported identical issues, apparently all starting around June 2017 when there was a system software update.
Following the advice, I have attempted a factory reset and tried Safe Mode. The issue persists. All my apps are up to date. I'm using 12.2GB of the available 32GB and charging with the undamaged supplied charger. I have cleared the cache partition (http://www.samsung.com/uk/support/mobile-devices/my-device-is-charging-slowly-not-switching-on-or-keeps-restarting/). The unit still gets extremely hot and the battery runs itself down.
Can anyone advise? Is there a possible fix? Is there a way to downgrade to a previous version?
Thanks in advance.
