Hello xda, I have problem with battery on my s3 mini. It says that phone is fully charged (100%), and when it reach about ~70% phone is rebooting, and after that it shows 0% and it is turning off. To complicate this problem more, if I plug into loader (while phone is off) it shows 70%.
I have stock rom, android 4.1.2, rooted of course. I have installed TWRP v18.104.22.168 and there is no battery wipe option. Do you have any ideas how to fix this ?
