Z2- Battery percentage problem

[nicholasman]

Hi everybody. I would be glad if someone can help me with this problem.

My phone is Sony Z2 and its battery is crazy. sometimes the battery persentenge drop from 100% to 1 % in few mins and sometimes it stops in 1% for 24 hours or more. I changed the battery and problem still exists. what should i DO ?

you probably need a new battery but it'll be wise to first back up and repair your phone with XC
