Hi all,
I am facing some battery issues for a month now. It dropped suddenly from 3 days autonomy to 20 hours and can't finf the reason.
Tests I did
0) Identify apps consuming battery (google service and so on...). Did many changes but at the end same problem.
1) Update from B521 to B860 (OTA)
From now on, all tests are donr without any additionnal applications
2) Wipe cache + wipe data
3) Downgrade to B521 (first B800 then B521)
4) Test in stand-by mode. Still having the issue! This is wierd to me. Battery drains exactly the same with phone in stand-by mode or not!
5) Test with different SIM cards
6) Test forcing 3G/2G (no 4G). A bit better (about 1 day without using the phone)
8) Test without SIM nor google account connected... same issue
Any ideas?
