hello there i have blackberry z10 mobile
from last few days i am facing a problem that my phone is getting switche off
although it is providing a good back up.
the phone battery indicator is mis matched with real battery level
therefore it is showing >50 % of battery as always even though i got switched off without any pmompt
pls help me find how to re synchronize the battery indicator to its actual value.

i have already done firmware update, factory reset and security wipe
still facing the same issue
pls help
