Sorry.. New user of this phone... Bought from a forummer.
I just want to know...
How's the phone battery life when using stock rom and with custom one? Feels like the battery drains like crazy even when im using the phone lightly.

From 90% on 12:19 to 77% on 12:39...
Running whatsapp on background.. On mobile data (H), no wifi..

Is this considered normal or not?
