If you talk about this, it's just a estimate... what's your SOT?
22 % battery drain in just 56 min of usage (only chatting on whatsapp and telegram ) and what is SOT?
SOT = screen on time
So that would give you 4-5 hrs of sot on a full charge... not great, not terrible
it'll not if i play pubg for an hour
It's bad.. really bad.
And yes.. this is happening for many users along with some heating issues too.
This started happening after the 10.3.2 update.
I would say, submit a feedback and a bug report to the Developers on the Forum. Let them know about this issue and do send the system logs and some relavant Screen shots too, like in this thread.
