Around 3 weeks ago I noticed my phone's battery being dead in the morning despite leaving plenty of battery left in the evening. In the past week I've been experimenting with different settings and removing certain apps, but nothing has helped. I even factory reset the phone and still the battery drains just like before. It feels as if the battery drains at the same pace whether the screen is on or off.
I have the power saving mode constantly on, mobile data and location off, super saving for 6 hours of the night and still the battery drains over 50 % overnight. What could be causing this and is there anything to do other than take it back on warranty?
