Okay, 15 Pro 256GB user here again. This is my 10th day with the phone, and I encountered a serious battery drain problem last night. I put the phone into low power mode at 1:24 AM when the battery level was 43%. When I woke up at 8:39 AM, it was down to 25%. I had experienced some mild overheating and battery drain issues in the first 3 days, but everything seemed to be going well until last night. I have never encountered such a serious battery issue in the past 10 days.
And please don't tell me the phone is in emergency mode and the battery is draining rapidly because it's searching for networks. I haven't introduced any e-SIM to the phone since the day I opened the box, so the test conditions haven't changed during that time


If this happens again. I'm returning the phone.
