I have the same problem. This is the 2nd time I have my battery replaced. I didn't pay attention that the 1st time the battery didn't hold charge well. The 2nd time I did. They replaced it again and the same problem. At this point, I was told the issue is with the phone itself.
Fully charged, everything that could be disabled off, it drains 30% of the battery overnight, leaving me with 70% in the morning.
On top of this, this is the 2nd samsung phone I have in a row that periodically won't take or make calls, and I need to toggle the VoLTE SIM 1 switch to make it work. The N9 and N20U5g. My husband has the same model and has no such issues. I'm a long-time Samsung user, not just phones. But... I have a 40yo S dual cassette radio that works like brand new. What gives?
