Battery drain and poor SOT for the last 2 weeks

[Nakuro]

Since that problem occurred there has been one software update which didn't fix the issue. The battery was solid before that. A very disappointing purchase! It can barely last for 4 hours of SOT these days and that's when being connected to WiFi 90% of the time. Imagine if I was on 5G .Most of the time. As you can see on the screenshots - nothing out of the ordinary is consuming a lot of power.3 weeks before the problem, I used to get at least 6 solid hours of SOT.
