I just started using my new S21 Ultra, and the battery is draining super fast with regular use. Today the battery is down from 100% to 25% in under 6hours! Also running a bit hot for no obvious reason?! The battery app says that full charge should last 50 hours?! Now it looks like it might only last about 8 hours, which is totally not enough to use this phone at all! Makes it totally unusable!
Just updated phone last night and started from 100% battery this morning. I have a top end phone, I don't want to limit CPU speed 70% or limit screen from adaptive 120 Hz to 60 Hz, as those are some of the features of the phone, and it would feel silly to spend extravagant amount of money for specifications that I can't use, or that I would need to downgrade in order to use the phone..
