Sony Xperia 1 VI battery drain

Hi guys I have been using my Sony Xperia 1 vi phone for 5 months and I have to say that the battery life has been pretty disappointing. I get ~3hours of Sot with very light use (phone calls,Spotify,social media,YouTube and no gaming, heavy editing) and my battery drop from 90 to around 35%. Currently I run Android 15 version 69.1.A.2.100 and things are getting worse.

My phone settings are: 1) Adaptive brightness is off 2) High refresh rate on 3) 5g off, only 4g is allowed 4) Battery care is on at 90% 5) Apps have been monitored using Accubattery and gsam battery and I didn't notice anything strange

I have noticed that: a)During phone calls the battery drop like 8% for a 30 minute phonecall b)when using social media the phone drops really fast c) when browsing using chrome battery also drops unexpectedly fast d) CPU battery usage is pretty high without any heavy tasks

Additionally I have noticed that battery usage in settings does not work at all and all the metrics are not trustworthy.

Do you have any suggestions that could help? Is it possible that any rogue app is running in the background;
