Do you think my iphone's battery usage seem to be normal?
I am using Iphone 13, battery health is 100% and telephone is 2 months old. My iPhone consumes 50% of battery in general within ~2h 50m of screen on and 15 minutes of screen off usage. However my friend's iPhone 13 consumes 55% of battery within ~6 hours of screen on and ~3 hours of screen off usage and his iPhone is 1 year old with 90% battery health.
I am a bit suspicious that my battery doesn't seem to work fine.
Please note: Background app refresh is off. Location services is 'never' for many apps and 'while using' for some of them. iOs version is 16.5.1. Auto-brightness is on. I have already visited iPhone Battery and Performance - Apple Support.
I have visited an Apple Reseller about the issue. They told me battery health is fine and if iPhone run out of battery fastly, it is probably because of 3rd party applications even if they are installed from AppStore. So my phone has been reset and I've installed only well known applications.
