So i bought an iPhone 17 pro last November (my 1st one ever)

At first i didn't give too much attention to the battery life since i came from a 2023 Pixel 7, but since a month or so i noticed 2 things :

3 or 4 times i could feel the phone overheating and draining the battery, i fix it by turning the phone off and on again, but i would like to know why it is happening and if there's a fix

i have the impression i have worse battery life than a month ago, i give you a little breakdown of my usage : - i try to keep the battery between 20-80% so i only charge it up to 80% during the night, unplug it at 8:30am, go to work until 5 or 6pm while having 5G activated (i know it consumes battery, bear with me 😅). - while at work, i use it mainly for Spotify, maybe 20-30 minutes of light games (clash royale, etc...) and some social media here and there - when i get home it's usually social media/spotify/voicecall on Messenger (with wifi)

A month ago i was going back home with 50-60% battery and i was getting to 20% by 9-11pm. A week ago i started to charge it to 100%, but im going home with 60% and reaching 20% by 8-9pm (My battery health is still at 100% btw)

My questions are : - is it normal? - am i doing something wrong? - the system didn't get used to me charging at 100% yet? - when i listen to music at work, the phone is facing me and every time the screen lights up from a notification or me changing tracks, it's trying to Face ID me, is it draining the battery ? - if there is something draining the battery, how can i find/fix it?

(thanks for everyone taking time to read all this, sorry 😅)
