Did you check which apps are using your battery life the most in Settings/Battery?
Try to reset the iPhone to factory settings, to rule out, that the iOS software caused the issue.
To rule out defective data from the backup, set it up as a new device and test the battery life again.
Restore your iPhone, iPad, or iPod to factory settings using a computer - Apple Support
If it is back to normal, restore from the latest backup again.
Yes I checked but it seems like they all on screen n whenever and I don’t have background apps using any battery, so I don’t know what’s up with the phone .. but try factory resetting hopefully it’ll work I literally used every tip I could find on battery life but they don’t really work ..I thought the fact that the phone is new has some kind of impact on the battery life but I’m not so sure anymore ,72. Hours done passed already but still no improvement
