iPhone 13 battery
My iPhone 13 just arrive 2 days ago and I was testing its battery life I noticed that my battery went from 37% to 34% overnight is this normal or it drains to much battery? I have my background app refresh turned off as well as my haptics. I used my iPhone throughout the day with cellular data on, last plugged in 100% at 1630H and checked it 34% at 0830H. All replies are much appreciated.
iPhone 13, iOS 15
