Battery like became a lot more better on iOS 15.1! Very satisfied with how it drained over a full work day with 4G connection for almost 9 hours straight.
Unplugged the phone from the charger around 12am on Thursday and I got 2.5 hours of SoT with 25% of battery used. Amazing. For those who’re contemplating to switch from an 11 or 11 Pro to the 13 Pro series just for the battery life, consider changing the battery of your older iPhone instead.
