I know there are similar topics but I thought I poll maybe helpful to quantify what the differences are in battery between the 12 pro and 13 pro. Commentary always great!!
Assumptions = everyone is medium to heavy user
This. I have owned iPhones for 14 years and never had one that could last a full day of very heavy usage (granted I have never owned Plus or Max models) but I cannot kill this 13 Pro Max in a single day of use no matter what I am doing with it, it’s insane.
