iPhone 15 Pro Max charging speed

Your iPhone 15 Pro Max is a very advanced device when it controls charging. Please remember you can only see the on screen indicator but the phone's internal charging control logic can talk to the battery and determine parameters like battery temperature, power available and how much is diverted to other tasks, and any optimised charging requirements. Even something like a recent long phone call could raise the battery temperature enough to change the charging process.

The variable charging time you have observed is based on only 3 records. I think you need more tests to get a more accurate and detailed picture.

Hey Labor_MJ,

We'll be happy to help out with this question. Depending on the apps and processes running at the time of charging, it could be the reason that charging times vary. Also to ensure optimal charging, clean any lint or debris from the iPhone charging port:
