I’ve had an iPhone 15 Pro Max since October 2023. I’m happy with it and would like to use it for a few more years.
One thing bothers me a lot. The battery consumption of the apps and the fact that it keeps freezing and getting really hot.
According to the check, the battery is in normal condition and at 84%.
The memory is only half full.
What could be the reason for this?

Not really. Two times these day.
