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?
Well the reason is listed in your screenshot: bad signal while Mail was active or worked in the background.
Nothing kills the battery more than bad cell reception, as the phone has to put more effort and therefore energy into upholding communication.
As most of your consumption seems to be while the screen is off turn off background refresh for mail to A/B test if power drain goes back to normal levels. Alternatively dial back how often Mail should fetch new mail.
I have 5G Signal in these Area and good wifi Signal at home. This can‘t be the reason.
Personally iOS seldomly betrayed me with it’s judgement regarding battery drain and the possible root cause. 🤷♂️ And there still is a difference between 5G with four signal bars and 5G with one. Not all 5Gs are built the same.
You can choose to ignore iOS analysis, but I think you would do yourself a disservice. That should be the first thing to debunk/confirm from a debugging perspective.
