For a few months, my iPhone 8 has been acting strange
It's been freezing, lagging, and responding slow. About once a day, the phone becomes really slow, to the point of being unusable. This lasts about thirty seconds. During this time, the phone heats up quite a bit, and the battery drains a lot faster than normal. It often happens while opening the app menu (double click home button) or after exiting Safari.
In addition to this problem, my phone's battery drains really fast when using certain apps. When browsing Safari, my phone can lose 5-10% in a minute.
Another example of this is when recording video. The phone's battery drains ridiculously fast (just like above) and the phone often gets hot to the point where the flash becomes unavailable.
A final example is the DJI Fly app. When flying my drone and connected to the controller, I get at most 30-45 minutes of time before my phone drops from 100% to 10%. The phone also heats up quite a bit during this time.
I checked the battery health - it still has plenty left, 67%.
Safari has no tabs open.
Attempted troubleshooting:
- Turned off Bluetooth and WiFi - No effect
- Turned on Low Power Mode - No effect, battery sometimes drains faster
- Turned down screen brightness - Slight effect, not much
- Turned off Location - The battery lasts about twice as long while using the phone normally, but does not affect the rapid overheat/drain while using certain apps.
- Restarted the phone - The phone dropped 15% while restarting, no effect afterward
- Charging the phone - The phone doesn't heat up as much, and the battery lasts longer. Some apps still drain the battery faster than it can charge, and the percentage goes down anyway.
