Please try my methods if you want to conserve more battery/prevent overheat
- Set graphics to fastest, lowest setting.
- Set the low power mode to ON (in your phone and in this game’s setting).
- Set the SFX to off during cruise
- Turn the brightness to to the lowest setting possible.
- Turn on the night shift and dark mode.
- Place them on an well-conditioned room possible, even during charging (placing your phone in front of a fan is OK too).
During flight, you should not touch the phone during a cruising (wait until you reached the top of descent).
You may have to buy a newer model every 3-4 years (not everyone can do this, so use this setting to conserve as much battery as possible and to prevent overheat).
