Try some of these options too.

7. Manually lower brightness from Control Center
8. If you Want to watch continuous Video. Stream it on TV or a Monitor

iPhone Battery and Performance

Hello Harpreet,

Do not attempt to do switch batteries from iPhone to another. Each iPhone model has its own specification for a battery. The other thing that I do not understand is why would you switch a battery from a newer iPhone 11 to an older iPhone 6? Why not just use the iPhone 11?
