Reducing the time for the display to turn off
The iPhone display is one of the components with the largest power consumption. The longer it lights up, the more energy it consumes. By reducing the amount of time the screen is on when you're not actively using it, you can save a significant amount of battery power. This is especially useful if you frequently check notifications or the time, but don't necessarily interact with the phone for long periods of time. You can adjust the time for the display to turn off in Settings -> Display & Brightness -> Lock.
Disable background app updates
One of the lesser-known features that can drain your iPhone's battery is the background app update feature. This feature allows apps to update content in the background while connected to Wi-Fi or mobile data. It's convenient, but it can significantly affect battery performance.
