I improved my iPhone's battery life by changing these 10 settings
Briefly

One of the biggest power drainers on the iPhone Pro series is the always-on display, sipping about 1% per hour, impacting battery life significantly. Turning it off under Settings > Display & Brightness > Always On Display can preserve battery power.
Disabling haptic feedback while typing on the iPhone can reduce unnecessary battery drain caused by constant vibrations. Turning off this feature under Settings > Sounds & Haptics > Keyboard Feedback can help extend battery life.
