10 Check Your Battery Usage
When you notice your iPhone’s battery draining very fast, one of the first things you should do is check the battery usage to determine which apps are consuming the most battery power.
- Go to Settings.
- Tap Battery, and there you’ll find a list of apps along with their battery usage in the past 24 hours and the last 7 days.
- If an app consumes a high amount of battery power, then you should always close it from the App Switcher whenever you don’t need it, rather than keeping it open in the background.
