Since the release of iOS 16, many iPhone owners have reported power drain issues. If you are experiencing this problem, there are a few steps you can try to resolve it. One of the first things you should do is check the battery health of your iPhone. To do this, follow these steps:

Launch the Settings app.
Tap Battery.
Select Battery Health. The Battery Health section will show you your battery’s current maximum capacity. If your battery is less than 80% charged, this could be the cause of your battery depletion problem.

7. Use the Auto-brightness feature

If you are experiencing battery drain issues after upgrading to iOS 16, you may want to consider turning on auto-brightness to help conserve battery life. This feature automatically adjusts the brightness of your screen based on the surrounding lighting. To enable auto-brightness, follow these steps:

Go to Settings.
Tap Accessibility.
Select Display & Text Size.
Scroll down, select Auto-Brightness, then flip the switch to ON.

8. Turn off Raise to wake

Some users may be experiencing battery drain issues due to a specific feature. “Raise to wake” is a feature that allows your iPhone to wake up when you lift it. While this can be a useful feature, some users have reported battery drain issues as a result. If you are experiencing battery drain issues with iOS 16, you may want to try turning off Raise to wake. To do this, follow these steps:

Open Settings.
Select Display & Brightness.
Toggle off the Raise to Wake feature by finding the entry and scrolling down to locate it.

This may help resolve your battery drain issues with iOS 16.

9. Deactivate background app refresh

A feature called Background App Refresh allows apps to update when not in use, which can consume battery power. To prevent this behavior, you can disable the Background App Refresh feature on your iPhone. To do this, follow these steps:

Go to Settings > General > Background App Refresh.
Turn off the feature by toggling it off.

When this feature is disabled, apps may take an extra second or so to update, but most users will not notice a difference. However, you may notice an improvement in battery life.

10. Use Low Power Mode

Low Power Mode is a useful feature for increasing battery life on the iPhone by pausing background activities and other processes. This can be particularly useful when you are out and about and trying to extend the battery life of your iPhone, as it can also pause tasks that may eventually allow your battery life to return to normal (such as indexing tasks). To enable Low Power Mode, follow these steps:

Go to Settings > Battery > Low Power Mode.
Toggle the feature on.

This will help you conserve battery life on your iPhone.
