Part 1: Potential Reasons for Quick Battery Drain in iOS 16 on iPhone/iPad

“Why is my iPhone battery draining so fast?”

After an iOS update, the iPhone battery dying quickly, is not uncommon but usually takes place within 48 hours. If you've just updated (or restored) your iPhone and notice that your battery isn't lasting as long as it used to, don't panic. You can use it for a few days and then check again. If your battery drains much more quickly after a few days, it may be time to contact Samsung Support to solve the issue.

The battery draining on iPhone could be due to a software problem or underlying hardware issue on your iPhone. Software issues could be a faulty app that regularly demands extensive system resources. It could also be due to some bugs in the operating system. Another reason you may be experiencing the battery drain issue is your iPhone's reduced battery life. However, some situations can accelerate battery aging. These include concurrently charging the battery, using the device in high temperatures, or charging the device after extreme battery depletion. Now that you have more information on battery drain, let's explore solutions to fix it.

Part 2: Pro Tips to Fix Battery Drain Issue in iOS 16

After installing the iOS 16 beta on your iPhone, do you feel battery life is worsening? Battery draining issues are not uncommon after significant system software updates, and the iOS 16 beta is no exception. Fortunately, there's usually a reason for these battery performance issues and solutions. Installing the iOS 16 beta goes without a hitch for most users, but for others, there can be trouble and difficulty. Battery issues are the most common complaints.

Here are pro tips on how to fix it!

Method 1: Restart Your iPhone

restart iphone

If you begin to experience excessive battery draining on your iPhone while using the iOS 15 beta, we recommend restarting your iPhone by visiting Settings > General > Shut Down. If a simple restart doesn't resolve the iOS 16 beta battery drain issue, perform a Force Restart.

Force restarting your device can clear errors and resolve the iOS 16 battery drain issue. For this, press and release the Volume Up, Volume Down, and Side buttons until you see the Apple logo on the screen.

Method 2: Turn Down Device Brightness

You can quickly crank up the screen brightness in a bright room or in direct sunlight, but if you don't need a super bright display, dimming it can save iOS 16 battery life. Set the brightness in the iPhone's Control Center using the brightness toggle or the Display & Brightness section of Settings.

It's usually a good idea to activate the auto brightness setting to ensure that your screen isn't too bright in darker rooms by default. But manual adjustment may be necessary for more colorful rooms and the sun.

Method 3: Install the Latest iOS 16 Beta

Apple will release new iOS 16 beta software periodically. While the company may not mention battery-life fixes in the change log, new beta software has the potential to help address these problems. Upgrade to the latest version if your iPhone runs the old iOS 16 beta software.

Method 4: Adjust Auto-Lock and Turn Off Raise to Wake

If you are still experiencing the iOS 16 battery drain issue, you might consider setting the Auto-Lock on display as low as you can tolerate. This will cause the iPhone's display to turn off after a short period of inactivity. You can choose a time range from 30 seconds to never, but the lower end of the spectrum will help to prolong battery life by shutting down the display when it is not needed.

Switching off Raise to Wake can also be beneficial if you are trying to save your iOS 16 beta battery. These options are in Settings > Display & Brightness.

Method 5: Use Dark Mode

Even though some users might naturally prefer a darker interface, it can help solve the iOS 16 beta iPhone battery draining quickly, primarily because the display will only light up the required pixels, the rest automatically off unless needed. You can enable it by selecting Dark from the Display & Brightness option in Settings.

Method 6: Enable Reduce Motion of Interface

The Reduce Motion function on iOS has always been incredibly helpful in preserving battery life in iOS 16 beta; the option turns off animations and keeps battery life at a lower risk. It can be enabled by clicking Settings > Accessibility > Motion, then turning off Reduce Motion.

Method 7: Disable Background App Refresh

When dealing with why is my iPhone battery draining so fast problem caused by the iOS 16 beta, you will want to disable Background App Refresh. Background App Refresh can slow battery performance, so turning it off can help your battery last longer.

Turn off background app refresh from Settings > General > Background app Refresh and switch off the option.

Method 8: Turn off Automatic Downloads and App Updates

The automatic downloads feature helps sync apps between your devices by transferring apps you have downloaded on one device to all of them. If you download an app on an iPad, Automatic Download will also move the app to your iPhone, which could make your iOS 16 beta battery draining worse on your iPhone.

You can turn off this feature by selecting Settings > App Store and then turning off Apps and App Updates.

Method 9: Place iPhone Face Down

When you receive a message or any other notification on your iPhone, its display lights up for a moment to alert you and wastes too much energy. But there's a simple way to avoid it and improve battery usage on iPhone. Put the iPhone facing down when not in use, and the device will detect this position automatically and not flash the display when alerts are received, saving you some battery life.
