Tip 2. Update iOS to Latest Version

The first thing you should check when the iPhone 7 Plus battery draining fast in iOS 13 is if another update has been released. You might have upgraded to the old version of iOS 13, which is leading to this issue. So, you simply need to update the iOS.

  1. 1. Open Settings > General > Software Update and check for the latest updates.

  2. 2. If the update is available, then click on the “Download and Install” option. After installation, restart the device to make sure that the updates are installed correctly.

Tip 3. Check and Manage Battery Usage on your iPhone

If there is no update and you still can’t understand why the battery on iPhone 7 Plus draining fast, then review the battery usage. Check if there is a particular application that is draining the battery entirely. The Battery Usage feature of iOS will help you track down the app that is the cause of this problem.

Open Settings > Battery and select the Battery Usage by App option on the menu. Under this option, you will see the amount of battery consumed by each application installed on the device.

Use the information displayed to diagnose the battery drain issues and resolve them accordingly. You might have to delete some apps which are not important, still consume the battery in the background.

Tip 4. Lower Down the Screen Brightness

You need to understand that every setting inside the iPhone affects its performance somehow. And screen brightness is one of those settings. If the iPhone 7 Plus battery is draining quickly, then you should enable the Auto-Brightness mode and let the device adjust the screen brightness automatically. This will save battery by reducing the brightness when you are not using the device.

Tip 5. Turn Off Wi-Fi & Bluetooth When Not in Use

Many users leave Wi-Fi and Bluetooth on so that it will connect automatically to previously paired devices. But this isn’t something that we recommend if you are facing iPhone 7 Plus battery issues. It will be better if you keep the features off when they are not in use to save a significant amount of battery.

Open the Control Center and tap on Bluetooth and Wi-Fi icons to turn them off. You will automatically notice that the battery isn’t draining as quickly as before.

Tip 6. Disable Background App Refresh

If the iPhone 7 Plus battery is draining faster, then you should also check the Background App Refresh. All iPhone and iPad have a feature called Background App Refresh Mode that keeps on refreshing the apps running in the background. But this mode has a negative impact on battery life. Hence, to resolve one of the factors that are draining the battery faster than usual is this mode. To disable this mode, follow the steps below.

Open Settings > General > Background App Refresh and toggle the bar to turn it off.

This will make sure that the background apps don’t consume the battery anymore.

Tip 7. Disable Location Services

Another setting that might be causing the iPhone 7 Plus battery drain quicker is location services. Disabling this feature will prevent GPS from consuming battery unnecessarily.

Open Settings> Privacy > Location Services, and switch the location access to “Never” or “While Using the App.”

This will make sure that the feature is active when the user needs; otherwise, it stays inactive.

Tip 8. Turn Off Automatic Downloads in iTunes & App Store

We often keep the update settings automatic when it comes to the apps installed on the device. You don’t see the apps updating, but the feature is active in the background. As a result, the iPhone 7 Plus battery drains too fast. Hence, we need to switch off the feature.

Go to Settings > Your Apple ID> iTunes & App Store, and you will see the Automatic Downloads option in the menu.

Toggle the bar to turn off the feature, and from now on, update the apps manually whenever you need to.

Tip 9. Turn on Low Power Mode

Some users can’t figure out the exact reason for battery issues. So, instead of asking, “why is my iPhone 7 Plus battery draining so fast” on every forum site, we suggest that you use the Low Power Mode. This mode will come in handy if you have a low battery percentage left on your device and no other way to charge your iPhone.

Launch Settings > Battery, and you will see the Low Power Mode option. Enable this mode, and you’ll no longer have to worry about making your iPhone’s battery last for more than a couple of hours.

  1. 1. Go to the Settings app and open General Settings. Scroll down to look for the Reset option.
