Extending iPhone 8 Plus Battery Life without a Battery Case

If you’re not ready to invest in a battery case just yet, there are still several ways to extend your iPhone 8 Plus battery life without the need for an additional accessory. Here are some tips and tricks to help you make the most out of your device’s battery.

Optimize Display Settings

Dimming the screen brightness and reducing the screen timeout duration can significantly impact battery life. Adjust your display settings to strike a balance between readability and power consumption.

Disable Background App Refresh

Background App Refresh allows apps to update their content even when you’re not actively using them. Disabling this feature for apps that don’t require constant updates can save precious battery life.

Manage Location Services

Location Services can be a battery drainer, especially when multiple apps have access to your location. Review and disable location access for apps that don’t necessarily need it, or set them to use location only when the app is in use.

Reduce Push Email Frequency

Push email constantly checks for new messages, consuming battery power in the process. Adjust your email settings to fetch emails at longer intervals or manually check for new messages to conserve battery life.

Limit Background App Activity

Some apps continue running in the background, consuming battery life even when not in use. Close unnecessary apps and prevent them from running in the background to maximize battery efficiency.

Turn off Unnecessary Notifications

Notifications from various apps can be distracting and drain your battery. Disable notifications for apps that are not critical or limit them to only the most important ones.

Enable Low Power Mode

Enabling Low Power Mode on your iPhone 8 Plus is an effective way to conserve battery life. This feature adjusts various settings, such as reducing screen brightness and disabling background app refresh, to extend the usage time of your device.

Close Unused Apps

Running multiple apps simultaneously can drain your battery quickly. Make it a habit to close unused apps by swiping up from the bottom of the screen and swiping away the app windows. This ensures that they are not running in the background and consuming unnecessary battery power.

Use Wi-Fi Instead of Cellular Data

When available, connect to a Wi-Fi network instead of relying solely on cellular data. Using Wi-Fi consumes less power compared to using mobile data, as the phone doesn’t have to work as hard to maintain a stable connection.

Disable Push Notifications

Push notifications from various apps can be a constant source of battery drain. Consider disabling push notifications for apps that are not essential or limit them to only the most important ones. This reduces the frequency at which your phone wakes up and checks for new notifications.

Limit Background App Refresh

Background App Refresh enables apps to update their content in the background, but it can consume a significant amount of battery power. Go to Settings, select General, and then Background App Refresh. From there, you can choose to disable the feature altogether or customize it for specific apps.

Reduce Motion and Animation Effects

The dynamic motion and animation effects on your iPhone may look impressive, but they also contribute to battery drain. To conserve battery life, go to Settings, select Accessibility, and then Motion. Toggle on the Reduce Motion option to minimize these effects.

Keep Your Software Up to Date

Regularly updating your iPhone’s software is essential for optimizing battery performance. Software updates often include bug fixes and improvements that can result in better battery efficiency. Check for updates regularly by going to Settings, selecting General, and then Software Update.

Monitor Battery Usage

Keep track of which apps and features are consuming the most battery power on your iPhone 8 Plus. Go to Settings, select Battery, and then Battery Usage. This will provide you with insights into the apps that are draining your battery the most, allowing you to make necessary adjustments or limit their usage.

Troubleshooting Common Issues with iPhone 8 Plus Battery Cases

Encountering issues with your iPhone 8 Plus battery case can be frustrating. Here are some common problems you may face and troubleshooting solutions to help you resolve them.

Case Not Charging

If your battery case is not charging, check the connection between the case and the charging cable. Ensure that the cable is securely plugged into both the case and the power source. If the issue persists, try using a different charging cable or power adapter to identify if the problem lies with the accessories.

Insufficient Battery Life

If you find that your battery case is not providing the expected battery life, consider recalibrating it. To do this, fully charge your case, then use it until it completely drains. Repeat this charging and discharging cycle a few times to recalibrate the battery capacity. If the issue persists, contact the manufacturer for further assistance.


If your iPhone 8 Plus battery case is overheating, remove it from your phone immediately and allow it to cool down. Overheating can be caused by excessive usage or a defective battery case.

If you notice a significant decrease in signal or audio performance when using the case, try removing it and see if the issue resolves.
