How to Fix OnePlus 13 With Adaptive Battery Draining Quickly

The Adaptive Battery feature on your OnePlus 13 is designed to learn your usage habits and limit background activity for apps you rarely use. It helps extend battery life over time. However, some users have noticed the opposite: their battery drains faster instead of lasting longer.

If your Adaptive Battery is not performing as expected, it’s usually due to misconfigured settings, heavy app usage, or system-level issues. Here’s how to fix it.

Why Your OnePlus 13 Battery Might Be Draining Quickly

• Adaptive Battery is still learning your usage pattern.
• Power-hungry apps are running in the background.
• System or app updates are consuming resources.
• Battery optimization is turned off for key apps.
• High screen brightness or refresh rate is active for long periods.

Restart Your Phone.

Restarting clears temporary processes and resets background app activity, which often stabilizes battery performance.

1. Press and hold the Power key, and then tap Restart.
2. Wait for the device to reboot, then observe if the battery drain slows down.

This quick reset helps the system reallocate resources more efficiently.

Recalibrate Adaptive Battery.

Adaptive Battery works best when it has accurate usage data. Resetting it forces the system to relearn your usage pattern and improve prediction accuracy.

1. Open Settings, and then tap Battery.
2. Tap Adaptive Battery, turn it off, and wait a few minutes before turning it back on.

Continue using your phone normally for a few days to allow the system to rebuild its optimization data.

Identify and Restrict Power-Hungry Apps.

Some apps continue to drain power even when the screen is off. Identifying them helps you control background consumption.

1. Open Settings, and then tap Battery.
2. Tap Battery usage to view which apps use the most power.

If certain apps consume too much, tap them and restrict background activity. You can also uninstall unused apps to free up system resources.

Check Battery Optimization Settings.

Battery optimization prevents apps from running excessively in the background. If disabled for many apps, the system’s power management weakens.

1. Open Settings, and then tap Apps.
2. Tap Special access, then select Battery optimization.

Ensure most apps are set to Optimized or Restricted, especially those you rarely use.

Adjust Display Settings.

Your phone’s display consumes the most power. High brightness and refresh rates can drain the battery faster, especially on AMOLED screens.

1. Open Settings, and then tap Display.
2. Lower the brightness or enable Adaptive brightness, then reduce the refresh rate if possible.

This can instantly improve battery endurance without affecting daily use much.

Update System Software.

Software updates often include fixes for battery drain issues or background app management. Keeping your device updated ensures better performance.

1. Open Settings, and then tap System.
2. Tap System update, and then tap Check for updates.

Install any available updates, then restart your device afterward.

Reset All Settings.

If the issue persists, system misconfigurations may be affecting battery performance. Resetting settings restores everything to default without deleting personal data.

1. Open Settings, and then tap System.
2. Tap Reset options, then tap Reset all settings.

This will revert all power, display, and app settings to their original states, helping the system relearn and optimize battery performance.

A properly configured Adaptive Battery can make a big difference in how long your OnePlus 13 lasts throughout the day. Once you’ve applied these fixes, you should notice smoother performance and more efficient power usage.
