When Power Saving Mode is not working on your OnePlus 15, the battery may drain faster than expected even though the feature appears to be enabled. This can be frustrating, especially when you rely on it to get through long days. In most cases, the problem is caused by conflicting settings, background app behavior, or system restrictions that prevent the mode from working as intended.
Why Power Saving Mode Is Not Working on Your OnePlus 15
- Power Saving Mode is enabled but overridden by performance or battery optimization settings.
- Certain apps are exempt from battery restrictions and continue running in the background.
- System cache or temporary bugs are preventing the feature from activating properly.
- Battery usage settings are misconfigured after a software update.
- The phone is plugged in or recently unplugged, which can delay Power Saving Mode behavior.
1. Turn Power Saving Mode Off and Back On
Power Saving Mode may appear active but not fully apply its restrictions. Toggling it refreshes the system rules and forces the phone to reapply battery limits.
Open Settings, and then tap Battery.
Tap Power Saving Mode, turn it off, and then turn it back on after a few seconds.
2. Check Battery Optimization for Apps
Some apps are allowed to ignore Power Saving Mode. These apps can keep running in the background and drain the battery even when the feature is enabled.
Open Settings, and then tap Battery.
Tap App battery management, and review apps set to run without restrictions.
3. Disable Performance or High Performance Mode
Performance modes prioritize speed and responsiveness over battery life. When enabled, they can limit or cancel the effects of Power Saving Mode.
Open Settings, and then tap Battery.
Tap Performance mode, and make sure it is turned off.
4. Restart Your OnePlus 15
A restart clears temporary system glitches that may prevent Power Saving Mode from working properly. This step often resolves issues that appear after long uptime or minor software errors.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up fully before testing Power Saving Mode again.
5. Check Background Activity Restrictions
Power Saving Mode relies on background limits to reduce battery drain. If background activity is unrestricted, the feature cannot work as expected.
Open Settings, and then tap Apps.
Select an app, tap Battery usage, and choose Restricted if available.
6. Update the System Software
Power Saving Mode issues can be caused by bugs in the current software version. Installing updates ensures battery features work as intended.
Open Settings, and then tap About device.
Tap Software update, and install any available updates.
Power Saving Mode on the OnePlus 15 is designed to automatically reduce background activity, limit performance, and extend battery life. Once conflicting settings are removed and the system refreshes, the feature should start working consistently again.
