If your OnePlus 15 battery seems to drain faster after Adaptive Battery is enabled, you are not alone. This feature is designed to learn your usage habits, but during certain conditions it can cause unexpected battery loss instead of saving power. The issue is usually tied to app behavior, background activity, or system optimization delays, and it can be fixed with a few targeted adjustments.
Why Adaptive Battery Is Draining Your OnePlus 15 Quickly
- Adaptive Battery is still learning your usage patterns.
- Certain apps are excluded from optimization and run constantly.
- Background activity and syncing are not properly restricted.
- Recent system updates temporarily increased power usage.
- Location, connectivity, or refresh features are running aggressively.
Review Adaptive Battery App Usage
Adaptive Battery works by learning which apps you use the most and limiting the rest. If certain apps are misclassified, they may continue running in the background and drain power.
Open Settings, and then tap Battery.
Tap Adaptive Battery, and review the list of apps being optimized.
If an app shows heavy usage, restrict it manually to prevent constant background activity.
Limit Background Activity for Problem Apps
Some apps continue syncing or refreshing even when Adaptive Battery is enabled. Manually restricting them gives you more control over power usage.
Open Settings, and then tap Apps.
Tap the app that is draining battery, and then tap Battery usage.
Select Restrict to limit its background activity.
Turn Off Unnecessary Connectivity Features
Wireless features constantly searching for connections can drain battery faster than expected. This is especially noticeable when Adaptive Battery is active.
Open Settings, and then tap Wi Fi and network.
Turn off Wi Fi scanning or Bluetooth scanning if you are not using them.
Check battery usage again after a few hours.
Check Location Usage
Location services can override Adaptive Battery restrictions. Apps that frequently request location access can cause rapid battery drain.
Open Settings, and then tap Location.
Tap App location permissions, and review which apps have Always allowed access.
Change them to Allow only while using the app when possible.
Restart the Phone After Enabling Adaptive Battery
Adaptive Battery sometimes needs a clean restart to apply its optimizations properly. This step refreshes system processes that may be stuck.
Open Settings, and then tap Power options.
Tap Restart, and wait for the phone to reboot completely.
Use the phone normally and monitor battery performance.
Temporarily Disable Adaptive Battery
If battery drain continues, disabling Adaptive Battery for a short period can help reset its learning process. You can enable it again later once usage stabilizes.
Open Settings, and then tap Battery.
Tap Adaptive Battery, and turn it off.
Use the phone for a day, then turn it back on to allow fresh optimization.
Adaptive Battery can be helpful, but it works best when paired with proper app and system management. Once you limit problematic apps and unnecessary background activity, your OnePlus 15 should return to normal battery performance.
FAQs
Why does Adaptive Battery drain more battery at first?
Adaptive Battery needs time to learn your usage habits. During this learning phase, battery consumption can temporarily increase.
Should I leave Adaptive Battery on all the time?
Yes, once it finishes learning and problematic apps are restricted, it usually improves battery life rather than reducing it.
How long does Adaptive Battery take to optimize properly?
Most users notice improvements after a few days of regular use, once the system finishes analyzing app behavior.
