2. Keep sufficient memory running in the background, and remove unnecessary applications at the background.
3. Please keep the phone screen light on.
4. Turn off the power saving mode, path: Settings > Battery > Power saving mode.
5. Long press the app > tap App Info > Battery usage > Turn On Allow foreground activity, Allow background activity, Allow auto-launch.
If the above methods do not solve your problem, please back up your data and visit the nearest authorized realme service center for testing.
