Understand the limitation first
Background recording on Android is possible, but it is still affected by OEM battery policies and background task restrictions.
MultiHR can keep recording more reliably when the phone allows the app to keep its foreground activity and notification state visible.
Check the key settings before the session
- Allow notification permission so recording status can stay visible.
- Review battery optimization settings if your phone is aggressive about stopping background apps.
- Keep Bluetooth enabled and avoid vendor power-saving modes during longer tests.
Use connected sessions, not idle sessions
MultiHR is most reliable when the app is actively connected to devices and running a real session.
If there are no connected devices, Android is more likely to treat the app as inactive work that can be limited.
What to do during longer recordings
- Start the recording only after every required device is connected.
- Keep the phone near the sensors and avoid toggling Bluetooth or battery saver in the middle of the session.
- If your device brand is known for killing background apps, keep MultiHR in the foreground for critical sessions whenever possible.
What to review if a session stops
- Whether notification permission was denied.
- Whether the app was excluded from battery optimization.
- Whether Bluetooth connectivity dropped for one or more devices before the recording stopped.
