While BatterySync is open on each device, battery level changes are shared in real time.

When the app is in the background, updates occur only when the operating system allows them, so background updates are not always real time.

The timing of background updates is determined by the power management settings of iOS or Android. BatterySync cannot set a fixed update interval.

Yes. BatterySync can share data over a mobile data connection or any other internet connection. Information recorded while offline is updated after the connection is restored.

Force-quitting BatterySync may stop or destabilize background updates. On iOS in particular, updates will not resume until you open the app again. We recommend leaving the app running in the background.

Each device and operating system has different rules for reading battery information and limiting background activity. BatterySync displays the values provided by each operating system.

This is a limitation of the battery information that iOS provides to apps. BatterySync cannot change it to 1% increments.

Premium removes the device limit and lets you view up to 90 days of battery history. It also includes CSV export and Smart Alerts.
