Batteries integrates battery levels across iPhone, iPad, MacBook and Watch. Experience Widgets: About to leave for work, university classes, or school and need to bring your MacBook with you? Know whether you should bring any chargers or cables just by looking at your iPhone's lock screen, which can elegantly display your MacBook's battery level so that you do not even have to take it out of your bag. Three home screen widgets were designed to integrate seamlessly with Apple's design language: single device, multiple devices or a device's history. Choose whichever fits best in your home screen. Lock screen widgets and Watch widgets were not left aside and offer the most convenient way to access the battery level of your devices. Charts: Batteries works with an entry-based design, which means that whenever possible the application will make an entry about your device's battery and send it to iCloud servers. Entries are used by Batteries to form useful charts that display the main battery level history and low power mode and charging analytics. Active synchronization: Background activity allows Batteries to maintain your devices in sync so that you rarely get outdated battery information. It is important to note that although Batteries uses multiple techniques to actively synchronize your devices, background network activity may be limited by the system. Batteries supports iPhone, iPad, MacBook and Watch. Other accessories are not supported by the application. Additional Information: - On iOS and watchOS, battery readings are provided in 5% steps, so displayed values may differ slightly from the exact charge level. - Your data stays private in your personal iCloud storage . - Requires iCloud and the same Apple ID on all devices.
