ShareBattery is a free Android app developed by Trashfeed that provides advice on your Android device's battery life. Unlike other battery advisor apps, ShareBattery always operates offline and publishes information about your smartphone battery timing. The app allows you to check the battery information of different users of the same model, providing accurate and real battery information that is not listed in the catalog.

One of the best features of ShareBattery is that it helps you find the cause that is affecting your device's battery life by storing information about wifi, GPS, screen brightness, and more. Additionally, the app shares the OS version, model name, battery information (level, temperature, charge status), and country of the users who use the app. The app also provides the option to share additional information such as free memory, GPS, 3G, wifi, Bluetooth status, brightness, running apps, and running services, which is optional and turned off by default.

Overall, ShareBattery is an excellent app for those who are looking for an offline battery advisor app that provides accurate and real battery information.
