The Battery Optimizer feature maintains the performance of the battery, both in terms of individual ride time as well as the overall lifespan of the product. When activated, the optimizer performs a voltage equalization of the battery's cells to optimize the hardware's performance.
The feature is available directly from the home screen of the app and contains all the information you need on how to get started. Note that the latest version of the app and a stable internet connection are required. Also note that the optimization will most likely take some time, so it’s a good idea to use a spare phone or tablet for this.
If you are having problems with discovering your battery via the Battery Optimizer feature, please follow this instruction.
