The Battery Optimizer feature maintains the performance of the battery, both in terms of individual riding 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 is required. Also note that the optimization may take a long time, and as such, we suggest you use a spare phone or tablet that you can leave unoccupied, if possible.
