📝 About this app
Battery Grapher graphs your historical battery levels and learns your habits to make smart predictions on what your future battery levels will be. Developed specifically with energy consumption in mind, Battery Grapher has almost no impact on battery life.
SMART PREDICTIONS
Battery Grapher uses historical battery levels to intelligently predict what your battery level will be throughout the rest of the day, allowing you to plan when to next charge your device. The longer you have Battery Grapher installed, the more accurate future battery level predictions will be.
LOW ENERGY CONSUMPTION
Battery Grapher is made for people who want to extend the battery life, meaning that low energy usage is a priority. The app runs a background task only once an hour, and doesn't require a network connection, which keeps energy consumption extremely low.
CUSTOMIZABLE NOTIFICATIONS
Battery Grapher allows you to set notifications that fit your needs. You can get the app to notify you when you battery drops below a preset percentage, or if you only have a certain number of hours left before your battery runs out. (currently only available on watchOS)
ALL COMPLICATIONS & WIDGET SIZES SUPPORTED
Battery Grapher supports all complications & widget sizes. Complications can show hours before needing to charge, or battery %. Both complications and widgets are customizable from within the app.
