## What is Battery Saver?

Know if your battery has what it takes to survive the day.

Hasta La Battery, Baby watches your device’s battery level and charging state, learns your normal drain pattern over time, and steps in when the current trend says your power reserve needs backup.
 
* Check your current battery level and charging state
* See calibration progress as the app learns your routine
* Get local notifications when the drain becomes serious
* Run a manual check whenever you want
* Keep your battery history and preferences on your device

Background checks are scheduled by iOS and may not run at exact times. The app does not track you, create an account, contact a server, or share your battery history.
