Therefore the actual data may not reflect the most recent battery level, although we are trying to keep it as close to real-time as possible to ensure you are not viewing out of date data. The usual refresh interval for notifications and complication data is in the range of 5 to 60 minutes. ► SUPPORT The main objective of Battery Life is to give users an overview of their device's runtimes and battery charge level. If you are unsure about a battery replacement or just want to give us some feedback, feel free to send us an e-mail through the app’s contact form or tweet us (@BatteryLifeApp).
