Accu-Chek SmartGuide app
What happens if my phone battery dies?
If your phone battery dies, the Accu-Chek SmartGuide app does not receive glucose data from the sensor or provide notifications while your phone is powered off. Charge your phone as soon as possible, power it on, and open the Accu-Chek SmartGuide app. When your phone is powered on again and the app is running, it will download data from the sensor.
If your phone was powered off for more than 8 hours, the historical data may show some gaps when displayed on graphs.
