Battery optimization settings can block data transmission between your mobile phone and tado° and therefore adversely affect the accuracy of the geofencing features of tado°.

On Huawei phones with Android 7 (Nougat) and Android 8 (Oreo) apps by default are unprotected from the operating system auto-close function. To protect the tado° app from the auto-close function please follow these steps:

1. Open the Settings on your mobile phone
2. Enter the Apps section (placed under “Apps & Notifications” in Android 8)
3. Select the tado° app in the list
4. Tap on Battery
5. Switch off the Power-intensive prompt option
6. Android 7: switch off the Close after screen locked option
   Android 8: enter the Launch section, switch the Manage automatically slider to off, ensure that all manual sliders in the pop-up screen are activated and confirm by pressing OK

Additionally the tado° app has to be excluded from battery optimization. To disable battery optimization for the tado° app please follow these steps:

1. Open the Settings on your mobile phone
2. Enter the Apps section  (placed under “Apps & Notifications” in Android 8)
3. Press the gear symbol
4. Navigate to Special access
5. Go to Ignore battery optimization
6. Ensure that all apps are shown in the list
7. Select Allow in the pop-up screen for the tado° app and confirm by pressing OK.
