Most of new smartphones use battery save algorithms that might close your HeiaHeia GPS-tracking
This algorithm is specially strong in Huawei-devices. If you use GPS-tracking when doing sports, this algorithm may cause your Huawei- phone to shut down in the middle of the GPS-tracking. With the following instructions, you can make changes to this in settings.
Open your Huawei smartphone's battery settings (Settings --> Battery). Access the "App launch" settings on your Huawei-device.
Here you see a list with all the apps that are installed on your device. HeiaHeia should be set as "Manage automatically" as well as other apps you do not want Huawei to close.
