Huawei - Interrupted Trainings

Modified on Thu, 21 Sep, 2023 at 12:15 PM

On some devices you may need to edit some settings to avoid trainings getting interrupted. Se below for a guide on how to allow the app to keep running in the background during your whole training

App Launch on some EMUI 8, 9 and 10 devices (Huawei P20, Huawei P20 Lite, Huawei Mate 10…)

Phone settings > Battery > App launch and then set your app to “Manage manually” and make sure everything is turned on.

1. *Phone settings > Battery > App launch*. This feature may or may not be available for all devices or labeled differently.

Also for reliable background processes you may need to uninstall PowerGenie as described below.

EMUI 9+ devices

Huawei is extremely inventive in breaking apps on their devices. In addition to all the non-standard power management measures described below, they introduced a new task killer app build right into EMUI 9 on Android Pie.

It is called PowerGenie and it kills all apps that are not on its whitelist. You cannot add custom apps on their pre-defined whitelist. This means there is no other way to fix proper app functionality on Huawei than uninstalling PowerGenie.

Unfortunately this is a system app and can only be fully uninstalled using ADB (Android Debug Bridge) Source: XDA.

You need to:

install ADB on your computer
Connect your phone with a data cable
Enable Developer options
Enable USB debugging within Developer options on your phone
Run the following commands on your computer:

adb shell pm uninstall --user 0 com.huawei.powergenie

We did not yet have this confirmed but it is possible you can alternatively just disable PowerGenie in Phone settings > Apps. This setting would need to be re-applied every time you reboot your device.

Please still follow the steps below - Huawei phones usually have multiple powersaving mechanisms.

Also, you may not have PowerGenie on your phone, but your apps may still get killed by another mechanism.

EMUI 6+ devices (and some EMUI 5 devices)

Phone settings > Advanced Settings > Battery manager > Power plan set to Performance
Phone Settings > Advanced Settings > Battery Manager > Protected apps – set your app as Protected
Phone Settings > Apps > Your app > Battery > Power-intensive prompt [uncheck] and Keep running after screen off [check]
Phone settings > Apps > Advanced (At the bottom) > Ignore optimizations > Press Allowed > All apps > Find your app on the list and set to Allow

Huawei P9 Plus

Phone settings > Apps > Settings > Special access > Ignore battery optimisation > select allow for your app.

Huawei Honor 9 Lite, Huawei Mate 9 Pro

Phone settings > Battery > Launch and then set your app to “Manage manually” and make sure everything is turned on. On EMUI 4 there is no way out, sorry, but you can ask developers of your apps to implement the workaround described in Developer section
