One of the most frustrating things about using a mobile is do not receive notificationsEspecially if there is no exact model of why they happen or stop happening, it only happens sometimes or in certain applications. And that’s exactly what happens in some Huawei mobiles.
Some Android customization layers rely on somewhat aggressive battery-saving techniques, which “kill” processes faster than the standard Android method. Huawei mobiles include not one, but two systems in this regard, being Most restrictive PowerGenie of them, although they are virtually unknown.
What is PowerGenie
First things first, what exactly is PowerGenie? From the user’s point of view, it is a mysterious application present in most Huawei mobiles launched with EMUI 9 or higher. The app cannot be opened, has no icon, and has no options. In the latest versions of EMUI, it is officially called How arealthough in the past it was called Electrical engineering.
As explained in DontKillMyApp, PowerGenie is an energy management system that kill apps that are not on an inclusion list. The main problem with PowerGenie is that as a user you cannot exclude a PowerGenie app, but rather a list controlled by Huawei.
The two names of PowerGenie
PowerGenie should not be confused with the power consumption optimization options accessible from the mobile battery settings. Here in the section Start of application You can prevent Huawei from managing the power consumption of certain apps by switching to Manage manually.
In other words, a Huawei mobile has two filters to kill processes to save battery. The first is the optimization of the application startup, configurable by the user. The second is PowerGenie, in which the end user cannot make any changes.
Huawei’s power optimization itself is customizable
There is little public information about how PowerGenie works, as there is no official documentation on this, although the company has confirmed its existence from time to time, as well as the important detail that an app cannot be added to the inclusion list.
The APK application, which occupies only 77 kilobytes, includes several Google, Android and Huawei application lists to which, presumably, some of the restrictive energy conservation policies do not apply.
Presumably some of the applications excluded from PowerGenie
It’s great, but as a user how does that affect you? On the one hand, with a more restrictive application management policy, the mobile battery can last longer. However, it is possible that do not receive notifications from certain apps, especially ones that you haven’t used for a long time or are not very popular, like Facebook or Google apps.
For example, if you have installed an application to remember to water the plants and notifications do not appear even if you have configured it for manual management in the power options. If your plants die, it’s not your fault, it’s PowerGenie’s.
How to deactivate PowerGenie
That said, if you want to disable PowerGenie, you can, although it is not easy. You will need to use ADB commands and we do not recommend doing so unless you know what you are doing and are satisfied that PowerGenie is affecting the way you use your mobile.
First of all, it never hurts to make one PowerGenie APK Backup. You can do this with ML Manager or other similar apps. The process is as simple as finding PowerGenie in the system apps section and pressing Extract (or Share, to send to another app). You can really rehabilitate it again with another ADB command, but it never hurts to have a copy of it just in case.
So now is the time connect to mobile via ADB. Here we have told you about the process several times, which consists of three steps. Download ADB to the PC, connect the mobile to the PC with a USB cable, and run some commands on the command line to establish the connection. The mobile must have activated the usb debugging and development options.
To verify that the ADB connection between Android phone and PC is correct, you need to type ADB devices and receive an answer display « device » next to your device. If so, then you are ready for the next step.
If so, it’s time to run the command to uninstall PowerGenie. Run the command adb shell pm uninstall –user 0 com.huawei.powergenie, hit enter and if all went well you will receive the text within seconds Success.
It is done. If you search for PowerGenie (or Haware) on your mobile, it will no longer appear among the installed system apps. Now is the time you should check if your mobile loses fewer notifications than before, especially in apps that you’ve already manually configured in power options.
If you notice that your phone is worse than before or you prefer to leave PowerGenie as it was, bringing it back to life is as easy as making it disappear. Also using ADB, use the command adb shell cmd package install-existing com.huawei.powergenie. As if by magic, PowerGenie will rise from its ashes. Restart your phone to make sure it turns back on.
