Parental control on Huawei.
EMUI and HarmonyOS are the most aggressive systems at killing background apps. Here are the settings so Quiles survives.
The problem
Huawei has one unique and brutal mechanism.
PowerGenie
EMUI's battery manager kills any foreground service 30 minutes after it moves to the background, unless the app is on the App-launch whitelist set to manual mode.
AppGallery rejects accessibility
Huawei's own store rejects parental-control apps built around accessibility services. Quiles is distributed through Google Play, not AppGallery.
No Google services
Models from 2019 onwards (Mate 30 and after) don't ship with Google Mobile Services. Without GMS, installing Google Play requires MicroG or similar, which is outside the scope of this guide.
Step-by-step setup
Two essential settings in EMUI / HarmonyOS.
App launch on manual
Settings → Battery → App launch → Quiles → Manage manually. Enable all three switches: auto-launch, secondary launch and run in background. Without all three, PowerGenie kills Quiles after 30 minutes.
No power restriction
Settings → Apps → Apps → Quiles → Power usage → Restricted: off. This second layer doubles the guarantee: even if the system decides to save energy, Quiles is excluded from the cull.
Confirm accessibility
Settings → Accessibility features → Installed services → Quiles → Enable. Accept the Huawei safety warning. Without accessibility, Quiles cannot lock the screen during breaks or school hours.
The automatic wizard
Quiles automates almost everything during onboarding.
When the child's phone is a Huawei, Quiles opens the OEM autostart wizard with direct deep-links to the App-launch and power-usage screens. It guides you switch by switch and verifies each one is on before moving to the next.
EMUI sometimes reverts permissions after a monthly security update. If Quiles detects that a setting has dropped, it shows a card on the parent's main screen the next time you open the app. Re-accepting takes under a minute.
HarmonyOS 4 and later reorganise menus: "App launch" can appear as "Launch management" inside Optimise. Quiles detects the exact HarmonyOS version and adjusts the path. If a deep-link screen fails, the wizard falls back to the full manual path so you are never stuck.
About phones without GMS
An honest note about post-2019 Huawei.
Huawei phones released from 2019 onwards (Mate 30, P40, Mate 40, Nova series) don't include Google services. Quiles is distributed on Google Play. Installing Quiles on one of these models requires MicroG or a similar layer that provides the bits of Google Play apps expect.
This is outside the scope of this guide and, frankly, outside the product we sell. If you want to use Quiles on a post-2019 Huawei, the simplest path is to buy a phone with GMS out of the box. The experience is much better than patching around it.
If your Huawei is older (P30, Mate 20, etc.) or you already have GMS installed and working, the two settings above are enough for Quiles to enforce schedules stably.
About Honor: the first Honor generations shipped with EMUI before the brand split off. If your child has an older Honor running EMUI, the guide is identical. Recent Honor phones (post-2021) run MagicOS, which resembles EMUI but with reorganised menus. The paths are equivalent; the OEM wizard detects them and shows the right variant.
One final thing: Huawei tablets share the same battery manager as the phones. If you give your child a MatePad as a school device, apply the same two settings. The same caveats about post-2019 GMS apply to the tablets too, a MatePad released after 2019 will most likely lack Google services out of the box.
