Parental control on Xiaomi.
MIUI and HyperOS are aggressive with background apps. Here are the exact settings so Quiles does not get killed.
The problem
Xiaomi kills apps three different ways.
Autostart blocked
MIUI disables autostart for newly installed apps. Without Autostart, Quiles does not launch after a reboot and does not survive when memory is cleaned out.
Aggressive PowerKeeper
Xiaomi's battery manager kills foreground services after a few hours unless the app is whitelisted. That includes the service that enforces screen-time limits.
Second Space
Xiaomi lets users create a parallel profile where parental control does not exist. If your child finds it, they can sidestep Quiles without touching anything protected.
Step-by-step setup
Three settings in MIUI / HyperOS.
Enable Autostart
Settings → Apps → Permissions → Autostart. Find Quiles in the list and flip the switch on. This lets the app come back after a reboot or after the user clears every recent app.
Remove battery restrictions
Settings → Battery → Quiles → No restrictions. Also avoid extreme power-saving mode. Without this, PowerKeeper kills the service every few hours and the child gets the screen back without filters.
Lock down Second Space
Settings → Spaces → Second Space. If you don't use it, leave it off. If it is on for your model, set a password and don't share it. Quiles only governs the space it is installed in.
The automatic wizard
Quiles walks you through these screens during onboarding.
You don't have to remember each path. During setup, Quiles detects that the phone is a Xiaomi and opens the OEM autostart wizard: direct deep-links to Autostart, to PowerKeeper's whitelist and to the unrestricted-battery setting. Each step shows a visual check once complete.
If you add a second child later, the wizard only runs again if it sees that a setting has been reverted (MIUI does this occasionally after a major update). You don't have to navigate buried menus or hunt for screenshots in forums.
One caveat worth knowing: after a HyperOS update, MIUI sometimes resets autostart permissions. If you notice that rules aren't applying one day, open Quiles, let the checker review state and re-accept Autostart. Takes under a minute.
The wizard also installs a small daemon that runs every six hours and verifies the three settings are still in place. If a permission has been reverted, the daemon raises a card on the parent app immediately. No need to wait for a child to complain that an app they shouldn't be using suddenly works again.
Why it matters
Xiaomi dominates the market where Quiles is needed most.
In Spain, Xiaomi is the number-one Android brand in Tier-2 markets: mid-size cities, sub-300-euro phones, the teenager's first device. A parental-control launcher that doesn't work well on MIUI is useless for most real families.
Quiles invests specific time on MIUI and HyperOS because the alternative is to accept that half of buyers will have problems. The OEM autostart wizard keeps up with each major HyperOS release so the paths don't go stale.
If your child has a Redmi Note, a Poco or any Xiaomi-family handset from the last five years, the guide is the same. Older models (pre-MIUI 12) use slightly different paths, but the wizard recognises them and shows the correct route based on the installed version.
One last note: if you bought a Xiaomi imported from Asia, MIUI Global may behave differently from MIUI EU. Quiles works on both variants, but some setting translations change. If you can't find "Autostart", search for "Autostart" or "Automatic start" in the Settings search box.
