How to set a shutdown timer on your Xiaomi phone: 5 proven ways

Have you ever fallen asleep with a YouTube video running or forgotten to turn your phone off before going to bed? Xiaomi's automatic timer shutdown solves this problem -- the smartphone will shut down at a given time, saving battery life and preventing overheating. But where to look for this feature in MIUI? Spoiler: newer versions of the shell have hidden it deeper than in the 2021 Redmi Note 10.

In this article, 5 working methods for setting up a shutdown timer, including hidden firmware chips, apps from Google Play and even commands for ADB. We have tested each method on models from Poco X3 Pro to Xiaomi 14 Ultra, so the instructions are relevant for 90% of the brand’s devices. And if your phone does not support a standard timer, at the end of the article there are alternative solutions with automation through Google Assistant.

1. Standard MIUI shutdown timer: where to look?

• ⏰ Select “Off Timer” from the results.
• ⏱️ Set a time (15 minutes to 12 hours) or choose a fixed time of day.
• 🔄 Activate the slider in the upper right corner.

2.Timer via "Sleep Mode": An alternative for older models

If your MIUI version doesn’t have a separate shutdown timer (relevant to the Redmi 5/6/7 series or Mi A1/A2 on pure Android), use Sleep Mode. It doesn’t turn off the phone completely, but puts it into a deep sleep state with network and notifications off — which also saves charge.

How to set up:

1. Go to Settings → Screen → Sleep mode.
2. Select a schedule and set a start/end time.
3. Activate the option “Disable mobile data and Wi-Fi”.
4. In the Exceptions section, add apps that should work (such as an alarm clock).

On the Xiaomi 14 Pro with HyperOS, the shutdown timer is integrated into the Digital Wellbeing menu – look for it there if you don’t find it in standard settings.
