Have you ever wondered why your Xiaomi smartphone runs out at night even if you're not using it? Or did you want your phone to automatically shut down at certain times -- like before bedtime, so you don't get distracted by notifications? The solution is there: it's a power timer, a hidden but extremely useful feature in MIUI firmware. Many users don't even know it exists, although it can significantly extend battery life and simplify everyday use of the device.
In this article, weβll take a closer look at what a power timer is, how it works on different Xiaomi models (from the budget Redmi to the flagship Xiaomi 14), and why it should be set up today. Youβll learn not only basic instructions, but also hidden chips that the manufacturer does not advertise β for example, how to use a timer to automatically restart the system or save charge in standby mode. And weβll also answer frequent questions: does the feature affect performance, can it be adjusted to regularly fire and what to do if the timer once stopped working.
What is a power timer and why is it needed
Power Timer is a built-in feature in MIUI that allows you to schedule your smartphone to automatically shut down or restart at a given time. Unlike a standard alarm clock that just makes a sound, the power timer physically shuts off the device's power, which is useful in several scenarios:
- π Battery savings: If you sleep and your phone is on charge all night, the extra hours of network connection reduce battery life%.
- π΄ Digital detox: Automatically turning off your phone before bedtime can help you avoid the temptation to flip through social media feeds or respond to messages at night.
- π Regular reboot: weekly rebut clears RAM and prevents system βhangsβ (relevant for models with 4-6 GB of RAM).
- πΆ Parental controls: You can schedule a childβs gadget to be turned off at a specific time to limit use.
Itβs important to understand that a power timer is not the same as a Sleep Mode or Digital Wellbeing, it doesnβt block notifications, it shuts down power completely, as if you had pressed the power button, and all background processes (including downloading updates or synchronizing data) stop.
What Xiaomi models have a power timer on
The power timer feature is available on all Xiaomi smartphones running MIUI 12 and later, including:
| Series of devices | Supported models (examples) | Notes |
|---|---|---|
| Xiaomi (flagships) | Xiaomi 14/13/12, Mi 11, Mi 10 | Full support, including advanced reboot settings |
| Redmi (middle segment) | Redmi Note 12/11/10, Redmi K60/K50 | There are basic features, but there may be no weekly timer option |
| POCO | POCO F5/X5, POCO M6 | Function is present, but the path to settings may be different |
| Black Shark | Black Shark 5/4 | Power timer works, but may conflict with game modes |

Hidden Power Timer Opportunities: 5 Chips You Didn't Know About
Most users use a power timer only to switch off the phone, but the feature has some non-obvious uses:
- π Set up a weekly reboot (like Sundays at 3:00) β this will clear the cache and prevent the system from βbraking.
- π΅ Lock your phone while you sleep Program shutdown at 23:00 and turn on at 7:00 β so you will not wake up from night notifications, and in the morning the phone will be ready to work.
- π If you put your phone on overnight charging, the timer will turn it off 1-2 hours after reaching 100%, preventing overcharging.
- π¨βπ©βπ§βπ¦ Parental control 2.0 On a childβs phone, set the switch off at 21:00 and turn on at 8:00 β so the child will not use the gadget at night, but in the morning will be able to call you.
- π If the phone started to glittle, schedule a reboot for the next 5 minutes - this often solves problems with the "hang" interface.
An important nuance: on some models (for example, Redmi Note 10 Pro) the power timer may conflict with the Always On Display function. If the screen does not go out after turning off, turn off AOD in the display settings.

The power timer does not cancel the alarm clocks set, and if you have an important signal scheduled (for example, in the morning), it will work even after the phone is automatically turned off.
Frequent problems and their solutions
Despite the simplicity of the function, users often face difficulties.-5 problems and ways of eliminating them:
β οΈ Note: If the power timer does not work POCO or Black Shark, check if Game Turbo is activated, blocking background processes, including scheduled tasks.
| Problem. | Possible cause | Decision |
|---|---|---|
| Timer doesn't work. | Conflict with battery optimization | Add the Settings app to power saving exclusions |
| The phone is switched on spontaneously | An alarm or notification has been triggered | Check alarm settings or turn off Auto-On option when notified |
| There is no "timer of power" item on the menu | Outdated version of MIUI or custom firmware | Update your software or use third-party apps (such as MacroDroid) |
| Timer's not working correctly. | Incorrect time on the device | Synchronize time through Settings β Additionally. β Date and time |
If none of these methods helped, try resetting the system settings:
- Go to Settings β About the phone β Reset settings.
- Select Reset all settings (without deleting data).
- After restarting, set the timer again.
Alternatives to the built-in power timer
If your Xiaomi model does not have a built-in timer or it is unstable, you can use third-party solutions:
- π€ MacroDroid App allows you to create automatic scripts, including turn off / reset by time. Supports conditional logic (for example, "turn off if charged") > 80%Β»).
- β° Automate is a more advanced automation tool, and you can set up a chain of action to turn off Wi-Fi. β wait 5 minutes β turn off the phoneΒ».
- π The app doesnβt turn off the phone, but limits charging to a certain level (e.g. 80%), which is useful for saving the battery.
Third-party applications have the advantage of flexibility, for example, MacroDroid can program:
IF (time = 23:00) AND (battery charge > 30%)
