How to set up a timer on Xiaomi: all the ways for smartphones and smart gadgets

The timer on Xiaomi devices is a versatile tool that can be useful in everyday life, sports, cooking or for monitoring work hours. Depending on the model (smartphone, Mi Band smartwatch, Mi Smart Speaker speaker or even robot vacuum cleaner), the settings may differ, but the principles remain similar. In this article, we will analyze all possible scenarios, from the standard countdown on the phone to automatically turning off music through the voice assistant XiaoAI.

Xiaomi’s ecosystem features deep integration between devices, such as a timer running on a Redmi Note 12 smartphone that can sync with the Mi Band 8 and vibrate on the wrist, and the Mi Smart Speaker series’ smart speakers can configure voice control of the timer via the command “Xiao Ai, set a timer for 10 minutes,” and we’ll look not only at basic features, but also at hidden features that aren’t mentioned in the official instructions.

1.Timer on Xiaomi smartphones: standard features

On all Xiaomi smartphones (from the budget Redmi to the flagship Xiaomi 14), the timer is built into the Watch app.

1. Go to the app menu and find the Watch icon (usually in blue or black with the dial).
2. In the bottom panel, select the Timer tab (an hourglass icon).
3. Turn the dial or click on the numbers to set the time.

By default, MIUI has presets: 5 minutes, 10 minutes, 30 minutes and 1 hour, but you can set any value up to 23 hours 59 minutes. Once you start, the timer will appear in the notification panel, and after time, the sound will go off (you can change the tune in the settings).

If you need multiple timers at once, click on the + icon in the upper right corner, which is useful, for example, when cooking multiple meals with different cooking times. Note that on older versions of MIUI (below 12), multiple timers may have been running simultaneously, and this problem has been fixed in new firmware.

⚠️ Note: If the timer doesn’t work, check if the Watch app has been added to the list of optimized Settings. → Battery → Optimize the battery, otherwise the system may suspend its operation in the background.

Voice Timer via XiaoAI: How to Control Voice

On devices that support XiaoAI voice assistant (smartphones, Mi Smart Speaker speakers, some Mi TV models), the timer can be started without manual input.

• 🗣️ «Xiao Ai, set the timer for 15 minutes»
• 🗣️ «Run the timer for 2 hours»
• 🗣️ «Remind me in 45 minutes" (this will create a reminder, not a timer, but functionally similar)

The voice timer is convenient when your hands are busy (such as cooking or training). On Xiaomi smart speakers, when the timer is triggered, the voice alert sounds, and on a smartphone, the standard signal. To cancel the timer with a voice, say, “Xiao Ai, cancel the timer.”

If the voice assistant does not respond:

1. Make sure that XiaoAI is enabled in Settings → Additional → Voice Assistant.
2. Check your internet connection (Xiaomi cloud is required to process voice commands).
3. Update the XiaoAI app to Google Play or the Mi App Store.

💡

If the voice assistant doesn’t recognize commands correctly, try speaking more clearly or switching to English (in some regions, Russian recognition is worse).

3.Timer on smart watches Mi Band and Watch

On the Mi Band 7/8 fitness bracelets and Xiaomi Watch smartwatch, the timer is customized via the device menu or the accompanying Mi Fitness (Zepp Life for new models) app. Instructions for Mi Band 8:

4.Switch off screen and device timer
