Set time and date on Xiaomi Redmi 8: automatic synchronization and manual settings

Xiaomi Redmi 8 is a popular smartphone with MIUI functional firmware, but even experienced users sometimes have questions about basic settings. One of the most common is how to set the time, date or alarm, especially if the watch starts to “hurry up” or lag after the system update. In this article, we will discuss all the ways to adjust the time on Redmi 8, including hidden nuances that are not described in the official documentation.

Watch problems on Xiaomi can manifest themselves in different ways: from banal failure after replacement SIM-We'll look at not only standard methods (automatic network synchronization), but manual settings, as well as ways to diagnose problems. If your Redmi 8 is showing the wrong time, this guide will help you get everything back to normal without resetting to factory settings.

Why is Xiaomi Redmi 8 running out of time?

Before you go into settings, it is important to understand the reasons for the failure. On Redmi 8, the clock may not work properly due to:

• 📶 Network Disability – if mobile internet or Wi-Fi is disabled, automatic time synchronization (NITZ) doesn't work.
• 🔄 Errors after the update MIUI — Especially relevant for older MIUI 12, where there were timezone bugs.
• 🔋 Module malfunction RTC (Real-Time Clock – a hardware fault in which the clock is reset after the power is turned off.
• ⚙️ Manual time zone changes – if the user manually set the wrong region (for example, GMT+0 instead GMT+3 Moscow).

In practice, 90 percent of problems are solved software-enabled, such as turning on automatic sync or resetting time settings, but if the failure repeats after rebooting, it may indicate wear on the RTC battery (occurring on devices older than 3-4 years), which is responsible for saving time when power is turned off.

⚠️ If after replacing the battery with Redmi 8 clock resets every time you turn off – most likely, the wizard did not connect the contact RTC-The battery (it is soldered into the motherboard) in this case, only re-repair will help.

Method 1: Automatically adjusting time over the network

The simplest and most recommended method is synchronization via mobile network or Wi-Fi.

1. Open the settings (cog icon on the desktop).
2. Go to the section Additional settings → Date and time.
3. Activate the switches: 🔄 Date and time autodetermination – synchronization over the network. 🌍 Time zone autodetermination - pulls up the time zone by geolocation.

If you have already turned on, but the time is still incorrect, try manually selecting a time zone (e.g. Moscow, GMT+3) and turning on automatic synchronization again. Sometimes the failure occurs due to a conflict between the operator’s network and Google settings (if you use a GMS account).

After activating automatic synchronization, the time should be updated within 1-2 minutes. If this does not happen, check the network settings or try the method below.

Method 2: Manually set date and time

If automatic synchronization does not work (for example, if there is no network), you can set the time manually:

1. Go to Settings → Additional settings → Date and time.
2. Turn off the options Autodetermining Date and Time Zone and Autodetermining.
3. Click on the Set a date and Set a time to enter values manually.
4. For the time zone, choose the nearest city (for example, Kyiv or Minsk for GMT+3).

Manual setting is suitable for a temporary solution, but note that without synchronization over the network, the watch can gradually “go away” (especially if the smartphone is rebooted often). RTC-module.

💡

If after manual settings time is reset when restarting - try calibrating RTC-module through the engineering menu (see section "Additional methods").

Setting up the alarm clock on Xiaomi Redmi 8

The alarm clock settings are worth considering separately, as they are not system time-dependent, but often raise questions. Redmi 8 uses the standard MIUI Watch app:

1. Open the Clock app (a dial icon).
2. Go to the Alarm (Bell icon) tab.
3. Press + in the lower right corner to add a new alarm clock.
4. Set a time, select repetition days and a melody.
5. Activate the switch Enable (right of time).

⚠️ Warning: If the alarm doesn’t work, check if the notifications for the Watch app are turned off (Settings) → Annexes → The clock → Also make sure that the smartphone does not go into deep sleep mode (relevant for users of power saving features).

Additional methods: engineering menu and RTC calibration

If the Redmi 8 time is knocked down regularly (for example, after each shutdown), the problem may be in the red. RTC-The Real-Time Clock can be recalibrated through the engineering menu:

1. Open the phone app and enter the code: ##4636##
2. Select the section Information about the phone.
3. Scroll down to the RTC block and press RTC Calibration.
4. Confirm the action and restart the device.

This procedure resets the module’s internal clock and can help with minor failures, but if the problem is related to hardware wear (such as a dead RTC battery), calibration will give a temporary effect.

Solving time failure issues after MIUI update

Redmi 8 users often experience a time glitch after a MIUI update, especially when upgrading to version 12.5 and higher, due to a conflict between system services and Google's settings.

1. Open Settings → Accounts and Synchronization.
2. Delete your Google account (if it is linked).
3. Reboot your smartphone.
4. Add a Google account again and enable time synchronization.

Also help reset network settings:

1. Go to Settings. → SIM-maps and mobile networks → Resetting network settings.
2. Confirm the action and restart the device.

If the problem persists, try rolling back to the previous version of MIUI or resetting to factory settings (with data saved).

Comparison of time setting methods on Xiaomi Redmi 8

For most Redmi 8 users, it is enough to enable automatic synchronization. If that doesn't help, try manually adjusting or calibrating the RTC. In extreme cases (hardware malfunctions), repairs may be necessary.

If time is lost only when you turn off your smartphone – this is 100% a sign of a problem with the smartphone. RTC-In this case, the software methods won't help, you need repairs.
