How to sync your Xiaomi Redmi 9 watch with your phone: all ways + error solving

Why it’s important to sync time on Xiaomi Redmi 9 and how it works

Precise time on a smartphone is not just a convenience, but the basis for many functions to work correctly, from alarm clocks and reminders to sync with cloud services and smart devices. On Xiaomi Redmi 9, time can be lost due to time zone change, resetting or network connection problems. But the main problem is when the phone clock does not match other gadgets (for example, with Mi Band or laptop), which leads to chaos in the schedule and notifications.

In this article, we will analyze all the current ways to synchronize time on Redmi 9: from automatic settings to the following: NTP-We will focus on synchronization with other Xiaomi devices (for example, with the Mi Watch or Redmi Note), as well as solving typical errors when time runs away or resets after a reboot.

If you find that after updating MIUI clock shows the wrong time or the difference with real time is a few minutes - do not rush to bring the phone to the service. 90% of the time the problem is solved software, and we will show you how to do it in 5-10 minutes.

Method 1: Automatic Network Synchronization (NTP)

The most reliable and recommended method is to use Network Time (NTP). Xiaomi Redmi 9 automatically pulls up accurate data from Google or Xiaomi servers, but sometimes this feature is disabled after a reset or update.

1. Open Settings → Additional → Date and time.
2. Activate the switches: ⏰ Autodetermining Date and Time (using network data). 🌍 Time zone autodetermination (important for travel).

If the options are already on, but the time is wrong, turn them off, restart the phone, and then turn them on again.

After activation, the phone will contact you. NTP-server (usually time.google.com or ntp.aliyun.com) and update the data.Please note: the function requires a stable connection to the mobile network or Wi-Fi. VPN, synchronization may be delayed.

💡

If you still get lost after you turn on NTP, try manually selecting a different time zone (for example, "Moscow +03:00" instead of "Auto"), then go back to automatic determination. This resets the time cache.

Method 2: Sync with your Mi Account

If you’re using the Xiaomi ecosystem (such as Mi Band, Mi Home or Mi Watch), synchronizing time through Mi Account will ensure a single time across all devices, a technique that’s especially useful if you have multiple devices of the brand:

1. Make sure your phone has Mi Account authorized (check Settings → Accounts → Mi Account).
2. Open an app associated with your device (like Mi Fit for a fitness bracelet or Mi Home for a smart home).
3. In the device settings, find the Time Sync or Date Settings section and activate the "Sync with Phone" option.

After that, all the connected gadgets will take time with Redmi 9. Importantly, if the phone itself time is wrong, then it will be lost on other devices. So first set the time on the smartphone (see Method 1), and then sync the rest of the devices.

Method 3: Manually adjusting time (if the automatic does not work)

If Redmi 9 is unable to connect to the NTP-Servers (e.g., carrier locks or Internet issues) will have to adjust the time manually, a method that can also be useful if you're in an area without network coverage.

1. Go to Settings → Additional → Date and time.
2. Turn off the options "Date and Time Auto Determination" and "Time Zone Autodetermination."
3. Click on the Set a date, Set a time and Select a time zone to enter data manually.

When manually adjusting, consider:

• ⏳ Time can run away for a few seconds a day due to inaccuracy of the phone’s hardware clock.
• 🌐 When crossing the boundaries of the time zone will have to update the settings yourself.
• 🔄 After connecting to the Internet, it is recommended to return to automatic synchronization.

Method 4: Sync via Bluetooth with other devices

If you want the Xiaomi Redmi 9 to show the same time as another smartphone, tablet or smartwatch, you can use Bluetooth sync.This method does not work with all devices, but is supported by most Xiaomi gadgets and some models of other brands (for example, Samsung or Apple).

Instructions:

1. Turn on Bluetooth on both devices and pair them (in the Settings menu → Connections → Bluetooth).
2. On the source device (from which time will be transferred), open the time settings and turn on the option "Allow Bluetooth synchronization" (the name may vary).
3. On Redmi 9, in the same time settings, find the Sync with other devices section and select the conjugated gadget.

Limitations of the method:

• 📱 It works only with an active Bluetooth connection (up to 10 meters distance).
• ⚠️ Not all devices support Bluetooth time transfer (e.g. older Mi Band models).
• ⏱️ The synchronization delay can reach 1-2 minutes.

Make sure Bluetooth is on both devices | Update the firmware on both gadgets |Check the battery (less than 15% sync may not work) |Disable the power saving mode

Solving the problem: why the time on Redmi 9 is out of sync

If after all the manipulations, the time on the phone is still incorrect or gets lost after a restart, the reasons may be as follows:

Special attention should be paid to situations where time is lost after turning off the phone, which may indicate a malfunction of the RTC (real time) battery, which keeps the clock running when the power is turned off, in which case only replacing the battery or motherboard will help.

💡

If time is lost after each reboot, try calibrating the RTC battery: completely drain the phone, then charge to 100% without interruption. In 30% of cases, this solves the problem.

Another common mistake is the time difference between the two SIM-So, if you use two cards, then the phone can hang between time zones. SIM-maps (Settings) → SIM-Maps and mobile networks) disable automatic timing for the second SIM.

Additional methods: third-party applications and ADB-team

If standard methods do not help, you can use third-party tools or ADB-commands for forced synchronization.

Method 1: Applications for time synchronization

Google Play has utilities that allow you to manually select NTP-server or forced to update the time:

• ⏱️ ClockSync supports more than 20 NTP-servers, there is a function of autosynchronization.
• 🌍 TimeZone Fix – fixes time zone issues after updates.
• 🔧 Network Time Protocol – for advanced users (allows you to configure your server).

Method 2: ADB-commands

If you are familiar with ADB, you can manually request to update the time:

adb shell settings put global auto_time 1


adb shell settings put global auto_time_zone 1




adb shell am broadcast -a android.intent.action.TIME_SET




adb shell am broadcast -a android.intent.action.TIMEZONE_CHANGED

These teams:

1. Include automatic determination of time and time zone.
2. Forced to send a signal to the system to update the data.

💡

Before using ADB, make sure that the phone is debugging over USB (Settings → About Phone → MIUI version – press 7 times, then go back to Additional → For Developers).
