Changing the time zone on Xiaomi smartphones is a seemingly elementary procedure, but many users face unexpected difficulties. The device stubbornly returns the old settings after rebooting, automatic time updates work with errors, there is no desired city in the list. In this article, we will analyze all the current ways to change the time zone on any Xiaomi models, from budget Redmi to flagship Xiaomi 14, including the features of the MIUI and HyperOS firmware.
It's important to understand that a misconfigured time zone doesn't just affect the timing of the time, but it's dependent on synchronizing notifications, alarm clocks, correct call logs, and even some of the features of banking applications. We'll look at both standard methods through the settings menu and the hidden capabilities for power users -- including ADB commands and system file editing.
Why it is important to set the time zone correctly
At first glance, a wrong time zone is just a small inconvenience, but in practice, the consequences can be much more serious:
- 📅 Calendar disruptions: Meetings and reminders will shift by hours, with missed deadlines.
- ⏰ Alarm clocks: The device may be triggered 3 to 12 hours earlier or later than a predetermined time.
- 💳 Problems with banking applications: some services (for example, SberBank Online or Tinkoff) block transactions when the system time diverges from the server.
- 📱 Sync errors: Google Photos, Telegram messages and other data can be displayed with incorrect timestamps.
This is especially important for users who:
- 🌍 Travel frequently between time zones (e.g. Moscow) ↔ Yerevan or New York ↔ London).
- 💼 Work with international clients or remote teams.
- 🎮 Participate in online events (streams, tournaments, webinars) where time accuracy matters.
Method 1: Automatic time zone determination
The easiest way is to entrust the time setting to the system.
- Open the settings (cog icon on the desktop).
- Go to Additional Settings → Date and time (the HyperOS path may differ: System and device → Date and time).
- Activate switches: Autodetermining date and time (uses network data) Time zone autodetermination (geolocation)
The system will automatically pull data from the mobile operator or through Google Services (if installed), which is suitable for most users, but has limitations:
Not all operators provide correct time zone data
Roaming can be defined by the belt of the host country, not the home
On some firmware (for example, custom) the function is disabled by default
In an airplane or without a network, geolocation does not work.-->
| Situation | Decision |
|---|---|
| The phone shows the time of the past country after the return | Manually update network data in Settings → SIM-maps and mobile networks → [yours SIM] → Update the network |
| Automatic definition is turned off by itself. | Check permissions for the Settings app → Apps → Permissions |
| Time strays after reboot | Reset network settings: Settings → Reset settings → Reset network settings |
⚠️ Note: On HyperOS devices (e.g. Xiaomi 14 or Redmi Note 13 Pro)+) Automatic determination may conflict with Smart Assistant. If time is lost, turn off time optimization in Settings → Battery → Smart assistant.
Method 2: Manual time zone change
If the automatic mode doesn't work, you can manually select the time zone, which is more reliable, because it doesn't depend on the quality of the communication or the operator's settings.
Instructions for MIUI 12-14 and HyperOS:
- Go to Settings → Additional settings → Date and time.
- Turn off the switches Autodetermining Date and Time Zone Autodetermining.
- Select the time zone line.
- Enter the name of the city in the search box (for example, Moscow, Novosibirsk, London) or select a region from the list.
- Confirm the choice - time will be updated immediately.
Method 3: SIM-card swap (for two SIMs)
If your Xiaomi supports two of your SIM-The time zone can be tied to an active line, and it's convenient for traveling when one is in the same zone. SIM local and the second is a home operator.
How to set up:
- Go to Settings. → SIM-maps and mobile networks.
- Choose. SIM-The card to which you want to tie the time.
- Activate the option to use the time of this SIM-maps (the name may vary).
This method is useful if:
- 🌐 You move between countries frequently and want time to automatically adjust to your local operator.
- 📱 You two. SIM-cards with different rates (for example, one for calls, another for the Internet), and you want to tie the time to the "main" line.
⚠️ Note: On some models (e.g, POCO X5 Pro or Redmi K50) This function is not effective if one of the SIM-Check before using the card that both SIM active.
Solving the problems with time lost
If the time zone resets after a reboot or changes accidentally, try these methods:
1. Network resetting
Often helps in conflicts with the operator:
- Open Settings → Reset settings → Reset network settings.
- Confirm the action (password or fingerprint is not required).
- Restart your phone and check the time.
2. Cleaning the cache of the Settings application
Sometimes the system cache contains outdated data:
- Go to Settings → Applications → Application Management.
- Find the Settings app (cog icon).
- Tap Clear the cache (not data!).
3. Verify synchronization with Google
If you use a Google account, time can be synced through its services:
- Open Settings → Accounts and Sync → Google.
- Make sure that the date and time synchronization is enabled.
- If necessary, turn it off and turn it back on.
💡
If the problem persists, try temporarily disabling battery optimization for the Settings app. Go to Settings → Battery → Battery Optimization, find Settings in the list, and select No Limits.
4. Check the timezone file (for experienced)
Some firmware stores the time zone in a system file to verify it:
- Install a file manager with root access (such as Root Explorer or FX File Explorer).
- Go to /data/property/persist.sys.timezone.
- Check that the file contains the correct belt (e.g. Europe/Moscow).
⚠️ Note: Editing system files requires root rights and can cause a device to crash.Without experience, not recommended!
Features for different Xiaomi models
Depending on the model and firmware version, the process may differ, and the following are key nuances for popular devices:
| Model/Series | Features of setting the time | Typical problems |
|---|---|---|
| Xiaomi 13/14, Redmi Note 12/13 (HyperOS) | Menu moved to System and device → Date and time. Supports Smart Sync with weather widget. | Conflict with the function "Energy saving" - time can be lost when the battery is low. |
| POCO F5/X5 (MIUI 14) | Additional option Game mode can block automatic time updates. | In manual mode, the list of cities is not displayed in full - a search by name is required. |
| Redmi 10A/12C (budget models) | There is no time-bound function to SIM-Autodetermination works only over the mobile network (Wi-Fi is not supported). | Switching between 3G/4G can be a 1-2 hour time-consuming process. |
| Xiaomi Mi 11/12 (MIUI 12.5–13) | Supports synchronization with Mi Account – time can be updated when you log in to your account. | After upgrading to MIUI 14, there may be failures – you need to reset your date and time settings. |
For HyperOS devices (2026), Adaptive Time has been added to take into account your habits, for example, if you usually wake up at 7:00, the system can automatically adjust the alarm clock time when you change your belt to turn off this feature:
- Go to Settings → System and Device → Date and Time → Additional.
- Turn off Adaptive Time and Smart Adjustment.
Additional settings for travelers
If you often cross time zones, set up your phone for maximum convenience:
- Add the watch widget to the home screen: Long-press on the desktop → Widgets → Watch. Choose a style with multiple time zones.
- Set up belt change notifications: In Settings → Notifications → System notifications enable the Time Zone Change option.
Use the applications to synchronize:
- ClockSync – Forced to update time on atomic servers.
- Time Zone Converter – helps to quickly transfer time between belts.
