How to change the time on the Xiaomi phone: from basic settings to reset

Correct display of time on a smartphone is not just a matter of convenience, but a critical function for the stable operation of the entire operating system. MIUI Mistakes of time stamps can lead to inability to connect to Wi-Fi, malfunctions in messengers, refusal of authorization in banking applications and problems with security certificates. POCO Often encounter a situation where the clocks are behind or running forward, especially after crossing borders or shifting SIM-map.

While most of the time the system can handle the synchronization itself, manual adjustment or forced resetting is often the only solution, and understanding how to change the time on a xiomi phone can help avoid many of the technical problems associated with network protocols and software conflicts.

Below, we’ll look at all possible scenarios, from standard time zone change to deep-tuning system settings through an engineering menu, and timing accuracy affects logging events, alarm clocks, and even the correct display of notifications from Google servers.

⚠️ Warning: Abruptly changing the date several years ahead or back may cause a “security certificate is not valid” error in all browsers and applications that require a security certificate. HTTPS linkage.

Automatic synchronization through the network

The easiest and most reliable way to get the exact time is to entrust it to automation. Android, in conjunction with the MIUI shell, uses NTP (Network Time Protocol) to retrieve data from atomic clocks via the Internet or cell tower. To activate this feature, go to the Settings menu → Additional settings → Date and time.

Here, the user will see the "Use Network Time" switch. When it's active, all other fields, such as time zone or time format, become unavailable for editing, as the system blocks manual input to avoid conflicts, a standard behavior for modern smartphones, ensuring uniformity of time stamps across all services.

If the time has not changed after this option is turned on, there may be a temporary failure in the data transmission from the operator, in which case the flight mode is turned on and off, which causes the modem to re-register in the network and request current parameters.

It is important to note that for automatic synchronization to work properly, the device must have access to the Internet at least when the screen is turned on. If the phone has been in aeronautical mode for a long time, time can be dissynchronized until the signal appears.

Manual date and time zone setting

Sometimes the automation fails, or the user is in a non-standard timeshift zone that is not automatically determined by the operator, in which case you need to know how to change the time on the xiomy phone manually, and to do this, you need to turn off the "Use Network Time" switch in the Date and Time menu.

After that, the fields for setting hours, minutes and seconds will be active. Special attention should be paid to choosing the time zone. Unlike older phones, where you needed to know the offset relative to GMT, modern Xiaomi interfaces allow you to choose a city or region from the list, which eliminates errors when switching to daylight saving time in different countries.

• 🌍 Region selection: Find the capital of your time zone (e.g. Moscow, Beijing, Berlin) on the list).
• 📅 Date format: You can choose the order of display (GYG-MM-DD or DD.MM.GYG), which affects the sorting of photos and files.
• 🕒 12/24 Time-format switch, important for those who are used to the American or European standard.

Manual installation is also necessary when testing applications or if you want to cheat the system to check the performance of functions in the past or future, but remember that manual change can disrupt the synchronization of contacts and mail.

If you travel frequently between time zones, turn on the option of "Automatic time zone change" in the same menu so that the phone itself rebuilt when changing. SIM-map.

Problems with desynchronization after the shift SIM-map

A common problem owners Xiaomi and Redmi — resetting time when installing a new SIM-The smartphone may incorrectly read the time zone information provided by the base station, which causes the clock to show the time of the previous region.

To solve this problem, you don't have to go into deep settings. Often, it's enough to just reboot a device from a new one already installed. SIM-When you boot, the system reinterviews the communication module and gets the correct data. LAC (Location Area Code, which is linked to a specific time zone.

If the reboot didn't help, check the settings APN Sometimes providers transmit incorrect time parameters through their access points, in which case resetting the mobile network settings to factory values in the Settings menu will help. → SIM-maps and mobile networks → Access points (APN) → Drop it.

⚠️ Warning: When changing the region of stay manually, do not forget to check whether the "Do Not Disturb" mode on the phone is activated on the schedule, since it is tied to the local time of the device.

Resetting time settings through the engineering menu

In difficult cases, when a software failure does not allow you to change the time by standard methods, you can use the hidden engineering menu, which is a powerful diagnostic tool, but requires caution. To get there, open the Phone application and type the combination # #3646633##.

In the EngineerMode interface that opens, go to the Connectivity or Telephony tab (location may vary depending on the MediaTek or Qualcomm processor), and you can find the NITZ (Network Identity and Time Zone) settings that are responsible for getting time from the network.

The path in the engineering menu (example):


Telephony -> NITZ Time -> Enable/Disable

Disconnection and re-enactment of reception NITZ-The modem can force the modem to request time from the base station, but this method is only suitable for advanced users, since changing other parameters in the engineering menu can lead to loss of communication or unstable operation of the radio module.

The Impact of Wrong Time on Applications

Many users underestimate the importance of accurate time until they find half of the applications stop working. Security protocols like SSL/TLS use timestamps to verify the validity of certificates. If the time on a device differs from the real one by more than a few minutes, browsers will give a connection error and banks' applications will refuse to run.

Also, data synchronization suffers. Google Photos, Gallery, and messengers use the file creation time to sort it out. If you take a photo while the phone is on the wrong date, that picture can fly off to the very end or beginning of albums, and it's extremely difficult to restore the chronology of events.

In addition, antivirus databases and security updates also depend on the relevance of system time. If the clock is a year behind, the phone may believe that the last check was just taken and miss critical threats.

What to do if time is constantly being reset

A situation where after a full battery drain or reboot, the time is reset to default (for example, January 1, 2020), indicates a hardware problem. Inside the smartphone, in addition to the main battery, there is a tiny backup battery or capacitor that stores time data and system settings in the off state.

If this cell fails or is completely discharged due to a long downtime of the phone, the system will “forget” the time every time it shuts down. In most modern Xiaomi, this feature is tied to the main battery, so deep discharge of the main battery also leads to a reset.

• 🔋 Deep discharge: If the phone has been empty for several months, let it charge when it is off at least 2-3 hour.
• 🛠 Hardware defect: If the problem recurs continuously even with a charged battery, a plume replacement or motherboard repair may be required.
• 🔄 Firmware failure: Sometimes a full reset to factory settings (Wipe Data) helps, but it will delete all user data.

⚠️ Note: Before performing a full reset (Wipe Data), be sure to back up all important data, as it will be impossible to restore them after that without a previously created copy.

In rare cases, the cause may be a conflicting application that has the rights to change system time. Check the list of installed programs and remove those that require strange permissions or were downloaded from unverified sources.
