Xiaomi and Redmi smartphones are famous for their MIUI feature shell, which provides users with extensive customization capabilities. However, as with any complex system, basic settings sometimes require manual intervention or adjustment, especially when displaying time and date, since these parameters affect not only the appearance of the lock screen, but also the operation of many applications, including banking clients, instant messengers and security services.
Incorrect timing can cause you to be unable to log in to Google or Xiaomi accounts, and can lead to data synchronization errors. In this article, we will take a look at all aspects of timing setup in detail, from automatic synchronization over the network to manual settings for regions where it is needed, learn how to change display formats, add clocks in other cities, and understand why settings are lost after rebooting.
Basic time settings in MIUI
To start working with time parameters, you need to get into the corresponding system menu. The standard path in modern versions of the shell is as follows: Settings → Additional settings → Date and time. In some firmware modifications, the section may be called simply “Date and time” and be located at the root of the settings menu or in the subsection “System applications”.
In the window that opens, the user sees a "Use Network Time" switch. If the slider is active (blue or green), the smartphone automatically receives accurate data from the cellular operator or via an Internet Wi-Fi connection. This is the most reliable way to avoid errors, since the device itself determines the time zone based on geolocation.
💡
If you travel frequently between time zones, leave the automatic determination on – the phone will switch to local time when connecting to a new network.
If the automation is not working properly or you need to manually set the parameters, you should turn off the "Use Network Time" slider, and then the manual input fields will be active, so you can change the current date, set the exact time to the right second, and choose a 12-hour or 24-hour display format.
Solving the problem of time reset after switching off
One common problem with Redmi and Poco budget models is to reset the time to a standard (often 00:00 or 1970) after a full battery drain or prolonged downtime, which is because the motherboard lacks a separate battery to store system time, or it has exhausted its life.
If your phone forgets time every time, you'll either have to put up with manual setup every time you turn on, or you'll have to use third-party solutions. Some users install alarm apps with their own interface that force you to sync the time when you start up before you even fully boot up.
⚠️ Note: If time is reset even when the battery is charged after rebooting, this may indicate a software failure in the module. RTC (Real Time Clock or damage to system files after a failed update.
It’s also worth checking if you have a Super-Saving mode in your power saving settings that can aggressively disable background synchronization processes. Try to remove system time services from your optimized application list, although MIUI often restricts access to this functionality.
Time zone setting and display format
Choosing the right time zone is critical for those who use their smartphones to work with international partners or make frequent calls to other regions, and there is a separate item on the Date and Time Zone menu, where you can not only select your region from the list, but also activate the Automatic Time Zone Change feature.
For the convenience of users who follow the cryptocurrency market or trade on exchanges, the MIUI shell features a “Double Clock” feature, which allows you to display the lock screen and the second city time in widgets, and you can activate this option by turning on the “Show Second City Time” switch in the bottom menu of the date settings.
Time formatting is also flexible. You can choose to display the date in the order of DD/MM/GYYYY or MM/DD/GYYYYYYY, which is especially important for users who moved from CIS countries to the United States or vice versa.
Synchronization through NTP and Internet services
Mobile operators don’t always provide perfect timing, sometimes it can take minutes to desynchronize. For maximum accuracy, modern Xiaomi smartphones use NTP (Network Time Protocol) protocol. To make sure your phone uses the most accurate source, you can check Google’s sync settings.
Go to Settings → Accounts and Sync → Google. Make sure sync is enabled. Often, it is the Google account that is the priority source of time for the Android system, interrupting the operator’s data. If time is still lying, try to delete and add a Google account.
For advanced users with Root rights, there are opportunities for forced change NTP-However, for most users of standard firmware, it is easy to switch the time source in the date settings from "Cellular Operator Network" to "Use Network Time" (which implies the Internet).
| Parameter | Automatically. | Manually. | Impact on the system |
|---|---|---|---|
| precision | High (up to milliseconds) | Depends on the user. | Critical for SSL-certificate |
| Time zone | Determined by GPS/network | Getting off the list | Affects alarm clocks and calendar |
| Transition to daylight saving time | Automatically. | Manual editing required | Maybe we can move the schedule. |
| Risk of error | Minimum | High-pitched | Blocking banking applications |
Additional functions: alarm clocks and timers
System time is the foundation of the Clock app. If the basic settings are down, the alarm clocks may fail at the right time or be delayed. In MIUI, the watch app has its own settings that can override the system settings if the Smart Alarm function is enabled.
This feature analyzes your schedule and can ignore your alarm clock on weekends if the algorithm decides you don't need to get up, and you can check these settings by opening the Watch app, clicking on three dots in the corner and selecting Settings.
The secret to alarm clock accuracy
And countdown timers are also worth mentioning, because they use system time to count intervals, and if you set a timer for 10 minutes, and at that point you manually changed the time an hour ago, the timer can be unpredictable, either counting down longer or resetting.
Specifics of settings for different Xiaomi models
The time setting interface may vary slightly depending on the Android version and the MIUI shell. On older models such as the Redmi Note 4 or Mi 5, the menu can be simpler, without dividing into additional sub-items. At the same time, the flagships of the Mi 13 or Xiaomi 14 series with the HyperOS shell offer deeper integration with services.
Owners of Chinese versions of smartphones (CN Version), which are installed on global firmware, sometimes face a problem when the time zone "China" is not removed from the list of priority. This is treated by resetting the region in the menu Additional settings → Region.
⚠️ Note: When changing the region of the phone, some system applications may restart, and the data in them (for example, notes or voice recorder) may become unavailable until reauthorization or synchronization.
Separately, it is worth saying about the Xiaomi Pad tablets. The logic of setting the time there is similar to the phone, but due to the rare use of the device. SIM-The cards in tablets are more dependent on Wi-Fi for synchronization. Make sure that the tablet is connected to the network at least periodically.
☑️ Checklist of time check
The impact of time on application performance and security
Many users don't realize how critical the right time is for digital security: The encryption protocols (SSL/TLS) used by browsers and banking applications check the validity of certificates based on the current time. If your phone is in 2015, no modern website will just open - you will see a connection error.
Two-factor authentication (2FA) in applications like Google Authenticator is also time-bound, codes are generated based on a time stamp, and a few minutes difference between the server and the device will cause the codes to consistently produce an error, even if you type it correctly.
💡
The right system time is not just convenience, but a prerequisite for the operation of a modern secure Internet and financial instruments on a smartphone.
In addition, the logs of events in the system, the history of calls and the chronology of photos in the gallery are based on time stamps. If you reset time in the past, new images can be "lost" in the archive among old photos, and it will be extremely difficult to find them without using a smart search by date.
