Should you regularly reboot your Xiaomi smartphone on Android – and how to do it correctly?

Xiaomi smartphone owners often face conflicting advice: some argue that a once-weekly reboot is mandatory, others argue that modern Android devices do not need to be forced to shut down. Where is the truth? In fact, the frequency of the reboot depends on the Xiaomi model, the version of MIUI, the intensity of use and even the type of applications installed.

In this article, we will understand how often you need to restart Xiaomi to avoid “hangs” of the system, clean RAM and extend the battery life. Based on data from Qualcomm engineers (the manufacturer of processors for most Xiaomi smartphones) and analysis of user logs, we have compiled a unique table of optimal reboot modes for different use cases.+ or POCO F5) Especially sensitive to long-term work without restarting.

Why Xiaomi should be rebooted: 3 technical reasons

Even if your Xiaomi is running consistently, there are problems in the background that the reboot helps solve:

• 🔄 Cleaning up the cache of the Android kernel: After several days of continuous operation, the memory accumulates "junk" processes that the system cannot remove without restarting. MIUI 14+ Memory Extension (expansion of RAM due to ROM).
• 🔋 Battery controller calibration: Modern Xiaomi batteries (e.g., Xiaomi 13 Ultra) use Battery Health Charging algorithms that require periodic resets to correctly display the charge level.
• 🛠️ Resetting "stuck" services: Some system services (e.g. com.miui.analytics or android.process.media) can freeze, consuming up to 15% CPU Rebooting removes these processes.

Xiaomi engineers confirm that long-term work without rebooting (more than 7 days) increases the risk of lags in multitasking by 40%, while for flagship models (for example, Xiaomi 14 Pro), this figure is lower due to the optimized core Qualcomm Kryo.

💡

If your Xiaomi suddenly starts to run 10-15% overnight on standby, first aid: reboot. 60% of the time, this solves the problem without resetting.

Xiaomi’s official recommendations: what the manufacturer says

The documentation for Xiaomi smartphones (Battery and performance section) indicates that a reboot of 1 time every 3-5 days is considered optimal for most models.

• 📱 Version MIUI: Nana MIUI 12-13 Rebooting was required more often due to memory management bugs, while MIUI 14+ better optimized.
• 🔌 Type of use: Gamers and users of resource-intensive applications (such as Genshin Impact or Lightroom Mobile) should reboot more often.
• 🔄 Custom firmware: Devices with Xiaomi.EU or PixelExperience may require weekly reboot due to unstable cores.

Interesting fact: in the service centers Xiaomi in the diagnosis of "brakes" first check uptime (continuous operation time) through the command:

adb shell cat /proc/uptime

If the value exceeds 604,800 seconds (7 days), experts recommend restarting until further manipulations.

Table: Optimal reboot frequency for different Xiaomi models

Note: for models with MIUI HyperOS (e.g. Xiaomi 14), rebooting is not so much important for cleaning memory as for synchronizing the EROFS file system, which is used instead of the traditional ext4.

How to Reboot Xiaomi: 5 Steps to Safety

It's not enough to just press the power button. To make the most of the restart, follow this algorithm.

Close all applications through the multitasking menu

Turn off the charger (if the phone is charging)

Make sure that no files or updates are uploaded

Take a screenshot of important notes/chats (in case of a crash)

Wait 10 seconds after turning off before turning on-->

Pay special attention to the charging item: rebooting during charging can cause a failure of the battery controller on some models (for example, the Redmi Note 9 Pro with a Snapdragon 720G chip), this is due to the fact that the QC 4.0 processor does not always correctly handle power interruption during reboot.

For advanced users: If your Xiaomi supports fastboot, you can perform a “deep” reboot via the command:

fastboot reboot

This cleanses dalvik-cache and resets kernel states, which is useful when “laying down” the interface.

💡

Never take it out. SIM-card or memory card during reboot – this can damage the slot on models with a hybrid tray (for example, Redmi) 10C).

What happens if you never reboot Xiaomi: the real consequences

An experiment conducted by XDA Developers magazine in 2023 showed that Xiaomi smartphones that work without restarting for more than 30 days demonstrate:

• ⚡ Increased energy consumption in standby mode 22-28% Due to background processes that the system cannot complete.
• 🐢 Slowing down animations MIUI (For example, the transitions between screens take up to 0.5 seconds instead of the standard 0.2c).
• 📉 Performance drop in benchmark: at Geekbench 6 fall 10-15% after 2 week-long.
• 🔴 Failures in the operation of sensors: the gyroscope and accelerometer begin to give inaccurate data (noticeably in games and in the game). AR-annexes).

Critical case: POCO X3 Pro after 45 days without restarting, a file system failure was recorded, in which the phone stopped recognizing the internal drive, the reason is an overflow of f2fs log (the file system used by Xiaomi for the /data partition).

💡

If your Xiaomi has started spontaneously restarting once a day, it's not always a failure. MIUI 14+ has an Auto-Optimization feature that can initialize a system cleanup reboot. Check Settings → Special features → Auto-Optimization.

When Xiaomi’s reboot could hurt: 3 dangerous scenarios

Despite the benefits, there are situations where a reboot can exacerbate the problems:

⚠️ Note: If your Xiaomi is in the process of updating MIUI (The Mi logo and progress lane are on the screen, and forced shutdowns will cause the device to "brick" (inoperability). EDL-service-centre.

Other risky moments:

• 🔄 During backup to Mi Cloud: Interrupting may result in data loss or archive damage.
• 📱 When recording video in an active way 4K/8K: On some models (e.g. Xiaomi) 13 Pro) this causes a codec error H.265, The following videos are recorded without sound.
• 🔋 At charge levels below 5%: A sudden power outage can damage the battery controller, especially on older models with 4300mAh batteries and below.

If you urgently need to reboot your phone in one of these scenarios, use a soft reset via a button combination:

1. Press the Power button + Volume up for 10 seconds.
2. Wait for the vibration and release the buttons.
3. The phone will perform a warm reboot (reboot without completely shutting down the power), which is safer for the system.

Alternatives to reboot: how to “refresh” Xiaomi without turning off

If you don’t want to completely restart your phone, but feel like it’s starting to slow down, try these methods:

• 🧹 Cleaning the cache with Recovery: Turn off the phone. Squeeze the power. + Increase volume to enter Recovery Mode. select Wipe & Reset → Wipe Cache – This method deletes temporary files without losing data.
• 🔄 Relaunching MIUI Launcher: Execute the command in ADB: adb shell am force-stop com.miui.home This will update the interface without a full reboot.
• 🔋 Activate Airplane Mode for 30 Seconds: Disables all communication modules, which sometimes helps with network or network problems GPS.
