Have you ever wondered why your Xiaomi starts to slow down after a few months of use, even though the specifications remain the same? The reason often lies not in the hardware, but in the software processes that accumulate in RAM over time. Rebooting a smartphone is like a short sleep for its operating system: it clears the cache, closes the “hungry” applications and returns the device to its original performance. But how often should you do this to avoid harm?
Owners of Redmi Note 12, POCO X5 or flagship Mi 13 face conflicting advice: some recommend rebooting the phone daily, others – once a month, and still others claim that modern smartphones do not need it at all. In this article, we will understand what reboot mode is optimal for different Xiaomi models, how it affects the battery and performance, and also reveal the myths of “harmful” reboots.
Why Reboot Is Important for Xiaomi Smartphones
The MIUI operating system (even in the latest version of MIUI 14) is built on Android, and thus inherits its key feature: fragmentation of RAM. Every open application, background process or system service takes up a part of RAM, and over time this “residual” data accumulates, slowing down the device.
- 🧹 Clearing the app cache – remove temporary files that take up space and may conflict with new data.
- 🔄 Resetting the state of the OS kernel - minor errors in the work of the processor and graphics accelerator are corrected.
- 📱 System Services Updates – After Rebooting MIUI Restarts background services (e.g. Google Play Services) which eliminates lags.
- 🔋 Battery controller calibrations – reset errors in the calculation of the charge level (relevant for phones older than 2 years).
Not all reboots are equally useful, however: For example, a forced power button reboot (when the phone freezes) can damage the file system if the data is being recorded at that time, and too frequent reboots (for example, every day) reduce the life of the eMMC/UFS flash memory where the OS is stored.
Optimal reboot frequency for different scenarios
There is no universal answer to the question of how many times a week you need to reboot Xiaomi, because it depends on:
- 📱 Smartphone models (budget Redmi with 4 GB of RAM need to be rebooted more often than Mi flagships with 12 GB).
- 🎮 Loads (Game phones like Black Shark warm up more and require reboot to cool down).
- 🔄 Versions MIUI (into MIUI 14 optimized memory, but older versions — MIUI 12 and below - "flowing" more strongly).
We analyzed data from Mi Community forums and DXOMARK lab tests to make a table of recommendations:
| Type of use | Recommended frequency | Reason. |
|---|---|---|
| Office work (mail, messengers, calls) | 1 time 5-7 days | Low load on RAM, but background processes accumulate. |
| Active use (social networks, photos, videos) | 1 time 3-4 days | Multitasking quickly fragments memory. |
| Games (Genshin Impact, PUBG Mobile) | After each long session (or 1 time in 2 days) | Games take up to 70% of RAM and overheat the processor. |
| Smartphone as a “bell ringer” (minimum use) | 1 time 10-14 days | System processes almost do not load the device. |
A critical nuance for owners of Xiaomi with AMOLED-screens (e.g. Mi 11 Ultra or Redmi) K50 Pro: If you work long hours without rebooting, you may experience pixels burning up due to static interface elements (such as the notification panel).In this case, restart your phone at least once every 3 days to reset the display cycle.

How to reboot Xiaomi correctly: step-by-step instructions
It would seem that it could be easier than pressing the power button, but even in this process, there are nuances that can help avoid problems.
- Close all applications through the multitasking menu (swipe up from the bottom edge of the screen).
- If the phone is too hot, let it cool for 5-10 minutes (especially for the POCO F4 GT or Black Shark 5).
- Press and hold the power button (or Power + Volume up combination on some models).
- Select Reboot. Do not use Turn Off and then turn on, this may lead to a file system check on the next run.
For advanced users, there is an alternative way through ADB (if USB debugging is enabled):
adb shell rebootThis method is useful if the power button is not working but requires a connection to a PC.
What to do if Xiaomi doesn’t reboot?
⚠️ Warning: Never remove the battery for a forced reboot (relevant for older models like Redmi) 4X This can damage the power plume or contacts!
Myths about reboot: what is true and what is not
There are a lot of tips on how to reboot smartphones online, but most of them are either outdated or lacking technical justification.
- 🔄 «You have to reboot every day. — Lies. — Android Smartphones 12+ and MIUI 13/14 Optimized for long-term reboot-free operation. Daily reboots only wear out flash memory.
- 📉 «Reboot resets the battery charging cycle. — Half-truth. It resets the software meter (which may be wrong), but it doesn't affect the physical wear and tear of the battery.
- ⚡ «After the reboot, the phone works faster. — True, but temporarily. The effect lasts 1-2 days until the RAM is again filled with background processes.
- 🛠️ «Reset fixes all the lags" - Lies. If the brakes are related to damage to the firmware or hardware, the rebuke won't help.
One of the most enduring myths is that turning off your phone at night is good, and in fact, it's not only pointless for Xiaomi, it's also bad.
- 🔋 Night shutdown interrupts background optimization processes MIUI (For example, defragmentation of memory).
- ⏱️ In the morning, you will have to wait for the system to load, which eats up time.
- 📡 Nighttime app and security updates are disabled.
💡
If you fundamentally turn off your phone at night, use the “Air mode” (Settings) → SIM-maps and mobile networks → It'll shut down communications, but it'll keep the backgrounds. MIUI working-age.
The effect of rebooting on the battery: test data
Many users are afraid to reboot Xiaomi for fear that it will reduce battery life, and to dispel this myth, we analyzed data from Battery University’s tests and Xiaomi’s reports on battery durability.
- 📊 One reboot cycle (off) + on) consumes 0.1-0.3% of the battery life (provided that the charge is not lower than 20%).
- 🔥 Overheating when charging damages the battery 10 times more than rebooting. POCO X3 Pro could reduce battery life by 15-20% per year.
- 🔄 Regular reboots (1 every 3-5 days) prolong battery life, as they reset the errors of the power controller.
The table below shows a comparison of the impact of different actions on battery wear (data for Xiaomi batteries with a capacity of 4000-5000 mAh):
| Action. | Loss of capacity per year (%) | Equivalent in reboot cycles |
|---|---|---|
| Daily reboot | 1–2% | ~365 cycles |
| Charging games (1 hour/day) | 20–25% | ~7,000 cycles |
| Continuous operation without rebooting (30+ days) | 5–7% | ~2,000 cycles |
| Use of non-original RMS | 10–15% | ~3500 cycles |
Bottom Line: Rebooting once a week damages the battery less than one hour of gaming while charging. So don't be afraid to press Reboot!
Automatic Reboot: How to Set Up on Xiaomi
If you forget to manually restart your phone, MIUI offers a tool for automatic reboot on schedule, which is hidden in settings and not available on all models, but can be activated via:
- Open the Settings. → The phone.
- Press 5-7 times on the MIUI version to activate the developer mode.
- Return to the main settings menu and select Additional → For developers.
- Find Auto-reboot and set a time (e.g. 3:00 a.m.).
If this option is not available, you can use third-party applications like Automate or MacroDroid (ADB rights are required).
Trigger: Time (e.g. 03:00)
Action: Execute the command → reboot
Limit: Battery charge > 30%⚠️ Note: Automatic reboot settings on models with MIUI 12 or lower may conflict with Battery Optimization. If after setting up the phone starts to drain faster, turn off the automatic reset and restart manually.
What to do if Xiaomi is worse after the reboot
Sometimes users experience the opposite effect: after a reboot, the phone starts to lie down even more, and this can happen for several reasons:
- 🗑️ The system cache is damaged - after the reboot MIUI Trying to recover corrupted files, which takes up resources.
- 🔄 Update conflict – if the reboot occurred during the update installation MIUI, The system can get stuck on the old version with new libraries.
- 📱 Lack of memory – on phones with 3-4 GB of RAM (for example, Redmi) 9A) After the reboot, there may not be enough resources to run all services.
Here is the algorithm of actions if after the restart the phone began to work worse:
Check the space in memory (Settings → Storage)|
Disable unnecessary background apps (Settings → Apps → Auto Run)|
Clear the system cache (Settings → Storage → Clear the cache)|
Check the temperature of the processor (use it). CPU Monitor from Google Play)|
If nothing helps, reset your settings (Settings). → Resetting settings)-->
If the problem recurs after each reboot, it may indicate:
- 🛠️ Damage to section /system — need to be reflashed.
- 🔋 Battery Failure – If the phone turns off at 20–30% charge.
- 📱 Hardware wear – on phones older than 3 years can degrade flash memory.
💡
If Xiaomi doesn't turn on at all after the reboot (black screen, no vibration), don't try charging it - this could be a sign of a short circuit.
