You have your own Xiaomi Redmi Note 12 or POCO X5 Pro, when the screen goes out, the logo appears MIUI, And it starts over without you, and it's a phenomenon that users call re-run, and it's found on Xiaomi smartphones from the budget Redmi to the flagship Xiaomi 14. But why is it? Is the renuna a sign of a breakdown or is it normal behavior of the system?
In this article, we will look at all possible causes of reran, from software failures to hardware problems, learn how to distinguish โsafeโ reboots from critical ones, and give step-by-step instructions for diagnosing and troubleshooting. Particular attention will be paid to models from 2023-2026, where the reran is often associated with HyperOS updates and new Qualcomm Snapdragon chips.
Spoiler: 80 percent of the time, the problem is solved without going to the service center, but there are exceptions, and we'll talk about them.
What is renun and how does it manifest itself in Xiaomi
The term โreranโ (or โrebootโ in the Xiaomi community) refers to an unexpected smartphone reboot that occurs for no apparent reason. Unlike โhangโ (when the screen freezes and does not respond to presses), when the reran, the device turns off and re-engineered, sometimes with a characteristic vibration.
What does it look like in practice?
- ๐ฑ The screen goes out, the logo appears. MIUI/HyperOS, Then there is a standard loading.
- ๐ Reboots can occur once a day or every 10 minutes โ depending on the cause.
- ๐ Sometimes the ram is accompanied by a battery discharge of 5-10% (especially on older models).
- ๐จ On some devices, a message appears before the reran: Android has stopped responding.
It's important to understand that not every reboot is a ram, for example, if you manually click Reboot on the power menu or install a software update, it's normal behavior, and Reran is only an uncontrolled process that you're not the one who initiated.
Top.-5 Reasons for Xiaomiโs Reran: From Innocuous to Critical
The causes of sudden reboots can be divided into two groups: software (software related) and hardware (hardware problems), and below is a ranking of the most common causes, from the simplest to the most complex.
Application failures
First, third-party applications conflict with the system, and most often, the rams provoke:
- ๐ฎ Games with high demands (Genshin Impact, Call of Duty Mobile).
- ๐ฑ Applications for overclocking the processor or cleaning memory.
- ๐ VPN-Clients and antiviruses (such as Kaspersky or Avast).
- ๐ค Root access programs (if you have access to them).
As a rule, the failure occurs when several โheavyโ applications are running simultaneously or when the system tries to close the โhungโ application.
2. Updates MIUI/HyperOS
More 30% rams on Xiaomi 2023โ2026 Years associated with the transition to HyperOS or unstable updates MIUI 14/15. The problem is particularly relevant for models:
- ๐ฑ Xiaomi 13/13 Pro (upgrade to HyperOS) 1.0).
- ๐ฑ Redmi Note 12 Pro+ (trouble MIUI 14.0.4).
- ๐ฑ POCO F5 (Conflicts with Google Services).
Often, the ram occurs immediately after the update is installed or after 1-2 days when the system tries to optimize the operation of background processes.
3. Processor overheating
Xiaomi smartphones on Snapdragon chips 8 Gen 2/3 or Dimensity 9000+ They're prone to overheating, which can cause an emergency reset:
- ๐ก๏ธ 60โ65ยฐC โ start trottling (productivity restriction).
- ๐ก๏ธ 70ยฐC+ โ high-risk.
Overheating is aggravated by:
- ๐ Fast charging (especially on Xiaomi 14 Ultra with a slicker-than-life version) 120W).
- ๐ฎ Long-term play sessions.
- โ๏ธ Use in the sun or in a stuffy room.
4.Battery problems
If your Xiaomi is older than 2-3 years, the cause of the ram may be a worn-out battery.
- ๐ Sudden jumps in charge level (e.g., from 30% to 1%).
- โก The device turns off at 10-15% charge.
- ๐ฅ The battery is swelling (check if the back cover is moving away).
On newer models, the ram may be associated with a malfunction of the power controller (for example, after a fall or moisture).
Hardware malfunctions
The most serious reasons for repair:
- ๐ ๏ธ The dump of memory chips (often after blows).
- ๐ Problems with the power connector or plumes.
- ๐งฒ Damage to the motherboard (for example, after water is ingested).
If the ram is accompanied by artifacts on the screen, no vibration, or broken buttons, it is almost always a hardware problem.

How to diagnose the cause of renamine: step-by-step instructions
Before you bring your phone to the service, try to determine the cause yourself. Here is a diagnostic algorithm that will help narrow the range of problems:
- Check the reboot logs Go to Settings โ The phone. โ Version. MIUI and press 5-7 times on the kernel version to activate Developer Mode. โ Additionally. โ For developers, look for Bug Report, and you can see which application or process caused the reran.
- Run Safe Mode Press and hold the power button, then press the power off before a request to switch to Safe Mode appears. If there are no rams in this mode, the third-party application is to blame.
- Check the temperature of the processor Install the application CPU Monitor AIDA64 And watch the temperature of the chipset if it's over 65.ยฐC at normal load - the problem is overheating.
- Type ##4636## into your phone number, select Battery Information and check the Battery Health setting, a value below 80% indicates wear and tear.
โ Check the logs of failures in the developer mode
โ Testing in Safe Mode
โ Measure the temperature of the processor
โ Check the battery's health
โ Make sure that the ren is not related to a specific application
-->
If after all the checks the cause remains unknown, try resetting to factory settings (don't forget to make a backup!).
๐ก
If the ram only happens when you connect to a charger, try using a different cable and power supply. Often the problem lies in a faulty accessory, not in the phone.
How to eliminate renamine: solutions for every cause
Depending on the diagnosis, the treatments will vary, and here's a table of solutions for the most common cases.
| Cause of reran | Elimination | Difficulty |
|---|---|---|
| Conflict of applications | Remove newly installed programs. Clear cache for all applications in Settings โ Apps: Turn off auto-start for suspicious apps. | โญโญ (easily) |
| Failure after the update MIUI/HyperOS | Reverse to the previous version of the software via Fastboot. Clear the update cache in Settings โ Memory. โ Clean up. Wait for the next patch (usually in 1-2 weeks). | โญโญโญ (middle-of-the-road) |
| Processor overheating | Remove the case and let the phone cool. Turn off background processes in Settings โ Battery. Reduce screen resolution and refresh rate. Replace the thermopaste (in service). | โญโญโญ (middle-of-the-road) |
| Worn-out battery | Replace the battery (cost: 1,500โ4,000) โฝ). Calibrate the battery (discharge to 0%, then charge to 100% without interruptions). | โญโญโญโญ (difficult) |
| Hardware malfunction | Contact the service center for the diagnosis of the motherboard or plumes. | โญโญโญโญโญ (difficult) |
If you are not sure of your abilities, do not try to disassemble the phone yourself - especially for models with adhesive housing (Xiaomi 13 Lite, Redmi Note 11 Pro).

Most of the rerans on new Xiaomi models (2023-2026) are related to the transition to HyperOS. If the problem appeared after the update, first try to roll back on the HyperOS. MIUI 14 or wait for a correctional patch.

Reran prevention: how to prevent sudden reboots
You can't completely eliminate the risk of renamine, but you can reduce it significantly.
- ๐ฑ Update your software regularly, but donโt install betas unless youโre bug-ready.
- ๐งน Clean the cache once every 1-2 weeks (Settings) โ Memory. โ Cleanup).

- ๐ After installing a major update (e.g., with a MIUI 13 on HyperOS).
- ๐ฑ When first switched on after resetting settings.
- ๐ง After manually shutting down via Fastboot or ADB.
Also, some Xiaomi models (such as Black Shark for gamers) can be rebooted when Performance Mode is activated.
โ ๏ธ Warning: If the reran occurs every 5-10 minutes or the phone does not turn on after the reboot (hangs on the logo), this is a sign of a serious malfunction!
Conclusion: What to do if nothing helps?
If you have tried all the tips from this article, but the reran continues, there are two options:
- Contact the official service center Xiaomi (especially if the phone is warranty). โฝ, repairs - from 1,500 โฝ.
- Sell/exchange a phone if the hardware problem and repair costs more than 50% of the price of the device. In the secondary market, Xiaomi smartphones with ram lose up to 30-40% of the cost.
