Reran on Xiaomi: why the smartphone itself reboots and how to fix it

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 โ€œsafeโ€ 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 โ€œreranโ€ (or โ€œrebootโ€ in the Xiaomi community) refers to an unexpected smartphone reboot that occurs for no apparent reason. Unlike โ€œhangโ€ (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?

  • ๐Ÿ“ฑ The screen goes out, the logo appears. MIUI/HyperOS, Then there is a standard loading.
  • ๐Ÿ”„ Reboots can occur once a day or every 10 minutes โ€“ depending on the cause.
  • ๐Ÿ”‹ Sometimes the ram is accompanied by a battery discharge of 5-10% (especially on older models).
  • ๐Ÿšจ 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.

๐Ÿ“Š How often does your Xiaomi reboot on its own?
Never.
Once in a few days
Every day.
Several times a day

Top.-5 Reasons for Xiaomiโ€™s 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:

  • ๐ŸŽฎ Games with high demands (Genshin Impact, Call of Duty Mobile).
  • ๐Ÿ“ฑ Applications for overclocking the processor or cleaning memory.
  • ๐Ÿ”’ VPN-Clients and antiviruses (such as Kaspersky or Avast).
  • ๐Ÿค– Root access programs (if you have access to them).

As a rule, the failure occurs when several โ€œheavyโ€ applications are running simultaneously or when the system tries to close the โ€œhungโ€ application.

2. Updates MIUI/HyperOS

More 30% rams on Xiaomi 2023โ€“2026 Years associated with the transition to HyperOS or unstable updates MIUI 14/15. The problem is particularly relevant for models:

  • ๐Ÿ“ฑ Xiaomi 13/13 Pro (upgrade to HyperOS) 1.0).
  • ๐Ÿ“ฑ Redmi Note 12 Pro+ (trouble MIUI 14.0.4).
  • ๐Ÿ“ฑ 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:

  • ๐ŸŒก๏ธ 60โ€“65ยฐC โ€“ start trottling (productivity restriction).
  • ๐ŸŒก๏ธ 70ยฐC+ โ€” high-risk.

Overheating is aggravated by:

  • ๐Ÿ”‹ Fast charging (especially on Xiaomi 14 Ultra with a slicker-than-life version) 120W).
  • ๐ŸŽฎ 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.

  • ๐Ÿ”‹ Sudden jumps in charge level (e.g., from 30% to 1%).
  • โšก The device turns off at 10-15% charge.
  • ๐Ÿ”ฅ 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:

  • ๐Ÿ› ๏ธ The dump of memory chips (often after blows).
  • ๐Ÿ”Œ Problems with the power connector or plumes.
  • ๐Ÿงฒ 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 distinguish software from hardware?
Software ram is usually: - Occurs in certain situations (when starting the game, after updating). - May disappear after resetting or flashing. - Not accompanied by physical damage (cracks, bloated battery). Hardware ram: - Occurs chaoticly, without reference to the user's actions. - Often accompanied by other symptoms (overheating, lack of charging). - Does not disappear after reset or reflashing.

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:

  1. 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.
  2. 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.
  3. 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.
  4. Type ##4636## into your phone number, select Battery Information and check the Battery Health setting, a value below 80% indicates wear and tear.

โœ… Check the logs of failures in the developer mode

โœ… Testing in Safe Mode

โœ… Measure the temperature of the processor

โœ… Check the battery's health

โœ… 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!).

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.

For owners of Xiaomi on HyperOS additional tip: disable unnecessary system services in Settings โ†’ Annexes โ†’ Application management โ†’ Systemic: Mi Video or Mi Browser, for example, often work in the background and can cause conflict.

๐Ÿ’ก

If you play heavy games often, install the Game Turbo app (available in GetApps) and activate cooling mode, which will reduce the load on the processor and reduce the risk of overheating.

When is renuna normal?

Yes, there are times when a reboot is not a failure, and here are the times when a reran is an expected behavior:

  • ๐Ÿ”„ After installing a major update (e.g., with a MIUI 13 on HyperOS).
  • ๐Ÿ“ฑ When first switched on after resetting settings.
  • ๐Ÿ”ง 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.

โš ๏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:

  1. Contact the official service center Xiaomi (especially if the phone is warranty). โ‚ฝ, repairs - from 1,500 โ‚ฝ.
  2. 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.

Before the service visit:

  • Backup all data (photos, contacts, messages).
  • Write down the serial number (on the box or in Settings) โ†’ The phone).
  • Check whether the warranty is maintained after repair (in informal services - usually not).
