Xiaomi tablets are popular devices that combine performance and availability, but even they are not immune to sudden shutdowns. If your Mi Pad, Redmi Pad or POCO Pad turns off for no apparent reason, it's not always cause for panic. In 80% of cases, you can solve the problem yourself without resorting to a service center.
Spontaneous shutdowns can occur on both new and old models, but the mechanisms of failure often vary. e.g. tablets on MediaTek processors (e.g. Redmi Pad) SE) They are more likely to suffer from overheating, and devices with AMOLED-The Mi Pad 5 Pro, from problems with display drivers, will explore all possible causes, from the banal to the technically complex, and give clear instructions on how to fix them.
Important: If the tablet only turns off when connected to charging, the problem is most likely related to the power controller or cable. This is a separate case, which we will discuss in the corresponding section.
1. discharged or worn-out battery
The most obvious reason is low battery power, but even if the indicator is 20-30%, the tablet can turn off because:
- ๐ Uncalibrated charge sensor โ the device โthinksโ the battery is discharged, although it is not.
- ๐ Battery wear - after 500-800 Charging cycles, the capacity falls on 30-50%.
- โก Voltage spikes โ if charging is unstable, the system forcibly shuts off power.
How to check the status of the battery:
- Install the AccuBattery app (available for Xiaomi on Google Play).
- Charge the tablet to 100% and discharge to 0% without connecting the charging.
- Look at the discharge graph: if the voltage drop is sharp (from 3.8V to 3.2V in 10 minutes), the battery needs to be replaced.
โ ๏ธ Note: If the tablet is turned off when 40-60% If the battery is not charged and no longer switched on without a connection to the network, this is a sign of critical wear and tear of the battery!
Less than 10% |10-30% |30-50% |More than 50% |I don't know-->
2. overheating of the processor or other components
Xiaomi often uses powerful processors (such as the Snapdragon 870 in the Mi Pad 5), which can overheat when under intense load. Normal operating temperature - up to 45-50 ยฐ C. If the sensors fix 60 ยฐ C and above, the system forcibly shuts down the device to avoid damage.
Causes of overheating:
- ๐ฎ Long-term video game or rendering (especially in Genshin Impact, Call of Duty Mobile).
- โ๏ธ Direct sunlight or use on the street +30ยฐC.
- ๐ Clogging of ventilation holes with dust (relevant for Redmi Pad Pro with active cooling).
- ๐ ๏ธ Faulty thermal paste (on older devices or after falls).
How to diagnose:
- Install CPU Monitor or AIDA64 to monitor temperature.
- If the temperature exceeds 55 ยฐ C in the idle - this is an anomaly.
- Try running 3DMark or Geekbench: If the tablet shuts down after 5-10 minutes of testing, the problem is cooling.
๐ก
If the tablet overheats, remove the case and put it on a cooling stand (for example, Xiaomi Game Cooling Fan). 10-15ยฐC.
| Model tablet | Max. Processor temperature | Shutdown temperature |
|---|---|---|
| Mi Pad 5 / 5 Pro | 50-55ยฐC | 65ยฐC |
| Redmi Pad / Pad SE | 45-50ยฐC | 60ยฐC |
| POCO Pad | 48-52ยฐC | 62ยฐC |
| Mi Pad 4 | 40-45ยฐC | 55ยฐC |
3. Failure of firmware or software
Software errors are the second most common cause of blackouts, especially after:
- ๐ Updates MIUI (for example, transition MIUI 13 on MIUI 14).
- ๐ฑ Custom firmware installations (such as LineageOS or Pixel Experience).
- ๐งน Cleaning the cache through Settings โ Warehouse.
- ๐ Interrupt updates (if the tablet is turned off during installation) OTA).
Signs of software failure:
- The tablet is turned off on the MI logo or when downloaded.
- Before the shutdown, a message appears: โAndroid system has stopped.โ
- The device freezes before turning off (the screen flickers, does not respond to touch).
Decisions:
- Reset the settings to factory through Settings โ About Phone โ Reset settings.
- If the tablet is not turning on, go to Recovery mode: 1. Turn off the device. 2. Press <power button> + <volume button> for 10 seconds. 3. Select "Wipe data/factory reset".
- If the reset does not help, reflash the device through the Mi Flash Tool (instructions in the section about the firmware).

4.Problems with charging or power controller
If the tablet is turned off only when connected to charging, one of the components is to blame:
- ๐ Faulty cable/adapter โ cheap charging can give voltage surges.
- ๐ Damaged connector USB-C โ contact oxidation or mechanical damage.
- ๐ Failure of the power controller (e.g, BQ25890 Redmi Pad).
- โก Short circuit in the food chain (often after falls or moisture hits).
Diagnosis:
- Try a different cable and adapter (preferably the original Xiaomi on 33W or 67W).
- Check the connector for debris or damage (light with a flashlight).
- If the tablet is turned on only without charging - the problem is in the controller (repair is required).
โ ๏ธ Attention: If when connecting charging, the tablet heats up in the connector area USB-C And it turns off right away, which is a short circuit. Don't try to charge the device, call the service!
5. Hardware malfunctions: from display to motherboard
If the software methods didn't work, the problem could be the hardware.
| Component | Signs of malfunction | Possible solution |
|---|---|---|
| Screen (AMOLED/LCD) | Flickering before shutdown, artifacts, "broken pixels" | Replacement of a plume or matrix |
| RAM (Ram) memory (RAM) | Departures when launching applications, errors "Memory leak" | Chip soldering or board replacement |
| South Bridge (PMIC) | The tablet does not turn on without charging, discharges quickly | Chip repair or replacement |
| Antenna module (Wi-Fi/4G) | Disconnections when connecting to the network | Module replacement or modem firmware |
The most vulnerable models:
- ๐ฑ Mi Pad 4 โ Display plume problems (turns off when you press the screen).
- ๐ฑ Redmi Pad (2021) โ a defect in eMMC memory (departures when writing files).
- ๐ฑ POCO Pad - overheating of the module 5G (It is turned off during long-term Internet surfing).
โ ๏ธ Warning: If the tablet is turned off by physical action (for example, when you press the corner of the case), this is a sign of detachment of contacts on the motherboard. Self-repair is not possible - you need soldering in the service.
6.How to reflash Xiaomi tablet if it doesn't turn on
If the tablet is turned off during the booting phase or cyclically rebooted, flashing through Fastboot can help.This method is suitable for all Xiaomi models, but requires a computer and a computer. USB-cable.
Step-by-step:
Download Mi Flash Tool from the official website|Download the firmware for your model (for example, tissot_global_images...)|Install Qualcomm or MediaTek drivers|Disable the antivirus (it can block the process)-->
- Turn the tablet into Fastboot mode: 1. Turn off the device. 2. Press <power button> + <volume down button> for 10 seconds. 3. Connect to the PC - should be defined as "Fastboot device".
- Launch the Mi Flash Tool, select the downloaded firmware (file with the extension.tgz).
- Press Refresh โ Flash. It takes 5-10 minutes.
- Once completed, the tablet will restart. The first turn on can take up to 15 minutes.
โ ๏ธ Attention: Fastboot firmware erases all data! If there were important files on the tablet, try extracting them through the tablet first TWRP (if established).
1. Cable (requires original USB-C with data support).
2. USB port on PC (try USB 2.0 instead of 3.0).
3. Drivers (install Xiaomi Driver Installer).-->
7. When to contact the service center
Not all problems can be solved by yourself. Contact the service if:
- ๐ฅ The tablet swelled (seen over the bloated body or raised screen).
- ๐ง There was a ingress of liquid (even if everything is dry on the outside).
- ๐ After the fall, the power/volume buttons stopped working.
- ๐ Tablet does not turn on at all (no reaction to charging, buttons, connection to PC).
Cost of repair in official Xiaomi services (2026):
| Type of repair | Cost (โฝ) | Date(s) |
|---|---|---|
| Battery replacement | 3 000 โ 5 000 | 1-2 |
| Repair of the USB-C connector | 2 500 โ 4 000 | 1 |
| South bridge soldering | 6 000 โ 10 000 | 3-5 |
| Replacement of display | 8 000 โ 15 000 | 2-3 |
โ ๏ธ Warning: In informal services, repairs may be cheaper, but there is a risk of installing non-original parts (e.g. batteries without a temperature controller) that will result in repeated shutdowns!
