That's because you play for a long time and the battery is automatically protected.

Hi 3, if you can't enter, please try to connect to the computer to recover.

Specific method: 4. If it still can't be recovered, please go to your nearest maintenance point for testing.

Today's smartphones will not be able to charge if they use too much electricity, so remove the battery, charge it with a charger for 5 minutes, and then install the battery to charge it for a longer time. This is how our mobile phone stores deal with this situation.

Reason: The phone is losing power badly, and the phone battery has entered a dormant state.

Solution: After charging for a period of time, try to turn on the device again.

Precautions for mobile phone charging.

1.The first charge does not have to be charged for 12 hours, it only needs to be fully charged.

2.It can actually be charged at any power level, and it has little effect on the battery.

3.It is best to have a complete release and charging process once a week. That is, from red to full, that is, it is best to achieve a battery that is almost exhausted once a week, and then fully charged.

4.The phone has the function of overshoot protection, but it is still recommended to unplug the phone when it is fully charged, and it is not recommended to charge it for a long time.

5.When charging to 100%, unplugging the charger is the best time, charging at 100% and charging for another hour, the battery power when unplugging the charger is not as good as when it is just 100% full.

The red light of Xiaomi Mi 2S charging keeps flashing, and it cannot be charged normally, so it is recommended that users bring their mobile phones, invoices, and warranty cards to the local brand customer service for testing.

After the phone is detected, the customer service will inform the user of the cause of the failure.

The warranty period of the mobile phone is 1 year, if the mobile phone is under warranty and is a natural failure, the after-sales service is responsible for the warranty.

If it is out of warranty or caused by a man-made fault, then you can only pay for repairs.

Hello. This may be that the battery has entered sleep, it is recommended not to run out of power and automatically shut down, please remove the battery for about 5 minutes. After putting it in, use a data cable to connect the computer and mobile phone for 30 minutes, and try to turn it on again.

If it still doesn't work, go to after-sales and solve it!

You will automatically shut down the phone when you run out of power, if you want to turn it on, you will exactly follow what I said, you first deduct the battery, and then charge the mobile phone without a battery, and directly install the battery after more than ten seconds, and try to turn it on after more than ten seconds, or it doesn't work, you are deducting the battery, repeat, but the mobile phone must be connected to the charger to charge consistently.

Here's why; 1.The phone is out of battery and automatically shuts down when it is used.

2.If the battery is too low, it will automatically shut down and the battery will go to sleep.

Resolution; 1.Remove the battery, and after five minutes, connect the charger to charge for more than half an hour before it can be turned on.

2.Connect the charger to charge. The phone LED may not light up at first, but after a few minutes, the red light of the LED starts flashing faster and faster, and it can be turned on when the red light is no longer flashing and is always on.

Plug in the charger, the indicator red light flashes for a while, and it does not flash for a while, indicating that the phone is fully charged.

There are several reasons why your phone has power but won't turn on:

1. The boot line is abnormal: use an external power supply to supply power to the mobile phone, use the electric meter to detect whether the indication has changed, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the peripheral circuit of the power supply IC according to the circuit schematic diagram to see whether the test value is normal.

4. The system clock and reset of the mobile phone are abnormal: you can use the dual total oscilloscope to detect the CPU power supply of the mobile phone to check whether the waveform in the reset is correct.

5. Problems with logic circuits: that is, faults in the circuit version of mobile phones, which can generally be solved by repair welding.

6. Software conflict: The installed software does not match the system of the mobile phone, which may also cause the mobile phone to fail to boot, you can connect the mobile phone to the computer to delete the program.

The same goes for my millet. It was broken once before and sent for repair that it was the motherboard burned, and it cost 300; This time it's the same situation.,After checking a lot of stickers, I found that the light kept flashing because the connection cable interface was not plugged in and not flushed into the power.,Or the battery was not installed.。 You unplug the data cable and plug it in a few more times, deduct the battery a few times and try again, I hope it will help you.

It is said that Xiaomi's after-sales service is very poor, I am now using Xiaomi mobile phones, some places to repair mobile phones, often deceive people, obviously very small problems, he told you that it is very big, mind that there are people you know, it is best to go to a few more to ask.

Are you stupid? That's when the phone runs out of power, and it'll be fine in a while.

Go to your local Xiaomi home, or go to an after-sales maintenance point for repairs.

Remove the battery and put it back on to see if it helps.

If it burns, it will be uncontrollable!
