Check whether the battery is damaged or has reached its service life. If the battery is damaged prematurely due to damage or improper use, you can try to change a battery to see if it can be started. If the problem is solved, the battery needs to be replaced.
The most easily damaged mobile phone fault is the cottage mobile phone that has been used for a long time with poor quality, which leads to problems inside the mobile phone and cannot be turned on. At this time, you can search the specific situation online, seek the help of netizens, or find after-sales solutions to carry out maintenance during the warranty period.
Man-made damage caused by water ingress or brushing is your own fault. If water enters, blow it with a hair dryer and open it for baking.

5.Dowell's mobile phone can't be turned on. What happened?
There are two situations when the mobile phone can't be opened:
First, the mobile phone has power but can't be turned on for the following reasons:
1, the boot line is not normal. Look: use an external power supply to power the mobile phone, and use an electric meter to check whether the indicator light has changed. If there is no change, it is likely that the boot cable is broken or the boot key is in poor contact.
2. The battery power supply circuit is abnormal: use the external interface to supply power to the mobile phone, and turn it on to see if it returns to normal. If it is normal, it is determined that the mobile phone power supply circuit is abnormal.
3. Abnormal mobile phone power IC: Test the peripheral circuit of the power IC against the circuit schematic diagram to see if the test value is normal.
4. The system clock and reset of the mobile phone are abnormal: you can use the dual main oscilloscopes to detect the CPU power supply of the mobile phone to see if the waveform in the reset is correct.

3. The plug symbol is usually displayed when it is full. Now it's full or low, but it can show that there is no problem with the tail plug of the mobile phone. You should try the charger first. If it still doesn't work, the battery is broken.
4. Again, check whether the original charger can work normally. You can connect the charger to another mobile phone with USB port to see if it works properly.
5. If the above two devices still can't be charged after inspection, please try to plug them into the USB port of the computer to see if the computer can recognize the mobile phone. If you can, see if it is charging. If it is recognized, it is estimated that it needs maintenance. If it cannot be identified and recharged, it must be repaired. If it can be identified and charged, please replace the data cable and charger with better quality.
6. See if the voltage is too low, or go directly to the maintenance station.
