When charging, the red light flashes to indicate that the power is switched on, and the machine cannot be turned on to indicate that it is not charged, the reasons and solutions are as follows:
1, for the non-original charger, it is easy to charge not into the power, because the charger specifications are not up to standard, replace a qualified charger can be.
2. Please check whether the data cable is normal. The data cable looks normal on the outside, but it may have been broken inside. Check method is to borrow someone else's data cable to see if it can be charged
3, the display plug symbol is normally full to display, now full or insufficient power, but you can show that the phone tail plug is no problem, you first change a charger to try, if it is still not the battery is broken.
4, again, check whether the original charger can work properly. You can connect the charger to another mobile phone with a USB port to see if it works properly.
5, if the above two have been checked and still can not charge, please try to insert the USB port of the computer to see whether the computer can identify the phone, can identify if it is charging, if it is identified but not charged, it is estimated that it needs to be repaired. If it cannot be identified and charged, it must be repaired. If you can identify and charge, then please replace the better quality data cable and charger.
6, see if the voltage is too low, not just go to the maintenance station.
