Reasons and solutions for failing to charge:
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. Although not all chargers are suitable for the iPhone, the iPhone charger is compatible with all USB phones.
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
I also encountered the same charge not into the problem, the battery hibernation, ha ha, go to the millet home repair, give me activated to 15% of the electricity let me go home to continue to charge, I for the sake of insurance in the Mi home charge to 20% specially shut down home, so that you can always start charging it. When I got home and the power was out, I couldn't understand why the shutdown status had changed from 20% electricity to 0%. Then the most difficult thing for me to think about is the battery hibernation setting of millet, think about the explanation of maintenance is ridiculous. Because of the battery protection, so there is no power in the case of millet mobile phone battery is a small current charging, and then a charge on the boot, boot power consumption is large, the battery is used up again, so the automatic shutdown, and then the small current starts, and then the cycle is never charged. In the after-sales repair, he actually took my battery in and charged it to 10% by the machine and then came out, which is called battery activation. Oh, such battery protection logic is also drunk. And tried a lot of methods to shut down charging simply can not do, a charge on the boot. Other places see people who have this problem and a bunch of people say that she is black, and there is this problem, so also come out to say my bad experience.
