1, use the AC socket to charge, charge the power to 100% off, in the shutdown mode then charge to the green light.

2, clear the battery traces, start charging to 100% so that your battery has no memory after charging quickly, the first 80% of the battery is relatively fast, 80%~100% is relatively good at saturation.

3, please turn off those just said when charging, otherwise the charging will certainly be slow, the data cable and the charger should also match, try not to mix, the U port current of the computer is small.
The first step we need to make a judgment is that the charging interface of the mobile phone may have poor contact, and the possible reason is that it has not been cleaned for a long time, resulting in a lot of dust inside the interface. At this time, we must check the interface in time and clean up foreign bodies inside.
2. Check the data cable and try another one.
