Possible scenarios are:
1, for non-original charger, this is due to the specification of the charger is not up to standard, replace an original charger can be.
2, if the original charger appears the above fault, please check whether the data cable is normal. The data cable looks normal on the outside, but it may have been broken inside. My data cable was broken only when I cut the outer plastic. Check method is to borrow someone else's data cable to see if it can be charged. 4, the display plug symbol is normally full to show 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 good, the battery is broken. Apple mobile phone charging precautions: 1, the new machine is recommended not to rush to charge, normal use of electricity to the screen prompts 10% need to charge. Then shut down, shut down and charge once. The new machine is best to use electricity for the first time, it is recommended not to use it up! The new lithium-ion polymer battery, unlike the old battery, has no memory effect. 2, plug the data cable first, and then plug the socket.
3, at least once a month must be used up, shut down, and then fully charged.
4, other times the power is less than 50% and then charged, plug in the computer charging.
5, this is the best battery protection, the other 3G network and dynamic screen display this option can not open, very battery consumption.
