ZTE Yuanhang 4 can t be charged when it is turned on

Charger issues.

First, you should take a look at the power adapter you're using. As we all know, although the voltage of the mobile phone charging head is 5V, there is a big difference in the current size. At present, the standard charging current of most mobile phones on the market is more than 1A, and the standard charging current of tablets is more than 2A

If you plug your iPhone to the old 500mA charging head, it's not surprising that the charging is slow. Especially in this case, if you have to charge your phone at the same time, you may not only not be able to charge it, but you will also charge less and less.

Moreover, there are a large number of copycat chargers in the user's home, which will falsely mark their own charging current, of course, the quality is not very good, and it is normal for the situation that the charge cannot be charged.

Change back to the original, or find a charger with a higher current and try again, and I'm sure everything will be back up.

After checking the charger problem, if your phone still won't charge, then can you try a different charging cable, if it still doesn't work, you can really start to look at the phone itself with suspicion.

Problems with mobile phones. There are many kinds of battery failures, and there are two types of battery failures: damaged cells or damaged control circuits.

Regarding cell damage, the problem is mainly focused on inferior cells.

The life of the battery cell will also lead to the occurrence of the phenomenon of not being charged, and the life of the inferior battery will be consumed faster, if your mobile phone is not used for two months, the battery will not be durable, then eighty percent is to run into a copycat battery.

In another case, the cell itself is fine, but the control circuit is wrong. No matter how long some mobile phones are charged, the battery level will always show 2%, but it will only drop to 1% after one day, which means that the battery cell itself is performing normally, but there is a problem with the circuit used to measure the battery level.
