I'm sorry to cause you any confusion, because there is an electric current passing through the body during charging, and the lithium-ion collision will generate heat, if the mobile phone device is only slightly heated during the charging process, it is a normal phenomenon.

If the device has serious heating during mobile phone charging, it is recommended that you verify whether you are using a non-standard or defective data cable, and if so, it is recommended that you replace the standard charger and data cable. If you have used the standard data cable and still have serious heating, it is recommended that you bring the warranty card or invoice to contact the local maintenance site to test the battery, charging circuit, and charger, which may be caused by charging circuit failure, battery aging, and unstable input current and voltage of the charger. Inquire about authorized maintenance sites on the official website.

Abnormal. It feels hot to touch the plastic shell, and the electronic components inside must have a high temperature and a short lifespan. It is normal to feel slightly warm.

The mobile phone responds slowly, and the problem that often occurs is that the program is installed and opened too much, it is recommended that you often clean up the infrequently used applications in the mobile phone (system settings - applications - all - find some infrequently used applications - uninstall), or some applications occupy too many resources or system-level problems, you can often use the one-click cleaning function of Lesafe to close the background program and organize the redundant files of the system. If the above operations cannot be improved, you can back up the data and restore it to factory settings, and then install less software as needed to keep the system clean and tidy, so that it can be used smoothly.

If it cannot be improved after repeated optimization, it is recommended that you take the time to bring the warranty card or invoice to the local repair site for system reinstallation. Because the mobile phone system is like the computer system, if it is used for a long time, the role of optimization software will not be too obvious, and the system needs to be reinstalled to improve the usage. Inquire about authorized maintenance sites on the official website.

Would it be better if you changed the charger and tried it?

Use direct charging fast, use up the electricity first, then fully charge, take turns a few times, and it will be good in the end.

Hello, I'm sorry for the inconvenience caused by the rough cavity.

Based on your feedback, we recommend that you perform the following methods:

2.It is recommended that you can replace the charging cable and power adapter if possible, if it can be improved after replacement, you can infer that the accessory is abnormal;

3.If you have other batteries, it is recommended to try to replace them, and it is not ruled out that the battery is caused by the failure of Wuyan Town.
