Why does the mobile phone not charge: Cause 1: The output voltage of the mobile phone charging head is insufficient, and the output voltage and power of the computer charging cannot reach the standard charging voltage and power. This result is that the mobile phone battery cannot be charged, and the charging will also have some impact on the mobile phone hardware; Solution: Use the original charging head, or stop using the mobile phone for a period of time, and wait for the charging to be completed before using it; Reason 2: The capacity of battery aging and failure decreases: lithium batteries are generally used now, and the lithium batteries themselves have a certain service life (mainly based on the number of charges and discharges, the normal use can reach about 500 times, and the capacity decreases proportionally with the increase of the number of times, and ordinary users can generally use about two years); Solution: Since most mobile phones today are designed with non detachable batteries, you need to contact the maintenance station to replace the batteries in this case. Cause 3: Using a brand name charger: users often overcharge and overdischarge due to abnormal use, such as using a brand name mobile phone charger; Solution: Do not use cheap brand chargers. Incomplete protective circuits limited by the cost of such chargers are likely to cause overcharging and damage the battery. It is best to use the original mobile phone for direct charging. The above is the answer to the reason why the mobile phone does not charge. I hope it can help you.
It is recommended to try the following methods: Turn off the machine and take out the battery. Use a cotton swab to wipe the contact point between the battery and the mobile phone. Connect the original charger to the home power supply for charging. Replace the power socket or replace a data cable to connect the charger for charging. If it is impossible to charge with wire charge, replace the battery or use universal charge if conditions permit.If other charging equipment can charge the battery, it may be that your line charging contact is not good. It is recommended to replace it. If the phone can be used normally, it is recommended to back up the data in the phone (such as contacts, multimedia files, etc.) and restore the phone to factory settings.If the problem still exists according to the above method, please take the purchase invoice, warranty card and the machine to the after-sales service center for inspection.
Two questions! The first is the problem of mobile phone cable. You can try another cable! The second is the problem of the mobile phone socket. Blow the dust off and try again!
