If you can't turn on it when it's fully charged, it should be because of the quality of the phone's battery.

If you can't turn on the phone when it's fully charged, it should be that there is something wrong with the quality of the phone's battery. It is recommended to try a new battery, you can use an authentic original phone battery. If it can be turned on and used normally after replacing the battery, it means that the mobile phone itself is fine, mainly because the previous mobile phone battery is not working.

Maintenance of the mobile phone battery:

1. First of all, don't let your phone be exposed to high temperatures for a long time. Whether it's sun exposure, high indoor temperature, or hot fuselage caused by playing games.

2. In a sense, the reason why playing games while charging is not good for the battery is not because of normal battery loss, but because of the battery loss caused by the double heating of charging and heating.

3. Try to charge the battery before it is less than 20%. I often see friends around me who still have 10% or even less electricity left, and they are still chatting about WeChat and watching**. I was even very proud: it's okay, I can stick to my 10% electricity until I get home.

4. For many of our friends who go to work, we should develop the habit of charging at hand. It is advisable to control it at 20 to 80 percent.

5. Finally, do not use universal chargers or inferior and unqualified third-party chargers. <>

There may be many reasons why the mobile phone cannot be turned on when it is fully charged, and the following will introduce them for you one by one.

First of all, it may be caused by the inaccurate display of the phone's battery level. Sometimes our phones are only 90% or less charged when they show 100% power. When we tried to turn on the phone at this time, the phone would not turn on due to low battery.

In this case, we can charge it for a little longer, or use the charger to replug and let the phone re-read the battery data.

Secondly, it may be caused by the aging of the battery. After a period of sleepy use, the battery of the mobile phone will continue to drop until it cannot be fully charged. When our mobile phone battery ages to a certain extent and cannot be fully charged, it may not turn on.

At this time, we recommend replacing the phone battery.

In addition, it may be caused by a malfunction of the phone's hardware. During use, there may be problems with the hardware parts of the phone, resulting in the phone not being able to turn on. For example, a broken screen, a damaged wheelboard, a damaged power supply, and other situations can cause the phone to fail to turn on.

At this time, we recommend going to a professional mobile phone repair shop for repair.

Finally, it could be caused by a system crash. When our mobile phone system crashes, sometimes it won't turn on. In this case, we can try to reset or update the phone's system.

If we are not sure how to reset or update the system, we can consult a professional technical support staff for help.

In summary, the phone cannot be turned on when it is fully charged, which may be caused by a variety of reasons, such as inaccurate battery display, aging battery, hardware failure, or system crash. If we encounter this problem, we can take different solutions depending on the actual situation. <>
