Share some issues about mobile phone fast charging [Copy link]

 

I have been having problems with fast charging recently. I have a Xiaomi phone and I suspect that the fast charging chip has a problem. My phone is A and my partner's phone is B. The phenomenon is as follows:

When mobile phone A is charged with an 18W fast charging adapter, it sometimes cannot enter the fast charging mode, and the slow charging mode is also extremely slow, about 1% in ten minutes. After unplugging and plugging, it returns to normal fast charging.

Mobile phone B uses 27W and 18W fast charging adapters. When plugged into the charger, the charging pop-up window is displayed for one second, and then it shows that it has entered the fast charging state. The fast charging interface is displayed for less than one second, and the phone enters the uncharged state (the battery is too low and there is no charging icon). I began to suspect that it was a problem with the adapter, so I changed to another adapter, and the result was the same problem. Then I suspected that the charging port was loose, but the charging port was loose, and the Type C port should be disconnected from time to time, but it didn't. Finally, I felt that there was a problem with the fast charging chip or the charging program, so I restarted it and the problem was solved after restarting.

Mobile phone A has been used for 2 years, and mobile phone B has been used for 1 year and 9 months.

Everyone is welcome to discuss and share the problems you encounter with fast charging.

Xiaomi phones are indeed cost-effective, but they also have to bear the problem of poor quality control. Based on the experience of my colleagues, it is normal to have problems after using them for more than 2 years.

Yes, I had one before which I used for two years and it had the problem of not being able to connect to the wifi.

Many mobile phones' fast charging is still customized based on the standard protocol, and only their own can achieve the highest

Yes, basically I change my phone every 2 to 3 years.

The power used is not very high, after all, it is only 18W, which is not very fast and can be achieved using standard protocols.

Haha, not really. I just didn't do a good job of cooling down.

It is said that you should use the original charger, such as 18W, but sometimes when you need a power bank to continue charging, the wattage is insufficient. Will it damage the phone if you continue to charge it?
