When the battery of the mobile phone is exhausted and the charger is just plugged in, red lightning may be displayed. This is because the remaining power of the battery is basically exhausted, and it needs to be continuously charged for a period of time before trying to turn on the battery.

Charger problem

If this display is still displayed after charging for a long time, it may be that there is something wrong with the battery and it cannot be charged normally. At this time, you can try to replace other chargers or data cables to see if it can solve the problem.

Charger loss

Excessive charger loss may also lead to charging failure. In this case, replacing a new charger or data cable may solve this problem.

Clean the charging port

Don't forget to check whether there is too much dust in the charging port of the mobile phone, which will also affect the charging effect. You can use appropriate tools to clean the dust from the charging port under the mobile phone to make charging smoother.
