My Samsung A51 is having a Battery storage problem

[punno7]

My battery is not filling up and even not showing "fast charging"  It is showing Cabel Charging.  Although I have attached my Samsung adapter. 

What has happened with my cell. Please somebody help me.

Go to battery settings and make sure the fast charging option is ON
