Nokia 6300 my cell phone shows charging on screen but still not charging cell phone battery. can you suggest me solution of charging battery?

Hello,

I suggest you remove the battery and test it with another similar phone to see if it will charge, if it does, it means the battery is ok but if it did not, it means the battery is bad and need to be change.

But if the battery is good, it means the charging port is bad, all you need to do is to change your charging port because that is the next action place to check.

Looking at this two areas should profile a solution to your problem.

Thanks and wish you best of luck.
