Immediately I updated ny phone to UI 7, the battery display is at 0%. My charger is plugged in right now, and it's not indicating that it's charging. Just 0%.

In the settings, I have run a diagnostic test twice, I passed the charging test, but my phone is not charging!.

This is really frustrating as I have to keep my phone connected to the charger, because I don't know how many percent  my phone is at presently. 

 Someone please help
