Also is it taking like more than 1.5 hours to charge the mobile to full capacity? Mine is very slow in terms of charging. Don't know what fast charging is doing.
It also gets heated up a little while fast charging. So I'm not sure if it's with everyone or is it just me.
It's completely normal to get heated up when fast charging. If you turn the fast charging off it won't do that. It says on the bottom of the battery settings page that the device may become hot when using the fast cable charging.
