Phone taking too long to charge, usb port damaged?

I bought this phone used but it looks like new (no scratches, scuffs or anything really). After using it for 2 days I plugged it a micro usb 2 (I don't have the usb 3 coord) to charge the device.
I was using a 2A charger (the one from LG G2) and I noticed it took almost 3 hours to charge from 40% to 100%, isn't that too long?
I also have problems connecting it to my PC since it is always connecting and disconnecting (my Galaxy Nexus also does that but has no problems while charging and it's not too agressive in the pc part so I am not sure if it is from the phone or from the pc).
I've tested with various usb cords... same result

Here's a picture of the port, is everything alright here?

Phantom data taking up storage space

As you can see in this picture (i.imgur.com/Q0ZZdUO.png) my phone's internal storage is about 11 GB, however the combined storage space of everything listed below is less than 6 GB. I know personally that I have not put much of anything onto the internal storage, so what does the phone think is taking up the other 5 GB, and how can I fix it?
I'm using this ROM btw:

Dev Edition not taking OTA

Hello Geeks,

I had a M9 from ATT and then rooted and S-OFF with Dev edition ROM. Today with the OTA, when I try to update, I get a bitmap error that the system is rw.

So in what way will I be able to put the update on my device??

What is taking Samsung so long to update to LP 5.1.1 ?

I heard that LP 5.1.1 is the most stable. We are stuck in 5.0.2 on Note 4. So is my Tab S. So is my Alpha phone. All at 5.0.2

Why is Samsung so slow? I think they might have abandoned us.

Samsung screw up on Note 5 and all the updates are slow.

Its a bad company.
