2012 Samsung Galaxy Note 10.1 with slow charging issue

I cannot seem to get this device to charge at a decent rate. When plugged in, it only pulls 0.83 A at 5.65 V. I have installed a new battery and have also reset the device, several times, each time it works marginally better for a while, then back to slow charging issues again. I have tried several different Samsung charging units and cords, all with the same outcome, slow charging.

Should I be looking for a deeper issue?

Thanks for your help.
