Not charging via USB - PC lead

[Guest Argonaut]

S5  model SM-G900F  running 5.0 

 

While it charges OK from AC adapter … when I connect it via a USB lead to a PC I have issues.

The phone status shows:

Status: Charging

Plugged; True

Yet continues to discharge …  for example watching phone now… its plugged into PC  at this point at it has dropped form 51% to 49% since plugging into the PC.

Putting phone into flight mode while slowing down discharge rate, still does not allow it to charge.

 

The PC port & cable are known to be good as they charge my S4 with no problem.
