Power supply not providing enough power for a Macbook Pro 15' Retina
Hi there,
I am discovering a new thing.
When using my macbook Pro 15' Retina Mid 2015 (Processor i7 2,2 GHz 16Gb RAM 256Gb SSD Drive, Iris Pro 1536Mb on macOS High Sierra 10.13.2) quite intensively the power supply does not provide enough and the battery is being used.
For example I start with the battery fully charged and with the original power supply plugged in at all time.
I start encoding videos. I can see the battery percentage decreasing progressively to 90% after 1h of encoding...
Is that Normal?
