Macbook pro 16 inch 96watt power supply limited to 60watt

Hi,


My new macbook pro 16 inch with the 96watt charging brick (and factory included usb-c cable) charges at a limit of 60 watt instead of 94 watt.


When using the macbook heavy it even drained the battery when plugged in.


I reseted the smc, tried different ports, different cables,... for some reason only one thing worked. Letting the battery drain fully, then charging the macbook to 100%. When i then use the macbook under heavy load it stays at 100% when plugged in and charges at up to 94watt speeds. When i unplug, it resets back to 60 watt and hav to start the proces al over again...


This is a screenshot where you can see the 96 watt charger is plugged in and recognized, but limited to 60watt charging.


The next screenshot is from the time i let it drain and charged it back up to 100%. Only then it allowed 94 watt charging.

If you are under a load then being plugged into the mains, having the charger plugged directly to the USBC port.


Your experience seems a bit odd.


I can not discern anything form those screen shots— maybe if you could translate somehow or highlight the point.

Non-the-less I would recommend you Call (800) MY–APPLE (800–692–7753)


or on line https://getsupport.apple.com/

or call AppleCare Support at 1-800-APLCARE.

A similar thread a few days ago was resolved by replacing the Charge cable. The user said their Charge cable was defective.


That could also be caused by using a too-small capacity charge cable.


Remember that all cables are now for specific purposes -- the days when, 'if you plugged in an Apple cable it just worked' are long gone. We are now in the USB-C era, where USB-C is the name of the connector, ONLY, and not a valid name for any cable.
