    90 minutes ago my MacBook was at 3%. Now it's at 100%.

    Pretty impressive I have to say.

    Always good when a device charges so quickly, and also when it lasts so long on a full charge. :)

    So how long does it take with the new 13" rMBP?

    I agree. Maybe the terraced batteries are more efficient at taking a charge. It'd make sense if they're separate cells in there vs the old one was segmented cells that the new method would charge more rapidly. Or maybe the USB-C is more efficient as a charge mechanism than the loss that occurs with a magsafe connector?

    Either way, I agree! It's great, and fast!

    yep, I timed it and a handy rule of thumb is 1% a minute.

    (or 60% in 60 mins)

    Are you really talking about the same computer? My rMB takes 4 to 5 hours to fully charge!

    Are you using the computer while you're charging?

    I always am, though. Even so, running minimal programs still demands 4-5 hours to fully charge. Mine is a SG base model.

    Charging batteries cause heat. Running the computer causes heat. Mac laptops will prioritize thermal budget to running the laptop over charging it. Thus, charging current is reduced in order to reduce heat generated by charging the batteries in order to reduce CPU throttling.

    UK charger?

    Not sure that will make a difference though.
