PSA: Using a 60W MagSafe Charger with rMBP 15" can actually drain battery


so today doing pretty cpu intensive stuff on macbook , had 60w adapter me. macbook plugged in , supposedly charging (it had green light @ start). noticed progressed through hours, laptop started needed charging. macbook drained down 20% before stopped using , let charge again. i'm guessing isn't battery mean can still use laptop longer time before. charging indicator showed charging time of 20:00 (20 hours) ridiculous. think normal behaviour dgpu , other aspects of machine use more 60w provided , require more, 85w provide. 85w not included faster charge out of usability. i'll have purchase more now!

(this discussed way before me in multiple threads thought i'd share experience didn't know) screen shot 2015-12-08 @ 01.06.14.png
