I received a replacement early 2013 rMBP in late September, due to repeated repairs in my mid 2010 machine - one of the reasons I love Apple. I have been using my desktop machine for the past month or so, and was holding off opening up the new machine until I found out more about the new models. Anyway with no real changes in the new models I booted it all up for the first time, and it's a great machine. Anyway I checked Coconut battery straight away and it told me from the capacity was 100% as expected, with a charge cycle of 2, which I know is normal even for a new machine. I drained the charge that it had out the box, about 75%, until it turned itself off, then gave it a good 'first' charge from the evening into the morning, which was about 15 hours, even though it had finished charging by late evening. I checked Coconut battery again and it's telling me the capacity has already dropped to 98%, I check it 5 minutes later (now) and it's gone up to 99%, is this all normal? The loadcycles is still at 2, and the current charge is 85% in the app but 90% viewing it outside the app in the corner of the screen. I know the app is only estimating, was just concerned to see it drop after one charge?
