can't get my MBP to read %100 full charge

[iapplelove]

2012 mbp classic i was thinking it's the same when my iphone and ipad read 99% fully charged that the battery wants a complete cycle so i tried that.

let the machine go all the way to 5% then plugged the charger in over night and still at 99%

battery life has been amazing even though it's only 2 weeks old but any suggestions ? thanks

It is quite normal for the MBP to take longer to charge from 95% to 100%.

It is also not necessary to calibrate new MBPs, just use it on battery every once in a while.

It's nothing to worry about, there is a 3% error on the meter anyway, but you could try re-setting the SMC :

It might then show 100% after charging, but it's not an issue unless it really starts falling off the cliff...My MBA (2011) shows 94% on Coconut battery, but 100 on the built in meter...Probably about right given the age of my Air and the use it gets.

I'm gonna try some of the suggestions and try not to think about it
