MacBook Air 13" Mid 2012 battery usage question
Hi everyone,
I've had my MacBook Air for about 9 months now, love this computer!! But, recently I had noticed my battery life lasting for barely 4-5 hours. I visited the Genius Bar and they had said that the battery's charge capacity had dropped down to 90% (had about 280 cycles) which is not good. Cool thing though, they swaped the batteries out for free since I am still under warranty. But with the new battery I'm starting to doubt whether the previous batery dropped charge because of the way I used it. So normally, I use the battery all the way down till about 3%, that's when the battery low message pops up. Now is going from 100% to 3% (sometimes 0%) not the right way to use my battery?
Thanks in advance,
Jatin
