Q: Battery Life Macbook Air
On my 13" Mid 2012 MacBook Air, I had just fully charged the MacBook over-night and I needed to bring it to school. I checked the battery charge and it said "100%" however when I checked the time remaining, it said "1:29". I found this weird and I quit all apps, restarted it and then checked once more. This time it said "4:46". The laptop lasted the whole school day but I had to have only the minimum amount of apps open and the screen brightness on 3. Does anyone know why?
MacBook Air, OS X Yosemite (10.10.5), 13-inch, Mid 2012

Yes. Seems your battery is just fine. Changes in hours left is the usual thing since every change in what the computer is doing causes the time remaining to change. All the time remaining means is that were the computer to keep doing exactly what it is doing at the moment of the reading, then the battery will last that long.
