    Dunno what word to use but if my battery goes from 75% to 95% in 30 minutes, does it mean that the battery will get fully charged in 2.5 hours?

    Any personal experiences of how long it takes to fully charge a 13" 2011 MBA?

    No it is not linear. At first, it is really fast. Towards the end, it gets slower and slower.
