So I’ve been spending a fair amount of time reading the initial chatter about Mountain Lion. While it appears to be a mostly solid release, there are those inevitable growing pains that Apple will have to address in the first couple of maintenance updates.
Chief among these is battery life. A fair number of early adopters are reporting significant reductions on a number of Mac note-books. Apple is reportedly investigating the problem, which means they are taking it seriously enough to be considering a solution.
Now power management is not something easily handled, and it may require a lot of field testing to see why these problems are happening, and what sort of solutions are needed. It’s also not the first time Apple has run into such difficulties after an OS update. Last fall, in the days after iOS 5 arrived, users of the iPhone 4 and 4S reported subpar battery life. It required two updates to pretty much set things right, though I gather there may be a small number of users who are still complaining.
