Battery Life Time

[omarbeh]

I had my MBA for about 4 months and I found couple of days ago that the battery life decreased by about 1 hour with the same usage trend as before. The only thing that I am not sure whether it is the reason or not; is that I live in Egypt, so use a plug adapter for the charger to fit in the wall.

It's not a transformer you're using, it's just an adaptor. And it doesn't really matter.

Your battery seems to be going, though, so contact Apple and when recognised as a problem, you will have to send it in to get the battery replaced. Remember to back up your stuff beforehand.
