Rapid Battery loss
HELP! After 1 hour of usage on my new macbook air, (1 week old ) the battery drops to 50%. What's wrong? Because there's a 5-hour battery built-in so im not so sure
I had this problem too. The solution is not to have all applications open at once. Look at the bottom of your screen and you will see tiny little faint lights in the reflections under the icons. If these are lit they show that the application in question is open, and using up your battery. If you're not using the application, quit it and only run the ones you need. That will make a big difference.
