Hi folks, after updating to 10.7.1, the battery life of my MBA 11 i7/256GB has improved almost 15%. From 235 minutes (browsing with safari and no flash installed, email, and coding) I am now getting between 270-280 minutes consistently. I have gone through 2 and a half cycles since yesterday and both full cycles show the improvement. I also noticed a small temperature decrease under the described conditions. EDIT: My screen brightness is set to 4 bars and bluetooth is off. Is anyone else experiencing better battery life after the update? If so, please post your regular usage times. It seems 10.7.1 has been a more substantial update than I thought. Cheers.
