The new MBA should last 12 hours under "normal" use, whatever Apple defines as normal. If you do everything possible to save energy (lowest screen brightness, WiFi off, Bluetooth off, no apps wasting energy, nothing reading/writing SSD), you should get more than that. If you are typing a document, and spend twenty seconds thinking about what to type next, that kind of number shouldn't be unusual. (Just checked: The battery time changes very slowly, so not typing for 20 seconds won't make a difference, but doing very little for 20 minutes will).From a full charge, sitting outside writing a document.
screen is 6 clicks off the highest, key board light on two clicks from lowest, blue tooth off, wifi on, 2 tabs open in safari, mail open, i message open, few other small apps.Guys, we need more information for battery tests. What's your screen brightness setting at? I see WiFi is on and bluetooth is off. Anything else to note?
I think people are getting OCD over battery life. We are at the point where battery life outlasts most humans for a full day of use (unless that particular human has no life at all outside of the internet). Stop fretting and just enjoy the thing.Guys, we need more information for battery tests. What's your screen brightness setting at? I see WiFi is on and bluetooth is off. Anything else to note?
How are you getting that much life out of a machine that's supposed to have around 7 hours? Just wonderingThat's nothing. My 2010 13" C2D MBA gets 18:42 battery life, sometimes 20:00. Looks like Haswell still has a bit further to go to meet the 2010 benchmark! See image....
I use CoolBook and keep brightness down to 3rd bar. Note, this shot was taken coming out of standby, so I'm joking around a little bit. But this machine will actually get over 10+ hours, as verified by Anand.How are you getting that much life out of a machine that's supposed to have around 7 hours? Just wondering
Just to add, imagine how long the 2013 MBAs will run with Mavericks installed! My Air gained a lot of battery life when I installed Mavericks.
I thought Coolbook didn't support the newest Intel CPUs and Lion and onwards.Can you share a little more about your use of CoolBook?
