I recently got a 13.3 with 4 gigs of ram, and lemme preface this by saying that it is a phenomenal computer. I have an ipad, and using airdisplay to do wireless dual monitors is a sight to behold. However, I've noticed a rather disturbing battery drain on my MBA. It came at about 86% charged, and after a full charge I've noticed fairly significant battery drain. I didn't time anything, but it hit ~50% battery after an evening of really sparse usage (brightness 50%, wifi on, no mp3s playing, click2flash installed and no flash content used). I figured it was first day jitters and recharged it to full, then watched a single video on hulu with flash enabled and full screened at the same 50% brightness with 80% sound. After a 3 minute video, I was already down to 97%. Then I searched online for average battery life, finding out that it was capable of handling 11.2 hours of light browsing usage from anandtech. This took a max of an additional 10 minutes, which dropped the battery to 95% (no flash was on and hulu was closed). I shut the lid and opened it again this morning after 8 hours of standby and it was at 94%. Is anybody else experiencing similar battery issues? I don't feel very confident that this MBA can last half the day if I was using it non stop, let alone a full 11.2 hours. I want to know if this is a battery defect on my own laptop and warrants a replacement, or if this is the status quo. In fact, in the time it took me to type this post on my desktop computer, my macbook air has dropped down another % to 93% with absolutely nothing running and no active use.
