Not getting even close to 10 hours on MBP 13"(late 2010) Hi, I have a MBP 13" 2.4hz/OSX 10.6.6 purchased 14 weeks ago and I am not getting anywhere near the supposed 10-hour battery life. For example, I was browsing using google Chrome over a wi-fi connection at home for about 20-25 minutes, used Facetime app for 3 minutes, and then kept the laptop in sleep mode for about 5 hours. Screen brightness was half-way and keyboard backlight was at the lowest setting(one bar). Battery % meter is now 76%. Just want to see how many hours you are getting from: 1) web browsing using wi-fi card 2) web browsing using a mobile broadband card(& airport off) 3) processing image files using applications like Adobe Lightroom I usually get about 3-5 hours browsing the web using wi-fi or aircard. I was surprised that the battery drain using wi-fi and a verizon mobile broadband card(USB760) were quite similar. My broadband card usually killed the battery faster on older Dell laptop. Coconut battery app states I have completed 25 battery load cycles and current max charge now is 5589mah out of 5770maH design capacity. This report has similar numbers from April 2010. http://www.cultofmac.com/macworlds-1...ur-hours/39634 Do your numbers compare? I was hoping I wouldn't have to carry a charger in my bag. I ran down the battery this month to about 10% as suggested by Apple.
