I can assure you that the 9-10 hour estimate for the MBP is optimistic at best, and downright misleading at worst. I'm lucky to get 7 hours if I turn down the brightness and do nothing but browse the web and check email (no video or Outlook, just regular old Apple mail). Any realistic usage scenarios net about 4-5 hours, and any semi-intensive use (IDE open, iMovie, Photoshop, streaming video, etc) will drain the battery in 3.5 hours flat. I'm not the only person with these issues; Marco Arment, Gruber, and the rest of the Apple triumvirs all share the same complaints with regards to the 15" MacBook Pro's battery life. Part of the blame is poor optimization on Apple's part with Turbo Boost, and another just rests on the fact that it's ridiculously hard to drive a high-resolution, bright screen, a powerful processor, and a graphics unit without sacrificing some degree of efficiency.
- rayiner 11y agoI've got a 15" rMBP and regularly get 8-10 hours of browsing, word processing, or light coding. On ArsTechnica's web browsing battery test, the rMBP exceeds 10 hours. Recommended display brightness for standard office conditions is 150 nits. The rMBP goes up to double that, which obviously has a battery life cost. Also Chrome is poorly optimized for Mav, it takes several hours off the total.
- WildUtah 11y ago"nothing but browse the web and check email" Try using Safari instead of Chrome. And check if you're running a lot of Flash. The usual problem is that Chrome is engineered to gorge power with no regard to your battery. Flash, of course, is pure abuse and stupidity. It all disappoints me because I prefer Chrome for its tools. But Google simply doesn't seem to care that it goes overboard on power and RAM drain.
