That said, you really don’t need the better performance of the 9600M GT while watching a movie. Whether you know it or not, certain behaviors such as extensive multitasking or using resource-hungry apps. Habits can make or break your MacBook battery life. You’ll barely be able to watch an entire movie in that amount of time. Variations in temperature, usage, and settings can have a significant impact, and should always be considered before any potential hardware issues. Using the 9600M GT graphics card, the 2.53GHz MacBook Pro lasted 2 hours, 12 minutes, while the 2.4GHz MacBook Pro lasted 2 hours, 18 minutes. While watching a movie, you can expect battery life of roughly half of those projected times. If there is a problem with your battery, the Condition entry (which shows Normal in our example) will display something like Service Battery. The battery doesn’t need to be replaced yet, but it probably will need to be done later this year. We tested all of the latest MacBooks the MacBook Air, 13-inch MacBook Pro models and latest MacBook Pro models to help you find the right Apple laptop for you. Instead, those projected times likely are the results of tests that were not as demanding on the computer, like word-processing or Web browsing. The MacBook in our example has a cycle count of 695. We’re guessing that he didn’t expect users to replicate those times while playing DVDs. At the MacBook unveiling last week, Steve Jobs boasted that with the MacBook Pro’s Nvidia GeForce 9400M graphics card enabled you could achieve up to 5 hours of battery life, and 4 hours with the GeForce 9600M (the same graphics subsystem in the new MacBook). Since the two new Macbook Pro models each have a pair of graphics cards, we ran the battery life test using each one, resulting two battery life scores for each MacBook Pro. In terms of battery life, we found that the white MacBook could play a QuickTime movie at full brightness for three hours and 22 minutes, 38 minutes longer than the aluminum MacBook and 28 minutes longer than the MacBook Pro, when the pro system was set to use its battery-saving lower powered graphics.
