Really an interesting article to be read by all Apple Product Lovers.
Exclusively for MacBook Lovers.
I just spoke with Apple and found out why the new test numbers are lower when in fact, the actual absolute battery life in these models are higher. It has to do with their testing
methodology. Instead of reporting the battery life as the longest of three tests (one test
being DVD playback, one test being standard Wi-Fi usage and web browsing, and one test being absolute power saving mode doing just Text Editing), Apple’s just reporting the middle test, which approximates average usage much better than the other two. Previously, they reported numbers for the unlikely scenario that you’d just be editing a text document while not connected to the internet. If you ran the same tests in the three models, the newest laptops would actually rate higher than before, says Apple. – Jason Chen
