Short term abuse kills the battery, thats whats to concern yourself with, NOT cycle counts.ĭoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. New from box 2 to 5 cycles, however cycles dont account for or mean anything except in the old age of the battery. So what should the charge level / cycle count be on a new battery for example - how would one find this sort of information out? So you can see the changes of your battery health over time.

Some humans answering questions also sleep a few hours every 24 hours. The board flies by and replies are missed. Youre 100% mistaken, about 40 people or so on this board answering 1000s questions a day. it seems this apple community is somewhat 'sniffy' - and 'stuck up' - treating us plebs like. Peacekeeper just happens to let you run it on a loop so that it acts as a battery test.As suspected - no response. Peacekeeper’s primary purpose is to test web browser performance, so it has much more rigorous tasks that involve rendering videos, 3D graphics, web-based games, and more. Apple says its wireless web tests involve “browsing 25 popular websites,” and the company doesn’t get any more specific than that. The results for this test fell quite short of Apple’s specifications, but to be fair, this test is quite different from the one the company runs. 13-inch Retina MacBook Pro: Up to 10 hours.I used this to test what Apple calls “wireless web” battery life. The second test I ran was the Peacekeeper Universal Browser Test, which has a battery test component. Still, you’re going to be able to watch several movies or maybe even a whole season of “Game of Thrones” on a trans-Pacific flight. The MacBook was the only laptop that didn’t meet its specification, but it was only about 40 minutes short.

13-inch Retina MacBook Pro: Up to 12 hours.
