Thread starter Amie Start date Aug 20, Amie Mac Convert for Life Aug 20, Quoted from Apple's support website: In addition, Adaptive Charging reduces the wear and tear on the battery giving it a lifespan of up to 5 years. Five years? Is there anyone with a MBA who can actually confirm this via personal experience?

That seems like a looooooong time! My old iBook G4 battery had to be replaced about every 2 years. I have a model MBA now, for reference. If I use it every day just for Internet surfing, no major programs , can I still expect the battery life span to last 5 years? DeltaMac Tech Aug 20, Apple significantly changed the batteries in all their laptops 2 to 2 years ago. First, you will notice that Apple before would use the figure of full charge cycles, as an estimate of the life of the battery. Using a rough guess of full charge cycles a year, then it's easy to see 2 or 3 years as a potential expected battery life something like your experience The number that Apple uses NOW is 1, full charge cycles.
So - in simple numbers, that's something like 3 times as long. Then, you have real time - no one at the consumer level has had one of Apple's new batteries for 5 years yet. There's a couple of years before the real-time reports would be available.
Your Answer
Shorter life means that you charge your MBA up completely, then use it off charger until it runs completely down each day. And, you can use your MBA for quite a while longer, per charge, than you could ever do with your old iBook G4. Amie Mac Convert for Life Aug 21, Delta, thank you! You always reply to my posts! And you explain it so well. Thanks for the reply.
Determine battery cycle count for Mac notebooks
I'll be sure to check back in All screen savers are disabled, but the hard drive is allowed to go to sleep if there's no disk activity. The wireless connection is enabled and connected to a local access point less than 20 feet away. This test represents the longest battery life you can achieve on the platform while doing minimal work.
The results here are comparable to what you'd see typing a document in TextEdit or reading documents. Last year's inch Air did amazingly well in our light web browsing battery life test, shattering even Apple's own expectations for the system. The new inch MacBook Air doesn't fare as well. While the new Air still delivers a respectable 6. If you're used to using your Air as a glorified typewriter, expect less battery life with the new model. I'm not entirely sure why the inch MacBook Air did so well in our test.
There was something unique about that model that has since been lost.

The new 11 also loses out in the battery life department, but the drop isn't nearly as significant. I should add that these results do generally support Apple's battery life claims for the MacBook Air. Apple lists the 13 as having up to 7 hours of battery life and the 11 with up to 5 hours. The test here has three Safari windows open, each browsing a set of web pages with between 1—4 animated flash ads per page, at the same time. Each page forwards onto the next after about 20 seconds.
As always, the displays are set as close to one another as possible, audio at two bars, screensaver disabled and the hard drive is allowed to go to sleep if idle. Our light web browsing test is really the absolute best case scenario for battery life under OS X. I often use the term glorified typewriter because that's typically when you see these numbers: For a writer, that's a valid usage model but for the majority of the population you'll be doing a bit more. This is where our Flash Web Browsing test comes in to play. Here the numbers drop and the gap between last year's MBAs and the new systems shrinks to basically nothing.
You can get around 5. The speakers located beneath the keyboard on the inch Air certainly don't project booming sound, but the audio quality is better than you might expect from such a svelte design. However, we kept the volume at about 80 percent to avoid harshness. This includes Apple's new Thunderbolt display, which doubles as a docking station.
When you're not attaching a Thunderbolt device to the Air, this connector doubles as a DisplayPort, which you can use to hook up a high-res display duh but also adapters for Ethernet and FireWire The right side of the inch Air also includes a SD card slot--something the inch model lacks--along with a USB port. We wish memory cards inserted further into the chassis, but it's not a big deal.
The magnetic power connector, a second USB port, and headphone jack line the left side of the notebook. Just as with the inch Air, the inch model features a high-quality VGA webcam for conducting FaceTime video chats and calling friends over Skype.
