i think the idea is not to have it plugged in to power while using it, only charge overnight

That's a fine intention, but I sometimes like to compile code or use Chrome.

  I don't think that you're the target audience - along with the majority of us here.

    This seems to be true, but then I wonder who they expect to develop the software for their target audience?

        I'm a web developer and I can say that the new MacBook doesn't make me want to buy it because: 1. 12" is a weird size for me. I'd prefer 15" Pro edition. 2. One connector isn't enough, even with the adapter, I'd need more.

    Then who is the target audience? Casual Facebook users will probably install Flash the moment they unbox the machine.

      Students and teachers are the target audience. Salespeople are. Business people are. These people all have serious computing needs that are better met by an ultraportable device with long battery life than by anything that has more horsepower or more ports. Casual Facebook users are not a target audience for anything, because almost everybody is a casual facebook user, including people who do 3D animation or need to compile huge codebases.

        The grandparent post was talking about all-day battery life, not about horsepower or ports. But I don't see that being realistic, yet, because (a) the new MacBook has less battery life than the 13" Air, (b) OS X is messier than iOS (system daemons love to run at 100% CPU once in a while), (c) as you said, almost everyone is a casual Facebook user and runs terrible crap like Flash. (iOS is at an advantage here again) But yeah, it is a great device for people who only open their laptops occasionally and can recharge at night.

  Well it's possible that one of these days Google will fix the huge battery drain Chrome causes on OSX.....

With the limited number of charge-discharge cycles that even LiPo batteries have (typically estimated at ~500), that means you'd be replacing the machine within its depreciation lifetime if you fully — or even mostly — discharged it daily. Oh, wait. That benefits Apple, too...

  Did Apple change from 80% battery life after 1000 cycles?
  - rosser 12y ago
    I'm seeing reports of Apple laptop batteries barely lasting an hour after 400 cycles, having 75% of their rated capacity after 900, and having 50% after 1100. I think usage pattern probably matters far more than the strict cycle count. Specifically, "all-day" usage appears to correlate strongly with battery capacity falling off more sharply as cycle count increases — admittedly, based on user-reported behavior that I could find on the web with as much time as I can spare this afternoon to faff about on the matter.

      They're not that bad in my experience. I'm at 1476 cycles and still have 87% of my capacity remaining.

      Yeah, the number of charge cycles you get out of lithium ion batteries is known to be affected by how deeply you discharge them.
- rayiner 12y ago
  Macbook batteries are rated at 80% after 1,000 cycles. And battery replacement on an MBA is a $129 ($199 for an MBP) service that they can do at the Apple Store while you wait. Lenovo wants $139 for a replacement battery for a T4xx of similar capacity.
