We have some bad news for new MacBook and MacBook Pro owners. It looks like they will suffer if you happen to take out the battery. AC power only will not suffice to get the job done properly. So instead of trying to preserve your battery’s life by removing it from the laptop simply leave it be. You’re going to get a new laptop in the future anyways.

Here are some facts: processor performance is 37% lower on a MacBook Pro on AC only. And Apple confirms all of that and it seems it’s intentioanl. That way the computer won’t shout down if it demands more power than what the AC adapter can provide.
