New MacBooks Take Big Performance Hit With Battery Removed
Wired: Gadget Lab —
Apple's new MacBooks are mighty speedy, but they suffer from a huge performance drop if you remove the battery and use the AC adapter as the sole source of power.
Gearlog's Zach Honig discovered that the MacBook sees a 37-percent drop in speed when running without a battery.
Honig benchmarked a 2.53 GHz MacBook Pro using a multiprocessor test called Cinebench R10. With the battery present, the MacBook Pro turned in a score of 5,549. Without the battery, it scored 3,504.
While this may appear to be a minor issue -- since most ...
Run your MacBook without a battery and throttle the performance
jkOnTheRun —
... I am still trying to get my head around this article on Gearlog that points out that Apple notebooks throttle the CPU performance if you run them plugged in without a battery installed. They discovered this "feature" by accident while performing benchmarks with different types of RAM. They kept seeing different results and then figured out that the benchmarks run on the MacBook Pro while plugged in but without the battery installed consistently clocked in with 37% lower performance. ...

MacBook and MacBook Pro Take a Performance Dive While On AC Power Alone [Apple]
Gizmodo —
... a battery-less Pro a score of only 3,504, while with the battery it scored 5,549. They contacted Apple to find out what's going on, and Apple admitted that the performance difference is intentional, explaining that it "prevents the computer from shutting down if it demands more power than the A/C adapter alone can provide." Sounds a little fishy to me, but it doesn't really matter: Apple took a lot of care with that battery, and if you know what's good for you, you'll leave it be. [Gearlog] ...
MacBook performance drops 37 percent without battery installed
CrunchGear —
... Don’t bother using your MacBook or MacBook Pro without the battery installed unless you’re cool with a huge performance decrease. Gearlog notes that, in the process of doing the thankless task of RAM benchmarks, the MacBook’s performance, as rated using Cinebench, dropped some 37 percent without an installed battery. That is, when plugged into a power outlet without the battery installed—some people do this to extend the life of their battery, having it installed only when necessary—the MacBook suffers quite a bit. ...

... 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. via Gearlog Tags: Apple , battery , Laptops , MacBook , Mobile ...
