Apple Says MacBook and MacBook Pro Battery Life Has Improved Slightly

UPDATE : We ’ve been seek to understand the new Apple Macbook Pro assault and battery life ratings compared to the old models . It ’s been hard to measure generational differences because Apple is now test using a more challenging battery bench mark , while improve the efficiency of the new machines via Penryn chips and light-emitting diode backlights . Is it a laundry , then ? Not quite . We just get comparative numbers between the previous and current generation notebook from Apple . They read as follows : Macbooks and Macbook Pros have 30 - 45 minutes more life than the former generation using the same Wireless Web test . With light-emitting diode backlighting , the numbers jump to an hour . Note that the 17 - inch notebook computer is not received with an LED backlit LCD , so those are not the estimates give . last , while Apple ’s trial is surd than it used to be , as we saw in the Air , the battery life story you or I will get on these machines will likely be even less . ( The battery claim in the previous generation were much higher because the old psychometric test was basically type on a text editor with Wi - Fi off , which obviously inflate previous stamp battery life approximate beyond reason . )

antecedently ( and depreciated ):

I just spoke with Apple and found out why the novel test numbers are down in the mouth when in fact , the actual absolute assault and battery aliveness in these modelling are higher . It has to do with their examination methodology . or else of reporting the stamp battery life as the longest of three tests ( one test being DVD playback , one trial being standard Wi - Fi usage and web browsing , and one test being absolute power delivery manner doing just Text Editing ) , Apple ’s just reporting the middle psychometric test , which approximates average usage much well than the other two . antecedently , they account numbers for the unlikely scenario that you ’d just be editing a text written document while not connect to the internet . If you go the same trial run in the three models , the newest laptops would actually value higher than before , says Apple . – Jason Chen

Before that ( and depreciate ):

The battery life of thenew MacBooks and the MacBook Pro 17″has dropped dramatically in the novel rescript . From being the top battery performing artist with 5.75 hours , the 2.6GHz MacBook Pro 17″ has fallen to 4.5 hours . There are some explanations , but none of them can explain the change because the numeral do n’t add up :

First is Apple ’s unexampled “ Wireless Productivity ” battery life . agree to Apple , this measures the battery living under distinctive Wi - Fi role , browsing web pages , ferment with mail and other cyberspace - refer applications . It seems like if Apple is now being a lot more buttoned-down and hard-and-fast in their electric battery performance trial . But while this may explain the drop , it does n’t seem that simple .

The MacBook Pro 15 battery liveliness , for illustration , remains unchanged across all CPU speeds even with the new battery trial method acting . Apple sources point out that the use of LED screen backlighting saves about 30 minutes of barrage fire life . But is that enough to recompense against the drop in battery life of the MacBook Pro 17 ?
