Lithium Polymer: 46% More Capacity, 0% More Weight

Today Apple is shipping lithium polymer batteries in all of its MacBook Pros. Only the original, white MacBook is offered with a removable battery. Most impressive are the capacities Apple is able to offer thanks to these new batteries.

The table below shows the old and new battery capacities:

  New Lithium Polymer Battery (Integrated)

Old Lithium Ion Battery (Removable)

Increase in Capacity
MacBook Pro 13-inch 58WHr 45WHr 29%
MacBook Pro 15-inch 73WHr 50WHr 46%
MacBook Pro 17-inch 95WHr 68WHr 40%

 

Now there was no 13” MacBook Pro before, so I’m comparing to the old aluminum 13” MacBook. Also, the 17” MacBook Pro was the first and only unibody 17” MacBook Pro so the old battery I’m comparing it to was the previous generation 17” MBP battery.


73Whr?!? Holy crap

The biggest winner is the 15” MacBook Pro, it gains a 46% increase in battery capacity with zero increase in size or weight. The new 15” MacBook Pro is the same size and weight (5.5lbs) as the previous model, it just has a 46% larger battery. Did I mention it’s cheaper too?

    I guess your findings on MacBook Pro battery life should make those who say Macs are only commodity notebooks with a fruit sticker and a higher price think twice. The 15.4" MacBook Pro may not be the fastest 15.4" notebook or the cheapest, but it offers great battery life and light weight without sacrificing too much performance. That's certainly a combination some people would be willing to pay for. Reply

    [EDITED: Pirks, watch your comments please.]

    Summary: I'm glad to see someone showing all the Wintel fanboys that Apple is great. Anand showed them GOOD. Thanks Anand! :)))

    Does it include comments on DailyTech too? Reply

    Nope... we're technically "sister" sites, so essentially we have nothing to do with what they write about. The editing ability (and post deletion ability) is mostly for when people step way over the line... try and keep the comments more professional rather than less - and remove any outright name calling.

    Yep that's why I like reading the comments here. Always quite professional as people leave the Apple/Windows Nvidia/Ati Amd/Intel love hate thingie pretty much alone and are mostly cordial about their biases .. if it's even evident that they have any.

    Did the 15" model you reviewed the battery life on have the optional 9600gt?

    I know apple let you disable it, but it being absent may be more energy efficient than being simply disabled.

    Also what processors do the MBPs run? As apple simply state 2.53 GHz, when there are several mobile chips which run at that speed - the T9400, P9500, P8700.

    Great review.
    Thanks :)
