Carved from a single block of aluminum, the new unibody enclosure is slim and streamlined, making this MacBook Pro the worlds thinnest and lightest 17-inch notebook just 0.98 inch thin and 6.6 pounds.
But its not just for looks. The rigid construction of the unibody also makes MacBook Pro more durable than ever. So you can throw it in your bag and pull it out at a photo shoot, in a hotel room, or on location without a second thought.
The longest-lasting Mac notebook battery ever.
The battery in the new 17-inch MacBook Pro lasts up to 8 hours on a single charge1 and can be recharged up to 1000 times2 compared with only 200 to 300 times for typical notebooks.
To do this, Apple engineers custom-designed lithium-polymer cells to create the largest possible battery, then they went even further:
They built the battery right into the computer, eliminating the space-consuming mechanisms and housings that standard removable batteries require. The result is a battery thats 40 percent bigger than the previous generation and offers up to 8 hours of wireless productivity on a single charge all in a notebook thats less than an inch thin, weighs just 6.6 pounds,3 and remains the same price as the previous-generation model.
But building a battery that lasts up to 8 hours is only part of the story. Giving it a lifespan of up to 1000 recharges required breakthroughs in battery technology.
Apple electro-chemists developed advanced chemistry that maintains the batterys charging capabilities longer than ever. And while most notebooks wear down their batteries by charging them at a constant rate, the 17-inch MacBook Pro takes a different approach.
Using an Apple-developed technology called Adaptive Charging, a microchip on the battery constantly communicates with the computer to determine the optimal way to charge its cells, adjusting the current up and down depending on a variety of conditions. Combined, these advancements offer a dramatic improvement in battery lifespan: more than three times the lifespan of typical notebook batteries up to five years.
A battery that lasts up to 8 hours. A high-resolution widescreen display. Now everything in the 17-inch MacBook Pro is huge. Except its size and weight.
