Presented here are the top five 2011 laptops for battery life, as measured by our in-house video playback battery drain test. It’s easy to guess that Apple makes at least one appearance on this list, but there are some surprises as well. Note that these rankings only include integrated batteries, not secondary add-on slice batteries. If we included those, systems such as Sony’s Vaio Z, with a combined 634 minutes between its internal battery and a $150 add-on slice battery together, would make the list.

If we included those, systems such as Sony’s Vaio Z, with a combined 634 minutes between its internal battery and a $150 (£96) add-on slice battery together, would make the list.
5. Apple MacBook Pro Winter/Spring 2011 (2.7GHz Core i7, 13-inch) With a boost from Intel’s Core i-series CPUs and the switch from Nvidia graphics to Intel’s built-in HD3000, this version of the popular MacBook Pro ran for 418 minutes. The good: CPU updates offer big leaps in performance; phenomenal battery life; excellent ergonomics, keyboard, and large, smooth, multitouch clickpad are still among the best available; 720p HD Webcam.

The bad: Graphics performance is slightly worse than last year’s 13-inch Pro; 13-inch screen resolution still low compared with the MacBook Air; Thunderbolt port still an unknown until accessories become available; limited upgrade options; expensive; no HDMI or Blu-ray. The bottom line: Despite retaining the same price and look as last year’s model, the new 13-inch MacBook Pro’s significant CPU updates and fantastic battery life make it one of the top laptops we’ve reviewed, provided you can live with passable integrated graphics.
4. Toshiba Portege R835 This popular, reasonably priced 13-inch laptop also managed to deliver awesome battery life, running for 421 minutes. The good: With a new Intel Core i5 CPU, sharp design, and nearly all-day battery life, the Toshiba Portege R835 is a smartly priced alternative to the 13-inch MacBook Pro. The bad: Intel’s integrated graphics are better than they used to be, but still not gamer-friendly, and features such as Bluetooth and mobile broadband are missing from some configs. There’s no Blu-ray option (only DVD), and the speakers are somewhat anemic. The bottom line:Excellent battery life, a light weight, and great pricing make the Toshiba Portege R835 hard to beat, even in the highly competitive 13-inch laptop category.

3. Apple MacBook Pro Winter/Spring 2011 (2.2GHz Core i7, 15-inch)
2. Lenovo ThinkPad T420 (2.5GHz Core i5)
Another appearance by Apple, this time with the larger 15-inch version of the Pro, which ran for 425 minutes. The good: Powerful updates to the CPU and GPU; excellent Apple battery life; still the best touch pad and gesture controls of any laptop. The bad: Upgrades can get expensive; Thunderbolt is an unproven technology with as-yet no compatible products; still no dedicated HDMI, Blu-ray, or other wished-for options.

The bottom line: It’s a hefty investment, but the combination of new high-end Intel processor options and AMD graphics makes the 15-inch MacBook Pro an all-around powerhouse, with the new Thunderbolt I/O port as an added bonus. After a now-customary period of rumors, leaks, and anecdotal evidence, Apple’s new generation of MacBook Pro laptops has arrived. And though these new models may look the same as the ones they replace, the changes under the hood are some of the most far-reaching in the history of the MacBook Pro brand.
Lenovo’s ThinkPad business laptop line is known for its excellent quality, superior keyboards, and often, very good battery life. This recent update (being reviewed at the time of writing) to the very common ThinkPad T20 turned in one of thebest battery life scores of the year at 442 minutes.
1. HP Pavilion dv7-6b55dx Pulling off something of an upset, the longest-lasting laptop of 2011 in our test was the HP Pavilion dv7. Few large laptops actually take advantage of the bigger footprint of a desktop replacement laptop to pack in a gigantic, powerful battery, but laptops tester Julie Rivera explains that this particular HP configuration “had a huge 100WHr, nine-cell battery”, that ran for a very impressive 513 minutes. The good: The HP Pavilion dv7-6b55dx is a nicelooking big-screen laptop with long battery life and very good performance for the money.

The bad: The dv7s screen is low-resolution for its size and its integrated graphics drag down the performance some. The bottom line: If you’re looking for a lot of screen real estate and enough power for work and play, the HP Pavilion dv7-6b55dx is a good place to start.
