A good laptop should last at least 5 hours on a charge. A great one will give you nearly a full workday’s worth of power for surfing the web, checking e-mail and social networking updates, also getting other stuff done. And this is the longest-lasting laptop list. All of these machines can surf the web continuously with the screen on 40 percent brightness (about the default level when you unplug a notebook) for at least that amount of time.
The longest-lasting laptop list has something for everyone, from a $289 netbook to a premium business ultraportable whose 9-cell battery and optional battery slice combined to last an epic 20+ hours. Want to work and play all day without having to hunt for an outlet? Read on.
Samsung's updated 10-inch netbook continues to beat the competition with an improved touchpad and more than 7 hours of battery life. Durability and nearly 10 hours of battery life make the Panasonic Toughbook S9 a solid choice for the most demanding road warriors. A fast Core i5 processor, well-designed clickpad, and epic endurance of up to 20 hours help the 12-inch Lenovo ThinkPad X220 rise to the top. This ultraportable delivers style, graphics punch, and nearly 8 hours of battery life for a reasonable price. Packed with cutting-edge technologies, the latest MacBook Pro is one of the most powerful and long-lasting 15-inch notebooks money can buy. For just $299, this netbook offers 7 hours and 32 minutes of battery life, a solid keyboard, and multiple color options. HP's netbook for older students provides quality audio, a comfy keyboard, and 8.5 hours of endurance at a low price. The most well-rounded 13-inch notebook gets a serious speed boost and lasts even longer on a charge than its predecessor. This 14-inch business notebook has a stylish aluminum and soft touch chassis that's equally at home in the boardroom and the coffee shop. Better still, the Latitude E6420 lasted nearly 9 hours (8:59) with an extended battery.
