You can never be too rich, too thin or have too much battery life. Your phone, tablet or laptop can have a gorgeous screen, stunning design and powerful performance, but when it runs out of juice at 2 p.m., it will be the ugliest gadget you’ve ever seen. That’s why LAPTOP puts every device we test through a rigorous endurance test where we turn the brightness to a usable 40 percent, connect it to the Internet via Wi-Fi or 4G (for phones) and make it surf the Web until it dies.
Not a fan of carrying your charger? We’ve tested a number of gadgets with strong endurance during the past 12 months. From a tablet that lasts more than 12 hours to a laptop that can keep going through a trans-Pacific flight, these are the 13 longest-lasting mobile tech products of 2013.
Whether you’re a business user creating a detailed quarterly report or a college student spending all night at the library writing a term paper, you want to focus on your work, not your remaining battery percentage.
With its extended battery, the 12.5-inch, 3.6-pound ThinkPad X240 lasts an amazing 20 hours and 28 minutes on a charge, long enough to pull an all-nighter or work on the entire flight from New York to Taipei. Add in a bright IPS touch screen, a powerful Haswell processor and a wide array of ports and you have a portable productivity powerhouse.
