No matter how stacked its specs are, a laptop is useless if it can’t hold a charge. Fortunately, there are plenty of notebooks that go the distance. Using our Laptop Mag Battery Test (continuous Web surfing over Wi-Fi), we’ve identified the 10 longest-lasting notebooks on the market. We’re talking anywhere from 9 hours to more than 20 hours of endurance, which should more than suffice for that cross-country fight, long day of meetings or multiple, back-to-back classes.
Lenovo’s X200 ThinkPad series is synonymous with portable productivity, and the X240 lets you get more done than ever without rushing to the nearest outlet. This lightweight laptop’s built-in battery provides a good 7 hours and 40 minutes of juice, which stretches to a whopping 20 hours and 28 minutes when you upgrade from its 3-cell to its 6-cell battery. This endurance is the most we’ve ever gotten from a laptop without a sheet battery attached to the bottom, and makes the X240 the perfect productivity companion.
One of our favorite business notebooks, the Lenovo ThinkPad T440s has the battery life to back up its strong fourth-generation Intel Core performance and vibrant display. This comfy laptop can be configured with a 3-cell battery that lasts an above-average 7 hours, but you should spend the extra $5 for the optional 6-cell battery that more than doubles that life to 14 hours and 36 minutes. The T440s also has an additional 3-cell internal battery, so you can swap out battery packs without your device going dead.
Not only does the Asus EeeBook X205TA offer more than 12 hours of battery life, but it’s also cheap. At $199, it gives Chromebooks a run for their money while offering Windows 8.1 and solid everyday computing performance. That’s all while being clad in a dark navy blue that shimmers almost purple. The thumping speakers are surprisingly good, too.
The latest MacBook Air keeps the same sleek design as its predecessor and adds a zippier Core i5 processor for $100 less. The best part? You still get awesome battery life. The 13-inch Air lasted a very long 12 hours and 20 minutes on the Laptop Mag battery test. Add in a comfy keyboard and touchpad and easy-to-use OS X Mavericks, and it’s easy to see why this $999 Air is our favorite ultraportable value.Apple MacBook Pro 13-inch with Retina display (2014)
The robust MacBook Pro 13-inch with Retina display grew even stronger for 2014, and Apple didn’t have to sacrifice battery life for added power. This stylish notebook lasted 10 hours and 44 minutes on our battery test–an hour longer than the 2013 version–providing plenty of juice for photo editing, video chatting with friends or spending late nights in the studio with GarageBand.
