A laptop's main value proposition is, of course, mobility and you just can't have it if you have to bring your power brick or a spare battery pack with you.

Fortunately, the laptops released in this year include several devices that are powered by battery technologies that can last an entire working day without charging.

Here are the top five most reliable laptops out of the current crop of devices this 2016. This should be distinguished from other "best lists" out there since the focus is on battery performance.

Dell Chromebook 13

It is not surprising that a Chromebook made it to this list. Chromebooks in general run a lightweight OS that consumes minimal power, so OEMs are not required to develop cutting-edge technologies to ensure that their Chromebooks last. That being said, the Dell Chromebook 13 is truly exceptional for trouncing its peers. You can expect it to soldier on for more than 13 hours of continuous usage. That is two hours more than what its closest competitor, the Acer Chromebook R13, could manage.

13-Inch Apple MacBook Air (2015)

Some claim that Apple's entry to this list is capable of 17-hour runtime. However, in continuous usage, it could only muster 14 hours. That period is still quite impressive especially when complemented by its sleek design.

Acer Aspire One Cloudbook

This 14-inch laptop will last you 14 hours and 43 minutes of continuous web browsing and media consumption. What is even more awesome is that the Acer Aspire One Cloudbook will only set you back around $230 for the 64 GB variant on Amazon. Aside from the robust battery, you will also get Windows 10, a full-sized keyboard and decent screen size for the price.

Lenovo Thinkpad T460

Lenovo's Thinkpads are the go-to computing device for those who want unbeatable keyboard experience. The T460, however, offers consumers more value due to its military-grade construction and its astounding battery performance. It is capable of 17 hours of runtime and more if the optional battery is factored in.

Lenovo ThinkPad X260

This other Thinkpad has beaten the ThinkPad T460 by a fraction. It will sustain your computing needs for an incredible 17 hours and 14 minutes. There is a 10-minute edge here over the performance of its sibling. To be fair, the X260 has a smaller screen size - 2.5 inches to the T460's 14-inch display - but smaller real estate does not necessarily mean it is a bad thing. There is greater mobility due to its lighter weight and you can easily tuck it inside your suitcase without accumulating added bulk and heft.

Just a tip for those who want to maximize their batteries, you can also try using apps that consume less power.
