Compact yet versatile enough to handle day-to-day applications, a laptop is the best tool for working, studying, browsing the Internet, watching movies, or playing games on the go. Though tablets and smartphones are smaller in size, most don’t want to trade off a laptop’s longer battery life, robust features, and the solid feeling of an actual keyboard.

While major brands like to highlight all the different and new technical features in their laptops – from the buzzwords about processors, types of storage, graphics capabilities, and screen resolution – Lenovo will cut to the chase in this buying guide and highlight the essential features that we think an everyday laptop should have.

1. Long battery life

Battery life is one of the most important considerations for many laptop shoppers. With an empty battery, your laptop is nothing but an expensive paper weight. On average, most laptops can be used for 4 to 6 hours on a single charge.

With Lenovo’s Power Bridge battery technology, certain Lenovo laptops can deliver up to 13.9 hours of use on a single charge. The external battery packs a charge of 7 hours while the internal Power Bridge battery adds another 6.9 hours of surfing, streaming, gaming, and more.

If you have a spare battery that is hot-swappable, this means you can use your laptop for more than 13.9 hours without ever turning it off.
