There are several features and specs that people base their decision on when buying a laptop. There is the processor speed, graphics cards, screen size, and other upgrades. However, nothing is more important than battery life. Thanks to recent advances in battery technology and power efficiency, the minimum benchmark is at least ten hours of battery life on a full charge. The models below have battery life well more than the minimum.
Lenovo ThinkPad T470
The Lenovo ThinkPad T470 comes with an optional extended battery that takes the laptop to a staggering 17 hours and 25 minutes. The battery life is not the only thing great about the laptop. You get a best-in-class keyboard, fast SSD and durable chassis. The only drawbacks are a screen that lacks brightness and anaemic speakers.
Lenovo ThinkPad X270
The second best laptop regarding battery life is another ThinkPad. Again, you get a good keyboard, swappable battery and unlike the above, a better screen. However, you need to select the correct battery options to get the 13 hours and 51 minutes of battery life. The three cell batteries provide mediocre battery life.
Dell XPS 13
The Dell XPS 13 clocks in with approximately 13 hours and 49 minutes of battery life. The XPS 13 is one of the best allround laptops you can buy today and that includes great battery life. The XPS 13 has an amazing display, good Wi-Fi and is very light. The only drawback is odd placement on the webcam.
