There are several features and specifications on which people base their decision when buying a laptop. There is processor speed, graphics cards, screen size, and other updates. However, nothing is more important than the life of the battery. Due to recent advances in battery technology and energy efficiency, the minimum reference point is at least 10 hours of battery life with full charge. The models below have a battery life well above the minimum.
Lenovo ThinkPad T470
The Lenovo ThinkPad T470 comes with an optional long-life battery that can carry the laptop up to 17 hours and 25 minutes. Battery life is not the only good thing about the laptop.

The second best laptop with regards to battery life is another ThinkPad. Again, you get a good keyboard, an interchangeable battery and, unlike the previous one, a better screen. However, you must select the appropriate battery options to achieve 13 hours and 51 minutes of battery life. Three-cell batteries offer a poor life.

The Dell XPS 13 is synchronized with a battery life of approximately 13 hours and 49 minutes. The XPS 13 is one of the best laptops in the world and offers excellent battery life. The XPS 13 has an amazing screen, good Wi-Fi connection and is very light. The only drawback is the odd placement on the webcam.
