How we test battery life

A laptop that manages more than eight hours in our test will normally score five stars, while one that lasts under three hours will normally get one star.

Screen performance

Overall

How we test screen performance

We look at how clear and bright the screen is, and perform scientific measurements to check colour accuracy. We also assess how wide the viewing angles are and whether reflections cause a problem.

Sound quality

Overall

Headphones

How we test sound quality

The quality of the sound that comes from the built-in speakers, and how well the sound card handles audio delivered to high-quality headphones through the headphone jack.

Practicality

Overall
Portability
Build quality
Quiet operation

How we test practicality

These scores let you know what a laptop will be like to take out and about. Lighter laptops made from premium materials do better here, as do those that manage their heat efficiently and quietly.
