Smart TV features

How we test smart tv features
We test the internet-connected smart features of each TV, including how useful the menus are, how easy it is to use the app store and what the web browser is like to use.
Energy use
How we test energy use
Based on the power usage when being viewed and in standby and the presence and effectiveness of power-saving features such as a light sensor or radio screen blanking. Power usage can vary massively depending on the type of TV. OLED TVs tend to use less power than LED TVs since they don't have backlights.
Connections and tuners
How we test connections and tuners
A TV with plenty of connection ports allows you to hook up lots of different devices at once. Likewise, TVs with more digital TV tuners give you more options for watching subscription-free TV.
