5G devices typically use more battery power than their predecessors. In addition to the modem’s power needs, the more advanced components of newer phones can consume a lot of power – too. People can also use their devices for streaming video more often than before, as having a 5G connection can make it easier to watch programs and movies on the go.
Manufacturers can only increase the battery capacity of their phones to a certain extent, so it is essential to create new ways to make their devices more energy efficient. Samsung explains that the screen layout is “one of the most important components that affect a smartphone’s total energy consumption”. That is why equipping the S21 with a low-power OLED technology can “significantly impact smartphone usage time”.
