A real stumbling block for many manufacturers, the autonomy of our favorite electronic devices is often lacking with an endurance that rarely exceeds the day of use. If on smartphones, fast charging compensates for these autonomy gaps, the laptop sector often leaves something to be desired on this point. Fortunately for the humble users that we are, Intel could have found a tailor-made solution to this thorny problem… and surprisingly it does not come from more powerful batteries, nor from processors less greedy in Watts.
This is precisely the interest of “Low Power Display Technology” that the founder of Santa Clara presented during his press conference at Computex. As its name suggests, this technology attacks the consumption of the screens of our laptops.
The great promise of Intel with this new technology is to allow our laptops to last around thirty hours before claiming a power outlet. An impressive figure that the brand obtained on an ordinary 13-inch laptop, however equipped with a (very) energy-efficient panel, developed in partnership with Sharp and Innolux. According to Intel, the device would last, thanks to its screen, no less than 28 hours on battery.
Figures that unfortunately must be taken with hindsight
Main specificity of the panel developed by Sharp and Innolux, its consumption is reduced to just 1 watt. That's half the size of a typical laptop screen. Through this great advance, Intel announces that – depending on the models and contexts of use – laptops that will be equipped with it will be able to count on 4 to 8 hours of endurance more. On a Dell XPS 13, the company indicates for example that the autonomy has increased from 20 to 25 hours. It's a lot, but there are clearly a few caveats here.
In order to achieve such autonomy, a certain number of concessions have to be made. Intel thus admits that it is necessary to activate several energy-saving systems, to favor a headset with integrated speakers, and to lower the brightness to practically the minimum. Finally, note that this famous “Low Power Display Technology” only works with Intel graphics circuits.
PCs with GPU chips from Nvidia and AMD will therefore not be able to take advantage of this.
