Almost all manufacturers have long had standard usb-c, but these b*****s, even in mid-range models, do not intentionally output DP/HDMI to the usb-c (typical DP/HDMI Alt Mode), although they are built into the all SoC's.

With a conventional docking usb-c station, you could easily use any smartphone with an external monitor, keyboard and mouse, like a regular PC for surfing, and completely silent from PSU.

But this requires, as I wrote above, the use of a battery like in laptops - with a protective charge threshold of 5-10% minimum, which is not done intentionally, because the lack of a protective threshold is guaranteed to kill any battery with constant recharging.

I know of only one laptop manufacturer that has such a vile practice (according to the owners) with the absence of a protective self-discharge threshold - Huawei. Therefore, I do not recommend buying it laptops if you do not want to be left without a battery in a year while running 100% of the time from the PSU.

They're just doing it to make their port proprietary, standard USB C cables will not work.

I wrote a lot about the squalor of manufacturers of all smartphones for a long time, with rare exceptions - the power of modern SoCs is such that a smartphone is constantly connected to a power supply unit (with correctly set charging and self-discharge thresholds - for example, 100%->90%(self-discharge)->100%) through the dockstation with DP/HDMI and USB, can easily be used as a light (noiseless) laptop for several years. But this is deliberately not done in most models, although almost all SoCs support DP/HDMI outputs.

Because the main goal of all manufacturers is that you come to the store for a new model as soon as possible and provide them with uninterrupted profits year after year.
