Presenting their new products, smartphone manufacturers like to talk in great detail about innovative developments and innovations. At the same time, for some reason, the fact that the lion’s share of flagships is equipped with a long-outdated (22-year-old!) USB 2.0 protocol in the USB-C connector is always omitted. At the physical level, the USB-C connector with different protocols is unchanged: in USB 2.0, and in USB 3.2 Gen 1, and in the latest USB 3.2 Gen 2×2, we are talking about 24 pins. But they are used differently. We will not go into the jungle of their pinouts, but only indicate the speeds: if in the case of USB 2.0 the data transfer bus is limited to 480 Mbps, then in USB 3.2 Gen 2×2 we are talking about 20 Gbps – 40 (!) times faster.
Of course, the main reason for this situation is money: the use of fresh USB 3.2 Gen 2×2 or at least USB 3.2 Gen 1 (up to 5 Gb / s) increases the cost of smartphones by a couple of dollars, which, in terms of millions of copies of devices, turns into a tidy sum of lost profits. And the fact that expensive flagships that shoot 8K videos transmit them over ancient USB 2.0 for ages is of little concern to anyone. In addition, via USB 2.0 it is impossible to project a smartphone image onto a TV or monitor, as well as work in docking station mode (for example, Samsung DeX).
And this is not to mention backup, when the user needs to transfer 100-200 GB of photos and videos accumulated over a couple of years to a PC. A quick-detachable microSD card could simplify the situation, but meeting a flagship with a slot for it in 2022 is an impossible task. The funny thing is that this applies not only to Chinese devices, among which the recent Xiaomi 12S Ultra and OnePlus 10T are prominent representatives, but also to the current iPhone. Yes, yes, the top-end iPhone 13 Pro Max transmits data using a 22-year-old protocol. A list (of course, incomplete) of other devices, compiled by an enthusiast from Reddit, is attached below. In the comments, we suggest listing other flagships of 2022 on the USB 2.0 protocol.
