Chinese Weibo user Chef Alchemist purchased 210 smartphone circuit boards to find out how much gold can be extracted from them. As it turned out, the cost of consumables for the experiment significantly exceeds the benefits that can be obtained as a result.
To extract the gold from the circuit boards, Chef Alchemist performed several lengthy chemical reactions. At the exit, the enthusiast got only 0.41 grams of gold. The cost of such a “pea” of precious metal is about $30 on the market. At the same time, the purchase of boards alone cost Chef Alchemist $315.
Although extracting gold from chips is completely unprofitable in artisanal conditions, My Drivers notes that, on the scale of a well-established enterprise, recycling electronic waste can be very profitable. So, according to Chinese journalists, out of 1 million cards from mobile phones, you can get about 16 tons of copper, 350 kg of silver, 34 kg of gold and 15 kg of the more expensive metal palladium.
“This screen should be on all phones.” Reviews of Realme 10 Pro+ with ultra-thin bezel and 2160Hz PWM appear
One of the first reviews of the Realme 10 Pro + smartphone has appeared on the Web, and the device really deserves attention.
The journalists of the Gizmochina resource most of all praise the new screen, arguing that this should be in every smartphone. Recall, the new Realme is equipped with a curved OLED display with a very narrow frame. But it is also one of the first devices on the market that supports PWM at a frequency of 2160 Hz. Thanks to this, the use of a smartphone should not cause discomfort for people who are sensitive to flicker.
Our colleagues also note a low weight of 180 g, but Realme achieved it quite simply: both the case frame and the back cover are made of plastic.
The performance of the smartphone is very high, as it has a new Dimensity 1080 SoC, which is slightly faster than the Dimensity 920.
As for the rest, the novelty has a decent 108-megapixel camera, a lot of memory, excellent autonomy and good software (Android 13 with Realme UI 4 shell).
When iPhones with Apple charging will be banned: Europe sets a deadline for smartphones without USB Type-C
The final official deadline for when new phones sold in the European Union, including future iPhones, will be required to use USB Type-C for wired charging has become known: December 28, 2024.
The new EU USB-C law has just been officially published. We now know that the requirements will officially come into force in 20 days, and individual EU Member States will have a maximum of 24 months to implement them at the level of national legislation.
This is all more or less in line with previous policymakers’ predictions, but so far the exact date has remained uncertain given the number of stages each EU law must go through. When lawmakers reached initial agreement on the law in June, it was announced that it would apply from “autumn 2024,” but in October a press release said the rules would begin to apply “by the end of 2024.”
In addition to phones, the law also applies to devices such as tablets, digital cameras, headphones, and handheld game consoles. Laptops will eventually be covered as well, but not until April 2026.
Note that the new requirements only apply to devices that offer wired charging. That is, if Apple switches the iPhone to only a wireless charging method, then it will not be required to use USB-C instead of Lightning.
However, Apple has already confirmed that it is going to comply with the new rules. If Apple still decides to implement USB-C instead of Lightning, then without fail this should happen with the release of the new iPhones in 2025.
