In 2016-2017, the top models of smartphones had a metal body. However, later they began to gradually abandon this. What does this have to do with?
At the end of 2016, the first Xiaomi Mi Mix was released, which had practically no frames. In 2017, the LG G6, Samsung Galaxy S8, and iPhone X appeared. After them, manufacturers began to abandon metal on the back panel.
The main reason why metal smartphones stopped being popular is – high thermal conductivity of the material. This turned out to be inappropriate as the power of chipsets developed. With high load, the smartphone case heated up faster, and in the cold – cooled down faster. It affected performance.
Yes, they still make phones with metal bodies. But they have either a special cooling system or a “cold” processor.
Flagship smartphones do not have metal covers due to the fact that they are not able to work with wireless charging. Also, the metal case requires the addition of plastic antennas for signal reception. This also affects the price of the device.
Another reason why many brands have abandoned metal in the case of smartphones, – impact on the total weight of the device. The density of pure aluminum is higher than the density of plastic, and now this moment is important due to the presence of massive blocks of cameras and batteries in many devices.
Now all-metal smartphones are produced by only two manufacturers. These are ZTE and Sharp.
