The first generation is lighter and quieter, while the second generation has more functions (with glare light, LED temperature display) and stronger hardware performance.
In fact, these two models are both semiconductor refrigeration and heat dissipation. The difference in heat dissipation effect is not particularly big, and you get what you pay for. After all, the 2nd generation pro has a temperature display. Although it will appear when the temperature drops a little bit, There is a sense of peace of mind and satisfaction, but who keeps staring at the temperature screen when they are having fun? As long as you are happy to use it and it can achieve the purpose of heat dissipation.
One point that needs to be complained about the 1st generation: Xiaomi Ice Cooling Back Clip does not wear a charging cable, but if you have an extra USB-Type C charging cable, you can ignore this problem.
The basic function of the cooling back clip is to dissipate heat. Other irrelevant functions are basically not extra burdens required by the user. Displaying the temperature is not necessary. The temperature of the previous generation cooling back clip can be reduced to 10-20°C. This The temperature already meets the basic cooling requirements, and there is no point in upgrading.
If the temperature of the mobile phone is too low, it is not the optimal operating temperature, and may cause other unpredictable risks. This release can be considered a meaningless new hardware product. Personally, I think that apart from the so-called sense of technology and coolness, It’s cool, has no practical value, and the extra cost is a pain point for you as a Xiaomi user.
This is a design plan for harvesting leeks. The cooling back clip only needs to maintain a good level of heat dissipation, improve grip, reduce weight, increase battery life and reduce power consumption. This is the key to real technological improvement. Just needed.
