I have never used an Android machine, and have been using an iPhone. So the following answer applies only to iPhone. 1. In the fall and winter and early spring, the mobile phone is easily cold, and it is easy to turn off automatically when the battery is low. Therefore, the original leather case of 428 has been used: a. The work material is sufficient and the use is exquisite; b. I bought the official silicone case once, but the cash back is too serious, and I have never bought a silicone case. c. Good protection and no heat dissipation problem in winter. 2. In the late spring and summer, the heat dissipation requirements for mobile phones are relatively high, and the pockets should not be too bloated. So buy the thinnest series like benks. Buy as thin as you can. This solves the problems of heat dissipation and portability. But protection is also reduced. 3. In the final analysis, everyone’s demands for mobile phone cases are different. Basically, if you want to change your personality frequently, you can start at 30 yuan-you can not only guarantee a certain quality, but also control the shell replacement cost. If you want to (relatively) high-quality workmanship and materials, then 428 328 official set. As for the price of one hundred or two hundred yuan, it is a bit high or low, and there is no gap between it and the 30 yuan, so I don’t think it is necessary.
