Apple iPhone 5S (mobile 4G) comments

The advantage of operating system can't be overstated. The appearance design is very unique, brand effect and core technology.

The appearance is beautiful but not grand, the material is insufficient, the cost performance ratio is not high, the battery is not good, the heating is not good, and there are too many paid software.

Price performance ratio is mass market. I have used the iPhone 4. The back cover is beautiful. In addition to its own R&D and design strength, the success of Apple's operating system is closely related to the sameness of its rival Android and the immaturity of its Windows phone. Now mobile phones tend to compete with software, with personalization, fluency and personal customization. The habit of Chinese people is that under the influence of the current appearance, the advantages of Apple must be greatly constrained by the optimization and development of new operating systems or more user-friendly user experience in China.
