In the past, if the battery of the mobile phone was aging, we could directly remove the back cover manually and replace the battery by ourselves. However, the current mobile phones are all-in-one, and in most cases, you need to go to a professional repair shop to replace the battery. This change in mobile phones happened almost overnight. What is the reason for this change?
When it comes to the integrated design of mobile phones, the original use of this solution was Apple in the United States. Since the iPhone 4, Apple has been using the all-in-one design. Apple as the mobile phone industry boss at that time, naturally, his move has been followed by other mobile phone manufacturers. Samsung, Sony, Huawei, one by one mobile phone manufacturers have begun to use this design. These big guys will definitely not follow the trend blindly. The all-in-one design must have his advantages, so it will be widely used.
Still, when it comes to the internal space of the mobile phone, the higher the utilization rate of the internal space of the mobile phone, the mobile phone can often be thin and comfortable. The battery is made non-removable, which can greatly save the internal space of the phone, make room for more components, and improve the performance of the phone.
