You can look at the development history of the battery capacity of the iPhone 12 from the early iPhone to the present in the past ten years. The battery capacity of each generation of iPhone is accurate to ten digits. Especially in the past few years after entering the full screen, the battery capacity is directly accurate to single digits.
This is very strange, you can think about what Android is like? The unity is 2500 mA, 3000 mA, 4000 mA, 4500 mA, 4700 mA and other integers. There are not many accurate to ten digits, and it seems that there is no one accurate to single digits.
2 reasons：
The first is that Apple has put the battery capacity into a formula before making a mobile phone. The battery capacity of a new product should not depend on Apple's design, let alone how the surrounding manufacturers do it, but It depends on Apple's control of the quality of each product. For example, the battery life of each new generation of products is better than the previous generation, so if Apple wants to increase the battery life of the iPhone 13 by 10% compared to the iPhone 12, it will calculate accurately by combining processor performance power consumption, screen power consumption changes and other conditions. Figure out what the battery capacity of the iPhone 13 should be, and finally come up with a super accurate value.
The second reason is very common, that is, the battery capacity of Android mobile phones should also be accurate to single digits, but it looks cumbersome and unattractive. The difference in capacity is too troublesome, so everyone subtly uses this integer to express.
