The number of reviews of iPhone 11 in Jingdong has exceeded 3.02 million, a new high. However, it is not strength that gets this result, but the price that keeps setting new low. Now that the iPhone 12 has passed 3C certification and will be released in September, sales of the iPhone 11 have declined. < / P > < p > the entire iPhone 12 series supports 5g, which should be the biggest surprise. Since cook took charge of apple, there have been a year of small updates and two years of big updates. Every time I squeeze toothpaste, I only give you a small surprise, and the big surprise will never be seen. However, the iPhone 12 is a historic mobile phone, and cook has to learn something about it. It’s another surprise that all four of them have OLED screens this year, but it’s a pity that the batteries are shrinking. < / P > < p > the purpose of using small batteries is to have a thinner body. At least the thickness should not exceed that of the iPhone 11 series. Otherwise, the weight will be increased and the use experience will be reduced. The iPhone 12 series returns to the tough style of the iPhone 5. If the weight and thickness increase, the experience will not be good. < / P > < p > the battery shrinkage is not without its disadvantages. This year, 2K resolution screen, 120Hz refresh rate and 5g are all big power consumers. It is impossible to expect such a small battery to surpass Android phones. The battery capacity of Xiaomi 10 supreme commemorative edition is as high as 4500mAh, 813mah more than that of 12 Pro max. the screens of the two mobile phones are almost the same size. Even if the power consumption of Apple A14 is lower, the battery life will not exceed that of Xiaomi 10 supreme commemorative version. 12 Pro Max has to bear the pain to give up the support of 120Hz refresh rate. < / P > < p > the size of the iPhone 12 Max is about the same as that of the iPhone 11, but the battery capacity is 335mah less, and the endurance is increased instead of decreasing. The low power consumption of A14 is the real credit. Compared with 7Nm, TSMC’s 5nm performance is improved by 15% and power consumption is reduced by 30%. In addition, apple A14 adopts a new architecture, and the performance is improved by 40 ~ 50%, while the power consumption is greatly reduced. Of course, this is only relatively speaking, now no one has seen the real machine, unable to verify. The high power consumption caused by 5g high network speed is difficult to solve even for apple. The iPhone 12 series has the same high pass snapdragon x55 5g baseband as Android phones. Android phones need large batteries, but the iPhone 12 series is an exception? Can the iPhone 12, with a battery capacity of only 2227 MAH, last a day in 5g mode? < / P > < p > the advantage of small batteries is that they can be charged quickly without upgrading, and only need 20W. In order to solve the problem of battery life, domestic mobile phones have used 120W fast charging head, which leads to the increase of cost. < / P > < p > in order to reduce the cost, the iPhone 12 gives up the charging head and earphone. The starting price is only 699 US dollars, equivalent to about 4800 yuan, and the Bank of China Version is more than 5000 yuan. The price estimation of 12 Max is similar to that of iPhone 11, that is, there is no price increase for the iPhone 12 series. < / P > < p > not surprisingly, the iPhone 12 series will also become a hit, selling better than the iPhone 11. There are online platforms such as Jingdong and PDD in China, so you can’t buy a lower price. 865 optimization is different? These mobile phones should teach you a lesson!
