The first authors of reviews on smartphones of the iPhone 12 line pointed to a decrease in battery life. This is stated in The Verge's review of iPhone 12 Pro devices.
According to editor-in-chief Nilay Patel, the battery life of the iPhone 12 Pro will vary dramatically between 4G and 5G networks. To test the autonomy of the smartphone, the journalist had to specially go to New York, where there is a zone of a stable network of the fifth generation. The results disappointed the author: “After about 2.5 hours of screen time, the smartphone still has 18 percent charge.”
Patel suggested that the difference in autonomy would also be noticeable using standard 5G and mmWave networks. This is due to the fact that the mmWave standard is more energy consuming. Problems with autonomy were also confirmed by the authors of Engadget, who advised to purchase the iPhone 12 Pro Max, rather than the younger models of the series, to achieve more battery life. In general, the authors of American publications called the decrease in autonomy one of the main disadvantages of new smartphones.
Also, the editor-in-chief of The Verge turned to Apple to clarify the situation with battery life. A commentary said the company expects the battery to last for an entire day of use. In conclusion, the journalist said that the iPhone 11 introduced in 2019 had better battery life than the current flagships.
Apple's next-generation smartphones were unveiled on October 13th. The series includes four devices with OLED screen, Apple A14 Bionic chip and 5G support. In Russia, pre-order for the iPhone 12 and 12 Pro opened on October 21, it will be possible to place an order for the iPhone 12 mini and 12 Pro Max from November 6.
