36Kr noticed the posts on Apple's official forums and platforms such as Weibo, and many users reported that the iPhone X has reached the critical limit of 80%, which means users need to replace batteries for their devices. Because after reaching this critical value, although the iPhone will continue to work, Apple's performance management system will control the power consumption of the mobile phone, seriously affecting the performance of the device, and will also receive a reminder to replace the battery.
IPhone X was released in September, 20 17, where "X" stands for Roman numeral "10", which is a high-end model that Apple pays tribute to the 10th anniversary of the iPhone. Apple also equipped it with an organic light-emitting diode screen for the first time, with a battery capacity of 27 16 mAh. Apple official website said that the longest online time can reach 12 hours, which is 2 hours longer than the iPhone 7.
However, the battery life of iPhone X is still not satisfactory. According to a disassembly report disclosed by Fool's website, the battery capacity of iPhone X is even greater than that of iPhone 8 Plus, but its endurance is not as good as that of the latter. According to the report, this is mainly because the iPhone X has higher pixels and consumes more power. Meanwhile, in the OLED screen, each pixel emits light by itself. However, this model has not redesigned the user interface, and it is often displayed in dark color, which will be forced to render high-energy content frequently.

In addition, iPhone X has added the iPhone battery and performance guide of iOS 1 1.3 for the first time, and the "Battery Health" screen contains the maximum battery capacity and peak performance capacity information. As mentioned in the built-in battery guide, the device is expected to lose 20% battery capacity after 500 charging cycles.
The IPhone X has been released for two years. According to the frequency of charging once a day, most users will obviously charge more than 500 times. Users with serious battery aging (that is, the maximum battery capacity is less than 80%) will see that "this iPhone was unexpectedly shut down because the battery could not provide the necessary peak power, and the system applied power management to help prevent this from happening."
Apple once explained: "When the ordinary battery works under normal conditions, it can retain 80% of its original capacity in 500 complete charging cycles. The one-year warranty covers battery failure. If the warranty period is exceeded, Apple will provide battery replacement service, but there will be a charge. "
