Test iPhone 8 battery life and charging speed

The poor phone battery life of Apple’s iPhone is always criticized by users. After the iPhone 8 was released, its battery capacity was very unsatisfactory for users. After all, the iPhone 8’s 1821mAh battery was 7% less than the iPhone 7’s 1960mAh battery. However, the A11 processor of the iPhone 8 is built on a 10nm process, and its efficiency is quite good, so the battery life is not worse than the iPhone 7.

The media gave the iPhone 8’s battery test data, its comprehensive battery life is 8 hours and 37 minutes, 51 minutes more than the iPhone 7’s 7 hours and 46 minutes, and much better than many Android flagship phones. However, the media also said that this is only theoretical test data. In actual use, the iPhone 8 still needs to be recharged every day.

Charging speed is an important standard in mobile phone life. Apple’s three iPhones (iPhone 8, iPhone 8 plus, iPhone X) are equipped with fast charging function, but Apple does not provide fast charging on the standard charger. If you use the standard charger, then the iPhone 8’s charging performance can only be described as bad. It takes 148 minutes to fill this 1821mAh low-capacity battery, which is too slow.
