Apple has pushed iOS 174 system, in the new system, Apple has improved the battery health function, which can provide additional information about the production date, first use date and cycle number of batteries in addition to the battery health, so that users can have a clearer understanding of the current status of the battery.
The evolution of the battery health function only provides more battery information, and does not optimize the battery in any way, which does not help the battery life of the mobile phone, at most it can remind the user when it is time to replace the new battery.
Previously, Apple's battery could only provide about 500 cycles, and this life span could not last for 2 years at all, and even for some heavy users, the time of 1 year would be exceeded, resulting in a serious attenuation of the battery life of the mobile phone.
In the iPhone 15 series, Apple has improved battery life, maintaining 80% battery health after 1,000 charge-discharge cycles, and its expected battery life cycle will significantly exceed user expectations. Many users also said that the battery degradation of Apple's iPhone 15 series was significantly higher than expected.
For iPhone 15 series users, the battery health is less than 80%, or the cycle count reaches 1000 times, and the battery needs to be replaced.
In comparison, the battery life of Android phones is longer, and high-end models generally have more than 1,600 charging and discharging cycles, and the frequency of one charge per day can provide more than 4 years of normal use.
