What is an iPhone battery protection board? What is the encryption mechanism of the battery protection board of the iPhone?

The Apple battery protection board is an important part of the battery, which is responsible for monitoring the status of the battery and preventing the battery from overcharging, overdischarging, and short circuiting, thereby protecting the safety of the battery and the device. The life of the protection board is mainly affected by the number of battery cycles and the environment in which it is used.

The role of the battery protection board

The main functions of the battery protection board include:

Overcharge protection: When the battery voltage reaches the set value, the charging circuit will be automatically cut off to prevent the battery from overcharging.

Over-discharge protection: When the battery voltage drops to the set value, the discharge circuit will be automatically cut off to prevent the battery from being over-discharged.

Short circuit protection: When the battery is short-circuited, the circuit will be automatically cut off to prevent the battery from being damaged.

Factors that affect the life of the battery protection board

Number of battery cycles: The more times the battery is charged and discharged, the shorter the life of the protection board. Generally speaking, the health of a battery will decrease significantly after 500 charge-discharge cycles.

Environment of use: Extreme temperatures (too high or too low) can affect the performance and life of the battery and protection board. High temperatures can cause battery ageing to accelerate, while low temperatures may prevent batteries from charging properly.

Battery quality: The quality of the original battery is usually better than that of the third-party battery, because the protection plate of the original battery is more compatible with the battery cell, which can better protect the battery.

The encryption mechanism of Apple's battery protection board

The encryption mechanism of Apple's battery protection board mainly includes dynamic encryption and chip encryption protection

Starting from the iPhone 11 series, Apple has dynamically encrypted the battery protection board, which means that the data of the battery protection board is written in batches in advance and cannot be modified by individuals. This encryption mechanism ensures the accuracy and security of battery data. In addition, starting from the iPhone XS series, Apple has encrypted the battery chip, and when replacing an unofficial after-sales battery or a third-party battery, the phone will pop up to prompt that it is not genuine, and the third-party battery system does not show the health degree.

The main purpose of this encryption mechanism is to prevent the user from using unauthorised battery parts and to ensure the performance and security of the device. By encrypting the protective board and chip, Apple is able to ensure that only certified battery parts will work properly on the device, thus avoiding damage to the device or safety issues that could result from the use of substandard batteries.

Battery protection boards will be a key factor in measuring the quality of third-party batteries

iOS 18.1 has been released recently, and after the system update, iPhone X and above models can also view third-party battery health information. The protection board will be the key factor to measure the advantages and disadvantages of the third-party battery, the chip scheme is on the one hand, and the material process also tests the strength and intentions of the brand manufacturer.

Taking Guangxin Hongsheng as an example, the factory prefers the battery cells of large brand factories and strictly controls the quality of upstream battery cells. At the same time, Kuangshun Hongsheng brand battery protection board adopts domestic advanced chips and independent scheme design to ensure the reliability and safety of the production battery. With its two major brands of "GXHS" and "Xingyi", Guangxin Hongsheng has served the global accessories market and maintenance market for 11 years, accumulated a good reputation, and built a high-quality supply chain of Apple's full range of mobile phone batteries.
