Recently, foreign technology media wccftech reported that the latest iPhone 15 series phones may face the problem of rapid decline in battery health. It is said that this series of mobile phones uses a lower cost battery, with only about 600 charging and discharging cycles.

Previously, multiple users had complained that the battery health of the iPhone 14 series had rapidly declined after a few months of use. According to a report from 9to5Mac in August this year, within less than a year of its launch, more and more users have shared screenshots of their deteriorating battery capacity on social media platforms. According to statistics from the media, the battery capacity degradation of these users ranges from 14% to 9%.

According to X platform (formerly Twitter) blogger RGcloudS, currently, most mobile phones use batteries with 800 charging cycles, while some phone brands even use more advanced batteries with up to 1600 cycles. However, the iPhone 15/Plus phone only uses 600 battery cycles.

According to Wccftech's analysis, Apple uses cheaper batteries to reduce costs. This is because Apple has established a wide and reliable supply chain and retail network, making battery replacement more convenient. However, establishing a large retail network is not cheap. During the global economic recession, Apple has had to maximize profits while maintaining product prices, which means reducing costs in certain areas.

RGcloudS stated, "The majority of Apple's revenue comes from services, so it is reasonable to assume that some easily replaceable parts in the product are prone to wear and tear

It is worth mentioning that RGcloudS states that the latest iPhone battery uses recycled cobalt as the positive electrode material. In fact, the actual cost of reusing recycled cobalt for battery level purposes may be higher, which is more expensive than purchasing high-quality batteries with over 800 charging cycles.

It is reported that in order to extend battery life, the iPhone 15 series has introduced the latest battery health management function. This feature allows users to set their daily charging limit to 80% to avoid fully charging the battery. To enable this feature, users can go to "Settings" - "Battery" - "Battery Health and Charging" - "Charging Optimization" on their phone. Users can choose from three options: optimized battery charging, 80% limit, and no optimization.

Apple stated that their battery design goal is to maintain up to 80% of its original capacity after 500 complete charging cycles. The definition of charging cycle refers to the complete depletion of the battery to zero and then the complete charging to 100%.

It is reported that in December 2017, Apple was exposed to secretly reducing the speed of its aging iPhone processor without the knowledge of users. On December 20th, Apple admitted that this practice was to avoid accidental shutdowns and extend the lifespan of its old iPhone.

Subsequently, Apple issued an apology statement and announced a reduction in the price of battery replacement for the iPhone 6 and its subsequent models, which were already under warranty. In addition, Apple has reached a settlement with the affected users and agreed to pay them a total of $500 million in compensation.

Recently, some users have claimed that the iPhone 15 series has an issue with phone overheating. Apple attributes this to certain applications and games, as well as vulnerabilities in the iPhone software itself. Apple stated that some settings of the new phone may cause the processor to work excessively, leading to overheating of the body.

Apple denies that the heating issue of the new phone is related to its hardware, and says it is about to release a software update that will not slow down the speed of the latest model of processor. Apple emphasizes that "the heat issue will not pose any safety or risk of injury to the phone, nor will it affect the long-term performance of the phone

According to Bloomberg, it is expected that sales of iPhone 15 may be affected next year as Apple users in the United States continue to use old phones without upgrading to the new iPhone 15. However, the survey shows that even if iPhone sales decline, Apple's revenue is still expected to increase, as consumers clearly prefer the high-end model ProMax, which starts at $1199.

Multiple investment banks have predicted that the shipment volume of iPhone 15 is expected to be between 70 million and 80 million units, a decrease from over 90 million units of iPhone 14 in the same period last year.
