According to foreign media wccftech reports, a number of users complained that the iPhone 14 / Plus phone battery’s health percentage was in use for a few months after the rapid decline.

The latest iPhone 15 / Plus series of phones may also have the same problem, according to the media, which said that the iPhone 15 / Plus phones use cheaper batteries that have only about 600 charge cycles.
Apple’s reason for adopting a cheaper battery for the series of phones may be that the relevant models of phones do not support fast charging, the phone’s battery loss in a single charge is less, Apple cut costs in this regard, and ultimately used a battery with only 600 cycles.

Apple is cutting costs on batteries because the company has established an extensive and reliable supply chain and retail network that allows it to quickly replace batteries for users, the media said.
The foreign media also quoted a blogger on the X platform, RGcloudS, a long post, to explain
The relevant content is as follows:
Do you know why the battery life of iPhone 14 and 15 series drops faster?
It's because it uses cheaper battery cells, similar to third-party parts that average only 600± charge cycles.
Yes, it's a high-density battery. The original iPhone 12 Pro Max battery has a capacity of 3687 milliamp hours (mAh), while the third-party iPhone 12 Pro Max battery has a capacity of 4350 milliamp hours (mAh).
The battery capacity is the same or similar on the iPhone 13, 14, and 15, but the battery in the iPhone 13 is a high-density and high-quality cell.
When it comes to Li-ion batteries, most phones, especially flagship models, use batteries with 800 charge cycles. some of BBK Group's phones, such as the Find X, vivo X, realme GT 240W and OPPO, use more advanced self-healing battery cells with 1,600 charge cycles.
Batteries with 500-600 charge cycles are typically used in high-performance products such as mobile power supplies that support up to 300 watts of power transfer, vacuum cleaners, blenders or handheld/portable devices that support a minimum of 100 W. 18650 and 21700 cells are commonly used.
What about larger devices / electric vehicles? They use batteries with 800 charge cycles.
The best high performance battery exists in the Vespa Elettrica electric motorcycle made by LG Chem, which has 1000 charge cycles.
The problem is that the iPhone is not a high performance (100+ watts) product, so 600 charge cycles is unacceptable. In order to make significant upgrades without raising the price, Apple had to cut costs, which is another factor besides the drop in NAND prices that explains why Apple has been able to keep prices stable.
Interestingly, recent iPhone batteries use recycled cobalt as the cathode material, and repurposing recycled cobalt to battery grade actually costs the same or more, and is more expensive than buying a high-quality battery with 800+ charge cycles.
And most of Apple's revenue comes from services. So if certain parts of a product are easily replaceable, it will lead to more problems.
As long as it doesn't involve the display and other important parts that affect daily use, it's not a big problem.
I don't understand environmental protection,
