What is the reason for the short battery life of iPhone 15/Plus?

After the iPhone 14/ Plus was released, many users complained that the battery health percentage of the iPhone 14/ Plus dropped rapidly after a few months of use.

Everyone expects the battery of iPhone 15/Plus to be improved. Unexpectedly, the latest iPhone 15/Plus series phones may also have the same problem: Yes It is reported that the iPhone 15 / Plus mobile phones use cheaper batteries, which only have about 600 charging cycles and age faster!

The reason why the newly released batteries of Apple’s new models are so not durable is mainly because Apple uses cheaper batteries for its mobile phones!

iPhone 15 / Plus phones do not support fast charging, and the phone battery loses less in a single charge, so Apple has cut costs in this regard and used cheaper batteries Units, similar to third-party components, only last an average of 600± charge cycles. Foreign media believe that Apple cuts costs on batteries because the company has established an extensive and reliable supply chain and retail network that can quickly replace batteries for users.

Why is the battery life of iPhone 14 and 15 series declining faster? X platform blogger RGcloudS explained the following:

iPhone 14 and 15 series phones use cheaper battery units, similar to third-party parts, which only have an average of 600± charges cycle, which is a high-density battery. The original iPhone 12 Pro Max has a battery capacity of 3687 milliamp hours (mAh), while the third-party iPhone 12 Pro Max has a battery capacity of 4350 milliamp hours (mAh). The battery capacity on the iPhone 13, 14, and 15 is the same or similar, but the iPhone 13’s battery is a high-density and high-quality battery unit.

# Speaking of lithium batteries, most phones, especially flagship models, use batteries with 800 charge cycles. Some phones from the BBK Group, such as the Find X, vivo X, realme GT 240W and OPPO, use more advanced self-healing battery units with 1,600 charge cycles. Batteries with 500-600 charge cycles are typically used in high-performance products such as power banks that support up to 300 watts of power delivery, vacuum cleaners, blenders, or handheld/portable devices that support a minimum of 100 W of power. 18650 and 21700 battery cells are commonly used.

What about larger devices/electric vehicles? They use batteries with 800 charge cycles. The best high-performance battery is found on the Vespa Elettrica electric motorcycle manufactured by LG Chem and has 1000 charge cycles. The problem is that the iPhone is not a high-performance (100W+) product, so having 600 charge cycles is unacceptable. In order to make significant upgrades without raising prices, Apple must cut costs, which is another factor in addition to falling NAND prices that explains why Apple has been able to keep prices stable.

Interestingly, recent iPhone batteries use recycled cobalt as the cathode material. Reusing recycled cobalt into the battery level actually costs the same or even more than It is more expensive to buy high-quality batteries with more than 800 charge cycles. Most of Apple's revenue comes from services. Therefore, if some parts in the product are easy to replace, it will cause more problems. As long as the display and other important components that affect daily use are not involved, the problem is not big.
