iPhone 15 is the latest smartphone line from Apple, launched in September 2023. One of the highlights of this product line is the battery, which Apple claims has a higher lifespan than previous generations of iPhone. According to the updated support document on Apple's website, the iPhone 15 battery can retain 80% of its original capacity after 1000 full charge cycles, while this number is only 500 charge cycles for older iPhone models.
This means that the iPhone 15 battery can last more than half the time compared to previous iPhone models, before needing a new battery. This is good news for users, as the battery is an important factor affecting the user experience of the phone. With a more durable battery, users can use the iPhone 15 longer without worrying about running out of battery, especially when using high-energy features such as OLED screen, high-end camera, A16 Bionic chip or 5G connection.

Apple said they conducted tests on iPhone 15 models by charging and discharging the battery 1000 times under specific conditions, but did not reveal details about the testing process. Apple also said that they have continuously improved the battery components and energy management system of the iPhone, to optimize the performance and lifespan of the battery.
However, Apple also emphasized that the battery life of any iPhone model depends on the user's usage and charging habits. To check the battery capacity of the iPhone, users can open the Settings app and tap on Battery - Battery Health & Charging. On iPhone 15 models updated to the latest iOS 17.4 beta, this menu displays more information about the battery, such as the time the battery was manufactured and the number of charges.
The battery is one of the reasons for users to choose the iPhone 15, besides other factors such as design, screen, camera, chip or 5G support. With a more durable battery, the iPhone 15 promises to bring users a great and more secure experience when using their smartphone.
