With iOS 17.4, Apple now allows you to check the battery cycle of the iPhone 15 as a built-in feature. Given the concerns of many iPhone users about their device's battery life, Apple has recently rolled out another key feature specifically for iPhone 15 users.

According to Apple, the battery life of the iPhone 15 lasts longer than all previous models. The company states that the iPhone 15 can complete at least 1,000 full cycles, retaining up to 80% of its battery life, compared to 500 cycles in previous versions. While the company hasn’t clarified how this is achieved, it might relate to a new setting that restricts charging the iPhone 15 to just 80%.
Whether or not to use the optimized battery settings on the iPhone depends on your preference, but there are pros and cons to consider. For users looking to save battery life on their iPhone, understanding the battery cycle of the iPhone 15 is crucial.
The iPhone 15 battery cycle helps you better understand the health of your device's battery.
In recent years, Apple has provided suggestions for either replacing your phone's battery or considering upgrading to a newer iPhone model to ensure battery longevity. Now, with the iPhone 15, you can track how many cycles your device has gone through. The phone can last up to 1,000 cycles before reaching 80% battery capacity. Here's how to check the battery cycle on your iPhone:
- Once your iPhone 15 has been updated to iOS 17.4, go to the general settings
- Search for the battery section and tap on battery health

After completing these steps, you'll be able to see the manufacturing date of your iPhone 15's battery when you first used it and the number of battery cycles. Apple states that a cycle refers to the number of times the iPhone has fully used its battery's capacity. When it drops below 80%, Apple will switch it to maintenance mode, and at that point, you should replace the battery to ensure optimal performance.
How much battery capacity does the iPhone 15 have, and how is its battery life?
Apple has not officially disclosed the battery capacity for their iPhone models, but based on tests, we can estimate the battery capacity of the iPhone 15 series. The standard iPhone 15 features a 3349mAh battery, while the iPhone 15 Plus, 15 Pro, and 15 Pro Max are equipped with batteries of 4383mAh, 3274mAh, and 4422mAh, respectively.

According to Apple's announcements and real-world testing, the battery life of the iPhone 15 is sufficient to last an entire day. It offers up to 80 hours of music playback and 20 hours of video watching. Battery performance on the iPhone 15 depends not only on the efficient chipset and battery size but also on how intensively you use the device. When it comes to charging speed, the iPhone 15 supports fast charging with a 20W power adapter, allowing you to charge 50% of the battery in 30 minutes. This means that you’ll need approximately an hour to fully charge the phone.
