## The Battery Life of Apple’s iPhone 15 Surpasses Initial Expectations
Apple has recently declared a major improvement in the battery life of its newest iPhone 15 series. The technology leader announced that the latest iPhones could hold up to 80% of their initial charge after 1,000 cycles, which is double the company’s initial estimation. This adjustment does not require any hardware or software modifications and coincides well with the forthcoming EU regulations on energy ratings for smartphone battery durability.
Reevaluating Battery Performance
Earlier, Apple’s online support documents indicated that iPhone batteries could preserve 80% of their initial full charge after 500 cycles. However, upon reassessing the long-term battery performance of its 2023 smartphones, including iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max, the company discovered that these devices could maintain 80% capacity after at least 1,000 cycles.
Apple’s evaluation included charging and discharging the batteries 1,000 times under certain conditions and a series of tests reflecting typical usage. The company attributes this substantial improvement to ongoing advancements in its battery components and iOS power management.
Effects on Older iPhones
The original estimate of retaining 80% capacity after 500 charging cycles still applies to older iPhones (before 2023). However, Apple is currently studying whether these estimates need to be revised for earlier models.
Impending EU Regulations
Beginning from June 2025, smartphone and tablet manufacturers operating in the EU will be assigned an energy efficiency grade (A to G). This rating will also consider battery durability, protection against dust and water, and resistance to accidental drops. The battery durability element demands at least 800 charging cycles while maintaining at least 80% of their original capacity. This requirement may clarify why Apple started retesting the long-term health of its devices.
Suggestions for Optimum Battery Durability
For best battery durability, Apple recommends maintaining your phone in temperatures between 62 and 72 degrees Fahrenheit when feasible. It’s also advisable to avoid charging or leaving your phone in hot environments (95 degrees or hotter) and to minimize direct sunlight exposure. If you’re storing an old iPhone for an extended period, it’s best to leave it half-charged.
Modifications in iOS Settings
In another update, Apple will soon move one of your phone’s most critical battery metrics to a different section of iOS settings. Starting from iOS 17.4, currently in beta, the battery cycle count will shift from Settings > General > About to a more intuitive location under Battery Health (under Settings > Battery). Apple introduced the battery cycle count to its mobile software in iOS 17, which was released last fall.
Conclusion
Apple’s revelation about the enhanced battery life of the iPhone 15 is a notable advancement for users. The company’s dedication to constantly improving its battery components and power management systems shows its commitment to improving the user experience. With the impending EU regulations, this move sets a high benchmark for other smartphone manufacturers.
