Apple said Tuesday that the battery life of its most **iPhone 15 series phones is twice as long as previously expected, reaching 1,000 charge-discharge cycles and still maintaining 80 percent of its original capacity. This change coincides with the implementation of new energy standards in the European Union, which imposes higher requirements on the life of mobile phone batteries.
According to Engadget, Apple has updated the battery life information of the iPhone 15 series phones in its ** support documentation. Previously, Apple claimed that the iPhone's battery still retains 80% of its original capacity after 500 charge-discharge cycles. But after retesting, Apple found that phones released in 2023, such as the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max, can still meet this standard after at least 1,000 charge-discharge cycles. Apple says this result is due to continuous improvements in its battery components and iOS power management.
Apple says its tests involve 1,000 charge-and-discharge of batteries under specific conditions, and a series of tests that reflect common uses. The company also said that this change does not require any new hardware or software updates and will not affect the user experience.
For iPhones released earlier than 2023, Apple still maintains its original estimate of 500 charge-discharge cycles, but says it is studying whether this estimate needs to be updated.
Apple's update to the iPhone 15 battery life comes as the European Union is about to implement new energy standards. Starting in June 2025, smartphones and tablets will be assigned a rating of A to G when sold in the EU, indicating their energy efficiency, battery life, dust and water resistance, and drop resistance, according to The Verge. Among them, the battery life score requires at least 800 charge-discharge cycles to still maintain 80% of the original capacity, which explains why Apple is starting to retest the long-term health of its devices.
To prolong battery life, Apple recommends that users keep their phones between 62 and 72 degrees Fahrenheit (16.) as much as possible7 to 222 degrees Celsius). In addition, users should avoid high temperatures (95 degrees Fahrenheit or 43.).3 degrees Celsius) should also be kept out of direct sunlight as much as possible. Also, if you want to store your old iPhone for a long time, it's best to keep it at about half.
In addition to updating the iPhone 15 battery life, Apple will also release iOS 17 in the upcoming release4. Adjust the position of the battery cycle count. Currently, this data is located in Settings > General About the unit, but in the new version, it will be moved to a more reasonable location, which is battery health (under Settings > Battery). Apple introduced battery cycle counting to its mobile software for the first time in iOS 17, which was launched last fall.
