Apple doubles the promised battery life of the iPhone 15 without software or hardware updates
22.02.24
Apple has updated battery life information for its latest iPhone models. The company now says iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max can retain 80% of their original charging capacity after 1,000 charge cycles, double the previous estimate.
Until this day, the company claimed that iPhone batteries retained 80% of their original full capacity after 500 charge cycles. However, after re-testing the long-term health of iPhone 15 batteries, Apple found that they could retain 80% capacity after at least 1,000 cycles.
Apple says testing included charging and discharging batteries 1,000 times under certain conditions and a battery of tests reflecting normal use. The company attributes the increased battery life without physical or software changes to ongoing improvements to battery components and iOS power management.
For older iPhone models released before 2023, the initial estimate of 80% capacity retention for 500 cycles remains valid. However, Apple said it is looking into whether to update ratings for older models.
Starting June 2025,smartphone and tablet manufacturers doing business in the EU will assign a rating (A to G) to devices indicating their energy efficiency, battery life, dust and water resistance and resistance to accidental falls.
