The new A17 Bionic chip in the iPhone 15 Pro Max is expected to significantly improve battery life compared to previous iPhone models:
- The A17 Bionic chip, built on a 3nm process, is expected to consume about 35% less power while providing better performance than the 5nm A16 chip[1][2].
- This increased efficiency should translate to longer battery life, with some reports suggesting the iPhone 15 Pro Max could last over 69 hours with moderate usage[4].
- However, initial real-world testing by one reviewer found no actual battery life improvements, with the iPhone 15 Pro Max still only lasting 10-12 hours before needing a charge, similar to the iPhone 14 Pro Max[3].
- The iPhone 15 Pro Max has a 4,441 mAh battery capacity, a minor 2-3% increase over the iPhone 14 Pro Max[4].
- In DXOMARK's battery testing, the iPhone 15 Pro Max scored very well, lasting over 69 hours with a moderate user profile and ranking among the best devices tested[4].
So in summary, while the A17 Bionic chip is expected to significantly improve battery efficiency, early reports suggest the real-world impact may be more modest. The iPhone 15 Pro Max still delivers excellent battery life, but may not be a major upgrade over the iPhone 14 Pro Max. More testing is needed to fully assess the battery life improvements of the new chip.
