the 3nm process technology used in the A17 Bionic chip for the iPhone 15 Pro models is expected to significantly improve battery efficiency:
Key Points:
- The A17 Bionic chip built on TSMC's 3nm process is expected to consume about 35% less power compared to the 5nm chips used in previous iPhones.
- This increased power efficiency should translate to significantly longer battery life for the iPhone 15 Pro and Pro Max models.
- DXOMARK testing found the iPhone 15 Pro Max could last over 69 hours with moderate usage, ranking among the best devices tested.
- However, some early real-world testing has not shown dramatic battery life improvements compared to the iPhone 14 Pro Max, suggesting the real-world impact may be more modest.
- The non-Pro iPhone 15 models may not benefit as much, as they are expected to use the previous generation A16 Bionic chip rather than the new 3nm A17.
So in summary, the 3nm process of the A17 Bionic chip is expected to provide significant battery life improvements for the iPhone 15 Pro models, though the real-world impact may vary somewhat from the impressive efficiency gains touted by TSMC. The non-Pro iPhone 15 models may not see as dramatic of an improvement.
