the iPhone 15 Pro Max's USB-C port does not significantly improve its battery charging speed during intensive gaming sessions compared to the iPhone 14 Pro Max:
Battery Life During Gaming:- The search results indicate the iPhone 15 Pro Max has "poor autonomy during gaming" compared to other use cases, according to DXOMARK's battery tests. This suggests the battery drains faster during prolonged gaming.
- One reviewer noted the iPhone 15 Pro Max got "warm" after 30 minutes of playing a graphically-demanding game, indicating the device was working hard and consuming more power.
Charging Speeds:- While the iPhone 15 Pro Max has a USB-C port that supports the faster USB 3.0 standard, this does not translate to faster charging speeds during gaming.
- Both the iPhone 15 Pro Max and iPhone 14 Pro Max have similar maximum charging speeds of around 27W.
- In CNET's testing, the iPhone 15 Pro Max charged from 0-55% in 30 minutes, which is only slightly better than the iPhone 14 Pro Max.
So in summary, the switch to USB-C on the iPhone 15 Pro Max does not provide a significant boost to battery charging speeds during intensive gaming sessions. The battery still drains faster and the device can get warm under heavy gaming loads, similar to the iPhone 14 Pro Max. The USB-C port mainly improves data transfer speeds, but does not dramatically improve charging performance for gaming workloads.
