Looking at the basics, the iPhone 7 and 7 Plus bring at least a few new things to the table that we haven’t seen from Apple before, such as their first SoC with heterogeneous CPU cores. The iPhone 7 Plus brings a second camera with a full-frame equivalent focal length of 56mm, which isn’t really a unique idea but does represent a unique execution, as the G5’s second camera has an even shorter focal length. There’s some irony here as Corephotonics and Qualcomm have been demonstrating almost the same implementation as what we see in the iPhone 7 Plus, but Apple is the first to market here. IP67 means the iPhone is impervious to dust and is capable of sustaining 1 m of water depth for at least 30 minutes, but water damage is never covered by warranty so you shouldn’t push your luck here. Other changes here are more subtle such as the quad LED flash with PWM compensation, stereo speakers, and doubling the storage for all models relative to the 6s last year… More at ANANDTECH.
