AnandTech:

Overall, I think that if there’s any phone that is worth 650-750 USD at its base, it’s the iPhone 7 and 7 Plus. If you’re upgrading from the iPhone 6s Plus you probably won’t find a ton of differences, but it’s still a significant step up in display, camera, speaker quality, battery life, and system performance.

The iPhone might not excite like smartphones once did, but the amount of attention to detail and execution in the hardware is unparalleled and a cut above anything else in the industry.

This is the typical long, technical and very well done review from the folks at AnandTech. Settle in for a while to read more detail on the new phones than any other publication can manage.
