Short and sweet, here's my impressions of my 2016 Jet Black iPhone 7+ versus my two day 2017 iPhone 8+. Display: iPhone 8+ has a touch better clarity. Contrast is better, and Black levels look more true and deeper. Saturation levels are basically the same with maybe a hint more pop on the 8+, but nothing major. True Tone is OFF, because I prefer cooler displays and True Tone leans warmer to my eyes with more of a "paper white" than "cool ice white." YMMV. Camera: iPhone 8+ captures more detail, has better saturation, produces less "sallow" skin tones. Front facing also has slightly better saturation. 4K 60fps looks great on my 4K TV (MacBook Pro to TV) and 1080p 240fps is quite dramatic. More deep diving on cameras later. It will take more time to really get technical, but it is better than the 7+ which I thought had a blah camera. Speakers: Phone 8+ blows the 7+ away. It's louder, clearer, has better sense of separation. "Hey Siri" is more reliable as well. It actually works from across the room on the first try more often. Size and Weight: 7+ cases fit the 8+. The 8+ slightly heavier due to the glass back. Nothing you'll notice in practical use. Bluetooth: My Beats Powerbeats 3 held a connection better on the iPhone 8+ while in the gym. Usually walks to the water fountain with the 7+ on the bench either results in the Beats disconnecting or turning off for a couple of seconds. Music played without interruption with the 8+ Speed and Responsiveness: iOS 11 runs about the same on both, with maybe a hint more responsiveness for the 8+. It's so minor that it should NOT factor into your upgrade decision in my opinion. The camera does launch more reliably with the 8+. The 7+ has hesitated on occasion. Nothing major that should cause you to lose the shot though. Looks and Feel: Subjective and personal opinion, but the iPhone 8+ feels and looks more like the first real successor to the iPhone 4. The way the glass meets the metal frame, the clean back panel, the subdued antennas lines, the symmetry and design...it all just comes across more like something Steve Jobs would be proud to hold up and call gorgeous. Bonus: Yes, wireless charging on the 8+ is awesome. I've used it more than wired so far. Though, it's slower than wired, so don't plan on topping off for 5 minutes and getting anything worthwhile. It's for sleeping and tasks like music while doing other stuff. Prognosis: The iPhone 8+ will be staying, and the 7+ is going back to AT&T. 8+ is a worthwhile upgrade for what I do. Again, YMMV. Final Thoughts: If you do opt for the 7+ DO NOT BUY JET BLACK. My 7+ has lived in a case from day one and the finish still looks like it was dogs chew toy. Jet Black has zero abrasion resistance, and will get marred by a cotton ball. Avoid like the plague. I have never had a phone look so bad before. Again, it was in the case the whole time! I will never buy a "Special edition" color again.
