I am posting my first impressions of the new iPhone 8. This was an accidental upgrade because my iPhone 7 was "misplaced" during a recent motorcycle trip. I'm still hoping someone finds it.
First of all, I wasn't faced with the temptation of the iPhone X. An immediate replacement was necessary and the X wasn't available when I needed it. Luckily the iPhone 8 shares the same processor as the iPhone X and their speed is a noticeable improvement over the iPhone 7.
The iPhone 7 and the iPhone 8 look nearly identical. My old case fits and that was a surprise. There is a small difference in dimensions, so this won't be true of every case on the market.
There is a new type of glass on the 8, and it now has a glass back. This glass is supposed to be much stronger than before, though I did not test that claim. This makes the 8 a little bit heavier than the 7, but it is barely noticeable. The glass back enables the 8 to use wireless charging. I tried it, and it works, albeit a little slower.
Along with the glass, the display has been improved to include Apple's True Tone technology that adapts to the surrounding light and provides better color balance. This is subtle, but there is a pleasant difference, especially when compared to its predecessor. While the new display is not a game changer, it is nice to have.
I haven't used the camera enough to make a judgement yet. The optics on the 8 are the same as the 7, but according to published reports, the new Image Signal Processor improves the camera image and video capture.
The final item is battery life. My experience has been a longer lasting charge, but that is often true of a new phone with a new battery. I expect the battery life to be about the same as the 7. The new wired fast-charge feature is a welcome feature and is noticeable when you plug it in the car between stops.
All in all, I like the iPhone 8. If you are happy with your iPhone 7, I wouldn't say this is a "must have" upgrade. If you lose your old iPhone however, or just want the latest gear, the iPhone 8 brings a lot of improvements just beneath the hood.
