Ranked in these QuestionsQuestion Ranking
Pro Performance is considerably better than on previous iPhone versions
The new 6-core, 64bit, A11 Bionic chip inside the iPhone 8 does not disappoint. Performance is smooth, as is expected from an iPhone, and, according to GeekBench, the iPhone 8 has 25% better performance on single core and 80% better performance on multi core compared to the iPhone 7.
Pro The camera is able to shoot very high quality pictures and videos
The iPhone 8 is equipped with a camera that is significantly improved from predecessors. Both the rear and front cameras take amazing pictures, especially at low light. The shutter speed and focus have also been improved from the previous iPhone.
The iPhone 8 can shoot 60fps, 4K video and 240fps, 1080p slow-mo which amounts to some serious video capturing capabilities.
Pro Can be comfortably used a full day on a single charge
The iPhone 8 lasts 14 hours on a single charge in airplane mode while continuously streaming offline video. Even though it does not tell the whole story on how it would fare during real-world use, tests show that you can use it comfortably for a full day on a single charge without worrying about battery life.
Pro Can be charged wirelessly
The iPhone 8 (with the X) is the first iPhone to implement wireless charging. What's more, Apple decided to implement the Qi standard for wireless charging which is shared by multiple manufacturers, making it easy to find a third-party non-expensive wireless charger .
Con Can't use wired headphones without a dongle
Since it doesn't have a headphone jack, you are forced to use bluetooth headphones or use a lightning-to-3.5mm jack adapter.
Con No significant improvements in the display
The screen is the same LCD screen used in previous iPhones and it's almost identical to the one found in the iPhone 7.
Con Buying a cover for it is highly advisable
Since Apple decided to ditch their design with an aluminium back and return to the glass back, having a cover for the 8 is almost a necessity since dropping it means you risk breaking both sides of the phone (back and screen) at once.
