There's a good YouTube video I need to find again. But it compared the iPhone 8 Plus to the iPhone X, and actually the 8 Plus is the more powerful phone, with better battery life. Of course based on specs. He also pointed out how much in common both the 8 Plus and X have. These phones are damn near identical. Same A11 processor. Same 3GB RAM. Same harddrive. Same camera. Both are IP67 certified.
But the 8 Plus has the 1080p screen being more battery friendly, and less of a power hog. And the iPhone X has the front sensors always on looking at your face, and running in the background, some expect that to be a slight battery drain, as well as use up power.
So if you want the most powerful and fastest iPhone this Fall, and better battery life, it's the 8 Plus and not the X.
