On a mobile device, web display pixels (logical pixels) are not the same as physical pixels.
An iPhone SE's logical width is 320px.
An iPhone 8 is 375px.
An iPhone 8 Plus is 414 px.
An iPad is 768px.
700 is more like a wap feature phone
WAP phones were closer to 180px. I know because I built local WAP news and weather sites for them. Squeezing color radar maps into 180px was... interesting.
