Javascript/web performance on Android is universally bad but truly awful on the low end. A Moto G5 pulls ~14 on speedometer 2.0 which puts it in line with an iPhone 5/5s (5-6 year old devices). An iPhone XS scores around 123 in this benchmark for comparison, ~9 times faster.

I concur, having just purchased a Nokia 5 (for €105) and being surprised it felt so much slower than my iPhone SE. I guess it's a sign that speed/$ is flattening out. The good part about it is devices will stay competitive longer.
