“it sucks a huge amount of data in the background”
I’ve mentioned it before, but I’ll mention it again : This site seems to swallow megabytes of data in the background if you leave it open in Chrome (mobile).
I guess it might be my device (and the Huawei background data notifications are notorious for being very annoying) but the usage significantly ups my daily figures if I don’t actually close chrome, or, leave it on another page.
Noticeably less so with a P, like down from 5 megs an hour to a few KB.
