Explain to me how this works, because this statement leaves me confused and I've seen similar statements on here before. The reason that I'm confused is that a 5 gigabyte movie is still 5 gigabytes whether downloaded over 4G or 5G so why would 5G use up data quicker? It's going to download it faster obviously but you're still only downloading 5 gigabytes.
What am I missing here?
It comes down to user habit, and it's why data consumption steadily increases generations. For example, if your 5GB movie takes 2mins to download over 4G LTE, and it takes 30s over 5G LTE, then you're more likely to download more 5GB movies since it's now quicker to access them. In other words, speed = convenience, and we as humans love when things are convenient.
Since things download quicker, people use more and more data. People will chew through more data with 5G LTE than with 4G LTE, just as they did with 4G LTE vs 3G.
