Again, on a £200 phone, I don't think this is a big factor personally when 4G can handle plenty of capacity for a phone.
Its not the phones capacity I am on about but rather the network capability, if you have ever been to a popular event or large campsite for example where there are a couple of thousand people vying for that connection you get bugger all, the amount of devices contesting for mobile data is only going up, 5G will aim to reduce that congestion and the latency it brings, that's its biggest benefit more so than bandwidth, everything is after that mobile data now, not just peoples phones, I was driving around in a Polestar 2 the other day and the whole UI pretty much demands data and that's just a boggo car.
