The TL;DR answer is between two and three times as fast most places, but should you want a detailed breakdown of how popular phones on networks fare over 4G, Ookla’s published a pretty decent breakdown by country. Here’s the US cut and pasted from their side (top Android and iPhones covered.)
Of course your carrier, where you’re at, what time of day, weather conditions, will all affect your experience, but if you’re looking for a reason to upgrade and wondering how much better can a 5G capable phone be… here you have it.
You can find the full list of countries Ookla tested in by clicking here.
Oh yeah, side note – evidently Ookla aquired RootMetrics. Kind of a big deal.
