The new iPhone 12 of Apple family supports 5G networks, but sometimes 5G isn’t always as fast as the older 4G LTE network. In some places, like where I live in New Jersey, it’s slower than 4G LTE because of the way carriers are upgrading to 5G.
While the iPhone 12 can smartly switch between networks to save battery life, sometimes it doesn’t always use the fastest network. But your iPhone lets you easily jump back to the older, sometimes faster network. Network speeds matter when you’re trying to download big files, stream movies or download lots of music at once.
I’ll show you how to do that in your guide. I’ll also show you how to check your network speed. Then you can decide which network you want to be on. As 5G networks expand across the U.S., you may want to keep checking in to see if it gets faster in your area.
I’ll show you how to switch between 5G and 4G LTE. Then I’ll show you how to run a speed test on both networks so you can see which is faster. Keep in mind you’ll want to make sure Wi-Fi is off, since we want to test your wireless carrier network not your home Wi-Fi.
The SpeedTest app will test your upload and download speeds and give you a result at the end. It can vary wildly depending on where you are. Take note of your results. It might be something like 80mpbs down and 40Mbps up, for example.
