5G is the latest feature that mobile networks are touting, but it’s not available everywhere. If you feel like your Android phone is wasting battery searching for a nonexistent 5G connection, you may be able to turn it off.
We say “may” be able to turn it off because this is a bit of a Wild West situation. There doesn’t seem to be any standardization for how to do this (if you are allowed to do it at all). Some carriers and manufacturers have either disabled the option or hidden it.
