iPhone 12 '5G' indicator denotes best available connection
Apple has reportedly tweaked the network status bar indicator on iPhone 12 models to depict the best available speed and not necessarily the currently used connection.

That's according to a small tidbit concerning 5G support in a review of the Apple handset by The Verge. More specifically, the tweaked network indicators only apply to 5G-equipped Apple devices like the iPhone 12 and iPhone 12 Pro.
It appears that the icon behavior is a byproduct of the new "Smart Data mode" that Apple has added to iPhone 12, The Verge's Dieter Bohn notes. In a bid to save battery life, the mode drops the handset to LTE speeds unless iOS decides 5G connectivity is warranted.
"What's weird is that when the iPhone is limiting you to LTE speeds, it will still display the 5G icon in the status bar. It's now an indicator of the best speed available to you, not the actual type of connection that's actively in use," Bohn writes.
Similarly, it's not clear which situations will get 5G to kick in when Smart Data mode is enabled. Users can toggle the feature off in Settings, however. Bohn notes that he left the feature on and "honestly never really felt like [he] was being throttled."
As far as how 5G actually performed on the iPhone 12, the review notes that "it performs as well or better than 5G Android phones." Bohn adds that devices do heat up when 5G is in use, and battery life can take a hit if it's overused.
This isn't the first time that a status indicator has proven to be misleading on an iPhone. In 2019, AT&T displayed -- and continues to display -- a "5G E" indicator on devices that only support an upgraded version of 4G LTE.
It also isn't the first time that Apple has changed how the user-facing cell status indicators behave. Back in iOS 2010, Apple made changes that did away with an overly optimistic view of current connection strength.

Much of the time you aren't going to make use of full speed anyhow - it's so dependent on the speed of the server you're connecting to, traffic on the server, the traffic on the network in between, etc.
” devices do heat up when 5G is in use, and battery life can take a hit if it's overused. ”
So, if it doesn’t affect the user experience, saves battery life and keeps the phone from heating up when the iPhone drops down to LTE while you are reading email or doing some sort of low data operation, you’re gonna be mad that Apple is being a nanny?
I mean, one of the things that has kept Apple on the top of the heap for so long is that they care about the user experience. If you don’t care about the user experience and want to control every thing yourself just because, then you probably should be on an Android...
How is this any different than if I had a 5G signal but was only getting LTE speeds?
First, can you acknowledge that there might be a benefit to the user to have the phone drop down to LTE when low data usage is occurring? This was outlined in the article—lower battery drain and less generated heat.
The benefit of showing the highest speed signal available is that you can have the peace of mind to know that if you need it, it is there—while at the same time not incurring the negatives of 5G for no reason.
I suspect that Apple thought this through very carefully. Specifically that they are showing the highest option available. But, if it's not needed for the task (say Apple Music streaming) they utilize a more efficient method. But the user still gets all the speed needed for the process. It's like if it used only half of the 5G speed available, it would still be 5G.
It IS accurate. It just isn't indicating what you want it to indicate.
