It’s not something I’m crazy about, but it has its uses. When I’m on my lunch break, my phone is sitting on the table so I can quickly glance at the time.
A bigger question is, why would I turn it off. I have the max size iPhone so the battery lasts more than my day. Besides that for my use, and I suspect for most peoples use the extra battery it uses is very minimal.
I think a lot of people don’t understand this always on display isn’t on when the phone is in your pocket. For me, that’s most of the day. If the phone is in my hand, that means the display is actually on so the always on part isn’t a factor. The only time my phone sits on a table for an extended period of time would be at night when it’s plugged in so it again battery life isn’t a factor.
What’s kind of weird is even though android had it first I don’t know anyone with an android phone that has it turned on. Maybe because of it’s very limited usefulness, but as I said, I don’t see a reason to turn it off. Maybe it’s off by default on android so they don’t see a reason to turn it on?
