I’ve almost never had an issue. Like ever, unless I forget to set my phone on a charger when I went to bed. And even then, it would just be in the single digits by the end of the second night.
I think I’ve had my phone die on me twice since I’ve had it (Pixel 6 Pro).
Great. I don’t need that. That’s not even close to a selling point.
I guess if I needed to hike without a power source for a week, it would be.
