11PM on iOS 17 RC, had to put it on charge as going out this evening and 33% isn’t going to be enough lol. Battery health is 81%.
For some reason I can’t seem to reply to your other comment so I’ll reply to this one instead.
It seems like it’s a little over 4 hours 100-33%. About 6 hours on a full charge. I don’t know how your usage was, but for an 11 Pro Max, it’s hours below what I’d expect on iOS 13, sadly. Maybe your usage is too heavy, I don’t know, but at first glance it doesn’t look great.
It’s hard to extrapolate with no information, my iPhone Xʀ on iOS 12 can get 16 hours of light Wi-Fi screen-on time, but with heavier LTE use it can get 11-12.
6 sounds too low regardless, the 11 Pro Max on iOS 13 should be better than my Xʀ, and I’m not getting 6 hours even with full LTE, higher brightness, and heavier usage.
High brightness and massive camera use on my Xʀ extrapolates to about 9-10 hours. That’s probably as low as it can go with my settings on iOS 12. Keep in mind that I’m an efficient user, though.
6 hours on iOS 17 for your 11 Pro Max would only be decent if usage was like that, very high brightness and massive camera use. Honestly, not looking great otherwise.
