you don't even need to do that you go to 10 days on battery and click the day you're looking for. That gives you your true screen on active time.
I got 7 hours, 17 mins with AOD off and 6 hours, 17 with it on. Still lasts all day I'm sure if i ran it to 0% i would get over 7-8 hours even with AOD on.
Don't get how people can get 10 hours or more. Not sure how it's possible to be on a phone that long to be fair.
Just wanted to clarify that this might not be the case. The most accurate screen is the last 24 hours screenshot. The last 10 days with the full day bars can be extremely inaccurate.
A random case example to showcase this. I wake up at 5 am, unplug it at 100%. I use it all morning, but I have to go somewhere afterwards, so I charge it. I have to check things to plan for this trip, so I keep using it. I then unplug it and leave, using 30% until the evening, when I charge it again. Screen-on time compared to battery used will be massive, and wildly misleading, should I share the last 10 days page:
-It includes the 100-99% drop twice, which lasts 7 to 8 times longer than the rest of the percentage points
-It includes usage while charging, adding screen-on time whilst adding 0% to the battery used bar, not possible under not-charging circumstances
My observation: many, many, many people don’t know how to read the battery graph, demonstrated either by them including runtime prior to unplugging when reporting on the last 24 hours screenshot, or by sharing the last 10 days screenshot without context. Oftentimes, the number reported is astronomically high and impossible unless used extremely lightly, which their own account of their usage contradicts. I thank Apple for this. Screen-on time since last full charge is way too difficult, nearly impossible to implement, I assume. Probably requires a supercomputer to compute.
The current information makes any online claim without the last 24 hours screenshot proof completely unreliable. This thread is proof, every thread is proof. Somebody will, in every thread regarding battery life, ever since iOS 12, incorrectly report their own runtime as a lot better than what it is. I cannot know whether anyone who just states numbers without screenshots knows this, so I have to assume they don’t, which means I cannot trust the number that was shared, unfortunately.
As you know, iOS 10 and earlier had another inexplicable choice: usage, which lumped on and off-screen usage together. Which means people who listened to music all day had astronomically high results. The solution to this problem is way too obvious and way too simple. I’ll never understand Apple’s decision-making in this regard.
