That’s the whole point of the last 10 days. It’s basically how much you used your device and the percentage drop regardless of how many times you partially charge it during the day. It’s the aggregate of all the percentage drops during that 24 hr period.Is there actually a reason why Apple only shows the last 24 hours?
Sometimes I charge my phone during the day, so the 1 week chart isn't helpful and I can't tell how much screen on time I get with one charge.
why mine was only 89%100% every day 365 days a year, my 12 pro max had 99% battery health when I sold it.
It looks like you got about 2 hours, 15% battery used. That would be about 13 hrs on 100% battery usage. That's really good battery life.
I added up all the times from the bars. Of course, what I calculated was just an estimate. But it appears to be good battery life.You say that by measuring the bars in the 24h graph? It seems worse to me but I’ll analyze it better
I mean, is that better than showing the usage since last charge ?That’s the whole point of the last 10 days.

I think they changed that about 3 versions ago. This does provide more historical data compared to how they did before. Since last charge is for a more immediate info.I mean, is that better than showing the usage since last charge ?
That’s what we actually compare.
It gets tricky if it’s more than 24 hours since the last full charge.
Thought I saw that info in previous iOS version
The issue with the 10 day battery usage is that you can't tell when you had charged and the usage percentage is included if you had been using your phone while it was being charged. The only way to tell is to look at the 24 hour battery usage.I think they changed that about 3 versions ago. This does provide more historical data compared to how they did before.

I don't think it includes usage while connected to a charger. It clearly says "Battery usage by app" and you're not using battery when you're connected to a charger.The issue with the 10 day battery usage is that you can't tell when you had charged and the usage percentage is included if you had been using your phone while it was being charged.

I think that the battery usage always includes the time that the phone is being charged. I will use the battery usage that @cambookpro posted, I am including it below. Take a look at the area marked as charging. If you select one of the bars it will show you all the apps that were being used as "BATTERY USAGE BY APPS". I don't think iOS is distinguishing between battery or charging. That is what leads me to think the same about the 10 day battery usage.I don't think it includes usage while connected to a charger.

That’s why it only shows the 20% or so you use in that particular 24 hr period. But yes, in this specific case the older stats would give a better info.Issue is, if someone charged his phone like 2 days ago at 7pm(like me), it’s impossible to figure out the real screen on time. Because the 10 day data shows the usage before 7pm too.
Weird change tbh. They did that on Android too. The info is still there but they started hiding it more
Turns out it does include the charging time. I just made note of the Screen On time and used it with the charger connected. It did go up. Pretty dumb implementation I’d say.I think that the battery usage always includes the time that the phone is being charged.

I am not fond of the way Apple is tracking the battery usage. I think it is pretty much useless because it requires me to manually add up the individual bars on the 24 hour usage chart to figure out my battery life.Turns out it does include the charging time. I just made note of the Screen On time and used it with the charger connected. It did go up. Pretty dumb implementation I’d say.
Thanks for the clarification!
Ok, after another very bad day (50% battery for not even 3 hours of screen time) I reinstalled iOS15.2 from my iMac and set up the phone as new, let's see
Looks like you got about 7:30, 60% battery usage. Estimate to 100% battery usages, 12:30. That is really good battery life for a 13 Pro. The light blue on the bars (screen off) also uses up battery, it should be counted with the on screen (dark blue).I set up mine as new, hope it helps.
Here's my sot from last night, Happy New Year everyone \o/

How good is it to not have to worry about the battery anywhere near as prior generations?!iPhone 13 Pro Max
iOS 15.2
2:00, 9% battery usage, estimate to 100% usage, 22:13.
Since updating to iOS 15.2, my already great battery life has gotten what seems a lot better. For example, today I charged my phone as usual to 80%, that was at about 11am. 13 hours later, I had only used 9% battery (at 71%). Now granted today was a light use day with only 2 hrs usage. I find that really really impressive. I have Low Power Mode automatically turn on at 10pm and off at 8am, that is why you see the yellow areas.
There is still a ~4% variance from CoconutBattery, iOS still over reporting the percentage.
