iOS 12 battery monitor lacking usage/standby values since last charge

It’s mostly background usage when the screen is off yet it doesn’t seem to be totally accurate. I ran 15 miles yesterday while listening to Spotify. I also listened to some podcasts with the screen off and the background times added up not do not equal the screen off time. I’m confused as well....

Exactly, I noticed the data is incorrect, it always seems less than the actual background usage.[/QUOTE]
Exactly. It is less and even the screen on usage time seems off. Every time you open and app it adds 1 minute of usage no matter how long you use the app. So if you open 40 apps and close them right away it shows 40 minutes of screen on usage right away! It’s screwed up.
[doublepost=1537282728][/doublepost]I’m also having a problem where the battery usage won’t show up sometimes. The spinning wheel just keeps going and going forever. If I close settings and reopen it it eventually comes back. Clearly some bugs happening.

I want to see the simple battery stats as before, this is now a confusing mess that doesn’t give me total usage since last charge or standby.

And it’s gives the feeling that the battery life is very Bad. And it really is.

Hi everyone,
is it just me, or is the new iOS 12 battery screen lacking information that were there until iOS 11?

Specifically, until now it was possible to see how many hours the iPhone was actually used and in standby since it was last charged. The new battery screen only shows usage (screen on and screen off) during the last 24 hours or 7 days, but not since the last charge.

Am I just not looking in the right place, or has this information actually been removed?

It's a little bit late, but since this post is coming on top of Google, so I think it's good idea to put this suggestion here. You can still see how long your phone is running since last 100% charge, it's just that you can't see the stand by time and usage time like previously we were able to see (of-course you'll require to do a little bit calculations as others suggested).

In attached image with this post, you can see that it shows Last Charge Level 100% and then it shows the time Sat 7:25 AM on which it was done.

Disclaimer: I am NOT really sure but it seems to me that my findings are correct.

I agree at first it's weird this has gone, but I'm starting to think the vast majority of the time it's not needed now we have the extra data.

Just look at the 10 day view and you'll see how much battery you used every day for the last 10 days. You can compare this to activity in the chart below, to see how it varies with activity, and select a day to see the app breakdown of the day.

Checking time since last charge only gives you a single look at battery use. This new view gives you much more.

Please give me use-cases for "time since last charged" that you don't think can be fulfilled by the new views. Not saying there aren't any - just interested to hear what they are. I'm wondering if perhaps some of them are dependent on a way of thinking which isn't necessary any more?

Total battery time usage since last full charge enables you to see how many hour your iPhone is getting on a full charge.

Im also not understanding this new charts, you can see and calculate time from last charge, and you can see total screen time on the screen off indicates background usage, so (hours since last 100%)- screen off + screen on ?

So if screen on is 5hrs and screen off is 1 hr and time since last chargen is 10 hours, stand by is 4 hours ? 10-(5+1)?

Standby is 10 hours--it's simply the time since last charge when the device was unplugged. Screen on and off times are from last 24 hours or last number of days, depending on the tab you select.

How can it be 10 hours? Stanby is not active at all isnt it ? Meaning no background activity or screen on ?

Standby, at least in the sense that Apple has used it in iOS until iOS 12, has simply been time since last charge.

And, more precisely, how different usage patters throughout the day impact battery life.

Isn't that exactly what the new battery stats do? Instead of just showing you how much time has passed since the last charge (which varies depending on signal strength, apps used etc), it shows your usage pattern throughout an entire day (or week) and how battery is affected. Ie, it does exactly what you said in your post.

The old battery stats were useful for determining how much usage was achieved per charge. I'm not saying this isn't useful - I miss this feature because now it's much harder to tell how long your battery actually lasts unless you write down the numbers from the graph and do the math yourself. But for most people I can see the graphs being much more useful - again, in your case it literally does the exact thing you want it to do - it shows how usage patterns affect battery independent of charge cycles which is something the old stats didn't do.

I think that the 'time since last full charge' allowed me to know - at a moment's glance - how much should I expect of my battery depending on usage patterns.
For example: My iPhone 6s on iOS 9. I know that if I use it with Wi-Fi, indoors (low brightness), I can expect 8-9 hours. If I use it with LTE, but with great signal, and outdoors brightness, but not max (I don't know, 50 to 75%) I'll get around 7. In the same conditions but with awful signal, it's 6 or slightly lower.
I don't use many apps. I know what's the energy impact of each app I use.
What help is it to know that last week I used my phone for 25 hours and that the app that consumed the most is, say, Safari, with 54%? It's absolutely useless. I have no idea whether Safari is a heavy app or not.
The hour-by-hour breakdown, OTOH, is more helpful, but requires more time to check.
Also, I don't want stats independent of a cycle. A cycle is all that matters (to me). As a compromise, Apple could have added those stats as a 'time since last full charge' breakdown.
Also: I often leave my phone in standby untouched for hours. The 24-hour breakdown is useless in that case. Say, I wake up at 7am, check it at 8am, and start using it for something at 6pm, and use my iPad in the meantime. Then, when I plug it in at night, the stat is pointless.

They intentionally removed it.

Apple doesn’t want the user worrying too much about battery.

But instead provided even more granular battery statistics and details?

Pretty sure that was not the case, if usage was high and standby was low, meant phone didnt go in to standby(sleep) and something was working in background, thats how poor battery performance was troubleshooting was done, standby + usage was full battery cycle on battery. How accurate it was is another question. I dont see standby time anymore, but now we do see when it was at charger last time and can calculate hours on battery.....

What I described is how it works/appears in iOS prior to iOS 12. It's not the typical way that many of us would interpret "standby", but that is how it was being presented there.

In terms of the troubleshooting of the type you mention, it was usually in the form of usage time being the same as standby time or close to it (but never being greater than it). Certainly plenty of threads (and articles) out there about it.

You right.
