Yes probably a combo of those things which I hadn’t thought about, makes sense

iPhone 13 iPhone 13 - battery life thread [MEGA THREAD]

I have noticed that after my 13 Pro Max finishes charging and goes into standby, that it consumes very close to 0% battery while in standby. I was experimenting with turning on low power mode after charging finished, hence the yellow in the battery health graph. From 2:30am to 8:00am the battery looks like it drained pretty close to 0%. I noticed this last time I had charged overnight. In my case, I use a HomeKit smart plug and have a automation set up to start charging when my phone drops to 20% or start charging at 6:00am. Once charging has competed, the charger is turned off. I don't let the phone sit on the active charging.

Maybe it’s just us..So suprised that no ppl is talking about photo app is draining your battery
That initial percent, in your case charging stops at 85%, base on my own observation. Is equivalent to at least 5% worth of battery charge. IOS battery discharged algorithm is nonlinear and it’s “normal” for your iPhone to have 0% discharge during 6-8hrs of sleep on that single percent charge.
Example, I could on wifi stream with Netflix app for ~40mins+ or web browsing on safari for ~50mins+ at low brightness setting just on that 1st percent after taking my phone off charging. Afterwards, the discharged rate will go back to “normal”. Once I left my 12PM on standby after charging, goes to bed for 6-7hrs and still able to get 15-20mins sot before it drop 1% of charge.
Are you saying that after any meaningful recharge iOS waits up to 5% of actual battery loss before starting to drop the percentage indication? I might be observing something similar on this thread https://forums.macrumors.com/thread...t.2314721/page-20?post=30400504#post-30400504
I don't remember how my phone behaved before an unfortunate hard reset incident after which the battery indicator sometimes seems "stuck". But maybe it was like that even before of that
Adding to my previous post, it would be interesting for you to connect it to Coconut after some hours with the same percentage. My feeling is that you will be almost 4-5% under the reported percentage, and over the course of the day this difference will be smaller and smaller, around 1-2% like you already noticed (and me too, after some time from the last big recharge)
I can do that. It might give some insight. Next time I change my phone I will do that. Great idea.
In a way it’s what I have experienced and observed since my 1st iPhone, which is iPhone 4, and have stayed consistent till my current 12PM.
As opposed to android which have a observed linear battery discharge gauge. iOS, as least from my own understanding, is a nonlinear discharge gauge. The “last charged %” holds or is equivalent to more battery charge than it represents on screen, that single %.
If you charge your phone to 100% and it drops to 90% after some usage, the actual battery chemistry probably only holds a charge equivalent of ~85% at that stage. Obviously, it’s not an absolute value of charge remaining but an estimate.
That battery percentage “stuck” after rebooting is probably just a bug and not related to this.

I don’t use coconut battery but I presumed that coconut have access to raw readings of the battery state of charge and process it’s own estimate of battery charge remaining assuming it is linear. Which result in those discrepancies you mention in that thread.
I never realised this but you might be right. I think it's intentional to give a feeling that the charge holds more in the beginning. Coconut has access to raw data and I noticed that this 5% difference is there in the beginning, but then it subsides to 1-2% difference the more time it passes since the last charge. When rebooting the phone, iOS restarts with the "raw" percentage, so you can see an instant 1-5% drop depending on how soon you finished charging. I also suspect this all "stuck" bug might just be related to this 5% gap after charging. Thanks for the insight.
Unfortunately, my early experience has been my iPhone 13 Pro has much worse battery life than a 10 month old 11 Pro. Really wondering where the supposed improvement is.... Used 11 Pro for late 15 betas and then transferred data to 13 Pro. I don't turn off features like "hey siri" or light mode. 13 Pro has been seeing ~3-4 hrs of on-screen use by end of day, and 25-30% battery remaining. Use is mostly at home with good wifi and so-so Verizon LTE/5G.
Just catching up many posts over last 2 days by @coso @alexfoxy @Boardiesboi @aohus ... good info here.
Battery criminals seem to be location-related: Maps and Navigation *appear* to make a bigger hit. Sometimes when I've only looked up directions, and later see large amount of background use. Over the weekend I saw large numbers for Find My without apparent explanation. Also, Pocket Casts use and Safari see unusually high battery drain. Moderate use of Camera has not seemed a major drain.
Last night I ran battery down to shut off because I was down to 4% from a day of traveling and navigating. So far today, it *seems* better. Also, 2 hrs ago I turned off 5G (LTE) only as experiment (I know, two things change; not the best experiment set-up, ha!)
From last night:
15.0.1 (via IPSW)
iPhone 13 Pro
3.5h screen on; 9h screen off
4% remaining at 22:25
Looking at the OP posted graph it does not look like 8h 58m off-time from the dark blue bars.
The graph at the tail-end (5pm onwards) seems a little worrying. Usage isn’t much On-Screen but the drop is quite significant. What app(s) was in use during the last few hours?
The Screen On time and Screen Off time reported on the 24 hr chart may not be accurate. In my case, the graph is reporting 4 hr 16m. However, when I manually calculated each bar entry, I get a total of 3 hrs Screen On time.
In the case of @IsaacM, the graph reports 10 hr 40 m Screen On time. I did a cursory manual calculation of each of the bars and I got about 12 hrs 7 min.
So the question here is, which is correct, the SOT reported or each bar shown?

One thing that the 24 hr graph does not do is show the total SOT since the last time the phone was charged. In your case, when I did a manual cursory calculation of each bar, starting after the battery was off the charger, I estimated the Screen On time to be about 6 hrs 27 mins. So your battery life might not be as bad as you think it is.

Thanks… unfortunately 5pm rolled off my graph before it could check, but around 8-9pm it was Maps navigation, which I would expect a big hit. I did use both Maps & Waze without plugging in.
But look at this: Stocks 37%! Makes no sense. Maybe there is something broken in power tracking?

Anyone else have Find My Phone constantly pinging location? I feel like it’s been on for days. I have had the location indicator on constantly either solid or the outline but every single time I check it’s Find My Phone.
You’re right, it doesn’t make sense. You’ve used the Stocks app for a minute more than either Maps/Waze but I would still expect the latter apps to drain abit more for obvious reasons as they tend to “pull” data much more often, thus significant battery juice will be used. But then again we are dealing with a minute or two in terms of usage. So it’s hard to tell if Stocks is a problem. I mean say if you prolonged the usage for all three apps, eventually Maps and Waze would use more battery than Stocks.
I would try this if I were you: screenshot the graph daily and compare the graph on your “good” battery life days against the “bad” battery life days. It might tell you a thing or two. Sometimes there are other variables that are not easily ascertain like signal strength.
Thanks for the suggestions. Extra odd: I don’t recall using stocks last night at that time anyway. Today’s been best day yet for battery life though I’m not sure if my interventions or things balancing out.
The answer is neither are correct. Total screen on time is based on screen on time which is based on app activity time which are all flawed by their very nature.
I wish I would have seen this app sooner to safe you guys a lot of time.
Battery is a light weight system using shared resources to GUIDE the user to potential battery hogs. Its very generic and if nothing immediately sticks out at that time then it has nothing to offer you. You should not go diagnosing these numbers at precision levels because they will send you on a wild goose chase, they are not accurate in any sense of the meaning outside of a "quick overview". Again its a light weight system because precision tracking requires considerable resources thus measurable battery usage.
So here is mine manipulated for this thread....
Closer look...
Notice how my iPhones clock in the upper left is 11:11 then notice I have 1 hour of screen on time between 11pm-12am (same hour). Hour screen on time in 11 minutes....
This is because I can see seconds aren't tracked. Every app that is opened is "1m" at 1m 1s its "2m" so seconds are rounded up a minute PER APP. So merely by opening 60+ apps (1 app automatic adds 1 minute so 60+ app = 1 hour) you will give yourself 1h screen on for that hour, this will effect the total screen on for 24 hours.
Now that 60+ apps had no effect on battery so when using the app for diagnosing battery issues (looking for sudden drops in battery life) its not directing me there.
The app can be useful however we as enthusiast can easily over analyze it, those of us with battery issues can also see things that aren't there because we are trying so hard to see something.
I can type up a quick and dirty guide to using (or dismissing) the battery section if settings if anyone is interested.
