Its showing 51% background process during the times of 12pm thru to around 1am, yes. I was referring to areas of time when device was not used or registering any usage from 1AM onwards.

Apple Music CSAM detection running in the background. 🤔😂

Okay, no worries. The graph was showing only so much, that is why I asked about the music app as being a potential issue.

Personally I don't have an overnight drain but when i have had this issue in the past, it was almost always a 3rd party app doing something. It is a pain in the arse but if this is a fairly new issue, I would start removing apps one by one and seeing if you can narrow it down or eliminate it completely.

Hopefully it becomes more natural for you, but again, it’s understandable if not. We all have our preferences and some Apple purists may not want to “mess with” the designers’ vision.

By the by, there’s one last setting, under Motion, I forgot to mention: Prefer Cross-Fade Transitions Pairs perfectly with the smooth, subtle, not-jarring-or-motion-sickness-inducing fade of Reduce Motion

Hey!

I don’t seem to see this motion option on my 12.

Now the music is running in the background. I haven’t used the device since last charge. But as you can see it’s active background now and showing in the graph. So to answer your original point of view. It would appear to be that bug for this example.

Battery life on my 13 PM really took a nosedive today and interestingly, the battery usage data for the past week completely reset overnight while it was plugged in. The only data present is from 6 AM today. Decided to do an IPSW shift+update to see if that fixes the issue 😉

I found kind of interesting bug today in TestFlight app on iOS 15.4.1, when typing a Feedback in TestFlight app the spacebar on the keyboard has weird blue hue color.

So far Ive found that only TestFlight app is affected, and it seems to only affect spacebar. 🤔

I reported it to Apple.

Will your device blow up, catch fire and disengrate after installing iOS 15.4.1, no I don't thin so. 😀

Thanks.
I was just pondering that with the reported issues with the update if it would be better to skip it.
I'm new to all of this and don't want to invite problems.
My 13 Pro seems to be working fine.
It's a tough enough learning curve as it is.

On my 13 Pro Max, iOS 15.4.1 seems to be working great. ProMotion seems to be a it more responsive and smooth, and battery life has been very good for me. I am seeing 0% battery drain in stand by.

Don’t be too concerned about what you see “reported” here. The vast majority of those reports are specific to those users and not to most of us. We have 4 devices - iPhone 13 Pro Max, iPhone 12, two 12.9 iPad Pros, one 2021 and one 2018. We’ve had virtually no issues with iOS 15 nor 15.4.1. I was on the betas with my iPad Pro but haven’t yet bothered with 15.5 because I’m not having any issues with 15.4.1 and haven’t read about any noticeable improvements in 15.5.

If you have a specific issue or question just start a new thread and people will help you.

15.4.1 fixed my battery drain issues however on both 15.4 and still 15.4.1 I have erratic cell connectivity. Usually when switching between Wi-Fi and 5g the 5g icon just disappears and I only see how many bars I have but have zero internet connection have to restart the phone to fix temporarily or turn my line off under cellular. Wondering if it’s a esim issue or what.

Cell issues have been spotty for some users for awhile now. It seems that Apple keeps updating the modem trying to tweak it to get better results. I believe the issue ultimately comes down to Apple's issues along with specific carriers. With that said, I am not saying to be a beta tester but if it means anything, 15.5 b1 did include another modem update.

Noticed a glitch or bug today. The face unlock unlocked but stayed on that screen with the open padlock for many many minutes until I had to manually swipe or lock the screen back with power button.
