Just checked again and the only thing I see is Siri randomly showing up three times last night. I deactivated Siri completely now. Let’s see what it shows tomorrow morning

Similar to mine when not in airplane mode. Lost 8% a night with only Wifi on and no notification nothing and 27% one night with only LTE on and about 5 notifications.
Maybe we should tell Apple about that, couldn't hurt and only takes a minute or two.

My iPhone 12 Pro max went from 94% to 88% overnight in the same time frame (7:30 hours). The iPhone 12 has a smaller battery percentage wise the difference translate into a smaller variation in mAh / energy consumption.
I use night mode. Maybe that reduced overnight mode.
it is the same for me with 12 mini, but it seems i have bad reception inside, only 2 bars
That's caught me out too. When I got my first Apple Watch a couple of months ago I was disappointed how it affected my iPhone battery life until I realised that I'd installed the NHS England tracking app at about the same time and that was what was responsible for my reduced battery life.
It would be nice if Apple could add turning exposure notifications on/off as a Shortcuts (personal automation) action so that you could set up leaving/returning-to home location-based shortcuts to turn it on/off. As second best I have leaving/returning-to home personal automations set up that vibrate my phone then pop up an alert that if I hit OK automatically launches the NHS England app so that I am on the page with the toggle to immediately turn it on or off as appropriate. Sadly those shortcuts that were working perfectly on my 11 Pro Max aren't firing at all now on my 12 Pro Max but that's a work in progress.
In answer to the OP's question I lose about 2-3% overnight but I do have timed personal automation shortcuts set up to switch my phone into airplane mode at 11:00pm and out of airplane mode at 9:00am every day. (Yes, I recently discovered shortcuts! It had been infuriating me for years, ever since my first iPhone 4, that there was no way to automatically put an iPhone in and out of airplane mode overnight in case I forgot to put it on a charger so I was really excited when I discovered a few months ago that I could now do this with Shortcuts. A bit late to the party I know but better late than never.)
My 12 mini had been losing around 10% overnight on average. Last night it lost 40%! And it has been draining faster than normal while idling today, even after a restart. The battery screen shows no apps in use overnight. The only thing that changed was that I installed the 14.2.1 update yesterday.
Is anyone else seeing an uptick in battery drain? The 14.2.1 update did include lock screen changes specifically for the mini...

EXACTLY the same!
Upgrading to 14.2.1 fix the touch issuees but overnight battery with NO Apps running is like 40+%!!
I may be having the same issue. I wake up and it’s 95 percent. S by 7 20%!! Not good where my max is 70% at 7pm.
Ok I went to bed with 80% and woke up to 67% again ... nothing shown as running. How do we tell Apple
I have battery drain problems on my mini as well. I only logged in to iCloud and didn’t download any apps. My sim is still in my 7, because my mini has a display problem and I’m still debating on sending it back again (it’s my second mini with a green and washed out screen). Yesterday it lost 12% battery at night. And last night it lost 17% battery at night, while it’s absolutely doing nothing in my drawer.
My 7 with all apps installed and the SIM card installed loses 0% every night. (I disable WiFi at night)
edit: I don’t use iCloud for my photos. Only use it for keychain and contacts. So it’s not busy with photo syncing etc.

I've had this issue with idle/standby drain since I got my phone on october 29th. It's draining on average 10-15% every night, and also has excessive drain while on standby during the day. I've had peaks of around 27% nightly drain, but also 3 nights with a drain under 5%. Yesterday it seems to have had a normal daily drain while idle, and this night it only lost 3% which I would consider normal and acceptable. Now as I said I've had a couple of these low-drain nights before, so I'm guessing it will go back to drain >10% tonight, but we'll se.
What version of iOS are you currently running where you experienced low battery loss overnight?
I’ve had iOS 14.1, 14.2 and 14.2.1. The battery drain seems to be the same under all of them, it differs every night but on average 10-15%. I think I’ve had low drain periods on all versions, but really high drain nights as well.
I put mine in flight mode with WiFi and Bluetooth disabled last night and for the first time it didn’t drain over night. Tonight I will try it with battery save mode on instead out of curiosity
I discovered that my VPN (ExpressVPN) app was draining battery rather high, so I turned it off just to check to make sure, and sure enough, I now can use my phone for two whole days, whereas before with the VPN, I was only getting about one and half days. Battery drain during sleep.

Is there any recourse for those of us who have no apps running, background app refresh off, on WiFi, etc and still seeing 10%+ drain overnight? I don’t want to be stuck with a defective phone on my lease with sprint. I have about a month left of limited AppleCare coverage. I’ve reached out to Apple support twice and they said my battery is healthy. I completely disagree, a brand new battery should hold charge better with no activity.
it’s harder to track during the day, but I also can’t make it through a whole day without charging my phone. I do use apps/text, but my XS max would have plenty of juice left after similar usage at the end of the day.

Yes.. I only logged in to iCloud. And my 12 mini battery drains more than 10% at night when idle. I’m not using iCloud for photos so it’s not syncing or something.
I Didn’t download any apps. And my SIM card is not installed. WiFi is disabled and blue tooth too.
I don’t use the mini because I’m still deciding on sending it back. Because my screen has a green tint/all colours are inaccurate. (Not the green glowing/flickering issue but another issue). I’m waiting for a software fix first. But decided to not use the phone so that I can send it back when there’s no fix coming soon.
I do think it has to do with iOS 14 maybe? Because this mini is a replacement. The first one had battery drain as well. My iPhone 7 drains 0% at night and is still on iOS 13.
I don’t believe optimizing is still going on after 10 days. That wouldn’t be normal. At best, we are talking 48 hrs.
More than likely, there are one of more apps using location services and or cellular / WiFi signal is weak during the night.
On my mini, I am getting anywhere from 3 - 6% drain overnight (8- 9 hrs).
I’ve had mine for more than two weeks since I did a DFU reset, and only have around 300 photos on iCloud so it’s definitely not still indexing. There is nothing reported using the battery at night. I do only have two bars reception on 4G, but other phones left in the same bedroom at night seems to drain normally, like 1-2% per night. I’ve tried pretty much everything. Going to wait for 14.3, if that doesn’t fix it i will request a repair/replacement.
My guess is it’s a firmware bug. My current modem firmware on 14.2.1 is 1.14.06, and according to this: https://forums.macrumors.com/threads/ios-14-3-beta-2-bug-fixes-changes-and-improvements.2269270/ the beta 2 modem firmware is 1.31.03-4. So I’m hoping 14.3 will fix the issue.
Do you have location services on? If so, do any of the apps have access? Do you have 5G completely turned off?
It certainly could be a bug.
