Apologies for the million battery post, but the drainage seems concerning.

iPhone 11 Pro 256 GB, (over 100 GB free space) running iOS 13. I was running iOS 13 GM on iPhone X; I did get an Apple Update available that said iOS 13.0 is avaialable (on iPhone X) backed up my device before restoring from iCloud backup on iPhone 11 Pro.

I put my iPhone down at around 10:30 - 11 PM with 41% battery. Woke up at 6 AM with 22% battery...

Background apps are off, both times in the night (indicated in screenshot) were "home and lock screen" (maybe email notification) for 1 min and then alarm at 5:30 AM & 6 AM.

Background app refresh is Off. I don't have facebook, twitter, or any heavy pesky apps installed and usually go through all my settings to make sure phone is setup with optimal battery settings.

Is it just me or does 19% drainage for 7 hours of standby time seem really high?

Bump, same thing seems to be happening on 13.1

My iPhone X maybe dropped 10-12% MAX overnight and even that sounds like a stretch. this seems like a huge drain for the phone not doing anything.

I’ll test it on Friday, my phone is always on the charger at night so I haven’t noticed it. I have less drain that that while at work with some light usage though. I wonder if it is having trouble with WiFi.

I generally don't keep my iPhone on the charger overnight. And it sits on my nightstand that always has 2/3 bars for WiFi.
 
Well I was worried about this, but it seems iOS 13.1 wrecked the amazing battery life on my iPhone 11 pro. The main reason I wanted to upgrade was for the battery. Got this and iOS 13 was amazing with battery life. It was filled with bugs, but battery life was amazing. Now iOS 13.1. Not so much. Very, very disappointed. Why is it that Apple can’t get this right? I worry every time there is an update for the Apple Watch that is going to wreck the battery. It happens all the time.
 
If using beta profiles, always set up as now when GM is released or upgrading. Seems like you have running background processes.

After you restored, your phone had to reindex and synch the entire content of your phone which sounds like over 100 gb. It was very busy while you were sleeping. This is normal and should improve over the next day or two.

Yes you need to give it time after an update. Check again tonight I’m on 13.1 and overnight with most apps having background update my phone lost at most 2%.

So day one we might still see some drain, but day 2 should be better? I have been on iOS forever, but didn’t think about that.
 
Thanks for the input, I am noticing that the drain seems to happen more overnight for me.. If I am in an area with good cell coverage and don't touch the phone for an hour, my battery might go down by a percentage or two. However, in my building (brick) in the basement where my phone is overnight I get almost NO LTE / 3G coverage although I do have very strong WiFi with WiFi calling enabled. I will keep an eye on things these next few days, but am hoping that my phone isn't searching for a signal.. although my iPhone X didn't seem to have that problem.

Also, I was running on iOS 13 GM, (although that may be considered a Beta) since I got the OTA update notification I did update my iPhone X to the Official 13.0 version via OTA and then restored that backup to my 11 Pro.
 
I think the issue may be my phone constantly trying to search for a signal when in my basement, as the LTE / 3G is HORRIBLE (again I am connected to WiFi though) I charged my phone today and took it off the charger around 11 AM at 97% at 3:05 PM it was still at 97% (I maybe sent a text and refreshed safari.

I don't remember by iPhone X ever draining at that rate..

I wonder if there is a setting to disable cell searching?

I had the same problem on my XS and then my new 11 pro Max. I hooked it up to Xcode and saw the healthd process was taking 95% CPU. I opened the health app and it downloaded my health data from iCloud. I took it off the charger 6 hours ago and my battery is at 85%, I think that fixed my issue maybe that can help you too
 
I actually have health data turned off to help with battery. I generally don't have my iPhone plugged in overnight so iCloud backups aren't running overnight..

I think it's the cell search that's killing me.

That still seems high drainage though maybe you can download Xcode and see if there is a process taking up too many resources.
 
Low/weak signal could cause this IMO. Have you tried using Low Power Mode while sleeping? If you are on WiFi I don’t fully get why there would be an issue with cellular signal. My 2 day old 11 Pro is on it’s second full charge cycle. I came off charge today at 7:30 AM. It’s 5:00 and I have 71% remaining.

I want to say DFU it.. but it being so new I might return/re-buy if it keeps happening.

I have not tried using Low Power Mode, I can't put my Phone on Airplane mode at night, I have to be reachable at work overnight in the event our system is down. What's strange is that it is only happening at night in my basement at my apartment (brick building) During the day standby is fantastic (a little over 3 hours standby and the phone didn't drop a percentage!) I have NOT tried resetting network settings yet, but may pull the trigger on that tonight. I have quite a few WiFi networks saved though lol.

I have sprint and tried dialing ##873283# (Update) and don't see any carrier updates available yet though.

I don't recall having drain issues like this on my X, but was at 88% battery health and generally charged the phone at my desk the next morning.
 
Sounds really high. I have an 11 Pro Max and got 4 days of light usage out of the box / before charging it for the first time (and I believe it was only charged to like 80% out of the box). My guess is there's some background process eating up a bunch of battery life, or maybe a combination of things. I would give it a few days and see if it calms down (maybe it's just some setup stuff).

I actually put my phone in field test mode to see what it's cell signal was and I am at "-129"

Apparently -40 and less is excellent, closer to -140 (max) is horrible and pretty much means no service.

That has to be my issue, I am going to chat with Sprint and get an airwave sent to me.
 
Try out 13.1.1 and report back about your overnight drain. I’m curious about this as well.

Updated as soon as it was released earlier today.. at work standby time was perfect. Almost no drain.

At my apartment I am still seeing massive drain. Every 30 seconds - a minute I am seeing the location icon show up on the status bar for a few seconds and disappear. Even with all apps closed. I have all necessary apps (gmaps, apple maps, uber, etc) marked to "when using the app" the ONLY system services that have locations enabled are: find my iphone and wifi calling.

It has to be my lack of signal...

When I reported the horrible signal numbers from earlier that was on the main floor of my apartment.. when I am in my room in the basement I cannot even get numbers when it field test it just says waiting for update. 1x and NO data/signal speeds at all.

Sprint is sending an airwave, I hope that helps.
 
So I set up my AirWave and am pulling 50 Mbps Donwload on LTE which is WAY better than what I previously had (was getting .1 Mbps donwload). CDMA, LTE, VoLTE are all green on the back of the airwave. Took my phone off of the charger last night at 11 PM, watched a 20 min youtube video, sent a few texts/emails this morning and my phone is at 89% at 9:45 AM.

So all in all not too bad, but I still think it should be a bit better. My brightness is turned down, no background app refresh, disabled Siri suggested search.. I have the phone optimized pretty well for battery.

What's strange is that I am constantly seeing the location icon on the status bar of my screen. Even with all apps closed.

I would say every minute or so, it shows up for 10-15 seconds. I have attached my Location settings (hid one app for work for privacy, but rarely have that app open) am I seeing that icon because the phone is alerting me that an app I used has used my location in the past 24 hours? If so, Why does it constantly show up?

Any reccomendations on locations settings for system settings / battery level or insight on why the location icon is always showing, is it normal?
