Battery drain iPhone 11 pro

So, iOS 13.2 is out and the battery is working as it should now on my iPhone 11 Pro.

I urge everyone to update and check.

All right, I think the issue is gone now. I’m in my second day of normal battery consumption. Maybe the drain will return, but for now I’m good.

so, what I did:

1. it was not Siri. Turning listening off didn’t improve drain.
2. I did network settings reset, after reading that might help.
3. I checked my mobile operator network settings. Usually they are filled automatically. In my case optional LTE / 4G part was not filled, so I took my time to fill it. It is explicitly market as optional though.
4. Checked for rogue programs. Nothing. But just in case I disabled background for Twitterrific. Don’t think it had any effect; reporting it for completeness.
5. Restarted the device.

I don’t know what changed. I wish I knew. For now my bet is on the network reset.

After this issue was fixed for me few updates ago I only get high battery drain when my mobile traffic cap has been reached, I.e no mobile internet.

First thing you should check is battery stats to make sure there’s no app that’s is responsible for all of this power consumption.

Another sign is the background consumption during inactivity. More than 10% of battery disappeared overnight? Then likely you have the drain.

I think that after a day of normal battery consumptions the drain came back. I noticed immense heating when using Safari on the road, and the site I was on is pretty simple with nothing fancy going on. Battery history showed me nothing of interest, but I'm sure the browser is not to blame here.

Now I remembered I had an issue with Siri and power consumption with iOS 13 beta and old iPhone X. I had to disable listening to "Hey, Siri" to get back to normal, but the issues like that are OK for a beta.

So, I'm going to turn off listening to "Hey Siri" in settings and check if it will impact passive battery drain on my iPhone 11 Pro. Will keep you updated.

While I stopped seeing the drain on my iPhone 11 Pro since 13.2, what you describe is familiar to me. Can you compare power consumption while commuting vs while not moving the phone from the same place? My commute always gives the biggest impact on the phone's battery life, regardless how I'm using it. And the worst impact I had was when I ran out on traffic allowance on my mobile data plan, so the internet was cut off on he phone. Something made it infinitely check for connection I guess.

Hi all

The problem has unfortunately resurfaced in iOS 13.2.3 for me as well. Same triggers being use of Apple Music over bluetooth peripherals, and symptoms being:

1. Heating up
2. Battery drain
3. Unresponsiveness of Apple Music and repeated crashing.
4. Lag in settings and other native Apple apps.

Just to note, I've used third party podcast apps and they stream fine over the same peripherals so I suspect the source of the problem is Apple Music.

See battery screenshots attached, and its extremely concerning especially the first screenshot showing battery levels above 70% dropping to 50% in less than an hour between 1pm to 2pm today.

This is incredibly frustrating as otherwise the iPhone 11 Pro is an amazing device. I aim to try and obtain a new device at the Genius Bar to see if the problem is contained to several defective hardware units.

I have an iPhone 11 Pro with iOS 13.1.3 as well and I’ve experienced significant battery drain / rise in temperature when Apple Music is running. When I play music which has already been downloaded on my phone (on speakers or Bluetooth) or simply clicking to ‘Browse’ and the phone is loading my preferences, it triggers instant battery drain and a temperature rise.

I stop it by quitting the app and shutting down. I’ve just done a hard reset and the problem persists.

If if assists, the problem first arose in iOS 13.1.2 for me, and the morning after I updated my lines MacBook to Mac OS Catalina (and iTunes therefore no longer exists in my environment).

I believe this is an iOS / Apple Music issue and I hope Apple fixes this ASAP.

Hi all - update on the issue. I’ve done a hard reset and the problem went away for a good day or so before resurfacing. Same symptoms - occurs when using Apple Music, more often than not via a Bluetooth.

When superheated phone performance is drastically reduced.

Apple devs should definitely take note and fix ASAP.

Thank you for your update, I have also noticed that my iPhone 11 pro drains more battery when resetting network settings ( it couldn’t provide me with internet on my home wireless network using Apple Airport access points) “issue appeared after iOS 13 update” on most of my iOS devices , so I was forced to do a network settings reset in order to gain an Internet connection , after restart , the phone tends to gets warm and the battery starts to drain , so I let the phone rest for a while without using it and the battery drain level goes back to normal , it seems that there’s something that triggers a spike in processor activities which leads to heat that leads to battery drain! This happens to me every time I reset network settings!!

don't know the root of the cause but there’s something in iOS 13 that leads to sudden processor activities.

Hi VikWorldwide

I've kept tabs on this since 13.2.2 and although the problem went away for a few days it is now back in a big way. Same symptoms as before and it always, always is triggered when I start listening to Music on a bluetooth device. It is happening to my device right now as I post.

To answer your question - the first screen shot in my previous post was during my commute, the rest showed random battery drain contributed by Apple Music background activity throughout the day while I am in the office / out walking.

So i have iphone 11 pro , i have been facing this draining last week , but after i switched off the VoLTE off , the mobile have been working fine and perfect , not sure if it is the root cause , but it seems to solve my issue

Network reset on the phone or the internet router?

Okay, so after network reset the problem gets back it seems. But in a weird background draining-while-doing-nothing way. I'm not sure if it is even the same problem?

Here's what happened: yesterday I noticed the dreaded drain returned, eating 20 percent in a couple of hours of battery for making few photos. So, I did network reset again, then charged the phone to 100%. Then I didn't use it, just checked the battery level.

If you look closely you'll notice that for the first few hours background consumption is basically flat. I checked the percentage and it was the way it is shown here. Then after 10pm something happened and the battery started on its steeper way down. Here's the kicker: there's no app to account for that in battery history. There's only Siri and home screen in some periods, and nothing in the rest. I bet it is some system process that don't appear in the history as a separate entry at all.

Maybe this background drain is a separate thing, and maybe it isn't a problem at all. The phone never got warmer when it was laying down doing nothing, unlike high temp yesterday.

Currently, I'm out of ideas what to try next

I can report that after iOS 13.2.2 system stabilized for a while and had less battery draining , but not until I upgraded to iOS 13.2.3 where it all changed back to worst! devices heats up on start or restart which is completely weird !

I guess the new update caused more problems than it should have solved!

I tried the network reset and it appears that the battery is better. We'll see within the next day or so. Thanks for the beta!
