I have been running all the iOS Beta 13.1/.2 since they have been release and haven't really had any issues until about a week ago. I noticed my iPhone X was dropping to 50% by 2pm and dying before I could get home where in before it would last until 11PM or so. I turned off almost all background refresh and keep the apps closed. I cannot figure out why it is doing this. A co-worker is having the same issue. I swear the back top 1/3 of the phone is warmer than the rest without use. I am trying the new final release that was issued today hoping it fixes something.

I'm on iOS 13.2 (not beta) as of this morning, and I've noticed unusually high battery usage on my XS Max in the past week too (with the previous public version). I've still been able to make it through the day just fine, but with less battery left in the evening than normal

Haven't figured out why it's happening yet. Will see if 13.2 helps.

Figured out one part of the problem in my case - ever since the clocks were moved back last weekend Optimised Charging has continued to operate on summer time. I must have not noticed it on Sunday, Monday and Tuesday, but today when I picked the phone up from the Qi pad it was only 82% charged.

Now to retrain the thing to charge fully based on winter time...

It’s definitely something in iOS 13.2; I was running the Beta and at one point, my phone, which was in my pocket and hadn’t been used for a couple of hours said FaceID would be re-enabled when iPhone had cooled down. Phone felt unusually warm; wouldn’t mind but I was in an environment where it wasn’t any higher than 15c ?

I had similar issues on my 11pro on iOS 13.1.3 or what the last version before 13.2 was. Then they just randomly stopped again after three days. I was close to replacing my device, but then everything was fine again... such a buggy piece of software..
Look at that overnight drain, just sitting there doing nothing..

Battery drain was bad on my 7+ last night but I assume that's because of the upgrade. I will check it in the morning to see how much it loses. Hopefully it will be back to normal.

So it still seemed to happen after the final release of 13.2, I saw that The Weather app was still using background refresh even after I disabled it. I saw it mentioned a few times and was one of the biggest percentages of my usage. I ended up deleting it this morning and am just below 50% now at 7pm and before that I would be dead by 4pm. Must be some bug either with The Weather channel app or iOS 13.2

Here's some fun battery drain with the phone doing something, but nothing special -- just Netflix.

I habitually watch a few episodes of whatever show I happen to be into at the moment while laying in bed before sleep, with some BT headphones. I was quite surprised when my 11 Pro max went from 100% charge to 18% after 5 episodes of "Another Life". I mean this phone has an OLED screen, a giant battery, and it's dark and screen brightness is minimal. This is on iOS 13.2.

Today I tried a similar test with my 2-years old iPhone X. Smaller battery and hundreds of charge cycles on it, but it's on iOS 12.4.1 still. Same five episodes, connected to the same BT headphones, but in a brighter room so the screen was brighter. I didn't watch the episodes again, but just let them play out. The first graphic is the iPhone 11 Pro Max on 13.2. The second one is from the iPhone X on 12.4.1.

Nearly 42 hours off charge and still have 4% battery, 13.2 improved battery for me on iPhone 11. Much better than 13.2 beta!

combined screen time for both days is 9 hours.

I have an XS. Same thing

Since iOS 13 I noticed the battery drained much faster in standby mode but when I'm actually using my phone it feels the same as iOS 12.

First day after 13.2 used 15% in 12 hours. Last night the drop was 6% which is acceptable. I generally use my iPad mini when I get home instead of my phone.

6% drawdown in 12 hours last night so that looks consistent. Two ways to reduce the drain: 1) archive emails (I probably have 10,000 emails across five accounts and archiving always improves performance and reduces battery consumption), and 2), charge my phone at home when I'm not using it (that is, don't be so lazy about taking my phone out of my jacket pocket and putting it on the charger when I get home).

My iPhone 6s is experiencing major battery drain. I have turned everything off (Background app refresh, locations services, mail, etc) and within 10 minutes my battery dropped from 98% to 53% after using Twitter.

Even with the battery capacity at 86% I’m having that same problem. I set it up as new without signing into iCloud and everything to be set up later and no SIM. The battery drain seemed okay. I decided to sign in to my iCloud and all hell broke loose. Dropped from 87% to 43% all while the device synced to iCloud and nothing else. I already got my iPhone 11 Pro so decided to trade in for a gift card at Apple. Don’t feel like scamming someone by selling for more money.

I suspect that the iCloud Server Sync problem is contributing to battery drain issues. It might be poking the servers too much or might have to keep retrying because of failures.

Interesting. I will check that. I am on an iPhone 6s, but have never seen battery drain like this.

It was in the first few minutes following the initial logging into iCloud. Server sync issues don’t apply. Please don’t automatically assume people for noobs. If you’d read my post right you’d understand that I was troubleshooting the drain.

I’ve experienced something like this when iOS 12 was initially released. With a battery change the problem was gone and the capacity was at 97% at the time. Now it’s the same thing all over again only about a year later.
The first time they refused to replace the battery and I wrote a scathing review about my experience. The next day I got a call from the store manager offering a courtesy replacement. I don’t wanna go thru all that again so getting rid of this piece of crap.

Yeah no usage and drain too here. I suspect it maybe watch os 6.1 or bluetooth related. Do you have bluetooth off just to test it? Guessing, no idea really

This morning I checked my iPhone 7+ and I had to enter my password as it apparently rebooted. It was at 97% which was a surprise as normal drain is 6% for 12 hours. It's possible that it was dormant or something for some part but it would be nice if 12 hours not in use was 3% battery drain. I will continue to monitor it.

I do see more Bluetooth disconnects on my watch and car. I think that this is why the pictures of contacts are sometimes displayed and sometimes not.

disable any background activity, archive all your emails, disable push on email.
That advice about disabling any background activity needs to be a little more nuanced. For personal email I agree for business email not having push enabled could be expensive.
