Battery drain after updating to iOS 13.3.1

I’m on the EXACT same boat as you @impulse_telecom. 6s owner and the 13.3.1 update bricked my phone making it completely useless. Battery health is 98%, but after a full charge it will only last a few hours.

Did you try going to the Apple Store? Any help there? Apple stopped signing iOS 13.3 so you won’t be able to install previous iOS.

Yes, I saw the 13.3 download stopped being signed minutes after I got it. I tried going back to 13.3, and everything seemed to go well: phone in recovery mode and new 13.3 iOS loaded to phone from iTunes, phone goes to initial setup dialog, I pick set up as new phone, and I answer questions, then the last step was a forced update to 13.3.1. Arrrgh! The only choices are back and continue. There’s no skip option. Exercise in frustration and a couple hours burned.

There’s a little conspiracy theory bubbling up here. I have an iPod, iPad and iPhone X that all updated at the same time as the iPhone 6S and all the other devices are NOT showing and unusual battery drain. I can see it would be convenient to get us luddites that are still using 4.5 year old iPhone 6S to update to a shiny new iPhone 11. I’ve got other bills to pay and I don’t really want to be paying on a mortgage for an iPhone 11. I really like (other than this issue) my iPhone 6S and I want to stick with it.

I have not been to the Apple Store yet. I found a new old-stock never used unlocked iPhone 6S model 1688 on line for only a little more than the cost of a battery replacement. I was going to transfer to the replacement 6S, but what I am reading here makes me believe I should wait a few days before I risk having the same thing happen with a replacement phone.

Edited: to fix spelling error.

I have and iPhone8 and have had a number upgrades done over the years and never had such a noticeable battery issue in the past. After the 13.3.1 upgrade few days back even if charged at 100% it dies without any usage within 12 hours. The phone uses 12 GB out of 64 GB... basically the iOS and a few apps. This does not seem like a re-indexing related issue and even if it does re-indexing it should not take days.

. Its very frustrating ,im on ios 13.3.1 i have a new iphone 11 , i just used it sicne two weeks ago , the battery is terrible , after 4hours the battery goes from 80% to 19%

apple need to do something about this problem .

Update: iPhone X is also affected by the iOS 13.3.1 update.

Normally, my iPhone X is a backup device and I leave it in a drawer with a 50% charge and turned off. This morning, I charged the iPhone X to 100%. I carried the X for 10 hours, and charge had decreased to 88%, which is possibly slightly more than usual, but within uncertainty. This evening I used the web browser to look at a web page on Walmart and the charge dropped 7% in about five minutes while connected to Wi-Fi and the phone got very hot. That is very unusual. Normally, that type of browsing would have used 1% of the battery at most and the phone would not get hot.

I am sure this problem has be be affecting a lot of owners. A fix is needed quickly as the battery drain severely limits the usefulness of our devices. Both the iPhone 6S and iPhone X now get very hot to the extent that I am concerned the internal electronics or battery could be heat damaged; obviously the interior of the phones must be even hotter than the outside of the case.

The situation is really terrible and is in fact much worse than the original battery-gate where phones were being throttled. At least a throttled phone worked. Now we have battery roulette where one can never tell how long a presumed healthy battery will operate the phone.

There is apparently something quite wrong with power management, especially as it relates to the graphics. I have noticed both an iPhone 6S and an X getting hot to the point where they are almost uncomfortable to hold while doing something as simple as scrolling up and down in Apple’s Settings App. It does seem that the heating and battery drain don’t happen every time, but scroll a few times and the issue is almost certain to occur. The heat is intense enough that I am concerned that internal components or the battery itself could be permanently damaged.

I have never dropped or hit the two phones where I have witnessed the issue, so I presume there is no physical damage responsible for the issue. It also seems like more than mere coincidence that both phones suddenly began having trouble exactly coincident with being updated to iOS 13.3.1. Apple should forget about iOS 13.4 for now and concentrate its mental energy on fixing the current issue.

I will appreciate any help:

i upgraded to the newsr operating sistem and during the day battery lasts as long as before.

but when I go to bad and I turn "flight mode" on, is where magic happens and battery drains for 20 percent in one night. It drained for 2 percent when being on 13.3. version of ios.

is there any explanation or is it a bug?

thanks for any help

To everyone: this is an iOS 13 problem. I’ve been dealing with this since September of last year when it rolled out. Given, I have a 6s, but I had replaced the battery two years ago. It’s still at 93% life. Everything was great until 13.

My battery drains sometimes in 20 minutes. Most of the time it’s between two or three hours. This is when I’m not using it!

My battery has fallen 23% while writing this.

I’ve tried all the “solutions”. Nothing is “solved”.

Apple will do nothing. If they haven’t by now they won’t. They either don’t know the problem, or they know and can’t fix it. It’s up to you to decide which is worse.

Im sick of the indexing excuse!

But hey, I read 13.4 will have 19 new emojis to ease the pain 😀🤮😂

The Galaxy is looking better all the time. Capitalization intentional.

I am not very optimistic we will see an answer in this discussion thread, but it is still important not to be a lurker and post anything at all, even if it is just, “me too,” if you are having the battery issue, to keep this discussion fresh. This reminds me of the 2006 Mac Book Wi-Fi drop-out issue thread that had thousands of complaints. There was never any acknowledgment from Apple at all until an OS-X maintenance release over a year later mysteriously fixed the issue without ever an acknowledgement the problem existed or any mention of a Wi-Fi bug fix in the release notes.

I agree: if this issue isn’t fixed within days, I am ready to dump the 6S and X iPhones I have and go back to using an Android device. The battery issue is obviously a problem across iPhone models as new as the 11, so apparently the only way to escape the issue is to change brands altogether. I had Android devices for close to ten years before I switched to an iPhone and in all frankness, the two systems aren’t that different in usability.

As it stands, the iPhones are not really useable unless they are plugged into a charger. At home or office, the phone is now constantly tethered to a wall charger and I now have a charger in the car so that I can be sure the phone has power in case an emergency situation arises. Carried in my pocket, I have no way to tell if the phone will suddenly lose power and shut off.

I started 3 or 4 posts on this issue with 13.3.1. So as not to repeat please view them. That being written, I agree this is a 13.3.1 problem and if tech support doesn't fix your problem I suggest a hand written or typed respectful letter to Mr. Cook to make him aware of the situation.

Yes, I have same problem ! I have iPhone 11 Pro. Battery on my iPhone it was very good and after I updated my iPhone from 13.3.0 to 13.3.1 very bad it’s not hold too much now . Now I must changing my iPhone everyday before I updated just twice in weekly.

Someone noticed ‘iCloud Keychain’ was using an average of 93% of the CPU on their iPhone which could potentially be the culprit.

See the full post on Reddit here: https://www.reddit.com/r/ios/comments/f7x8xv/a_solution_for_excessive_battery_drain_in_ios_and/

Long story short: Turn iCloud Keychain on/off/on

Settings>iCloud>iCloud>Keychain

It seems to vary which application is reported at the top of the list. One time, the battery dropped from 95% to 62% in about five minutes. When I looked at Battery in the Settings application, it showed that Settings had used 80-some percent of the power in the current sampling interval. That seemed to be a crazy number because I had probably used Settings for less than a minute just to check the Battery. Other times I’ve had Safari show up at the top of the list with a similar seemingly exaggerated battery percentage

Something definite I have noticed is that the phone will become crazy-hot in within just a few seconds even when doing little, if any, activity that would be CPU or GPU intensive. Something as simple as scrolling up the back down in the Settings application seems to touch off the issue. I downloaded Lirum Info Lite to try to get a better idea of what’s going on. Lirum Info Lite does not report GPU activity. The reported battery use reporting agrees with what the Settings app shows (not surprising) and the CPU activity looks normal: no weird 100% spikes.

I was lucky enough to talk to a manager at Apple (no idea how this happened) on Monday. She reports directly to the engineers. Supposedly. We spent almost two hours troubleshooting, and in the end she took all my logs for the engineers.

She called me back today with the results: they say it's a hardware problem.

I don't believe them. My battery was working great until September of last year when 13 rolled out. The problem started immediately after that and hasn't improved. It's not hardware.

She said the engineers said it's something like the BMO or BMU with the battery ( I asked three times and still couldn't understand what she was saying, she didn't know what it was either). Not being an engineer I assume BM is Battery Management...something.

She said it was an older iPhone problem, which from the responses here and other boards, is clearly not the case.

Her solution: Battery replacement.

At my cost.

$49.95.

Again.

For the second time.

This would be the third battery I've had in this phone. Yet Apple doesn't have a battery problem. Never has.

I'm not going to spend $49.94 on a phone that's worth $80, especially when I'm getting a 5g phone this year. It's not that I can't afford it, it's the principle. They're not getting any more of my money.

Don't bother calling Apple about this. They will not help. They don't care.

We are just supposed to deal with it.

Apple just lost a customer. I suspect they will lose many more because of this.
