iOS 11.4 battery drain

The problem is that so many people have complained about battery issues after almost every update that this one gets lost in the shuffle.

This battery issue is far different in my opinion. It is a dramatic loss in battery on my iPhone 6S after 11.4, without any other changes. And happens just letting the phone sit over night. And my battery is 95% healthy.

But you will see people saying 'it's only your phone', 'you need a new battery', 'reset', 'restore', 'turn everything off'... But none of that works and Apple can hide behind it because batteries always have issues and people always complain.

In this day and age with Apple taking the supposed high road on privacy issues, why are they silent?

And Jaeger is right, how ironic this problem is only killing batteries faster!@

Same issue. iPhone 6s with 11.4 updates. Phone's battery is draining like crazy overnight from 100%-95% to 10%-0. Battery health went down as well after update from 91% to 84% and it keeps going down.

I have the same issue. 6SPlus. I can't get through a full day anymore on my phone. I just took it off the charger at 8am at 100% and it's 12pm and already down to 40%! And I haven't even USED the phone except a few checks of email. There is definitely something very wrong. I just had a new battery put in a few months ago and my battery performance is at 98%. So the battery is fine - it's the software or some app used by the updated software that is draining the battery to nothing. Initially my firefox browser indicated the most battery use - so I uninstalled it -now my Outlook app is showing the most battery use. Either these apps aren't playing nicely with 11.4 update - or it's something else related to 11.4. Apple needs to patch this ASAP.

While I can appreciate your frustration and I support any persons right to choose who they give there hard earned cash too, I’m not sure the grass is always greener... Let’s face it, if you had been a certain phone manufacturer user a year or so ago that device could have gone up in smoke inside your pocket, plus there temporary solution at the time was to limit charge capacity!

This run-away-battery issue that certain user’s are experiencing no matter how common on this forum (24 pages and counting) is still a very small fraction of actual iPhone owners, just count the names and then times by 100, 1000 or even 10,000 to allow for those that just don’t bother with forums, and you still don’t get close to a fraction of a percent of total iPhone sales over the last 5 years.

The issue must be unusual due to the fact the common ”Restore as New” fix doesn’t appear to make any difference, and that could be the reason why it’s taking a little longer to resolve, but I’ve noticed a few posts now that seem to give some hope that 11.4.1 beta does in fact correct the issue. But as we’ve seen in the past what’s in a beta doesn’t always continue through to public release, so time will tell.

As I’ve stated before my two devices appear unaffected, but I’m not sure why. I don’t use Two-Factor, Mail is still old style POP, haven’t setup iCloud Messages yet, don’t use any of the iCloud Photo options or iCloud BackUp (again still old school using iTunes), so may be that’s allowed me to dodge the issue.

Anyhow, best of luck with your Android device, which ever one it is!

That is certainly true. Everything is software now and updates are the norm. Unfortunately all possible variables are not tested before the revisions are released. I have seen this first hand in the automotive audio industry.

When I look at all the "advantages" to 11.4 there are not any that I need or want.

I will certainly do much more research before I download newer versions. My other phone has NOT been updated to 11.4 and WON'T be. No problems with that one.

I too am having the same massive drain issue since the May 11.4 update. My battery health is at 98%. Since the last 11.4.1 came out it has lessened the rapidity of the drain- but it is still obvious. I would like to see a response from apple in regards to their intent to fix this major concern or if the intention is for us all to obtain new devices.

I didn't update until a few days ago, and I seem to be having the same problem with my iPhone 6. It had a new battery installed in February, but often, when I'm using it, it seemingly plummets from ~50% battery life to "shutting off" within a few minutes of use. This is a new development after months of great battery life and only showed up after allowing 11.4 to install. I was getting through an entire day and maybe hitting 20% in the evening with heavy use. None of the apps seem to be using an unreasonably amount of battery life. It all but renders the phone unusable.

I took my iPhone 6 to the local Apple store and the tech guy insisted it's not iOS 11.4 or had anything to do with the wi-fi -- so he reset my phone to factory settings.

That may have helped slightly, but it didn't solve the problem. The battery still drains much faster than it used to when it was iOS 11.3. I have to charge it at least everyday, even though I use it very little. I charged it before I went to bed last night and the battery dropped to 70% charge when I got up this morning. (If I turn off wi-fi overnight it doesn't drain at all!)

I used Safari for a few minutes and I literally watched the battery percentage drop while I was using it. My phone is useless.

Oh, I didn't backup my phone before he reset my phone because the new iOS changed my settings to iCloud backup, which I don't like to do (I prefer to backup to my laptop), so I lost all the current info and text messages when he reset it.

I've had it with Apple.

I have my phone with factory setting now and the battery drain seems to be less.

However it isn't much better than a flip phone without my data.

Welcome back to the 1990s.

I will refresh my data from back up tomorrow to see if it is any better.

I wouldn't be surprised that the tech support people are not aware of the issue as Apple seems to be a very secret company.

I have an iPhone 6s and after the update to 11.4 my battery life is horrible. I’ve noticed it is when on Wifi. This is ridiculous that a company like Apple cannot iron out these bugs prior to a new update being released to the public. This and the whole battery throttling debacle really makes me want to switch to another branphone.

Hello Community,

I may have some good news.

I began to routinely call 800-MY-APPLE and one day Lisa answered. She explained that she normally does not take phone calls but did today just to help out the team. Lisa said she was a supervisor. She was unaware of iOS 11.4 causing battery drain until I was able to lightly nudge her to take a deeper look. She confirmed that engineering may indeed be aware of this problem. She kindly opened a case (as a supervisor) and after the weekend, she followed up with me after she had follow-up from engineering. She collected the information from my iPhone as engineering requested. I have another session scheduled with her for July 4, 2:00 PM EDT to collect more info (logs) from my iPhone after it has rapidly discharged and I can connect it to iTunes.

Hopefully, this will be behind us soon!

It's in 12 beta 3 as well?

What a joke. After all the problems with batteries and the battery replacement program, Apple releases 11.4 to further destroy batteries!

This issue is clearly WIFI-related according to a multitude of posts. Must affect many 1000's of users who have no clue what's wrong.

Where's 11.4.1 final already to fix this? Apple's silence on the issue is surprising.

If you Google 11.4 battery drain issues you will find several articles on the problem and possible fixes.

Interesting that GottaBeMobile on 4/5/2018 reported 11.4 Beta with battery drain issues.

Apple: Why do Beta testing if you have your head in the sand? Don't ask if you won't listen.

I observe this problem on the iPad Air 2 with the A8X processor, almost the same as in the iPhone 6. The tablet from the moment of development on 11.4 began to work for 1.5-2 hours less. At night, a noticeable charge goes to nowhere. At the same time, I do not see any problems on the iPhone 8 Plus. The same 6-8 hours are active.

Now before you jump down my throat I agree there is a real issue regarding 11.4 release, but it’s not impacting everyone. I’ve posted previously and my X and iPad Mini 2 still remain unaffected, why I’m not sure and this could be the reason why it’s taking a while for Apple to resolve.

A lot of suggestions have been put forward in the 50 odd pages (which indicate it’s WiFi related) but you are the first to mention contacting a CEO, why don’t you send TC a mail with a link to this discussion and kindly ask for an update explaining the lack of feed back regarding the problem is as bad as the problem itself.

I personally believe they are working on a fix from the few reports I’ve read on other web sites but the concern is it’s not being widely reported, which is strange considering how many it seems to be affecting.

Anyhow, if you do decide to contact TC please let the discussion know the response.
