iOS 11.4 battery drain

Oh dear, disappointing to hear that, I was hoping 12 had the fix. My SE is still OK after 2 days, phone restore did show temporary improvement and then deteriorated, perhaps the deterioration is coming, maybe in work on Monday although it seemed to be OK in work on Friday.

My iPad mini was also unaffected by 11.4.

The only way I can conserve battery is to switch to Low Power Mode.

Yesterday I was able to go from 7:30 to 2:30 and go from 100% to 69%.

This included 3 hours on WIFI. All on Low Power Mode.

My Battery Standby was about 2.5 hour greater than Usage so I wasn't using it constantly.

When I did start using for Hot Spot then the consumption went down rapidly.

It would help to be able to leave 100% on low power mode and not have it reset when it reaches 80%.

There also must be something running in the background as the internet (hot spot) is so much slower than before.

I have this issue and it’s so annoying. I used to be able to be on my phone for a whole day without charging and then charge it at night. Now since I downloaded iOS 11.4 I have to charge it multiple times. My phone went from 100% battery to 19% battery in 3 hours while on standby at school. This is serious issue and has been going on for days, apple needs to focus on this and fix it. Nobody knows how to fix it so it’s down to them!

Life is still better on 12 beta for me, it's 28 hours since I charged to 100% and now at 83%. It hasn't helped other people and I'm waiting for the power dam to burst. I started from a restore phone to new on 11.4 so I started from no apps, no old settings and no old data. Even with no apps, background app refresh and notifications off I got occasional rapid drain so I took the plunge and installed the 12 beta. I installed 1 app to control my Arlo cameras and I stayed with native mail for over a day before I added the gmail app. So only on 2 apps at the moment.

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.

I can only suggest everyone contacts them on that iPhone Feedback page to express their frustration over such a ridiculous thing, particularly their ignoring the issue. I would have been happily waiting if there was a little announcement that said we are sorry about this and are doing everything we can to fix the issue asap...

Anybody wondering why none of the big Apple news outlets are reporting on any of this either? This problem must be massive, considering how many iPhone have to be affected by this problem. MacWorld, MacRumors, 9to5Mac.....? Are these guys all on Apple's payroll too and were told to shut up about this? Just curious....

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.

12beta 2 is marginally better and with background app refresh set to WiFi only. You can then flick WiFi on and off for best performance. Today my 6S appears

more stable. I’ve passed on the feedback via the beta feedback app.

Same here. I believe the problem resides with WIFi. My router and this is with my phone near it is showing a 20% loss of signal which can cause the phone to work harder to compensate. I know it’s not a network issue because I have other devices I’ve tested and they get full 100% signal. My older iPhone gets 100% but it’s using an older IOS. I think there is a bug with WIFi and Apple refuses to address it. I’ve beta tested IOS 11.4.1 and IOS 12 and neither addresses the battery drain. In fact it’s worse then it is now on IOS 11.4.

Every single one of my current devices iPad Pro, iPhone X, iPad Mini, MacBook Pro has suffered from increased battery drain and various lags & glitches with latest iOS/MacOS update.

EVERY. SINGLE. DEVICE.

EVERY. SINGLE. TIME/YEAR.

In fact the best battery life and most glitch free experience I’m geeting is ironically from my iPhone 5s on an iOS 12 public beta1. The 5s was practically unusable prior to the beta and now it’s the least buggy of all my devices. Moronic development & absolutely shambolic business practices.. The truth of the matter not only is Apple is gettin horrible in both implementation and innovation of hardware that is inline with current tech sector expectations with regards to support/R&D but the constant release of newer iOS/MacOSes that are full of bugs and blatant crippling of what they consider “older” hardware is absolutely ridiculous.

This company is so far removed from the company where Steve Jobs personally responded to an email I sent him regarding constant reoccurring kernel panic issues with my MacBook and replaced my MacBook Pro personally that it isn’t even funny. Never thought I’d say this but the leadership of this company is a total jokeat the moment. Sure it’s probably as profitable as ever but there‘s zero vision and zero industry leading innovation from the brain trust.

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.

It is mostly because of the usage of the applications or there might be some changes in settings. if it is showing battery maximum capacity as 90% then it means there is some issue with the usage of the battery. Try one thing, put the your iPhone in charge when it is 15% and keep it in charge till 100% and do not remove it from charging. let it drain till 15% again. Do this 3 times. and turn off few notification in settings. It might help you.

Really-the problem is, I also after updating my iPhone 6s Plus noticed that he began to lose charge twice as fast, now you have to charge it always and everywhere! Please fix this error in the update or return the previous firmware to all users!

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.
