iOS 11.4 battery drain

I have big problems with my Battery .With 11.3 it was everything super good. Now when I let it overnight with 60% Battery- in the morning is my Phone dead!!!!!

This is very badly .Please correct this 11.4

My Iphone is 6S

APPLE NEED TO FIX THIS ASAP!!!!

I have an iPhone approx 1 year old. Was working perfectly with battery at 98% capacity. After upgrading to 11.4 it doesn’t last for more than 2 HOURS!!!! It also lags and freezes!!! FIX THIS NOW APPLE!!!!!

This is really not acceptable! I need my device each day. After 5 hours of idle and 1 hour usage, it reached 10%! ***? Are you kidding me Apple? You should hire some software developer from Samsung, maybe they do a better job than you!

What the **** is wrong with this ****** iOS 11? We have never seen so many bugs since Apple released iOS 11. That's a shame for such a big company! I can not go outside with my battery case anymore.

By the way: i'm using a iPhone 6s. Battery health status is 80%. It will be replaced next week at the Apple Store. Whether it is a software issue, it will not fix the battery drain problem. 😢

Trying the workaround with the 2.4Ghz Wifi Network now... As many people did before: restore did not solve the problem... so do not waste your time.

I'm having the same issue. BH=90% and since upgrading to iOS 11.4 it's been terrible. Battery barely gets through half the day. Apple: This release is an immediate battery drain issue. Please fix!!!

Maybe the best thing to do is what Ziebo did: downgrade to 11.3.1

Great suggestion.

Going to look into that today.

Ok. Thank you, Dave. That's very helpful.

What would be even more helpful is the fix to the battery draining iOS 11.4.

I hope the Apple support teams see all of our posts and push out a fix very soon. Today or tomorrow would work!!

I went to the Genius Bar and was told that all my settings and battery were fine. They suggested I reset my iPhone, which I did. Unfortunately, resetting my iPhone did not improve the battery drain.

So, I do think it is a problem with 11.4 since I never had this problem with previous updates.

Update after a few days :

My iPhone 6S Plus and my iPad Air 2 recovered their battery capacity since I connected them to a 2.4 Ghz WiFi network. As soon as I pass them on my 5 Ghz network, the battery drain come back. I hope it helps.

With all due respect Lawrence, it is clearly a problem with IOS 11.4. It just doesn't impact all devices. On my SE, I went from being at 70% battery left at the end of the day to having 20% left. My wife's SE was impacted as well. I was able to downgrade to 11.3.1, and the problem immediately went away. My battery health was 100%.

As of now, the root cause is unknown. If you are on 11.3.1, I'd strongly recommend staying put until Apple releases a fix. This was a huge hit on battery life and there was no feature in 11.4 worth the risk.

I absolutely agree that folks with this problem need to escalate to Apple officially, but don't expect that a battery replacement will help.

I have also been experiencing SEVERE battery drain! iphone 6s plus with a new battery installed October 2017. Battery drain only started occurring after updating to iOS 11.4. I get less than 4 hours of use following charging to 100%. Most recently have been experiencing iOS shutdowns when battery indicator shows ~50% battery. The shutdown ends in a reboot loop with the white apple icon appearing and disappearing. Then reappearing and disappearing...and repeat. Only fix is to plug the phone into a charger connected to the wall outlet.

This seems to be an iOS 11.4 update issue. WORST UPDATE EVER!

WTH APPLE???! I have been a loyal apple customer since iphone 4. Apple is losing is luster...defection is imminent!

Fix this now Apple!

I have seen that statement after every iOS update since 1.1 in 2007. The only thing that changes is the version number in the statement. So clearly, every version of iOS has had this problem since the beginning of iPhone time. Alternatively, it is something unique about the phones that have it, or it is something that failed in the process of updating. Your choice. There are around a half billion phones that have been updated to 11.4. If even a vanishingly small number of them have this problem there would be thousands of posts about it. Once it really was a problem, 6 years ago. There were 13,000 posts about it, at a time when there were only 100 million phones, and the problem affected only 5% of those phones. Today there are over 1 billion phones, and it is estimated that around half of them updated. If that same problem occurred today there would easily be over 100,000 posts. I see 90 in this thread, and a lot of those are repeat posts from the same users.

Here is a way to tell. Back up your phone. Restore iOS using iTunes and set up the phone as New. Do not log in to iCloud. Do not add any email addresses. Do not turn on iMessage or FaceTime. Do not add any apps. Check your battery usage for a day or two.

FWIW, neither of my iOS devices have exhibited any change in battery life.

This is first beta release of a new OS version. If you are surprised with things going wrong you have no business installing this. The point of a beta is either development or helping to report bugs not ***** about them here. Download the Feedback app and submit feedback or go back to the release version.

No, it is not the first beta of 11.4, which went GA 2 weeks ago.

Same problems here as well. I noticed under the battery usage, that I keeps seeing various apps with 'Audio' as the use case and it shows like 30% or more when the 'Audio' flag is there? I've seen in on Reddit, App Store, etc. Maybe a bug with the way it is handling apps and the audio engine? Either way, let's hope it gets fixed soon. I am not one to jump on battery threads, but this time I see it too!!!!

I have this issue with an iPhone 6. I had the battery replaced 2 months ago in the Apple store prior to ios 11.4 release. All good until 11.4. Battery drain is horrendous. 60% to 2% overnight with no use. They need to fix this immediately

The point is that "all over the web" is absolutely meaningless. Most of it comes from posts in Apple Support Communities, so it is simply positive feedback - People post a problem in the forum - the press picks it up from the forum - people in the forum simply quote back what was posted by them originally. Complete circle.
