iOS 11.4 battery drain

I installed 11.4 a couple of days ago. Battery life immediately dropped from 3 days to just a few hours. There are lots of people suffering the same problem and the only temporary fix would be to roll back to the previous version - except Apple has already blocked that move.

Please Apple, sign the previous version and let us all be able to get through a day without worrying about whether the phone will still be working before we get home - or better still fix the 11.4 problem.

I updated my iPhone 6 to 11.4 and my battery life has gone down 50%. The battery health has already gone down 2% since the upgrade (from 95% to 93%, meaning that it went down 5% in a year and a half and has gone down 2% in a week of having the upgrade). I hope they fix the problem before it destroys my battery. Apple blew it.

I also noticed a 3% drop from 100% to 97% in my 3 month old iPhone X in the past 2 weeks since the iOS 11.4 update. I can barely get 5 hours of usage time on it now when it was close to 9 hours prior to the upgrade 2 weeks ago. I really hope they fix this issue soon or all of us on this thread will need battery replacements sooner than the 500 complete charge cycles Apple references for peak performance capability. I am seriously considering installing the iOS 11.4.1 beta version since we can no longer roll back to the more reliable iOS 11.3 anymore.

Yes! I have an SE, I use it as a phone and some texting. Not games, music, movies, etc. I cab usually have a good amount of charge for 2 to 3 days. Now, without using the phone, having it at 100% charge at bedtime, wake up to a completely discharged phone. This is ridiculous! Wish there was a way to roll back. A phone, not being used, with cellular turned off along with WiFi assist disabled, should not be draining overnight, period.

My mini 4 is also running out of juice fast, but I use that a lot more so I monitor battery more often.

I have a iphone 6s one month old. After the ios 11.4 update my battery use at least 60 % during the night when the phone is not in use. This morning it was dead when i woke up and the phone had 65% battery when i left it last night. i always check that there is no apps running when i leave itfor the night.

using the phones alarm clock to wake up so now i cant trust the battery to last over night..... back to the old alarm clock with chiming bells.......

Yep. I had initially put it down the initial battery drain that you usually get with an update, but now well over a week, it is persisting with minimal usage. Noting what someone else said, my 3.5 yr old iPhone 6 had a "battery health" of 92% on 11.3.1 and this too has gone down to 90% following the update. I appreciate that it is not affecting all users, but clearly this is an issue and it would be good to get it addressed asap.

I have tried some of the suggested actions from this thread, to no avail.

I have a iPhone 7 and a 7 plus. The 7 has a three month old battery exchanged at the apple store, the 7plus is less than a year old. After downloading 11.4 both phones only hold a charge for less than a day. The 7 plus use to last for 4 to 5 days. My wife’s 7 also had a battery swap and her battery drains as well after loading. All 3 phones?? What is the issues?

Hi, It seems like the iOS version is faulty. I did fix the problem on my iPhone 5s. I downloaded the iOS off the internet and then restored my iPhone as a new phone from a backup. Because of this mess, I asked iTunes for a refund as I thought I lost everything including ringtones which I later found. Nevertheless, they did say that everyone should provide feedback.

I had my battery charged at 100% last night. Put it on the nightstand and this morning it was dead. I did the upgrade on May 29 so in a couple of days it will be a month and it is draining just as fast today as it did when I first upgraded.

We have the same case with both SE in our company.

Deactivating of Bluetooth, WIFI, cellular, tried Network Reset and Phone Reset - nothing works. Both phones run empty without usage over night. Both devices are only 2 months old and have battery health of 100%.

Hello Yatika, when you sign to Apple,look for specified device click on IPhone,IPad,etc. Then look for the Tech device and battery update. As you click, it’ll walk you through clear steps on Apples battery and updates. I wish you luck.

Have done that reset in the past to fix a bug in iOS 9. It didn’t work then. And no, didn’t lose a thing. Since it seems to be which band of WiFi I am on (no odd drain using 2.4 ghz band) I did reset Network Settings. I was hopeful but no. Even the iPhone X seems to be affected so I must be hopeful a fix is in the works.

My family uses android and all you do is pluck out that memory card and pop it in a new phone and nothing is lost. It’s like a reset all settings. Sigh. This one is a real problem.

Truly glad yours has recovered.

You should not lose any app data by doing a network reset!

I think that you should look at everything that the phone is used for!

Apart from Minecraft, is the phone using only wifi, is it using Bluetooth? ( Headset ) etc

Is mobile data on or off, are you backing up to the cloud? Too many questions to ask you....

I would suggest that you avoid doing any resets or rebuilds until you know what you are doing with the phone!

I agree - this is sad! iOS 11.4 was released May 29 and the battery drain issue seems to be quite widespread and no fix yet! Apple would know for sure the EXACT percentage of iPhones this is affecting given that most people opt to share their diagnostics information with Apple. "Arrogance" seems to be the correct word. I'm sticking with Apple for my phone though - I like how iTunes syncs across all devices.

Not only does my battery drain like a faucet’s on, but my tablet runs MUCH hotter and recharges more slowly. I’ve turned off everything I can find, and no joy. Had absolutely zero issue before the update - was 100% before I fell asleep, like every night, but the morning after the upgrade - was completely drained, had to charge forever to even power on. just using Overdrive to read a book drains it noticeably in an hour. Please fix this!
