iOS 11.4 battery drain

My iPhone 6 was working perfectly fine until I updated to iOS 11.4 and ever since I did that my battery is draining rapidly even without me using it at all. I used to go a full day without charging it now it may last half a day. I am just wondering if something got turned on with this new update that I have to turn off to save battery life. It is just weird I have not done anything other than update the iOS and now this happening. Any help would be greatly appreciated.

To everyone having battery issues on iOS 11.4.

What has everyone tried?


Have any of you tried a hard reset of your iPhone 6/6S by holding down both the Home and sleep/wake buttons until your iPhone goes to black and restarts with Apple logo, then release the buttons?


How much free data storage space is left on your iPhone?

iDevices need to always maintain, at the very least, between 2-3 GBs, OR GREATER, of free data storage space.


In Settings app, under General settings, Reset panel, at the right bottom of the list, Reset All Settings.


In Settings App, Battery, check to see if any apps/processes are eating up your battery.


In Settings app, General settings panel, turn OFF Background App Refresh for any apps you feel do not need constant data updating/Internet updating in the background when not using the an app OR turn OFF Background App Refresh entirely/globally for the entire device.


Do the same in the Settings app under Notifications.Turn off notifications for apps you do not think you need notifications for and/or edit the different ways you receive notifications to help with performance by not always using all the notification methods together.


In Settings app under Mail, you may want to set a longer fetch time or set your iOS Mail app to only manually fetch your mail ONLY when you launch the iOS Mail app.


In Settings app (NOT from the iOS Control Panel) turn OFF Bluetooth when not using any Bluetooth devices.


Also, in general, if you want a faster IDevice, on all of my iDevices, I turn off most of the iOS motion graphics eye candy, by simply turning ON Reduce Motion in Settings app, General, Accessibilty settings.



Make sure you aren't running 30 -50 OR EVEN MORE background apps in the iOS 11 Control Panel/App Switcher.

If you are, you need to quit the bulk of these background running apps by tap and hold a finger on an app window in the switcher and slide your finger upwards to quit an app. You should be able to use more than one finger to quit more than one app window simultaneously.


Also, make sure you don’t have 20-50 OR A WHOLE LOT MORE of active website tabs running in the web browser.

If you do, greatly reduce the amount of active website tabs your web browser.




Some minority of user have been turning ON and leaving ON iCloud backups continuously backing up on a constant and daily basis.

If you are one of these users, in Settings App, tap your Apple ID, then tap iCloud, then find iCloud backup and turn off iCloud backup and only turn this on to do daily backups either when you are not using your iPhone for a prolonged period of time (like when you are sleeping), then turn iCloud backups OFF when actually using your iPhone.


OR


Only perform your backups on a lesser time schedule.( like twice a week, once a week, once every two weeks, once a month, etc.).



Any large amount of background running apps or active processes that have to constantly go out to the Web to fetch data ALL THE TIME is going to slow down ANY iDevice and also, severely impact battery life.



In addition to all of the possible fixes and solutions presented, another iPhone 6S user, in another single posting in the iPhone support communities, suggested to go into Settings, General, Accessibility, Increase Contrast and turn ON Reduce Transparency.

Your iPhone 6/6S won’t look as pretty, but that user reported that his iPhone 6/6S speed improved considerably.



If none of this, so far, has helped your iPhone 6,/6S,


What about doing a complete backup to iCloud or iTunes on a computer, then do a complete erase and reset as new in the Settings app under General, Reset then restore your backup from iCloud or iTunes?



If still no joy after the erase and restore, hammer Apple with constant feedback about the iPhone 6/6S issues here.


iPhone Feedback


http://www.apple.com/feedback/iphone.html


This is THE ONLY avenue to get Apple’s DIRECT attention to any and all iPhone 6 issues!

IF no one continues to post regular feedback about iPhone 6/6S issues, Apple will NEVER know there is an issue and will never correct it!


Cognizant Apple employees read ALL feedback generated from all of the various feedback pages and transfers the data to the appropriate Apple personnel , but NO Apple employees will ever respond with any type of direct, individual replies from the feedback you post.



Good Luck to You All!

[Tried to edit my post once the cable issue was solved.]

What is the freaking problem with Apple!?!? Are they **** bent on my next phone being a Samsung?! My 5S went from 70% to zero when 11.4 loaded! Red flashing empty battery and forlorn lightning cable. I restarted the phone twice, and it came back to 70, but started draining fast. My 6 was unfortunately already loading 11.4 by then. I will try to regress to 11.3.1 or any other working version. Both phones are in low-battery mode and plugged in. Not looking forward to traveling far from a charger at all. I have no confidence in Apple at all right now.

Jun 28, 2018 7:34 PM in response to tariqnisarahmed

And now I am finding out that 11.3.1 is unsigned?!? For crying out loud, Apple! At least you could have rolled out this idiotic plan of yours when the next Samsung Note model comes out. Now I need to decide whether to buy a Note 8 or stay pen-less in a 9. If this unsigned 11.3.1 won’t take, and I still have this problem tomorrow, then it’s over. But I’ll be joining the 11.4 lawsuits for sure.

Turning wifi off is a non-starter if you require wifi to assist your cellular reception in a tall office building or other cellular-unfriendly locale.


My 6 has gone down 12% today, but I drove to work with GPS on, sync’d my Garmin, and am typing reply now — this last bit, reading replies and typing mine has cost 3% of the 12.


My 5S has stayed at 100 so far, but I have done nothing to it other than check the lock screen.


The only difference from the epic-meltdown of last night has been that I charged both devices all the way to 100%.


If you are still having trouble after a good stint at 100%, that may be a sign to take drastic action. In my case, I have taken note that the next Note may be coming out soon.

Good info and many thanks. I will go that route.

It might be in Apple’s best interest to change the name of this forum or to better define the purpose to “consumer to consumer” hints or comments.

We are all trying to incite a riot with the hopes that Apple might do something with all good intentions to get our expensive phones fixed when it wasn’t the consumer’s faults. The forum does show that that this is not an individual operator issue.

Thanks for clearing this up.

Jun 29, 2018 7:07 AM in response to DanNewnan

If I had to guess I would expect the ”comments” on this discussion haven‘t gone unnoticed by Apple (with or without the aid of a riot!), and the fact that those using the lastest beta are seemingly reporting better battery life goes some way to back that up.


It’s just sometimes, no matter how frustrating or painful the issue is, all that can be done is sit back and wait, I like many others would like Apple to be a little open about things, and I wouldn’t think it would dent there reputation to have an area on the web site that kept users updated on known software issues, a little like that for there various services.


But until that day comes, we have to use what’s available to get info to Apple and then sit back and trust a resolution will be forthcoming no matter how hard that may be with a problem like this that literally staring you in the face every time the device is used.

I wish I had your confidence in Apple. Earlier this year I went through the same thing we're experiencing with an iOS update ruining my batteries. They finally gave up and told me I had "vintage" hardware (myiPhone 5 and iPad 3). They no longer service them and my only solution was to buy newer ones. I got a new iPhone. But this will be my last one.

Fool me once, shame on Apple. Fool me twice, shame on me.

Jun 29, 2018 8:05 AM in response to Magmason

They can will the battle and lose the war.


If this isn't fixed and I am finally tired of having to keep my phone plugged in all the time, they won't get any more of my money. That is all any of us can do.


I have had Android before and there are some Apps that they don't have.

However, I need a mobile phone that is mobile.


PS: My iPhone 6S does have a middle finger emoji. I guess it was meant for this purpose.

How do I downgrade? This 11.4 release is horrible on my 6s. Makes my phone worthless since the battery is draining so fast. The last time Apple did this on the 4s people were forced to upgrade HW and the cost for change is too high and not feasible for a family. I’m not doing this again. This is terribly poor customer service Apple!!! It impacts not only customer satisfaction but also customer loyalty.


Can someone tell me how to downgrade?

I have opened a ticket with Apple as suggested on your email below and no news from Apple until today.

People are completely frustrated of course because Apple just a new IOS and it is us who are getting prejudiced. I am personally very disappointed with Apple, without mentioning that I’ve already spend a fortune (I presume like many other people) with batteries, screens etc - all this because I was thinking it was my phone! Let’s be honest, since the release of the IOS 11.4, Apple has not taken any responsibilities ..

Just got off the phone with Apple Support. They were no help at all and said iPhone 6 Plus is an old phone and incompatible with new software update. He suggested I check my battery health, location settings, wifi etc. I had checked prior to calling and all were good. Apple is trying to place burden on the users, and not accept responsibility for bad update. Apple has no plans to fix the issue. He suggested I buy a new battery! What a scam - there was nothing wrong with my phone until I installed iOS 11.4! And a two year old iPhone is considered old - seriously? Curious logic, considering my husband installed 11.4 on his iPhone 5s and it works fine. Wake up Apple!

Texts and FB Messenger, some use on FB, Emails, made two short calls.

Surfed the web for a short time.

Did not want to push too hard first time.

I’m sure many others use their phone more than I do.

WiFi is off now. Looking to see if it completely drains the battery from this point.

This past Sunday I charged it normally, left it on with no soft reset. No use. Wanted to see how long it would last.

Completely charged ....lost 100% in about 12 Hours.

According to battery life info, I have 92% capacity use. Don’t know if that has any bearing on it.

Going to keep trying.
