iOS 11.4 battery drain

Instead of apple being helpful or trying to fix the battery issue they delete a post because I mentioned iOS beta 12 and that the battery issue remains. Instead they have us wasting our time trying to get a fix!

Important UPDATE on iOS 11.4.1 - I can report I charged my phone last night and unplugged it at 6:59 AM with 100% battery charge. It is now 10:17 PM (15 hours and 18 minutes) and my iPhone 6s is reporting 39% battery charge. That is good and a major improvement from iOS 11.4 and is similar to iOS 11.3.1 - I can sure live with that!

Your observation is well worth noting by others still experiencing this is, the rumour that 11.4.1 would fix both battery drain and camera problems have been around for a few weeks now, and again a report following it's release to the public still confirms that view (see last paragraph).

What might be good practice is to apply the update via iTunes if possible and also consider doing a forced restart when done, plus remember the device needs to "settle" for a while afterwards to allow any background "processes" to complete. After which hopefully your device should be back to pre 11.3 behaviour.

I updated my iPod Touch 6th gen 2 days ago too 11.4.1 and prior to that using 11.4 my battery with WiFi on would be dead on a full charge overnight. Fortunately 11.4.1 did fix the battery drain. However my iPhone 6s Plus is not doing so hot with 11.4.1 and is still draining heavy even in standby with WiFi turned on.

This is another thing that’s got me upset with Apple. Before I ever installed 11.4 my iPhone 6s Plus would register correctly in analytics reports but after 11.4 it registers my phone as an iPhone 8. Now something isn’t right, either we got bad batch files including firmware or Apple is slipping.

"They" are not going to fix it, unless you take some action to get it fixed. It is not a general problem with 11.4, it is a problem with your phone. Either you can go through standard diagnostic steps, or make a genius bar appointment and the technician will do it with you. Genius Bar Reservation and Apple Support Options - Apple

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!

when filling out feedback at https://www.apple.com/feedback/iphone.html I get to a drop down box for "which version of iOS are you running." This drop down does not even have 11.4 in it. It only goes up as high as 11.3

I also get the same "We cannot respond to you personally," message mentioned above.

Of course, that wasn't too detailed now, was it? 🙂

1. Download and install the configuration profile to your phone using the link I provide below (the phone will reboot).

2. Go to "Settings > General > Software Update" as you normally do with regular updates. Latest beta should appear - in this case 11.4.1 b3.

3. Download & Install update

Here are the instructions and configuration profile to download. You need to log in with your Apple ID using the device you intend to update:

https://beta.apple.com/sp/betaprogram/redemption#ios

The support on this forum is in the form of user to user help which obviously can only go so far, if you require direct support from Apple you need to open a Support Case File after which they will contact you and try and resolve. If the issue has been caused by an update even if your device is outside warrantee I've found they usually will take up the issue at no cost to the user.

I've noticed a lot of users have posted in this discussion when they should have really open a case file or even submitted feedback or a bug report. Venting ones frustration in this discussion although on first view might appear productive is after a while self defeating, there is no guarantee Apple are monitoring (although I would like to think they do) and any useful data may simply not get to the right department tasked with resolving.

Product Feedback - Apple

https://developer.apple.com/bug-reporting/

This is just my view but if all those that had posted on this discussion had instead/also submitted either a Feedback or Bug Report Apple may by now be getting the "message", at least with the latter you get a reference number and if Apple have already been made aware a "Duplicate" confirmation.

I contacted Apple support, which I recommend we all do. I’ve detailed my interaction at 11.4 Battery Issue.

They did not offer any knowledge of an issue or an immediate solution. They’ve sent my case to engineering. Perhaps thousands of cases from those of us frustrated may get some attention?!

Update to my post from last night. So digging a little deeper into my iPhone battery problem, I decided to try, not reverting to an older iOS but to a newer, Beta version. I installed iOS 12.0 last night before going to bed and tested all of my apps and phone's functions and so far haven't had a single issue with any of them.

But my battery is back to normal, and only dropped a couple of percentage points overnight while on battery normal mode, instead of low power mode as I had taken to using ever since this battery drainage problem began.

While taking the risk of using a Beta iOS may seem a little drastic for some of us, (and it was new to me), I believe it was worth the trouble of finding out. I made sure that I backed up my phone before installing it however, just in case I had any problems and wanted to revert to my old settings.

If you may be interested in trying an install of the Beta iOS 12.0, it is a very simple procedure, and Apple has all the instructions for you to do so here: Apple Beta Software Program

Hope this helps.

This issue has nothing to do with battery itself. It does not even show under usage percentage. It was caused by the latest 11.4 update. It seems to be the WiFi that keeps searching non-stop until the battery dies completely. Everybody knows it by now and I am sure, just like me, most people have been contacting apple through Feedback - iPhone - Apple though I do not understand their silence...

I leave my 6s phone with a %100 charge on the table and find it turned off after two and a half hours, with a good (%91) battery health. The only solution I have found so far is to just turn off the WiFi and then everything goes back to normal. So, I have no doubt about the reason for the problem; I just don't understand why there is no urgent patch or fix and update released for it.

Does anyone know if there is a fix or release for it yet? Maybe there is and I am not aware?

I would advise you to research some ways of saving your battery or find out which app may be using the most battery life. To check which app may be using the most battery life got to settings and press battery and scroll to where it says Battery Usage and it will give you a full understanding of how much battery you use. Also, try using low power mode to conserve energy. it could be your charger as well. I hope this was helpful for further support please Contact Apple Support Official Apple Support

Have a look at this discussion My iPhone 7 battery draining rapidly particularly at the post by Clickpix, he maintains Updating to 11.4.1 then DownGrading to 11.4 sorted the issue, I still can't understand how it could work but then again this issue doesn't seem to respond to normal fixes ie Restore as New, so who knows.

1. Please tell Apple – Feedback - iPhone - Apple

2. May be you can try to disable 5GHz WiFi and use 2.4 GHz instead, disable Location Services and Background App Refresh

3. Please tell Apple about it – Feedback - iPhone - Apple

I Have this Problem since 11.4. comes out and this is quite a time now.
