iOS 11.4 battery drain

yeah this IOS 11.4 is the worst to be honest I thought maybe my 6s battery is scraped so I changed it as well still it drains like anything. the worst update ever and also sometimes it makes my phone hotter.

Since upgrading to iOS 11.4 I am getting about 2.5 hours usage between full charges. I have tried power off/on of the phone and disabling the iCloud "handoff" feature as well as "background app refresh" but battery life has not improved.

Have 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,Reset, Reset Network Settings, try resetting your network settings.

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 can, also, negatively 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!

Hi!

I have a theory about this and here are my observations with an iPX;

Prior to 11.4

* Wifi disconnects during device sleep/standby (both @ home 2.4/5 and @ work)

* Emails aren't fetched during sleep/standby for the built in email client - a manual refresh fetches them though

Post 11.4

* Wifi is now active during device sleep/standby - kind of how I remember it was in the earlier days with iPhone

* Emails are now fetched automatically (which I expected it to be normal behaviour)

I'm not sure what to make of these observations though, the change in Wifi sleep behaviour could affect certain AP/Wifi configurations I guess. With more background processes going active when Wifi always active might also affect certain applications like mail clients during night time..

This thread is about the Wifi going inactive;

https://discussions.apple.com/thread/8188526

Just my thoughts in a complex issue.

Kind regards,

Per

I was looking at the NEW inclusions in IOS 11.4 and one of them is iCloud Messages!

iCloud now stores EVERY message in the cloud so I guess for people that message a lot, that every message on your phone is now being uploaded to iCloud!

Read this article from Apple: Keep all your messages in iCloud - Apple Support

I turned off everything in iCloud settings except for find my phone, I left Bluetooth and Wifi enabled and charged my phone to 100%. This morning my phone was at 99%!

So, is iCloud messages the elephant in the room, flattening batteries everywhere by uploading all messages and images in the messages to iCloud?

I’ve had luck only using 2.4 ghz network yesterday. Reset Network Settings has worked so far on one device that is now connected to 5 ghz WiFi.

It will rename your device. So. Be sure that if you have it named “**** iPhone” after a network reset it will then just be “iPhone”. The Apple geniuses didn’t believe me. I showed them it was true.

Try it.

me pasa lo mismo. Desde que actualice mi iphone 6s a 11.4, la bateria dura medio dia..

Es un desastre. Soy usuario de iphone desde hace años, es la primera vez que me pasa esto.

ARREGLEN LO POR FAVOR

the same happens to me. Since I updated my iphone 6s to 11.4, the battery lasts half a day .. It is a disaster. I'm an iphone user for years, it's the first time this happens to me. FIX IT PLEASE

dude relax this is neither your concern nor it should be I posted cause I wanted to know whats going on with iOS 11.4 and you're taking it way to serious, I changed my battery from a local store though it says apple and got a guarantee and warranty for it!

now can you breath? or still go for a nag? seriously dude!!!!!

Seriously dude, Apple do not sell parts, so you should get your warranty,

and stop ranting about your battery.

My iPhone 5s, 6, 6s, 6s Plus, 7 and 8 Plus as well as iPad Air 2 and iPad Pro 12.9" all on iOS 11.4 and are running fine.

I and millions others must be the lucky one.

Yes. I have new batteries in both iphone6 phones and installed iOS 11.4 in both yesterday plus my iPad. Today we are noticing a significant change in battery usage. Possibly 50% decrease in battery life with minimal phone usage.

The battery life was great prior to the iOS 11.4 update. Terrible update.

I have same problem on iPhone 7 plus.

Biggest drain on battery in 24 hours was Safari, even though I hardly used it.

Also it's taking forever to recharge the phone - much slower charging than used to be.

I just stumbled on this thread after googling "iOS 11.4 and battery drain". I also have had bad battery life after updating to iOS 11.4 on my iPhone X. I used to get 8 hours plus of usage time a day and now closer to 6 hours with the same type of usage. I can only assume that it is the new update causing this battery drain based on the replies in this thread and some articles online that have popped up regarding this topic in the past couple days. I hope Apple sends out an update fixing this issue ASAP.

In my case it is not "a little" faster 😟

With all the apps shut down, no wifi or bluetooth (both switched off) my iPhone only idles for 6 hours and then battery is dead.

Can't stand it. Get your act togheter Apple!

Yep, and it’s not just iPhone. My iPad battery has been killed, too. It loses 40% overnight, with the cover closed all night. And it drains completely - I need to plug it in for 10 minutes before it’ll even start up again. Can’t wait for the fix.

My iphone 6s battery was a tank until the day I upgraded to ios 11.4. The battery now depletes in few hours. It appears to be dependent on wifi, as the battery does fine if wifi is off. Very frustrating!! I hope a fix comes soon.
