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!

Background refreshing I always have had off. With Location services is I never had a problem until ios 11.4 update. With it turned off it may get better standby battery life, however, when using the device makes no difference in battery life. Another thing about having this turned off is I use location services for some apps so having it off, again, puts me at a inconvenience which I think is unacceptable to have a smart phone that can’t be a true smart phone, especially, when paying a premium price tag. Without a doubt the biggest problem with having the location services turned off is in the event your phone is lost or stolen you will not be able to locate it using the “find my iPhone app.” At this point I might as well have a flip phone.

Just bought my 6s three days ago and upgraded to IOS 11.4 a few days ago. Big mistake - my fully charged batt was down to 50% this morning even though I disabled backgound app refresh and some unecessary location services, per some suggestions posted here. I’ll try disabling ALL location services tonight and see how that goes. That means no navigation and other useful services, which is a drag!

Thanks for mentioning WIFI - I think you’re onto something. My batt life us much better not logged in, and I’ll test it later tonight - charge the batt and lturn wifi off for the night. It’s funny how my 4 year old 5c barely drained overnight unlike the brand new 6s I bought three days ago. Must have been due to Apple’s generous performance throttling of my old phone, I guess.

I have the same problem with an iPhone 7 on iOS 11.4. But, yesterday I updated to iOS 11.4.1 and something change a little. On rest mode it doesn´t appear to drain a lot like 11.4 version. On a normal day I think its draining a little less too (not exactly confirmed on 1 day). The problem is that when I entered Low Power Mode, and I was updating some apps...battery drains from 20% to 5% in a few minutos (maybe 10 minutes or a little more). Hope this was only my imagination or something on the first day of updated (sorry my poor english).

Hi. My iPhone 7 Plus normally last for 1.5 days before updating to iOS 11.4. Since the first day I use iPhone 7 Plus, I have off a lot of functions such as Dynamic Backgrounds, Automatically Upload Photos to iCloud, seldom on Wi-Fi, Personal Hotspot, Bluetooth, and never activated Handoff function, etc, etc.


Excessive battery drain since installing iOS 11.4, the device's battery lasts less than a day. The battery health is 93%. Rebooting my affected iPhone does not resolve the issue. Battery drain problems, particularly in standby – use around 6% to 7% even my iPhone left untouched.


The battery drain problems have not been addressed in iOS 11.4.1. My device’s battery can last for around 1 day if off the 4G function. One way to resolve the battery drain problem – on the Airplane Mode function. However, Airplane Mode turn my iPhone 7 Plus into an idiot phone (still an iPhone, anyway).


Sincerely, I don’t care about USB Restricted Mode which include in iOS 11.4.1. Can Apple do something to address the battery problem instead of those update which I feel totally meaningless.


Most frustrating - Apple never acknowledges the battery drain problem which troubles me every single day after installing iOS 11.4.

such as not using certain WiFi’s, making sure all my apps are always turned off, etc, as a solution rather a bandaid for the problem. Whether they are doing it or not apple should take responsibility and fix this problem in a timely manner instead of letting their customers suffer. I recently went out of the country, came back, and had this problem. My mother who was here in the states with the same phone (iPhone 6s) also had the same drained issue. I talked to Verizon they said it was my phone. So I went to Apple then they said it was my battery and the problem was Verizon’s new cell tower firmware, in all fairness it did need to be replaced, however after it only marginally fixed the problem. My mother who rarely uses her phone couldn’t leave her phone on standby for more then 2 hours without almost completely dying. I couldn’t even be on the phone 10 minutes without it almost completely dieing. Went to Apple the said battery was fine on her phone and said she had to many things running, what?! Ok I’m sorry if news, email, WiFi, Bluetooth, txt, call or too many things running in the background for the battery to handle, however, never had this issue before iOS 11.4. So I did some research I heard some people had better luck on iOS 12 beta. Installed it on my phone again only marginally better. At least now my phone won’t die within 2 hours on standby, but when I’m using it still ***** the life out of my battery just as quick as iOS 11.4 and it doesn’t matter if WiFi is on or not or on 5g or 2.4. At this point Apple is garbage, has been since jobs died, to me the only fix is waiting for the new phones to come out and get the pixel 3. Googles where it’s at now. Apple is not transparent every where you go they point the finger at the other guy with no real answers. I’m not going to waste my time making sure everything is in a particular mode to make sure my battery can last 3 hours ?!?! Screw that goodbye Apple. I’m tired of waiting for the next update to solve the last updates problems, apples just a revolving door of problems.

Devices updating to iOS 11.3 will initially have performance management disabled; it will be reenabled if the device subsequently experiences an unexpected shutdown.)

All iPhone models include fundamental performance management to ensure that the battery and overall system operates as designed and internal components are protected. This includes behavior in hot or cold temperatures, as well as internal voltage management. This type of performance management is required for safety and expected function, and cannot be turned off.

Hey Guys. My battery report shows Whatsapp use most of battery. I am trying not to use Whatsapp today (this is difficult and many cannot reach me today). See is there any help. Whatsapp running at the background even I have off background activities. I am going to restrict Whatsapp to use my data. Let me know if you have same battery report. Thanks. By the way, I have updated iOS 11.4.1 using WiFi in the setting. Seldom use iTune.

Apple you need to fix this. I have an Iphone 6. 11.4.1 did NOT fix the problem. Having to turn OFF Location services is not a solution. Come clean and admit there is a problem. I love Apple products but you can't hide when there is an issue. It all started with the 11.4 update. Let me go back to 11.3 at a minimum until,you solve the problem. My phone is useless unless it is plugged into wall. My battery capacity always shows 93%max capacity. It will drop before my eyes from 80% down to 20 in a matter of 10 minutes just reading my email. This is on you. The battery is not the problem.

Thank you for taking my comment as intended.


I am extremely frustrated with Apple and their 11.4 and 11.4.1 IOS.

I too have noted that if I don't use then the battery might last long enough to make an emergency call if needed.


My wife's iPhone 6 is on 11.2.1 where is will remain. It is seldom being charged and the battery holds it charge. It does NOT have the Battery Health (Beta) and I wonder if that might be the cause of the drain since it is constantly monitoring the battery capacity. I wish I could delete this Battery Health (Beta) and it was included with 11.4 and continued with 11.4.1.


Apple really has done a great disservice to their customers by remaining quite and thought they were better than this.


Apple: Please confess, provide a solution, and provide a timeline so we can patiently wait.

Your silence is detrimental to your ability to retain your customers.

When I updated unwittingly from 10.3.3 to 11.4 my phone needed to be charged at least 3 times in 24 hours! With the 11.4.1 I need to charge it about 2 times. Before any11.4 updates I needed it to be charged only 1 time! I am using a an iPhone 6s 32gb. So IMO 11.4.1 is slightly better than 11.4 but not anywhere close to 10.3.3! Apple, you need to fix these and rest assured I won't be updating (knowingly) to ANY major future updates EVER! Every time I upgrade, either the battery life is shot or my CarPlay stops syncing! I DREAD THE UPDATES! I WISH I COULD TURN THEM OFF FOREVER!
