iOS 11.4 battery drain

There is no luck after with new battery replacement as the battery drains same way. in addition to this now a new problem cropped up, phone is in headphone mode without even using a headphone..tried all the possible fixes shown on the internet but not successful, really feel like disgusting at the moment as final suggestion is to visit a apple service store once again. Apple what the **** is happening with your phones !!

Solution is there and quite obvious but Apple will not resort to it. I have a feeling they are always in God mode - We don't make any mistakes - EVER !!!

Just reissue the earlier working version renumbering it as 12.0.0 .

Still the same problem with battery drain after 11.4 and 11.4.1. As always charged all night and was 100% this morning. After 1 hour (I didn't plug in after moving the phone) it is at 55%. I also didn't put in Low Battery Mode. Battery Health is at 87%.

Apple: Is this supposed to be acceptable? How would you like a 6S if it performed like this?

I keep hoping for a fix and can still use it as I have a charger located everywhere, cars, basement, living room, bedroom, etc. If I get to a point where I absolutely need a wireless phone I will NOT buy another Apple product. iPad mini and wife's phone with never be updated again.

I did pay to them for the battery replacement INR2000. Now battery health shows 100% but it drains as it is. I spoke to a friend who got his battery replaced recently on his 6 and while replacing the battery apple service guys take a confirmation from us that they are not responsible if something goes wrong while changing to new battery, so thats it while changing they messed up with the speaker it seems. No I am really not thinking to go to apple authorise service guys anymore instead i will go to a local super boy who repair any phone in the world just like that and get it fixed of the problem with spending few bucks.

Yesterday I plugged in my 10y old plugin earphones (instead of the brand new BT ones). I switched to airplane mode and made sure realy all is plugged of. I started amazon music app while cycling for 5h. Surprised to see my battery was still at 96%.

On another day with BT it was empty after 45minutes 😂.

As Genius bar wanted to see money for battery replacement even I have in the chat protocol its for free, I am not to spent more money. Knowing the battery is not the root cause. However standard procedure — replacement of battery.

@marcinfrombydgoszcz - laughing & crying at same time. Here's what I do to preserve some battery power through a day after accidental install of iOS 11.4.1:

1. Airplane Mode: On

2. Wi-Fi: Off

3. Cellular: Off

4. Low Power Mode: On

Then only when I must check for emails, texts or go online via provider or Wi-Fi do I switch on the appropriate slider. So I'm on and off controls all day. A giant PITA. But the only method to still have a little battery juice by day's end. Be it via car charger, outlet or power pack, I also charge every chance I get through the day.

My phone's just a year old. Was running great on iOS 10.3.3. Then 11 came along. Battery drainage was immediate and extraordinary. This diehard Apple loyalist for 25 years is looking to jump ship. So sad.

@Zide99 - To your question, no, nothing got turned on with iOS 11.4. It's a software issue. The battery's taking the hit. Rest assured that your experience is most common. I'm iPhone-savvy, have tweaked and/or turned off every conceivable setting, still suffered incredible drain and in the 11th hour can only share what works, kinda sorta as a Band-Aid solution:

1. Airplane Mode: On

2. Wi-Fi: Off

3. Cellular: Off

4. Low Power: On

You read right. These turn off phone functionalites BUT slows the excessive battery drain. Only when I want or need to use the phone do I switch on the appropriate function. Then, task completed, off it goes. This mode of battery "preservation" is one giant PITA, yes.

A lesser-PITA alternative is to set the settings as above EXCEPT keep Airplane Mode: Off. One less function to switch on and off through the day.

Also to stem excessive drainage, I use every power source available through the day -- car charger, outlet, power pack. Some 25 years I've been with Apple and never seen anything as insulting and disregarding to its customers as iOS 11. Truly. My phone's only a year old and I'm already looking outside for a replacement. Sad.

@kaceel - In addition to disabling Wi-Fi, I've disabled every function, including Cellular and, of course, Location Services; Low Power Mode also always on. I also keep the phone on Airplane Mode, the biggest "disabler" of all, until I need to check texts, emails or go online -- and only then do I turn on ONLY the relevant function before again disabling it. Basically by disabling the entire phone, battery drain is slowed, but not eliminated.

@kaceel - Precisely. Yet what good is a phone that's fast rendered useless due to excessive battery drain? My approach, at least, enables functionality (albeit highly-measured) through the day; the second option does not. Which is the lesser poison? Again, none of these problems existed pre-iOS 11.4.1. There's a definite segment of iOS 11-iPhone users who depend on their iphones for work and are jumping ship for the dramatic drain. I feel their pain and do not blame them.

@jonfromwhitefish - Ditto. iPhone SE, 1 year old, got 2-3 days of life on 10.3.3. With 11.4.1., now a day but only with radical down-powering, i.e., Low Power Mode always on, Airplane Mode on and switched off only to use phone, then back on it goes. Like you, I too am planning no more iPhone purchases. What good's a phone that demands a constant power source (i.e., car charger, outlet, power pack) or radical down-powering to maintain some semblance of power through a day? Will be interesting to see what happens to Apple's stock in coming months after this debacle.

After Apple updates bricked my early devices years ago with bogus software for which there was no fix - I never update until forced to. I research the problems of every update for 6 months before deciding if its worthy or not. My 6s is running fine on iOS 10 and its going to stay right there - I need a phone and could care less about an updates new bells and whistles. If it's not broke, don't fix it. Why do folks trust their device to Apple updates and live with frustration time and time again? Not worth the risk.

Hi all !!

I have replaced the battery of my 6s yesterday in a Apple Service Store ... and the problem persists.

Before upgrading to 11.4 ... I had almost 1 and half day with battery ... and after upgrade I was getting 5 hours maximum.

After all tests and all efforts done I have accepted to replace battery as a last chance and to prove to apple support that the problem was not in the battery ... but in the operating system. After battery replacement yesterday ... I get 8 to 9 hours of availability. This is a crazy situation. And I don't understand how they can't see that when they replace the battery ... phone was there for around 5 hours ... they should see the battery draining while the phone was there (and it was very hot when I got it from them). Don't replace the battery, don't spend $29€ on it ... as the problem is not there.

This is a very bad and sad situation with Apple !!!!

That’s too bad. Well hang in there. I guess I was lucky to be able to downgrade a few days ago. I also tried the beta update 11.4.1. that however didn’t solve the issue either.

iPhone 6S (85% battery life according to Battery in settings).. I will try to connect to 2.4GHz wifi instead of 5GHz and see..

It’s the same in the 12 beta as well sadly. Was down to 2% this morning. Looks to be related to background refresh and app usage in the new OS. The only way to fix it is revert back to 11.3.1
