iOS 11.4 battery drain

iPhone SE, 1 year old. Used to get 2-3 days of life.

Upgrade to iOs 11.4 (and 11.4.1), and now I get 4-5 hours.

I am on call 24 hours a day and this is seriously impacting my ability to perform my job. Get ready for a lawsuit should damages occur to my company or clients due to a missed page due to a drained battery. A good friend of mine, Dr. T, also experienced extreme phone drain last weekend while on call. Waiting for the first lawsuit...

Would love to downgrade, but Apple is no longer signing any iOs versions.

<tinfoil>Isn't there a product launch coming up?</tinfoil>

In any case, this is the last iPhone I purchase. Tired of not having FM radio, upgrade to brick. etc...

@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.

I have a Blackberry and a few Samsung and Xiaomi phones anywhere from 2 to 10 years old with original batteries. Even on the oldest ones I get more than 24 hours on standby. They all have specific uses. Can you believe my 6 year old 160 MB, 384 MB RAM Samsung Galaxy POP even today gives me 60+ hours on original battery ? It is running Android Gingerbread 2.3

Believe me you won'r regret your decision. As and when actually needed, may be after 3 - 4 years of use, you will be able to get the battery replaced for under 10% of the phone cost. From what I understand the battery charging circuit is totally hardware controlled. OS does not screw around with it. In my case unless I power off the OS my iPad won't even charge !!!

iphone cpu throttling also drain your battery faster. You check the battery if your better cell working below 80 percentage in that case your battery drain faster. Try with another battery whose cell are working 100 %.

@Zide99 -- You're definitely not alone! Vast numbers are experiencing likewise. The problem lies in the software. It's the battery that's taking the hit. While there's a multitude of controls and switches you can turn off, if you're not tech- or iPhone-savvy, then the best and simplest suggestion is to make sure Wi-Fi and Cellular are off when you're not actually using them. Even better is to put phone in Airplane Mode, then switch that off only for phone use.

@boris168 - You can't. When Apple releases a new iOS or updates therein, it offers a very narrow window of time for downgrading before it signs off on previous versions. Even if that weren't the case, iOS v. 11 is a *complete disaster.* It never should've been released and pity the poor soul, like yourself, who's stuck with it. (I am as well but mine was a completely unintentional 11 downloading so I cannot be blamed.) By far the worst iOS software that Apple's ever put upon its customers. The takeaway here is to be aware that the window for reverting to the previous iOS version is super small and plan accordingly.

I agree with you completely. I fortunately am not an Apple fan and am seriously considering surface go for carrying out of town. In my home base I will stick to my desktop as I am doing now and have for the past 27 years.

Hello everybody ... the discussion forum seems to be very quiet. Does anybody got the battery drain problem SOLVED ?? I am sick of waiting for Apple ... 10 testing versions ... and none of them solved the problem. If someone is thinking that Apple is planning to solve the problem with the NEW IOS Version ... forget that.

I have call again Apple on the phone ... and support says that there is nothing that they can do (and again are saying that battery replacement solve our problem). We all know that this is not the problem, a lot of persons have made the battery replacement and the problem persists. What to do more with this stupid/crazy/repugnant situation ??? Any tip ?? Thanks

When I tried to reply, I received "Unauthorized" and figured I was blocked. Tried several times and finally got in.

Everyone is probably just sick and tired from being sick and tired of Apple.

I am just waiting on 12 and staying close to a charger. If 12 doesn't solve the battery drain then I will definitely go Android. If it does help then I will stay with my phone until I absolutely need a new one. At that time I will then decide which way to go.

I can stay unplugged for 1 to 4 hours depending on usage.

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!

Today morning during my travel I switch on some video on my iphone...of course the battery wac 100%. After 1 hour the battery was 45%. So...a p p l e you are very weak company you can't solve this problem in 2018 year. I a p p l e think I will buy a new iphone? No ... never... I will be use my SE till his d e a t h...even I have to charge the phone every hour.

Same situation for me ... new version 12 did not solve the battery drain issue ... as I have already informed before.

I knew that as I was doing tests before version 12 was lunched. We need to do something guys. This is not acceptable.

I am going crazy ... and my battery that had 87% of life ... now goes on 80% after these 2 months charging it several times a day.

As a last chance I loaded IOS 12. It isn't any better and perhaps even worse. Apple has added more battery monitoring features and the "screen on" vs. "screen off" time hasn't changed in days. It doesn't appear to work. My largest drain is "Home and Locked Screen". Could that be draining the battery? When the phone is locked?

Anyway as I stated "last chance".

Apple won the battle on this one. However you have lost my business. I will NEVER buy another Apple product.

They should be ashamed for their lack of support.
