iOS 11.4 battery = disaster! Handoff is culprit?

This is for Apple:

You are not speaking to Apple here.

Feedback for Apple goes here >>> http://apple.com/feedback

When Apple identifies you are at home, they take the liberty to drain your battery even when the phone is supposed to be DOING NOTHING.

Did you tag your location as "home" in any app? How else would the phone know you are at home?

The only traffic would be wifi and only for apps with background app refresh enabled.

What does settings > battery tell you? What actual processes/apps were using battery?

Small update : I did enable iCloud Messages after the update. I can imagine that needs some processing power but they should give us a warning about it than.

Not sure that's the root cause of my problems though.

Well, it does not take a lot of AI to deduce that the place you are every day between midnight and 6am (or a longer time around that) is home.

iOS will not do that. You explicitly identify your "home". There is no AI that does this.

You can't manufacture a reason to be upset.

Battery health is unrelated to the iOS version. It is about charge cycles and age.

As I restored my iPhone, I lost all battery stats.

Ok, but what about now? You imply your battery life is still impacted. Have you run your phone for at least 24 hours since resetting? Then you have statistics. What do they indicate now?

Hi,

completely the same here.

Mail uses more than 50% overnight, and drains my phone from ~90% to empty, even with all apps closed, bare minimum background updates and location services.

With 11.3 no issues ast all!

And battery condition is stil reported as good.

Need to have this fixed soon, carrying spare batteries and asking for a power socket everywhere is very annoying!

The first step to diagnose battery drain is to go to Settings>Battery to discover which app is causing the problem. With that knowledge, someone here can provide more helpful information.

Also, when updating the iOS, the phone has to re-index the files. Depending on how many there are, this can take 24-48 hours and uses a lot of power.

It's definitely not his battery age.. otherwise he would see more gradual changes not dependent on the iOS version. I just got a brand new SE 3 days ago and updated it to 11.4 my battery health is at 100% and the phone doesn't heat up or anything its just the standby battery drain that's so awful on 11.4 going down a full 50% overnight no matter if i even turn on lower power mode. On my other devices (iPhone 7, and iPad Pro 10.5 its been fine) It seems like the A9 devices like the SE and 6s are getting messed up by 11.4 more info from many users experiencing the same thing here 11.4 - SE - Fast Battery Drain | MacRumors Forums

Hi, I have the same problem related to iOS 11.4 and battery drain, but with an iPhone SE. I contacted Apple Support, they did a remote diagnostics test, they saw that the battery health is OK (84%) -they said thet 80% or less means that the battery is consumed- and they suggested me to change the battery!!

But the iPhone worked well with iOS 11.3.1, with the same usage pattern, the same apps. Apple, please, fix this, and review your quality processes. It seems that iOS versions are not properly checked in iPhones that aren't the latest model.

Strangely, I’m relieved to find I’m not the only one with the battery drain problem. I have an iPad Pro and updated to iOS 11.4 a couple of days ago. I used to use my iPad on and off all day and still have spare juice at the end of the day. Now I see it drop rapidly before my eyes.

I don’t think this is “Home” issue as I’m currently not home.

Nor is it an overnight only issue as I’m seeing the drain all day. When I look at who’s using the most battery power in settings it’s Mail (38%), Facebook (18%) and Safari (13%), so my guess is there’s a problem with anything using the internet. My iPad is WiFi only.

Yes this are good words, i have the same probleme and troubles with my iPhone 8 Plus. Yes ist is totaly unaccepteble. I am filming with my iPhone and i dont want every Hour to Plug in my powerbank.

Please Apple Signe the iOS 11.3. for downgrade.

Sorry my Bad english

Yesterday I “fixed” the problem of battery drain in iOS 11.4 quitting a lot of funcionalities. I tested with:

Wifi: Off (From the settings, no from the control center because control center don’t turn off WiFi)

Bluetooth: Off (also from the settings)

Location Services: Off (Privacy / Location)

Handoff: Off

Background App Refresh: Off

My hypothesis is this problem is related to WiFi-Bluetooth chip that usually is the same chip.

Apple, fix this disastrous update

Hi

Turn screen brightness down a bit go to settings down to apps refresh turn this off.

That will save the battery.

Wait for ios 12
