iOS9 background app activity with background app refresh turned off.

Background app refresh controls whether an app can spontaneously launch in background. But it does not prevent an app from responding to a notification in background. You should leave the phone plugged in overnight. This has 3 benefits:

• Your phone will be fully charged when you wake up
• Any apps that do data transfers at night will use WiFi instead of cellular data (WiFi is off when the phone is locked, unless connected to power)
• You can enable automatic iCloud backup, which will back up you phone every night when connected to power and WiFi

There is no downside to leaving it plugged in. You can't overcharge it, because it has a built in smart charger that will stop charging when it reaches 100%.

I did not do a generic copy-paste. I studied your problem and proposed a solution. As you clearly don't like what I posted, you are on your own from here.

Yes! I upgraded my iPhone 5S before going to bed last night. I left the phone plugged in overnight. Got up this morning and used the phone for a few minutes to check emails and such. I constantly close out my apps so that I never have stuff running in the background. All day long I have watched as my battery discharges. It appears to be Facebook. My battery usage screen looks similar to yours. My background refresh is off. Facebook is not open or running in the background. I have been paying attention to the battery drain all day and it is crazy.

I have everything turned off on my phone that would possibly drain the battery. Just in the last 45 minutes my battery went from 100% to 86% without a single app being open. This is not acceptable.

Same issue here, I reported this issue during beta test of iOS9 on facebook app. It happens both on my iPhone 6+ and iPad Air 2

It seems to be an issue with facebook app, as workaround I'm closing the app after using it.

The Facebook app has had a reputation for sucking battery life for quite some time. It seems no sooner do they get it 'fixed' than they release another update to the app that re-introduces the problem.

This is probably an issue you need to take up with Facebook. It's their app, after all.

I think I have found the solution. I noticed Facebook was creating a lot of background usage as well under Battery Settings, even though I have Background App Refresh turned off under the General Settings. I then looked at the Facebook Settings menu (Settings>Facebook>Settings) and noticed the Background App Refresh was turned on but greyed out so I couldn't toggle it. I went back to Battery Settings menu, turned on Background App Refresh and ensured that the Facebook setting was turned off. I then went back into the Facebook Settings menu (Settings>Facebook>Settings) and noticed that the Background App Refresh was now turned off. Then I went back to General Settings and turned off Background App Refresh again, and that seemed to fix the problem.

Hi there Lawrence, I have the same issue as Levy and the others but BOTH my switches are off and yet I show 10.6 hours of background use by Facebook and 68% of my battery usage in the last 24 hours. This morning I turned FB notifications off. I don't "hang out" on FB. I post very little. I share others' images on occasion, maybe 6 a week. Do you know any other tricks to curb FB background usage? I am getting tempted to remove FB from my iphone. Thanks.

Same problem. Background app refresh turned off, but still refreshing in the background.

There has been quite a bit of press lately about the Facebook app doing things it shouldn't, causing extreme battery drain, etc. I'm not surprised.

Hello guys.
I have the same problem except my background battery drain is from APP STORE. The phone was fully charged with Wi-Fi and Cellular DATA - off + minimum screen brightness + all apps closed in the background , when I woke up that was the result I got.. how can it be possible? Even when i dont do anything i just see how my battery life just drains out..

This is one area where iPhone & iOS has a huge mess to sort out with the recent iOS 9.2 update. I have the same problem as you.

There has not yet been a single response showing empathy to the problem - especially from some of those 'level up' alibis working for 'apples' favor forgetting the actual problem faced by the customer.

Problems of a big corporation falling into the hands of economists and finance professionals.

Needless to say, force quit the app and restart the phone - may be that stops background activity
