Have you noticed an unusual battery drain on your iPhone or iPad lately? German iOS developer Sebastian Düvel has, and he decided to get to the bottom of it. He used Apple's Instruments OS X app, which allows developers to analyze and test iOS code, and found that Facebook's apps were the root of his battery drain problem.

In short, Düvel discovered that Facebook's apps are not shutting off like they should when they are in the background and not in use. Düvel found that the main Facebook app would become active for about 10 seconds and then go back into a sleep mode before becoming active for another 10 seconds again -- this happens continuously, all day long. The same thing happens with Facebook's Messenger app.
Might be worth shutting down those Facebook apps when you're not using them if true.

this would make sense as to why after the last couple of updates, my phone seems to drain very fast. Guess it's time to start manually shutting this app down!

The wife was complaining about battery drain recently as well. Going to try and just remove her facebook app and see the difference in a week.

But the findings make sense as for a cause.

I believe you just need to ensure you close the app instead of "minimize" it in order to prevent the battery drain. No need to uninstall it.

There could be some truth to this.

I have a jailbroken iphone 5 and with the battery doctor app I have set it to autoclose all apps/background apps when I lock the phone.

I've tested it and sure enough all other apps get closed but facebook is still there when I unlock.

(It's not in the whitelist)

I'm actually thinking this is true. Since tonight I've made it a point to close out the app every time I use it. It's 11:39pm my time and the phone has been unplugged since 9pm or so. I'm currently at 94% where usually I would be in the low 80%s by now. I'm definitely gonna keep trying to test this.

Here's another screen shot of where I'm at now. Unbelievable. All from closing out Facebook and that's it.

I tried it and you're absolutely right... Well, luckily there's a simple solution: turn off the smart whitelist option :) I just e-mailed them asking for some kind of blacklist option to force kill apps in the background even if they're active.

I've noticed now that it does close facebook a little while after locking. Why it isn't instant like others I don't know but it's definitely improved my battery life!

Due to various reasons i have restored and set up as a new phone about 5 times this week. I am doing another as I type this. I will hold off on installing Facebook and see what happens. Will report back.

This has to be true; after I read it a few days ago, I started force quitting the Facebook app whenever I used it and my battery has improved tremendously back to when I got the iP5.

I came to make a new thread about why my battery life's been crap the past week or so. I'm definitely trying this starting immediately.

I'm currently at 8 total hours, 2:35 usage and at 26 percent battery.

FB's messenger app also drains batter like a motherfather
That's noted in the article.

They may change it, but it's intentional at the moment. Not intentionally draining your battery, but it's intentionally not going to sleep when in the background.

Oh wow, this is big news if so. I was wondering why my phone seemed to be draining more quickly than usual! I'll have to give this a shot.

Just delete that piece of crap of an app. It's slow, buggy and stupid. Mobile web version is much much better to use.
