I've noticed that many apps don't close when clicking the back button, they only stay open in the background such as the official facebook app, battery saver...

I noticed that too. Not the battery saver app, just the facebook app. Every time too. It's annoying. Not only that, but I never get FB notifications anymore.

its not supposed to close it anymore i think, back button only "suspends" wp8.1 apps..
that what i remember they said at /build, i may be wrong

I remember the same, it is supposed to reduce the resuming screen and improve multitasking. So the back button only suspends the big apps now.

Yes and there is noting wrong with it, ao don't start and close apps every time in the muktitask window! Just leave it! Battery is fine...

It seems that the back button does still close some apps, as well as tabs in IE. It's actually pretty handy in IE! I can open a link to an article or whatever in a new tab, and then just back out of the tab when I'm done reading to close the window. If this wasn't deliberate behavior, I sincerely hope they don't "fix" it... Especially since some sites still don't play nice with the WP browser when returning from the article to the archive.

This change in behavior is intentional by Microsoft.

New apps written for 8.1 aren't supposed to close when the back key is pressed from the first page of the app. OId apps still do, but they can be updated to remain 8.0 apps with the new behavior. Old apps that haven't been updated will still follow the old "quit on back" behavior.

The idea behind the change it to let the OS more fully manage memory. With the new behavior, when a user "re-launches" a suspected app, the OS can just move it to the screen since it's already in memory. If the user used lots of other apps before re-launching one, the OS may have actually unloaded the app from memory (to use the memory for one of the other apps) so the OS really does have to do a full app launch.

Users don't have to worry about apps sucking up battery life because WP doesn't give CPU to suspended apps. Users don't have to worry about keeping memory free for the next app to be launched because WP manages that automatically. If an app truly hangs, users can "kill" it from the task switching view (long-press the back key and tap the "X" button or drag the app downward).

Go to the battery saver , and you can see that some apps allowed to run in the background, these apps when you open it and press the back button they don't close.

A bit wrong. You don't have yo open them, they will run I background. For example whatsapp. I restart mu phone, whatsapp is running already...

That's correct! So everybody who wants to close apps is just wrong. And if its a "habit", change it, its useless!!
