#37283 — like hibernating or like shutting down a PC?

Is turning off the phone like hibernating or like shutting down a PC? 

It's hard to keep  track but it seems like there are apps running
whenever I turn the phone on that I didn't start in that session. 

Are these the very same apps that were running when I turned the phone
off? 

Tnx.

Powering off the smartphone is the same as for any computer.  It's off.

Services.  Same as you've encountered in Windows.  Auto-startup
programs.  Same as you've encountered in Windows.

You would have to check yourself.  Settings -> Application Manager,
scroll over to the Running column.  Compare before powering off and
after powering on.

Unlike Windows where closing a window by exiting the problem has the
problem stop and unload from system memory, Android leaves apps running
until more space is needed for a newly active app.  The old idle app
gets stopped to make room for the new active app.  For Android, it is
the job of the OS to stop and unload old idle apps, not of the user.

You could use the Running column mentioned above to stop any still
running apps (that you think you exited) but be careful which ones you
try to stop.  Also, services may be configured to always run which means
you kill them but they reappear.  That's why some app managers that try
to unload  the old idle apps don't work as advertized because they
cannot prevent the auto-load services from loading again.  There are
several app manager or battery saver apps but you'll find them of
varying usefulness.  You can try using a startup manager app but, again,
it will not affect services or, if it does, could render many features
unusable since those services may not load when needed.

I should have done what follows before I posted, but I guess I was
afraid I'd forget the whole thing until I was away from the phone. 

I was just running the phone and I tapped the square that shows what is
running, foreground stuff, not background, and there was Opera,
Settings, Duo**, Messages, Hangouts**, and ChangeMyMac***

Then I rebooted the phone, tapped the square, and all 6 were still
running!  And only those 6.   From what you say below about memory
management, I guess that doesn't hurt anything, but you know, because of
PCs, I'm used to the opposite.  This is a Blu phone.   I gather other
phones don't work this way. 

Also, at the bottom of the screen after I tap the square is a blue
broom, which appears to close everything at one time.  

Thanks for the link at the bottom. I've read part of it and I'll finish
it after I go to sleep. 

**Neither actually running yet, but the starting screen was showing. 
***I haven't rooted so it won't work, but I tapped it by accident in the
previous session.

Pressing 'square' doesn't show things that necessarily are *still* 
running, just that those have recently been running, and can be 
restarted where they left off by selecting them from that list

Aha.  I assumed otherwise.   This changes everything.

More likely you tapped the Recent button to show a list of your recently
used apps.  Like a MRU (most recently used) list in Windows, you can
clear it out.  That only clears THAT list.  It does NOT unload any apps.

It's a MRU list.  Not a task manager showing active apps.

You are asking in an Android newsgroup.  Android memory management works
the same way on all Android phones.  I don't know how iOS or other
mobile operating systems work (don't have those so haven't bothered to
investigate their memory management scheme).

Any smartphone vendor can customize the OS and screens however they
want.  That is how they differentiate themselves.  If they all used the
plain vanilla OS without any tweaks, they would all be the same phone so
the only factor in choosing one over another would be the hardware
(memory size, SD card capacity, speed, processor(s), camera features,
etc).  I don't have a Blu smartphone to know what they decided to shove
into their GUI.

To find out about how Blu customized their version of the Android OS and
what apps they pre-installed, read the smartphone's manual.  

http://bluproducts.com/android-phones/
http://s536785483.onlinehome.us/user-manuals/

You did not mention you series and model so I cannot go read the online
manual to see what the broom icon does.  My guess is you tapped the
button to show the Recent list and at the bottom is a button to clear
that list.  On my Samsung Galaxy Core Prime smartphone, that icon shows
as 3 horizontal bars (representing lines in a list) with an "X"
character, meaning that will x-out (clear) the MRU list.

After a power up, the MRU should be empty until you actually run an app.
Not even background services that auto-load will show up there.  It is
an MRU of the apps that *you* loaded or re-accessed.  That's why I
suspect you only locked the smartphone instead of actually powering it
down since the MRU still has the same entries in it.

How do you power down your smartphone?  Do you press and HOLD the Power
button until you see a prompt asking if you want to power down followed
by another safety prompt to ensure you really do want to power down?
When it is powering down, does it vibrate just before the screen goes
blank to let you know, yep, the OS unloaded and the hardware will
immediately power off?  That's what my Samsung does.  I don't know what
your Blu phone does but it should be similar.  Just tapping the Power
button merely locks the smartphone, not power it off.  A long-press is
needed on the Power button to power it off.

My Samsung's variant of the Android OS clears the MRU (Recent) list on
power down or, probably more accurately, begins with an empty MRU on
startup.  Your Blu variant of Android might somehow retain the MRU list
across phone sessions; i.e., the MRU survives a power cycle.  That means
they would have to write it somewhere that survives a power cycle rather
than just retain it in memory.  Seems a waste to show an MRU for a newly
powered up smartphone before the user has had a chance to run anything
yet in the new phone session.

Aha!  That makes all the difference.

I get it now.   I'm glad to hear this.  I like the idea that not much is
running after I boot the phone, even if the running tasks don't
intervfere with ones I want to load.  Call me obsessive compulsive, or
something.

By other phones I meant non-Blu Android phones.   I know Android is
suppsed to be Android but don't forget, I was still sure the programs
were all running.

I doubt if it is in the manual, which is pretty brief.  I'm pretty sure
I read the whole thing and the broom was not mentioned, along with mnay
other things not mentioned.  When I bought the phone, new, in  the
retail box, there wasn't even a reference to the online manual.   That's
what happens when you go cheap.  

I should probably read the manual of some other maker's phone.  It might
have small differences but it would go into a lot more detail.

Yes I think so.

No, no.  I know the difference.

Yes.

Not sure if it vibrates, but otherwise yes.   I checked. It does n't
vibrate but it plays about 3 notes, and displays the same graphics as
when I turn it on.  But more important, since I tap Power Off, I'm
pretty sure it's power off.  :-)

Well it doesn't show it until I tap the square.   But I think I like
that I'll be able to start where I left off on all these things.

What do you mean by "off"?

- a light press of the power button (or just leaving it alone for ~30 
seconds) so the screen turns off, but it will still ring, and you can 
wake it up immediately with another press of the power button

- a long press on the power button so it gives a menu with one or more 
power off/restart options? and will then take a minute or two to boot up 
when you turn it on again

Android apps are designed to save their state and return to where they 
left off, even if they have stopped and restarted since you last used them.

I'm glad I noticed this.  Thanks.
