#35026 — SIM card in or out? Battery life?

I have a Samsung Galaxy Note 2 SCH-i605.
No service.
Should I take out the SIM card?

I leave it in Airplane mode, but is that sufficient
to minimize the power consumption of the radio?
I can still initiate a call, although it only gets me
to the "no service" message, so some part of the radio
is still enabled.

Would removing the SIM card help battery life?   Or maybe increase
consumption continually looking for a SIM card?

Are there techniques for neutering the phone radio(s) completely
without rooting?

Longest standby battery life is the objective.
I do not need any emergency anything.  Just want it to have
some battery life when I decide to use it on wifi.

I don't think so.

It might stop the phone from trying to register.

Notice that with the SIM removed the phone should still be able to make
emergency calls.


WiFi is the thing that uses most battery. If you can configure the thing
to switch off the WiFi when the screen is off, it will last more. My
Asus tablet (with SIM removed) goes from two days to a week in this mode.

definitely not. the gps uses the most (when enabled), followed by the
cpu/gpu and display.

not by much.

that has more to do with the cellular radio being off than wifi.

Yes, GPS uses a lot if constantly queried. But the display in standby
uses nothing, whereas the wifi does, unless configured to switch off
automatically.

From lasting 2 days my tablet goes to last 5 days minimum. A lot, double
or triple.

No, the gadget that displays power by application differentiates both,
and WiFi goes to 20% battery.

the display in standby is off, so obviously it won't use much.

it does switch off automatically.

that's not because you turned of wifi.

it's because you turned off *cellular*.

No, this is configurable. For instance, you may want to be notified the
instant an email comes: this need the wifi to be up even if the thing is
in standby. It may be continuously or at intervals.

No. There is no cellular and I did not touch it. I touched the wifi
config to be off in standby, and the documentation of the tablet
documents this action and the power saving result.

when the phone is sleeping, wifi is off, powering on every once in a
while to check for mail or updates or whatever. when the phone is on,
wifi is also on and using very little of the overall power draw, the
bulk being the display and processor.

if you have a sim, there is cellular.

Again, this is configurable and depends on circumstances. There is a
graphic that depict how much power was used by each major application,
and WiFi is typically large. It can show a solid bar or broken, showing
when it was on.

On my tablet, WiFi shows 8% of battery power used, and operating system
24%. Display is 2%. It predicts that it will last 4 days more, and last
charge was two days ago.


On my tablet, power settings, I can tell the WiFi to never power up
automatically when the device is on standby. Another setting is to leave
on automatic, to power up as needed. I have more settings than you.

No SIM.

thanks for proving my point. 

8% is not significant and not worth worrying about. meanwhile, the bulk
of usage is the os (i.e., the cpu), at 24%.

since display is 2%, your device is sleeping most of the time.

Sigh. The same device, with the wifi in automatics mode, uses a lot more
battery, and lasts 2 or 3 days, not six. You are seeing only 8% because
it is DISABLED, not "Automatic". My point, not yours.

That gets to the root of the question...
I believe you have standby radio communication whether you have
service or not.  The SIM and some $$$ gets you the ability to
use the device on the web or phone system.
The key question is, "Does any SIM/noSIM/Airplane mode save power?"

What's the difference in STANDBY power consumption between
1) a SIM with no service
2) no SIM
3) airplane mode with SIM
4) airplane mode with no SIM
5) SIM WITH service
6) SIM WITH service, but out of tower range.
7) SIM with no service, but out of tower range.

Does the system keep retrying updates despite the fact that
there is no cellular connection?

I want the cellular radio to STFU to the greatest
extent possible without powering the whole phone completely off.

then turn it off. the easiest way is enable airplane mode, which shuts
off all radios, then turn wifi back on.

then ask yourself why you bought a phone and want the phone
functionality off.

No, the easiest way, on most handsets, is to turn off cellular data. 
This can then be left off (unless and until it's needed) without 
affecting the setting of WiFi or Bluetooth, or what's turned on and off 
by the curiously-named "airplane mode".

no, because the cellular radio is still on and using battery, which is
not what he wants.

So, you're saying that in airplane mode, SIM in or out has no effect
on power consumption???

It was in the FREE box at a garage sale, so I graciously

airplane mode turns off all radios, so it doesn't matter what you put
in or take out of the sim slot. the cellular radio is *off*.

now ask yourself why it was being given away for free.

I don't understand what you are intending to communicate!
Asking oneself what someone else intended is an exercise in futility.
I'm not asking myself anything.  It does what I want.
If you're trying to make a statement, it would be best if you just
made the statement that expresses your superiority and moved on!

If your phone is rooted, the paid version of LeanDroid allows you to
turn off the cellular radio exclusively, and to optionally schedule
the on/off time.

Hardest part of turning off/on cellular data on Moto's Droid X2 is
remembering to find that setting not under *Wireless & networks* but under
*Battery & data manager*.
