Hi,
You may already know this tip but since I did some tests and measurements I thought that it's a good idea to share it.
I found that if you have the Airplane mode (flight mode) always on then A500 consumes about 8% less battery. Right now I am not in position to publish more details about why this is happening, since I am still researching it, but it works. It has to do with an application that periodically checks for 3G signal (Yes in A500).
Now most of you will think that WiFi or Bluetooth don't work with flight mode on. This is not true, they work as expected.
I have developed a free widget named TaToggles which is very helpful if you want to toggle WiFi, Bluetooth, Airplane etc. Read more about it here http://www.chdcomputers.gr/en/mnu-applications-en/mnu-applications-android-en/mnu-app-android-tatoggles-en
Hope this is useful to someone...
Thank you,
Christos
Thanks for the tip, I'll give it a try. Though, I hope that Bluetooth works , since it doesn't works while I'm on airplane mode on my Xperia.
This is an old tip, already discussed like a year ago here. I personally just use Acer Iconia Battery Saver on Android Market ( https://market.android.com/details?...RlcnBoYXplLkFjZXJJY29uaWFQaG9uZURpc2FibGVyIl0. ) to disable the 3G service altogether, no need to mess with airplane mode or manually toggling services on or off.
Same effect can be achieved by inserting "ro.carrier=wifi-only" (without quotes) into build.prop, which one can find at /system.
With best regards, maris

Yes. It's one of the benefits of his ROMs.
After installing / applying widget, pages took a long time to load and scrolling was 'jerky' (Firefox mobile).
Uninstalled and everything was back to how it was beforehand.

You mean TaToggles widget? If so, could you please tell me if the problem was only in Firefox Mobile or elsewhere?
Please let me know in order to investigate the problem.

WiFi and Bluetooth work when flight mode is on???

In Samsung Galaxy Tab 10.1 and A500 yes they do. I don't know why this is happening but I suspect that it is because flight mode turns off the 3G radio and not all the radio. I am researching it and when I 'll have more I 'll post.
Note: If you have enabled wifi while you are enabling flight mode then it turns the wifi off but you can enabled it again without disabling the flight mode...

Yes. When you first turn airplane mode on, it shuts down all connections. Just toggle wifi, or Bluetooth back on, and it will stay in airplane mode. As a previous poster mentioned, it's old news, but apparently not old to everyone?

I got a new Samsung Galaxy Tab from Verizon, and I will be out of the United States for a very long time, I am going to Mexico, so I don't think I will have signal over there and my galaxy tab will keep searching for a mobile signal, and that means that my battery will finish really fast, because it will keep searching and searching and searching. I was wondering how I would be able to disable the search of the signal so I don't run out of battery really fast.
Thanks in advance!
Hold the power button down which brings up a menu to deactivate "data network mode"
Already did, and it stills keep searching for a mobile signal :S
try
settings
Wireless and network
mobile networks
uncheck all
Switch on airplane mode. then enable wireless networking. no signal hunt.
there is also a radio disable mode from phone pad *#*#4636#*#* I think. then turn off radio. same result as airplane mode with wireless switched on so first one easier.
hope that helps.
Here is a Summary of what I've been doing to try to disable the mobile signal, but not success, also here are some pictures of what is happening so you can understand me better. Here are the pics and captions: iamunicorn.com/GalaxyTab
Thanks in advance!
read my earlier post - switch on airplane mode, then enable wireless networking!!!
or alternatively, try searching the forum - its been addressed before.

How is it not the best way if it's the only way to do it? Really, it's a toggle switch, get a widget. How can it be any easier? That's like saying the volume rocker isn't the best way of changing the system sound.

What I meant is that there should be a Disable button, like any other cellphone... but thanks anyways I will use it like that for now.
are you kidding?

Of course you will have signal. It is not like you are going to Venezuela or something......... however roaming charges will apply
U$800 for a UMTS galaxy tab? f**k no!

figured it out
The Tab is just a cellphone I think, so an dedicated button to "disable" the signal is not a really good thing for samsung design team.

I found this while searching on google. I take no credit for this, but am posting it here so that you can use it too.
Basically it enables airplane mode and disables it at boot. It doesn't add any time to boot, because it coincides with the Media Scanning.
All you do is install it and forget about it.
Anyway, heres the link:

I actually had this installed for a couple weeks now. Phone boots and then goes into airplane mode. I did love the one time where my phone booted up, I got a phone call right and forgot about the airplane mode and it kicked me off the call!
It won't download to my phone and I'm stuck at work. Can anybody upload it here or post a drop box link for me? Thanks!
Edit: Forgot I can use Astro for the download.
Mike, what do you think of this explanation and fix? It is interesting to read there why this happens, if nothing else. I look forward to your ROM fix tonight!
I actually have 2 tasker events setup that takes care of this nearly transparently. On device shutdown tasker sets airplane mode and clears it on boot.
I just have to do it manually if I get some kind of random reboot or sleep/charge death.

ok and what is your percentage ?
I only realized this was an issue sometime last week and when I checked it was 50%.
Toggle airplane mode and within 10 mins it dropped to 38% and then went down to 17% a few hours later. But since then everytime I unplug or reboot I toggle airplane mode and most days it's at 0% ~ 5%

If I catch it right away it will go down to 0 by days end. If not and I catch it later it varies.
thanks for the link! i'm just curious though, is there any reason why this signal bug hasn't been addressed at the ROM level? from my brief searching it seems like it occurs on most devices.

I think including the apk in future ROMs seems a definite possibility as this fix released very recently.
Hi all, new iconia owner. Root experience with phones but not much with tablets...yet. I had done some research for awhile and tried a few tablets. Decide I liked the Acer the best. Only thing was the 3.01 was draining battery with the searching for cell service issue. It seems the 3.1 update fixes this battery drainer? Yes/no?
Stock 3.1 update, yes. Custom 3.1 updates? No (conditionally! See RichardTrip's post below!).

With latest 1.7 kernel for stock/Taboonay or honeyvillain no problem disabling it
just add ro.carrier=wifi-only to your /system/build.prop
thank you!
thanks! great info, helpful as usual from here! enjoying the acer.

Thanks for the tip, works well.
Could you add that to the first post in your kernel thread, please? Very useful information that a lot of people will want to know!
Similarly if you for some unfathomable reason wish to stay on stock 3.0.1 the Acer Iconia Battery Saver ( https://market.android.com/details?id=com.interphaze.AcerIconiaPhoneDisabler&feature=search_result ) on Market will help you disable the cell search.
modify the ro.carrier thing before flash or change after the flash..? Thanks
Couldn't you also turn on airplane mode and then turn on wifi? That's what I did and it seems to make sense that it would stop the cell service search.

Well, I personally use airplane mode to turn off wifi when not needed. Then when I want to go back online I just tap on the clock and turn airplane mode back off.

Why do you have to turn back on to go online...?
I searched and found nothing like this.
When I boot my Nook Color, running Cyanogenmod 7, any recent nightly, wireless is off, even though it was on before booting.
I open Notifications, tap the wireless, it turns on and works fine. I've checked, airplane mode is not on.
Updating to newer nightlies doesn't work. I'm pretty sure this used to work. My glacier doesn't have this behavior.
Any thoughts on how to fix this so the wireless state is retained over boots?
I have the same thing but I actually prefer it this way since I use it so much for reading.
I think those lately night builds have screwed up a few things such wireless OFF on boot. Another itchy part (for me) is the Terminal Emulator somehow got blue background and when "exit" command, it doesn't exit but I must force it off under Managing Applications.

Ah, thanks. I suppose I can't file a bug since it is a nightly, I'll mention it on the appropriate thread and hope.

Press the menu key, then "Reset term".
Yeap, that's another less painful way to close T.E.
Try downloading android assistant from the market and checking to see if you have airplane mode on through the app.

I had it, and got rid of it because it wasn't doing anything for me. I'm pretty sure I had checked this before *and* I have flashed several times, but I just got it and...the airplane is blue. I've got a thread on a dev thread, I'll ask about it getting fixed, clearly shouldn't be happening.

It should not be blue. Tap on it and it should turn gray. Problem solved.

It's an Android problem. Something to do with missing radios. Happens on the touchpad too.

Definitely not a nightly problem, it's that way in the official release too.

Some smart CyanogenMod users fixed this problem. Perhaps their methods would work for you as well as they worked for me.
I guess we just have to avoid accidentally enabling airplane mode.
I actually prefer wifi off on boot as I don't need it most of the time and it just drains the battery.
Hello ,
I am on DeoXPer Pure MM 3.0 (Touchwiz) Rom what is an really great one.
But now after some weeks (installing this and that) I noticed whenever i disable wifi the wifi-icon starts to blink. It is alternating within ca. 1.5 seconds. Its not only a visual effect - in the wifi section the slidebutton ist alternating too. When I touch the button i can reactivate wifi and the near wlan is connected. The problem is that i would like to deaktivate wifi sometimes to safe battery. This strange behavior is very batterydraining. I wiped memory reinstalled apps (with data via titanium) but at some point the missbehavior reoccours. Do you have any hints for me to identify the misbehaving app or config?
Thanks in advance

Google is up to something me thinks as when I turned the gps on today the wirless scanning re activated.
I have used alot of roms but I always go back to stock as I have had less bugs that way. If I was to flash another rom I would choose Omega rom or just stick with stock and a custom kernel. Cheers.
