I don't have a data plan so I have data turned off always(I use WiFi only). My question is since data is off anyway, will setting the option for 2G only in Mobile Networks make a difference on battery life?

If you disable mobile data, there is no mobile data. 2g is mobile data. To answer your question, no.

I dunno, but sometimes in different areas when i get a bad signal, setting to 2g only helps even if i have data off.. shrugs.

Umm no that's not the case. "2G" is GSM and Edge is data (of the 2G kind, there's also 1G which uses GSM but uses GPRS for data). This is why i freaking hate "G"s!!!!!!!
Using 2G only networks will force the phone to use GSM for voice rather tham UMTS/WCDMA (3G).
There used to be the case where using GSM would save power because 3G radios were power hungry (similarly to LTE radios now) but they've long been integrated into 1 chip now so power savings would be nill or very small.

Evening all,
Would anyone be able to enlighten me about how Android selects between wifi and 3g?
i.e. If I have a wifi connection established what governs that traffic is routed via the wireless connection?
Thanks!!
I have a data counter app (3g watchdog) and looks like when WiFi is in range android use it for data than 3G.

That what I expected. REason I wanted to make sure it defaults automatically is I'm going to France (live in UK) and want to use the phone for data without incurring stupid data charges for roaming
There is an option to turn on/off data roaming so when you go abroad you don't have to worry.

If I enable 3g, my battery only can stay around half day. But when I only enable wifi, it was almost double the time.
Anybody know why?
Sent from my GT-I9000M using XDA App
yes... same here 3g uses more data.. i find if i turn on wifi at night battery lasts longer.. and if you disable data totally it lasts even longer.
Yes, if disable all the internet connection. It can last 3 days for me.

That's normal and quite reasonable.
With 3g your phone has to transmit with much higher energy (since the antenae are potentially thousands of meters away). With WIFI it only has to transmit to 100-200 meters max.
Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

Is it possible to set to '2g only' in froyo?
So far I can only find the option to completely switch off data, but not choose the type of mobile data connection.
Sent from my GT-I9000 using XDA App
Yes switching to '2g' only is easy, you can find it in wireless settings under mobile networks. It's the 'network mode' on there.
Myself I use 3G only because I listen Internet radio a lot in my car and of course 2G is not enough and if it's set to both 2G and 3G the connection breaks way too often. Of course I couldn't do that if there were areas that would not cover 3G.

Here is the right answer, and the battery consumption can be quit high if you have poor 3g reception or u are just between edge/3g signal the phone consume much more power when it tried to find the best signal

In Network mode, select GSM or WCDMA for 2g?

Is that really true? When Idle, is the phone transmitting? Or only receiving?
Just go and install JuiceDefender, It turns off 3G when screen is off. Simple. To set to 2G only then choose GSM.

I don't call, and when I do, I voip. Is there any way to leave the HSPA/EDGE on while killing the battery consuming radios that take cellular calls? I wondered this while looking at the *#*#4636#*#* menu.

It's the same radio so no you can't save power by disabling it.
I'm not sure how cellular works, but I can imagine that having push call notifications would require my phone to scream to the towers often. I wonder then, could we make a program that enables radio only when programs try to connect, like airplane mode on sleep.
If you need battery life, look for it elsewhere. The solution you are looking for isn't possible

Doesn't the nexus 7 3G already do something nifty to cut the power consumption of data? It has the same battery and it lasts just as long as the WiFi model.

I haven't used it in a while, but I think juice defender ultimate is able to do that. It is a couple dollars from the Play Store for the ultimate version.

Both data and voice use the 2G radio and/or the 3G radio. (LTE is data only.) So, you can't just "shut off" voice and keep data (unless you use LTE).
The N4 essentially has 3 radios: a 2G radio (GSM/GPRS), a 3G radio (WCDMA), and an LTE radio. What you can do, is turn 1 or 2 of them off so that you are using only 2G or only 3G, or only LTE (if you are in an area where your service provider uses LTE on the AWS band). Turning off the LTE radio (off by default) certainly saves battery, but I don't think you will get that much more savings by turning off the 2G radio.
As mentioned before, it's all the same. That's like wanting to save gas by turning off the engine but still get where you are going. There's no seperate radio for data/voice. Basically WIFI is your "turn off voice but still have data" only option.
Dear friends, good afternoon
I hope you are doing well.
Does anybody knows how to manage 2g to 3g automatically?
I mean, is there any way to let 2g working when screen is off or when is in standby (not using an APP) and in the moment that you open an APP, the 3G connections starts automatically?
I had this idea few days ago. Would be AWESOME to save Data Plans and Battery. But I am not sure if it is possible.
I already use Greenify + NFC Task + Juice Defender ultimate (to turn on and off 3g) and my battery is during around 20 hours. However, I want to reach the edge of the device.
All the best for everyone.

If you don't use LTE, then Llama (free app) can automatically switch you from 2g to 3g when your screen turns on and back again when it turns off.
if there is data flowing, 2g will end up using more battery. if the data is flowing, it is slower on 2g, therefore it takes longer to finish. if it takes longer to finish, itll end up using more battery. ive been using lte, and have had better battery life since. i see a minimum of 5 hours screen on time.
got it

I do not use 4g here because Gnexus 4 is not compatible with 4g frequency in Brazil (2600 mhz)
Llama works a bit like smartactions from motorola right? (i will take the weekend to explore it better)
Does Llama work as a NFC tasker as well?

right.
i used to believe, just like you, that 2g saves battery. so id use 2g instead of 3g, and the battery would go down quicker.

I'm using 2g when i'm not surfing or downloading anything(except whatsapp and hangouts), and when i'm going to surfing etc. i'm using 3g so i can save battery. But i have to do it manually, with quick toggles this is not that hard. :good:

2g saves battery when you're connected to Wi-Fi.

I don't know what smartactions is, but you set conditions and actions fire off when the condition is met. NFC would require the secure settings plugin (app from store) and needs root.
As an example, when I connect to Wi-Fi, my phone switches to 2g and my pattern lock is disabled. When I disconnect from Wi-Fi, my pattern lock is re engaged and my network mode switches back to 3g.

its not that it saves battery, its that you are using wifi as a data connection. as soon as data will start flowing through the 2g connection, battery drains faster. its the same principle as using a 3g or lte connection over a 2g connection. heck, you can save the same amount of battery using wifi and shutting off mobile data completely.

In my network, the operator can set the policy to force the user to use 2G or 3G network first.
By default it is 3g h+ when I turn on my data plan. I only see edge after recovering from a signal loss
