I HATE when the phone give me edge connection with 4 bars, when i have 3g connection available with 3 bars, and i must wait the phone to chose 3g again or i must go upstairs.
How i can fix this? How i can set that ONLY when i'm browsing or using app that need connection the phone go to 3g?
Shouldn't Tasker or Juice Defender be able to make such definitons? I'm wondering, too, which app to use to tell my phone e.g. "only use 2G when screen off" which would save me a lot of battery during the day working in a low reception area.

3G has become the clearest battery drain outside of screen usage, so I'm desperately looking for an app to shut it off when I travel for my Droid. I know that for some reason this could not be developed for Verizon like other networks because of the CDMA network, but I would imagine that a solution could be developed for rooted users since getting a Wifi signal essentially turns off 3G while still allowing for texts and calls? Could the phone be tricked into thinking it has connected to a Wifi signal? I'd pay for an app like this and I think others would too....
Go to the dialer and enter: *#*#INFO#*#*
Then go to Phone Information. Then scroll down to where it says "Set preferred network type:" and change it from CDMA auto (PRL) to CDMA only.
try juice defender in the market. it basically turnes off 3G while the phone is locked saving a ton of battery life! when you unlock the phone it turnes 3G back on! only problem is it takes a little while sometime for 3G to kick back on... but you could enable the juice defender when you want and disable it when you dont need the extra batttery life! give it a try! its free so if ya dont like it you can just get rid of it!
You can also use Quick Settings which among the other settings you can quickly change allows you to disable the use of 3G. It works great on my Milestone.
Or you could use APNDroid (on the market too). It has a widget to manually switch on/off the 3G net, but still allowing to use the phone/text.

Your milestone is GSM. Quick settings does not work for CDMA phones.
To the OP, use the widget called Easy Switch. It does 3G and GPS (among other things) with the click of the button. It doesn't take you to an options menu, it just works.
+1 on APNDroid. Simple and just works.
Another option for droid is cyanogen6. I know rc2 has 3g on/off built into droids power control widget.

use cynaogen...u can turn off 3g in there
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.

Well after many searches and a lot of trial and error, I think ive finally solved my problem of dropped/no phone signal for NAND builds, which in turn has also made my battery life way better since the phone is no longer constantly searching for signal Basically its 4 steps, ive tried each individually with no changes but for some reason when applied all together it works wonders. They are as follows:
1: dial *#*#4636#*#* and go to phone information and choose 'gsm auto PRL'
2: go to settings>mobile networks and check 'use only 2g networks'
3: go to settings>wireless networks>wifi>advanced and change wifi sleep policy to 'never'
4: go to app store and download "wifi keep alive" (free). choose wifi behavior 'always on' and advanced options 'enable workaround 2'
using these 4 steps i reduced my time without signal from 74% to 12% in 16 hours, and im getting 4-5 green bars all the time, at home and work hope this helps
I'm not an expert, but doesn't that mean you are stuck in 2G-Mode for Data Transfer? I believe 3G if available would be faster..... or am i wrong?

yeah, it stays in 2g for data but for me its an acceptable trade off to actually be able to recieve calls. plus you can always switch 3g back on if you plan on doing something that uses a lot of data and switch it back off when youre done
damm i was excited until i saw that you have to disable 3G
Is this a common problem?
or... you could just go to settings/wireless&networks/mobile networks and change the network mode to gsm only (which is 2g) so, same thing.. and you know what? i still have signal issues, just not as bad..

yea i think that option is only on Desire or froyo builds, on all of the GB's ive used it says 2G. i suppose its not gonna work for everyone, it probably still depends on your coverage area, but it definately helped me A LOT. ive been using these settings for the past 3 days and my time without signal has dropped down to 0-5% from the 55-75% it was before, and im no longer missing calls
very useful tips
I ticked the "Use 2G only" checkbox in my wireless settings and all connection problems seem to be gone! (for now)... My data connection used to be terrible... voice connection shaky.
Thanks a lot!
I know this is one app we can try: http://forum.xda-developers.com/showthread.php?t=739530#
But it can't disable switching while do tethering. Can we have this flexible function that we can customize from Settings menu?
I noticed our SGSIII can switch off and on WIFI when the screen on and off. It's good if our SGSIII already have the function what I want and it good enough to now what we do when the screen off, it will not switch to 2G when we do tethering and downloading.

If network idle, it 's will auto down to 3G umts or HPDPA to keep the battery life.
1 hour with auto sync-> 1-1.5%
2g can save battery ?i think not so much with network online.

As I remember correctly AOKP has this feature under their powersaving settings. From what I can tell from my I9000 I always lost mobile data connection entirely when turning screen back on... took 10-60 seconds to get an active 3G data connection again. That kinda really pissed me off cuz it is very likely you need your internet connection when pulling the phone out and turning the screen on ... and in that case having no connection really sucks.
So I never used that option (besides using manual 2G limitation if wanted).

Thanks for the info. My home town just have 2G connection. I think it's better if it directly connected via 2G, rather than the phone continuously searching 3G line.
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.
