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.

Is there a way I can toggle between Edge and 3g on the g2 without going into settings? I cant figure it out using tasker and i'm not sure how to use APN droid to do it.
Basically, I want to switch to 2g when I'm at work just to save battery - i dont want mobile data off, i just want it to use the 2g radio instead of 3g.
Ideas? Is this even possible on stock froyo? I know CM can do it.
SwitchPro has a 3G/2G toggle. Available on the Market.
This is in the wrong section.

I used better cut to create a shortcut on the desktop. It works for now, like you I'm waiting for CM to fix most of the stuff that bugs me...
I've been using the "Data On Demand" application on my g2 which turns off your data when your screen is sleeping and then back on when you turn on your screen. It's saved me a lot of battery so far, but as you said you want data to remain on, there should be other applications out there but this is an option.
i wonder since they can turn off data when the screen is off and on when the screen is on if they can do 3g when the screen is on and edge when the screen is off.

Go to the market and install extended controls. Make a widget on the home screen and add the 3g/edge toggle button.

Yea extended controls is the best one. Had switch pro, isn't a great as extended control

Quick, tip, toggling from 3g/edge could burn out the sim card and cause connection problems to the network, or at least that's what the tmob tech said to me. I had trouble with my g2 switch from hspa to edge to cutting off completly, so I called the tmob tech. It turned out I had an older sim card (from the g1, had 3g/2g toggle) and said that that was causing the problem and that eventually it would burn out from switching networks so many times. Don't know if this is true or not but just giving yall a piece of warning. Anyways, I registered a new sim card that came with my g2 and now i get constant hspa and everything is hunky dory
Burning out the sim from switching between 3g and edge makes absolutely no sense to me. At worst, switching from between 3g and edge should be no worse than going in and out of service which, as T-Mobile a customer, happens all the time if you ever go inside. It also seems odd that a supported and encouraged battery saving feature could reduce the practical lifespan of the product. I say chalk this one up to the usual T-Mobile tech BS.
Hi,
I've an un-branded and not rooted Desire (Froyo) and I would like to know if there's an app that would allow me to turn the 3G "on" when I turn de the data connexion "on".
When the data connexion is "off", I would like to stay in 2G.
I hope I'm clear enough, thank you!
Ok this should happen anyway unless your phone is set to WCDMA only in which case it's set to 3g all the timeif it's set to GSM & WCDMA it will switch between 2 and 3g as you wish.
Yes but what if I want it to be connected to 2G all time (when phoning or stand by for example) and connected to 3G when using data (without having to do it manually)?
CM7 allows that through "its" power management widget but is there a possibility to use such an app on Froyo?
Well...no.
Tasker maybe, There is an option for 2g/3g switching, I haven't tested it myself though just a suggestion!

This option is unavailable on some phones (like my DHD )
This one here works fine. Although with cyangogen mod. You might just get lucky if it works for you

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.

I noticed that by default this phone is setup to use "Global" as the preferred network mode. I'm thinking that means it'll try to use CDMA, LTE, and GSM networks. I noticed there's a setting for "LTE / CDMA" and I'm thinking this setting may save some battery because the radio software wont try to use the non-existent GSM for Verizon.
Anyone play around with this setting and notice a difference? I just switched to LTE / CDMA. I lost data until I rebooted and now everything is working fine. It's odd that it was set as Global to begin with.
I did the same thing you did. I notice no difference but it does work fine. I also tried fooling around with lte on/off app. Is there a simple widget that can be used to toggle between 4g and 3g? If I know i won't be using the phone for a while i would like to switch to 3g to save battery.

You can download an app called Phone Info -- open it up and go down to Network mode, select CDMA (Auto) that will force 3G only.
It will remain until you reboot.
I used to do this with my OG HD and it did save quite a bit of battery but in my semi-scientific tests the difference on the Maxx HD is almost nonexistent, certainly not worth the reduction in speed or the inability to use data and voice simultaneously.
I don't know if you noticed but, data and voice simultaneously is possible even in 3g mode with the razrHD Max. The greatest android phone verizon has ever offered.

I've seen a lot of people have issues with GPE getting 3g signals, myself included.
This boils down to the lack of network settings options available. 2g checked or unchecked. I use 2g mostly as I use WiFi for the most part. When off WiFi though 3g was terrible. Would often end up with 2g even though unchecked.
I've found a solution in another thread to access the Testing app and set network to 3g only from there.
Enter *#*#4636#*#* into the phone dialler to enter the testing app. Select phone information and change network mode from there.
Works a treat for me in the UK.
I've set up a Tasker task to launch the Testing app. This can then be tied to a homescreen shortcut or gesture. Much easier than using dialler.
