Restrict Motorola Droid to 1x (3G disabled)

I get great reception on my Motorola Droid, but if I am running low on battery or am in an area with spotty 3G coverage, it is nice to be able to restrict the phone to using 1x data. With 1x all regular data services work, it is just a much slower connection and also happens to use a lot less battery (so I hear, I haven't actually been able to test the battery usage personally). The technique I use works on the Motorola Droid at least, I haven't tested it on any other phones and does not require any special ROM or ROOT powers.

Start by opening the "Phone" app. Dial this number:
*#*#4636#*#*
To make it easier to remember, 4636 is "info" on a dial pad. Anyway, as soon as you press the final * you are taken to a special menu that lists four options:
Phone information
Battery information
Battery usage
Usage statistics
Touch "Phone information". Scroll down until you see a a drop-down menu labeled "Set preferred network type". The default selection should be "CDMA auto (PRL)". Touch the drop-down and select "CDMA only". As soon as you do so the 3G indicator on the bar at the top of the screen should be replaced with a 1x icon. Touch the "home" button to leave the menu. When you are ready to go back to using 3G just follow the same instructions and switch the drop-down menu to its original value.

[I know that screenshots would be really helpful here, but I really didn't feel like installing the SDK just to be able to take some.]

  1. Thanks, this was very useful for me, albeit for a slightly different reason, but I also needed to restrict my phone to 1x and this worked like a charm.
