turning off 4G

[ctjoe]

I know that using 4g will eat up power. I hear people talking about turning off 4G. Is it possible to do that and just use 3G ? I am looking at this phone as its one of the 3 choices replacing the Fascinate and not looking to use 4G. Thanks

Yup, you sure can. Menu > settings > wireless & networks > mobile networks > system selection > CDMA mode

this will shut off 4G

I switch from 4g and 3g everyday to save battery. Does anyone else have problems reconnecting to data network after switching off airplane mode?

i sometimes have problems with reconnecting after plane mode but it hasn't acted up in a while.
I personally havent seen a difference between 3G and 4G battery life when my phone isn't in use. I guess it depends on how strong the 4G signal is in your area and how often your phone switches between 3G and 4G

I totally agree here. I live in a 3G area and was recently on vacation in a 4G area. I used my phone a lot more than normal while on vacation b/c we got rained out while out the beach. The 4G signal absolutely had NO affect on my battery life, honestly it lasted longer w/ the 4G signal. Experience it for yourself before shutting off the 4G.

It's not my experience that shutting off 4G has any impact on battery life, so long as I'm in a strong 4G signal area.

Hi --

Just thought that I'd pipe in here about this, since I switch between 3G and 4G daily based on my phone usage.

I'm in Manhattan, and according to my phone, I have 4 bars of both 3G and 4G.

With 3G on, I get around 30 hours battery life from the phone (that's mostly on standby; solid 10-12 hours use). Typical usage: Bluetooth on, music playing over BT, light web browsing, email checks every hour.

With 4G on, I get around 20 hours battery life from the phone (again, that's mostly on standby; solid 6-8 hours use). Typical usage: Bluetooth on, music playing over BT, light web browsing, email checks every hour; downloading app updates, maybe some video streaming.

I tried for a day keeping my phone on 3G to see how it affected battery life, and saw no difference at all. Guess it really depends on your service area more than anything else... because I was hoping for serious savings.
