Tell me if this saves you battery -

[leyvatron]

It's been good to me but does it work for you?

I remember doing this for a few other phones with good results.

Now I'm doing it with my Sensation and it looks like its working... but I want more people to test it. Test battery drain and data speeds.

Anyways,
Type *#*#4636#*#* in dialer > Phone info > Change WCDMA to GSM auto (PRL) and that is it. You should see the battery drain less on stand by.


post results here... and a thanks would also be good.

Yes, it does save battery. Same as going into Mobile Network settings.

GSM Auto (PRL): gives me 4G speeds
GSM only:gives me edge speeds


GSM Auto (PRL) isn't in the mobile network settings.

gsm auto prl will save the user a bit more power because it wont force the phone to continuasly hunt for a stronger signal

And just in case you guys want to play with some settings:

WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

So what's the downside? Edge speed more often? If there was no downside why wouldn't it be the default?

I find gsm auto gives slightly slower speeds in a speedtest than wcdma only... (only two settings I use) and that's it.
