    Ever since changing my preferred network to CDMA auto my phone's battery life shot up to an up time of about 16hrs and awake time of about 4hrs at 50% on a single charge. :D

    This doesn't mean a thing. Take a video of you showing that, then clicking Usage and showing us the "Time unplugged" too. Otherwise this is meaningless since you can have it plugged in during this time / part of this time.

    Not to mention it's already on CDMA auto by default.

    That's not true. #*#*4636*#*# and check it for yourself. Mine was set to GSM (prl). After changing it, my battery time improved as well. Not conjecture, fact.

    Does this have to be called?
    Does this hurt/help reception?
    Are there any negative side effects to this?

    1. No it goes to it at the last hash symbol
    2. No it doesnt do either
    3. Not that I know of but the preferred network type is the only thing I changed

    Go to your dialer and dial *#*#4636#*#*

    click Phone Information

    Menu>Select Radio> Force Close

    Scroll down you will see that your Default Radio is GSM (prl)

    Hit the drop down menu and select CDMA auto (prl) then hit the back button, after it finishes you can hit the home button and you are finished.

    It is changed.

    No the ONLY effect that I've had is LONGER battery life. To help reception go into your dialer and dial ##778 and hit Call.

    Click Edit Mode the Pass Word is 000000 then hit OK.

    Click CDMA Settings

    Scroll Down to Home Page and click it.

    Change from EVRC to EVRC-B and click ok.

    Press back and back. You are finished. Better signal strength and better call quality. (For me at least).

    Phone starts out as CDMA, when you cause the force close it causes it to go to GSM, then you have to change it back to CDMA. People have over-ripe imaginations. ...and yes I've done this. It did nothing for my battery life whatever.

    I noticed this as well. Ah first I thought I thought "hey, mine's set the wrong way!" but that was only after the force close, which had reset it. No battery gains, sadly.

    It is true. Neither conjecture nor fact, just misunderstanding.

    It is set to CDMA by default. When you go into the radio menu and it force closes, it just happens to start on the GSM option. Mine, yours, and everybody else's started by default on CDMA.

    So there is no battery improvements, signal strength improvements, or any other effect because literally nothing is being changed.

    Now what you mentioned about dialing 778, THAT can indeed improve call quality. In some locations. For other locations, it can cause entire loss of signal. Just have to try that one for yourself. YMMV.

    Thanks. There really should be a field called "Time Until Battery Discharge" or something like that. Something that shows how much time (hr/min/sec) of how much battery life is left.

    Completely agree!!

    Be careful people, you need to be in an area that supports whatever change you make otherwise you will hose your reception completely.

    If you change to evrc-b, be sure you test it out. My area did not fully support it.
