    First off, this may apply just to me, and some of you may deem this is an unworthy, useless thread since its something so obvious that one would be just plain dumb to not have realized this to begin with.

    Ever since i bought my Bold 9930 (verizon), the Network Technology setting has been set to Global - by default! And i always thought that if its a default setting then it would be the "ideal" setting predetermined by RIM for users who didn't know any better.

    So i decided to change it 1XEV and BOOM ! my battery life is now DOUBLED.. literally! Its been 24 hrs exactly since i unplugged my phone. Ive had a total of 30 mins of talk time, with 75+ texts, 30 emails, and 10 mins of browsing. And its sitting at 70% and this is 24hrs unplugged!! Everything still works and everything is just as fast. Text are instant, emails are pushed instant, browser and calls works just fine. If my usage dont change, does it mean i will be able to go 3 days ????!!

    I dont know what the settings are for the bold 9900 but im assuming you'll be able to figure it out.. maybe someone else can chime in.

    Now granted i dont use any of that Twitter, Facebook, Wikitude, etc..but i now that if i were to use them i wouldn't have to worry about my battery draining uncontrollably.

    For those who dont know how to get to that setting ---
    Under Options-Network and Connections-Mobile network-Network Technology - 1XEV.

    It may or may not work for you, but it sure as **** worked for me.. I could really go two days with moderate/heavy usage if i needed to.

    Phones come from RIM preset to access the high speed networks to make full use of the new hardware.
    1XEV is slower than 3G/H+. Most of the time you won't notice unless you are streaming video, etc.
    So if it is fast enough for your use, then keep it on 1XEV and enjoy the extended battery life.

    Is this the equivalent on the 9900 to going from 3G to 2G?

    The OP is talking about the 9930 which is the CDMA version of the 9930 and doesn't have the 2G/3G setting.

    The setting he changed turns off the GSM radio on the device. The Blackberry actually asks you the first time you turn it on with a SIM (most come preinstalled with a SIM) if you want to enable "global" mode. If you answer yes to this question then the CDMA and GSM radios will be on at the same time looking for signal. Which could have some impact on battery life.

    This was the first setting I changed when I turned on my 9930 and my 9630 before it

    we are talking about browser speed correct? and it will have no impact on how fast our emails get pushed right?

    That's correct. It doesn't matter what setting or network you are on, you won't notice any difference in time it takes to push email.

    To clarify look at wikipedia for speed and generation diffrences List of device bit rates - Wikipedia, the free encyclopedia
    1xEV is means CDMA for voice + 1xEV for data
    2G means GSM + GPRS + EDGE
    I wonder if there is a setting for something like 1xEV+2G only for the GSM

    Nah, this is old news that has been covered before. It does help battery life but it still sucks on the 9930.

    Useless in that once people do it they won't see any major differences in battery life?

    Thanks to the OP ... I've read many threads about "dumbing down" the device in order to salvage battery life.

    I guess my only real problem is that we shouldn't have to dumb down our devices in order to gain extra battery life. There is simply no excuse on RIM's part for making suck a sleek device, their flagship unit if you will, with such poor battery life.

    Maybe I'm just cranky because I about to go over to my third device now because the microphone on my second one has just been deemed defective.

    Everyone who has a 9900 in this thread:

    THIS IS NOT THE SAME AS TURNING OFF 3G ON YOUR PHONE!!

    THE 9930 IS A CDMA PHONE. 1XEV IS 1X (2G) and EV-DO (3G).

    The 9930 has CDMA and GSM radios. This setting turns off the GSM radio. IT HAS NO EFFECT ON THE SPEED OF THE INTERNET ON THE DEVICE. It just means that if you happen to travel abroad and have an activated SIM in the device it will not automatically switch to the local GSM network.

    This is why this is the default behavior of the phone when a SIM card is installed. RIM assumes that if you have a SIM in the device that you're going to want to use it when you get in range of a GSM tower. Unfortunately the device seems to ship with a SIM on the major networks which defeats RIMs assumption.

    No, this is not correct. 1XEV is 3G. Selecting 1XEV in options only turns off the gsm radio and has zero effect on device speeds if you are using it on the vzw network.

    To be honest with you, i haven't seen any type of slow-downs at all. But then again, i dont do any intensive downloading - its mainly quick look ups on hourly weather, top news of the day or what have you..My browser speed has been the same as before, my texts and emails are instant.

    Thats kinda what i thought.. So if im not travelling abroad, why use the GLOBAL setting.

    I didn't say everyone had saw it. If someone was so inclined they could search for it and instantly have a much larger conversation on the exact topic that already exists.

    Android has similar mobile network settings that can massacre your battery life depending on what you pick and your coverage as well.

    Same goes for the turning your sim card upside down trick... Also discussed in length for the Tour and 9650.

    1xEV is CDMA 3G, while EDGE is a GSM 2G (2 completely different cellular networks).

    Verizon users might find this breakdown of CDMA generations (with theoretical download speeds) interesting: http://www.superbank.ru/images/EVDO%...0evolution.PNG
