Yea, its true. Thats why your battery dies quickly in low signal areas.

Re: Force Roam - Found!
 

I just thought that was from it searching for the signal all the time.

Re: Force Roam - Found!
 

Take a look at ##DEBUG#. For newbs, go to the dial pad and enter the string.

The "receive" portion of the radio is passive in that, it cannot "boost power" to "grab" better signal. The "transmit" portion of the radio has the ability to transmit up to 600mW (per FCC requirements).

When signal quality is good, the phone does not need to TRASMIT at higher power levels and therefore does not drain battery as quickly. When signal quality is poor, the phone may need to poll the cell site more often in order to establish connection and/or switch between 1xRTT and EVDO. When EVDO signal is not good (DO is serviced by a seperate cellular element within the cell site), the phone switches to 1x. The act of repeated connection and switching between DO and 1x will consume battery.

When the Rx s/n is low, it causes the phone to transmit (Tx) at higher power in order to reliably reach the cell site. Again, the phone cannot simply "boost power" to go out a get better signal.

On the subject of roaming--since Sprint can only roam at 1x on Verizon, having the phone on forced roam will cause the phone to be locked at 1x. If your phone is constantly switching betwen 1x and DO while on Sprint (therefore causing the phone to turn on all the time), having it locked on Verizon 1x WILL save battery.

On the other hand, if you have good DO coverage and the phone does not switch betwen the 1x and DO, then the point is moot.

Thanks to the OP for the registry change to add the option of roaming! Works like a charm on my Sprint Diamond. I have a weak Sprint signal at home.

I assume that pointy triangle icon in the taskbar means I'm roaming?

Any way to find out what network I'm roaming on?

Cheers,

Jeff

Re: Force Roam - Found!
 

well I have tried this before and sometimes it works. in roaming, his *2 and occasionally you will be connected to customer service of the company you are roaming with. I was connected once with Cricket and Verizon but most of the time it doesnt work.

Re: Force Roam - Found!
 

Same problem here. I did a hard reset and have been changing the options very carefully, but it keeps searching for service when put in roaming mode...

Re: Force Roam - Found!
 

well let me know what you find out becouse i still havent been able to fix it.

Re: Force Roam - Found!
 

Could it have something to do with the latest PRL update that Sprint pushed?

Re: Force Roam - Found!
 

I have had the same issue when you can't get a good sprint signal, that the battery drains really fast. Though this is past experience with other phones and I think this applies to the diamond as well.

The two options you have are:
1. implement the reg edit for roaming, knowing what that will do to your contract
2.Turn off the phone

Re: Force Roam - Found!
 

I also want to add I renamed the settings under 'network service' to (using juicy 4.4):

home=Sprint
*=Automatic
automatic b=Roaming Only

It works just fine with no errors nor problems. Regedit works as advertised.
