That's when you have to be more careful with what you mean by "signal strength."

If by "signal strength" you mean the signal-to-noise ratio of your carrier band in a certain area, then greater signal strength actually means less battery consumption. The phone will not have to spend as much power amplifying the signal and separating it from the noise; also, because the signal is clearer, the phone can turn down its output pwoer for the signal it sends back to the tower (the strength of which is regulated by the tower, BTW).

When most people say signal strength, however, they are referring to that below-zero RX value that represents the absolute magnitude of "signal" (be it real signal or just noise within the carrier band) your phone is paying attention to. In this case, greater "signal strength" generally requires more battery power, as your phone is grabbing more signal from the airwaves and will require more power to filter and sort through it to find the actual tower signal.

So basically, it can go both ways: a radio may have algorithms that enable it to zero in on the tower signal more efficiently, essentially giving you better "signal strength" (actually signal-to-noise ratio) and saving battery power. At the same time, one radio may be more "agressive" than another, running more filtering and amplification to locate a tower signal in more difficult situations; in this case, greater "signal strength" requires more battery power.

The bars you see on your phone are inversely proportional to the amount of amplification the phone is using to locate the tower signal; greater amplification = less bars and less amplification = more bars. Therefore, if you see more bars with a particular radio, that radio is saving you battery power. It may not be as effective as another radio, however, at keeping your calls connected when you drive through tough no-bar or one-bar spots.

At least I think that's how it works.

These are the readings I am getting and I never, ever have full bars. I don't know if it is the rom I am using or what but I would like some input.

Cell: HTC Touch Pro
Carrier: Aliant/Bell Mobility (located in Atlantic Canada)
Rom: MightRom 6
Radio Rom: Telus 1.04.05
Field Test Results:
Rx Power -81 dbm (This goes as high as -92 dbm)
Rx Ec/Io 14 dbm
Rx FER 0.00

Thanks!

I went through and tried various roms for WM 6.5 and they all did the same thing with regards to the signal bars.

I ended up putting MightyMike 4 rom on my phone and it works great. I don't know what it is with the WM 6.5 but WM 6.1 works fine.

i just loaded the newest VZW radio, thanks for the upload
..lets see how it does for my batt signal and so on.

First post should probably be edited to add the debug code fix cab, I had to search the thread to find it to make it work on my VZW TP with mightyrom 6.

I will say it seems the shipped VZW radio works best from my house in austin, tx. I will experiment with signal strength at different places around town.

thanks for this thread!

however, i don't think that the release date really matters because the software you flash changes how the hardware radio in your phone acts. it doesn't fix or add anything that a previous radio didn't have... (someone could get better results in their area with the oldest radio than with the newest)

I completely agree. The names and versions of these radios are not region or carrier specific. In my instance, I use Telus 1.04.05V in the bay area (Northern California) on the Sprint carrier. There's a post somewhere in PPCGEEKS that poeple have listed the radios they've used in the their areas but I can't seem to find it in the threads anymore.

I think i went through 7 radios in 7 weeks before sticking to the TELUS ( I was getting tired of tracking results ) You just have to be patient...

I'm looking for 1.14.25.05 that NRG recommends to use for his latest rom. Anyone know where I can get it or am just being stupid and it comes with his rom?

that's a gsm radio. not for your phone. the only ones available for your phone are in the first post of this thread

[jacker]

Yeah , scrolling further down it redirects me to here for cdma. Anyways , the last on for sprint , is the latest I take it , right?

Yes, but you can use any of the radios in the first post. they are not carrier specific. there's also good info in the faq's below the radio download links, if you haven't already read it.
