So far i only had this throughout the night, so i cant comment on it too much, but so far seems normal. Even if the battery does get consumed at a faster rate, thats a small price to pay instead of missing an important phone call

I'm guessing there's no way to factory reset these values. Can someone with Sprint please post their default values for the C0_BC1 and C1_BC1 keys? I know they vary by phone, but at least then I can get a ballpark. Right now I think I remember C0_BC1 was 1746, but I have abo****ely no clue what C1_BC1 was.

These are my default values:
File # 1670: NV_C0_BC1_VGA_GAIN_OFFSET_1 (default 1772)
File # 1698: NV_C1_BC1_VGA_GAIN_OFFSET_1 (default 2550)
File # 1749: NV_C0_BC0_VGA_GAIN_OFFSET_1 (default 2271)
File # 1776: NV_C1_BC0_VGA_GAIN_OFFSET_1 (default 2989)

Defaults: 1746 / 2285 / 3044
1X: -92
HDR: -81
Battery: 440mA, 11mAh
Tweaked: 1 / 1 / 1
1X: -73
HDR: -69
Battery: 394mA, 10mAh
Conclusion: Holy crap! An increase of 20dBm for 1X and 10dBm for HDR with no apparent impact on battery life!
Now, before everyone gets all excited, realize that this is almost certainly empty amplification, meaning the noise is being amplified as much as the signal, resulting in pretty much unchanged call quality. In fact, while testing I noticed that while the signal strength changed significantly, Ec/Io (I believe this is signal-to-noise ratio?) did not. Still, this has the potential to work wonders in low-signal areas, where the SNR is good but the signal is too low for the phone to detect. I cannot wait to test this on the road.
At lunch time I'll try setting C1_BC1 to 1 as well; I see no reason why we should leave that one out. |
Hey, thanks for pointing out C1_BC1, i guess i missed it.. i just changed that to 1 now. Thanks!
