Hello!
Many users have reported excessive battery drain and/or/due to intermittent loss of signal using the latest basebands.
I have been trying different basebands myself and found that baseband -36 gives the best combination in battery life and signal reception.
However, there are libraries in /system/lib that are related to baseband and, in my trials,
it seems that they made a difference in how the baseband was functioning in a different firmware than .368 (in which it initially shipped).
In other words, I've simply come to the conclusion that each baseband needs its appropriate libraries.
UPDATE for people asking which is the "best" baseband:
And now, here are the patches flashable in CMW recovery:
DOWNLOAD THE PATCH for -36
(It will NOT change your baseband!!!
It will only flash baseband's -36 libraries in your system.)
DOWNLOAD THE PATCH for -64
(It will NOT change your baseband!!!
It will only flash baseband's -64 libraries in your system.)
INSTRUCTIONS: Of course you need to be on STOCK SE ROM, on baseband -36 or -64* and on any other firmware other than .368 and .062.
Place the patch zip in your sdcard, boot into CMW, flash it, reboot and enjoy!
Works for Arc and Arc S. Tried it on .042 and .058 ROMs.
Even better instructions, by DooMLoRD:
* Here is baseband -36, flashable ftf for FlashTool.
DOWNLOAD baseband -36 (thanks to erwin929)
If this file doesn't work for you, kindly find baseband -36 elsewhere.
* Here is baseband -64, flashable ftf for FlashTool.
DOWNLOAD baseband -64
If this file doesn't work for you, kindly find baseband -64 elsewhere.
NOTE: Test the new libraries for at least 1 day before reporting,
in order to have more thorough proof of the improvement or the lack of it for that matter.
Simply booting after flashing the patch and seeing less signal bars doesn't mean anything by itself.
After running your phone for several hours on battery you can see the battery graph,
in the About Phone section, and check for signal strength, signal loss, etc.

@All asking for which baseband fits best:
Please please DON'T start flashing basebands without thinking about now.
Normally ALWAYS use the baseband which comes with the ROM! For example SE always has the corresponding baseband included. This baseband fits the android libs it comes with.
On custom Roms please read what the developer of the customRom telly you. If he/she has developed the Rom for specific baseband libs.
All other things like baseband patches are tested and developed by other developers which know what they are doing. So if you use such a patch ALWAYS read the manual and the requirements. Because it CAN happen that it is NOT possible to use a GB baseband on a ICS rom and vice versa. The is a little more than "just" libs and firmware. Also the java part framework/base/com/java/internal/telephony....
has to fit the baseband (SE is very special here).
So i hope now you all understand. Please please please leave the decision which baseband is best and which is working to the devs who know what they are doing!!!!!! Don't come here and tell "i tried baeband xxxxx now my phone randomly disconnects data/voice/..."
Thanks

Even better instructions, by DooMLoRD:
step 1:
flash baseband FTF via flashtool
step 2:
boot device and go into recovery
step 3:
while in recovery mount USB storage and connect device to PC
step 4:
copy the patch flashable (update.zip) to sdcard
step 5:
unmount sdcard via PC & also via recovery menu
step 6:
flash this patch (update.zip) via recovery
step 7:
reboot and enjoy!!
u can skip step 3 to 5 if u already have the patch update.zip on sdcard
