I yanked my sim card out of my phone as well...it was set to CDMA only before but i still saw battery drain from signal searching. Hopefully this fixes that!
So what effect has this had on your battery life? If you pull out your sim card it says no sim card on the lockscreen and it's kind of annoying but i'd be willing to put up with a minor annoyance for improved battery life
Well I've only the SIM card out for one full day, but I saw no impact on battery life. It pretty much stayed the same, I think im just gonna bite the bullet and order an extended battery next paycheck. The battery life is worse than my Original Droid, hopefully with the extended battery i'll be able to make it a full day with moderate/semi heavy use. I love pretty much everything else about the phone, though.
What do you expect me to do in class when fall semester starts, pay attention??
I guess I'll probably do the same thing when i get my next paycheck, this phone is great other than the semi-crappy battery life and bloatware. It is definitely a worthy replacement for my OG Droid
