Thank you thank you thank you for this suggestion. That 50% without a signal was driving me crazy! After using the airplane mode while I charged last night, my phone has had 0% without a signal all day so far. I still have less bars since I updated to 2.1, however, but as long as I have a signal that's doesn't bother me so much. Strange how doing something so seemingly unrelated can turn out to be the fix.
Great! I'm glad it worked for you.
I'm just glad it is working for people. Only time will tell as to how often it needs to be done. I have had my Eris since the beginning of December and I have restarted it no more than 10 times. That includes the restarts from the 2.1 install.
