Hi, husband and I got new phones Friday. Our poor old Droid 1 units were getting a bit creaky. We really coveted the Galaxy S III, but didn't have the $$ for them. Got Galaxy Nexus units instead. I really like it, but boy, is it a power hog! Looks like the screen is the chief offender. I keep my brightness turned way down unless I am in full sun. Any other tips? I put Juice Defender on it since it was recommended by at least two people in another forum. Just started that today. Also, I was astonished to discover that this spanking new unit doesn't do Car Home! I like to keep the map open with the traffic overlay during my long commute and this morning the phone went dark four times! Is there any way to keep the maps on? (I hope Navigation doesn't do this!!!!) Thanks "Apple can...Droid DOES."
