Before the last ota I was connected all the time, using CDMA only, and easily flipped phone into 4g when I needed it. Battery life was fine, lasted thru the day. After ota I find I often have no 3G data connection, but can switch to 4g and the data flows fine, but doesn't stay connected. Called Verizon this am and the tech did a reset, and had me pull and reinsert the sim card. She said that I am in a heavily saturated 4g area and I should use it, that my battery life will be fine on it...phone is staying connected to 4g, but battery is dropping fast....could be because I am checking all the time. She also said when i travel to rural areas i might want to lip it to cdma only to conserve battery, so it wont search for 4g. Does this sound right, or do I have a problem? I've had the the phone since the release date, and this is first issue I've had. Another problem cropped up since the reset/pulled sim: the battery use won't reset, it's still showing time/use since prior charge. I used to (yesterday) refresh it and see what current usage is...now it shows 24 hours and running totals. Any help there? Thanks for your help!
