No way to do it if you are outside the 15 day return window. Filing an Insurance claim that is bogus is just asinine...as well as illegal and immoral...this is why insurance premiums will continue to rise as well.
How limited is your Razr vs battery life? What kind of battery life are you expecting? Are you in a full time 4G coverage area? Do you have wifi availability...do you take advantage of it? Have you utilized the Smart Actions to negate poor battery performance or extend battery performance?
I only have 4G at work, therefore I have a Smart Action that triggers when I get home that switches me to my home wifi, turns off my GPS and dims the screen. On average, between phone calls, texts, YouTube and Winamp use, and Droid Forums surfing, I get 14-17 hours @ 30% battery left.....
