I have a Motorola V3x on the 3 network and am 4 months into the contract. I didn't take out the insurance. The phone is no longer retaining it's battery charge with a full charge on standby giving about 18 hours. How do I go about getting the phone repaired or replaced? Should I contact Motorola, 3 or my retailer? Will there be a charge? I have 2 batteries for the phone and both do the same.
