Query: Terrible battery life - and terrible support from Panasonic

The phone worked very well . . . for about two months. It was around that time that the battery life virtually disappeared. After a full charge, we couldn't get more than a half an hour before the battery indicator would start blinking. To make matters worse, Panasonic was not in the least bit helpful about diagnosing the problem or attempting to look at the phone. I ended up having to buy a new battery on my own.After installing the new battery, I saw the problem disappear . . . for about two months. It's back to the same problem and I'm not willing to torture myself by going back to Panasonic for Round 2 of fighting this problem.So, I'm going to buy a Motorola instead. Their new MD681 expandable system looks appealing.IN SHORT: Panasonic is not what they used to be and you are buying their products at your own risk. Don't expect any help from them when you run into problems (like the common battery life problems).
