Battery life

[Toyland]

I have a Kyocera 2135 that is about 10 months old. The battery seems to need charging much more often during the last two or three months. It used to go two to three days with light to moderate use. Lately I've had the battery run out or come close by the middle of the second day.

Is the battery near the end of its useful life? At a cost of $60 per, I expected it to last much longer. I've heard a lithuim battery will last about 300 charge cycles, but I've probably only put it through about half that. Is mine dying prematurely or is this normal?

Could just be dying prematurely. Any Kyocera phones I've used generally have pretty good life on the battery, even at 10+ months old. Depending on your provider, they may or may not be willing to exchange just the battery.
