Hi Recently I have purchased a DMC 320+ and I think this presents a problem. In save mode battery range is about 48h or so and the battery indicator is always indicating full charge till the last half an our. After this time battery indicator decrease directly to zero and is marking empty, a message battery low appears and device switch off automatically. After few cycles (3) of charge, my 320+ don't work more neither connected with usb cable. ??? any suggestion? Can someone tell me about battery range in save mode?
A li-ion battery also has decreasing voltage like any other battery type. It just means the device utilizes only a smaller percentage of the fully charged battery than possible. That could still be more than 60% of entire charge though. That's probably done to enhance battery life. A li-ion batterys life is longer when charged while still pretty much full. Same as li-poly in your smartphone. (protip)
