I know Im not the first person with this problem, but wondering if there is any known solution short of a return for a different one. Got an 8gb a couple days ago. Hadnt used it that much until today, because I also have a 4gb that Ive been using. The battery on the 4gb seemed pretty good to me. Would typically be over 20% by the time I went to bed. But today the 8gb, with the same average usage I was giving the 4gb, gave me the "low battery, 20%" warning at like 3pm!! So I come home and charge it. After about 6hrs on the charger, the plug icon is showing (has been showing since about hour 3) but you can tell there is still a percentage of the battery that is not filled. Compare to the 4gb, it has the plug, full battery, and the glow. Also, I noticed today the usage stats on the 8gb dont work, I assume because it wont take a full charge. Anyone found a fix, ie restoring or something? First pic is the 8gb that wont fully charge, 2nd the 4gb.
