I own a Cowon iAudio X5 portable music player. I've had it for a little longer than a year. In that year, its battery life has gone from a reasonable 8-10 hours to about 2.5 (if I'm lucky). I've also had some problems with its proprietary "adapter".
Fortunately, I people sell the adapter for a reasonable price online. But I've had a tougher time finding information about a replacement battery or anything I might do to increase the existing battery's running time. The best I've seen is "buy a XXX brand mobile phone battery and a soldering gun."
Would switching to Rockbox make a difference. Any ideas? Thanks in advance.
