Battery problems with Rockbox
I was aware of the fact that Rockbox's firmware reduces battery life before I installed it. I could live with 10hrs battery life. But lately my sansa's e250 behaviour is really weird. I was charging the player for whole night cos the battery was depleted. After charging it for at least 8 hrs the indicator said that it is only 64% full. I didn't trust RB's indicator so I checked at original FW and it also showed that only 3/5 of the battery is full. Has battery gone bad? I srsly doubt that because the player is only 4 months old. What else could be wrong with it?
Thank you for your help.
