Is it just my DS Lite or does the battery performance really suck? I'm getting nowehere near the official Specifications: I usually play at level 2 and get about 6-7 hours worth. Comparing this too my DS Fatty, which I could play around 12-14 hours, this really sucks. Also standby function, which the DS Fatty could do for 2-3 days, has been reduced to 1 day maximum... So is my DS Lite('s battery) faulty? Or are more people experiencing this?
