I'm going to do several tests on my DS which will show the amount of battery life it has while playing on the CycloDS. I just did one recently even though I didn't played it Non-stop. I however, kept track how many hours, minutes I had played. Also let me reassure you that I didn't touch my DS until the following date, which was fully charged at that time. Here's Test 1 so far...
