how do you turn the blacklight down, when i try i can jus turn it down to 30seconds, but it might be cuz i overcharged it, didnt no u could do that....it jus goes down 2 half the battery life, like real fast... and when i charge it, it charges for a little bit, hour or so.. and ti says its full and dont charge anymore, even if the battery was like 1/4 left
