I have a fat psp as well as a slim psp and have followed the tutorials on here to install LED mods in the triggers for both. Both work like a charm. I used the sound reaction mod tutorial for the slim to find my power points and wired it to the Wi-Fi switch like it shows in the tutorial so that I can cut them on and off (2 blue SMD LED's with 10 ohm resistor in parallel). I turned the slim on and everything looks great. One big problem though.....ever since I installed it, the battery last only about an hour from a full charge (battery is brand new, never used as pandora). I was wondering if this is normal and if anyone else has had this problem. On the fat psp I have 4 LED's in it (triggers and buttons) and its battery last a few days from a full charge after playing with LED's turned on and it has been used as a pandora battery. This makes no sense to me. I am thinking about removing the LED's from the slim just so I can play it longer than an hour. Any comments or things to check are greatly appreciated. Thanks in advance.
