My PSP has recently been suffering from battery issues. When it runs on battery power, it acts like it can barely connect with the battery. I works just fine for a few minuets and then the battery icon in the XMB keeps disappearing and reappearing. Also some homebrew applications display -2,000,000 or so volts on the battery. It also randomly shuts of as though I removed the battery.
It works well enough when it’s charging the battery or there is no battery and the AC adaptor is connected. But when the battery is done charging it goes back to screwing up. I don’t think it’s the battery, as I have 3 PSPs and batteries, and this one psp acts the same with all three batteries. Also none of the other PSPs act this way with any of the batteries.
This started a little after I upgraded from 2.71SE to 3.02OE, but I don’t think it’s a firmware issue. I installed 3.03OE-B and went down to 1.5 and it still does it. I reinstalled 3.03 OE-B and that didn't help either.
If anyone has an idea of what could be wrong or what I could do to possibly fix it please tell me.
edit: Also once it shuts off, I have to remove the battery and reinsert it to get it to turn back on.
