I just did a crazy thing. I set my power supply to 3.6v and connected negative to the shielding and positive to the positive terminal. The I turned the phone on and the Nokia logo appeared. But then a black screen and nothing more. I decided put the battery back in but now it doesn't want to turn on. No even the indicator LED. I think I killed it. Is there some fuse I can check or something else. I did this just to see how much current the phone draws.
