bonnie stays at the door for WAY to long in night 4, between her and freddie its nearly impossible to not lose all electricity before you reach 6am without just getting lucky

Your best bet, is to last your power until a little after 5am. By doing so, even if you run out of power, and freddy is going to jumpscare you, you have a chance to clutch and get to 6 am before she can jumpscare you. So utilize your power to try and save it until atleast 5 am, and maybe it might help.
