Dead battery

I think the fixed bug the wiki refers to is a state where the phone 
would discharge the battery while plugged into a charger...

The unbootable state is a known hardware bug.  I don't think leaving it 
plugged in and turned off will help.  It might even drain the battery 
further.  I think they're working on getting it to boot without a 
battery, which will solve the problem.

Shouldn't the qtopia image have seen that the charge was below, say 5%, 
and shut itself off?  Does / should that logic live in the kernel, or in 
a userspace daemon?  What about third party batteries (that don't report 
% charge)?
