It seems to me the battery may just be incorrectly configured.
I will preface this by saying that I have no idea how battery percentage is read in Android but given the behavior I have seen here are my thoughts.

The battery reports being 100% till the very end of battery life. At the very end it quickly drains. So it seems like the calculation for battery life is something like this x=current amps remaining
y = total amps battery can hold
thus percentage is x/y
my theory is that y is inappropriately reading or set low
so for example when x=500 it is still displaying 100 since y is set to 200

Is there a way to manually set the total amps the battery can hold? If so it seems the battery reporting issue would be solved relatively quickly (and hopefully the charging issue with it)

(Apologize if I butchered the physics on this, it has been a very long time since I did anything with electricity)
