Question

Why do phone batteries seem to lose charge faster when they are fully charged, while they can last for an hour or longer on 1%?

Answer 1

It is a psychological tactic employed by phone companies(and pretty much every other company that uses a rechargeable battery). They report the battery status relatively accurate until about 33%, and then the software manipulates the reading so that the final 1/3 takes much longer, even though the battery has much more charge.
