Mobile phones are power hungry beasts and once the battery starts to lose the ability to charge fully, you start to notice the phone needs more charging. Using an old phone battery will probably mean it won''t hold a full charge but even at 80% capacity the battery will still be able to do most things you want it to. 3. Li-ion batteries are
