I'll be quick.
1) when to charge my iPad 2? (10% 20% ...)?
2) what is full charge cycle?
A - charge to 100 from X and then discharge to 0
B - discharge from X to 0 and then charge to 100
C - discharge from 100 to 0 and then charge from 0 to 100
D - ???
3) is that bad to charge my iPad only to 80% and then taking it for use?
4) is that bad to use my iPad when battery meter is red?
