1500MaH battery is shiiping

[Polen]

mAh stands for Milliamp Hour, a technical term for how much power a particular battery will hold.

So let's say that you phone uses 500 mA(Milliamp), not to say it does, but just as an example.

so 1500 mAh divided by 500 mA = 3 hours
and 2200 mAh divided by 500 mA = 4.4 hours

Bigger the number longer lasting power.

That 2200 mAh battery makes you replace the cover to fit it, so your phone is fater.
