Android problems slow charge the battery

Had no idea why the android at the moment recharged kok is not full-full, just found out after purchasing a new charge, getting questions from the seller choose which regular or somewhat expensive, I think it is important that the same charge could make rechargeable batteries.

There's a great charge explained it, I forget his name anyway have a high power components make fast charge the battery full, while the cheap components have lower power so as to make the contents of the old battery.

Didn't know this is right or wrong it is also affecting the fast and slow charge the battery voltage i.e. android, when at home with the electrical voltage 900 compared to workplace electric-voltage if not mistaken 3300, at the time of charging the 3300 more quickly, that's what I feel.

So could try android when charging is slow, it is possible chargenya, replace with a good charge.

From my experience, have a lot of faulty charge there on transformer components, the cord is not a problem, so if I can deduce this charge component also affects whether or not fast charge the battery in android.

So hopefully it helps.
