[General Questions and Answers] MotoDefier:
I am an electrician by trade so here's the Skippy on 1 amp vs 2 amps. The problem is not that you have a charger that will supply twice the amperage of your standard charger the maximum charging voltage of lithium-ion batteries is actually 4.2 volts and this is why they have a micro processor circuit that prevents applying over voltage to the battery. when you hear of a phone exploding it is because this circuit has failed and has allowed the battery to charge at a higher voltage than can be accepted by the lithium compoud. the problem actually lies in the lithium-ion battery, lithium-ion batteries provide a deeper cycle than other technologies providing longer battery life and a uniform output of voltage throughout the discharge cycle, which is why they are the go to technology for power hungry smartphones. what happens when you serve 2 amps of power to a device that is designed to charge at 1 amp or 1.5 amp is that the ion particles move faster, this creates more heat, heat is the enemy of lithium-ion batteries, the hotter it gets the faster the particles move and the faster the particles move the hotter it gets degrading the depth of charge and causing the lithium an already unstable element to become more unstable much like a nuclear reactor can run away when its cooling facilities fail. Two common misconceptions of higher amp chargers are.

1. If you use a two amp charger your phone will charge faster and faster is better right? (In all actuality if your phone does charge faster on a two amp charger its because the manufacturer provided your kernel or the batteries micro chip protection circuit with a driver or "charger profile" for a 2 amp charge cycle even though they ship it with a 1 amp or some other variant slightly less than two amps to prolong the life of the battery saving them money on warranty claims.)

2. If you use a 2 amp charger it is automatically serving 2 amps to the device, this is only true if the device or the battery has a driver or "charger profile" that accepts the use of 2 amps, (think of it this way, you can go to a restaurant that promises they are able to serve 2,000 lbs of steak a night, you will not be served 2,000 lbs of steak unless you request it. This is how electricity works, while a source may be able to serve 200 amps it only serves what is being requested for. This is how the power company is able to meter how many kilowatt-hours of power you consume in your home, if your home was always being served 200 amps regardless of what you were actually using your electricity bill would always be the same.)

The best thing to do is to allow your phone to charge completely before you go to bed, and unplug it for the night, the reason being is as your battery charges it creates more resistance (ohms or kilo-ohms) against the power source, resistance also causes heat, and because our chargers don't actually have a sensing circuit in them to tell when the battery is full the charger continues to send power at a much slower rate because of the resistance instead of shutting the power off and testing at a set interval to restore power to the cable to recharge any discharge that has happened during the power off cycle, you should also never leave you phone in a hot car while charging, or even powered on. If you have to leave your phone in the car for a prolonged period of time turn it off and do not leave it plugged into your charger, this will ensure that the battery is not in a discharge cycle while being heated. If your a heavy gamer with your device give your device a little time to breath when it gets hot and starts to die, placing a battery into a charge cycle while hot will substantially shorten the life of your battery, remember your device does not have active cooling like a pc so it relies on the user to recognize signs of over heating (most newer phones actually have a threshold warning, which is a little too generous on when you should actually give it a rest) and to make the decision to start closing apps, and to place it on a cool hard surface that will help the device disipate heat, once your device has cooled to the touch you can then confidently plug it in for a charge without fearing a fair percentage of charge depth loss. Overall lithium-ion batteries are one of the most fickle technologies of power storage, but when treated properly definitely give you more bang for your buck.
