    Default Optimal charger amperage

    So I wonder who in this forum is the electrical engineer to ask. I want to use a charger with a higher rated amperage than the 1.0 Amp charger that came with the phone to speed up the charger. I have used a 1.8 and a 2.0. The 2.0 I worry it's over stressing the device as it gets pretty hot. Anyone one know what's a "safe" charger to use besides the stock 1.0 Amp? Thanks.

    It should be okay but don't hold me to that. Lol. I say that because VZW sells a rapid charger for the DNA that is 2.1 Amps & I seriously hope they wouldn't sell an accessory that would damage our device.

    Amps don't matter, Volts do. The device will only take up to the amount of Amps it can handle. By using a high Amp charger you are potentially unlocking 'faster speed' charging. Part of the reason the old Samsung phones charged so slow was a crazy small power supply.

    Don't worry, you'll be fine.

    Does a faster charge drain faster than the slow charge?

    No. As long as all the energy gets put into the battery, it's as full as it would be on a slow charge. Think of it like filling a bucket from a 1" diameter hose vs a 1/2" diameter hose with the same pressure behind it. The 1" will fill it much faster, but full with a 1" is the same as full with a 1/2". It just takes longer to get there.

    The phone charges faster than other phones . Qualcomm has quick charge 1.0 on the snapdragons4s. So if u have a phone with a similar processor it will charge faster than something that doesn't have the processor
