Not all chargers are created equal, either. So go find that charging brick and plug your phone into a wall outlet instead. As we mentioned in our guide to troubleshooting a phone that won’t charge, the USB ports on your PC will charge your phone, but may be rated for only 0.5 amps, compared to the one-amp (or higher) charger that came with your phone. Your laptop may be close by, but if you want to charge your phone as fast as possible, you’ll want to plug it into a wall outlet. Here are some guidelines to follow to charge your phone as fast as possible. Some chargers supply more voltage or amperage than others, meaning they will charge your phone faster (as long as your phone supports it - it will draw only as much power as it knows it can handle). If you remember your high school physics, electricity is measured in watts, which is a product of voltage (in number of volts) and current (in number of amps). Thankfully, you can charge your phone faster … if you can separate truth from myth.

You’re about to head out the door, but your phone desperately needs some extra juice before you leave.
