Smartphones today not only offer its users large capacity batteries or power-saving optimizations, some also offer fast charging so you could get as much power to last you through the day from the short while that you charge your handset. Fast-charging technologies are offered by different companies. Introduction to Fast-Charging Before we begin, let's first understand the simple 2-part process of fast charging smartphones. Secondly, there are two stages of charging a smartphone battery -- the first stage is done by delivering a high amount of power until the phone reaches 80%. This is the same principle in charging that's why you see companies claim that their phones can be charged up to 80% in just so-and-so minutes. For a background on its technology, it uses an Intelligent Negotiation for Optimum Voltage (INOV) which is basically an algorithm that allows the device to 'determine what power level to request at any point in time.' This enables the optimum power transfer and maximizes efficiency in charging. Qualcomm Quick Charge 4 The latest and most advanced quick-charging technology from Qualcomm is the QC 4. It aims to extend smartphone use by five or more hours with only five minutes of charging.
