Fast charging: Explained.

 

Introduction:

            With phones backing in of the core CPUs, and 4k displays, there's only so much smartphone battery can handle it. Now one way to improve battery life would be to stop in a bigger battery. However, that's not exactly a solution. Quick charging or fast charging is one such stopgap method, that manufacturers are implementing to buy Sai until a new battery technology comes along.

Quick Charging:

            Quick charging is a technology, originally developed by Qualcomm which involves pumping a phone's battery with high power till it reaches about 50% and then trickles charging it the rest of the way. Now, this technology is also licensed to other OEMs like ISSU, Samsung, or Motorola to name a few, who then go on to add their own marketing names like saying Turbo Power or adapter fast charging. Now even though, the names might be different. The underlying technology is essentially the same thing. So technically, you could use a Motorola charger on the Samsung phone and still have quick charging. For a quick charge to work, you're going to need two main things. First of all, you need a compatible power adapter, and, secondly, you also need a smartphone with the necessary electrical circuitry onboard to deliver that high power to the battery. Now even though your phone might not be powered by a Qualcomm chipset, it can still support a quick charge.

Power:           

            Most current generation smartphones are compatible with Qualcomm quick charge 2.0 technology. These come bundled with a type aired after which is rated at 5, 9, or 12 volts. However, there's also a tight B adapter that's rated at 20 volts. So, how exactly is the final power output determined? Now take, for instance, your typical A USB port on your PC which is rated at 5 volts at 0.5 amperes which gives you a total power output of around 2.5 watts. Similarly, a Samsung Galaxy Note 4 power adapter is rated at 9 volts at one point six amperes giving you a total power output of fourteen point four watts. This is a lot more power than what you would get from a USB port. This is why it can charge the phone a lot quicker.

            Recent USB type-c smartphones like the Nexus 5x and the Nexus 6p also support fast charging but why an industry-standard rather than Qualcomm technology? This is why Qualcomm quick charge adapters might not always work well with these smartphones. Now, we should see smartphones equipped with Qualcomm switches 3.0 technology. This new version allows for faster charging times but more importantly. It also adds support for granular voltage scaling. This means that your smartphone will be able to ask for the precise amount OFM power needed, thereby avoiding excessive power wastage and unnecessary overheating.

 

 

Stay tuned.
