one thing I've noticed as a reviewer at the verge is the problem surrounding smartphone batteries regardless of which next-gen battery technology you're using lithium-ion batteries tend to just die during the day anyways besides can't come up with better battery technology it can at least change how quickly we charge our batteries USBC for Android phones and the lightning cable for iPhones are not capable of delivering hours of battery life with minutes of charging it makes life easier if you're running the meetings and don't want to carry around battery packs but just how fast can we charge our phones not just presently but how fast can fester can get in the future so before we get into fast charging let's take a refresher course volts amps and watts let's look at it like this volts represent the amount of electricity available in your wall outlet the current or amperage is controlled using your charging brick and is the rate at which electricity travels and finally the watts are the total electrical power that gets into your phone this means that watts are the products of volts and amps vaults times amps equals watts in order to charge our battery we can increase the Volt's and charge it faster if we increase the amperage we could also occur the battery faster and if we increased both we can drastically increase the power going into the battery the thing you need to remember about any energy transfer is resistance the byproduct which is Heat excessive heat for batteries as we know is really really bad historically most USB chargers range from 5 to 12 watts but they weren't able to charge fast and stay cool today USBC has come a long way it supports up to 100 watts charging times set by the manufacturers and supports a wide variety of devices to make sure that the battery doesn't overheat OAM is a Qualcomm and Apple install devices called charge controllers they regulate electricity going into the device and make sure that they don't over fall or overcharge and thus keep the battery safe and cool for example if I use a hundred watt power brick to charge my macbook pro it'll use the full hundred watts that's what it's supposed to do but then if I put that same charger into my phone the charge controller will transfer the most power it can use before davic is the bad around 29 watts or so all fast-charging standards like 1 + s - charge apples fast charge or Qualcomm quick charge basically do the same thing they charge your battery safely quickly and they make sure that doesn't overheat while it's doing so okay so what's fast charging performance like nowadays well the fastest way to charge your phone is with the cables out of the box Android phones like galaxies pixels oneplus devices or LG phones should come with fast charger setups but with Apple you'll need to buy a USB power delivery break and USB see the lightning cable that will allow you to charge an iPhone 10 from 0 to 50% in 30 minutes that's pretty good but what sort of performance improvement are we gonna see in the next couple years unfortunately not much there is one concept that could allow us to charge our phones a matter of seconds and it's called a super capacitor electrons make an electrical field which allows them to travel much faster the problem is though again overheating but that's all theoretical back to reality Qualcomm is working on the next fast charging tech called quick charge for plus it's actually available on a couple phones right now but not many quick charge for plus aims to not only regulate heat better from the conductor's but also charge the phone even faster in fact Qualcomm designed a reference smartphone which can charge from zero to 50 percent in just 15 minutes which is pretty fast your next flagship smartphone is probably gonna be using quick charge for plus and get closer to those numbers and while those numbers are an instant well at least your phones will blow up thanks for watching and remember not to use off-brand or cheap cables for fast charging because they can really mess up your phone in your battery and if you want to hear more about batteries head on over to Virg science
