The Trouble with Super fast Chargers

 I desire every other day we see other company boosting about how briskly their new smartphone can charge but what tons of those companies don't tell you is that faster charging doesn't come for free of charge so very quickly the way your battery works is with two poles a negative and a positive at the negative end you have plenty of free electrons at the positive end you've got less so naturally those electrons just want to be due that negative end to the positive and along the way they will power whatever components you set in their path once they've all flowed your battery is dead and that is where charging comes in we will use electricity to basically push electrons back to the negative side creating that difference again then really all folks charger is doing is pushing those electrons back faster but there are some problems to the present for starters it means in any given amount of space you really get

1. Less battery capacity

In every battery between that positive and negative pole you furthermore may need a separator it's there to form sure that the electrons don't just go straight from one side of the battery to the opposite which they really undergo the circuit that you simply want them to but see the faster you would like to charge your battery the thicker you have to form this separator to stay the battery stable then the particular amount of usable battery you've got the battery density falls and if you would like to charge ultra fast like a lot of these new phones are starting to do you've got to take this a step further and also split the battery itself into two separate batteries which as you'll probably guess wastes even more room this is often why you just about never see ultra fast charging on anything but big phones because it takes up so much room.

2. Heating

faster electron movement which generally speaking creates more heat and warmth isn't a battery's ally it can slowly and subtly change its body which can make its ability to carry charge go over time as a really rough estimate albeit you kept your battery at 30 degrees Celsius you'll expect to lose 20 percent of your battery capacity over a year and if you kept it at 40 degrees celsius something like 40 could just disappear this is often why it's recommended that when your phone is charging, try to leave it alone it's already going to be warm from the charging using it is only going to add to that you might have seen some gaming phones recently which have USB-C ports positioned to be ready to charge while gaming. The only one exception is that if you are going to use bypass charging which basically just forces your charger to power the components of your phone directly and not touch the battery so your battery percentage wouldn't go up but it also wouldn't go down i know Asus has this on their ROG phone 5 .

For example this potential heat damage to the battery is also one of the many reasons that wireless charging kind of sucks if you have the option to charge your phone with a 30 watt wired charger or a 30 watt wireless charger the wired one is that the thanks to go. Wireless will spend more energy and every one that extra energy finishes up has is heat also tons of wireless chargers just promote themselves as how to always keep yourself topped up at 100but actually this is the exact opposite of what's good for your phone so you remember how when the battery's full we've basically pushed all of these electrons in order that they're sitting within the negative pole and when your battery's empty how all of them be sitting within the positive well due to this both 100 and 0 percent charge are literally the 2 most imbalanced and high states to go away your battery in in a perfect world you'd constantly keep your battery at 50percentwhere the free electrons are evenly distributed between both the negative and therefore the positive you would possibly notice that once you next go get a replacement phone and power it on for the first time that the company you bought it from will have pre-charged it to something close to 50 percent because they know that it's gonna be sitting on store shelves for a short time and this is often the thanks to get the smallest amount battery degradation

3. Diminishing issue with fast charging

You'll notice whenever manufacturers quote how fast their charges are they'll always use the starting figure how fast can it charge the first 50% for example. Well that's because the wattage you get given isn't actually the wattage that your phone will constantly be charging at it's just the utmost it can reach and it'll reach that maximum somewhere during that early part of charging as your battery starts to get full no matter how powerful your early charging is, you have to drastically slowdown to protect the battery's health and as a result a 60 watt charger is not twice as fast as a 30 watt charger and a 120 watt charger is not even close to twice as fast as a 60 watt charger so fast charging does through some avenue or another mean you're going to get less battery as you use your phone and this is often why some companies are integrating the choice to slow charge even marketing it as a feature.

I'd say something like 25-30 watt charging is roughly what you need to give you speed but also keep the heat relatively low and allow you to have a large high density battery besides taking place this route of getting a high capacity battery will naturally speed up your charging
