Okay, so it seems like every many months a new company, someone comes out with a new, fastest ever charging smartphone. Times agone, the flagship iPhone was charging at five watts, and that was fairly standard. also when the Pixel 1 came out, that was super presto,charging at 18 watts. also soon the iPhone banged up to 20. also you might flash back OnePlus beat out everybody for a couple times with 30 watts. But soon we had 45, 65, 80. Now moment, right now, this Xiaomi 12 Pro vessels with this 120 watt bowl. You can buy this right now, moment. It charges the whole phone from zero to 100 in 17 twinkles. And also just a many weeks ago, OPPO demoed this. It's not on a real smartphone yet, but it would charge a theoretical 240 watts,which would go from zero to 100 in nine twinkles. That is enough ridiculous And also as you may have noticed, like I have, enough much anytime one of these demonstrations gets posted nearly, widely the commentary across the That surely is gon na heat. Good luck plugging that in for further than five twinkles before it explodes." People across the board are widely convinced that there's no way that this can be good for your smartphone's battery. Which got me allowing, if this is true, also why would these companies keep doing this? Is presto charging actually ruining your battery? plenitude of Google quests, plenitude of papers read, plenitude of people talked to, and plenitude of hot takes out there, but this is what I set up. Batteries have bettered in their chemistry over time, but right now all phones use lithium ion or lithium polymer batteries. And the way they work is they've a positive side and a negative side. And the lithium ions flow from the negative to the positive side through a liquid electrolyte result. That is what is keeping the phone powered by the battery. When that inflow is over however, the battery has reached 0 and is dead. So charging the battery back over is moving those ions back through from the positive to the negative side through that electrolyte result. The first thing to know about charging a battery is batteries are kind of like a sponger. They absorb the most energy when they've the least in them. And also as they get near and near to full, they can not absorb relatively as efficiently and also there's some redundant lost. With a sponger, it's just redundant water passing through. With a battery, that is just redundant heat. And so what that looks like is charging actually happens on a wind. Those figures that you keep seeing with the 100 watts and 150 watt fast charging, that's not the constant rate of charging. That is just the peak, the outside that they are able of. But that is generally only compactly the factual rate. So a 65 watt fast bowl, for illustration, will generally only hit 65 watts for the first many twinkles, enough beforehand on in the charge from low battery, and also taper off and principally only teardrop charge at a lower wattage after around 80 And you can actually view that if you get one of these incredibly cerebral lines with the display on it that lets you see exactly how important power your phone is accepting while you are charging. I will link one of them below the suchlike button. But also the alternate thing to know is batteries do degrade over time. The iPhone, as you've presumably seen, lets you literally fantasize it, shows you the chance. So if you go to settings and battery and battery health, you can see your iPhone's declination standing as a number from one to 100. So this 13 Pro I have been using is still good for 97 of the capacity it had when I got it five months agone So why does it And turns out there are several effects that degrade batteries. I mean these are picky little effects. They are veritably energy thick little storehouse units. They do not like being at 100 exactly. They do not like being at 0. And they do naturally degrade over time as they go through charge cycles and the ions pass through that electrolyte result over and over again, sluggishly breaking it down. This is completely natural and can not really be avoided as you charge the phone more and more. But the number one factor that damages batteries, that degrades them briskly than normal, what ruins your battery is heat. The ions are moving through that electrolyte a lot, but you can suppose of the electrolyte principally like mariners. They can be enough sensitive to changes in heat. They can actually solidify and clog up the anodes and cathodes, which stops them from being suitable to store the lithium ions. And like I mentioned before, when the battery isn't in the optimal state of charge, it's less effective, and that redundant runoff energy manifests as heat, and heat is no good. So easily the thing then's to minimize any redundant heat around that battery, which would damage it briskly than normal. Now the thing is, generally the more wattage, the further power you are pumping into this battery, the further heat it's going to induce. So it sounds like this redundant fast charging is easily bad for your phone. It's further heat generated and it's bad declination. But that is not commodity these companies are not allowing about. Over the times a bunch of these different smartphone companies have principally been working on trying to figure out how to charge these phones as presto as possible without generating any redundant heat. If you look just Xiaomi's runner for their fast charging alone, there is tons of maps and graphs and claims about what they are doing to get around this. One new advancement came from OnePlus when they dropped that Warp Charge 30T bowl. It was kind of intriguing and a little confusing perhaps that we had Warp Charge 30 and Warp Charge 30T and both were 30 watts, but 30T was briskly. But this was because with 30T, the power operation got handled in the slipup rather of in the phone, so there was further heat produced by the slipup in the wall rather of on the phone near the battery. So OnePlus could put the same quantum of power into the phone but for a longer period of time without hotting it up as much. And so the charging wind could be bettered like this. So that is a nice step.The strike there's now we are getting larger power bricks, but that is a bit of a trade off people are willing to make, I guess. But also another way we have seen a bunch of companies jump on, especially recently, is with commodity called resemblant charging. principally, rather of putting a ton of power into a single battery, they actually resolve up the battery into two cells next to each other and also add power operation tackle to resolve the incoming power. This is a simple but brilliant way to get briskly charging times without a ton of heat. Imagine rather of trying to pump 50 watts into a single,000 milliampere- hour battery, just doing 25 watts into two batteries of half the size. That is gon na induce way lower heat, it's only 25 watts, but combined, when you draw the angles, you can achieve the fellow of 50 watt charging and you get to put 50 watts on the box but it's with way less heat. But again, there is a strike to this system too, which is a slightly lower overall battery capacity. Because if you take the same internal volume of two batteries rather of one, that means there i further space taken up by the boundary between the batteries and the casing and that charging operation tackle I mentioned. So you will frequently end up with slightly lower overall batteries if they are resolve like this. And also of course, commodity we have seen in just about every new phone coming out which does not really have a strike is just adding further cooling tackle onto the phone itself. occasionally that is heat securities and vapor chambers. occasionally it's a whole addict. But specifically, we are trying to get the corridor inside from getting too hot. It feels like every cell phone advertisement for the once two to three times has some kind of section about cooling, especially gaming phones. You're, of course, cooling the system on a chip, too, but the better the cooling system overall, the further power you can put into the phone without it getting too hot. Is it that simple? As long as you keep the phone cool enoug you can put as important power into it as you want? Well, there are the downsides I mentioned before with the larger slipup and perhaps the phone's got ta be thicker with further cooling and has a lower capacity battery, but the question we are trying to ask is what counts as ruining your battery? That is a simple one, and it turns out there's actually an assiduity standard for this. From the exploration I have done and the people at these companies I have talked to, the generally accepted target thing is 80 battery health after 800 charges. So let's say you charge your phone roughly formerly a day. That'll dis out to about two times. So 80 charge after two times. This iPhone, now that I am at 97 after about five months, is on track to be at roughly 85 after two times, which that is enough good. That is above the assiduity standard officially not being ruined. Now, for all these super fast charges that are new, well, it's tough,'cause they are new.They have just come out and we do not have long- term data. So I am principally taking their word for it that, yeah, the fast charging does not ruin the phone over time, but it's the stylish information we have and it's actually unexpectedly emotional. From their test results, Xiaomi on their point say that their 120 watt charging tech is rated to maintain 80 battery health after 800 charge cycles. Apple on their point, they do not have the fastest charging, but they say 80 after just 500 charges. But like I said, it seems like they are outperforming their own claims, hey, under pledge, over deliver. And also OPPO and OnePlus, who've blazoned they'll have a 150 watt charging phone this time, say that they have specifically stated it will go 80 battery health after,600 cycles. So that will outperform the assiduity standard, which I guess means they've room to keep going up. Now do not get me wrong, the trade offs are veritably real. Not everybody wants a thicker phone or a larger power slipup or a slightly lower capacity battery, but from where I am sitting and from the test results that we can go by, principally, fast charging does not have to ruin your battery life And really the stylish part of that's just convenience. On top of the fact that these companies are all laboriously still working on making this stuff more. You might have heard about gallium nitride dishes. There is a couple actually out there formerly in the request. That allows the slipup to actually be much lower than the typical silicon dishes we are all using now. So you can do a 65 watt gallium nitride bowl half the size and still put the same power into the phone. Batteries these days are smart. ultramodern phones all have tons of tackle and detectors inside the phone to help measure temperature and regulate charging. So it's doing all kinds of stuff automatically And also the phones all will add a bunch of software features on top to help you laboriously maintain the battery to the utmost degree. Plus, phones like the ROG Phone 5 have pass- through charging. So when you are plugged in, and gaming, which is generally not a good idea on a regular phone, it can just power the system and it does not add charge to the battery at all. So you are not putting redundant stress and heat on the battery and it can maintain battery health for a lot longer. The rearmost iPhones and Pixels too right now have a point where if you plug in at night around the same time every night, after a many days it learns when you wake up. So rather of charging right to 100 when you plug it in, it charges up to 80 also waits all the way until you are about to wake up, perhaps an hour before your alarm, and also charges the rest of the way up to 100 so you wake up with a full battery but better health. And enough much any other phone with this super fast charging coming up is gon na have to have a suite of battery health options that you can mess with in the software to take your battery health protection to the coming position. So I do not know how fast these phones charging is gon na get in the coming couple times. inescapably, it's just gon na keep getting better as the company's work on it. But what I can tell you is the stylish thing we can do for our phones is to just use them like normal and principally do not give them any redundant reason to get hot. Leaving it in the gusto of your auto on a sunny day, gaming while plugged in for long ages of time, stuff like that. still,If you can avoid your phone getting superhot.you're doing the stylish thing you can for your battery And these smartphone companies all know that battery problems are bad news. So if they are all doing their jobs, also we should all be good. Fun fact, the notorious Galaxy Note 7 battery exploding issue, as crazy as it was, it was not actually due to gormandize charging or overheating. It was actually just them with their battery supplier getting some confines wrong and some bending going on of the battery with the positive and negative sides up in the corners. commodity to suppose about. Either way, now you have the answer.Thanks for watching
