#Quick #Charge #Explained
You waited till the end to say 3.0 charging phones won’t be out till 2016 and it is now 2019? I have a Galaxy S9 plus. Does it have Quick Charge 3.0? Also, you mentioned needing to buy a quality cable to use 3.0, but you didn’t say what qualifies as a quality cable for 3.0 charging!
Old but still actual video!
One thing — the cable quality is not so important for Qualcomm’s Quick Charge, because it maxes out at 2A(even 1,67A in higher voltages, as you pointed out). And most cables support that kind of current.
Huawei’s SuperCharge uses 5A of current, so if the cable is not original(and VERY thick) it can’t work.
BS if you charge at anything more then 6V your phone will shut off charging. But you can charge at 5v 4a .
it is years late but in order this “quickcharge” to works we need :
1.) A Smartphone capable of certain quickcharge (2.0/3.0)
2.) A Powerbank capable to deliver quickcharge
3.) A cable that also supports certain quickcharge <–???
are those correct?
(P.S.: how do you re-quickcharge a powerbank ?)
The talk about a good cable at 7:59-8:01 is OK, but “volts of current” indicates no concept of how electricity even works. Amps alone pushed through a wire is what determines the diameter of the conductor needed.
USB is 5 volts. The reason it QuickCharge needs to find a charger that is 3.0, is because it wants to supply the same amps or less across the same cable at voltages that are far above normal USB. If they find each other, the smart charger needs to be able to shift to supply it. If there is not request from the phone or response from the charger, it doesn’t happen, and everything stays at 5 volts. If it does find it, it can take the same current across, and then if taken across at 20v, multiply the current times 4 to charge the battery with. Version 3.0 can indeed ask for down to 3.2 volts, but a normally charged Li-Ion battery is 3.7 volts. With intelligence like that, it MAY also be better at keeping your battery from overcharging overnight and shortening the battery life but I have not found anywhere where Qualcomm has committed to this. It also adjust based on battery temperature.
Not of this matters today because the newer phones now come with USB-PD (USB Power Delivery) Google/Android didn’t want to favor Qualcomm or any other vendor. USB-PD is very much like Qualcomm 3.0 except it is implemented at the USB hardware level. This means it doesn’t matter which processor the phone uses, making the same technology work across any processor on any phone it is implemented on. I have found no place where USB-PD commits to not overcharging either.
So, it may be that fast charging does theoretically reduce battery life to some degree, but intelligent charging probably makes that up and more. If these intelligent charging systems are intelligent enough to cut it off when the phone is fully charged after you plug it in at night, it is far more likely that it extends battery life due to its intelligence. Your phone knows when to tell you to disconnect the charging with a regular charger, so IMO it would make sense they could inform an intelligent charging system to stop charging until the voltage bleeds down from 4.2 to 4.0 before it allowed a trickle again. The scenario affecting battery life the most is charging after the battery is at 100% because unused energy turns into gassing, metal-plating, and heat.
Can i charge my qualcomm quick charge 2.0 supported device with 3.0 supported charger??
My phone came out in 2019, but it uses Qualqualm Quick Charge 3.0.
I got a S10+. Does it support QC 3.0? I would imagine it would.….right? The charger I just got has Qualcomm 3.0 port and a IQ charge port.
8:00
Volts of… *current*?!
Hopefully, Mehdi from ElectroBoom does not watch this.
Thank you mate
i wonder about my lenovo p2. it doesnt have qc 3.0 or anything but it had the quick charge feature. how come?
can u explain OppO vooc charge
QC 3.0 sucks. It can charge the phone between 3.2 to 20v. But it has to be convert the volt down to 5v inside the phone. So it waste a lot of energy and heats up the phone internally. Oneplus warp charge 30t instead pushes 6000mah and doesn’t heat up the phone because it’s always 5v. My Nokia 7 plus often overheat and restart thanks to QC 3.0. especially when using it during fast charge.
is it ok to keep your phone charged continuously even when its full for quick charge 3
Ok so I have a generic power pack 24000mah [91.7wh] . I want to be able to charge this pack as quick as possible. I have a wall charger that says 9.0v 1.67 or 5.0v 2.0a and just a generic standard cable. So what do I need to charge this pack asap . Thank you
I’m watching this in 2020 as I only got a fast charging phone now and it’s still as relevant as it might’ve been 4 years ago.
Dont forget the type of cable !!!

Thanks for detail explanation
hii.. I know that battery model diagram is internal resistor. so to charge faster you need higher ampere, which you can get by higher voltage… (as I know, battery is charged by Amp and not by Volt). how can you charge faster with 9 Volt/1.67Amp? is there a DC to DC inside the smartphone to change the 9Volt/1.67Amp to 5Volt/3Amp?
Wat
Hello what’s the difference between a Quickcharge 3.0 and an 18W PD Fast Charger?
So a phone that can only charge at one amp can use a charger capable of delivering two amps because the phone will only pull the one amp it needs?
And qc3 works by communicating with a qc3 compatible phone so the charger can know exactly how much power the phone needs and thereby avoid delivering excess power that would cause the phone to overheat?
So Qualcomm invented qc to create a problem that didn’t exist previously (phones overheating by chargers delivering too much power,) while simultaneously using the same technology to solve the problem they just created?
I’m currently using the first qc compatible phone I’ve ever had, and it is a nice feature that it doubles as a hot plate. Thanks, Qualcomm! Fortunately linus tech tips has a video about water-cooling phones.
Now this video gave me the info I needed on understanding the 3.0. thank you very much
hmmm it did not tell me where to plug phone or how to plug phone not charging
Thank you, very well explained. This technology is quite clever apparently
Well my wife and I overcame this problem years ago. I used the information I was learned growing up and soled the problem. So I will tell you how we did it.
I just purchased 2 more batteries and each of us carried a fully charged battery in case we needed it.
Do we really need to keep following what the industry is telling us to do or do we just use comin sense?.
But my phone is not fast charging,is it still safe?
Does quickcharge 3.0 work on a micro b phone? Micro b is basically the standard for old phones, and only semi newer ones are using the micro C. Do I need a special cord?
These days… switch mode power supplies don’t try to get rid of excessive power by heating up . .. the get hit because of the amp draw. That’s it
You’re way behind my man. We’re talking about nano2 technology now gan technology now and you’re back in the future. Come on catch up brother or your channel is going to be irrelevant very soon. I just got a nice battery for $33 which is a 45 w PPS it’s going to handle my S21 supercharged catch up my man catch up
I feel it is a total scam
Cocaines a helleva drug…😳
Great video
Fantastic explanation. Just got an S21 and a 3.0 charger. I noticed I tried to use the new 3.0 but my phone was already at 100% and it was not taking a charge. I didn’t realize it wasn’t taking a charge because it was at 100% And I figure that’s why so I’ll try it when the phone gets down low
Good details!
thank you cook somebody keep going to scare somebody talked about going to blow up or something thank you so much you helped a lot ❤️💕
well done!
Manufactures are not trying to solve anything but how to keep the $$ flowing in. I can’t wait till they claim we NEED a KW charger for 3000 mah battery.
What happen if I want to power a 9V device with a QC USB port ? Is it possible ?
Love it! Very informative. Great presentation
Except for quick charge pro in a real products review test the rest are just cheap knocks. I paid 30 plus dollars for quick charge 3.0 model 44–32 and it was a piece of junk. It charged at the same length of time as my regular charger and now after a year or so stop working completely
I bought two, doesn’t work. Contacted the vendor and they sent me replacements but they don’t work either!
I think Pewds is transforming into an angry Italian chef. The
It’s gotta be a real potato laptop from early 2000’s to be having USB1 that’s charging at 0.5A and that’s probably not correct way of comparison because really 99% of laptops in circulation in use today around the world would charge with USB 2 or USB 3 which is above 2A anyway.
how about 3.0 and 3.1amp too?
