Edit: Its *Edge* not *Internet Explorer* I am sorry
PieRow no shit pls
???
It has nothing to do with Internet Explorer ...
To true! Microsoft edge is the new electron! MICROSOFT IS TAKING OVER!!! AGHHHHAHAH
Thats how yo know it displays slow charging ( ͡° ͜ʖ ͡°)

He got bullied today. Don't talk about it.
shhhss guys. he need some time alone
Seriously, he needs his safe space.
@KeweKrypto 12 sorry hard
I just throw my phone out when the battery dies.
Electric should recycle it instead
No one really recycles their electronics lol I still see people dumping their tube TVs in vacant lots and other electronics.
MuscleMan and amd vegas
Yeah seriously, if I want to recycle my old electronics, I would have to bring it to some "eco center", the nearest being 30 minutes, by car, from here, so F that. If they can't pick them up with our regular recycling(plastic, glass, paper), I ain't wasting my time and money bringing it to them, especially when they make money out of them.

Oh please, I haven't even charged my Nokia 3310 since it came out of the box.
That means your phone is no good anymore as all Smartphone batteries have what is called a Self Destruct circuit in them and after a few years this will activate to stop the battery getting unstable and will render the battery unable to charge meaning the phone would be completely unusable

Bohdan Lvov i was about to just comment that. !!!
We don’t actually give much thought about charging our phone everyday . But actually start wondering about your phone’s battery life just because you couldn’t finish your favorite show or a mission of your favorite game because of your phones battery life.Then your mind attracts those wild thoughts of improving phones battery by stuffing it with a bigger battery or use it while its charging , well come on we all consider these , but these are not the solution to our problem . Don’t worry Fast charging is the only solution. Read more click here wp.me/p9fQhG-ll

The wonders of fission batteries. They literally last for hundreds of years.
Hah true true xD
KastaRules but yet my power armor always runs out of fusion cores
It's a conspiracy of planned obsolescence so that the battery companies can keep selling batteries, even though there's plenty of juice left. In the old Fallout lore, the Power Armor's are said to have an energy source that can last for about a thousand years. You're getting bamboozled!
NurdRage shows you how to make your vary own Portal fission battery. it's not actually as cool as it sounds sadly. but it still follows the science correctly!
question and suggestion: WiFi security is a thing most of us worry about. Can you perhaps explain each security setting on most generic WiFi routers? This will be really helpful because it will allow us to manage the security settings better.
Fast charging is awesome. I can charge my phone to full in about an hour regardless of what level its at. Even if I can only charge for 5 minutes, that can add quite a bit of battery life. Also having a battery pack that does fast charging is sweet too.
Don't go using every night though as it will shorten your phone's battery life
@@stephensnell5707 by the time battery damage matters, the device is ready to be replaced anyway.
How much do you use your phone to need fast charging and a battery bank?
I listen to music/podcasts on Bluetooth all day and my phone survives fine.
I wish this wasn't an excuse to get rid of user replaceable batteries.
lg g5 had quick charge 3.0 and removable battery
Yep. I bought one for a nice discount just before the G6 dropped. The second half of a full charge doesn't seem to take any longer than the first half. It's a great technology and a great phone, imo.
Yeah. My Vibe P1 had no user replaceable batteries but got fast charging. I wonder why...
Any phone battery is replaceable if you make the effort to open your device (unscrewing if necessary).
Simon Tay unscrewing? Ungluing!
This is in my physics exam yeay
Gotta love physics

I was wondering about this last week, thanks! :D

Wat
$50 for a fill-up? HAHAHA! I wish!
Here in the uk its not uncommon to pay triple figures GBP. My VW T5 costs me around £90 (about $120 usd) from a near-empty fillup.
SoulDragonWithFlow In Canada that would be $30 for a fill-up
SoulDragonWithFlow we have higher taxes bro.
I have a 2001 Ford Taurus (I don't think it's available in Europe) that has a fuel capacity of 18 US gallons or ~68 liters. And I thought that $30 to fill up was too much. LOL.
Jose Javier Flores Yeah, well, fuel in Europe is MUCH more expensive than in the US (or pretty much anywhere else). Currently it's around 1.30€ per liter in most countries. The more expensive ones go all the way up to 2€, which is absurd. (2 years ago high octane fuel on a highway in Italy was 2€, normal one was 1.85€).
Filling my tiny Renault Twingo's (1.2l turbo) 40 liter tank costs me over 50€ ... Talk about expensive.
Now you know why we can't have big V8s here ...
SoulDragonWithFlow fuel prices here are absurd! The guy said $50 as ab expensive price for a full tank for a large truck! £50 in the UK would get a half tank for a small petrol engine.
the 5v 4amp example was a bit of a poor choice, amp draw isn't dictated by the charger (other then perhaps a safety limit) it's dictated by the load, in this case the phone.
If you hooked your phone to a 5v 100amp charger, it'd still only pull the current it's designed for (probably less then 2 amps)
Typically when people are talking about fast charging, they are talking about higher voltage charging (yea i know, the phone steps it back down to a lower voltage to charge the single cell lithium battery, but that's not the point)
The fast charger's are usually able to supply voltage higher then 5v, but won't do it unless the phone tells the charger it's ok to do so. The main benefit of using a higher charging voltage is that you don't need to use really thick cable's to charge your phone (wire size needed is dictated by amp draw, not voltage) Once your fast charging phone recieve's this higher voltage it step's it back down to around 5ish volts to charge the battery, but if it steps down from 10, or 20volts to 5, it can change the excess voltage into amps. That's what the watt's are all about, watts are used to describe how much total power a device uses. 20volts at 1 amp is 20 watts, so is 1volt at 20 amps.
All sorts of electronics use this same technique to reduce wire size. Your CPU for instance probably runs on around 1.2 volts, but your power supply doesn't offer it 1.2v, it gives it 12v and there's little converter's directly beside the CPU that change the 12v supply into what your CPU needs (which is very high amperage, a 80wTDP chip is going to use around 60-70 amps) Because the high current only has to go from the converters to the CPU (which is right beside it) you don't need to use huge wires or giant pcb traces. Not only is this nice for packaging and looks reasons, it saves them a lot of money in reduced copper usage.
I use a hauwei ya8 very cheap phone work up today and realized I forgot to charge it
Dressed and off to work, I put it on charge using the company plug and in a space of 20-25 minutes my man was 78% and it's not even an expensive device tec is awesome
phones are easy to open. All you need is a head.
(1)Get your phone on your table
(2)Smash you head into the phone as hard as you can
(3)If you survive then your phone will open, or crack
Nah, just drop your phone 4 feet without the case
1:48 - 1:54 was an interesting and useful stuff to watch !
Thanks nice short informative video answering questions i had
Love this video. Really appreciate if make another video on (1) Whats the difference between fast charge, quick charge? (2) How to choose plug & usb cable?
Idk

I totally forgot Luke was part of LTT haven't seen him in months.
He went over to Floatplane a few months ago, which is "technically" another company (Linus said as much in a WAN Show). This is why he's been mostly gone.
Awesome video!
I have to add that fast-charging in a lower battery charge (about maybe 0 % - 20 %) can eventually damage the battery a tiny little bit (works for all Li-Ion based batteries).
But what kills your battery even faster ist not charging it in time. It gets permanently damaged as it reaches a lower level. In fact, Li-Ion based batteries live by charging and normal-use-discharging. The times of "you have to fully discharge your battery and fully charge it again" are over, this works for your NiMH and NiCd! This is why I recommend airplane mode at about 30 % until getting home (which should not occour a lot of times hopefully, and if it does: avoid it on your next phone/spare battery).
Trust me, I´m a dark wizard,
Greetings!
using airplane mode kinda kills the reason for having a phone
@@DanielQRT it will help a phone to charge 2 to 3x faster
It's about time... Thanks you guys!
This is awesome especially the handshake

Jamezeboyy pretty easy, basically some phone batteries can recive more power (wat) without overheating
I see the light. Thank you internet man.
You turn down 4watt and then you get fast charging. It's under Battery settings.
Jamezeboyy hahaha lol
*woah technology*
Hey Luke! Nice to see that you are actually alive.
With great power comes great responsibility
One time I just fell asleep while watching RUclips and found my phone just dead on the floor
I like how his whole team is Game of Thrones characters.
I was so glad when he said "or more" after suggesting it would cost $50 to fillup a big rig. I only have a 1 ton truck and it costs me about $190 to fill up!
Perhaps you could cover AVX instructions (AVX512 in particular) in a video, it's topical given X299 and it explains at least to a certain extent why Skylake-X especially the 10+ core models heat up like prescott with a fever
Samsung: Mate we can handle fast charging, how about 100w?
Galaxy Note 7: f.
Tunnel bear is so popular that it's even used in westeros 3:42 😂😂.....screw them damn ravens!!
Regarding last slow charging, it's nothing to do with power you supply, it's physics. At 90%, if maximum battery voltage is 4.3v, at this percentage, you are already reached 4.3V and you can't push more current, while when you have 3.5V, charger can push as much current as it can. This is called CC CV charging, at high percentage, it will become CV charging "constant voltage" and current will tapper off.
This would have been useful to know a week ago. I bought cheap wires for my quick charge LG G4, and the phone wouldn't even fully charge overnight. Had to buy cables that specifically say they do quick charging
For those of you plebs without said "fast charge" technology, you can charge your devices quicker than normal by doinga few things:
1. enable power saving, if your os supports it.
2. enable airplane mode, kill any wireless radios.
3. for root users, change the CPU governer to "power saver".
do this while you charge, and use your stock charger to gain about 1-2% per minute to charge. my S5 charges from 15% to 100% in about an hour this way.
another option: turn the damn thing off while you charge it.
LiquidZero or buy oneplus phone
LiquidZero Or you know.. just turning your phone off while you charge it..
Are you talking about a Audi S5 Coupe or something? Jk IK what ur talking about its iPhone 5S ..... Right?
idk why i thought he would say with higher power comes great responsabilities
My g4 came with one of these and love it.
I went from an iphone 5 to a lenovo P2 and the quickcharge is so freaking amazing, the phone charges fully in about 30 minutes, alas that being the same time it takes for my iphone 5 (roughly) but seeing as the battery is 3.15 times bigger in my lenovo p2 that's a huge improvement
Burn the candle in both ends. Its the only way to fly man.
In what way was this relevant?
If you have to ask, I dont have to tell you.
But by any hoot, giving up the longevity of your battery for a faster charge. Its like peeing in your pants isnt it? Have you ever touched your phone after these high amps recharges, it feels hot dosent it? But not as my pants bro! Because its full of pee! Woof!
Olebull93 I don't remember which standard does it, VOOC or Dash or one of those besides Quick Charge, but they put most of the charging circuitry inside the wall wart instead of the phone for exactly that reason, to keep it from getting hot and increase longevity.
We are throwing this one back in the bin.
Peace!
A year later and I still have no idea what is wrong with you
Just before clicking the video, I had low battery warning
PypeR well isn't that a coincidence
Before the video, I got an ad about Oppo's fast charging.
I always charge on a normal 5w charger where charge time doesnt matter. IE overnight etc. But fast charging is great for when you forget to charge overnight or only got an hour between flights etc.
@Techquickie can you explain the science/tech behind fast charging? It's well studied academically that most batteries, including the well-adapted Li-ion ones, fail a lot faster during faster charge-discharge cycles, or deeper cycles (e.g. from 100% to 0%) cycling it too fast also reduces capacity, and reduce energy conversion efficiency. So those fast charging we see on the market, do they use something like a supercap as a buffer? Charge supercap up quickly, then slowly charging up Li-ion from the supercap? Thanks.
Who's watching this while charging their phone with a fast charger?
I just buy a new phone when the battery dies
Buying a replacement battery would be A LOT cheaper
Simon Tay you don't say
You, my friend, are irony challenged :D
GottemLeaning gift me one
Funny because phone don't come pre-charged
1:30 I expected you to say "with higher power, comes higher responsibility" :P

Hi techquickie! I would like to ask you to explain what does AMP mean on certain websites? I saw it randomly on one website it says AMP and it has some bolt for icon that is on the left. Thank you!
lets face it: your videos are just absolutely enjoyable. No doubt about it!

It would be cool If you guys did a video about technology and logistics, like package delivery.
Do y'all have a video explain smart charging power supplies, and how or if they can quick charge multiple devices, or does the overall Amps get limited to say 5A per USB port, or is that 5A shared through each device plugged in?
Amperage? Does he not mean current?
Dash charge actually use about 3.5A, not 4A
Arek R. My dash charger says 4A.
4A
So 87.5% of the power of what he said. Thanks for that, lonelyboy...
Also noticed no extra heat with dash charge compared to fast charge
My Dash charger says 4A but only delivers 3.5. Or I can use a dual 2.1A power suply socket to covert 4.2 int 3.5A so I agree with this statement, Despite all the haters saying otherwise, Likely they haven't actually tested and proven their power supplies like I have...
Good presentation
This is the only person i saw in the entire youtube till now who said'if you like it then like it and if you DISLIKE IT THEN DISLIKE IT'. Your gettin a like from me
current. the word is current. not amperage. current.
i'll allow voltage (emf would be better), but amperage just sounds stupid.

"With higher power, comes higher heat"
-Linus, August 2017
Me: What's fast charging?
Apple user: It's this really cool, new and innovative technology that Apple invented that allows phones to charge at super fast speeds. Since it's so awesome, it costs $80 to be able to use.
Android user: It's a way of charging your phone quickly that's been around for years.
I love how americans complain about paying 50 dollars to gas
Kirina Yuuki Cars are necessary in most of the country so yeah, we are allowed to be upset when prices get high.
Marcus Coster he means that it is very cheap when compared to, for example, most of Europe
vinno97 It doesn't matter because the public transportation is good and reaches basically everywhere. There's also not nearly as much space for having a car, the roads are smaller, population is denser (making smog have a worse effect). You could live in a lot more places in Europe and never need to own a car than you could in the U.S. My other point was, Americans almost certainly buy gas more often than Europeans. So overall there's not much benefit for us. Many people would be happier taking a bus or subway or bike everywhere if possible, for FAR less money per month.
Marcus Coster - You assume everyone lives in a built up area with great public transport which simply isn't the case. It is more densely populated but this just creates more traffic congestion as public transport isn't that great and costs a lot. Most people still need/want a car. The only time public transport works really well is in city centers which is probably the same in america but it's still expensive. If you complain about fuel prices in america why do so many of you drive v8's and v6's. There are smaller cars available but you don't buy them so to complain about fuel prices while driving inefficient cars is pretty stupid. In Europe most own 1l to 2l 4 cylinder cars, even the larger 4x4's tend to have a 4 cylinder larger capacity engine. They're not slow either yet much more economical and can be just as large to transport things.
Every country should take notes from finnish public transportation
Ok ok its just the card you use to travel
How come that while my OnePLus 3 dash charges, the battery temperature doesn't usually exceed 30C, although it's being hit with 3.4A (data according to "Ampere" app)?
Vinxian1 sure, but according to the video, the battery itself produces the heat (being a chemist, I can say this makes sense) and not the circuitry around it...
I have to say that I'm suprised it only reaches 30C, even without the the power circuitry.
But the circuitry is responsible for a lot of the heat, the circuitry is not 100% efficient. Therefore it dissipates power. And that in turn generates heat. especially since the circuitry is in a closed environment
Vinxian1 that's true, but really, I thought the battery alone was responsible for the majority of the heat output. 30C is when it's not used while charging though. It's a little hotter when being used at the same time, but still miles aways from an iPhone or whatever
Hence why I love my OP3T, all round brilliant phone except the camera for a good price and it beasts every other phone charging wise.
Also, you can get an "VOOC" charger block which can usually be found for cheaper and is the same technology in Dash Charge (VOOC is created by OPPO who also own 1+)
because the heat production follows P=I^2*R (power= current squared times resistance). If the internal resistance of the battery is lower, it will output less heat at the same current.
That was the smoothest ad transition ever.
When he said "with higher power, comes higher heat" I would loved if the editor used uncle Ben talking to Peter.
My samsung only came wiht fast charge, what do i do?

For a second there I thought you were charging the phone with the souls of outdated internet explorers...my bad!
I was looking for some more in depth information on the charger and the phone. What does the phone communicate to the charger and visa versa. How does it decide when to charge with 9 volts and when to go back to 5 volt.
Riddle me this batman.. explain why my Samsung wireless fast charger doesn't fast charge as fast as the cord.
asap bruhhh Wireless is way less efficient than wired. It's not supposed to be as fast as the cord, just fast compared to other wireless chargers.
No: Voltage, Amperage, Wattage
Yes: Electrical tension (silly English speaking people), Current, Power
Bjorn Roesbeke Current and amperage are the same thing, wattage is voltage*amperage, and power is not a unit of measurement.
Sure, i know what people meant to say but there are no such terms as something-age.
You're mixing up things. (NL: grootheden en eenheden)
Bjorn Roesbeke Voltage, amperage, and wattage are all in the Merriam-Webster dictionary.
@Marcus Coster
They were added to the dictionary due to years of missuge
But things like meterage and kiloage aren't accepted terms when discribing length and weight.
So why should the terms be accepted when it comes to electronics.
Vinxian1 Things are added to a dictionary when they are recognized as words. I'd say over a century of use is long enough to become a word. I don't live in a metric country but mileage is a word used often here, and poundage is also a word.
With higher power comes higher responsibility.

1:30 You made me watch the Spiderman movie once again. 😂
The charger for my Motorola Moto Z Force is pretty expensive coming in at around $40 (30 after VZW subscriber discount). That's due in part to the 30W/ 5.7A it can supply to the phone but finding a portable charger that can handle something similar is nonexistent. Thankfully I have the Turbo Charge Moto Mod which works beautifully.
Boonk gang whole lotta gang shi na'm sayin

We do have FastCharging.
How would you know? Have you seen the source code and/or the schematic for the circuit board that shows how the charging system works.
Finally! Luke! First time in the last month....
My suggestion to everyone looking to keep their phone's battery healthy is to use quickcharge only when you absolutely need it. If you are charging over night just use an old charger (like a 500mA one) to charge your phone. The battery will stay cool and won't degrade over time, and by morning you will have a fully charged phone. Ideally you need to keep your battery between 20%-80%, but most important is to never let your battery empty completely
good spot, thank you! corrected it
Charge iPhone with iPad charger. Done.
The "charger" is in fact not even a charger per say, it is simply a USB power supply, the actual real battery charger is on the PCB inside the phone, ipad or laptop etc, However there are handshakes between the device and power supply in newer USB specifications that goes along the lines of "hey phone, USB power supply here - I'm only capable of delivering 1Amps @ 5 volts, so please don't go over over this as I might have to shutdown or I will become unstable and hot - the charger said" - so the phone listens to this basic coms designed into the USB power supply and limits its charge rate (current) into the Li-Ion / LiPo cell so as to not draw too much from the external supply. Have a read of this that lays out how the specification evolved from the first USB ports: www.maximintegrated.com/en/app-notes/index.mvp/id/4803
When the RUclips video matches your keyword search word for word
everything we learned in the old days of taking care of batteries is obsolete now.. its actually better for modern batteries to have many small charges instead of completely draining and charging them
Thnx to qualcomm not 🍏💩

Ask karim
Haha fast charging... Did someone say Apple?
No. No one did. Someone said Samsung tho

PissedOffHoneyBadger one day
My laptop has a fast charge USB slot and it works on my iPhone
My phone uses bursts to quick charge. The phone will monitor temperature, the power delivery, communicate with the charger and for ten minutes crank up to 30W charge mode. Once the phone gets too warm or the power being pulled from was wall stutters, my phone tells the charger to hold back.
I can go from 5% to 32% in 20 minutes. If My phone stays at a constant safe temperature, burst charge stays on for 15 minutes making the 5% to 32% charge take 14 minutes. In some situations where the temperature in the room is cooler, my phone burst charges to 60% in 25 minutes.
Only downfall is that I need an expensive type c cable and 30w charger for my phone to quick charge. The plug alone is £36.99. The cable is £18.99.
i want a charger where my phone can go super saiyan 3 real quick
Omg stop using waltage, amperage it's just dump! They are called power and current! Not even hard to understand.

Haha tries to sound smart, looks like a dickhead.
