Can i charge my s8 with my laptop charger which also has a USB type C pin?
It is charging and it's faster. Phone gets slightly hot.
Should I do it? Or will it harm my battery?

I wouldn't see why not Your device has its own loads of safety Fail safes that would disable charging if something was afoul
Yo man. You are able to charge it using your laptop or whatever type C you have. I did sometimes using Macbook Pro type C charger. As others said. I believed the device fail safe is there.

What is the output voltage on the laptop charger? It should have it printed on the charger unit somewhere. This is very important.

I Apparently read incorrectly, I thought you meant charging off your laptop not the laptops charger itself.... Normally laptop chargers are 15 to 19 volts which is way to much but again I am pretty sure the devices fail safes would kick in and limit charging....
You could, it should still limit the charging rate to 15W.

Nope, it depends what the voltage is. Your statement is correct if the voltage is either 5V or 9.6V, as those are the voltages used by the phone.
But laptops are usually way more than that. And if OPs one is higher voltage, it's going to kill the battery and potentially cause cause it to swell up and expand.

But really, do you guys notice that it takes a long time for the battery to charge?
I think when available, I'll buy a bunch of batteries just to have handy.
well the battery is 1500mAh the nexus charged pretty quickly but it was 1400mAh i am not sure how much difference 100mAh will make on charging the battery but that could be a possibility.
Charging with the computer will always be slower, if that's what you're using.
I wonder if its the charger. The provided charger has an output rating of 0.7A. I know some microusb chargers I have seen are rated as high as 1.0A. That could be the difference.

Interesting...that could be. However, maybe it's 0.7A for a reason? Perhaps the battery needs to have it at that "flow rate." ???
We did get a different charger over the i9000, they had a separate USB cable and microUSB wall charger. We obviously don't have that setup.
Some phones have Li-Pol batteries and they have to charge differently. This could be why it's taking so long to recharge.
check a tmobile store or website for the new portable micro usb charger. charges your phone on the go and recharges itself via a usb charger the vibrant ships with or your computer. i got mine and was a lifesaver the other night when i needed to leave my house with 10% charged.
I hate saying this, but: I literally LOL'd from the title of this thread.
I completely agree. Charging takes fuggin' forever. My guess would be that turning the device off helps speed this up, tremendously. But of course, who wants to do that?
That said, battery life has been impressively long, provided you turn off Samsung's widgets. :/

That would be a huge design oversight if a generic charger caused problems with the battery. I'm sure Samsung thought about the user charging with a generic charger.

How fast is fast, iceshinobi?
I have conditioned my battery twice and going from empty with the phone off and pluged into the wall not via usb-pc, took me over 4hrs each time.
If the charger is 0.7 going to a 1.0 would be a huge improvement. The only worry would be the extra heat and problems that might cause. With NiMH batteries quick charging is preferable to slow charging, is this the same for Li-ion?
came here for insight as well, woke up at like 5am, phone was almost dead, 10% battery or so
turned it off, plugged it in to the wall charger and it is now 8am and it is maybe 60-70% charged
what the hell?
with my g1 turned off i can go from 0 to 100% charge in like an hour or so using a USB port. now i know the battery is smaller but c'mon... this is ridiculous.
Could it be that the phone just has to break in? When I first got G1 it would take about 4 hours to charge I remember, now a year and a half later I can get it to 80-90 percent in 1 and a half.
The computer USB standard is 100 to 500 milliamp, the USB walloulet adapter (charger) Is 700 milliamp, our batteries are 1500 milliamp and that's why.
USB cables have a certain standards witch includes voltage and current standards.
If you want a fast charger look for a hard wired 1000-1200 milliamp charger with a micro USB connector on ebay.

Do you think it would be safe to charge the evo with a 2.1 amp car charger? I found one on ebay that says its made for the iPad but I would love a faster charge on my epic.
In general, the slower you charge the battery, the longer it will last. The effect is pretty significant.
I don't know if that much current is safe.

It's more complicated than that. Just because the charger is able to provide 2.1A doesn't mean the phone will actually draw that much current.
The charge control circuitry is built into the phone. You are just providing a +5V rail as the charging power source via a standard USB connection. There is no charge control inherent in USB itself.

It will only pull as much as it needs. I use higher amp output chargers and it's not a problem. It will charge faster, regardless of what you use, if you turn the phone off.

It could be due to the usb micro charging standards... Many chargers do not adhere to the standard, and this may cause some of the newer phones (droid X, galaxy S phones) not to charge at full power. Most older phones simply did not care, and would use all the amperage they could get their hands on.
Basically, if the D+ and D- pins of the USB cable are not shorted, then the device will draw minimal power from the +5v rail. It is probably drawing <500 mah, and could even be drawing as little as 100 mah from the charger.
Getting a proper 1A charger could fix this, but I'd like to test it out myself when I get the chance..
http://www.griffintechnology.com/products/powerduo-for-ipad
These work good. I use the ac one. Only thing is, like some have stated, even when charging when phone is on and using the phone, the battery will still go down. Maybe 2.2 will fix this or a patch.
I'm not going to debate fast vs slow charging. This isn't like debating what is the best charger for AA rechargeable nimh, fast or slow or charging method.

Atrix on and sleep/idle wont charge as fast as of because of things running CPU load.
Atrix with no wifi, and bt on, and normal sync. Its taking mv's per second vs off where its able to gain the same charge rate while off. ( bare minimum resources used)
if you want to know what is better for your phone, I think it's the same.
As Ciloteille said, if your phone is on, it will take more time to load, that all for me
It's better for battery to charge slowly using USB from PC. Also, for battery is better to reduce heat. For example if you charge and play games, processor and batter will produce more heat.

Basically for every battery is better to charge slowly because chemical process is less aggressive and in the same time produce less heat. PC USB can not provide enough current as charger.
I recommend to read this article How to Prolong Lithium-based Batteries .
PC USB is 5volt correct? Were as most wall charger or car charger is 12 volt?

PC USB is 5V but charger is also about 5V. Difference is that PC USB 2.0 can provide 500mA and chargers more. For example Motorola charger provide 5,1V and 850mA. That's way charger charge battery faster. Some charger could provide 1000mA or more.

Ya that what i was just looking at. Basically what i am gathering from your info and that article is most chargers are designed to fill the battery fast, but what you reall want to do is a slow almost trickel charge like with a car battery were a low steady voltage and amperage is applied
Chargers are designed for fast charging just because users wish to charge battery faster is possible. They don't care about battery. Anyway modern battery will last longer than ordinary possession of the phone.

It means that charging faster will reduce the overall life of your battery because the battery and phone doesn't support it. The Galaxy S5 supports USB 3.0 and Qualcomm Fast Charge.
Also, the fast charge on your Ace 2 just means that it will draw maximum power from USB ports. It doesn't change charge speed with a wall adapter.

Use the original cable and adapter. If you think that's too slow to charge, like taking up to 5 hours, that's unusual. Let your carrier or the store check it for you.

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.
