A 2 Amp charger mean its capable of giving max 2A to a load, the phone only needs 1A so will only use 1A even on a 2A charger
if not what kind or which brand of charger you recommend ?

Original charger, always

But i have charged my phone with a samsung 2A charger a few times , and the charge speed was near twice , so the phone does not use just 1A

Hey, which one is it? I would like to know =)
Model name or sth, should be written on the charger =)

It was for my friend`s Galaxy Note 3 , he does not have the phone any more but I will find the charger and pm you for the model

The phone can handle it but the 1a is the suggested and anything more can damage the hardware. I have a rapid charger that will charge my battery to full in about 30 min from 0. It works on the stock kernel so it is not a custom kernel option. And the fast charge is a pc USB setting if you read the discripition.

Really? I've always heard that the phone knows only to pull 1A from the available amperage. I've always heard that using something less than 1a can damage the cord and possibly the charger itself.
Also: Using fast charge can seriously degrade your battery over time. Better to only use it when in a pinch.

That's why I said it can damage the device. Mine is a stand alone charger so no damage to the cord.
I only use it when I really need to. Like when I have kill the battery as well as the Mophie pack and am in the middle of nowhere and need to make a fast call.

I see what you are saying. I read it differently earlier for some reason. Actually: I know the reason. I've been severely sleep deprived the past several months and have been experiencing sleep paralysis the last several months two or three times per week. Thank God I'm getting a sleep study done soon! My level of alertness is way down from what it used to be... Sorry to get off topic with that stuff, but I felt the need to explain.

Will this only damage the battery or more than that ?

Yeah it's not good for battery life. If you want to get the most out of the battery I wouldn't do it

While I would tend to think HTC would be smarter then to skimp on the hardware. I will error on then side of caution and say no. You "could" mess up the port and the board.

My Htc one M7 is charging in about 3-4 hours, from 0% to 100% with original charger and cable, it's ok?

Wrong So Wrong
Fact with stock kernel htc one m7 charges nearly 20 mins quicker
there are pro's and cons to this unless used at the right time in the right situation
sick of people saying it will harm it or that it is there to use only 1a
first of all the stock charger allows 500ma of charging and 500ma for the phones consumption whilst charging
when turned off it should only charge at 700ma
a flaw that was left on purpose by htc for monetary gain
holding fast charge and even full charge capabilities back widens the gap between the m7 and the m8
making people want to buy the m8 charger or better the m8
here's why and how they hold it back on it's full speed charging with !!!!!!!the stock HTC charger
Here is the explanation
The best way I have ever heard it put is like this
Where current is water
Imagine a water barrel that is being filled up at a rate of 1 liter an hour
The barrel has a over flow pipe aka battery if this pipe is only wide enough for half a liter an hour and you turn the tap filling the barrel to 10 liter an hour how much is the over flow receiving still half a liter.
So here is the big if and but
If you are using a 2.1a 5.1v ipad charger
Whilst gaming you have the CPU GPU and battery making heat and thus degrading Battery life and performance
If you turn the m7 off or have all apps closed and phone idle then this is far better than gaming with the stock m7 charger
as heat is the NO1. killer for battery depletion
As for comments about voltage of other chargers are irrelevant as the circuit in the phone limits voltage with a simple I/0 circuit if voltage is either under or over pre set parameters it will do nothing as it won't allow any flow of current at all
Unless lots bigger (BANG)
How is the current limited
Self explanatory as the charger states what it is built to supply
Conclusion is simple amps are limited by the charger plug or USB port
Voltage is not limited but safe gaurded by the phone so if your phone registers a charge with a 5.3v plug then it is fine as long as you use it sensibly
Apps are highly unreliable as they are a close prediction at best
And don't correctly include what is used by the phone
Also some current will be being stored all the time in capacitors
Fact the m7 charges quicker with higher ampage application measuring ampage will not be accurate.
The only accurate way is to time it from empty turned off
And blind people who say HTC know best do not understand the workings of any multinational corporation
By holding the fast charge back widens the gap between the m7 and m8 meaning more people will go and buy the m8 fast charger or even better the m8

Fast charge & USB

Hi everyone, I'm looking for more info about the fast charge function of the Note 4: I can read on the charger that it either provides 5 on 9V. Does this mean that I can supply 9V on the USB port to fast charge my note 4 ? Does anyone know how the charger detects wheher it it should supply 5 or 9V?

Yes, it means that that charger will deliver power at 9 V (at 1.67 A) to the phone.
As for how it decides which voltage/current to use, it'll be as a function of the battery's charge level, temperature, and probably some other factors, but that's getting into some very specific settings for the phone/charger system by that point.

thanks for the quick reply! I've got a couple of Dc Converters (buck) and lipo batteries (11.1V) and was wondering how the phone signals the charger it can accept 9V and if I can use my DC step down to feed the phone with9V...
I guess I will have to try

I guess it requires original charger for that function, probably with kernel modification you can disable that only 9v OEM charger use for QC

Hello guys ! Do you think this fast charging function is alright for the battery ? as far as i know high current may damage the battery .

I agree that it might be damaging to the battery (but obviously not extremely damaging). Why else would there be the option to switch off fast charging? I've switched mine off anyway because I have no use for it as my phone charges overnight and makes no difference how quickly it gets to 100%.

I personally thought the option to disable Fast Charging was Samsungs' way of reminding us, or letting the uninformed know, that it can do it.

The generally accepted rule amongst radio control hobbyists is that provided the battery is well made, it's not the current that'll kill a battery - it's overcharging it (over 4.2V per cell on a LiPo). Provided that the charging circuit is good (and I have no doubt it is of a high quality) we shouldn't see any degradation in battery life when used with the fast charge process.
Others may chime in with more info, but that's how I understand it.

l believe the fast charge is safe for the battery as it charges it at 1C (=1hr charge) which is actually not so fast.
Here is my tip: I have an old charger to charge overnight and use the mote 4 charger only for fast charging during the day (I leave it in my bag). I'm actually lookingfor a way to make a fast charging battery bank.
So here is my question again: has anyone tried supplying 9V to the phone ?

best device in charging
its charging up the whole battery in about an hour, i really like that and the battery gives me a full day

So far right now i can talk for about an hour and play games for about an hour and leave it on overnight and all day and still have 82% left. I'm super impressed!

YOAH!!! Thats insane!

I know that the amperage on the charger is huge in its speed.
I used many custom Roms and kernels in the past on other phones with fast charge. I used several chargers and always charged much quicker with higher amperage outputs. Some were as low as 300 MA to as high as 1.2A. This is why the amperage is so high on this phones charger. The voltage is needed to push the charge quicker. Good luck finding high A charger at 9v.
My 1.2A charger i use as backup is much faster then the 500/700ma ones I have but they are all 5v and can't compete with fast charge.
Sent from my *ROOTED* Note 4 SM-N910W8

I'm also looking for a power bank that would be able to charge at
- 5V 2A,
- 5.5V (Galaxy Tab S)
- 9V (Note 4).
- with 2x18650
- able to charge itself fast too;
- charge-through (charging a device while changing itself).
i now have this ENB model, but it does not deliver 2A to Tab S (and charges at 5V not 5.5).
And it charges itself with 1A even from 2A-capable power supply.

Hi all,
I notice something that the note 4 does not charge fast after I installed S-View cover (original one), although an indication appeared that it is using the fast charging function.
I guessed it assume that the cover is open and charge slower. However, if I removed the S-View it charge noticeably faster.
Do you think this a bug in firmware ??
Thank you,

The so-called USB fast chargers query the device to be charged. Devices capable of fast charging at 9V DC have additional circuitry in their USB ports that the charger can detect. If the charger doesn't detect the circuitry, it falls back to 5V DC mode, like any other USB charger. Assuming the fast charger is functioning correctly, it should not over-charge an older phone or tablet that doesn't support fast charging; it will simply take as long as the original "dumb" USB charger did.

Does Adaptive Fast Charging Come Pre-Enabled on the Note 4?

Was wondering, Does Adaptive Fast Charging Come Pre-Enabled on the Note 4? Or do we have to go to the Battery Settings first to enable it?

When I got mine, it was enabled already.

Oh, if your fast charge your battery once, does it reduce your battery's lifespan in the long run, or does it need to be fast recharged several times for a notable difference?

As a general rule, the faster you charge the battery, the hotter it gets. The hotter it gets, the more quickly it will degrade. I still use my S3 charger to charge the Note 4 overnight.
Does it really make a noticeable difference? From what I've read, probably not. But I don't think there's been much objective testing. Just using fast charging once is highly unlikely to affect it in noticeable ways at all.

If you've charged the battery once using the fast-charging method, is that going to impact the lifespan of the battery? Or does it take multiple fast-charges for the battery to begin to loose its charge?
Nowadays I use the regular 2amp Samsung charger that came with my Wireless Charger.

I edited that in right after I posted, but I guess you beat me to it. As far as I can tell, it's a gradual process. Unless the phone seriously overheated during the one charge, it shouldn't have much effect at all.

Thanks, looks like I don't another one of the Fast Adaptive Chargers after all, haha.

Honestly I'm not sure if it diminishes battery.
I have to take it off because I'm using a Zerolemon battery and it doesn't charge all the way up unless the fast charging is off.

The adaptive charging is built in as long as you're using the included charger. It charges at a higher voltage so it's not as damaging as say, a 3 amp charger would be, but it takes many many fast charges to affect the battery's performance. Generally speaking though, the faster you charge the more capacity you lose over time, but the worst thing you can do is charge it &leave it plugged in for hours fully charged. I use an old Bluetooth charger that's 500mah when i charge overnight & the fast charger at work or in the living room.

It is safe to charge all the time my Op3T with dash charge?

Hello. I want to know if it is safe to charge every time my Oneplus 3T with dash charge because it is a very fast method of charging (too much maybe...). I am asking here because i haven't found any other question like this. Thanks for the help and sorry for bad english.

Yes, because it doesn't charge with 4 amperes all the time. As the battery juice increases, the current decreases to prevent battery damage, so you are fine.
Plus, every manufacturer recommends using original chargers.

Question Can you use a different charger brick/block?

Im planning to use a 18W charger to lessen the heat from the phone and to increase the life of the battery from using the 33W brick. Is it okay to use a different charger brick?

yes, I got this phone less than a week ago and charged it two or three times, and didn't use original charger yet, so no worries, it'll work ok

Same here. I also use other charger and did not use 33 w charger yet. It charges fine without issues but a bit slower. It is up to you to decide to use 33 w or lesser w charger.

It won't effect anything except if you want fast charging.
If you can software disable fast charging it doesn't matter which brick you use.

Too bad. Not familiar with that brand at all.
Usually it's getting fast charging to work rather than the inverse.
I think I would rather have your dilemma.

My phone doesn't charge with 33W even with original charger,
So many users also complaining the same that it isn't charging fast enough
I use "battery charge limit" magisk module to limit charge limit
Or
You can use accubattery app to set alarm at specific battery charge limit

I use zmi charger 18w with pixel rom. Still recognized as fast charging!

Make sure the battery temp is at least 82°F before you start charging. I get best results with a start temperature of 85-95 F.
Keep the temperature under 100F while charging. Use cooling if needed. Fast charging will warm up the phone fast especially in high ambient temperatures... if will need cooling. A fan and/or damp microfiber cloth helps. Keep it of direct sunlight
Keep the screen off when charging as it will completely skew the charge curve.
A quick 2 second look doesn't seem to hurt though. Likewise I use bt and Poweramp to listen to music while charging with no perceivable impact on my Note 10+.
Play with it and see how it behaves...

Would a 10w charger also work?
