I was watching this video (https://youtu.be/D0ShDrNGaP8) at the 4:42 mark he said if you want to charge faster than the 18w charging get a quick charge 4.0 charger
Has anyone tested this yet? Will a quick charge 4.0 charger charge faster than the 18w charger included with the phone? If so how much faster

There's a reason that Asus went with 18W charging and 5000mAh instead of faster fast charging and a smaller battery. The 5000mAh battery isn't designed to charge faster (doesn't have a thick enough separator between anode and cathode). If you charge faster than 18W, it will heat up too much and the battery will both degrade and swell faster. I wouldn't recommend it.

Even with the ai charging built in? Isn't it suppose to limit the charge to the battery preserving the life of the battery

But how can they say they support quick charge 4.0 with a 18w charger when that was the same 18w they used with the 5z which was quick charge 3.0? I'm confused about that
Sent from my ASUS_Z01RD using Tapatalk
Quick charge 4.0 is a charging standard and meeting it doesn't mean how fast it will charge but which charger will allow fast charging. Asus most probably set limit to 18W and the phone won't draw anything more than that.

Hello, I have a question regarding charging. In fact, when I use the OEM charger which provides 830mA of current to charge my Atrix 4G, it charges fast (~+50%/h). However, when I charge it with the charger of my Note 2 which supplies 2A of current, it charges very slow (~+12%/h). So, I find this very weird since theoretically it should charge even faster than with the OEM charger that came with it since it supplies a greater current. However, when I charge the Note 2 with the Note 2 charger, it charges with a reasonable speed (~+50%/h). Any explanation?:banghead:

well the note 2 has a 3,100 mAh Battery and needs a specific charger for it becuase its a big battery, on the Artix 4g its a 1,930 mAh Battery, if you look on both of your chargers (the wall mount)it can show how much Volts,Hz,mAH it will charge.
The charging current of a battery is limited by its physical capabilities. You cannot charge a battery designed to be charged at ~800mA with 2A of current - your battery would die very quickly and possibly even catch fire. Each phone has a circuit that limits the charging current to a value that is known to be safe for batteries used with that phone. This means that plugging a bigger charger to a small phone won't make it use the full capabilities of it.
Besides - in case of Li-Ion batteries, the faster you charge the faster your battery will degrade in time. This is the reason why I charge my battery using a USB connection to my PC, where the charging current is limited to 500mA (USB 2.0 limit).

fast charge is generally a feature that needs to be built into a custom kernel
Don't know about you but my S5 chargers incredibly fast compared to my SIII and Nexus 7. Even with fast charge on.
Agree, my S5 charges at 1.2A given a charger capable of this, and that is fast.

Yes, the S5 charges at 2amp. (Kernel reports 1800mah)
If your phone is reporting that it charges any slower than that, it's an energy deficiency of the charger supply, bad cable, or bad micro usb connection.
I use an app which reports charging current. With a standard micro usb cable i never morw than 1200 mA (and about 450 mA from a PC/mac usb plug)
Sent from my SM-G900F using Tapatalk
While it's true that the phone ships with a 2A charger, the charging current does not exceed 1.2A AFAIK.
Gotta love MicroUSB 3.0.
It already charges from under 10% to 100% in a mere 2 something hours (bundled charger and USB 3 cable). You want something much faster than that???

Yes I think in the end it is something around this current. What the apps report is more "charging in 1800mA mode" and not really charging with continous/real 1800mA. If you like to know more exactly what the current is you may write down time/percentage values for e.g. every 5% of battery power starting with an nearly empty battery. Then you can draw an line of the effective loading current.
With the original charger you should be able to get stable 1800mA but if the loading circuit of the S5 really goes this high I did not check.
I believe it peaks at 1800mah with the screen off. It is 1200 mah limited when screen is on.
Sorry to awaken this post.
As most of you, my S5 reported charging at stable 1200 mA with wall charger, probably 1800mA when turned off.
But, I can say a custom rom unleash battery charging in the same conditions as stock rom. I get stable 1800 mA with LineageOS, even screen on, with original charger and usb 2 or usb 3 cable.
Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
Anyome using a 2A charger instead of a turbo charger?
Like a samsung 2A charger
Or a 2A power bank?
Any issues?
Because 1150 mah is too slow
I was also wondering this.I tried it with my 2,4a ipad charger once and it was charging twice as fast, but i dont know if this is good for the phone. Using the normal charger again to be sure.
With normal 1.2A charger, it takes almost 3+ hours for my phone to fully charge. I used my Galaxy Note 10 charger which is 2A and it got charged in 2 hours. I read it in the forums that even with 2A charger, we cant take the advantage of turbo charging as it will need a charger of 2.4A.
I dont know how 0.4A will make a difference but still, my knowledge is limited in this case and wouldnt want to comment on it.
The charger has to be Qualcomm QC 2.0 certified (that's a specification) to take advantage of the turbo charge mode. The amps put out by the charger is kind of secondary in this situation as the charger and phone both need to be "talking on the same page" i.e. QC 2.0
At that point (charger is QC 2.0) the special circuitry kicks in and goes into turbo mode. So its a little more involved than just throwing more amps at the phone. If you google Qualcomm QC 2.0 specification then it will give you a better idea of what it is all about.

Turbo charging steps up to 9v and 12v depending on what wattage the phone can handle.
I think our phones are 15w and the Style is 20w or so.
I can't get my phone to charge faster with a 2amp charger though, only my turbo charger.
I used digitech 2.4amp charge ans works like a charm superb....
It isn't causing any issues? Like battery degradation?
Sent from my XT1562 using Tapatalk
I've been using my Moto turbo charger every night for a couple weeks now and haven't noticed any issues. The phone doesn't seem to let the battery get over 35'C when its charging, so I don't imagine it'll damage the battery.
Think I may get a car charger soon, sometimes I forget to charge at night so it'd be cool to get a full charge on the drive in.
Battery will very likely not last as long when doing fast charging always compared to "normal" charges
Any fact to back that claim?
Im using a Belkin 2.1A charger, no problems whatsoever.
So what's conclusion is it safe to use 2a charger without doing damage to battery

I'm using a 3a charger and it's fine
You can't harm a battery with a higher amperage output charger. The phone will only consume what it is able to. If the voltage was higher (excluding quick charge adapters) then yes that will do damage, but that's a strange situation as no charger should do that unless it's quick charge.
That being said, on hand I do have a feeling that quick charge can actually do long term damage if used a lot but on the other hand, it seems to limit the maximum temperature to around 38'C. Above 40'C can cause irreversible damage to the cell. I'm using a car charger now and when the phone is in use, it gets up to around 38 or 39 and it cuts back on the charging current.
Interesting article explaining Qualcomm, fast charge, turbo charge using all the same technique under different names. They all use the same Qualcomm technique.

I have 4 chargers on hand listed below...
1. Original Samsung Adaptive USB Charger
2. Anker PowerCore+ 10050+ QC 2.0 Charger
3. Anker PowerCore 10000
4. Pleson Fast Wireless Charger
Now my question is why is my S8+ charging similarly with all these chargers? Example @ 30%.... The Adaptive charger says 1 hr 9 min (reads fast charge), the Anker 10050+ says 1 hr 25 min (doesn't read fast charge), The Anker PowerCore 10000 says 1 hr 25 min (Not a fast charger), and the Pleson Fast Wireless Charger says 1 hr 44 min.

Because only 1st one is actually fast charging your phone.
You should try 2 and 4 with original cable. If you have qualcomm version of s8 shold work
I'd echo the original cable and the wall plug that came with the device. Retry all 4 of these with the original cable and the wall plug.
Well I don't know if the Anker products are charging oddly because one is QC 2.0 and the other isn't, yet both have same 59 min charge time. So I question is the Samsung Adaptive charger is charging slow or fast? Here are some pics of the remaining charge with original black USB Cable.
From my experience, Samsung Devices don't really play nice with qc certified devices thanks to Sammy doing their own thing. What you are seeing is what made me buy Samsung's power kit.

Estimated time. Don't expect them to always show exactly the time.

Compared to my s7edge this s8+ charges a lot slower. The s7e would fast charge and wirelessly fast charge from any third party wireless pads/adapters.
The s8+ is finicky about what activates fast charge (especially wireless) and even while in fast charge it does not charge as fast as s7.
My guess is samsung slowed the charging down to help with battery degradation.
I found a weird thing last night when I set my phone to charge at 2 AM with about 7% battery just to wake up around 6 AM and it being at 86% charged. That was a long time, I don't know what's going on. Either the phone isn't quick wireless charging or the Pleson Fast Wireless pad I have sucks.

So, I've seen this behavior too. If you see the charge stuck, unplug the cable and plug it back in. I'm not sure why, but that fixes the issue immediately.
Are you guys charging in a warm room? S8 will stop charging if the battery exceeds a certain temperature. Samsung really went overboard with battery safety after the Note 7.
