So, from my understanding, the OEM Samsung fast charger for the Galaxy S6 is 5 volts 2 amps. I recently bought an Anker Elite Dual Port wall adapter, which is capable of 5 volts, and up to 2.4 amps if pulled per port.
When I plug in my phone to a standard OEM adapter, it says it is fast charging, and something a long the lines of 1 hour and 30 minutes until fully charged, but when I plug it into my Anker adapter, it says the same amount of time, but a standard charge. Ie not displaying as fast charging, but with fast charging times. With monitoring apps, both pull 1 amps.
Does anyone know what could cause this? Both pull the same but one doesn't say fast charging.

My Samsung Droid Charge charger has an OUTPUT of the same voltage and 700 MILI amps.
My Blackberry Bold charger OUTPUT has the same voltage but is 1 AMP output... or 1,000 MILI amps.
If I use the Blackberry charger in my new Samsung Droid Charge will that mess anything up in the Samsung? could it shorten the life of the battery?
Thanks!
sure can, including wall chargers and car chargers
well if the amperage doesn't match exactly couldn't that mess up the Droid Charge?
it should be fine...but you might confuse your phone into thinking that it is a cutting edge smartphone circa 2006
If the power output of the charger you want to use is rated at less than what the OEM one is, you would only damage the charger itself if it isn't made properly.
The phone will pull a specific charge from the charger, say 500mA as an example. If the charger is rated at 400mA and doesn't have wiring to prevent an over-draw, you will damage the charger, especially if you use it for extended periods of time. If the charger does have circuitry to prevent over-drawing power, you'll just charge the phone slower. If you use a charger rated at 1000mA and the phone pulls down 500mA, using a higher rated charger doesn't make the phone charge faster as it will still just pull the 500mA. You'd just be less likely to damage the charger using one rated for more than what the device will accept.

I had purchased a usb cable a couple of years ago on kijiji for my BB bold back then because I didnt have a charger for it. Then I got the S3 and one time I randomly used the BB cable connected to the S3 charger via USB, I noticed the phone charged WAYY faster than the normal S3 cable does. Now I got an S4, and it still charges a lot faster than the normal cable for it. In fact I'm charging both my S3 and S4 at the same time right now, the S3 with normal cable charged from 4% to 15% in the exact same amount of time my S4 charged from 48% to 72% with BB cable. Does this mean I'm damaging my charger that's connected to the BB cable?

If by charger you mean that little box that plugs into the wall, that is actually a power supply. It just converts 120VAC 20A to 5VDC and whatever current it specifies. Also the stock s4 uses qualcomm quick charge, which means that if you use the stock power supply with the s4, it will charge at up to twice normal speed, provided you have a compatible cable (which it seems the BB cable is).

I've noticed that charging with 500mah charger, charges the battery MUCH slower than a 1000mah (1amp) charger, which charges really fast. I'll need to time it, but I'm thinking the 1000mah charger charges the stock battery in less than 2 hours, where as the 500mah charger takes many hours, I usually let it charge overnight.
My question is, is there any performance gain to slow charging vs fast charging? ie: slow charging giving a deeper charge, vs fast charging?
any opinions?
i use a 2amp charger i had already that fully charges the O3D in around half an hour/45 mins. get the same runtime whether i use that or the stock charger.

Any chance of a link to this charger, I'd really like that sort of charging speed.

My guess would be anything that would charge an iPad... those require like 2.1amp, so that would be a 2amp usb charger.... I've seen 2.1amp home chargers, car chargers, etc... all because of the ipad I'm guessing.
Its not that simple. Any device that uses USB for charging can only pull 500ma, that's a universal agreement. To get around this each manufacturer uses a method of "informing" their device that it is connected to a charger that can supply more current (HTC shorts the data leads in the supplied charger I don't know what LG does). I have a 1amp car charger but it still only gives 500ma but the genuine LG charger gives an amp because the phone "knows" it can supply more.
I'm going to stick a test meter into my LG chargers over the holidays to see how the data leads are connected.

The charger i have is a noname brand. I bought it from walmart for 6 quid. It also came with a 2amp car charger and a micro usb cable.
Micro usb cables are not standardised like that. Ive never heard of such a thing at all. As far as i know most phones will "fast charge" if they dont detect a data connection and dump as much current as they can into the battery so you can pretty much present them with whatever current you like and the charge time will just get faster. There is probably a hardware limit to that somewhere in the charge circuit but i dont know what the limit is. 2amps is the highest power usb charger ive seen but its not exactly aomething i regularly keep an eye out for.

Slow charging is always better as this will allow the optimal number of battery cycles before the battery's capacity will start to degrade.
So if you only ever slow charge then your battery will have a longer life cycle.
On the Samsung Galaxy Note 2 (basically all Samsung Galaxy device), their two data pins on the official charger are shorted to be verified as a official charger and enable fast charge. If I connect it to a no-branded usb 12v charger, it takes a very very very long time to finish charging (like 5 or more hours bevause it only want to recieve 350mA rather than the higher rate on the official charger). I remember I dont have any problem charging my HTC Desire HD with the Samsung charger. But if I use HTC charger on Note 2 it also needs hours and hours to charge.
My question is what brand/model uses the 2 data pins to verify (or know how to charge when they are shorted) so that damage will not occur. Anyone knows the answer?
Several things going on here. There is a difference between USB and AC charging mode. I have had to short two wires in my car adapter to get my Nexus 7 to start charging with AC mode. Don't assume that every charger is capable of charging at the same rate. If you have a 350 mA charger, it won't charge your device as fast as a 2A charger.

I didnt mean that every charger can charge at the same rate. I wanna modify a 2A charger but I'm scared that if I unexpectedly connect it to an incompatible phone and something bad will happen. If a no-branded charger (data pins are not shorted) is connected even it's on the wall plug, the device will set it as USB charging and lower the receiving voltage so the device will charge very slow or the battery percentage will be dropping even when charging while using. My HTC charger can charge the phone that it belongs (Desire HD) in 2+ hours but the Note 2 needs 5 hours (this means that the HTC charger has no shorted data pins). And the Desire HD wont get an error when using a charger with shorted data pins (Samsung charger). What I want to know is what phone cannot be used with a charger with shorted data pins in case someone (or myself) use my modified charger to charge a incompatible phone and let damage occur.
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. I am confused.

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.

I have no issues with my chargers, use stock charger blk, use sammy wireless charge pad with aftermarket cable and s7e wall plug charger and no issues. Still get fast charge. I even have a portable 10000mah sammy pack and use my gopro usb-c cable n gef fast charge.
Do you mean this one....

Had similar problem. All my Anker QC2.0 doesn't fast charge my S8 while 3.0 does. got them both refunded while they are investigating.

Strange
does that mean S8 has QC 3.0
Yes I am in talks with Anker as well, seeing what they find out about my QC 2.0 Anker charger.

They sent me another QC 2.0 car charger, and it did not fast charge. I am going to try Berkin USB-PD car charger and see how it goes.
Estimated time. Don't expect them to always show exactly the time.
I have QC 2.0 and 3.0 chargers and they all "fast charge" but I don't expect what the estimated time show to fully charge be accurate or else they wouldn't say estimate.

Yes except bestbuy carries that with a dual Samsung fast charger for car and a nice wireless upright fast charger all in one box for about $99 on sale every other week. Way more consistent everywhere now.

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.
Should have my phone arrive Wednesday from Amazon. Being in the UK I needed to sort a 3 pin plug and so have purchased an Anker 18w fast charger.
Anker Fast Charger, USB Charger 18W USB Wall Charger PowerPort+ 1 for Galaxy S8/S7/S6/Edge/Plus, Note 4/5, LG G4, Sony Xperia XZ, Nexus 6, iPhone and More[Black] https://www.amazon.co.uk/dp/B017VXARME/ref=cm_sw_r_cp_apa_.dDvBbXP47Z9E
I have since notices however that the braided cable supplied with the phone is type c to type c.
Do I need to use the supplied cable to get fast charging (I'm which case Anker charger no good) or can I just get any other cable to use with my new charger?
You will not get the 27 Watts the phone is capable of using. You will get 10, 12, or 15 Watts, I'm not sure which. This will get you charged in about 2 hours.
If you want the fastest charge (with caveats listed below) you need a USB PD (power delivery) charger which can only use type C both sides.
Note that the Essential phone doesn't charge at full power the whole time. I usually get about 50% charge in less than half an hour, then it slows as the charge level increases. Zero to 100 in a little under 2 hours. This is great if you need a top up to get thru the day.
