Hi,
Selecting a charger for mobile devices seems to be confusing nowadays, atleast for me[emoji16].
Can help me how much power does the S7 edge needed for Fast Charging and non Fast charging? I understand that the original charger included in the box has 5V 2A or 9V 1.6A output. Am I right to say that when fast charging is off, it will use the 5V 2A and if it is on it will use the 9V 1.6A?
Reason for asking is, I am using the original charger at home and my old htc charger from M9+ in the office. But when I use the htc charger with 5V 1.5A output, charging suddenly stops at 50-60%. I observed that the htc charger gets hot than its normal but my phone doesn't get hot. I turned off fast charging when doing this. It seems that the htc charger cannot handle the s7 edge and stops at certain point when it gets hot.
Now, i'm checking which wall charger should i buy to use in the office as it seems i cannot use an ordinary charger on newer s7 edge device. Am I right to say that the minimum requirement for power output for s7 edge is 5V 2A? It doesn't matter to me if it is just non-fast charge as I normally on my desk all day so non fast charging is okay.
Please help. I need an advise for this.

So we just upgraded to Note 3 from our galaxy 3 (wife and I)...
I noticed the charger is a 2 amp charger compared to the SGS 3's 1 amp.
I started reading some threads here and found out the USB 3.0 cable will not charge the phone faster unless it's plugged into the computer.
Apparently the PCM also limits the phone to charging at 900ma. (not verified)
so I'm curious now.... at what amps does this phone charge? I'm trying to get a spare charger to keep in the car, and also trying to get a usb car charger if I can benefit from the 2.1 amp one instead of the 1 amp one that's in there now....
Can anyone tell me if I should get a 2.1amp charger or stick with 1 amp chargers as the spares if it'll still charge at 900ma?
I'm using USB 2.0 cables btw. (unless I can charge faster with the USB 3.0 when plugged to a car charger or the wall, which I apparently won't from my research here)
While I await for responses, I will plug the charger into my voltage/amp reader and we'll see how much power is being drawn, which might give an idea as to how many ma it's charging at.
For whoever that wants to know this information, these are my findings from my meter that is able to measure how much power is being drawn (kill a watt P3)
with the stock charger and USB 2.0 cable (3.0 made no difference) the phone will charge at 900ma with the screen on. If the phone is shut off, or screen is off, it goes to 1500ma. Very steady at those.
with the SGS3 charger that I had, it's a constant 900ma whether screen is on or off... (1.0 amp charger)
now I guess I will have to see if this is the case with any 2.1 amp charger, or if it's specific to samsung's charger with snapdragon's quick charge feature. I believe only certain chargers allow use of this.
I don't know, I'm getting 1800mA by using stock wall charger with USB3 cable and 450 with USB2 cable. I know GS3 would charge at faster rate when using original Samsung wall charger and cable, which had data lines shorted, not sure if it's the same with Note3.
I don't remember for sure, but I think charging rate from computer was pretty much the same 450mA regardless of USB3 or USB2 port or cable. I remember this because I was surprised they didn't take advantage of higher power ratings with USB3, but maybe it was just my particular setup. I used application that shows charging rate, so all is with phone on, but it makes perfect sense, about 2 hours from 0 to 100% charge, if you allow some extra time for trickle charge at the end, losses and usage.

and how did you measure this 1800mA?

program is called galaxy charging current, you can get it in the play store.

You can't compare that app to a meter that shows you the actual current being drawn

why not? How do you think your meter is working? Phone has similar IC. How did you come up with your numbers first of all? I thought you plug Kill a watt into outlet and it shows what the charger is using at 110v and at about 10 watts(or is it 220-240v for your location), your unit maybe at the limit of accuracy, since the amperage would be somewhere around 100mA, where your device is designed more for larger power consumption like fridge or TV running 300-1000watts and few amps. Is your unit somehow capable of measuring what the charger is outputting and if so, how?
BTW you can't get more than 900mA from PC even over USB3, thats the max limit.
I checked again: galaxy S3 wall charger is giving me 600mA, Note3 charger with USB2 cable gives me 1200mA and Note 3 charger with USB3 cable pumps out 1800mA, computer USB gives 450mA regardless of computer port, but there is something wrong with the USB3 cable that I got, is not connecting properly and I have to wiggle it to connect so maybe bad cable is the reason I don't get higher charge rate from PC USB3.
I just got a new car charger which has two ports. 2.4A and 1.0A. The 2.4A is "designed" to charge tablets and 1.0 is for phones. I bought this thinking that it would charge my S5 faster, but it doesn't seem to charge at all. It charges all other devices like my iPad, tablet, iPhone, etc... but not the S5. Does the S5 have some amp protection, preventing it from being charged by this?
it doesnt charge my girlfriend s5 too . i bought a power block which have 3 2.4a port 1 smart usb 2.4a and smart usb 1a it will only work on the smart .
i tried charging with ipad charger dont work . portable charger that is 2amp it work. Note 2 stock charger work too . the verdict i have is you cant use any charge that is above 2.0a.
Not true , I charge with my iPad charger just fine.
Also I'm pretty sure the charger doesn't push 2.5amps,
It just means it should be capable of supplying that if the device tries to take that much.
The device plugged into it only draws the current that it can.
What CAN happen with portable chargers is that when the phone nears 100%, it goes Into trickle charge mode with low
Current, and then the portable charge thinks it's done charging so turns off, and the phone never hits 100%. That's why they have a special port for android/iphone on some of them.
@f1ux
Are you using stock kernal or custom ? because seriously i tried for the whole day . it just cant work. i am on lastest stock fireware and kernal SG.
It worked fine with stock straight out the box last week and at the mo it's running 0x0 rooted
I charge mine with dual port car chargers 1a and 2.4a regularly. 2.4a is much faster. But I'm not sure if one or the other has an effect on battery longevity. Stock S5 out of the box with Rogers.
so i lost my fast charger which i didn't didn't use anyway as i kept fast charging unchecked in phone settings
now i got a new romoss charger which is a good charger AFAIK. it is rated at 2.1a, plugged it in and it took too long to charge. i downloaded an app called Ampere to measure the current and the maximum it gets is about 1000mA.
i thought the new charger was ****ty so i tried my friend's LG charger 1.8a and got the same results. tried another 2.1a samsung charger and nothing exceeds 1a.
is it something wrong with my phone or is it software related?
i'm using eRobot's newest rom with spaceX kernel (also tried googymax and suemax kernels). tried to check the fast charge option and again, same results.
any opinions or thoughts are much appeeciated
thanx
You need a Qualcomm Quick Charge 2.0 compatible charger in order utilize adaptive fast charging on your Note 4([email protected] & [email protected] output). Buy new Note4,Nexus 6,Motorola X Style charger. Also make sure your USB cable is undamaged/good quality, since not all cables actually support fast charging.
i dont need to use it as a fast charger, i just want it to charge with 5v 2a which the chareger is capable of
Okay, so if I use the yotaphone 2 charger, I get rapid charging (green charging icon) and high current 1.5A+. Sometimes this heats the phone up fairly hot. I am measuring this using the app Ampere.
If using any other charger its very variable, I get something between 100mA and 800mA charging, even if the charger supports higher charging rates. Now I know the yotaphone 2 communicates via the usb connector with the genuine charger, as I was using magnetic usb cables which can connect either way around. One way around the data pins are connected and the fast charge mode works, the other way around the data is not connected and charging is limited to the lower current. Caution with these as the type I was using ebay approx £4, cannot carry the 1.5A charge and the magnetic charger plug itself heats up.
Question: What charger do you use? What current is it capable of delivering and does your yotaphone 2 use this current. How long does a charge take on various chargers?
I can't recall correctly, isn't the stock yota charger 1.5A? So with 1.5A the phone itself consume 0.7-1.4A, what you get is correct with 0.1-0.8A. I use the Asus Nexus 7 2.1A charger, it charge at 0.4-1.2A. With screen off and sleep mode it will charge faster!

Using s8 fast charger it is rated as 5v , 2a im worried as is dont have lg original charger which supports 1.8a(fastcharge). My phone also got hot on samsung adapter . Should i buy original or its nothing to worry about. Kindly need advice.
AFAIK, there will be no difference. The chip controls how much energy is delivered to the battery, and even if you use a 3a charger, the phone itself will limit the maximum energy delivered so it doesn't affect battery.
It's normal that the battery gets hot on fast charge (even in normal charge) Just try to avoid using the phone or charging in a hot environment so the battery doesn't go further than ~40°C more or less.

The original one is 9V 1.8A so there won't be any problems with the Samsung one.
