Sony USB-C charger to improve the charging time of S8+ ? - Samsung Galaxy S8 Accessories

Hi!
I have a doubt, these type of USB-C --> USB-C charger can charge the S8+ quickly than the original charger provided with the device?
http://www.sony.com.sg/electronics/portable-charger-accessories/cp-ad3
I know that S8+ is not use the USB-C charging protocols and use Samsung AFC, because this my doubt if buying this will be a improve or only a waster of money.
Thanks!

I doubt that charger will be any faster than the Samsung provided charger.

Thanks, I get one to make some test. I install the Ampere app, I don´t know if this app is a nice measure tool, but is almost the same that original charger, also a bit faster. Original in test charger session show in the Ampere app a max of 990mA, and this Sony 1020-1100mA on different sessions on both.

I'm cool with the stock charger. I'm not trying to make my phone explode and burn my house down. I'll stick with Samsung's recommendation. Just because you CAN do something doesn't mean you SHOULD.

Original Samsung charger will charge your device at 9v whereas the Sony charger will only charge at 5v, however the new USB c standard allows 3A charging so the power you get from both chargers will be very similar. I use both types of charger and find it hard to find much difference in charge times. Ampere can't be used accurately as it's only showing the charge current not voltage and you need both to calculate power and compare the 2 accurately.

Maximum charger amperage?

Alright, so I have a mini USB car charger that is rated at 2.0A (got with GPS) and I just want to make sure the extra amperage is not going to charge my battery too quickly and then kill it in the process. All I have to go on is that my wall charger is capable of only 1.0A and the computer USB is on the level of mA. Does anybody have a car charger or know the maximum amperage possible that these phones can take?
Thanks in advance.
Its to Strong ! I have Crash a PDA with 1.5A
I've used a 2.0a charger but noticed that the battery didn't charge right.
On that note, also noticed that a .5a or 500mA charger after about 6 months killed my battery. (burned out and won't take a full charge anymore)
Recommendation is to stick to 1.0A charging as much as possible as the Wizard's charge circuit is designed at 1.0A charging and monitoring.
DOESN'T MATTER ..if u know the basic Ohms Law..its the max capacity of the charger.(or any source) the current regulating circuits will take care of the real charging current fed to the battery
I charge my phone on my computers USB connection all the time, all computers have a maximum of 500mA USB current.
Amps are pulled from the charger, not pushed to the phone.
Voltages are pushed to the phone, not pulled from the charger.
If the phone draws too much current from the charger, the voltage drops to a point where the maximum power (P (Watt) = U (Voltage) * I (Amps)) of the charger isn't exceeded.
According to the USB specification you need at least 200mA with 500mA recommended +5VDC.
More is never a problem, you could even use a 50A power supply without breaking your phone. Practically spoken: I wouldn't do that.
huh?
I have messed up a few devices before by putting the wrong charger on the device (2.0 amp charger on a droid eris and 1amp charger on the MOTOACTV) Is this a problem with the device's charging circuit? In general it should only pull up what it needs to charge but my devices were messed up?
I returned the first MOTOACTV after it wouldn't leave the boot screen and the second one I got acted funny on 1 amps as well. It charged fine on .75amp charger that came with the device but when I put it on my HTC Dinc charger it shot up from 10% to 20 to 30 etc. all within minutes. Hope I didn't mess this one up too.
Just trying to figure out what the deal is. My phone for sure charges faster when connected to 1amp vs .5amp (computer). This makes sense I understand because the device is able to handle 1amp, but I wonder if it would mess up with a 2amp charger.
Thanks!
The last two posts of 2008 are correct. Your phone is capable of drawing more than 500 mA but less than 1000 mA. If the charger is 1A, 1.5A, 2A, or 50A, it won't make a difference to the phone's charging time or life.
Wrong voltage can be bad, but phones are designed to support USB charging, as a minimum, and 1A to 2A is always safe. As was said in 2008, the charger pushes voltage to the battery, but the battery pulls current from the charger.
That's a really good way of describing it
Pushing and pulling current and voltage is a really good way of describing it.. Given that I am theoretically well within the charging parameters, how comes my phone (Galaxy mini/pop) becomes unusable when its charging (touch screen doesnt touch and screen jumps to new screen without touching?) Am I wrecking my phone?
No, your charger is to blame. Maybe it isn't properly grounded. Phones with capacitive touch screens (not the Wizard! but maybe your phone) can get really weird on some chargers. I have a Nexus One with an aftermarket charger that always makes the touch screen go haywire. When I use an HTC charger, the phone has no problem. As far as I know, the damage isn't permanent, it's just that the sensors get confused. When I disconnect from the charger, turn the phone off, then turn it on, all is well.
My wizards were never bothered by chargers, no matter what kind, as long as they were mini-USB, they were the right voltage. The wizard doesn't take as much current as more modern phones, either.
Hmm. Not properly grounded sounds very plausible. Viva mediterranean circuits. Thanks
Usb chargers will be rated at 5v, which is exactly the correct voltage to charge your device. What you want to make sure is you buy the correct "rated" amperage. Not because it will damage your phone. Amperage only exists as a sum of the power used by the device. You want to find a decent 1amp (1000mA) or higher if you wish, rated usb charger. The the mains charger for your phone is only rated at 1amp, so a 1amp charger is adequate. Avoid 500ma chargers as it will take twice as long to charge and gps / satnav applications will drain the battery even when charging at that rate.
Also if you have a new pc, most of the decent boards will specify 1amp charge even when off if it has on/off charge stated on manufacture details.
Newer phones will charge fine with higher amperage
The myth that charging your device at a faster rate will reduce the life of your device’s battery is false!
If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts higher won't matter.... These lithium ion batteries can handle it... It was just back then if you were to try to put a faster charger in an older battery it (in any cases) just won't charge.

Extended battery for the S7?

Any third party extended battery options for the S7? I prefer the slim version if possible.
Sent from my SGH-T849 using XDA App
I rigged up a battery pack using 4 rechargeable Energizer AAA's and just plug it into the DC power socket and double-sided taped it to the back of the unit
I imagine I could use some left over spare Li-Ion batteries from other phones though.
UPDATE: someone asked how
STEP 1: Buy something similar to this http://www.littlebirdelectronics.com/products/4%2dAAA-Battery-Holder.html
STEP 2: Buy a male plug that fits the female power socket on the S7 Like this but the correct size http://www.littlebirdelectronics.com/products/1.3MM-PLUG%2d2.5MM-SOCKET-DC-ADAPTOR.html
STEP 3: Solder them together so that the + and - charge come out of the same wires as the wall-charger
STEP 4: Plug in batteries
If this looks/sounds difficult, don't even attempt it, you WILL break your tablet.
Since the original battery do last too long, i found this 2 option that i think that work with S7:
Good price and free shipping
lol i cant post links yet, sorry guys...
here goes the links for the battery extender....

Nice guys! I was searching for an internal battery solution.
These battery packs look nice but be carefull, the output is only 500 mA. The S7 charger is a 2amp output charger. I'm not sure how well it will run on a lower input.

The DC pack will only feed what the unit draws, and I doubt very much that it draws the entire 2000mA.
I have rigged up a USB charging cable for myself, USB pumps out 5v at 500mA max per port (I'm only using 1) and it charges a little slower than from the wall, depending on which computer I'm charging from, but apart from that it works great still and I can use the same cable to charge from other USB-charging devices like the one I have in my car.
The 500mA output will just mean it charges slower, and seeing how it's only a battery extender (IE, the oem battery is still required) and not a charging solution (the S7 can run without the battery off only the charge from the wall), the charge provided will be fine for extending the battery life.

500mAh as supplied by standard USB will charge but as you say only slowly.
It will not start a charge if the battery has been allowed to drop too low. That's common with all Lion batteries and is why you get a high current wall charger to do the job.
If you are using the device at the same time (and depending on the functions in use and the state of charge of the battery) you will definately struggle with any positive charge and will experience heat build up in the USB port, cable and device so be carefull!
If you are also using the device as a phone and get a call there will be an extra high peak current draw that has to be contended with and that complicates things further.
With all the tests that I have done allong these lines 1000mAh is a bare minimum to cope with eventualities and even then it's borderline.
I have blown car adapter fuses and had low current phone chargers get really hot.
I now only use 2000mAH rated chargers.
Are there any? I would really want to have a battery that could last at least 6 hrs... Any suggestions?

That will give you about an extra 12-18 hours,
But no internal battery larger than standard. Why would you want one when the external packs are usable with any device and don't become redundant when you upgrade to a different model?
I made such a battery of two packages of Chinese Tablet battery voltage of 7.4V LiJon / 1500mAh connected in series and used a converter on the circuit LM2576 (with car charger navigation) [//chomikuj.pl/wibi) -> Huawei Ideos S7/Dodatkowa bateria].

[Q] Max current allowed to charge the S3

Hi,
I've read some threads here about charging the S3, but not all is clear to me. I would appreciate some explanation:
1) I've read that the stock chargers output 1A. However, on the charger I got with my S3 it's written "output: 5V 0.7A". So do you think I somehow got a wrong charger?
2) I want to buy a car charger for the S3. There are many generic car chargers in ebay, some of then output 2A current. What is the maximum current allowed for the S3? I couldn't find this number in my S3 manual or on the phone itself. Will a charger of 2A cause harm to my phone? or to the battery? or to both?
Thanks in advance!
bump... does anyone know?
My charger output states .05v=1.0a.
As for what aftermarket charger to buy, I would stay away from chargers with more output than the official for 'peace of mind that my charger's specifications are the same as the official charger that came with the phone' reasons.
Cheers
Generally wall chargers output 1000mA (1A) and USB ports 500mA (0.5A)
You do not want to purchase anything that goes above 1000mA

I attach a picture of the adapter I got with my S3.
It says 0.7A on it, while it appears that other have one with 1A.
Did they con me with this adapter?
And regarding the maximum current allowed: do you think an adapter of 1.2A might harm the S3?
Do not know where your S3 come from but this charger is not made For S3 but for S2!
I just checked the model number:
S3 charger: ETAOU81EBE
S2 charger: ETAOU10EBE (like yours)
And there is no cable on the S3 charger, it use the USB cable
Thank you for this!
I don't get it. The charger was inside the S3 box and looked original. Damn!
I think the store I bought from import their S3 from Germany, since it came with Vodafone German stock ROM. Is it possible that this is the charger they sell on German vodafon? Or perhaps the store switched it for some reason?
Mine also come from my carrier: french vodafone
Was your S3 box sealed?

Hi,
Background - I am an electronic engineer and have designed power supplies.
The Amp rating on a power supply is it's maximum capability to deliver power. The Voltage is the 'force' that it can push electrons through the device, this is the important one to have correct. So a 5V 300A Power supply will not charge your S3 any quicker than a 5V 1A power supply.
Get yourself a 1A car charger and you'll be fine. Depending on how the data pins on that charger are configured it'll be recognised as either a fast or slow charger but it will be fine in any case.
So, according to what you say, there should be not problem to use a 5V 2A charger on the S3?
The charger cannot accidentally push too much current to the device?
No. The phone limits the Amp the battery can get.
It simply won't go above 0.5 or 1Amp depending on what resistor is coded between the data pins (the 2 middle pins on the normal USB-plug)
(Note that this does not extend to all devices. E.g. cheap chinese toys and their batteries may not have any current limter, connecting them to "too powerful" chargers will result in damages or potential blow-up of the battery. The same applies to batteries without any electronic such as car batteries which can overheat and "cook")
I bought S3 in Germany 1.0A, there is a date on the charger:18.05.2012

Hi burmo,
An interesting concept. I have no clue in these things but what you say is not clear to me "all the way".
Charging my i93100 phone with 5.0V 3.1A will do no harm because it won't "push" more than 1A anyway?
And who is "responsible" for controlling this "push" the charger/battery/phone?
Does it work the same for Car chargers?
Thanks a lot,
Izik

so i have been wondering about this as well because i am currently building a custom charger for my s3 that charges the battery without having to plug into the charging port. i have redirected wires from the wireless charging port to metal tabs i have place on the back of my phone. it is a "drop in charger".
Anyway i have tested the charger that came with my phone. I also have the samsung stock charger that say the output is .7amp but after testing it with mutimeter, i have found that the output is actually 1.2 amps. As for max charging amps, I am not sure. I have tested several chargers. The new S4 charger puts out 2.34amps and i have not found any problem charging my s3 with it.

As far as I know the phone limits it so as you've found yes you will be fine
My original S3 charger is 5v 1.0amp
My original S3 charger is 5v 1.0amp. It was bought in Thailand with the phone.
I agree with burmo an advanced phone will have a current limiter as part of its circuit, however I prefer not to rely on it and not to exceed the manufacturer volt/amp recommendation.
The phone controls the current. In custom kernels (Boeffla and so on) you can change the target current. The phone has a protection built in, if the voltage is unstable (drops to much) it lowers the current untill the voltage is stable.
A HTC One charger I sometimes use (0,7A rated) only delivers 0,8A. A aftermarket charger I own (1,0A rated) is fine delivering 1,2A (modified target current, not stock). These charging currents can be read by various apps.
Get yourself a 1,0A rated charger and speed up your charging time.

Seconded the post above being an electronic engineer as wel.
Voltage should be exactly the same as you need, but this will always be the case for a USB charger.
Current should just be enough or more.
The charging current is dictated my your phone and not - and I repeat - NOT by your charger!
mine rates at 1A

Is it possible to see how many Amps of power are being provided?

Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.

[Q] Galaxy S4 Fast Charger

Can the charger bundled with the Galaxy S4 'fast charge' other phones, or is it something to do with the phones/batteries themselves that allow the quick charging? I heard that the charger charges at 2amp as opposed to 1amp like most chargers. I dont want to explode someones phone battery because it cant handle being charged that fast, lol

Using a 2A charger on an older phone won't hurt the phone. The phone will only draw 1A or however much current it's setup for, even if the charger is capable of delivering more.
Other devices will pull the full 2A from the charger if they can detect that the charger is of the right type to deliver it. Different chargers tell the device that in different ways. Apparently, Apple tablet chargers put a certain voltage across the data pins. Samsung high current chargers supposedly put a different voltage across the data pins. That is how the phone or tablet can tell what kind of charger it's connected to, so they will know whether to pull 2A, 1A, or 500mA (or whatever).
