(Q) Anyone tried wall charger from Galaxy Tab? - Galaxy S III Q&A, (US Carriers)

Wondering if anyone has tried it? I remember reading that the wall charger from my Tab 10.1 was more powerful than for the phones because it would take FOREVER to charge. Wonder if it's compatible with our S3?

Anyone?

I believe that anything that charges on USB is just getting 5 vt, so any charger would work with any phone/tab if it is charging through USB. I would guess that the wall chargers are also putting out 5vt and would therefor be fine with any mini USB plug charging device.
Easy to check, plug it in and see how it works. (Buy insurance first )

Yes,
I have been using my tab 10.1 charger since the first day I got my sgs3.
It DOES charge faster, about an hour for a full charge from <8%
No problems I have noticed, and I am using blazer rom.

An hour, eh? Nice. I thought it would charge faster but not that fast.
And im definitely talking about the using an outlet, not usb.
Thanks for the confirmation!

No problem,
I knew you meant the AC charger, and that's why I posted. USB charging is slow until someone adds in the fastcharge ability to a kernel for our s3's
Glad I could be of help.

Not talking about blackberry either. The wall charger for the Tab is more powerful than phone chargers. Thats the only charger im asking about.

Any modern device will limit its own current draw to what is needed to do the job. While it is certainly possible for a charger to be underpowered resulting in slower charging it should not be possible for a charger to be overpowered. That is, there is some maximum charge speed the phone is capable of and that limit is expressed as its maximum mA draw. a charger that sources under the max mA will be slower than one that meets or exceeds it. A charger that exceeds the max mA will not charge any faster than any other charger that also exceeds the device's max mA regardless of the differences in their source capacity.
So, if that makes sense to you then you should know it ought to be safe to use a powerful charger and that if faster charging results then the stock charger is in fact underpowered for the device it was paired with.
Disclaimer: Any engineer worth his salt is going to current limit the charging circuit on the phone. However, if this were not the case then providing increased charging capacity will most certainly damage the device.

Basically youre saying the phone itself wont pull in anymore draw than it knows it can handle. So I guess if it does charge faster than great. Long as it dont fry im happy!

Slow charging?

I don't know if it's a kernel/rom problem, or a hardware controller that's at fault, but ever since I got this phone charging in car chargers, computer usb outlets, and even alternate wall chargers has been painstakingly slow!
It takes forever to charge, and takes a dedicated powerful wall outlet to even do anything.
Anyone else experiencing this?
The default Samsung Provided Wall outlet charger provides .7A of power, while USB provides .5A of power max. Also what percentage do you charge it at, and can you take a screenshot of your battery usage graph?
The 3rd party chargers that designed for iDevices are not recognized as AC chargers and will be charging at USB mode which is much shower.

According to Entropy512, here is the quote:
Improved battery charge algorithm for faster charging - Initial research indicates we have an alternate battery charger chip (MAX8922) that differs from the MAX8997 used in the I9100. We DO have an 8997 also - but on our device for some reason Samsung decided to use an alternate chip instead of using the 8997's built-in charging. This means we have far fewer options (90,400,660 mA) in terms of charge rates compared to the I9100 (from 200 to 950 in 50 mA steps). So we might not be able to implement any fancy charging algorithms.

So if I am understanding correctly we were limited to 660 mA at max and unless some way to change it is found, there is unfortunately no use from more powerful chargers .

Perhaps you have either a faulty battery or a faulty charger.
Here is a link where you can buy a new battery and wall charger for under 8 bucks for both with free shipping!
Check it out here: http://www.ebay.com/itm/1800m-BATTE...045605?pt=PDA_Accessories&hash=item43aa9a4465
Put your phone in to power saving mode and see if it charges faster.
Other wise exchange it under warranty.
I've experienced that this devices charges significantly slower then my previous devices.
I found it odd when I saw the stock a/c USB adapter outputs at .7mA so i did a starch and found an article out there with a statement from Samsung stating that their devices are designed to charge slow because it's healthier for the battery.
I don't know if the charging current is restricted by some code in the kernel or a physical chip in the main board.

It is true that slow charges do increase the overall life of the battery. Also not charging it all the way or discharging it all the way will keep the life of the battery. If you discharge the phone all the way down, it will take much longer to charge than charging it back up from 20% or so.

Physical chip. However on other GS2s and original GalaxyS phones, the chip was fairly controllable by the kernel.
Ours isn't - it has three settings. 90, 400, 660 mA.

Bigger charger, faster charge?

Hey guys
I was wondering , since it takes this phone over 3 hours to fully charge... If I buy a Nokia charger with an output of 1.2 mah ,would it take a shorter time for this phone to charge? Its own charger has 0.7 mah output..
No. SGS2 has a capped charge rate of 650 as far as I know.

Charging is controlled by the phone only and varies depending on whether it detects a USB data link or not. And the battery temperature.
So, provided the charger is rated at 700mA or greater, the phone will charge at the fastest rate it sets. On USB, the charge rate is lower. USB 2 ports have a maximum of 500mA output... and if the phone is on, the charge rate is often lowered further.
I use an iPAD2 charger for convenience, which is rated at 2A. The phone charges fine, but only at the same rate as the stock Samsung charger.

In my ROM there is an option to enable fast charging. If you enable that, a charger with a higher mAh will make sense.
Probably the heat issue is the main reason for not implementing a higher charge rate. Battery degradation world be another.

[Q] How to solve battery discharging while car navigation?

Always when I'm using my S3 with Navigon, it discharges when connected with car charger.
I am using an original car charger by Samsung. Rom is in signature. Temp when navigating is around 48°C.
All of these things just let the discharging cycle last longer, but it is not gone. I know the problem from S2, but nothing helps on my S3. The problem just exists with Navigon.
What I tried:
- different charger
- set CPU freq to max 500 MHz when navigating
- Display brightness to min when navigating
- Set AC in Extweaks from 1000 to 1200 for testing purposes
Any suggestions from experts?

I actually have the same issue on both my GS3 and Galaxy Nexus. The problem here is that the car charger is not able to provide charge to the phone at the rate at which it discharges. So it will keep discharging unless you get a charger which can charge at a faster rate (higher the Amp, the faster it will charge).

I am having the same problem and I just talked to a buddy of mine (who is an electrician) and he told me that the charger needs to be the exact same volts(not amps) as what the phone/battery needs. If the charger puts out more or even less it could harm the battery and even the phone itself. If I got this right my old charger was working at 500mah I think the s3 is supposed to charge at 1A.(if I'm understanding all this right) I was trying to use my old charger with my new s3 because they both use micro usb and I thought it would work. Well, it does charge the phone but doesn't charge at the rate required thus my phone is discharging faster than it is charging. I hope this helps and sorry if I forgot anything. Btw he has been an electrician for well over 20years. (I want to add I tried to repeat everything like he told me because I personally don't know much on this subject) helpfully someone else can explain it better. Good luck

I would have to agree with circuit89, you need a charger with higher Amps. All usb chargers provide 5 volts. as that is the sub standard, but a standard usb port on the computer is only 500mA, i think the standard charger that comes with the s3 provides 1A, and I think that is the minimum that you need to be able to charge while using gps etc.
A charger with a higher current will no damage the device, it just means it can provide up to that current, so it will provide up to as much as the phone can accept, or it's maximum output.
in short you need a car charger which provides a higher current to charge it faster so it will charge faster than the phone is discharging.

So if I understand this right your phone should be charging twice as fast( if it using the hole 2.1A) compared to the 1A charger that came with the phone right? Have you checked to see how long it takes to fully charge? I was thinking about buying a 2.1A charger.

When I want to believe BatteryMonitor, I am connected to AC charge with 1000mA, not USB. When looking on the consumption in BatteryMonitor when not connected and running Navigon, 1000mA should be highly enough.

I have the same prob. Charged about 7% in 30 mins (using the supplied charger). Charges fine when I use my N7 charger though. I'm gonna have to check the charger when I get home.
Just for the hell of it, here is my how my charge is going right now:
7% - plugged in at 3:22
21% - 3:31
33% - 3:42
44% - 3:52
57% - 4:04
83% - 4:28
For what its worth I don't have this issue with charging - s4 charges comparable to s3 HOWEVER i am not using stock charging that came with the box, I am using cables i have had from before and sometimes even use the USB to wall plugs from Apple and/or BB or whatever I have had lying around - seems to work well.
With a 5V 2 amp charger it goes like a bat out of he'll, using my thunderbolt's 5V 1 amp charger it's quite slow.

i have noticed that having it plugged into either a car charger or a computer, it does NOT charge very quickly... not to the point where it is annoying but, slow enough to notice a difference...
If i take the cable from the box and plug it into my USB hub (it has it's own power source also) if im using it for much other then file transfers i can still lose power off battery. It just seems to slow the battery drain instead of just charging slower then plugged into the wall with the 5V 2amp plug. Now obviously if I'm not doing much with the phone while on the USB it will charge but much slower then the wall charging

Ok, there's something else going on here. Maybe its software related.
My S4 will only charge fast on the supplied charger. The cable doesn't seem to matter; I tested a bunch of them. I have an assortment of other 2A chargers and none do better then barely keeping up with power useage; hardly any charging at all. Again, the usb cord doesn't seem to make any difference.
Now, I've read mention of a "fast charge" feature that the kernel developers are "turning on". I haven't found a good explanation of what exactly that means but it appears to me that Samsung tried to make the device only charge at the full rate using their chargers and at a minimal trickle charge rate for all others even if they are capable of the full 2A output.
Then there is the problem of buying extra Samsung chargers since there appear to be a lot of knock-offs that will not get the phone to charge at full rate.
What a stupid thing to be such a PITA.
Anyone have any solid info on this?
just about every samsumg device either needs a kernel hack or an adapter to get fast charge off of a non-samsung charger. you can grab a few of these:
http://dx.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
and use them with just about any 2amp charger with no problems on my old galaxy tablets or my galaxy note and nexus getting fast charge(nexus even charges faster on the 2amp - hope i don't blow it up!).
Fast charge from my understanding is just turning off the data connection when plugged into a computer. This allows for higher usb charge rates, it also helps certain wireless charging setups. I am coming from a gnex where this was the terminology, I assume it's similar. Fast charge shouldn't do much for you if you are having trouble with 2amp chargers, but maybe in this case Samsung limits through put when it doesn't recognize the charging unit? If fast charge tweaks somehow disable this, then I guess it's possible you would enjoy increase in charge rate though I have no verification on that.

There's a problem with semantics going on. Fast charge is exactly what you're used to it being on the GN. What's being referenced here is quick charge, a feature of later Snapdragon SoC's.
Sent from my Nexus 7 using Tapatalk HD
fast charging is rapid charge where near full power is transferred. in the gn2, gnote 10.1, gnex, and gtab10.1 the max i got was ~1600mA with all my 2.1A chargers including the samsung charger. the rapid charge continues to 90% and then switches to trickle - anywhere from 400-900mA til 100%. without the adapter you're stuck at trickle, even at under 90%. some chargers seem to have it built in to rapid charge,but most don't.
i've never gotten a full 2100mA from any charger yet.
you can find schematics on how to build your own adapter in one of these samsung boards. i think there was a very detailed one in the gnote10.1 forum.

What is the fastest charger for the S3?

I have an old 0.7A charger and was told that a 1A charger would be faster..
But how far higher can I go? Is there a 2A charger?

1A is stock for S3.
Maximum recommended is 1.5A,more may brick your whole device,if not the battery.

I guess using modified"boeffla or googymax " kernels will let your phone charge much faster
Maximum rating of the charger is irrelevant, the phone will only draw a safe amount. If you override that limit then you may blow the internal charging IC or rupture the battery.
Don't post questions in the general section.
The S3 can't charger faster than 1A, it will only draw what it can, I've used a HP Touchpad 2A charger since the day I got the phone, it still won't draw more than 1A. You can use custom kernals to draw more, but you'll find lots of stories of people who did it and fried the charging board.
I tested using 1.1Ah, and for the storioes I've read, it's the maximum value you can use with security.
Hi, you can have more than 1A, but you need to change the limit with boeffla (i made it for the USB charge)

I tried 2A once and it was fast (0-100 in 1hr) but its not recommended 1.5 max
Also I increased charging speed to 1600mah that time and it was working

Dramatically increasing charging current will also dramatically decrease battery service life
Just get a second battery and desktop cradle, instant recharging without any wear on the phone motherboard.

Hi, i am getting a new charger for my tablet pc which uses a 5.35V 2A output charger and was wondering whether i can use this to charge my galaxy S3. so that i do not have to carry 2 chargers?
IS it advisable?
My S3 came with a 1A charger, my wife's S3 came with a 2A charger. I used her charger a few times and it worked fine. As of last week my charger is working fine, if I use hers with my phone I only shows "USB" in the battery info and takes forever to charge. I don't know if her charger did damage to my phone/battery but that felt strange, so I stopped using her charger.
