I would like to find a high output charger that is compatible with the Atrix. I know that some phones will limit the charging rate with unofficial chargers but I do not know about the Atrix. What rapid chargers have you had success with?

If by that you mean a charger that you connect to the phone, I don't think that will work. If you really want to charge your battery quickly, you will very likely need an external rapid charger (so you take the battery out, put it in the charger, then when it's charged put it back in the phone). However be aware that rapid charging usually comes with a price - by charging the battery quicker you shorten the overal lifespan of the battery.

Sorry if I was not clear enough. What I mean is a high output micro USB AC charger for the US.

I'm using LG OEM charger which output at 1A. much faster than Motorola OEM charger
im using a Nokia N900 which outputs at 1.2A its fater but i have to do a battery pull so it resets stats correctly
It all depends on the mA Number on the charger. Lookout for 1A at least and you ahoul be fine
China's charger will void your guarantee term.. Are you sure to want It?
You must be aware of your battery because faster charging (more output Amperes than stock) may damage your Atrix!!

No, it wont.
I use my TouchPad's charger putting out 2A, it works just fine. I use it for my bluetooth, phone, touchpad and kindle. I use it because it's convenient, one plug/wire for all devices.
A device will NOT charge any faster or get damaged by making more amps AVAILABLE at the source. A device will ONLY draw however many amps it needs, not more. This is the reason why you can replace a 100w bulbs with 60w or 13w CFL and not have them burn out. The voltage remains same, just draws less current (amps).
Like ravilov said, you'll needs something external. Even then I'm skeptical. The faster you charge a battery, the faster it will drain, at least with our type of battery.

One thing you might want to know is that the Touchpad's Charger is a different 5.3V, when compared to the standard 5V USB. Just something I thought you should know.

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.
Sent from my SAMSUNG-SGH-I777 using xda premium
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.

Also just to double check, it does not charge a docked device, just the spare battery?

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.

I'm looking for an external battery charger (preferably solar powered) for taking my Note on backpacking trips. Unfortunately, most of the solar packs that I've found have only .5 - .7 amps available for USB output. If I'm using a 1amp charging cable (with the data leads shorted), will .7 amps kick in the AC charging speed? Is .5 amps enough to charge the phone while I sleep for 7 hours?
I suppose it depends on how long you are out without power but another alternative is an external battery that allows you to charge your phone by plugging it into the external battery.
This one here (at $75 USD) will let you charge the Note from completely dead to a full complete charge 4.4 times.
http://www.amazon.com/New-Trent-IMP...Z64Q/ref=sr_1_2?ie=UTF8&qid=1336084828&sr=8-2
So, if you started your backpacking with a full charge on both the phone and the battery pack, and assuming you charge the phone every night at say 20% battery left, you should get 6 days. If you need more than that, you can just buy a second battery pack (personally, Id want to have two just in case).
That's a good suggestion from littlewierdo. I would also have at least 2 spare batteries for the note. I don't think that .5 amps is enough.

Budge I had an HTC evo 4g and got a 5400mah battery. This worked ok. However the output is .5a which will not charge the note if you are using maps with gps or bluetooth or playing tunes. It wil charge when not using those. Say at night when you are asleep. I think you would have to find a battery with output better than 1a to actually charge when you are actively using your phone. I am not sure of the actual output you would need. I will research it though for my own needs. I do use my note on my motorcyle with a charger which outputs .5a and this is nowhere near what is needed to use google maps and bluetooth and play tunes.
I am actively looking for a solution which will charge my note while using google maps, bluetooth, and playing tunes etc. I may have found a solution with a usb y cable which is connected a 2a source and a .5a source on my motorcycle.
The only solution for backpacking may be to charge when not using the note. I am fairly sure it will charge at .5a when sleeping.
Good luck.

Im not sure where you got the .5 amps from, it outputs 1 amp, so it will charge the Note with the screen on. However, it wont charge quite as fast as the wall charger will it will actually charge the phone.
It should be able to handle keeping the screen on, bluetooth doesnt use much power at all so playing music shouldnt be an issue and gps uses very little battery as well. I dont see an issue with it.
Admittedly, I dont have one of these, dont really have much of a use for one at the moment but I cant possibly see any issues with this.
HOWEVER, there are alternative external battery packs that are MUCH cheaper with less mah capacity (meaning, in simple speak, you would get less power storage meaning that you wouldnt be able to charge your phone as many times as you might like). There are other USB battery packs that might also have less power output (or more) which might mean that you wouldnt be able to keep the screen on AND charge the phone.
Truth be told, I only looked for the highest capacity battery pack given what your situation was AND I tend to buy higher end if the price makes sense. In the case of battery packs similar to this design (external usb battery packs), they generally start at $30 and go to about $80 so buying the best possible makes sense. However, if the highest/best possible was $200, Id probably get something cheaper, but since its only ~$80, if I were in your shoes, that would be my choice.
Id probably consider getting two of them (that is, if we are talking about longer than 1 week excursions, if under a week, just get 1) and a decently long usb cable (3-4 ft) but not too long (you dont want to be tripping over the cable but you need it long enough that if you need to, you can charge the phone mid-day while hiking).
You dont need multiple batteries for the Note, the whole point of this external battery pack is to eliminate the need for them.

littlewierdo I was not necessarily speaking of the device you suggested but one I had. I was warning Budge to be careful and not get a device which outputs only .5a. I was suggesting that he find one which will put out 2a if such exists. The device which you suggested will put out 1a. However I don't believe this would be enough for my purposes and maybe no Budge's either. i was not refering to your device or you. Not my intent to get in an argument with you but to help Budge find a suitable solution.

Littlewierdo- I didn't disagree with your suggestion to use another battery pack to charge the existing battery. In fact, I have one and use that option myself. I was adding that it may be a good idea to have a spare. I was responding to the OP who mentioned .5 amps. I assume that's where imesg was coming from, too.
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%

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.

Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

If you want proper charging, then always use the accessories coming with that product. It is tested for sure and good. Other than that, you can use any charger delivering the same charge. The original charger is 5 volt, 2 Ampere. Don't use anything above 2 amperes as it may damage the device. Below that will charge it slowly.
BTW, why you don't want to use the original charger?

Can you test it with ampere (free in gplay) i don't think it will charge over 1800mA so that it acts like a normal 2a charger
Fast charging
Using a fast charger will destroy your battery faster. Not recommended as the battery is not removable. You can get a battery and if you are comfortable removing the back and swapping it out then go for it.

that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.
Since battery is not removable be careful with fast charging, since it will decrease the life span of the battery and in the end it will just give you less battery performance.. it is stupid... however.. there is situations where it can be really needed though but not on a regular basis..
Last weekend I would really had needed fast charging.. It forced me to spend about 3 hours on a cafee so I could make it 100% so I did know I did survive the day with gps and all other things.. However in these situations I really like the ultra power saving mode..it saved me that night.. when I was lost in stockholm.. and my phone was really the only way to get contact with people

Why don't you buy a powerbank? I can advice you the xiaomi 16000mah. That one charges fast and you can be mobile.
Any recommendations?
I wonder if a S6 charger do the trick. Stock charger is too slow damn. Spending 3 hours to have a full charge is not acceptable for me.
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps. Batteries will automatically lose cells from charge cycles and by the time you feel the effects of the battery going bad, you would have already moved on to the next device for the next person to worry about. And saying to use the Stock Charger isn't really good enough as the Stock charger doesn't serve as a Car charger also. If you want to charge your phone quick, and you already have a 2 Amp charger, Check your microUSB cable. Don't use junk cables, buy quality or use the cable you received with the device. You get what you pay for. Fast Charging won't work as the Charger has a chip inside that communicates with the Phone and Device. Also, when buying a charger, don't just randomly buy a charger online, Make sure its UL Tested. Even if it says UL tested, there should be a test number on that UL Label, take it a step further and google it and make sure it matches the charger specs and passes as knockoff chargers are notorious for copying other chargers Regulatory icons to make it seem authentic. You don't want to buy a junk charger that ends up burning your house down or gives you a very bad 120 Volt shock through the microUSB cable that would also kill and fry your phone.

Hi,
that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.

so much misinformation

You have not read my earlier post or you did not understand it. Changing the charger on the Mate 7 will have NO effect (zero, nada) on the time required to charge your phone except the charger delivers less then appr. 1.6A. Then it would take longer and evetually kill the charger. The Mate 7 uses a Kirin chip which has no fastcharge implemented. Samsung uses Qualcomm Chips with implemented fastcharge technology. The charger (in fact a power supply) and the phone/CPU/charge controller need to communicate with each other, otherwise fastcharge will not be activated (the reason fastcharge with charge-only cables does not work because they lack the required data cables for communication).
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps.

Wrong. Correct would be "I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v." The amps of the charger don't matter at all -> amps are PULLED by the phone not pushed to the phone. You could use a charger with 100 or 1000 amps and it would not hurt your phone a bit as long as it is only charged with 5 Volts.
More amps (>1.6A) on the charger do not improve the time for charging one second.
1.6A is nothing. i use 2.0A and it still chrges 3 hours.

Yes, and that won't change one bit even if you use the best and most expensive charger and a 1000$ cable. The Mate 7 is limited by its hardware (built in charge controller) and pulls max 1.6A. End of story.
As long as you don't understand how charging works you will spend 100's of bucks for cables and chargers to no avail.
The only reason, why charging with some charges is quicker than with others is that those chargers actually deliver the amps they are supposed to deliver. There are a lot of cheap/bad chargers out there which are labelled with 5V/2A but only deliver a fraction of the amps. You can identify those chargers easily because they get extremly hot. I use a 2A charger from Aukey which gets only lukeworm.
