I been looking like crazy and all I found were as high as 850mAh for the Droid Charger. Anyone found any other than the Stock Charger?
I use an old Nokia wall charger. The output is 550 mA. It works just fine. The way I see it is that its a higher output than just charging it through a computer and less than the stock wall charger.
The slower you can charge a Lithium-Ion battery, the better.

I need the faster you charge the lower the charge and wears out battery faster
if you do want a FAST Charge, then you got it with high output it'l kill your battery but.. there is an upside.. if you charge on fast charge..
then drain it 15 precent charge again you'll have similar effects of a long slow charge

I use an old Motorola charger because the cord is longer... charging it on the computer USB takes FOREVER!!! It is from a ROKR E8 and I think it says 650mAH The stock charger that came with the Slide is 1A and my GF's charger for her CLIQ XT is 850mAH.....
I use them all, does it really make a difference?
And how so I condition the battery because I get horrible battery life

i'm reading different opinions about this when i searched through the xda forums and on google.
i'm using the same custom rom and kernel for about a week now. a few days ago, i charged purely on wall socket. left overnight, my battery lost only 2%.
last night, i charged my phone when it was about 30%. i charged using usb up to 85%, then i finished it off on AC up to a 100%. my overnight loss went up to 5% (i did not install any additional apk, or change my setcpu profiles, etc).
there are no topics on this, specifically for SGS2. mostly are from HTC threads.
from what i learned, usb's only pour out about half of what AC's can give (500 mah vs 1,000 mah). does that translate into a poorer batt life?
How you charge your phone, usb vs AC will not effect the battery life, 100% is 100%, it will just charge slower via usb.

I have noticed something similar with my captivate.I would guess that when you use the wall charger with 1amp the battery gets more of a charge than when you use a usb charger at .5amps. 1amp can cause more chemical change in the battery than half an amp.
sent from my Infuse at Tranquility Base.
SGS2 will only let 650mA into the battery, AFAIK it's hardware restricted to do this. Wall charger will charge faster, but only slightly.
I see no difference and 2% to 5% is within a tolerable variation of overnight drain .
Its all the same electricity .

Firmware, actually, and the phone determines how much it will draw based on the resistance between the two USB data pins. If the resistance is < 200 ohms, it assumes it's plugged into an AC charger, and will draw up to 650 mA. Otherwise, it assumes it's plugged into a PC's USB 2.0 port, and will draw up to 450 mA, just under the 500 mA that a USB 2.0 port is supposed to provide, per the USB 2.0 spec.
Since it's firmware, it should be possible to change the current draw by re-compiling the kernel sources with new values. Note that you don't want to go too high on the charging current, as that could cause overheating or fire.

And how about charging a spare battery using a separate battery charger?
I have two batteries and I never charge them plugging the phone, just using a spare battery charger. Does it have any negative effect on the batteries' lifespan?
dont know what happened but my phone is being charged with ac adapter as same speed as usb.(more than 4 hours) :S
I have a USB charger capable of delivering 1A.
Even with the data pins shorted (phone side), it still seems to draw only 350 mA :-(
Any ideas?
Known made-up cables that do work?
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.
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.

Correct me if I'm wrong but I didn't know fast charge was Kernel specific. Thought it had to do with the cable and plug in?
Any-ways, my two cents are no there is NOT.
With the fast charge app that looks like a battery it is kernel spefic. When u run the application it will either work or say kernel is not supported
The output of a typical computer USB port is a half an amp at five volts DC. If you get a charger, wall or cigarette plug, that is meant for an iPad, it will output 2.1 amps at five volts. It's best, for the battery life and phone, if you don't use a modded kernel for fast charging. Batteries last longer, overall life before replacing them, if they are slow charged. Heat from rapid charging will reduce the overall lifespan of a battery. I'm talking tech like in one hour or less chargers for AA batteries but it still holds true for lithium ion. Heat and hitting a battery hard with an aggressive charging circuit will kill a battery faster. My suggestion is to use a charger that has a max output of 2.1amps, like used with the stock and iPad chargers, to recharge the battery if you're impatient. Better yet, get an official Samsung external charger with battery so you can rotate batteries and have one charging or charged without forcing yourself to have the phone tethered to a charger often. There have been high profile instances where extended capacity batteries have burned up a phone, when charging, because the electronics of the battery were crap or the cells were of crappy quality. Be safe, be smart. Samsung OEM batteries might be expensive and low run time, but they won't usually cause a phone to go into meltdown mode because of their subpar electronics or cells.

there's no way to disable that if you use the original charger of V10, they are rated to charge as fast as they can...you need to use another charger, i recomend you use a 5V 700mah max amperage and if you dont bother to turn off your device after plug it because your battery will get a good calibration and last a little bit longer, for sure a full charge with 700mah charger take almost 3:30 hours but it will make difference, trust me, i do the same with mine at least 1 time per week.

you should use at least a normal 2A charger. As you for sure know amps a drawn by the device connected to the charger and the V10 pulls up to 1.5A if the battery is lower than 30-40%. Using a 700mA charger might kill your charger after some time.

trust me, slow charging dont kill charger or the battery, i do this since 2013, i do this with LG 4X HD, LG G2, LG G3, G Flex2 and now with V10 and nothing have happen to my devices, i know what i'm doing, i am electronic technician and i know what i do.
