The Samsung charger adapter which comes in the box is very slow in nature. It take more than 2 hours to charge my phone. I was wondering if I can use the following Nokia brand chargers which are fast chargers?
Nokia Charger Adapter CA-146C
Nokia Fast Micro-USB Charger AC-10
It won't make any difference the phone decides what current it draws from the charger, so it'll take just as long to charge.
Are you really sure about this? Can you link me to some articles which confirm this.
Even I was thinking about purchasing AC-10 charger from Nokia.
How fast is the nokia charger?
0-10% -> 100% in an hour or less?

I'm not sure about this. I have a friend with a Blackberry Playbook and he reckons his phone charges much faster if he uses the charger from that.
The "stock" S2 charger is 700mA - it doesn't take a genius to work out that for a 1650mAh battery this will take about 2.5 hours to fully charge the battery under ideal conditions (phone off) or anything from 3-6 hours with the phone on, depending all what's running or if you're using the phone while it's charging.
Which is all pretty ridiculous - ok we're comparing apples and oranges when we compare a S2 to the likesw of a Nokia, but I do miss the days when I could charge my phone in an hour and have it last two or three days. I thought my Blackberry was bad but at least I can usually squeeze a full day out of it...
The only wall wart I had lying around that was more than 700mA was a 5V 2A supply. I've tried with that which works, but the phone chokes with a "battery overtemp" warning after about 10 minutes - which tells me I AM pumping more into the battery than it can handle. This would suggest that there IS a happy medium where we can optimize the battery charge time - I'm bust looking for a 1A supply...
I have TWO AC-10Xs, and am using it with the Ninphetamene kernel (which comes with increased charge input mods to 800ma) fine. Charges to full in about 2.5-3 hours.
I've never gotten overcharge errors either.
Hi,the usage of more powerful charger will eventually reduce lifespan of your battery. This comes from basic physics, materials and so... Higher mA means faster current, which wear the material of the capacitor - battery.
I have capdase 2 USB car charger that was used for my old iphone device.
It outputs 1A.
is it safe to use it?
I tried to charge with it for 10-15minutes or so, and didnt recognize any suspicious warmups...it reached 41~degrees while at the moment im charging and using it as a hotspot and its on 38 degrees.

The phone (specifically, the kernel) limits charge coming in, and there MUST be hardware limiters on the batteries and the phone themselves (which, in some cheapo batteries DON'T WORK and results in them frying themselves and the phone in process) and the batteries are replaceable anyway.

i use htc wall charger rated at 1A and having no proplem with ,a pc USB port is capable of 1A and we all know there are no problem ,even so there are no visible improvement in charging time because as someone said the charging current is automatically regulated

That's good to know that the current is regulated by the device.
Is there a software to see what is the current taken by the phone?
As long ad the temperture isn't higher than 45degrees is it ok?
By the way, Im pretty sure that usb outputs 0.5A and not 1A

battery monitor widget
It seems logical to be able to use all chargers as smartphones all have micro usb .
(I 'm not sute that's mean something in english, sorry)
Great widget! thanks.
I really like the data it gives!
Sadly, while charging with my .7A original charger & meanwhile giving a hotspot to my laptop, it shows that only 76mA comes in!
hehe, gonna take forever to charge the battery this way.
i doubt this. i'm still worried about the compatible problem~~~
After two days with the battery monitor widget Im affraid itself it drains the battery.
could it be it affects the battery?
settings are regular, it monitors changes every 60seconds
Let's see if I can help make things a bit clearer. Feel free to correct where I may be off.
The Nokia thing, it's not a charger. It's a power supply.
The "charger" is built into your phone, hardware-wise.
How can I prove it?
Take the Samsung supplied cable, plug it into your computer. You'll see that your phone is charging too. No, the cable is not a charger. Do you think your computer is a special built charger for your phone? Hardly.
The charging circuit is within the phone, and thus charging the battery when there's available power.
Ok, so we have the charger (i.e. the mobile phone), we have the battery, we need the power. Where do we get power from? The wall adapters (or computers). So what are the wall adapters? Ratings of 1000mah means that the wall adapter can provide up to 1000ma per hour.
However, your charging circuit will determine how much current to actually draw. For example, drawing 800mah for 10 min may raise the temperature to 55 degrees, so after 10 min the charging circuit drops the charging current to 500mah.
Of course, if you're using el cheapo cables, some cables may not be able to support the current draw and you may find that even with 20000000mah power supplies your phone can only draw 100mah.
The SGS2 heats up pretty easily, and it doesn't quite draw beyond 700mah. The circuit built into the phone doesn't allow it to, if i'm not wrong. If your phone is overheating while charging, you better change your case as it's going to cause your phone to overheat sooner or later.
Using a 20000000mah power supply isn't an issue, because the charging circuit within the phone will be able to draw only a certain amount.
Me, I plug my SGS2 into a 2Ah charger every night to charge, and yes it's perfectly fine. I'm only upset that after buying an expensive 2A charger, I realised that the phone is not able to draw high currents (phone even heats up to 55degree Celsius when charging).
Charging the phone on a ice pack (which lowered the phone temperature to 16 degrees while charging) didn't increase the amount of current drawn by the phone, even on a 2A power supply.
My humble advise is, stick with the stock power supply, or at most get a 1A version. No need to splash for a 2A power supply. If you really need faster charging, get a battery charging dock.

yes of course it does. It consumes a certain amount of ma per hour, doesn't it?
Personally, there's a app called watchdog, look for it, IMHO it helps to catch rouge apps better, and manage battery better.
I thought the whole idea of having a universal micro USB charging connection across most good brands was so you could use other chargers!

Well I just like the widget, which shows me also the battery temperture
I hope it doesnt takes too much
I just got my S2 5 days ago. All this time I been wondering why it takes around 5 hours to charge from 20% to 100%. At first, I been using my G2X charger, it was rated at the same 5V 1A output so I thought it wouldn't matter. Then I used the included Samsung charger with same LG cable, no difference. Now when using the Samsung cable, it only takes about 2 hours to charge from around 15% to 100%.
Is this just coincidence? Is my phone too new and just needed a few cycles? I'll test again tomorrow, or when my phone reaches below 20% with the LG cable.
There's been known issues with using chargers other than stock..mine gets stuck at 100% until I reboot if I use any charger other than the OEM that came with it.

From my experience you're going to always want to use the charger and cord that came with the phone. I bought my Galaxy S II off the streets and it did not come with the cord, so originally I tried using my OG Droid charger since it's micro USB too but it wouldn't even accept it at all (I'm pretty sure because it was too under-powered for the Galaxy S II (My speculation)). I tried using an older LG micro USB cable too (I think it was even older though) it didn't work either, so now I use my Vizio TAB micro USB cord which seems to work fine.
But also at my work we have a 3rd party micro usb charger too but it's universal, but if I charge my phone on there, not only does it take longer to charge it doesn't hold the battery as long.
So what I've figured out is you're gonna want to use your own charger the phone came with to achieve maximum battery life, also unplug the charger right away when it hits 100%.

Wow lol I post the same thing every second day on some forum or other xD
The usb is special in the sense it has a nice rubber feel and cool plastic iphone style caps on the end..
Its a MICRO-USB male to USB male cable, nothing more, seeing as it is still a standard USB cable it has a max current of 5v (5.25 I do believe..), plugging it into a USB to AC converter over 5v can screw up the device and cable, sscond point.
Standard charger is 5v AC, using a charger below wont cause harm, but using one above can screw up your phone and battery and not ground it properly..
3rd point, keep in mind the mAh on the charger when charging, some (for like bluetooth headsets) are only 500mAh)
mAh is an acronym for ampere an hour, and in short, for chargers measures the current sent to the device at an hourly rate, for batterys (such as lithium ion) measures the actual charge capacity of the cell, using one with a higher mAh then the stock battery (1850mAh) will only charge it quicker and is recommended.
Fourth and final, remember with USB to AC adapters that some only have +5 and ground enabled (2 outer pins), ising the device its meant for on a ac adapter with all 4 pins enabled will make the device try to establish a connection and can again, make it not ground properly. I think ours has the 4 pins enabled though so ignore the last point..
*edit
Lmfao at above few posts (your theories have no basis, allow me to explain)
When you plug your charger in, regardless if its connected or not, its "live"
That being said, the every cellphone (keyword: cell) uses a lithium-ion battery,
That cell has a control board with a chip with a bit of information, some variable, the device has READ access to this board, and collects informagion such as max mAh, current mAh, and min mAh, the device then calculates from that, a percentage,
It then displays that information to the user, the minimum (displays 0-1%), is usually a value around ~100mAh if the cell dies to 0mAh, this can reset the control board and drasticly reduce the batterys expectancy and overall life.
Also, the actual chip on the phone, is simply for, when the battery is full, (current mAh meets max)
Said device drops connection to the cell and resumes on AC, leaving battery fully charged.
Unless you use a charger outside above said specifications, its literally impossible for a charger or file on said device (referring to batterystats n00bs who dont research) to adjust or recalibrate a lithium ion battery.
Hows that for a response I kept it clean

That's exactly my point. Shouldn't all micro USB cables be the same? I been charging all my other smartphones with many different micro USB cables and they all charged normally. Now with this phone, it takes over 5 hours to charge with my LG branded cable, this is with the stock S2 charger. Now with the Stock S2 cable, it charges in about 2 hours.
I'm gonna have to test again with the LG cable, as others reported long charging times within the first few days.
BTW, the current rating on a charger is NOT the hourly rate (ah). Also charging a lithium ion battery at a rate of 1850mah or higher should not be recommended.

Simply put its an OS, As all OS's they have services that can start at different points, and also open different apps, also using rhe device, applications still in the ram, connection strength will all effect this its impossible to check 2 differenf charge methods accurately enough to get a definitive answer without 2 identical systems, apps, data, kernal and all, one on top of the other, plugged in simultaneously, in sleep mode, to the same outlet :/

I have 3 chargers I use for this and haven't had no issues, there is no way using a different charger (unless its outside above said specifications) that it can do anything to your device including screw with the charge level.. people just don't like to research.
Just an update, it took 2 hours and 25 minutes to charge my S2 from 25% to 75% using my LG cable (same stock S2 charger). I'm gonna test with my Palm micro USB cable next.

Using one equal to or higher then battery capacity IS recommended..

The Faraday constant is the charge on one mole of electrons;
approximately equal to 26.8 ampere-hours. It is used in

value may be used to approximate the integration of power. [3]
In summary, the higher the mAh, the longer the battery will last.

For chargers, the higher mAh sends a larger current of the same voltage to the device, charging it faster, lower mAh can and will cjarge slowly.. I'm not sayin go use a 5v 50k mAh charger for the battery and charge it in a split second here.
Wtc! I hit edit! Mod plz merge these...
Charge rate of 1C = the capacity of the battery, in our case, 1C = 1850mah. It is not recommended to charge over 0.7C when it comes to lithium ion batteries. If a charge rate of 1850ma is recommended, then why do all chargers top out at 1A?
I collect high performance flashlights, most of them use lithium ion cells. I know about charging and discharging li-ion otherwise I could lose my hands.
Anyway, the point of this thread was about the stock USB cable vs other cables. The only thing I can think of at the moment is that my LG cable has more resistance than the Samsung cable, which is why it charges slower. Though that's hard to believe is the charging time is more than double.
doug36: I've seen you post in other threads, all you like to do is insult people, or at least try to. This is the last time I'm gonna post in this thread, you keep posting irrelevant information.

I've noticed that the charger that comes with the S2 has a special hook on one side and looks distinctly different than other usb micro cables.
Personally i think it's really dumb.. wasn't the point of micro Usb to be uniform across all phones?!
Sounds like a good way for Samsung to make some extra bucks.

Well lately my stock samsung charger has been terrible.
Even when I plug it into the wall it charges so slowly that if im below 15%; it will die
When left alone or charging while off for about 45min it will have up about 2-5%; so there's a major problem here.
But using a different charger and it charges at a faster(normal pace); 5% to 65% in appox 1 hour.

One of the immediate side effects will be that your phone will take a longer time to fully charge your battery.
If I helped you out in any way please thank me. Thanks.
Not sure how the blackberry chargers are. I know some of the Motorola chargers are accepted by the phone for high current charging (any charger that doesn't puts the phone in low current mode).
I charge my phone every night on my old 700mah Samsung charger and while it does take longer youd hardly notice unless you were trying to get as much charge in say an hour as possible. So as long as the phone doesn't limit it you should be good. <500mah is very noticeable.
I know it will take longer to charge. But Im not as familiar with appropriate charging output for li-ion as i am for ni-mh Sanyo eneloops for example that ideally should be charged at 220ma to maximize cell life.

The rule still applies the less current used to charge the better the lifespan. The phone was paired with a battery with the intention of using a 1 amp charger. The phone will only allow high current charging mode if it thinks the charger is Samsung. Shorting the data pins is a way to fool it and many aftermarket chargers already do this.
With your phone on and the phone in low current mode (320 mah i believe) you will have a hard time charging the phone if anything is wake locking the phone even screen off. You will even have trouble charging and using the phone at 500mah depending on whats going on.
The phone will be eating some amount of power from the charger, the battery is not always seeing as much current as you might think. I always stick by the practice of not deep discharging it, LiION would rather be topped off then not charged (geeze remember NiCad laptop batteries.... lol). I feel this battery will be the shortest lifespan of any phone or laptop I have ever had. Just due to how much use it sees.

Any micro usb charger should work. I've had a dozen or so different gadgets that all use micro usb from Blue Tooth headsets, to speakers. I use all chargers interchangeably with one noteable exception. My wife's Nook Tablet will only charge using the provided Nook charger. Found that out the hard way.
I have also found that not all micro usb cables will provide data transfer for all phones. I'm guessing different pin-outs? For instance when I was trying to root my ET4G, I forgot my OEM cable at home so I tried to use my EVO cable. That dind't work well at all.
My old blackberry chargers seemed to work fine but I started seeing some strange jumping around of the battery while using. For instance it would all of a sudden jump up to 100% charged then if I unplugged and plugged back in it would go back to 70% or whatever. I went back to only samsung or just charging off usb. I use my pc, printer, cable box etc to charge my phone.
I charge mine with either the stock charger that came with my E4GT, or an old 700MAh charger that came with my old Samsung Rant. Occasionally I use the charger that came with my HTC Evo 4G. I really can never tell a difference. Although, like someone above said, it seems as if non-Samsung usb cables will not charge when plugged into a computer. That's how it is with the HTC cable, and I've also tried an LG usb cable and got the same results.

I had the exclaim, the replacement to the rant and thats where my 700mah charger came from.
All of my other Micro USB cables except the one are non samsung and I use them all for charging, data and they charge while connected to pc. But none of them are from other phone manufacturers or anything. The Micro USB spec is what these phones are using there is no difference.
The difference that matters most of the time is tolerances. Its easy to end up with cables that will work well in one port but not another. The rest of the cable may also be out of spec and not work well or at all for certain purposes.
I've ruined two batteries because of non-OEM chargers on the ET4G. (Actually, ruined two, and made a third battery just render terrible performance.) I definitely don't have the problem with other devices I own, and it's definitely happened with two separate ET4G's I've owned.
So, "be very careful using alternate chargers" is all I would advise.

Please correct me if I'm wrong but isn't electricity the same no matter the source?
If the phone is looking to pull 1A and your charger is rated for .7A I'd be worried about the charger not the battery, which technically is a cell not a battery.
Tolerances were mentioned before and I think that is most of the problem with certain cables working fine for some people and not others. All connectors and cabling are supposed to meet the USB spec and many cheap ones don't. Also the supposed 10,000 insertion rating for micro USB is a bit optimistic imo. I replace cables after a couple months max because of loose connections.

Not really because these chargers are doing AC to DC conversion and voltage regulation is a huge factor in its job. With a bad charger design not only can charging be affected, possibly even hurt the battery. Since the phone will consumer charger power to run while on the charger the phone can become unstable. Not talking a defective charger, just bad and cheap designs.

If the phone is looking to pull 1A and your charger is rated for .7A I'd be worried about the charger not the battery, which technically is a cell not a battery

I think about that alot actually. Coming from PC power supplies you never want to overload the unit. But I know for a fact I have devices that demand more from chargers than can be given, and do not have the low current and high current modes like this phone.
I am no electrical engineer and am only familiar with AC to DC and DC to AC circuits and various voltage regulation techiniques. But it is possible to current limit as well right? You design a half amp charger, with the data pin short to put the Samsung into high current. You limit the current to 500 mah but over build the components just a little to increase lifespan.
Anyways, I bought a 2.1 Amp RCA wall charger from walmart last night on a wim. 9 bucks, might come in handy when i get a tablet. Has a 1 Amp side and a 2.1 Amp thats shared with the 1 Amp. Phone didn't show any ill will to it and I had my Schosche GoBatt on the 1 amp end. If the phones drawing too much current could be bad in the long run but its working so far. Charged at the normal speed of the stock charger.

Not really because these chargers are doing AC to DC conversion and voltage regulation is a huge factor in its job. With a bad charger design not only can charging be affected, possibly even hurt the battery. Since the phone will consumer charger power to run while on the charger the phone can become unstable.

I agree with you on bad and cheap designs. How many tv's and other electronics have been rendered useless by a few substandard capacitors that saved the manufacturer $.02 per unit?
I try not to use any charger that doesn't have HTC, Samsung, etc on the label. I figure if they were willing to back it warranty wise for the original device it should put out clean enough power.
I'm far from being engineer but I do quite a bit of hardware hacking and learned a little bit about electronics when I was at Ft Gordon. So I'm not completely lost around a multimeter
I would imagine that there is some protection built into the charging circuit of the phone itself. How effective or what kind of tolerance Idk suppose I could look for datasheets if anybody really cares.

I mean compare to wall AC charger, that is.
question.................................
no
charging a battery is always very "difficult" for the battery. if you charge not so fast, the battery wont get hot anymore and it's better for battery life. but it takes 2h 30 minutes and with a/c you need 1h
nope..not at all..usb charging gives very less amount of energy compared to AC charging..thats why it takes more time to charge and it is completely safe

True. I prefer charging my phone by USB. This way my phone never gets hot. If your don't have time then use AC charging.

but whatever happens just avoid car charging!! its can do more damage than we can imagine

Becoz car battery does not give stable electricity and output with variance electricity that may damage your battery.

I've got no idea if its safe for the battery, I prefer AC, I never charge my arc over the computer. What about the difference between USB and AC is that AC gives you 850mA an the computer USB(2.0) only 500mA!
Car chargers are safe as long as they are decently made (Fully Regulated). A good regulated Car charger is just as safe as any other charger.
Lithium Batteries are pretty hardy as far as charging goes. (just dont over charge or fully discharge)
as far as USB is concerned, some USB2 ports will supply up to 900ma,
I charge my phone on my Tablet charger all the time (2000ma or 2Amp) simply because it is FAST. sure the phone gets warm but the phone/charger will regulate the charge as it needs to.
it is also good to note that the quality of the charger is very important.
cheep charger = more likely to damage battery as well as cause funny issues with the phone when plugged in.
Pvy.
Exactly. Your battery will prevent it from getting over charged. It's safe.
Personally, I use Nokia chargers as they deliver a higher output.
Nokia AC-10N gives an output of 1,200mA. [Home - AC wall charger with a long cable]
Nokia DC-20 gives an output of 1,000mA. [Car charger with dual USB ports; both ports output 1A each].
Been using both for a long time now without any issues. Didn't go for the SE chargers because of the lower output, which takes longer to charge the phone.
And to the OP, USB charging is safe.

Could you guys recommend me a wall adapter?
I heard that i should get a 1500 mA one, but the best i found on amazon is Belkin Universal USB Wall Charger EU which is a 1000 mA ( i'm not allowed to post links yet, but if you search it it's impossible not to find it). I have to tell you that i can only buy it from the UK and that it needs to be a standard EU plug.
The one amazon.de sent me charges fine, the only issue is that it turns on my device if i try to charge it when it's off. The charger is a 5v 1A.
My iPhone 5S wall charger is also a 5v 1A but it "behaves better" i guess, because when my moto G is off wheni plug it to the iPhone 5S wall charger it doesn't turn on my phone automaticaly, it charges fine and the moto g only shows the battery image on screen.
Both charge ok (1A 5v), but if i want to charge my phone when it's off i guess some chargers won't be able to do that. Maybe it's an voltage accuracy.

I use adapter from my Nexus 7, otput is 5V 2A and no problems.
Any wallcharger will do as long it is 500-1500mA but i think anything over 1500mA can be used, but the device will limit it to 1500mA.
But i wouldn't recommend anything over 1500mA as it could damage the device.
The higher the mA is the faster it will charge.
Currently im using the Sony Ericsson Live Dock DK10 to charge my Moto G but im looking for a more powerful charger.
Press Thanks if i have Helped!

Additional amperage does not harm the device, only incorrect voltage will. The phone will only draw as much amperage as the charging chip allows.
Having said that, keep in mind that quick charging will wear out the battery faster than a slower charge.
I'm using a 750mA, 5V Blackberry charger for mine - from empty it takes about 2hrs 45mins to fully charge, so a higher amperage should be pretty fast. Doesn't boot the phone if the phone is off.
i bought this one
http://www.amazon.com/gp/product/B007ZN5LE0/ref=oh_details_o00_s01_i00?ie=UTF8&psc=1
didn't receive it yet
In case anyone is wondering whether the old Apple wall charger is working or not (the one from circa 2007. I broke my other decent wall adapter...), it's working almost perfectly. It's correctly recognized as wall charger and ~1A is drawn from. That's quite surprising, It had always been wrongly detected by all the phones I tried to charge with it. The only drawback is that the device can't be charged when off, the device will simply boot as soon as it's plugged. This doesn't happen with proper wall chargers (at least on JB, I don't know if something changed with KK).
To know if a wall charger is detected as such, dial *#*#4636#*#* and see if it says "USB" instead of "CA" in the battery informations. Usually USB means lower current (~500mA) and kernel wakelocks (not always this one, it depends on how the charger is detected). That's not good.
You can also get the amount of current flowing though the battery using CurrentWidget (look for it on the Play Store) or reading the files in /sys/class/power_supply/battery/.
nothing happens if the moto g connect a charger that 2.0a galaxy s4
The Asian dual sim version comes with a charger with a hard wired cable, rather than a micro USB cable (and interestingly, its only got 2 wires connected from what I can tell). Its 500mA, and mine uses a UK plug. I've also tried it with a HTC charger (the moto charger has a VERY long, unwieldy cable) thats also 500mA and it works too. There's no real need for a higher amperage, and it does tend to charge pretty fast.

Hi, is it possible to use the Live Dock to connect USB devices on the Moto G?
Thanks in advance!
I am using the adapter of iphone 5s, it's a 1A, is it good or not?
