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 lost my USB wall charger and realized my spares don't charge as fast as my previous one...
My previous charger had my phone at +700ma while in sleep, two of my spares can do 400 and one can only do 200!
One time I used a car charger that had me at +900ma in sleep so I would like to try and find a new wall charger that can get me +900.
BTW all the chargers I have used have said they are 5v 1000ma, so clearly I can't just go by the specs they list- I need a first hand experience of a quality charger.
So I open it to the forums. Anyone here have experience of a particularly strong USB wall charger?
I got a good Motorola one on Amazon for pretty cheap and it's been going strong for a while.

Well, you do need one that's 1000mAh.
You just need one from a reliable manufacturer that's not mis-labelled crap.
I'd just look for a quality brand. I got lucky with one for $1.50 on eBay but the seller isn't selling them any more.
Hm so I guess OEM or genuine name brands should reliably be up to their specs, then? Well, I guess I'm going to shop around for one that maybe says 1500ma or more because I believe my phone can take more than a 1A charger can give it, and it probably won't disappoint
Samsung note II have a battery of 3,100mAh, the charger is 2000mA(2A). but my i can use the same charger for my S2. so i guess that the amphere doesn't really matter. just that the higher the amphere of the charger, the faster it charge. But you sure need a higher amphere charger for bigger battery. Hope this help.

I've read that smartphones (at least android phones) have controlled charging circuits that will only allow for as much amperage as they are set to allow. So if you connect a 2000mA charger to the phone but it's limited to 1000mA then it will only draw 1000mA. However as I have noticed just because a charger says it can output 1000mA doesn't mean that it can. I have tried 4 different 1000mA chargers each with pretty different outputs- and if they don't output as much as your phone will take it WILL charge slower. The point of this thread was to gather information on which chargers are reliably fast and ideally economical ones (there's enough OEM chargers I can find for 10x the price of off-brand ones that would hopefully do the job right).
i am thinking about if my E975 is limited when it comes to how many amps it can charge with bcs i recently brought a 2A charger also tried it out on my Google Nexus 7 2013 and i don't feel like it charges that much faster then my original LG charger with a 3meter flat OEM kable.
the charger i brought is said to charge with 2A while the original LG is only 1.2A shouldn't i be feeling a difference?

No, you shouldn't. You can plug it into a 10 Amp charger, but the phone will only draw the amount it needs. Remember, it's not the charger pushing the current to the phone, it's the phone pulling it from the charger. The charging current is determined by the phone - each Li-Ion or Li-Po battery has a controller curcuit. The important thing is for a charger to be able to provide what a device wants to draw - otherwise, it would charge slowly, or not at all. So, a charger should be rated for not less than X Amp. More amp rating won't hurt, but it won't increase the actual current...
oh this is very useful. I also had the same question.
mine came with a 750mA (.75A) charger. As I left my charger at home during the holidays, I had to make due with one that I bought from a nearby tech store. I was very happy with the charger that I bought as it charges my phone really fast. I found out that my new charger was also a 2A model.
so I guess, in my experience, I noticed a big improvement in charging speeds comparing the 750mA with the new 2A charger. But I guess coming from a 1.2A charger, it only makes little difference.
Ordered a QI charger off Amazon (the same Lerway Chinese brand one everyone seems to get) and it's charging incredibly slow. Not sure if the app I'm using to record the charge rate is incorrect or I'm not reading it correctly but it says it's charging at only +200mA max sometimes as slow as <50mA.
Anyone else experience this?

What kind of power source you use to power the charger and what kind of cable do you use?
If you connect the charger to computer USB port it will not provide enough power for the charger. Same with cheap cables, like the ones mostly included with the generic QI chargers. You need a premium USB cable.
Also if you have a thick case on your phone it will diminish the charging current received by a coil in your phone.
Firstly check how much power and what current your charger gets, so instead of plugging the QI charger, plug your phone and check what amperage you get (I use Current Widget). If it's less then 1600mA (maximum amperage that N5 will allow from direct charging through cable) your charger is underpowered and you need to change socket charger to 2A one. If you're using 2A socket charger and still get under 1600mA then your micro USB cable isn't good enough.
Properly and fully powered Qi charger should charge your bare phone (without a case) at about 700-800mA.

Thanks for the info I thought I was going crazy.
No case so that isn't an issue.
I have the phone connected direct to a 3A charger currently and am only getting 995mA charge rate with the screen on and it looks like full 1.5A with the screen off. Maybe a defective QI charger?
Nope. Everything is normal. You just need a better cable that will manage to transfer 2A of current.
QI charger needs 2A input to give 1A output on a coil. Giving about 70-80% efficiency rate, your phone would be getting about 700-800mA.
Since your charger gets only about 1A input it gives about 500mA output. Therefore giving that efficiency rate, your phone should be getting about 350-400mA tops. It is possible that your charger has lower efficiency rate (some have about 50-60%), so the values that you're getting are pretty normal unless you use a premium micro usb cable, preferably with thicker, like AWG24 or lower (the lower value the better) power wires.
Might want to try these cables, a lot of people have had great luck with using them on Qi chargers. Don't know which length you would need, they have 3 and 6 foot cables. For the price, I'm ordering 6 6ft cables.

need a quick help here. i accidentally left my charger at work overnight, and someone decided that its his/her's now ....ive searched around and cant find place to buy the original charger that came with the m8. HTC's website doesnt have it. amazon doesnt. even ebay dont carry it.
i need of a charger. currently using a LG G2 charger thats rated 1.8a 5v .....but with a super slow cable.
is the LG charger okay to use? will it damage my m8 in the long run?
i am also buying this cable on amazon. buy or dont buy?

yes, i know there is a quickcharge 2.0 coming out. seeing as the cable is only $5 ...im thinking it will do for now.
thanks in advance
HTC charger outputs 5V and 1.5A. As long as output voltage is same, you can use different chargers. Ampere value just affects charging time. Higher ampere means faster charge. In long term, it can shorten your battery's life, but I don't think 0.3A can cause an observable affect

I use all sorts of chargers. They are pretty much standard now as far as micro usb goes. As said some are higher rated some are lower. I don't think there is any that will damage the phone as long as its designed for charging and is 5v.
I too use multiple chargers and cables and the only issue I've had is a double length cable that works for charging but won't allow connections to the pc
XDA app on m8 running venom
I charger capable of delivering more current will not damage your phone since the phone won't draw more current than it wants.
