I just wanna ask if is it just OK to use a SAMSUNG CHAMP DUOS charger on a NOTE? Same with using a NOKIA E72 MICRO USB CABLE for PC CONNECTIVITY on a NOTE? Because when I tried it both are working fine. I am just worried that my NOTE will get damaged. I prefer DUOS' charger because it's longer same with the NOKIA E72 MICRO USB CABLE.
Thanks a lot!
Whatever charger you are make sure it should nor exceed the specification recommended by the manufacturer. For galaxy note we can use 1000 mah 5V rated output of any brand. I think we can go upto 1200 mah but this is completely at your own risk. Beyond this specifications physical damages may occur depending the exceed of limitations.
I am using HTC's charger of same specifications.

I been using Samsung DUOS charger for couple of months. So far ok. Although, I am curious about those charger with 2Amp output. Supposingly charged faster but so sure whether will cause damaged to the Note.
It depends on the type of your charger.
The amperage only says how much electricity the charger is able to produce. If it's a fairly new charger, it'll give only as much as the device connected to it will take - and your phone won't take more than it can handle.
Any charger with usb output and proper voltage will work, unless it's amperage is below the minimum required by the phone.
The KERNEL controls the charging current.
If you are using the stock kernel, the Note only gets max. 1000mA (AC-Charging) independent of the used charger.
Charging with a 1200mA-Charger (used a Nokia) wouldn't change the charging time due to the limitation.
As long as the charger obeys the USB-specifications, you shouldn't hurt your Note no matter of USB or AC.
Regards
battery charging takes three things:
a) a charging source (your USB or car "charger")
b) a charge controller (inside the device)
c) a battery
* A fixed voltage charging source cannot push current into a device, it has a current capability.
* A battery will only accept the current that it desires to charge to its full state.
* The terminal voltage of a battery for full charge is determined by its chemistry.
* Control of charging profile and current limiting is done by a charge controller...
The microUSB connections are rated at 1A max, the charge controller will limit the charge current to this...hence the comment by Thor, and there is no downside to plugging in a charging source that has a 2A capability...just dont assume you are getting 2A out of it

Am Confused..you guys pointing that whatever the amperage is supplied to our device, it consume (charge rate per hour) only what it has been designed?????
If so why am I getting faster charge time when I use my car charger??? My car charger rating is 1250mah..if I employ my car charger my phone gets full charge in less than 2 hrs from single digit battery % left!!! How is this happening??
Upto my knowledge 1 amp of current will take 1hr to charge 1 amp rating battery. Here our device is 2.5amp so it takes 2.5 hrs for full charge by 1amp supplied current. If amperage rating increased duration will be reduced. Normally kernels controls overcharging...but does it controls amperage rating?? I don't think so.

I think you will find that the car charger is not of such as table voltage as the mains supply. Generally car voltages can vary from about 13 Volts to 15 Volts (with the engine running). I am not sure that the car charger regulates this very well (I have seen the same with other devices). If so, it may well be providing more than 5 Volts.
In this case, that is the only way you could possibly damage the battery. I do not believe the Note itself would be damaged. I also do not think it would be noticeable over a short time, but only over a long time.
that is not how charging works...
a) charge acceptance in a battery is non-linear
b) amps*time is not equal to stored charge Ahr.. that would assume 100% efficiency.. and such is not the case. (that would assume zero internal resistance and so a battery would not get even warm if it was 100% efficient at converting incoming charge current to stored charge).
c) your car charger may or may not have a higher current capability than a desk charger.. my samsung charger charges at 750mA max.. my high output charger charges at 925mA max so one charger charges faster than another...
d) If by some lack or variation in calibration you are constantly able to charge at higher currents than the contacts are rated for, expect issues with the microUSB contacts over time..
There is a good reason why every manufacturer specifies and only warrants their devices to be used with their companion chargers.
You certainly dont need to take my word for any of this, the web is there for you to do your own research.

Regarding voltage I checked with a multimeter (a good professional one) it shows around 4.937- 4.982 V. And yes I know that this type of charging would affect battery.. But it's less expensive than the device so I didn't care.

Thanks for re calling my studies at school..now I remember I learnt this year's back..
But still I need further more clarification..
I wonder when I use my device hardly battery doesn't get hot at all.. Only the above portion were the camera rest get hot so is this means efficiency of battery is good and that heat us produced because of processor and other functioning parts? Whereas my older device's battery gets heated when I use heavy. Did I Get right?

My sister got the GT-I9305 a little while back. Usually, she takes quite a few hours to charge it fully, about 7-8 hours. However, recently, it got worse. The phone has been sitting at 37% for over an hour now, and it is still stuck at 37%! I've searched for other threads on this issue but they didn't really solve my issue. It seems really weird that the battery hasn't even turned for the better(or the worse) after over an hour.
Anyone has any insight on this? Thanks a bunch!
P.S. Everything was off except for Power Saving mode and the mobile signal.
use a different charger, cable, port
i own that phone and i have to say that the charger is very weak 1000mAh charger for 2100mAh takes a lot i currently use my nokia's charger it has1200mAh and that makes a huge difference,my friend's uses nokia lumia's or of you have a recent computer you might have a supercharging port that provides much more power,
Hi everbody.
I use 2 different chargers, one from my tablet BQ Maxell Plus, other from another cellular...
NEVER had issues charging my I9300, with stock rom or other one....very fast and until 100%.
NEVER used the original one, but looking at it, is a joke of charger.....
Values: All debitate 5V, and 0.1 and 0.2 Amperes.
You must take in consideration other factors like electronic heat dissipation, filtrate, stabilitie, etc,etc with it seens not works well with the original one....
Who says that bigger ins`t better?:good:
1000mah is more than enough, must be a charger /cable problem

you guys are using capacity units on a charger. Chargers don't have any capacity, they have current, which is measured in amps, not amp/hours. So S3 charger would be a 1000mA or 1A, not 1000mAh
Never had a problem with the original charger. Charge time more than decent

how can that have an effect on the charging current?
On some cyanogenmod 10.1nigthlies versions it has problem with charging takes forever with oem charger, i am now on sentinel rom 4.6 it has same problem. Just use usb port from computer or some media player. It charge to full in maybe 5 hours from usb port, i dont remember excatly.
I agree the S3 Lte does not have the same speed in charging as the 9300 I use to own even though the chargers are the same, even different roms don't solve the issue, need a custom kernel to up the charging current that was available with the i9300 to reduce charging times

Is it just my device or does this thing charge super slow? I can't even get a full charge in a hour and a half and the battery is only 410mah.
Do you use original AC Adapter? I use another one now and I can get it charged in 45 minutes, which is ok to me.

bad battery
I have been having really bad battery on this yesterday left it a home with a full charge at 9.0am and today at 7.30am had 11% it had screen always off and it had not been touched thinking of send it a off to LG to be looked at

I would advise against doing this. You will shorten the battery life due to the extra heat produced. Always use a lower amp charger unless you are in a rush!

Can someone tell me how long the actual charging time exactly takes ?
I use the original charger that comes with the device and it takes about 3 to 4 hours to fully charge the watch.
I find that quite long as I read the comments here.
The first tames it takes only 1,5 hours to charge it but all the other times it goes real slow.
A factory reset didn't help to resolve this issue.
Thanks.
As far as i remember battery have a capacity 410mAh, original charger have power output 700mAh, so charging time should be about 40-45 minutes max.
Change usb cable, if it doesn't help change charger (but it should have power output >700mAh)
PS. AFAIK using charger with power output >700mAh is harmless because watch limits charging current by itself.
Measuring charging time is best indicator.
Charging with 2.0A adapter will not increase the charging speed - the watchregulates the charging current, it will not just blindy "connect" the charger to the battery (in fact, I can't think of any piece of electronics that would have the charging logic in the adapter nowadays).
I had no problems with any chargers, not even with USB charging - the battery is very small, so unless you have a charger that can't put even 500mA you should have no problem.
I've seen an issue where the watch was "charging" constantly and ended with 85% and wouldn't charge anymore - reboot fixed that and it showed 100%.
I was thinking that your charge takes so long because you could have some process draining your battery in the meanwhile (that starts when you connect your phone, like a tasker thing or smt). Newbie thoughts so correct me if this is impossible
I could try to do a factory reset and see after that if it charges much faster then now.
For the moment i have a few apps on the watch, i do not know if it matters or not for to influence the charging time.
It's weird that we do not have the ability to load the watch while it is off.
From the moment that i put it on the charger it turns on automatically !
hello my friends.
the charging dock is limited to 0.85 A (850mA)
It makes not more sense to use a Adapter with 2.0 A Output. It won't charge faster.
Look if every pin on your dock is ok.
also the connection pin on your watch.
Try to clean a little bit with high percentage alcohol.
best regards
Problem solved by using another USB cable.
Now fully charged in 1,5 till 2 hours.
I haven't measured the charging time of my watch but it looks to me pretty fast. I guess with original charger 30 mins - 45 max, not a min more.
Don't sweat the amps

Hi,
that statement isn't particularly correct. The charging system in the watch (as with any LiIon battery) will draw as much current as is "good for it" and no more.
Just because a charger offers 2A doesn't mean that this is the amount of current flowing through the charger / battery!
Hi there, I just wanted to try something...
I see that my Z3C charges very slow with the original UK charger. It charges 800mah every sec9nd. So I tried with the iPad charger and it is still the same.. maybe abit lower, at 600mah. what is going on? it takes almost 3-3.5 ahours to charge this phone... seriouslly? Sometimes I forget to charge it overnight and chargin it at day is like charging though a USB port...

Maths.
2600 mAh battery.
800 mA charger.
2600/800 = 3.25 or 3 hours and 15 minutes.
Today, I don't think this phone can accept anything like 2A charger (don't really know) . Else, it would take 1.3h or 1 hour and 18 minutes.
Get a 2A charger, disconnect every electrical equipment and charge your phone.

But this is strange....If the stock charger says it gives 1.5A, then why is it charging so much slower? at 600 or 800 mah? thats like USB pc speed... Isnt this device supported for quick charge 2.0? I may be able to buy a quick charge capable charger so it charges faster? any solution?

Yes Quickcharging will improve charging time. But as stated above it also depends if you use your phone in the meantime and its idel consumption. The fastest charging time will be if you turn of your phone and then start charging.
I'm getting over 1600mA (according to cooltool), phone charges in 1.5 hours... Factory 1500mA charger, its the same with regular usb and magnetic connector. Rooted 4.4.4

WOW, 1.5 hours, thats just impossible for me. I wonder what is going on... I will check on cooltool
Turn off and charge your phone, and check how fast its charging, mine takes about 1.45hrs with 1.5A factory charger.
Guys I bought a supposed quick charger for my Sony Z3C. When it arrived i read the specs on it and they were 5V 2A. Is it safe to use with my Z3C? If so will it actually make charging quicker?
cheers
It sure is safe (and quick), charge on
so is the stock charger charging at what? it says 1.5A; 800 or as stated 1.5?
I'm getting 5 hrs sot with my nexus 6 almost every time I charge it, but the problem is that it takes almost 3hrs, the charging time was normal i.e. 1.25hrs when I bought the phone and it worked normally for almost 2 months but now for almost a month it's taking 3 hrs to charge, I use turbo charger and my data cable is the original one, if my battery is faulty how can I check it? I don't have any random reboots. My main question is how can I check if my battery is faulty, there's no bulging on the back side
Kennel issue? If you have USB fast charge on try to disable it and see if that works.
I'm running the stock rom, I've tried different custom roms but the issue remains

Sounds more like a faulty turbo charger to me than a device fault. Based on your SOT and physical normalities, I'm definitely leaning towards the charger. Either contact the original place of purchase, or Motorola support and see if you can get a replacement. That way, you'll know for sure.
Yeah I'm from Pakistan and I bought the device from a local retailer, so no Google or Motorola, therefore can't return or exchange the device or charger, as I mentioned in the op, is there anyway I can check if the battery is faulty? In every battery app the battery health is good and in bootloader battery is ok, does every bootloader shows battery ok? Plus in Ampere my battery voltage never exceeds from 4v while charging and battery charge rate is normal

If your battery was faulty, you'd most likely see rapid drain or early shutdowns. I still think your charger is at fault. Considering it's far cheaper to replace a charger, I'd start there first.
It's either the charger or the wire.
If the data pins in the charger don't have a good solder joint on them, fast charge doesn't work. The same goes for the wire. If either of the 2 wires for data inside your charge cable are frayed or broken, again, fast charge won't work.
I suggest starting with the wire. Grab a new one. Make sure it is a wire that can transfer data. There are charging wires that are only good for power that cannot transfer data.

Thanks alot for explaining it like that, if you don't mind can you inbox me your number, I'd like to Whatsapp you to get more knowledge about this, should I get my turbo charger repaired or what?
I don't give out personal information on XDA for my own safety. However, please feel free to PM me and I'd be happy to help.
Curious in any case wouldn't a Samsung 2amp charger be considered as fast as the rapid charger that comes with nexus? After all in all newer high-end charging docks isn't it the amp output that makes it charge faster?
I use my Samsung white 2 amp on all my phones what make a the nexus piece better? ?
