[Q] Can the Note use higher amperage chargers...

... like the charger for the iPad or Galaxy Tab 10.1?
Sent from my GT-N7000 using xda premium

If I use My note Charger for the Galaxy Y it charges the phones much faster, but thats all, no issues. So I presume higher amperage charger should just do well as long as the voltage is not too much.
I am guessing here and would like to see experts' opinion.

I don't claim to be any expert, but using a higher amp charger should be just fine. As long as the voltage is the same as the original charger, amperage doesn't really matter - the phone will still only "suck down" as much amperage as it is designed for. The voltage however needs to be the same, as a higher voltage (or potentially even a lower one) could possibly damage the device. With a higher amp rated charger, you will likely get faster charging times and due to the power specs of the USB standard, no additional risks to the device.
However, like I said I'm no expert...

^ I confirm what the person above said: the voltage matters. As long as it is the same you should be good to go.

BUT: The higher the charge rate the more you reduce the lifetime of the battery. But on the other hand a replacement does'nt cost that much...
PS: The Tab has a 7000mAh battery which can handle high loads easely. No comparison to the "tiny" 2500mAh of the Note...

I use the ipad charger with the note, it is rated at 2 amperes vs the 1 ampere for the note. I also use a blackberry charger at times which is rated at 700 mA and even that works perfectly.

As long as it is standard usb voltage at 5V, it will be fine.
The amperage denotes the MAXIMUM current it can deliver. It does not mean the device will use all of it, unless it requires all 1A, 2A or whatevever the max amperage the charger is rated at.

The kernel controls how much amperage it will use while charging, so you won't get faster charging with a higher amp charger. It will still only suck 1A.

I am not sure that is correct, I think physics controls it. The relationship is fixed, V=IR (Volts = Amps x Ohms). If the voltage is constant, and should be here at 5V, the maximum current will be determined by the resistance of the circuits charging the battery. I believe that has been measured at 1 Amp.
If the maximum current cannot be delivered by the charger (ie it is limited), there is just less current. If the charger can deliver more than one Amp, the circuits will not draw more than one amp, the voltage just will not 'push' any more current.
So the answer is you can pretty much use any amperage charger you like, as long as you make sure it is 5 Volts. More will damage the device and battery, less will not charge the battery.
I am not sure if, as suggested above, a higher amperage charger will shorten the life of the battery, but it sounds quite a reasonable thing to expect. I charge mine overnight with a 500mA charger, and use the stock 1000mA charger at my desk if I need a 'quick boost' before going out.

i doubt this. if your phone is off, do you mean to say the kernel controls the charging rate too? if i use a two amp external charger off phone, how will you argue your kernel theory? so no, kernel has nothing to do with how much juice your charger throws and how much the battery accepts. show me a scientific comparison wherein a tweaked kernel has prolonged the charging time from a 1amp charger by inhibiting flow of current on hardware side.

Just a question regarding charger

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.

Sent from my GT-N7000 using xda premium

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?

I9305 Taking Forever to Charge

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
Sent from my GT-I9305 using Tapatalk 2

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

[Q] Battery drain while connected to car charger

Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon

OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.
Sent from my One using xda premium

Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

Thanks guys. I've ordered a 3.6A charger which had reviews saying it worked well for high power usage Android devices. So hopefully that'll sort things out. I'll post back my results.

OK, tried with the new charger and a good USB cable, and all is well. Even with GPS and Spotify running together the phone still charges slowly.

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.

[Q] does higher mAh harm the battery?

the attached charger with z1 is a 1500mAh charger and i bought a 2100mAh charger which charges faster for sure.I wanna know does this harm the battery?i mean if it was ok why the sony didnt attached a 2100mAh or higher with its flagship!?

mAh tell you about the capacity of the battery. You can even use 1 million mAh.
..and no it won't harm the phone

It does reduce the battery life. Or at least have a little impact on it.

Battery life has nothing to to with the capacity of the portable battery? What are you talking about.
Every charging reduces the battery life. That's why it is recommended to only charge the phone when it is at 10-20% and try to charge it to full.

no it won't
it will just charge your phone slightly faster,
if there's more than 2000 input then the phone will put a limit on it. so it should be fine

The discharge rate.
I might be wrong though cause I didn't read properly.
But voltage does have some impact.

Well the phone is designed that way, i mean sony engineers should be smarter than us so i assume its a best option.
When i use 2.0A galaxy note3 charger on my z1 it takes about 1500-1700mah but no more than 1700.

I use a 12000mAh portable charger from New Trent and my phone battery is in perfect shape. It does not harm it in any way. I don't understand where the confusion is coming from.

mAh is a capacity measure , the bigger the capacity the more times you can charge the phone on a single charge (and usually also the bigger and more expensive the battery)
It's the Amperes which are Voltage/ sec given to your phone that you should worry about. Pretty much all portable chargers are suited to mobile phones and should not cause any harm.

I thought you were talking about travel adapter charger..
Yes current provided and voltage matters.
Silly me I was confused between mah and Amperes..
Thanks man!
But I think he's refering to amperes. Cause the one provided with z1 is 1.5 amp. And the portable battery is 5 ah. So he bought a 2.1 ampere charger.

There seem to be quite alot of confusion here. I am sure you mean the output of the charger, but if you mean the capacity of a portable charger, then it doesn't matter if it is 1000mAh or 1000,000mAh. But if you mean the output of the charger, then we don't really have a clear answer as this was asked few times in the forum, but I will try to explain the conclusion we came to.
our phone is supposed to support quick charge 2.0 which means in theory, we can use chargers with ~4.0 A (if I remembered correctly). why sony used 1.5 A is not clear, but I don't think using 2.0 A would have any effect except slightly faster charging time. I have been using my SGS4 charger (with 2.0 A output) since I got my Z1 (since release date). Last time I looked for even more powerful chargers ~3 months ago, I found that chargers with 4.0 A output has not been released yet and will be released early 2014. When they are released, i will contact sony and see if I can use it with my Z1 as in theory this should mean half charging time. I hope this helps

it won't harm the battery

The higher mAh rating might not have a direct affect on your phone... But what you said that the battery charges faster is a cause of concern. Do check the output of the charger you got with the battery. If the current rating is higher than your stock charger then maybe you're phone circuits may have problems.

Maybe it won't affect at all since the charge current rate is set by the battery chip, not by the charger. What the charger label says is the max output current, not necessarily the actual rate.

Higher current may hurt abit, higher voltage hurts more

Been using the blackberry rapid charger but not overcharging the phone and its been fine, been using it for years. FYI, chargers are measured in volts and amps. The bb one is 2amp and 5 volts.

You cannot judge or decide anything, except you know what electronic part used by that phone which have specific normal rating and resist maximum ampere. So, everything you do with your charger is Gambling!! But, I suggest not too much the different
