Hey guys wanted to know where I can find a rapid battery charger. I'm currently using Anker Battery Expert but it takes around 5 or more hours to fully charge a battery. Would love to find a charger that could charge my battery within an hour!!!

You can get a 2amp charger but the kernel must support fast charging.
Even then i dont think full charge within an hour is possible.
Thanks for the respond.... But not to use with the phone only for the battery. I have a seperate charger for the extra battery but it feels like it takes forever. I do rate it over the phone charger though because if I fully charge the battery with my phone and I take it out and place it on the external charger it shows that It still have around 10 to 15min left to complete charging... I beleive it's correct because it seems to last longet than charging with the phone!!!!

Not trying to revive this post, but noticed people are looking for a fast charger. I have a Touchpad and use the charger to charge my Note. It charges much faster than the OEM.
It is a 2+amp charger. It says 2amp on the label. I tried to charge my Touchpad on a Ipad charger (also 2amps) and the Touchpad said gave a warning saying it will take longer to charge. So I assume the Touchpad charger is 2.5amp. (max allowed for FCC)
Long story short, its on sale for only $4.99. Go get it!

Both the AC wall wart that comes with the Note (I assume that's what you mean by "the OEM") and the HP TouchPad AC charger will charge the Note at 1 A. One is not faster than the other.

No, this is because the iPad charger is wired up to supply 2 A only via the proprietary iPad connector. If you connect it to a micro USB device (like the Touchpad or the Note), you will not get 2 A. You will probably only get 0.5 A, which is the USB standard. That causes the TP to display the warning you saw.
Thanks guys but I still didn't get the answer I was looking for. I'm looking for a universal wall charger that could charge batteries by itself but at a faster pace!!

No. The Note (and most current Samsung hardware) is limited at just over 1A. I'm using a 3A charger with a change-only cable and my Note can only charge at ~1.1A according to CurrentWidget. Without charge-only cable it's half an amp at best.

Hrm I'll have to test this. I have a prime and it's wall charger is rated at 2A,might charge the phone faster.

Well Charging seemed very quick but the CurrentWidget showed charging from 1A to 8A. Listed on their Google play page they say that Samsung probably isn't supported.
The electric current reading doesn't work on all devices. The reason is that the manufactures (mostly Motorola and Samsung) don't support this in the battery driver or in the hardware.

OP, I did some amazoning (new phrase, you like?) and here are a couple options I've found:
OEM Sammy charger: Dunno the charging speeds, but probably 1.1A like the chargers that come with our phones.
http://www.amazon.com/Samsung-Battery-Charger-2500mAh-Included/dp/B0076Z3FSQ/
Also there's this charger/dock:
It uses a 1A wall wart and here's the catch it's mentioned it charges both the phone and battery at the same time so it would split the power, I don't know if it'll shuffle the power around when only one battery needs a charge.
http://www.amazon.com/Hyperion-Samsung-Compatible-international-Packaging/dp/B006QBKTCG/
Long story short, the best you're probably going to get is a 1A charger, most aftermarket units I've seen are charging between 300mha to 400mha.

I've never got off-the-wall amperage #'s like that on my OG Note. I know it's accurate because the Samsung OEM wall charger is 1amp and my phone shows 1100~mA when plugged in. It shows the same #'s when plugged in to my 3amp car charger with charge-only cable.

not sure if this is good for the battery to leave it plugged into the charger when it's at 100%..
i been told before that these new devices it's ok to leave it plugged in...but i don't have a good feeling about this lol
it'd be great if someone can please chime in on this.
thanks all!
Yes it is OK. The charging circuitry will switch to a trickle charger when battery is almost fully charged.

the charging system is getting more and more intelligent...no reason to worry about that anymore
Just keep your batteries with more than 20-30% charge as much as possible.
Sent from my GT-I9300 using xda app-developers app
I leave my phone charged to 100% almost all the time:
- when I am at work I leave it plugged to the USB port
- when I am working at home, the phone is connected to the USB port
- when I am driving the phone is connected to the vehicular charger
- when I go to bed, if the phone is below 70%, I leave it plugged on the wall charger overnight.
Yet, when I am on long bike rides and the 3G+ data + GPS + synch are enabled, I still get excellent battery times.
Over charging any battery isn't very good for it, it's the same with laptops and well pretty much anything, so long as power is coming in the battery will take it, even if it is at a slower rate.
Ideally you would want it to charge to 100% and then a little bit more, maybe 20 mins, to make sure.
However i know we don't live in an ideal world and charging it overnight is the only thing that can be done by most users.
In my work we have a lot of phones plugged in all the time (all brands) and they have some strange effects happening, eg: Unresponsive touchscreen (removing the charger solves this), Poor battery life, glitchy screen etc.
Saying that, all of our phones are plugged in all of the time so it is an extreme situation.
If your worried about it then get a timed plug so it only charges for a few hours and then cuts off.
But you should be fine otherwise.
Just feel the charger when the phone's at 100% and it's giving off a f**k load of heat because the phone isn't actually taking anymore charge and the charger turns the reduced MAH it draws into heat in the charger, so just don't worry about it because the phone does all the work for you and can't go over a full charge.
My phone stops charging at 100%.

Yeah you can use any Micro USB cable or charger as long as it outputs no more than 1000mah.
I thought a higher output was "good" in that it reduces the charging time.
Could you please explain why one must take into account a limit?
Conversely, is a low output harmful: how about charging from a laptop USB port?
Also, I have a HTC One X. Can I use the Samsung charger with it: how do I find out the output limit for the One X?

A higher current can damage the battery and possibly the phone and some people say the phone at any current above 1500mah but still haven't seen any proof yet, and you can probably get away with 1300mah but the more you the the hotter the battery gets then slowly expands and might pop, and yes you can use the HTC charger no problem but check any charger you use for output current wrote on charger, and also yes you can charge from a laptop or any really slow charger you like.

Correct me if I am wrong, but I thought the Samsung phones block excessive current and can accept up to 1amp. Also when using any charger that doesn't have the middle cables short-circuited would produce 500milliamps regardless of charger's output(this can be turned off with custom kernel). That's why there is a list of car chargers on gsII or Note forums that have the pins shorted. That said, people had reported that using HP touchpad cuts down in charging time while increasing heat.
I am looking into this a little more and some useful info I found.
My GT-I9300 charger outputs 1000mA @ 5V. The phone charges up quickly. No problem there.
When using a USB port on my Macbook Air (2012 model), under About This Mac > More Info... > System Report... > Hardware > USB > bottom USB High-Speed Bus Hub listed: I see that 500mA are avail from the USB 2.0 port (conforming with USB 2.0 standard specs), but the GT-I9300 is only requesting/ drawing 96mA, whether I am using the original Samsung USB cable which came with the phone or my favorite short Jawbone ERA USB to microUSB shorter cable.

It just takes much longer to charge.
My One X (S720E) draws the full 500mA avail from the port:
It should be noted that some Apple peripherals/ devices (iPhone, iPad etc.) can request and get an additional 500mA from the port on computers/ monitors that supports this.
Here is the Apple Support Article that covers this.
Pretty much everything uses Lithium-Ion these days, and it's perfectly safe to leave overnight, heck I even upped the AC charge voltage to a straight-up 1200 on AC power.
Charging at lower powers is equally harmless, but if you use the phone you may drain faster than it can charge.
All in all, thse rumors about decreasing battery life are getting sillier and sillier these days. Earlier batteries were a bit finicky, but they have improved A LOT, and honestly, a new samsung battery costs 25 dollars? If I'm still using this device in 3-4 years when the battery finally gives out I'll be very surprised.

You will be sruprised if you use a current monitor. I only have used "Current Widget". You will be surprised how many chargers and cables charge below 1/2 amp while others charge at almost an amp. You can test all of your chargers and cables this way. For example I have a wall charger with a long cable, with what looks like very small wires, suggesting a low charge, but it actually charges at 1000 ma, much better than some really short cables i have. Also apparently if the data signal is shorted in the cable or in the charger it will tell the phone to charge near an amp.
I also have a charger in my car that has a usb connection that says 1a and 2.1a. The 1 amp charges at almost 1 amp while the 2.1a charges at a 1/2 amp. If you dont use the amp app to see this you would never know and be charging your phone at the slower rate
Just for clarification 1a(amp) = 1000 ma(milliamp), 1/2a = 500 ma

I have this http://www.siig.com/3-1a-dual-usb-car-charger.html and it doesnt charge my Note 3 at all. It just keeps it at the same charge, and shows up as USB under battery settings when plugged in
Then I bought this http://www.amazon.com/Kensington-Po...05&sr=8-4&keywords=kensington+4.2+car+charger and for some reason one port shows up as AC charging and the other as USB. Its supposed to be two identical 2.1 amp ports, so why that is happening is beyond me.
Can someone please recommend an app that works well withe the Note 3 to measure current?
Can someone please recommend something that will actually work? I basically want a charger (for car) that can charge my Note3 and my wife's, at the same time, at least at the same speed my OEM charger that came with the phone does.
Does what cable I use make a difference at all?
Thank you for your time
I don't have the GN3, but a GN2. I have and use Ventev 4.2A rapid car charger. You may want to try it. It works well with my GN2. What's nice about it, both ports are 2.1A 5V. I was hoping it would charge my GN2 and ASUS Infinity Pad tablet at the same time, but the tablet needed 15V. Thus, it's end up being trickle charger for the tablet, but does slow down the battery drain.
And it's pretty cheap. Seems solidly build. I also have the wall charger unit and works well too. It may just do the trick.

I'm still a bit annoyed with many andriod 10" tablets needing 15V to charge. I have car cigarette power inverter with a AC plug outlet and two USB ports (2.1 and 1.0) that I can use that will charge my tablet quickly.

Galaxy Charging Current Lite
There's also a Pro version for $0.99 as well. I use the free version and it works just fine, but there are ads, but that's expected from a "Lite" version of an app.
Thank you for the app recommendation. It has been helping. So here are some results.:
Using Kensington adapter, I get 350mah on both USB ports using a regular micro USB 2.0 cheapo cable I picked up at Frys for 2 bucks. Using another cheapo cable but this time 3.0, I get 1200 mah in one port and 450 in another.
Any ideas?

Try using OEM cables or at least high quality 3rd party cables. I ran into an issue with note 2 where my third party cables only charged at 250mah. When I got a replacement it jumped up drastically. Also car will be different than house wall outlet. Compare both.

I had the same problem at first. Then looking at others forums and checking out my own phone I realized that the phone only charges at 1200mah while the screen is on no matter what chargers or cables you use. When the screen is off then is charges at 1800mah like normal. Samsung built this into the phone and I have no idea why.. I have noticed that the Y-CHARGE 4.2 Dual USB Car Charger charges two devices at 2.1amps each. I've tested both ports and they are good. http://www.tylt.com/y-charge-4-2/ Thats the link. Check it out. Hope it helps.

When I had my issues I ended up averaging 1800 mAH on an oem. I used the Galaxy Charging Lite app as well. (Edit: just realizedthat's what you used too)
Just in case, you may wanna try another app. Usually the apps just measure the input based on what software tells them so there is a bit of inaccuracy but not enough to be way wrong. Truest test is an amperage meter or something like that. But 1800 on Wall adapter sounds right bad on a micro usb (2.0), I haven't tested usb 3.0 but it should be higher I would think.

I had the same problem at first. Then looking at others forums and checking out my own phone I realized that the phone only charges at 1200mah while the screen is on no matter what chargers or cables you use. When the screen is off then is charges at 1800mah like normal. Samsung built this into the phone and I have no idea why.. I have noticed that the Y-CHARGE 4.2 Dual USB Car Charger charges two devices at 2.1amps each. I've tested both ports and they are good. http://www.tylt.com/y-charge-4-2/ Thats the link. Check it out. Hope it helps.

Just to be sure, you tested both ports using a note 3 and you actually got 2100mah readings in the app?

This is my limited understanding that comes from researching this myself....
USB has 4 pins that our phones care about. The 5v+, 5V-, Data + and Data -. The 5V pins charge the phone. The Data pins tell the phone what rate to charge at. I believe it is specifically the voltage the phone senses on the data pins. There are some DIY mods out there to use resisters to change this and force a higher or lower charge rate. Those mods were a bit out of my comfort zone so I just skimmed them.
Also, Apple and Android do this differently in some way and most high voltage chargers have iphone and android specific ports because of this (whether they are labeled or not). The Anker car charger I got does this. I don't know of a reliable high amp car charger that has two "android" specific ports. I have tested the Android specific port and it seems to charge at the same rate as the wall charger that came with the phone. I will try and make time to test the "iphone" specific port on my Anker charger to see what mah I get and if there really is an appreciable difference.

If it is not too much trouble, can you download the galaxy current lite app and tell me how many mah you are getting in your house charger and how many mah you are getting in your Anker Android port? Also, I'm assuming you got a Note 3?

The app will tell you 1200 if your screen is on - after is been plugged in, make sure your screen is turned off, then quickly pull up the app after you turn your screen on and it will show 1800

Here's what I've been using. Great so far. http://www.amazon.com/dp/B00GANTT94/ref=cm_sw_r_udp_awd_HsY3sb034XV0R
I bought a dual outlet 4.2amp charger at big lots (got 4 of them actually on sale $10 a pop) that is 2.1 amps per outlet. I use samsung cables with it and my note 3 charges are full speed no problem.
I would just bypass all this and get an inverter for the car and run the OEM charger... takes out all the guesswork and charges exactly the way you are expecting.
Example... turns your cars 12vDC into 120vAC

From my experience with Sony's charging dock on the Tablet Z, I found that it charged quite slowly as compared to a usb connected charge. I would see an overnight charge which is roughly 8 hours to only charge 30% to 85% whereas a direct usb charge would give a full charge within an hour and a half. Just wondering cause I've ordered the Z2 and hoped that the dock wouldn't be such a bad experience cause I don't want to bother with the flaps unless I have to.
I picked up a generic dock from Amazon. Seems to be 'straight through' connections, so chargers as fast as the charger will allow...

The magnetic charging port is definitely slower but mine still charges in a few hours on the dock next to my bed(not sure how many amps the wall adapter is). In my car it seems about the same off the 2 amp charger(so I assume the other is only 1-1.5 amp) with much heavier drain(bright screen, BT streaming, navigation, etc.).

A lot will depend on the quality of the cable as well. I have the no name dock from amazon and it is slow to charge with the supplied short cable but very quick with the Sony one
Sent from my D6503 using Tapatalk
It depends on the charger and the cable, to charge a 3200 MAH battery for the z2
a minimum 2 amp charger and 38 pin cable is definitely a must !
My magnetic charging port charges at a rate of 1% every 1 1/2 mins, 2 1/2 hours for full charge according to my battery stats which seem about right.

Thanks for all the replies guys, I just can't wait to get the phone. I've been on the fence with it for some time now between the Z2 and the S5 (now the S5 Active that just came out). I just wanted a change and the two devices kinda broke even with specs and reviews for me. :highfive:
anyone yet been that crazy to use a 3A charger? Snapdragon S801 should be capable of that.

I did the same, but it takes all night to get 80% whereas the direct USB takes a couple of hours to 100%
Now after i got the dock (cheap one from Ebay) i do have the same Problem!
Takes 7hours to charge from 0% to 75%
using Stock rom + Doomkernel v9
Ookay... I just connected the Mulitmeter between smartphone and dock (it's a hassle.... Hacked USB cable would be nice....)
The official Sony wallcharger (1.5A) is charging the dock and Smartphone with 800-850mA.
I tried Doomkernels Fastcharge and forced constant AC =roughly 1300mA.
Strangly when I set it to 1500 or 2000 in Faux app it falls back to 800mA.
The battery was 85% charged when I made those tests.

I thought fastcharge applied only to micro usb port
Yesterday I got a non original docking station from Amazon.de (€9,40 + delivery costs) - from 42% to 95% chargin time was 1h55min.
please visit this thread:
http://forum.xda-developers.com/showthread.php?t=2789564
Yeah,,,, so.... i made a reallife test!
Set FauxApp to "Constant AC" in FastCharge options.
in 5 hours it charged 16% xD 3.2% Per hour.
Then after that i set to "Custom" 1200mA
Charged from 76% to 100% in 3.5hours
tonight i'm trying to empty the phone (Unreal Epic Citadel might be a good idea, or maybe GFXbenchmark Battery Test....) and set to Custom 1500mAh and see what happens.

So.... anyone has one of those QuickCharge 2.0 Adapters Mentioned here ?
https://www.qualcomm.com/products/snapdragon/quick-charge
i wonder if it would charge faster than the Sony 1.5A charger.
edit:
Phew... dem chargers! 18W and 30W editions!
5V 4A
9V 2.2A
12V 2.5A
20V 1A
Quick charge 2.0 does only use 9V sporadically doesn't it ?
Edit2: and 9V 4A .... wow
I wish. I could do charging in 90 minutes. It takes twice as that now.
Charger that comes with this phone is just labeled fast charge... Phone seems to charge pretty slow also from what I see.
i just installed some dual 2.4A usb outlets in my house they charge very fast from 8% to 100% in about an hour, considering the Amperage on the stock charger is 1.8A it doesn't seem like it would be enough to use the phone while charging.
I havent used the stock charger yet but mine reads it puts out [email protected] 1.8amps or [email protected] 1.8amps. I am waiting for my battery to get really low so i can see how fast it will charge.

When the OEM charger is plugged in, swipe down and you can see it says it's being fast charged.
When plugged in, my screen does say Quick Charge, and my phone charged rather fast, but still getting used to it. Even when I had my phone plugged into a normal new USB C plugged directly into my usb outlet, it seemed to charge much faster than I was expecting.
Yes I understand it says fast charging, so does the quick charge 2.0 with this phone, but is it actually charging at QC 3.0 speeds??
It seems silly they would make a Quick Charge 3.0 phone and not supply the relevant charger.
I ordered an aftermarket QC 3.0 charger, I guess I can do some comparisons when it shows up.
Anker makes a very nice Quick Charge 3.0 charger.

I performed a test with the aftermarket QC 3.0 charger linked above and the one supplied with the phone. I drained to 90% and as soon as it hit 90 I plugged it in and started the timer. The results are nearly identical in how fast 100% charge was achieved.
The first screenshot of total time was the aftermarket charger and the 2nd is the factory charger. I would venture to guess based on these results, the factory charger is QC 3.0, but you can draw your own conclusions.

Well if the stock charger says 9V @ 1.8A and 5V @ 1.8A, then it's not true QC 3.0 as that uses voltages from 5V - 20V.

There only will be a minimal effect because the original charger has a 9V and 1.8A = 16W rating.
All Aftermarket charger with QC 3.0 had a maximum reading of 18W, 9V at 2A or 12v at 1.5A.
And you can't do a comparison at the last 10%percent of the charging process, because of of the method that's just to charge lithium battery's.
Lithium-ion battery see charge and discharge
Around the last 10% will be constant voltage where the charger has minimal influence. Because the internal resistance of the battery cause the amount of power that goes in the battery.
Ca you do another test with larger charge?
Before any of you rush out and buy a cheap charger to save a few bucks I'd think twice about it. I have been screwed by cheap chargers on more than one occasion which is why I refuse to buy them anymore.
I've had them stop working after a couple weeks and many of them made a very annoying noise. Some made a high pitch squealing noise while just sitting there doing nothing and others made the noise while charging.
Slow and Fast
I noticed it charged VERY slow at first while i was using the phone at the same time. I notoced the charger wasnt even slighty warm to the touch after 30+ minutes. That made me think and noticed if I left the phone at rest without turning it on it charges much quicker and the charger got warm quick. And the charger actually cools down if you start using it half way through a charge.
*I took a screen shot of the battery usage graph, but I'm new so I can't post photos yet so you'll have to trust me lol
My rough estimates are that if you are using the phone while charging it will take just over 2 hours, but if you don't touch it then it charges in under 50 minutes.
Mind you phones battery temperature also effects the charge rate, is if you have it on top of a pillow it might not charge as quick.
You don't wanna use the phone while it quick charges. Turn screen off for an hour and it will be done

Dude how are you basing charging speeds from 90% to 100%.../
The charger that came with the G5 is the same charger that came with my v10, it is only Quick Charge 2.0, I have compared the model #'s and they are exactly the same. I have gone on amazon and ordered a Anker Quick Charge 3.0 plug and a couple of their USB-C cables.

I just contacted LG through their website via E-Mail regarding the Quick Charge 3.0 charger, I will follow-up once I receive an email back from them. The website advised that I should receive an email within 24 hours.

It's a wonder why anyone tries to share information on this site with comments like this. Since you probably only skimmed over what I posted, I said feel free to draw your own conclusions and that it was a 'quick test'.
When the phone gets to 80 % the other 20% go pretty slow, might even be similar to the QC 2.0... But 50% to 100% would be a good test, and we can see if there's a difference
