So, I don't know if this is just my device or maybe already known. I don't see it here(or google) so I am going to post this so others can find this info faster than the 2hrs it took me.
Some Li-Ion batteries have a low max charge rate. Meaning you cant "over-current"(mA "Milli-Amps" or A "Amps") them too much(saves life). Well my Razr just showed me this. This can allow you to charge the battery faster if you have one that is tolerant of the "over-current".
Apparently maximum for the Droid RAZR is somewhere between 850mA and 1000mA
Tried using an HTC @ 1A and no joy.. wont charge.. actually says charging.. but the battery seems to have flipped the switch to not charge; and just continues to discharge normally; even the hidden status(dial *#*#4636#*#*) says charging but obviously not! Tried different HTC models and different cables. I am now only using my Moto supplied cable.
Even after it was dead. It would show the charging screen @ 0% and the light would be red. Stating that you cant turn it on cause there is not enough juice to finish boot. It would never go Green no matter how long I waited(10-15 minutes) usually only takes 5 minutes.
Found my OG Droid charger; remembering that it was lower than 1A. It actually is 5v 850mA. Charging away!
Remember the stock charger is rate @ 5v 750mA - this means you can probably use chargers from 700ish to maybe 900ish mA. I cannot confirm these estimates. Anyone else seen any other rates work?
Hope this helps someone down the road. I know it would have helped me!
MODS - Please, if this is wrong info please DO NOT HESITATE to notify me/remove/edit my post. I just want the right info somewhere, cause it was not well documented anywhere i searched via google.
Also - Thinking more on the subject - this could be the "Authorized Charger" bull that Moto likes to put on its devices i.e. The RAZR flip-phone was notoriuosly bad about this. Even my old nextel "beep beep" had this problem with OEM chargers. Had to spend $15+ on the official one. Again - if this info is wrong in ANY way please fix it or remove it.
use official 850mA charger and be happy. Motorola also confirmed using 1A chargers without any problems but any ways original ones are recommended.
Brilliant, my problem now makes sense!
Couple of questions: What does this mean to charging via USB instead of mains? Is it the plug or the cable that is rated to a certain ampage?
One more question. I found another usb plug rated to 300mA. I presume using this will just mean the phone charges slower? It won't have any negative effect on the battery?

Just adding my experience... Have been using an iphone wall charger w/ the usb jack on it and the supplied motorola cable. Its listed as 1000Mah. Battery Monitor Widget shows it charging around 945Mah. Doesn't get hot, charges like a bat out of hell. Down side is phone is about 60% unresponsive during the charge.
Found a little info on this. Apparently different cables, when plugged in, short different contacts to let the device know what it's plugged in to. Resistors change the current. Audio out can tell if it's plugged into a dock versus USB versus wall charger. The Verizon replacement didn't work for me, but an hard incredible one did. They both charged but only the htc recognized computer connections

My stock Razr wall charger is 750mA. I use a 1000mA car charger and it works fine - doesn't get hot and charges faster.
But sometimes you do have to be careful. I had a friend who's noob mother fried her Bionic with a charger that was too many mA for it to handle.

strange... my stock charger's rated 850mA.. maybe because i use international GSM version of RAZR.. but it charge just fine..
but even i tried charge it with blackberry's 700 mA charger or my ipod touch 1000mA charger it both charge just fine.. and it feels like the 1000mA charge slightly faster..
too bad i broke my old nokia n900 1200 mA charger..
I'm using an HTC 1A charger: the RAZR doesn't become hot while charging and it's charging faster.
The limit is 1A anyway.

dang! so i guess nokia 1200mA charger won't be any good then..
thanks for the info though.. i was thinking of getting myself a nokia charger after read this thread..
Ever since my first motorola I've noticed that the stock charger is 5.1 volts.
Charging with other brands always seem to give worse battery life.
My old Rizr only lasted a day when charged from the USB of my computer, but 6-7 days with the original part.
Some of that is apparent with my car charger too, it says it's taking charge, but sometimes it will run backwards with GPS running..
I experience the charger issue last night.
I had low battery when I went to sleep, put the cable in and it said charging.
Came late to work because the phone drained the battery instead of charging. I used a 5V 1.2A charger and its been working great until last night. And I noticed my original charger is 5.1V 850mA for the Razr.
You learn something new every day!

Does anybody else have an issue with their X2 when it's plugged in to either the wall or computer of the screen not responding like normal thus rendering the phone completely useless while charging? It doesn't happen every time, but probably 35% of the time which is still more than it should. And it's not just my phone either, my wife's X2 does it as well and all 3 of the X2's I've had have done it on both stock and eclipse.
Just wondering if anyone else has ran into this issue.
Tapped from my Eclipsed X2
I believe the charger is to blame not comlatible. Not every charger is setup with same pins or wattage... if ur mis-matching equipment.

I have five different USB cables and they all work fine. I've never seen this issue before. Weird!
Sometimes mine does this not sure what causes it. Seems like phone is usually warm when it does. maybe it gets too warm with screen and charging at same time. i have had it happen with every ROM even stock.

I've used my old Crackberry charger along with my usb cord for the cpu, car and wall chargers. Havent had this problem. Strange......
Today it hasn't happened on the same cable at work.
Mine doesn't seem to take issue with any specific charger or cable except for one which is the one that was sent with my wife's phone from verizon, screws both of them up, and it's a moto charger with the same voltage/amperage as the other moto ones, but it has a 9 ft cable.
Tapped from my Eclipsed X2
Interesting it has happened on vz provided chargers. Do theyhave the Moto M on them, or sonething else?
Mine specifically is 5.1V~850mA. Has a USB cable. Has a port we can plug a cable into.
I'd be curious what everyone else has. I wouldn't think it's the cable itself but working in technology, I've seen stranger things.

It could be one of two things, either:
1. you're using a usb cable with a broken data pin.
2. you're using a charger that doesn't output enough current.
the problem lies in a lack of available current in a certain charging state, a "fast charge" if you will. you get either not a high enough sustained supply voltage, or "dirty" power (essentially a little AC in your DC) and that really screws with the capacative touchscreen.
with a bad cable, the phone thinks it's plugged into a charger and not a usb port so it will try to draw up to 850ma from a port that can only feed 500ma if you're lucky.
with a bad charger, or one incapable of supplying the required current, you get "DC ripple" where your voltage fluctuates up to half a volt or more, 60 times every second. generally your phone will get very warm under this condition as well.
so it could be a cable, a charger or a combination of both.
some car chargers are notorious for making dirty power... so are some cars...

Oddly enough I have zero problems with the car chargers, the phones work fine when plugged into them.
Yeah the newest cable is one that is USB and 9 ft long but not moto one that verizon sent with my wife's phone. The moto one that came with mine an the two moto ones I got from Amazon I don't have any issue with but the cables are so stinking short they are a pita to use anyway (2' cables).
I've also noticed that the USB ports on different computers charge at different rates as well. My work computer will barely charge the phone and sometimes can't even maintain the battery level if I'm using it. My laptop at home charges it pretty good but you can't use the phone because you get the screen issue again.
Tapped from my Eclipsed X2
Yeah, I have had this same issue for quite some time and after reading this forum tonight I tried a new charger and BAM, problem fixed! I had thought it was my phone, but it was definitely the charger. The one I was using was the Verizon 9ft charger they send out with replacement phones. Model: B141000. Black with green on the back. Gave my wife my charger that came with the DX2 to take to work and use because I liked this big long cord. So for months now whenever I tried to use the phone while it was charging it lagged so bad I would have to continuously unplug it and plug it back in when I was finished. Needless to say, having a text conversation when battery was almost dead was really annoying...
So when I read this post tonight I went up and grabbed my old Samsung charger from my old Samsung Fascinate and sure enough it worked just fine... No lag what so ever. So I am guessing it is an issue with the DX2 and the generic Verizon charger they send with replacement phones not being compatible...
Furthermore just as a test I just tried the actual 9ft USB cord with the Samsung plug you plug into the outlet and its still working fine... So I assume its the Verizon plug part not putting put enough voltage or something. Pretty happy that I can seemingly still use my 9ft cord! So if you have a spare plug I would say give it a try!
I just posted this in my other thread Information on charging the note, but that thread is really lengthy and I thought this was worth mentioning in its own thread for anyone who might be looking for a good car charger, but doesn't want to read 8 pages of other information.
I had been looking for good one, and started with the motorola charger that I've seen recommended a few times. It's cheap, nicely made, and does have the data pins shorted, but for me, it didn't meet my needs because when using GPS in the car. With the screen on, the phone actually discharged and did not charge. It discharged at about 6% per hour. This is not surprising because when measured, it does not put out the max current that the note can accept (it puts out about 850mA of charging current via my measurements).This charger, on the other hand, puts out the max charging current your note can take (1000mA). I have verified this. When using GPS with the screen on, on my note at least, it actually charges the phone at a rate of ~3%/hour instead of discharging. It will even charge the phone if you are using GPS + screen on + also streaming music (ie pandora). That 150mA difference may not seem like much, but for me, it's the difference between discharging or actually charging the phone while using GPS.
A couple of notes... this charger does not come with a cable, so you'll need a generic usb type a to mirco usb cable. Nothing special is needed in the cable... you can get a "charge only" or a data version, any cable will be fine. Amazon has some very inexpensive ones with low shipping costs if you search. There are two ports on the charger, clearly marked on the charger itself, a 1A port and a 2A port. The 2A port will NOT charge your note at the AC charge rate as the data pins are not shorted -- it will charge at 500mA, and your phone WILL discharge instead of charge if you are using this port with GPS, etc. So ignore the 2A port unless you have an iDevice you want to charge with it. The 1A port, however, WILL charge your note at the AC charge rate, and DOES put out the rated 1A. This is the port you want to be using for your Note.
So, if anyone is looking for a good charger for the car, that's it. The only negative thing I have to say about it (so far) is that it is a little bit wobbly once seated in the cigarette lighter. Not enough to come out or cause any problems or anything, but enough to be annoying (to me). Nothing a little electrical tape (or any tape) can't fix quickly and easily, though, if it bothers you enough.

That is the other charger I was talking about that is not nearly as good as the one I'm suggesting. With that charger, if you use GPS while the screen is on, your battery will discharge instead of charge. Even without GPS or the screen on, in the best case scenario, it will still charge slower than the one I've recommended. If you're OK with that, then yes I suppose it's an OK charger. It's cheap, looks pretty cool, and seems well built. But for my needs for a charger, I need a) the fastest charger available, and b) for a car charger, I need one that lets me use the GPS on my phone without losing battery life. That's why I searched and found the one I'm recommending.
I personally hate the wound cord because it puts tension on the phone if you try to use it beyond the wound range (which I almost always seem to do), but that's a totally personal preference. The cord is always fighting me when I'm typing on my phone while driving (Not that I do that )

WHAT? Nonsense. First off, the phone is not going to draw more than 1A, and that is a 1A charger. Second, with the big screen on this thing at high power with GPS it's not too surprising if it just maintains its current charge, but in my week of owning my Note I know it does charge while it's on it, and my Nexus One charged on it just fine.
And the cord is very long, not sure where you're plugging your phone in..
OP said he tested the Motorola charger and it only put out 850mA, not 1A. Another poster in a different thread mentioned that his phone still discharged while using that specific car charger as well. So with heavy use it looks like it is possible for the phone to still discharge with the Motorola charger.
Thanks for the info. Had a Verizon car charger for my defunct droid razr and wasn't giving out enough juice to keep the Note running. Heck, it wasn't even able to keep the droid running.
Will look into the ones mentioned here.

I'm not saying the the phone is drawing more than 1A. I'm saying that the motorola charger does not provide the full 950mA it claims (only provides 850mA), and this one I'm recommeding DOES put out the full 1A it claims. Either way, though, there's one thing I know for sure: the one I've recommended above charges faster than the motorola one, and allows your phone to charge in some scenarios where the motorola one does not. It is a better charger, from the aspect of actually charging the phone. The motorola charger might be fine for a lot of people. 850mA is still a good rate of charge, but unfortunately is just shy of being able to maintain or actually increase the state of charge of your note's battery under a common (for a lot of people) scenario in the car -- using the GPS with the screen on. If, however, the motorola charger is working perfectly for you, that's great. I don't care if you buy the other charger or not, I have no affiliation with the company or amazon or anything, I'm just providing the data so everyone can make an informed decision.
The wound cord thing is totally personal preference, I'm not gonna argue that one way or another.

Just FYI I cannot confirm that this charger has the data lines shorted, so you may not charge at the full ac charge rate. Just because it says 1.8A doesn't mean anything. If it does not short the data lines, it will charge at 500mA (half the rate of the OEM AC charger), whether it's rated at 1A, 1.8A, or 1,000,000A.. Sorry if you already knew this, I just don't want any more people getting confused thinking that as long as the charger says it's rated at 1A+ that they will be charging at the full 1A. This is not the case with our Notes (or most/all? Samsung phones). No charger can or will charge faster than your OEM charger, unless your OEM charger is defective. The speed can only be matched, not exceeded.
Here's a scenario using the Motorola charger that is baffling me. I agree with the OP...using my Note with GPS and playing mp3 music at the same time does discharge the oem battery at a slow rate. But if I follow the same scenario, but use a cheap Hyperion 2600mah battery in place of the Samsung oem battery, it actually charges during use! Not fast, only about 3% an hour, but that beats a discharge situation! Why is this?

Great informative post OP! Thanks! I was actually looking into this yesterday and your post is exactly correct. I currently have two Motorola chargers and yup, the Note discharges when using the GPS. I was looking into a new charger and ordered the exact same one you mentioned (in white).
What is surprising to me though is how you mentioned the 2A plug will not output the proper amp, so I have to use the 1A port instead? Do you know why they made it this way? It is just weird how they designed it.
Thanks!

Not 500ma charger
I have a ton of micro-USB chargers that I've used with my GNex and Evo3D with no issue. The only consideration I take into account is Amperage, and I toss the ones below 800 mAh. Last night I plugged into one thats around 850 mAh and left my phone to charge all night (at around 5%). When I woke up, the phone had completely discharged without any sort of recharge.
Since this isn't a Nexus phone, am I locked in to only using verizon branded chargers? Is there a way to defeat that with root?
I haven't had any issues with that as I use all different types. Maybe just try another or maybe it wasn't plugged in all the way.
What voltage is it rated at? It could be that or that the charger is bad somehow. I charge mine nightly with a .7A charger and it's always been full when I wake up (about 30-50% when I go to sleep).
I have the sprint note 2 but they are essentially the same phone so here is what Igot for you:
there is no "smart" element to any chargers in the market, so your phone shouldn't know the difference between Verizon brand and the devil's own brand
if you look at the stock charger it outputs 2 amps...the phone needs this and in my experience it needs at least 1 amp in order to charge instead of discharging slower
also there is a known issue with all note 2s that the cable will not sit snugly inside the port causing it to be a bad connection... just make sure you put it in hard (no pun intended) and it shouldn't be a problem

Yeah, if you take a close look at the micro-usb port, it is recessed a bit. Make sure you plug the cable in firmly.

I think this was likely the issue. The charger is rated at 1 Amp, and I tried it out again last night and it appeared to work for the few seconds I had it plugged in, so I must not have had it in there snugly.
So I just tested with the same charger, and when I plug it in, it beeps every half second and flashes between the charging/discharging symbol, and does not charge...

I don't remember where, but I remember reading about someone with this issue where they were using their phone as a gps while charging it and it died. Someone commented saying that the culprit was probably a faulty charger. Sounds like they were right.

I have seen this same thing with two Droid X's plugged into the same 2A charger. One phone would charge and the other would do exactly as you describe. It didn't do it all the time, it just depended on how low the battery levels were on each device. How much battery life do you have left when it does this? You may just need to use a higher amperage charger.
I have not received my Note II yet, but it sucks that I will most likely not be able to charge it while tethered (USB) to my laptop.
Based on the info I could find (kernel driver), the phone will accept up to 650mA of power, so anything over that should charge the phone at the same rate. Voltage shouldn't be an issue as it is charging via USB, which is 5V (+/- 5%). Unless someone has an amp probe to put on it, we can't tell if it is actually pulling more or less than what the driver specifies. And, as someone else stated, the phone can't tell if you're using a genuine Samsung cable and charger, or a $1.00 made in China cable/charger, as long as they both output the same voltage/amperage, the phone will never know the difference.
Based on what you said though, if the phone is constantly seeing the charger connect/disconnect, that would drain the battery even faster.
Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

Same here, 2a Nexus 7 brick with a long Logitech USB cable, much faster than stock (and longer)

I'm fortunate my car has a built in inverter that I use for charging my phone.

My next car will too, because I can only imagine that power requirements for these devices is going to increase.
That said, I think I have a winner, and instead of retyping my posts, I'll just link to that thread instead: http://forum.xda-developers.com/showpost.php?p=41797839&postcount=6
Since the snap Dragon 600 has fast charging capabilities, why didn't HTC Include it in the kernel??? I've noticed my 2500 mAh note battery charges faster than my 2300 MAH HTC one
