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!

Greets - I came from the Incredible, so I have a BUNCH of chargers (car and wall). Does anyone know if these will work with the Rezound, or if I have to buy a new one (I know Thunderbolt stuff would work; but I didn't have that phone).
Also, anyone know why the phone would flash orange, while off, when plugged into the charger for the first 30 seconds to so, before going solid orange to charge?
If they're microusb and the charger can output 5 volts and at least .5 amps, it will charge. It will charge faster with a charger that can provide more amperage, but that's all.
I use my Incredible charger and USB cable and everything works just fine. The wall charger is actually the exact same charger. As for aftermarket chargers I would assume they would work seeing as the device charges on standard 5v 1A that most USB chargers provide.
I am using the same stand alone charger I used for my Thunderbolt.
Flashing Orange
I prefer to charge the phone with the power off, so it gets a full charge. When I plug in a charger it flashes orange for up to a minute before going solid orange to charge (ultimately going to full green). Any idea what flashing orange means ESPECIALLY in a powered off (but plugged in) state?
Mine never has blinked, just shows orange til charged, then green.

I think that the orange blink has something to do with either battery temp or when the battery is fully dead. It happens to me to. I wish the manual had more about it...

I still have a few 5V 700mA blackberry chargers lying around that I use if I have to, but I prefer the one that came with the phone (or the one that came with my dinc -- same output specs) because it charges faster.

Punman - THANKS! You are right that my battery was completely dead yesterday. I had charged my first Rezound before using it, but the 2nd one was with whatever charge was on it from the factory. Had been trying to load it up and get it up and running, and was less than 10 seconds from shutting it down smoothly before it ran out. In fact, I was in the process of the shutdown procedure (already hit shut down), but it ran out before it could finish. We'll see what happens tonight.
If the LED is flashing orange it means the phone is unable to power on, for either reason it is too hot, or too dead. Once it goes solid it is charging and is able to power on.
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.
When plugged in, the charger included with my Optimus G buzzes. Audibly. It's pretty loud. At first I thought a fly was in my room, then I realized it was coming from my charger.
If I unplug it, it keeps buzzing for about ten seconds.
I have a Nexus 7 charger and a Atrix 2 charger. Neither have the same specifications as the buzzing LG charger. The N7 outputs 2 amps, the Atrix outputs 0.85 amps, the LG outputs 1 amp.
So... is it safer to a) use the buzzing charger or b) use a non-buzzing charger, but one that outputs a higher/lower current than the included charger?
I'm now afraid to charge my phone.
Anyone else having a problem where the charger buzzes?
Thanks.
UPDATE so apparently some googling tells me that it IS okay to use other chargers AS LONG as the voltages are the same. Amps can vary; even if the charger is rated for more amps, the device will only take as much as it needs, and if the amps are lower than the device specifications, it will just charge more slowly.
So my N7 charger has the same voltage but higher amps, so I'm just using that until LG sends me a non-buzzing charger (if they ever return my request)
If any of this information about volts/amps is wrong, someone let me know. But it seems right according to my limited knowledge of physics.

Never seen that before. Had a lot of phones with a lot of chargers and never heard a buzz, I'd get a new one just to be safe...but I tend to be super cautious
Weird, my charger (that I got with the OG) buzzes as well. I've been using since I got it and it hasn't exploded....yet.

Interesting... so it's not an isolated issue. My phone is four days old, which is why it's frightening me. I think I'm just gonna submit a replacement request, and keep using the buzzing one until that one arrives (assuming it's granted and I don't have to deal with any bull from LG). If it's a common thing for the charger to buzz and yet no one is complaining about an exploding battery... it's probably safe.
But I'll request a replacement just to be safe.
My htc inspire charger has always buzzed when plugged in to the wall but not charging the phone. My guess is it is a function of the transformers magnetic field and some metal part in the charger.
My charger buzzes too, when is plugged in and for a few seconds after like you described. I've been using it since launch day on this phone with no issues. The buzz has not gotten any louder or anything over the past few months so I wouldn't worry about it.
Running SnowJB
Switching power supplies like our chargers sometimes do buzz because of the way they work, and it may or may not be an issue. Usually it's an inductor vibrating, and it may last as long as you need it to, or the vibration may cause eventual failure), but since yours is still under warranty I'd definitely replace it.
Using any other USB charger will not be dangerous or bad for your phone since the voltage is standard. If it's rated for a higher current, great - the phone will only draw as much as it is designed to, so you can't damage anything that way. Battery monitor widget appears to tell me that it only charges with about 800mA of current (that is net; the phone is still using some additional current to operate), so assuming the correct current is being reported, it doesn't appear that there's any benefit from using a charger that can supply more than 1A. Unless it can draw more quickly when charged with power off -- I don't have any good way to check this.
On the other side, while you can use a charger that's only rated for 500mA, which is the old USB standard current, the phone will charge more slowly and you'll probably get the warning saying so. It may not actually even supply enough current to charge the phone while you're using it in that case. So while you'll get by in a pinch for an overnight charge with one of those, it's well worth investing a couple of bucks in a higher-rated one.
I normally use my kindle fire charger which is rated for 1.9A (and the Fire can draw that much) or my New Trent battery pack which is rated for 2.1. My LG charger stays at work and doesn't get much use. I'm going to eventually buy another charger for home and I'll be looking for one rated for 2A or so.
Beeping
My charger is beeping after the battery is full. Its very very quiet but I hear a rhythmic beeping.
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.

Hi everyone,
I have just swapped my Galaxy S3 to a HTC One X+ because I couldn't stand Samsung's Touchwiz, and I love Sense 5. The downside is the charging times on this new phone are pretty laughable!
Now I know different cables can give different currents consistently, but I have three cables (one at work, one in car, one at home) that would all deliver 1000mA to my GS3 and I could go from 10% to 100% in about 90 minutes, about 1% per minute, it was great! Battery life on this phone never degraded so I know 1000mA wasn't damaging at all (all GS3s can take a maximum of 1A).
I've now moved over to the HOX+ and it's taking absolutely forever to charge, between 3-4 hours to charge from low. I simply can't wait this long, it's beyond a joke :crying: I've checked Better Battery Stats and my battery usage is about the same as my GS3 when unplugged (about 4-5% per hour) which is fine, so why the difference in charging times?
On my GS3 I had an app which showed me charging current that was specific to GS3s and was very reliable, but I can't seem to find a reliable app for the HOX+, the one I have is Battery Monitor Widget and it reckons I'm charging @ 330mA and I'm currently at 22%, that can't be right can it?
Here is what my phone is says when charging "Charging (USB)".
In the past hour it's done about 20%.

Erm thats the issue. When you charge using the AC (By cable to the electric socket) it says "Charging(AC)" . This usually takes me from 10-100% in about 90 minutes with the HOX+.
Somehow either you are connecting it to a usb hub (laptop or a computer) which is pretty slow compared to the AC, or your phone is mixing up the AC and USB currents. So an advice, use an electric socket and make sure it says "AC" in the power tab. IF so, check the charging time you should find it similar to that of Samsung.
I also think usb 3.0 is faster in charging than 2.0 ? If you are on a new pc with a new motherboard you should find your sockets 3.0, so don't use a usb hub especially if it says usb 2.0 since it will be pretty slow.
Hi Gand0ur, thanks for the advice.
I should have said before; I never charge via a computer/laptop/USB hub. Only directly into the wall. It is an aftermarket charger but it's a good quality one as it charged my GS3 @ 1A and also my old Sensation charged in about 90 mins.
I've just tried a different cable and still the same outcome. I'll try another wall plug when I get home tonight

That isn't necessarily true. This charger has been the fastest thing to ever charge my HTC Sensation and GS3, and come to think of it my Nexus 7 charges faster with this charger too. As I said earlier, I had an app on the GS3 which showed it was outputting 1000mA (maximum the GS3 allows) and it would charge that phone in around 90 mins. According to the HOX+ app I have I'm only getting 330mA. Whilst I agree that poorer after-market chargers often give dubious results I'm confident that this isn't the charger's fault.
I'll try the a HTC charger when I get home, but the other night I had it on charge with the HTC charger and it didn't seem to move very quickly.
I'll just say what I know from experience with my HOX+: it only seems to be charging in a normal (and pretty fast) way with the original, from the box, charger.
I tried charging it with the charger from a Desire Z - slow; charger from Desire S - slow; a Nokia charger - slow.
I also noticed that while the Desire S or Z can get charged while being used, when using a car charger (a Nokia one), the HOX+ seems to be using more current, and it ultimately dies. It happened this summer, so this might be an issue.

I also noticed that while the Desire S or Z can get charged while being used, when using a car charger (a Nokia one), the HOX+ seems to be using more current, and it ultimately dies. It happened this summer, so this might be an issue.

I think you're right! I tried my wife's HTC One S charger last night (because the HOX+ doesn't come with one) and it changed to Charging (AC) for the first time. I have to say this is a massive let down for me, my car charger saved me so many times with my GS3 (for example I drove to Scotland and used GPS all the way, and the phone still charged right up at the same time) I'm not sure I can handle it not being able to cope with other chargers.
I find this extremely frustrating Is there not a hack to get around this with root?
I'm not sure about the Samsung, but the HTC will only go into the fast/AC Charging mode when it see the Data+ and Date- signals shorted on the USB port. This can be designed into the charger, such as the factory HTC wall charger, or you can buy "charging only" cables and then use any USB charger to get your HTC to go into AC charging mode. These charging only cables are tough to find, but amazon does sell them. Keep in mind that the charging only cables will not transfer data at Data+ and Data- are shorted. Once you are in AC charging mode, the phone takes over and determines how fast to charge. At low battery levels (less than 80% or so), the charging rate can be as high as 1000ma/h or the maximum the charger is rated to deliver. If the charger is rated to deliver more than 1000 ma/hr, the most your phone will draw is 1000 ma/hr.
Now there is another variable, the cable itself. Cheap cables sometimes have too much resistance to pass 1000ma/hr and can be the problem as well.
One other issue is the number of knock off chargers and cables out there. Beware of e_ay. You may not be getting what you think you are.
One final note, Apple designs the ipod to look for the Data+ and Data- signals to not be shorted (opposite of HTC and most android manufacturers). So chargers that are designed to charge Apple devices will need the Charging Only cables to charge android devices in the AC charging mode.
So if I didn't confuse myself, hopefully this will answering some charging questions. I've researched this and have tested many chargers and cables.
