Motorola OEM chargers only?

Last night, I decided to use my HD2 charger, since it was already in my drawer. Charged it around midnight and woke up around 4 and it only charged 10% So I decided to use the Motorola charger, and when I woke up around 6 it was fully charged in less than 2 hours. So my question is, are we only suppose to be using the charger that came w/ it or is my outlet possessed

The actual cable doesn't matter, but the charging port seems to. My phone doesn't charge as well when hooked up to my HTC Aria's usb charge vs. the one that came with my Atrix or even the old Motorola Z9 charger I have (like this one since it's longer than my USB cable and it reaches my bed so I can do "Sleep as a Droid"

I tried using my Nexus charger last night and the phone didn't like it at all. It started FC'ing all over the place and I had to reboot it. The voltage on both chargers are the same. For a moment I thought I f'd it up but it's been fine all day.

I'm using Blackberry's micro usb chargers with no problem. I bought a few of these for my N1, and they work fine with the Atrix. The N1 charger from Google/HTC does not work like you all have said.

Check the amp output of the charger, a good one will be at 1amp, where most are around 500ma or less.

If you're having charging issues, it's probably because the charger isn't supplying the required 800ma draw. Most USB power adapters still only output 500ma max. Be sure your 3rd party charger can output 800ma or more. For example the Apple USB adapters can output anywhere from 1000ma to 2000ma and they work great charging the Atrix.
Hope this helps!

Yep to both. I tried my N1 charger last night, and the Atrix wasn't having it. Tried my BB charger at work and it charged up quickly. It's weird. On the plus side, a second usb cable is only 6 bucks from at&t ... which is fair.

The Atrix must be a little charge sensitive (maybe it has a rapid charge mode or something). We have at our counter a surge protector that also has two built in USB ports for charging. We've charged our iPhone 4 and my Captivate at the same time for months.
When I plugged in the Atrix, it starting chirping (like switching the charge mode on/off/on/off) and the iP4 _also_ started flipping out (again, like the power was being interrupted).
I wound up plugging into the same surge protector, but used a regular AC outlet and the supplied USB>>AC adapter. Everything ran/charged just fine.

Mine seems to freeze up and force close often whenever I charge it with my blackberry cord. The same cord had been charging my Backflip fine for months.

Need the Amp rating
I don't have an Atrix yet (I will soon).
The Blackberry charger that I have puts out 700mA.
But I have tried to use other micro USB chargers with the BlackBerry (BB) and if the charger does not put out the right amps, the BB keeps flipping into/out of clock mode. If you then plug in a BB charger....works great.

A USB-Port is only supposed to deliver 500mA by norm.
So, to charge the phone it hast to be >=500mA.
That explains why the Atrix charges really slow hooked up to a PC, since the battery is ~1900mA/h
You do the math

I'm using a Samsung wall charger right now with no problems.
Has anyone tried using an apple charger/aftermarket apple chager on their Atrix yet? I have an incase combo charger that can feed 2 amps (necessary for the ipad) and I'm worried it might cook something.

Thanks for all the help everyone. I decided to just stick w/ the Moto one for now. Sure does take freaking forever to charge via usb on your computer. Lots of juice power

I just got this charger from Amazon fro $5.99 with 2 day shipping (if you have Prime)and it is OEM !

I've used my wife's captivate charger, and it seemed to charge just fine, will need to look and see the output.. I may need to try my Iphone charger and see the rating...

The B&N Nook charger works fine too.

i forgot to bring my charger to work today, phone died. then i found a charger in my desk for an old bluetooth headset i no longer have. 5v-550ma......seems to be working but i suppose we shall see

I have been using my HTC Evo charger without a hitch.

[Q] Slow Charge

Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?

When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.

Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.

you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs

When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.

I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?

Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.

Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.

Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.

Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here

Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.

the 2A chargers from BlackBerry are the best

So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

Battery draining while plugged in to charger

I was watching the Mavericks vs Thunder game using the watch ESPN app and my nexus battery was at about 93%
I watch since halftime to the end of the game and I was plugged in to a car charger the whole time and when the game ended about 1 1/2 hrs later the battery had dropped to 53%. Can't understand it. Hope someone here can explain this to me.
Phone is galaxy nexus, obviously, the battery is the 2100 OEM battery from Verizon store, charger is a belkin dual outlet 1amp micro car charger with the cable that came with a Droid charge.
Thanks in advance ladies and gentlemen, I did look and search, didn't fins anything covering this specific issue.

5V right? that's not a huge draw at all on your battery, i'm assuming your car was either running or started right up afterwards...you can be certain your phone was getting that full 1A especially if your car was running. if your phone showed charging and your phone will normally charge from your car like that then you shouldve been in good shape. despite what you may think, i actually am trying to present relevant info lol but ummm other than that? i would definitely try a multimeter (.....if you have one.....) cuz that would show you exactly what you're getting in/out. usb pinouts should be somewhere on the internet. other than that, try doing the same thing (except for maybe a shorter time period if preferred) on a wall charger which should be more reliable and compare results. i've had devices that burn power faster than they receive them....but the good ole gnex? im not so sure. (engineer here).

I just recently join big red and coming from sprint with an evo 4g and didnt have this issue with that phone and same charger. I'm definitely going to try it with home charger to see if its the charger.
Extra info, the vehicle was powered on before I plugged in the charger, in case it matters any.
Thanks to all the reply thus far.

I find that under heavy usage, only the plug in wall charger gives enough juice to keep it increasing... and even that can go flat or decrease if you are really pushing it... also the way the battery stats are displayed can be flaky too... jumps in the level of charge and quick drops... hard to tell how accurate the reading is.

I hear you. That's crazy, basically the phone draws more power that the charger can provide. I would think the charger should be fine since its 1 amp just like the home charger.

Check in settings - status if it says charging (ac) or charging (usb) when plugged in you car.
If it says charging (usb) the charge amps are limited to 500mA.

The phone can use more power than a car charger can supply. This is commonly posted all over. Check your car charger, its likely a 0.5 amp. Buy a 1 amp or higher.

Your problem is the charger, 1 amp is the sum of the two outlets, hence you're only giving your phone 500mA max. When charging at that low of a rate, you'll drain the battery when doing anything power intensive on the phone. Your only remedies for this is to get a car charger that's capable of putting out 1 amp or more on a single line. What I personally did was get the Griffin Powerjolt dual charger for $8 on Amazon, opened it up, and soldered the center data pins on each port together.

I though that the griffin powerjolt dual outlet charger would dish out 1amp on a single port if the 2nd port was not being used. Interesting, I can see your point. Would you happen to have a picture of, or remember which are the two that need to be bridge inside to make it a full 1amp output?
Thanks in advance.

Okay, I tried what you said and I got weird results. I used the awkward griffin powerjolt dual outlet car charger. I tried using two different cables, one was from my girl's Droid charge and when I plugged it in and check the status it said usb charging, then I plugged in a cable that came with a i go green adapter that I had purchased at an airport and the phone said ac charging. Unless the cable that came with the Droid charge can only pass 500mamp, I'm puzzle.
Both were plugged in at same time and also both cables were tried by themselves in each outlet of the griffin charger by themselves.
Interesting huh. I will keep testing and see what gives, last resort I get a more powerful car charger. Will keep you guys posted, thanks to everyone that contributed and pitch in thus far.

Got an update on this issue. I streamed another 45 mins to 1 hr of ESPN using watch ESPN app and the results are even more interesting. I was using the wall charger that came with the Droid charge and the USB cable that came with the I go green wall adapter that I have purchased at an airport a while back. Here is what happened, when I started streaming the battery was at 94% and I plugged in phone to charger and under settings/about/status it showed AC charging. After 45 mins to 1 hr of streaming the phone was extremely Hot towards the center of the back and below the cam lenses and led light. Also the battery had dropped to 93% and the phone status showed not charging, even though the battery icon on home screen next to clock shows the lightning symbol inside the battery like is charging.
I don't understand what is happening. Grrrrrr. This is using a wall a charger for a droid charge. Now of to trying it with the OEM charger and cable.

Exactly, in the driver i think the overheat is set to 140F. Also when your charger showed as usb it only gets 509mA and when showing ac it gets the full 1 amp. So just pay attention next time and see if it drains when showing ac.
My car charger is a 1.3 amp and always shows as ac and never drains while charging.

I though about that but then I was wondering, shouldn't the wall charger provide enough power to run everything in there while charging the battery or even without the battery in the phone. Like shouldn't the battery hold the charge that it already has when I started streaming as long as the charger is 1amp?
I would not care if when I stream the phone battery would just hold its charge at what it has at the moment even if it does not charge while streaming. Hopefully that is clear to understand.
To all the fellow galaxy nexus owners out there, maybe you all can test on your phones and see if you get same results as me. Download watch espn and stream the channel for 30 mins, notice what is your battery level before you start streaming, of course plug the phone to a car charger or wall charger and see if battery remains the same, drops charge, or gain charge at the end of 30 mins, or maybe an hour. I am not asking you to watch it for the 30 mins or 1 hour, just let it run and see what happen, if you can of course. only reason why I ask for watch espn is because it is the app that I have been using to stream nba games for the last few days.
Another thing since I am already here with this streaming issue, I have an original SlingBox, the cheapest of the cheapest when they first came out, just coax and that is it. I would like to know if I pay the $29.99 for the app from the market when i switch roms on my galaxy nexus would I lose the app? I have already unlocked and rooted my galaxy nexus and lets say I buy the app and I am running cm9 when I purchase it, if I change to gummy rom or back to a stock rom while still rooted would I have to re-buy the app ?
Thanks in advance for all the input.

No I haven't try that. I am currently testing out roms like a mad man trying to find the best for my liking. Question for ya, As far as I know that is kernel dependent right? Like the kernel has to support it, if so which kernels do support it and what would be good underclocking settings ?

I get similar results while using navigation and pandora at the same time, the phone uses more juice than the car charger can provide.

Ironically I plugged in the oem charger and oem cable from the galaxy nexus box and open it (didn't really wanyed to do that) and streamed 30 mins of espn on watch espn and battery was at 70% when I started after 30 mins streaming it had actually climb to 78%. Confused yet everyone? What gives?
Sent from my PC36100 using xda premium

Not all that odd. Using my Fascinate charger (0.7 amp) I get noticeably slower charge times than the OEM charger (1 amp). I don't use my phone much while I'm charging so I can't provide any feedback for that.
What is the Droid Charge charger rated at?

Battery or Phone?

Friends,
Interesting observation here. For the last week of owning the SGIV phone, my battery life is awesome, however when
it comes to charging it takes *forever*. When I mean forever, I don't mean two to three hours, like almost 8-9 to get a full
charge.
11:30am est battery was at 17%. At 3:30pm est, battery at 47%. when charging.
Any ideas if its the battery or phone?
please advise,

It shouldn't take that long to charge. Mine charges with a way higher rate. So I guess it's a problem with your phone /battery
Flowed from my GT-I9505 using xda-developers app

Proly an issue with the charger - i charged slowly from a computer outlet - but a couple hours later did the wall outlet (using a motorola charger and it was juiced up in a just few hours) - Might be related to the charger and/or usb cord in use.

Make sure you are using a 2A charger like the one that came with it

I was discussing this with a friend after I posted my concern.
Apparently, if you charge by usb from a computer source, the amp is lower hence, it will take three times longer.
If charged by wall outlet it won't take long for the phone to charge quickly.
Just in a half hour I decided to test this theory and it works faster at wall outlet.
Thanks people...

not sure if this was mentioned in the FAQs and I did look.
Might want to add this in the FAQs - differences between the battery outlet charging vs. computer source.

Normal usb power is 5.1 volts at 1amp. Bigger battery chargers are normally 5.1 v but at 2amps.. that being tablet chargers and bigger battery devices.
Plugged into a comp and not into an outlet I think you get 1/2 an amp ( wayyy less then originally supplied and intended charger)
our s4 came with a 2amp charger. You can read the specs on the side of it.
if you were using a 1amp ac adapter which is what 90% of mobile phones have, then it would take significantly longer.
my battery charges in about a hour and twenty minutes using stock s4 charger and cable.

Extremely slow charging with micro USB 2.0

This weekend I manged to leave my included Note III Micro USB B 3.0 charger at a friends. I didn't think it was a big deal because I knew I had plenty of micro USB 2.0 Cables I could use in the meantime as they are supposedly backwards compatible.
I was home watching football for most of the day yesterday. The phone charged all day yesterday but I don't remember it ever getting as high as 45%. I didn't get worried until last night when I looked closely and realized the percentage was declining as I used and charged it.
When I went to sleep at about 12:30am I was at 9%. My WiFi and 4Glte were both off and I wok up at 5:30 am to find my phone at 63% only after 5 hours. This is the same charger I used with my Samsung Galaxy S3 just over a week ago til I got this. Why isn't it charging. I'm afraid I'm harming my battery somehow. That's why I'm writing this at 5:45 am instead of sleeping. Any help would be appreciated. Thanks.
P.S. In the 10 minutes it's taken me to write out this thread my battery has declined to 62. (Still on charger)

I had a usb2.0 cable plugged in in my car and I went skiing and streamed music and did the same while plugged in on the way home. I don't know if the cable just slowed battery usage or not but it was plugged in for 2 hours on the way home and I still lost like 5% while plugged in. I bought a USB3.0 cable off Amazon and it works well in my car, not as fast as plugged in to the wall charger but much better than 2.0

I understand that 3.0 will be faster but this is horrendous. It's now 8 hours since I plugged it in and I'm at 74%. And it's plugged in to a wall adapter not a computer or car. Haven't even had this phone for two weeks. Samsung you're killing me here.

It's not, at least, not from a wall charger that follows the specs. USB3 will charge faster from a computer with the drivers set up properly, but the stock wall plug is 2A (max), all the time. If you get better charging from a USB3 cable, your USB2 cable is probably using really thin wires or just is wearing out.
Some generic chargers are all over the place. Some don't short the data lines so the phone doesn't know if it should be able to fast-charge. Some don't actually put out the current they are rated for.
IF you use the charger the phone came with, and a GOOD USB2/3 cable, it will charge properly. If its not, you have something wrong in your setup. I use the charger that came with the N3 (and the N2), and a Nook or a Monoprice.com USB2 cable. Nice fast charging. I have never used the USB3 cable as I prefer to be able to charge other devices from the same cable and I don't own any USB3 computers.
I also get good charge speed from an older HTC 1A charger. Not as fast, but faster than I expected to get. Note that's a charger that came with a G2 and G2x, not some ebay crap. That's not to say that generic ebay chargers can't be good chargers, just that many of them aren't. If in doubt, use all OEM stuff, at least for testing.
What's probably happening for most people having slow charging on older and/or generic charging setups is one of these...
1) The charger doesn't short the data pins so the phone thinks it's connected to a computer USB and limits charge current to 500mA.
2) The charger doesn't output what the writing on the side claims, and the phone detects this, so it limits itself to charging as best it can.
3) The USB cable uses small, cheap wires and creates too much voltage drop, causing the phone to limit its charge rate.
4) Connector wear is causing voltage drops due to a bad connection. Try a new cable. Not a different cable, a NEW cable.
5) Your Note3 is defective and needs to be replaced. This isn't real likely, but damage to the USB port could cause it.
The Note wants a lot more current than older devices. It also has a system to detect issues that older phones didn't have. I think the first I saw with it was the N2. The phone detects voltage fluctuations under load and adjusts its current draw to keep the voltage as steady as it can. This makes the device more picky about having a good charger and cable. That can be a pain, but it also prevents overloading the charger, which could be something expensive like a computer, which prevents damage. Note that this doesn't harm the battery, it just won't charge as fast as you might like. At 500mA, it's actually possible for the phone to use more than that, so your charge will go down while plugged in. That's not going to hurt anything, it's just how it is.
For the OP: Try a decent wall charger. If you don't have anything better, you'll have to turn the Note OFF while charging. That should at least get your battery charged overnight. If it's a long cable, try a shorter one, that can make a difference. Or try to find a thicker cable, but that's not always a guarantee the wires inside are any thicker.
