The stock moto wall charger that comes with the phone has the following specs:
100-240v ~ 50/60Hrtz
0.2A
output 5.1V = 850 mA
I've been interchanging between the stock one and my old Galaxy-S one, which lists the following:
100-240v ~50/60Hrtz
0.15A
Output 5.0V = 0.7A
Does the slight undervoltage make a difference? I'm wondering if this is what has been causing my battery issues ? Anyone else use anything other than the official moto charger to charge their Atrix?
I didn't think it would make much of a difference since when you're using the car charger, you're not using exactly the same specs either ... ?
Any info appreciated, thanks!

Should not make a difference. USB is rated from 4.7v to 5.4v and 500 mAs the charging spec is 1 A on the phones (technically charging spec for USB is anything "safe"). USB is considered 5v so actually the Galaxy-S one is more "perfect" for the specs.
I have a 1A charger that will not charge my Atrix but it will charge my old Fuze.

I was readin last night after posting, looks like 850 mA is the charging max for Atrix, it says any higher and it will trickle charge for safty. I don't have the link because I am at work but I think it was on the support forums at motorola.com
So I went on a 2 hour trip using my EVO as a gps. I had it plugged into the car charger the entire time. Little did I know the EVO was using the battery faster than it was charging. I've done this many times with the EVO 4G with no problems. Any suggestions? The phone is basically useless as a gps for any long distance trips. The battery will never last.

get current widget, it tell you how fast your phone is charging, and when unplug how fast your phone is draining in mah, note your mah usage when unplug, then note your mah usage when battery is fairly low and plugged in to charge with the car charger.
if your battery is low (below 50%) and your phone still won't charge faster than 500mah on the car charger, it will not keep up with GPS uses, be aware that as the battery approach full, it charges slower and slower, near 97~99% it will only charge @ about 100mah rate.
I bet you have a cheapy car charger that only supply 500 mAmp, get one that can supply 1000 to 2000 mAmp (1A to 2A... 2A usually for DUAL usb outlet type charger)
deleted... double post hmmm
Mine wasn't charging unless it was plugged into the wall until I typed ##3828# and checked "enable USB charging". Now it charges while plugged into a computer or car as well.

Also, I have a decent charger. It's one of the ones that has two ports on it. By the way I was only charging the EVO 3D I didn't have anything else connected.

I've never had a problem using this older but more powerful iGo AutoPower 3000 car charger. Overstock has them for $6.50+shipping and you get a bunch of power tips with it but not a microUSB tip.
http://www.overstock.com/Electronics/iGo-AutoPower-3000-Car-Charger-Power-Adapter/3668307/product.html
The power specs on the package I have say:
DC Input: 11.5-16 VDC
Power Output: Up to 15 Watts continuous
Radio Shack sells the iGo a97 tip for $10+taxes but Amazon has the tip for $6+shipping(free shipping if you have prime).
http://www.amazon.com/iGo-Kindle-Motorola-RAZR2-KRAZR2/dp/B0012J52OC/ref=sr_1_1?ie=UTF8&qid=1310316568&sr=8-1
From my understanding, the tips have a resister in them which limits the mAmp output but I'm not sure what the a97 tip specs are since iGo doesn't seem to release that info. Hopefully it's 1A like the wall charger. I can verify that the newer single output iGo chargers are limited to .75A. So even if the tip is 1A, the charger is the limiting factor, hence why I recommend the older, more powerful one.

Read the label on the charger, make sure it say at least 1A or even better 2A
lots of cheapy dual USB on ebay that's not rated for 2A
if you got a 2A charger and current widget still show 500ma charge rate,
then you may have to figure out if your phone is charging in USB charge mode with the car charge (limit to 500ma by the phone per USB spec) or in AC charge mode (charge at up to 1A)
I just came across this other day that point out this problem.
http://www.amazon.com/gp/customer-m...B9U8Q/ref=cm_ciu_pdp_images_3?ie=UTF8&index=3
look at the mouse over box comment... of course every charger is different so don't just blindly do the mod if you have a different charger.
as for the other guy asking for 2A charger....
Ebay and Amazon have alot, just make sure they specificly say 1A for single USB or 2A for dual USB output.
for 2A dual USB, the OEM HTC thunderbolt one seem to be the best but also most pricey, some alternative are the Motorola dual usb and the Tmobile my touch 4g dual USB

Was having the same issue;
I used the car charger I had for my EVO, left it on for 3+ hrs, with little to no increase from where I put it on at. Ended up using a buddy of mine sharger and viola. Imex99 explained the reason for it. Just buy a new charger with 1A/2A output rating and you'll be good.
I'm having the same issues. I click enable usb charging and then commit, but it keeps reverting back to disabled with no difference in charging capability.
Speaking of car charging, why does the battery temperature vary so much between AC & USB, versus Car charging?
With the supplied HTC AC charger or USB connected to a computer, the battery's charging voltage is 4.333 volts and the temperature is 81*F.
With a Sprint Car Charger, the charging voltage is 4.333 volts but the temperature is 95.5*F
Even chargers rated at 1A/2A may not have the appropriate pins soldered together to enable 1amp charging. Please see this thread I made when I had the Evo 4G:

Hello guys,
Like most of us Android users I had some previous phones that were Android powered...
So with Motorola Milestone I had a 12v car charger, I used it too much with it, now I have a Galaxy S2, if I use the Motorola's charger to charge my phone there will be any problem?
Thanks in advance!

I use my sony charger to charge my HTC evo3d.no problems so far.but iam not sure about Motorola
Sent from my LT15i using xda premium
The important part here is the voltage the car charger outputs. I believe the standard Galaxy S2 outputs 5V (at 700mA [0.7A]). If the mA is lower, it will take a longer time to charge. If its higher, it will only draw from it what it needs.
So, check the output voltage of the charger is not higher than 5V and you should be ok.

I'll use it now without any worries so!
So I will get the regular charger for gs3 that comes with the phone (tomorrow when i get the phone). but i also have the HP Touchpad charger which gives output of 2.0A. I was wondering if I charge my phone with the HP charger will it actually charge is faster then the regular gs3 charger? the reason i ask is cause in other threads ppl have mentioned that it only charges faster with non - stock roms like aokp or aosp roms. please lemme know if this will work. thanks
It should I got one of those and it does charge faster I got the bb one tho

I've used my BlackBerry PlayBook charger on mine and it doesn't charge any faster. That charger is 1.8amp.
It will not charge faster. The phone only draws as much amps as its allowed to. Whether you use a 1 amp charger or a 2 amp charger, it'll only charge at the phones own rate

I don't believe so. The phone only draws what it needs.

A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

Unless you run a custom kernel that allows for higher charge rates.

I have a dual car/wall charger and I noticed when plugged in the car it charges faster.
Sent from my vivow using Tapatalk 2
The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

the only way I have found to charge phone's faster is to power it off and then charge...takes about half the time to fully charge
none of the 2 amp chargers make it any quicker

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
Just got my Nexus 7. It has a charger that outputs 5V 2.0A.
Anyone know if it's okay to charge the rezound with 2.0A output? Any experiences?
I don't want to carry around two chargers and if it's okay to use it to also charge the Rezound, 2Amp is faster than 1.
Thanks.
2 Amps is a lot for a USB charger. You should be fine though. Its a power rating, so 2A is essentially what the charger is capable of. Your phone should just use the power it needs, I don't believe it will always put out 2A.
Sent from my ADR6425LVW using xda app-developers app
2A chargers work fine. I use my Rezound with my 2A Touchpad charger all the time and have no problems. It'll only draw as much as it can use, no matter 1A or 20A.
