Recently my wife broke her USB port on her n7, so I decided to just attach some wire to the pogo pins as I know there was a ground and a 5v line. After I installed battery monitor, hers was charging at 1000 to 1300ma. Mine charges at 500-600ma.
Maybe my port is broken too I'm not sure. Can anyone confirm this?

Hi I use the dock to charge my n7. I have noticed a faster charging rate. However i do not know how to measure this

I also charge my nexus from a homemade dock at the 1000-1300 mark compared with my usb port. The usb port is so bad that most of the time I see it discharging while in use!!!
I believe this is a hardware fault as mine used to charge great through usb. at one point my usb socket stopped working altogether, I ran a soldering iron over it and it is at least working again, still slow to charge.
I have also been following a thread about this in the google user forums. One person stated that when they changed the usb board charging rates resumed to normal standards. There is a lot of people in that thread suffering from this. Bad show google.
Have you guys confirmed that the n7 charges faster off the pogo pins?

It can charge just as fast off USB I know mine does I think the problem seems to be that the ports are easily damaged and it slows the charge rate

I have been following a thread on google forums about people suffering from poor charging rates. I can confirm that many users in that thread, myself included, have found that charging through pogo pins charges normally, whilst the usb charging takes forever and even discharges with screen on!!

is that with the provided 2 amp charger?
It is with a third party charger as my charger broke, but it was the same with the original.
Sent from my Nexus 7 using Tapatalk 2
The 5V oem charger output 2000mA. Any charger 2A should fast charge.
Also the pogo pin can charge on 12V 500ma (which is automobile acc. standart)
See more info on Qualcomm FastCharge Standart
There's a chip that identify the power output available. So a charger 1A charger will be identify by the device, therefore it won't fastcharge.

So the wall sends out 1000 ma and USB sends 500 ma.
What about webtop? Anyone know?

Hey thanks! I already have a dock though.
In my post I asked what the charging output was for the HD dock.
Sent from my Atrix using XDA App
USB 2 is 500ma, USB 3 is 900ma, Moto charger has 850ma rating on it. If you have a USB 3.0 port you can use you'll get enough power from that. I use the 3.0 on my laptop at work, and it charges fine.
How can we find out the charging output of the multimedia dock?
Sent from my Atrix using XDA App
Do the differences matter much? Just one takes longer to charge then the other?

Yes one charges faster that's it. For heavy users like myself, getting the most juice as conveniently as possible is a plus.
I also like to charge my phone on the dock and keep my usb cable in the truck for playing music. I only want to do so if I can find out what the dock is putting out. When I need juice I need it as quickly as possible.

If your only getting 500mA your phone will take hours to charge and then only if your not running wifi, Bluetooth or gps. Use any of those and plugging it in will just prolong discharge but not actually charge it. With just GPS running I pull over 700mA. I'm really tempted to put a female end with resistors (to fool the phone into thinking it’s on AC power or it'll never pull more than 500mA) on a split wire usb mini cable for charging at work.
I finally used my brain and checked my chargers. Here's the specs
Standard charger: 850mA
HD multimedia dock: 1.2A

I think the dock is rated higher to power the usb ports. I bet it still only feeds 500 to the phone for charging. Looks like its back to the cable for charging!

Just an update. I think the dock charges as fast as the wall power adapter. Almost certain.

This is interesting as I have issues getting my Atrix to charge in the car dock. I have the ATT boxed car dock with ecomoto dual USB. It simply will not charge in the dock. Connected direct to the car charger and it's super fast to charge. Maybe the ecomoto isn't capable of charging the phone in the car dock.

Is using a different wall charger harmful? I was using my old palm pre wall charger for the first few days and it is rated at 1000mA.

Sorry if this sounds amateur, but I was wondering if I would be able to use my cell phone charger with the Nexus 7 without it causing damage. Or is the reverse true too?
The output on the Nexus 7 charger is : 5V - 2A
The output on the One S charger is: 5V - 1A
The input on the Nexus 7 charger is 100mA higher.
Now technically this means if I use the Cell charger the tablet would take longer to charge right?
But what if I use the tablet charger for my cell phone? Would it damage my phone?
I'm only wondering because I don't want to have too many cables cluttering my workspace.
Thanks in advance.

You're right about the charge time. And yes you can use it on your phone. I have a 2A charger for my g2x that's blazing fast.

It charges super slow on my GNex charger. 10% in an hour
you can use the nexus7 on your phone it will work as a rapid charge, i wouldnt make a habit of it...
Don't quote me on this, but using the 2A charger for your phone should work just fine, as it should have an internal limiter that prevents too much current from being passed through the device, damaging it. I have done that before (with a different charger) with success, so it should be just fine. Also, the N7 *should* charge on the 1A charger, just a LOT slower, and may only charge if you turn it off.
Thanks for all the quick responses guys. I just wanted to make sure I don't do any damage to them.

Mine too, I find it very strange. However, when I use 2amp car charger, then its all good lol. 1.2amp of stock charger must be not good enough
The phone only draws about 800mA maximum, so a 1.2A charger is more than enough, and a 2A charger will make no difference.

Sounds like there might be something wrong with your charger. Try a different charger if you have one.

Well, its not only me, I've seen bunch of people having the same thing. Lots of defective chargers or perhaps custom roms play role in it?
At times when I leave my phone for charging overnight it stops at a particular percentage and starts discharging. In certain cases with the original charger the phone at times continuously flips between charging and discharging.

I had the same problem with mine! Stock charger is GARBAGE! Use something else!
Doesn't anything discharge when no electricity is pumping through the battery? The electricity cuts off when its full. So basically I think the power from the charger bypasses the battery but continues through the phone.
Anybody else seeing that even if your phone is plugged in it will continue discharging if you are using it?
Sent from my HTC One using xda premium
Isn't this always the case? My understanding is that the phone is always powered by the battery and not the plug. If your using the phone and using more power than the charger is supplying then the phone will discharge accordingly. Could be wrong but that's always how I thought it worked.

What's your battery life like? You may have some issues with software maxing out the CPU.
Anyway, the One X battery can run out when using navigation software and on car charger (maybe 0.5A).

I ran into that when I was using a under rated charger or just plugged into a USB port. Official chargers (or equivalent) didn't have that problem it was slower if I was constantly using it while charging, but it did it.
Playing games, navigate, heavy tasks - looses percentage.
Browsing,messaging, mailing,etc - The battery charges.

I believe this is correct. Whenever I used my Lumia 920 for gps+music on a cheap car charger, it would always discharge faster than it would charge. This is because 1) 12V-car/usb chargers charge at a slower rate than AC chargers and 2) some cheaper car chargers output even lower than normal USB charging rates.
Shopping for a new mobile/car charging solution for my Asus TF300T (gonna use for GPS.. tethered to my HTC One) and my HTC One, i ended up getting this multi-use charger. Initially, i was going to get this high power charger just for usb (which is the first charger on amazon i've seen to output 18 W / 3.6 A), but wanted a more unified solution that I could plug both my One and TF300t into. Because I'll be using the tablet for GPS+music, I can tuck the phone away charging at a tolerable rate. Oh, a direct 12v car charger to HTC One will charge the fastest if that's what you're looking for.
i ask because the Galaxy Note II charges really fast with the included 2 Amp charger despite the huge battery. so does it?
It will support 2 amp charger but it will not come with a 2 amp wall charger.
I had read it does come with the so called rapid charge charger, where did you read that it would not?
Anandtech said it came with the same wall charger as the Note 2,which is 2 amp.
"This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging."

Quick charge to my knowledge is strictly for usb charging. Wall charging is unaffected by this tech. 2 amp charger for a phone is damn fast, trust me.

got the i9505 today, it comes with a 2A charger and it definitely charges up rapidly. I used the galaxy app from this forum to check charge current and it is flagged as 1900 mA.

Can confirm it comes with 2amp charger and charges fast (Can only compare it to my S2 but I would say its charges quicker than that). Phone does charge via USB but very slow.
It is realy weird, that it is no possible charging from pc!
SOLVED: It was blocked by Battery Monitor Widget
So does or it doesn't support quick charger the samsung galaxy s4 i9505 android 5.0.1?
