Wall/usb/webtop charging

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

Now that would be interesting. 500,000 volts from a USB. Needs a flux capacitor.

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?

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!

seems like till now there's no way to disable this

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.

Charging question

Does this phone expend more energy to keep up with charging? When mine is charging and I'm using it, it slowly decreases. Is this normal?

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.

So why is it discharging when its being used and plugged in?

Sounds like there might be something wrong with your charger. Try a different charger if you have one.
Sent from my Nexus 4

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 has a similar question about voltages and amperage of chargers and battery degradation posted it here on xda in the nexus 4 forum has to do with this issue of voltages and amps and wireless charging with the official one from google

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.

Fast Charge?

Is there a way to fast charge the Galaxy S4?

I believe that feature needs to be built into the kernel for it to work. The "secure settings" app in the market lists fast charge as a custom rom option, but I could be wrong.

Mine charges at a little over 1% a minute as it is. How fast do you expect it to charge?

That's what I was going to say. I'm amazed at how fast it charges.

Qualcomm has what it calls quickcharge built into their snapdragon chips. The s800 is supposed to charge faster than the s600 too!

I have the original stock charger but I was charging the S4 with my computer and I noticed that the rate was much slower.

Computer chargers are only rated to deliver 500 ma of current while the Samsung charger that comes with the phone will deliver over 2 amps. Basically the wall charger outputs out over 4 times as much power vs. computer usb ports.

My s4 with stock wall charger (2.1a) charges insanely fast. Much more so than my s3.

Charging the galaxy S4 using a powerbank/USB

Is there a way /mod to change the current when charging from a USB/ Powerbank?
I am using a powerbank with 2.1A output but when i use it in my phone i get 500mAh only.
Thanks!

Hi,
Are you sure it's not the cable that is causing the problem? Does the device uses the whole current when charging from the factory wall charger? It's either this or your Powerbank doesn't give you the proper current.

using the cable on a wall chargee gives me 1200mAh average
1900mAh maximum
so i don't think it's an issue.
furthermore, I am able to chage an iPad using the same powerbank and it charges nicely.
i was just thinking i saw something in before where it changes the current from USB.
well thanks anyway. i guess i'll have to replace ny powerbank

Why is my pc charging always "slow"

I have a rooted LG G2 on Sprint (LS980) and anytime I plug it into my laptops USB port (3.0 or other) I get the slow charging symbol. Any ideas to the cause?

Maybe its because your pc isn't capable of the 2000 mAh that the original charger provides, neither 1000 mAh what a normal charger has. My USB hub also gives the slow charging, it just gives around 500 mAh I think, that's why your phone says it's charging slow

Usb 2 is 500mv and USB 3 is 800mv.
I'm mot actually sure where the limit to "slow" charging starts but it is likely around 1000mv

The wall charger adapter that came with my phone showed about 400 mA when charging. This is the same USB that came with my phone too. I've also tried it on my Xbox one and still got less than 15 mA.

That will get rid of the slow charging notification but it won't make it charge faster is it's getting 500mv it will only ever get 500mv.

Usb 2 can only supply 500 mv no amount of tweaking will change that.
Sure you can turn on "fast charge" and it will say it's connected to ac but it will still only charge as much as the thing you are charging it from can supply.

My LG charger gives me around 850mAh but I don't know if it gives more when the battery is nearly empty.

It goes down when the battery is full as you can see here
