Fast charging - how to check? - AT&T Samsung Galaxy Note I717

Hi,
I've recently bought on eBay a bullet-style car charger that claims to give 1-2 amps to two USB ports. I've checked middle pins on both ports - shorted, so it must do a fast mode.
However, with my Note running navigation and media player, I saw it not charging but slowly draining! I used before the charger from my old Dell Streak - it worked fine.
Hard way to check is to solder a converter USB male to female, and measure the current.
Is there an easy way, like opening some engineering menu, and checking the mode (slow/fast) and the current?

This may help.

Thanks, that was very helpful! Saved me trouble with soldering iron.
Although it has a bug and shows amp value 10 times more (like 5000 mA instead of 500), it does the job for me.

Did you find a solution for monitoring fast charging?
Should I only monitor the Voltage and Amps? In case, how must they be??
Ps: so Fast Charging is a matter of having a charger with middle pins shorted??
Tnx.

Yes I did! Sold Samsung and bought the Nexus 5.
On Nexus, the CurrentWidget app just does the job. It never works on Samsungs properly though.

2m USB Cable

Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....
I use the 2m cable that came with my kindle 3 and it works as well as the original one

Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.

Charging speed doesn't depend on the cable but on the charger it is used with.

I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.
If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.
Any ideas as to why this would be?
On a related note, this sounds good, but again the cable looks stupidly short:

What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.
Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.
I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.
Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.
Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
Yep, am using an EP-800.
Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

PowerGen Dual USB 2A Heavy Duty Ouput Car Charger

From the "Ultimate AT&T Galaxy Note Accessory Guide" thread:

$10 -- PowerGen Dual USB 2A Heavy Duty Ouput Car Charger for Apple iPad 2, iPhone 4 4s 3Gs 3G, iPod Touch (USB Cable not included) --- Review
Click to expand...
Click to collapse
Has anyone else used the PowerGen car charger with the Note? I have a handful of other ones that all claim to fast-charge devices, but apparently it only works with iPhones and iPads. But since the PowerGen unit is on the list, can I assume people have used it and confirmed it will give me a 1A charge rate on the Note? I need a charger that can keep up with the Note occasionally drawing 1.4 A or more (display 100% brightness, GPS, LTE, Bluetooth all active, running Navigation).
A quick search for "powergen" in this forum only brings up the above thread.
Works like a champ. My battery was charging at 1600mAh while streaming soundcloud and using navigation. Definitely does the job.
I am using my car charger for galaxy tab 10.1 (2.0 amp) and it is working much better than any of the 1 amp chargers I have tried, OEM, boxwave, etc...
I also use the GT 101. 110V charging brick, so when I travel, only one brick and two cables. My experience is that the 2 amp charger works really well and will charge the phone while using GPS full time, where the OEM charger and other 1 amp chargers either maintain charge, or slightly discharge.
Thanks for the confirmation! Of course, now I discover Amazon won't ship that to Canada, and amazon.ca does not carry it. :crying: I'd go see what TELUS has to offer, but I'm sure it will be A) expensive and B) not have dual USB ports, or perhaps not even a detachable cord.
If you do find one, also buy a charge-only usb cord.

Is that still needed if the charger itself correctly supports fast charging? The cord I use now is the one from my Touchpad. I get 1 A to the Note from the AC plug, and the Touchpad gets around 1.8 A. I do also have a charge-only cable (much thinner cord, only two wires), but it doesn't seem to make a difference.

The cord from the touchpad is probably wired correctly internally for fast charge. I bought a similar dual car charger and did not see a difference with the micro usb sync cable. I only saw a difference with a charge-only micro usb cable. The phone sees what pins are connected and determines if it is going to charge in usb charge mode(<=500ma) or AC charge mode(>=500ma).

So you use the Touchpad USB micro cable to charge your Note in the car? I thought the cable is too short? I am looking for a LONG USB micro cable that is shorted so it will give >500mA.
I am planning to buy the PowerGen but I need recommendation on the CORRECT USB cable that is long enough.

I don't think it is, because it also works as a normal USB data cable. If pins 2 and 3 are shorted (D+ and D-), then the cable become "charge only" and cannot be used for data.

Then it sounds like that car charger was an "iPad-compatible" one, i.e.: it does not have D+/D- shorted out to indicate to non-Apple devices that it is capable of more than 500 mA.

The cable is about a meter in length. I only need about half that to reach from the plug to the phone mount on the dash.

So then how does it charge fast then? If the cable isn't shorted? Motorola does the same thing. IIRC its a shorted setup to allow for fast charging. All of my USB cables come from Samsung, HP, and Motorola and I use them as data cables as well

You short the pins inside the AC adapter or car charger, rather than the cable. If I understand correctly, the danger of using a charge-only cable is if you plug it into an actual USB port that isn't designed to supply more than 500 mA. Your device could then try to pull down, say, 2000 mA and potentially damage the power supply on your laptop or desktop.

I'm using the Rocketfish 3.1A Model# RF-M657D with my Note. While using Google Nav, lowest brightness, keys backlight off, Sync off, HSPA+, the phone still loses charge (albeit, slowly). I'm assuming this is because the charger is not internally shorted between pins two and three as it is marketed as a iPad/iPhone charger. I'm using a Belkin Data/Charge cable so I know that is not shorted.
I have been doing some reading and last night, I purchased the "Satechi Smart Adapter Compatible with Samsung Galaxy S (I can't post links yet, google it.) so I will report back when I receive and pair it with the Rocketfish.
One thing I can't understand is how some of you have reported 1600mA from your car chargers. I am reading that without this adapter/cable mod, the Note will only run 460mA or so. With the adapter/cable mod, the Note's hardware maxes out at 960mA. Also, is their an app that allows me to see how much amperage the Note is receiving or are you guys pulling out the multimeter?

Where/how do you get this info? Asking because I'm curious to see how my car charger does. It has usb ports rated at 2A, and I think it's 2A shared instead of per port, but want to see how it actually does when plugged in.

My rocket fish model must put out more than yours. My pic is above your post. With Google Nav, Google play music (streaming, not native music), full sync, brightness to at least 50% it only lost 4% over 30-40mins.

From what I read, your charger is an .5 amp.
It's not like my phone dies or anything, but it'll lose like 5% an hour and I could be exaggerating. Are you using a charge-only cable or modded cable/charger at all? Like I said, I think this phone is only pulling down 460mA without said mod and I find 1600mA to be incorrect as I read the Note will only pull down 960mA max. We'll see what this adapter does for my charge times.

HTC Car charger 1amp vs generic 2.1amp car charger

When ever I drive, I have my phone hooked up to my Escort Red Line radar detector and my car's stereo via bluetooth (both). In order for me to use the radar detector effective, I need to have GPS and Blueooth enabled. This is a HUGE SUPER OMG battery drainer for my amaze. 20 minutes drive kills about 35% of the phone's power. My radar detector offers a slot to charge my phone BUT it still drains, not enough juice flowing in. Someone said it is because it's probably a .5amp.
So I am running a extension from the 12v lighter that's in the trunk to the front of my car. Amazon has a generic 2.1amp for 3 bucks.
http://www.amazon.com/Premium-Heavy...121&sr=8-1&keywords=htc+amaze+car+charger+amp
But on ebay, I found the original HTC car charger for 15 bucks which is a 1amp.
http://www.ebay.com/itm/HTC-Amaze-4...918506?pt=PDA_Accessories&hash=item27c867022a
What do you guys recommend? My logic says go for the 2.1amp, the phone will draw as much as it needs from it.
The 1amp.
Anything higher you'll damage the phone or the battery.
A wall plug power supply or a usb supply is 5.0v/1amp.
The 2.1 amp is probably 1 amp per port. Although it does not seem to specify.

That means a higher capacity battery (more current NOT MORE VOLTAGE) will damage the phone?!!!!
Totally wrong!
A higher current will not damage the phone. A higher voltage will do it!
Please do not mix the current with voltage!
Voltage is same 5 Volts (±5%) for these “USB like” applications (1A or 2.1A power supply our case )They use USB socket/connector but usually only pin 1 and 4 (+ and-)
Regular computer USB port can supply max 0.5-0.9 A depending on version.
For battery charging devices the current can go to 5A.
Higher voltage will trip a warning window telling you to disconnect and use official HTC equipment.
The phone monitors input voltage to protect the equipment.

and to add to that... unless you take the charger apart and short pins 2 and 3, it will only ever draw 500mA, as it assumes that it is hooked up to a regular powered USB port... I have bought multiple car charger usb adapters, and I have taken all of them apart and soldered the 2nd and 3rd pins together... otherwise charge time = forever, and sometimes it won't even charge if you have wifi or data/gps/bluetooth all going at once...
I recently got an Amaze and am generally happy with it. The biggest problem I have right now is finding the right car charger for it because the car charger I previously used (a 1A monoprice car charger) doesn't give it enough charge. I have been reading through the forums and some has been saying that if the charger is not working properly, it will recognize it as charging via USB rather than AC. In my case, the phone seems to be reading it as charging through AC, but there still doesn't seem to be enough current going through it. The phone will only charge if NOTHING is going on (i.e. screen's off, no GPS, etc.). I've been using CoPilot GPS and it draws the battery like crazy. Anyone has any idea as to which car charger would work properly with the Amaze such that I'll be able to charge (or at least maintain the charge) while using it as a GPS? Do I need to go up to a 2.1A charger?
I would look for a 4-5 star rated 2.1a car charger on Amazon.
Just read through the comments and feedback and you'll find one that's right for you.
I prefer the USB charger base itself and then using the OEM cable that came with the Amaze.
It seems to charge faster with that cable, at least to me anyway.
Remember though if it's rated 2.1a but has two USB slots that 2.1a will be cut in half if used to charge two different devices.
Hope this helps.
I couldve sworn we talked about this months ago. Let me see if I can find the thread.

you won't get the full 2.1a unless you usee a charge only cable or modify the charger as I stated above...
I ended up getting a 2.1A car charger and a USB charge only cable, and it's working perfectly. When I have the screen on full brightness and doing navigation with Co-Pilot GPS, my phone's no longer losing charge and is actually charging. The combo also works with my tablet as well.

This is damn helpful! So THAT is why when driving and using gps or whatnot I would always lose more battery even on charger.. So basically I can just solder the middle 2 pins together to trick it into thinking it is being powered like a home charger? No chance it will hurt anything I assume?

Car chargers work much slower than a wall charger because of the output of it. If you have the screen on, using gps, and listening to music at the same time it won't charge or it will actually drain.

Probably, the car charger is putting out just enough amps to activate charging mode, but not enough to charge with any discernable speed
I would look for a more reputable charger brand. I have found that cheapie chargers just don't perform well. Especially with the 2 amp requirement our devices need. A 1 amp verizon mobile charger with the micro usb factory attached and ment realistically for my wife's s3 1 amp requirement is adequate to provide a stable but long charge time for my note 2. Remember, some power distribution is lost simply in the usb connection between a cheap 1 amp charger and the usb cable plugged into it. Another useful addition for mobile charging would be an ac/dc inverter that allows your factory home 2 amp charger to plug into your vehicle. That would be reasonably clean 110 v ac to dc at 2 amp from your genuine samsung home charger. Better chance of getting the charging capacity you require. Also, don't forget to chech your usb cable. It may look fine, but could be stretched or damaged causing a bad charge connection. But definitely avoid cheap car chargers. Not only can they work sporadically, they may actually damage your phone.

This, I just didn't feel like explaining it all. Also using an inverter can cause problems with strain on the electrical load of the vehicle though. If you have a big truck, they are safe to use. If you have a civic, I wouldn't use one.

I need know the output charger specs. Help

Guys I lost my Gear's charger, not the cradle. Until I buy a original charger I will use a secondary charger. But for this I need to know the output of charger. Please, anyone could help me? REGARDS
Given the Gear S w/ cradle only has 300mah + 300mah battery to charge, any cell phone charger with microUSB will work. Even a PC USB port should work. I didn't even bother take the original AC charger out of the box. Using my alarm clock's USB port for charging every day even when it is totally dead without problem. So, anything with a USB port will work. You don't need to buy the original AC adapter.
Does anyone know how the charging pins on the Gear S are configured?
You guys got a charging cord and adapter?

.....but could you theoretically or actually damage the cradle charger (or less likely i guess, the device itself) if you connected it to a charger with too high an output ?
eg i heard conflicting reports about whether it was safe to use the "wrong" charger for my various MacBooks - these might have anything from 45 - 65 -85w output etc - if i left the proper charger at work could i use any charger lying around at home with the same "magsafe" connecter ?
I was told don't do that versus don't worry the device will only draw the current it needs

No. USB chargers output the same voltage (5V) and varies in current output capability. The adapter won't/can't output more current than the other end (your cradle) requested for. The only time it won't work is if your device need more amperage for charging and the adapter can't supply that much, e.g. a lot of cell phones requires 1000+ ma of amperage for charging but a lot of generic USB chargers can only output 500ma. This results in not able to charge when battery is almost dead.
As mentioned above, the watch has a tiny battery and only requires very little current for charging.
The official AC adapter for watch is labeled 5V 700ma.
Foxbat thx to the answers!

The wall wart for the Gear S says 5vdc at 0.7 amps. I have used other chargers though, computer usb comes to mind, just use a usb to micro usb cable.
I have a meter, and can check the pins for power on the cradle, if that would help.

Looking at the pins with them at the bottom of the cradle, micro USB on the right counting 12345
Pin 1 is +5 volts DC
Pin 4 is Negative ground
Pretty darn sure, measured it about 5 times and every other way possible. Same result every time.
If you were looking at the back of the watch then counting the pads 12345
pad 2 is Negative
Pad 5 is 5 volts DC
edited to add pad configuration

Please post a photo with cradle and the pins order....it's more simple to understand

As this thread helped me when I missed my cradle for charging, I uploaded a photo for clarification.
The pads at the back of the watch are counted 12345 from left to rigth when holding the watch with SAMSUNG bottom side and SIM card slot on top. See attached jpg.
To avoid electrical damage to the watch, I put some transparent tape over the pads first. Then I carefully scratched little holes through the tape for pad 2 and 5.
Then I was able to charge the Gear S just with holding red and black wires from an old cutted USB cable on these pads (black 2 and red 5).
Next step would be to find a clever way for fixing the tiny wires on these micro pad spots while charging.
I tried with a clothespin and it took ages until it finally stayed fixed. Had to take watch out of the wrist band for this.
Fixing with tape didn't work at all.

You guys mention "mini USB" on the charger cable. My Gear Fit2 came with the cradle hard wired and USB plug in. Are there various charge cradle options for the Fit2?
Pins pictures.
Calinormy you saved my gear S thanks.
