slow charge

I too have been troubled with poor battery life and slow charge. Here is what I have experienced:

I charge mine overnight for 9 hours. Every day I take the phone off the charger and I notice it is at 98%. Then I struggle to get through the day.

One day I switched phones in the evening, so the Note was left on the charger for 12 hours. When I took it off next morning, it said 100%. Low and behold... I was left with about 20% more at the end of a typical use day. Does this meen that the 2% extra charge makes that much difference?

I too have tried all of the different high amp chargers with all of the same results.
[AT&T Samsung Galaxy Note I717] dakleenupman:
I guess I was just trying to understand with the OEM charger where the "shorting takes place.
[AT&T Samsung Galaxy Note I717] pj_rage:
I don't have a link to a diagram (you can just Google USB pinout if you want it). I can try to find one later if you still need it. You want the two data lines shorted together. If you cut the cable in half as I did, you only need to short them on the phone side. The other side you can leave open if you want.

But you're absolutely right it would probably be a better idea to short the pins on the charger side. My issue is that my chargers are not easily opened. The cable on the other hand is a quick mod.

If I did it again I would just shave off some insulation from the cable to access the wires without cutting them, leave the power connected, and just cut and short the two data lines on the phone side and tape or heat shrink it up. Fwiw the power lines on my cable were red and black, black being ground, and the data lines were yellow and green. I believe this is standard but I should advise you that it would be prudent to beep it out to the connectors to be certain.

Regarding using an inverter and your home charger in your car, yes this would give you the best charge rate. Supposedly the linked Motorola charger has the pins shorted which would be a less cumbersome setup to provide the same or very similar charging rate. I've ordered one, so I'll report back.

And yeah I'm on AVS as well, same username.
[AT&T Samsung Galaxy Note I717] big samm:
Im using a charger from my playbook 1.8A and my Note charges faster than the one that came with the phone. Matter of fact i bought several of these chargers... I don't know if the pins are shorten but it charges faster. On the box it says rapid charger for blackberry/ playbook micro usb charger.

Sent from my SGH-I717M
[AT&T Samsung Galaxy Note I717] pj_rage:
Yes, the shorting on the OEM charger takes place inside the charger. That's what makes it "special". Shorting in the charger is probably the best option if you have a charger that you can easily open. Or if its a hardwired charger it wouldn't matter if you did it in its cable or in the charger itself.
[AT&T Samsung Galaxy Note I717] dakleenupman:
So theoretically, if I had the shorted cable in conjunction with a 2.1A adapter, that would then double the incoming charge rate from 960mAh to 1920mAh or 1.9A?

,
[AT&T Samsung Galaxy Note I717] LiquidArrogance:
My understanding is the phone will only take what it's programmed to take, which apparently in this case is ~960
[AT&T Samsung Galaxy Note I717] pj_rage:
This. I can't say 100% for sure that 960mA is the limit, buy I really think so. Again, my ipad charger, even with the pins shorted, could not go over 960mA, in fact it was slightly less.
[AT&T Samsung Galaxy Note I717] Mortem Tuam:
Thanks OP, I was wondering why my Note didn't budge on my car charger last night while I was running Google Music and Vlingo. Just ordered the Motorola charger from a previous post. Thanks all!

[AT&T Samsung Galaxy Note I717] LiquidArrogance:
I still have concerns, though. Some people are reporting CHARGING while running GPS + Pandora in the car.

I have the ProClip charger dock which is ~2a and supports "rappid charge" (shorted data pins) yet I drop nearly a percent every three minutes running waze w/o pandora. That won't even last a decent car trip :(

I wonder what the differences are here . . .

Very much thanks to the OP, though . . . very informative post!
[AT&T Samsung Galaxy Note I717] welchertc:
Sounds like Waze is the problem. Looks like it's quite the battery hog. The Infuse actually has similar battery drain issues, but I never saw that drastic of drain using google maps or navigation, even while streaming Pandora. My charge would generally stay locked at whatever % I plugged it in at, neither charging nor draining. You should check how much Waze is stressing your CPU, as well as the % of battery usage it shows in battery statistics. I would imagine it's pretty battery intensive to begin with, even not charging.

Samsung phones are capped at around 1A within their software, and it is quite hard to crack, if it is even possible at all. It was researched extensively on the Infuse forums, as we too had slow charging problems, and it was found out that the Infuse limits itself to taking in 1A, no matter how high the charger output is. Seeing as Samsung seems to limit charging to 1A, the larger they make their batteries, the longer it will take to charge, and it will only be lengthened by the amount that your phone is doing while charging.

That being said, I'm sure Samsung implements it in the software to prevent rapid charging that causes damage to the battery, but they definitely should have allowed at least a little faster charging. I think 2A wouldn't hurt anything other than maybe making your phone a bit warm.

Edit: I confused the two battery threads. ooops.

Great info.

I'm wondering now if the HP touchpad + OEM cable is shorted.

I have a spare HP touchpad charger lying around. Hmmm .. maybe I should try it.

Oh I wish I could charge the note using the HP touchstone!
[AT&T Samsung Galaxy Note I717] dakleenupman:
The wall charger is a 2A which I believe is shorted at the adapter not the cable. I have one too and might try that.
[AT&T Samsung Galaxy Note I717] thinguy:
My Ford Edge has usb ports built into the console. Is there a special cable that can be used for the rapid charge or does it have to be a wall or lighter charger?

Thanks OP for putting the time into this.

Thanks all
[AT&T Samsung Galaxy Note I717] pj_rage:
Other than making one yourself I'm not aware of one. I can't imagine anyone making one because its not really the "right" thing to do -- it really should be shorted at the charger. But no it doesn't need to be a wall or car charger per se. Though I'm not sure if the data lines are ever used on the edge. If they are, using a cable with shorted days could potentially cause a problem. It would depend on what the circuit looks like on their end.

As a side note, I ran Google navigation with the screen on this morning for about an hour using the OEM charger and an inverter in the car. It did not discharge the phone at all and did actually charge it. I was listening to music also, but it was local not streaming. I'll try again while running Pandora also and report back. Then again with the Motorola charger when I receive it.
[AT&T Samsung Galaxy Note I717] dakleenupman:
As an additional note, I tried navigation over Waze with the same battery drain. I figured a house charger on an inverter would work as it should be the full 960mAh you tested.I haven't done that yet but will plan on it. Tomorrow I take back the stuff I bought from Best Buy and locate the Motorola.
[AT&T Samsung Galaxy Note I717] lastdeadmouse:
There is no problem Modding a crazy cheap cable. It's only data pins that you're shorting, so you can't cause any real problems, and add a piece of red electrical tape at each end... bam! A charging cable.

Please let us know your findings. Unfortunately, I can't find time to test.

I work from 8-5pm. By the time I get home my battery is still 20% and I charge it right before I got to bed .. so I can't monitor the charging time from 1% to full.

If you find time, your results would be greatly appreciated. Thanks!
[AT&T Samsung Galaxy Note I717] over2land:

Shorted center Pins...no more charging

Shorted the middle pins on my cheap-o car charger...won't charge at Note at all. I've soldered plenty of times and did a clean job of jumping the two middle pins. Guessing the charger used them somehow or something...not sure. Fuse good...just no charging....Oh well it was worth a try.

Waiting for the stock car dock to get here...
[AT&T Samsung Galaxy Note I717] paleh0rse:
Same here. Charging well.
[AT&T Samsung Galaxy Note I717] techntrek:
Found something interesting. Brought in a cheap charge-only cable, hooked up the Note to my computer at work while streaming XM radio in via 3G, out via bluetooth. After one hour it has gone from 75% to 90%, streaming the whole time.

I have no way to verify right now if the middle pins are shorted on this cable. This computer has USB 2, not 3, so it should be limited to 500 ma per USB port (USB 3 supports 900 ma). So I'm very surprized to see it charging at all while streaming.
[AT&T Samsung Galaxy Note I717] LiquidArrogance:
So long as the screen is not on while it is streaming, then this is not really unexpected. The screen on this device is the real battery hog.

Also, the chances of the data channels being shorted on that cable are close to non existent. If the data channels were shorted then it would not function as a USB cable. Did the computer recognize a device being plugged when you plugged it in? If so, then they are not shorted.
[AT&T Samsung Galaxy Note I717] Arcos904:
Found this carcharger at bestbuy. It should solve the problem of not charging while being used for gps navigation.
[AT&T Samsung Galaxy Note I717] Nucking Futs!:
Purchased 2 of these yesterday since a 3rd party seller on Amazon had it for $5.xx (same price as buying direct from Amazon) BUT they offered free shipping & had a good feedback. Thanks whoever posted this originally!

How much was it? So did it solve the prob?
[AT&T Samsung Galaxy Note I717] techntrek:
My last phone would drain from any charging source while streaming, except its factory 1 amp charger. Definitely from a 1/2 amp USB-A port.

To quote myself: "cheap charge-only cable". ;)

Definitely only 2 wires running from one end to the other, and no device recognized by the computer unlike the factory cable. So it is possible the data pins are shorted on the USB-A end of the cable. I'll confirm tonight with my voltmeter.
[AT&T Samsung Galaxy Note I717] dakleenupman:
Been there done that. No good.... I returned mine.
[AT&T Samsung Galaxy Note I717] dakleenupman:
If its charge only, there probably isn't any data wires.
[AT&T Samsung Galaxy Note I717] bman17:
Has anyone else had the expereince I have had:

I bought the Samsung Car Mount and used it this week for a 6 hr trip for work.

It comes with the standard Samsung charger hard wired into the car adapter (thus can't separate it from itself to use in a computer, etc).

NOw, I had the GPS on using the Navi, streaming Google Music, screen on all the time, volume set at 13 for the Google Music and using the Samsung Voice Talk off and on.

The Car Mount while charging lost charge ever so slightly. In a hours time the phone went from 83% to 72%. Turning Navi & GPS off, screen on, still streaming on Google Music, after an hours time I went from 72% back to 79%. So it was charging, but slowly.

Unfortuneatly, I didn't track simply everything off just straight charging.

My thought is if I should get the Motorola fast charger to replace the Samsung charger the Car Mount came with. Or Should I "accept" that if I have everything on (the only thing I probably didn't have on was the Bluetooth as well!) I will lose charge at the rate of ~10%/hr?

Also, as a side note, I use my Blackberry Wall charger all the time with any of my phones. It's hardwired as well, and from the looks of it, has only 2 wires in it (cable looks like a typical household wire to a lamp with two segmented wires cased together). 700 MA output and it seems to do a full charge in 3-3.5 hours.
[AT&T Samsung Galaxy Note I717] techntrek:
Does EVERYONE here have reading comprehension issues?

To quote myself again: "Definitely only 2 wires running from one end to the other, and no device recognized by the computer unlike the factory cable. So it is possible the data pins are shorted on the USB-A end of the cable."

So you are correct there are NO DATA WIRES, like I said. But there are still PINS on the USB-A plug, so it is possible those pins are shorted within the plug!
[AT&T Samsung Galaxy Note I717] bman17:
I got a chance to look and do a test on the Samsung car mount on the way home.

The charger says 1A output. So it should be good to go.

And in hours time with no use of the phone just straight charging I got a 28% charge increase.

Pretty good I say.

So can the phone suck that much power when you have GPS streaming and screen on going all at the time?
[AT&T Samsung Galaxy Note I717] dakleenupman:

[AT&T Samsung Galaxy Note I717] tbran:
Sure it can. It has been said before that with NAV and screen on, it is little more than a break even proposition from a charging standpoint at 1A. The screen is the most power hungry part of the phone and GPS is right up there in app power consumption.

If you add streaming music to that mix, you are losing charge even while charging.

Thanks to those who provided the test commands and instructions.
[AT&T Samsung Galaxy Note I717] randaddy:
I think I've come across a solution for enabling fast charge by modifying a USB extension cable. This way, no permanent modifications will have to be made to any of your existing chargers/external batteries.

Funny enough the PS vita also has the same issue and is A LOT more locked down than the Note (it won't charge while powered up on anything other than its own proprietary charger, only trickle in standby otherwise) and being the quad core 2200mah battery hogger it already is, I wanted to use my 5000mah external battery to keep it going on long flights. I know there's a proprietary Sony branded external battery on the horizon for the Vita...but why spend more money when I shouldn't have to? So, while searching for a solution to this ridiculous problem I came across an informative blog post.

Link here: http://www.dannychoo.com/post/en/26419/PS+Vita+USB+Mod.html

Instead of using the aforementioned USB angle adapter, I simply dug up an old USB extension cable I had lying around. I cut it to length, reconnected the RED and BLACK power wires and shorted the GREEN and WHITE data cables on the female side (where your micro USB cable would plug into) and voila, I'm now able to charge my Vita with my 5000mah USB external battery (or any other USB charger). No modifications to the Vita or its proprietary cable for warranty purposes.

This same 'adapter' should work for fast charging the Note as well. It was extremely cheap and took about 15 minutes of wire stripping/soldering/heatshrinking. So with this 'adapter' and my 2A iPad charger, I should have no problems charging any of my devices...even the finicky ones!
[AT&T Samsung Galaxy Note I717] pj_rage:
Hey guys, one more update for you. I found a car charger that works great. Charges as fast / equal to the oem charger. When running google navigation and the screen on, it not only did NOT drain the phone, but DID charge it at a rate of approximately 3%/hour. Even with pandora running with google navigation and the screen on, the charge went up, at about 2-2.5%/hour. It charges at the full 1000mA (you can see it bouncing off the limit if checking using the command I posted earlier). Note that this is much better performance than the motorola charger previously linked. That charger causes the phone to discharge even while charging, if using GPS and/or streaming radio.

The charger is this one from amazon: http://www.amazon.com/gp/product/B006SU0SX0/ . It does have two ports, a "2A" one and a "1A" one, which are clearly marked on the charger itself so there is no confusion. The 2A one does NOT have the data lines shorted from the factory, and will not charge your note above the USB charging rate of ~500mA. However, the 1A port DOES have the data lines shorted, and although I did not measure its true max output (to see if it goes beyond 1A), I know that it definitely does put out a full 1A to the note charging circuit and pegs the limit your phone can take for charging the battery. This is the charger I've personally been looking for -- one that allows me to use the phone as a gps in the car on road trips without worrying about the battery.

Another quick way of determining charging source is through Settings->About Phone->Status.
