Which chargers work on the touchpad apart from the palm one?
Will the ipad charger work? just plug in a usb to micro usb cable?
Does the touchpad actually charge from a computer USB?
Thanks
My Touchpad charges from a variety of sources, but most will give a warning or not indicate it is charging. My laptop only seems to charge the TP if the TP screen is off and I estimate it would take 10 - 12 hours for a full charge. My Blackberry Playbook charger is close to the spec of the official TP charger and charges in a similar amount of time, but as the voltage is lower I get a warning on the TP screen.

Does your touchpad show the charging icon when you have it plugged into your laptop?

No it doesn't, but if you check the % every so often, it does go up.
To properly charge the TP it requires a power source which will give a minimum of 2Ah charge current. And it has to be specially wired internally to give the correct signals to allow the TP to switch in to being able to draw that current. Failing that charging is very slow at the standard USB rating of 500mAh.
As the TPs battery is 6000mAh max USB charging would take 12hrs.
At 2Ah it takes around 3hrs.
Assuming the device is off.
got it, thanks

Has anyone noticed that phone does not charge while using GPS. The charging indicator is on but when I look at the stats it says discharging at -450 mAh. Is this the way it is and if so, is there a fix? 1 hr 42 m with 73% display on battery use and 43% charge remaining, but was plugged in the entire time while driving under an hour home. I am using the same Motorola high performance charger that every other phone is charged fully even when using GPS.
are you absolutely sure the charger is giving the full 1A?
What sensor app are you using to see the battery discharging?
Mine charges normally with gps on.

I was curious so I tested this with "Battery Monitor" I have it plugged into my laptop currently which only gives +500mA. and not the +1A that you get from a wall/car/high power usb port.
the app is showing +257mA with GPS on and functioning normally.
So charging good here... Might be something with your motorola charger? It could have a sensor in it to detect 'trickle charging mode' that is improperly engaging when connected to the HTC causing the charger to put out a minimal 'sustain only' level of amperage.
good luck!
you need a charger putting out 1A ... most car chargers put out 500mA so find a good one off monoprice
Here's what I'm doing. I have a Belkin 2.1A(2100mAh) USB car charger dongle. The problem is, once i connect the USB cable to it the phone registers it as "Charging USB" and does notcharge anywhere near as fast(power-wise) as if the phone was registering it "Charging AC". I'm not keen on using a power inverter to get the full AC charge so instead i am going to go pick up a cheap micro USB cable, splice it open, then disconnect the data wires(green & white ones) & then tape it back up. By disconnecting the data wires, the phone will no longer think it's a USB connection and then charge via AC, getting the best charge possible.
that should work ^ if thats the problem
I've found that using the included USB cable with a Belkin dual port USB car charger allows the phone to charge as if it were plugged in to a wall. I'm guessing the included cable has a different layout than standard Micro USB cables.

I'm guessing that I have the same belkin dual port (2.1amp and 1amp ports) and the best I've seen out of it is about 250mah charging. This is using the supplied usb/micro hdmi whatever cord for the phone.
I have seen discharge rates off the charger of 750mah which is the highest I've seen on any phone. I'm guessing if you are using the nav on your phone with the screen on, it will probably still be using battery while plugged in.

Possible, but says AC charging in Battery Monitor widget. I will post a few pics.
Here are a few Pics. you can see a couple of things.
-Charger rated at 950 MA out. and no other phone I have owned lost a charge while driving including TBolt, Charge, Bionic.
-Shows as AC charging
- Spikes of good charging detected
Put on Normal power mode today on the way in. live wallpapers did not wrok, just flickered. 3G on vice 4G. Battery still went down, but above 90% on 40 minute drive in. Screen low but on. Bluetooth speaker.
Maybe it is the iBolt car mount. See review online. will try without dock this afternoon on my way home.

Pros: Options for different backs
Cons: Does not charge the phone while it is in use
Try playing pandora when the phone is 100 charged. After 45 minutes on the car mount (and yes it is plugged into a charger and all indicatros show it is charging) and the charge level is 84. Using the same charger but plugged into the phone, playing Pandora for 45 min starting charge level 68. Ending charge level is 100.
Yeah, something is telling that charger to not give you full juice

ok, drove home off the window mount and just on charger, all same except full brightness on screen.40 minute drive. came up 7% battery vice down from 100 to 43%. nedd a few trials to confirm, but looks like window mount is throttleing juice.

i have seen spurts up to 913 with GPS off and screen just turned on. Using battery monitor widget. Not on window mount, just charger.
I can confirm. The car dock will not charge your phone atleast not with the screen on and nothing else running but battery monitor widget.
I bought one and tested it extensively yesterday. I used a Verizon 1a charger and a generic 1a charger. With the dock and both chargerz the phone DIScharged(as in LOST battery power) at between 100ma and 200ma. Without the dock using the same chargers and changing nothing on the phone the phone charged at between 50a and 300ma.
I did the test several times to eliminate any random things the phone may have been doing in the background.
After doing that controlled test I played with it some more and no matter what I did I could not get a positive charge with the dock attached even in airplane mode with the screen backlight at minimum. Without the dock using the same chargers i ran Pandora and a police scanner both outputting through the phone speaker, gps, wifi, mobile all on, and screen on auto and still had a very small positive charge.
Moral of the story DO NOT BUY THIS DOCK unless you dont mind it just being a piece of plastic that holds your phone in place.
I wonder if there's a quick mod to it to get it working right. Like the soldering of the USB chargers I've seen.

I just went ahead and bought an extra battery so I wouldn't have to charge in the car. Only takes 20 seconds to pop in a new battery.
Can charge both batts while I sleep at night.

I was looking for a high current charger for my Android tablet and there was a review that talked about compatibility. Some of the high cap chargers appear to be designed for Apple products and the pin wiring is subtly different. So, on some non-Apple products, the charge is only recognized as a lower power, 500mah charger and the users reported that some devices would normally charge and others would not. Some of the dual port charges also split the power. The 2.1 amp port and the 1 amp port cannot be used at the same time, depending on what is plugged into them. This was also brand specific. I ordered the Amazon Basics 2.1 amp dual charger and will see how that works. I have noticed a difference in charge rates between my Motorola charger left over from the Blackberry and the Verizon OEM one. The VZW one is faster.
I do the same thing I have been doing since my Windows phone days.
I use the AC cord plugged into a 12v to AC adaptor(screen set to 100% bright and no timeout).
I drove 6 hours last week ruuning Google Maps/GPS & my battery was 100% charged when I got to my destination.

I don't know if its a problem in my NT.
It changes only when concocted to the wall charger, not even when it plugged to the PC.
Anyone of you notice this?
TThe NT or the NC comes with a 10 pin charging cable, i was told it has a higher capacity to charge your device. If you don't use that cable, charging will be much slower.
Using the pc will only triggle charge, meaning very slowly, and only with you turn the nt to sleep while plugged in ur pc.
It is just one of the proprietary feature on the nt, sorry.
It does not make any sense.
The NT wall charger is 0.5A. I plugged it to my iPhone charger, which is 1A, with the original cable and it didn't charge.

0.5A must be the input, because the Nook Color/Tablet charger is 1.8A or 1.9A output
You are right. It is 1.9A
My mistake.
a normal micro usb cord cannot "fast charge" so in order for it to work you must trickle charge....plug it into your computer, unmount/eject the device(done on computer) and just turn it off/turn off the screen,
takes about an hour per ~10%.
Yup, its weird. It will say clearly: "not charging" but if you let it sit there plugged into any power source (0.5 amp USB included) and wait for a bit, the battery percentage will go up.
I read an early review, I think on Engadget, and it mentioned this as one of the few negatives of the device. Turns out, it just has a stupid UI.
Well, when you're using it, it isn't charging. There isn't enough juice to charge and run the device so it just runs off the USB power and doesn't use the battery. It needs to be sleeping then it can trickle charge as it uses a lot less power in sleep mode.
I found out today, that if I am booted in Android, the Touchstone WILL charge my Touchpad via my MacBook Pro USB port. The tablet will show the "Home" screen in its "night stand" mode, and I will get a full charge after some time.
If the Touchpad is booted into WebOS, it won't charge when attached to my MacBook Pro USB port, as expected (it's indicated in the product's brochure).
Really odd!
its simple really.
you're a wizard.
WebOS has fail safes in place where it has to be receiving full power to charge the battery to prevent damage to it. Android does not have this. My TP shows charging anytime I connect it in android to transfers files.

The TP will charge from any USB source as long as it is receiving the correct switch signal (actually a voltage) on its data lines.
Currently (pun intended!) only the HP AC barrel charger has the correct switching properties "of the shelf".
There are mods to enable the use of other chargers.
It is this switching signal that allows the TP to charge at full rate (nominally 2Ah). Without it all other chargers operate at much slower and lower charge rates.
It has nothing to do with which OS is in use.
The major difference is the speed of charge and this is governed by the charger (be it AC or car charger) and its rated charging current. If it is too low and the device is in use then the battery will discharge quicker than it can be charged which kind of defeats the object of charging!
The touchstone is more interesting as it can be plugged in to any USB port and operate within the tolerances of its specification and provide an element of inductive charge based on the output of the USB port being used. But once again low current means slow charge.

funny enough it will show you that its charging but most likely its not pulling any power. If you do in terminal cat /sys/power/charger/currentlimit it should show you how much power its actually pulling, and since induction is actually pulling about a 1/4 less power (lost during the induction process) your actually pulling 125mah less aka 375 mah which at that point is useless
The beast? I got mine but haven't powered it up yet for charging purposes. There is no light indicator that tells you when its done.
Got mine yesterday and I charged via AC and it took about 3 hours to complete. After letting it drain over night after 8 hours of heavy usage, I'm charging via USB and it's taking forever. With it on and after 2 hours, it was only at 15%. Now turned it off and it's been 3 hours and it looks like 75%. BTW, press the power button once and the screen will show the batter gauge.
you should charge it while turned on and for 6 hours or more for 4-5 cycles. Let it go down to 5% for those 4-5 cycles. Do not let it turn off from lack of power.
That is from instructions I received from a third party battery which had these detailed instruction to maximize capacity. I am sure you will get 1000 different ways but that is what I use and have always had good battery life.

This thing pretty much requires the cable that came with it to charge at full speed. Older MicroUSB cables charge at a much slower rate and are recognized as USB devices when plugged in. It must be because of the higher capacity battery. When you have the right cable plugged in, though, it charges pretty fast.
I'm noticing that even using the wall charger and the USB cable it came with, it's taking about an hour for the Note to charge only 15%. Anyone else noticing this? Is it normal that the first batch of charges takes this long (at that rate it would take 6+ hours to charge from 0-100%)?
My note charges very fast when I use the ac adapter and super slow when I use the us from my computer. About 1.5 hours on the ac and more than 3 hours on my pc's us
Sent from my SAMSUNG-SGH-I717 using XDA App
Its always a good idea to charge using the AC wall adapter. The USB port on a computer usually supplies ~.5A @ 5v to charge the phone, the included Samsung wall charger supplies double that with 1.0A @ 5v. That is the reason you see such a big difference in your charging times.
(Some computers now supply more than .5A through USB, but .5A is most common)
USB3.0 can supply 5.0v @ 950mA to charge, but the kernel isn't set up to take advantage of this, I'll see if I can change that (it would only affect charging while booted)
Just shy of the AC adapter for those of us with USB3 ports

I was excited reading this because my new laptop has a 3.0 port. However, I then remembered that my power brick for my laptop is kick ass and has a USB port that charges devices at 1A anyways. Haha.

So I got it down to 5% and then I plugged it in at around 8pm and at 11pm it was at 100%. Not bad, not great but seems about right. Now my question is I see a notification that battery is fully charged and to unplug charger but Im going to bed soon and am going to leave it plugged over night. Is this risking the battery in any way?

That would be the only use for my USB3.0 ports so far. Have yet to even need to utilize it.
The charger that comes with the Note can charge the battery in 3hours via ac. I wouldn't suggest to charge via usb, just because it's way too slow. Im using my playbook charger to charge my Note, Galaxy Nexus , and my bb 9900. This charger is 1.8a, it nearly charges 2x faster than the regular 1a that comes with most phones. Same thing for my car charger 2a, i even use my ipad charger to charge my iphone 4s and it's way faster!! Use more powerful chargers... Not more than 2a or your device might melt down!!

That's weird. I was under the impression that GS Note only accepts 1.0A of power. Well at least that's what it saids at the back of the phone. I've got an iPad charger that draws out 2.1A, maybe I should give that a try.
This SIIG INC - SYNC/CHARGING HUB AND READER FOR GALAXY TABLETS - CE-H21112-S1 gives you the capability to charge your Tab through a computer USB port. Seems to work pretty good used it last night. Checked the net prices vary per vendor.
when I plug into the pc usb port even though it shows as not charging after a while the percentage goes up, so it does d a slow charge. Does the hub give a faster charge?
charging via USB is very slow
you can switch it from data mode to charge mode.

charge mode allows a better charge rate.
I'm experiencing a slow charging experience through USB port @ my laptop as well, like at least one of the users mentioned up there... Does this allow fast charging of the battery?
When i want to charge my 7.7 overnightI usually do it thru USB. FYI slow charging is always best for the batteries.
Since i got my 7.7, i have never used the included 2000ma charger. I always use my old GNote's 1000ma charger to prolong the battery life of the 7.7 since it is not easily replaceable.
