I am disappointed to learn the LapDock cannot draw power from the Bionic. Can anyone confirm this? It seems only the converse works: Bionic draws power from LapDock. Thus, if LapDock has no charge and you dock the Bionic that is fully charged, it still will not work. The LapDock will not draw power from the Bionic. The only way it seems to use a LapDock with no charge, even if you have a fully charged Bionic, plug in the wall power adapter into the LapDock. This has really disappointed me and now I regret choosing the Bionic over the Razr Maxx. Can anyone confirm that this is correct: Lapdock cannot draw power from Bionic. If correct, is there anyone workaround? Hell, I'm even open to cracking the LapDock open and doing some modding if that is what it takes. Hopefully, there is a more elegant software hack someone knows of.
Why I desire this? I mostly do most of my work out-of-office in Starbucks, Airports, Hotel Lobby's, etc. Most of these places have enough outlets to charge equipment, but little seating by them. Unless you find a seat by a power outlet that your power cord can reach, you have no way to power your device. And I usually am not lucky enough to get one of these prized seats. Also, spend hours in these places, so my power needs are lengthy. And even with a fully charged Bionic w/extended battery with a fully charged LapDock can give you around 6-8 hours of use, but for one i hate having to charge my LapDock everyday when I get home or remember too. I just want to come home, leave LapDock in bag, dock my Bionic to HD station and desktop setup with it, and be done. Also, even with extended battery and LapDocks built in battery, Verizon LTE is a killer.
Specifically, I intended/assumed I would be able to use the Motorola Bionic Dock Battery Charger (http://www.amazon.com/Motorola-Battery-Rapid-Charger-BIONIC/dp/B005C31FIG) to always have a charged extra battery ready to go and just switch it out with Bionic battery when it drains. So even if I cannot find a seat by a power outlet, I can at least find a open port on a power outlet anywhere in these places and connect the Battery Charger Dock to it. That allows me to sit anywhere and still have a extra battery charging and ready to go. When dies, I just walk over to extra battery being charged and switch it out. Essentially giving me continuous power and no more fighting/hunting for seating. And I'm not to concerned if the Extra Battery and Charging Dock were to be damaged or stolen. I got them cheap and I do not think many people want to steal batteries and charging dock for phone they do not have. It all seemed and ideal remedy but it is all dependent on the Bionic being able to charge the LapDock. Being able to switch out removable batteries and utilize this Battery Charging Dock solution to keep my Lapdock going was whole reason I chose Bionic over Razr Maxx (no removable battery). But again, it seems a dead Lapdock, is useless even with a fully charged Bionic docked to it, unless you plug it in. Any ideas would be greatly appreciated!
Unfortunately the lapdock cannot draw power from the bionic at all. My solution for you would be to find an external charger with the correct plug for the lapdock itself. Failing that, let me be the first to say that i will buy it from you if you are interested in selling it.
Your battery would die very quickly anyway, powering a 10“ LCD, and keyboard with trackpad. Stop being lazy and just charge your lap dock.
Edit - not to mention the Bionic's battery probably doesn't output enough power to run the lapdock...though I haven't checked the ratings.

If Bionic could charge Lapdock:
I think "lazy" is a little harsh and a little ignorant as to my true goal. I believe I was explicit in my post that I always trying to achieve a method to have a continuous loop of power. 1 extra battery charging on the wall, always ready to go when the one I'm using dies. I would argue it is not a matter of laziness but ingenuity. Not only would this achieve an endless supply of power, but it achieves this without having being tied to a charging cable and outlet. It would be the closet thing to wireless charging which is something companies have already began experimenting with. Everything else has gone wireless, why not batteries. It will come, naysayers aside. And their are numerous articles about lack of battery development and improvements happening. Well, for me this above solution was a huge, overlooked, benefit of the LapDock. Show me a laptop where I can easily take my battery out and charge in on the wall across the room. I think many, many people would love a implementation like this. People do not like being tied to cables. Period. And laptop, lapdock, tablet, etc. batteries just do not keep up with heavy usuage and workloads. Yes I could charge the Lapdock at nite. And yes, if you want to play semantics, you can call it lazy. Then along that vein, any more effiecient idea is laziness.
Also, I am not sure i am convinced with arguments Bionic w/Extended battery could not keep Lapdock powered. I am sure it could, the more prudent question is how long? Bionic's extended battery is 2700mah. I read the Motolora Xyboard has a 3960mah battery. That is only a difference of 1260mah. So if Xyboard gets something like around 8hrs on a 3960mah powering it's larger screen, than I could make a somewhat probable expectation that Bionic+Extended Battery could at worse case scenario power LapDock for at least 3-4 hrs. And given that I (and I argue many others who would find this method useful) simply walk over to battery being charged on wall and switch them every 4 hrs or so. Not bad to me. Have a continuos loop of power, not be tied to a charging cable, and all I have to do is switch out batteries every few hours. Has is this that much different from people who carry around an extra laptop battery, or phone battery, or power brick. Also, the Asus Padfone. It is more or less the same concept as the Lapdock. I have not looked into it, but would this be true too for that? Would the tablet not work if you docked the phone inside it, unless the tablet was charged? Or would tablet draw power from it?
My main goal for this post was to see if it was possible and if anyone in community had some ideas as to how. Anything is possible right? Hell, they made Atrix lapdocks work with Bionics, Webtop work without an hd dock, and etc. So maybe this would require a little wiring or something of the sort. Since no solutions were put forth, I will definitely get with some of my engineer freinds and see what they can do. But also, I guess the purpose of this post was also to share and put forth the idea another unique use of this LapDock form factor we have. I think it was genius Motorola did this. I think the form factor, hardware was right on, but it was the anemic WebTop software which killed. Using my phone with Lapdock and HD dock and cloud computing (remote desktop client or Citrix) is the future of smart phones. And i by no means take no credit for this idea. "Nirvana phone" ideas have been around for awhile. These articles and vidoes are what drew me to the Bionic. But one benefit i had hoped for and never expected was to be able to utilize a method of having continous power by switching out batteries with an extra battery being charged on the wall, and not be tied to charging cable. I think it is a great idea, if it were possible. And I would think if some savvy manufacturer implemented this, they would find large consumer base. Hell, i'll throw out another idea. Having a Lapdock like device but inlude a dock on it for an external battery charger for the wall. So you could easily snap off external battery charger and extra battery from Lapdock, plug it in to wall, and comeback to where you are sitting and work. Then when ready to leave, unplug it, and easily snap/dock it to Lapdock and off you go. No more carrying around a big charging cable. All-in-one. Whole thing slides into a 1/2" thick sleeve and off you go.....
I'm talking voltage (and wattage), not mah. The Bionic's battery only outputs a maximum of 3.8v, which is basically the equivalent of 2.5 AA or AAA batteries. I don't know what the voltage rating on the Lapdock's battery is, but I'm guessing it's much higher than that (especially since it uses a 19v 1.85a charger, compared to the 5v 1.0a charger for just about any cell phone), and the Bionic's battery simply can't provide enough power to run it (at least not with the phone running off of it as well).
@brandogg.
Thanks for the info. Never considered that, but i never would have either. Guess that whole idea went to hell. Woulda been nice. Guess that probably hold true for Asus Padfone too. That was gonna be my next purchase. Well, it was just an idea/hope. Still a great phone and moto docks mke it even better especially with Webtop 3.0 coming with ICS.
It's like asking if you can use your phone to jump start a car, since you can use the car to charge the phone.

this has been real hell finding information about whether this http://www.ebay.com/itm/Powerocks-p...y_Chargers&hash=item3cc55ca8b0#ht_4645wt_1163 is compatible with my Motorola defy+ (note custom roms, Switching from time to time, Currently on WIUI ICS) and other information such as how long does it last and etc.
has anybody used this?
is it worth the money and how does it translate to battery % on my defy+.
any other feedback?
and maybe other recommendations (with that price region)
and is there a thing like this that uses AA batteries, if so, how many will it take to charge my Defy+
thanks ahead
EDIT:
what's the proper name for that thingy? because this thing has wayyyy too many names,
power bank, external battery, portable charger, portable battery, extra battery. and many many many more!!! this is why it's complete hell finding information.
what's the real and most proper name for it?
Just a single word 'AVOID'
i don't usually like to be disrespectful, but.
you sir, have convinced me with your long list of arguments and good points of reason to support your advice.
could you please explain, why?
Ok. Here it goes.
I have used these chargers long back, I think around a year back. It barely charges 15% of your mobile battery (I was using a Samsung Galaxy Apollo at that time which had a 1500mah battery) with a single AA cell which I think is totally not worth.
I hope this is enough for you to get a fair idea
so, you're saying that the Portable chargers that use AA batteries are bad, or are you saying all these portable chargers are bad and charge too little?
if you're saying that all the portable chargers are bad and charge too little, then i would have to say that it depends on how much mAh the charger can hold.
say i get the 2600 mAh charger to charge my Defy+ (think around 1700 mAh) when it's completely out, i think that i will charge fully at least once (say around 1000 mAh at MOST! is lost because of the charging procedure)
i'm only talking about the AA battery based chargers. I don't have any idea about other powerpacks as I've never used it.
1 AA battery for 225 mAh!?!?!?!? that's awesome!!! would be great for camping trips, you get like 12 AA batteries (or more, depends on how long you plan to be away from charging your phone normally) and you can even play in the evening or even watch porn if you got Data signal!
i'm still probably going for the normal one, and maybe i'll get an extra charger that uses AA batteries in-case i go camping somewhere.
can people please give feedback on whether it's good enough? why are there only 2 posters?
I think that it works just seen a duracell one in a store near me wich holds 4 AA batts, i think on buying it and fillit with some 4 NiMh AA acumulators rated at 2700 mAh each, just think about it thats 10800 mAh in a portable charge, that will charge my Defy battery at least 5 times even with an extra burning that the charge does.

NiMHs are 1,2V which means, 2700mAh hold 2700mAh * 1,2V= 3,24 Wh which is the same as 11,664 kJ
The Defy battery holds 1500mah at 3,7V --> 5,5 Wh = 19,98 kJ
Taking efficiency in count you might be able to load your Defy with two fully charged NiMHs once, but i`d rather expect that two are not enough.
As for the that eBay-offer: The voltage is given as 5,1V. With 2600mAh that would mean 13,2 Wh. But i rather believe they are stating the capacity at 3,7V for marketing reasons. That would mean 9,62 Wh. That would allow you to recharge about one and a half time.
bump?
So someones after advice on portable power when away from the mains?
Ive been using a New trent imp1000 to keep things going, its a li-ion rechargable powerpack with a capacity of 11000mah and it keeps my Defy going for 4 days.
I also have a total of three batterys for my defy, and a universal li-ion external charger, called a cam caddy, although its designed to charge camera batterys from a 5 volt supply it also quite happily charges up the battery for my defy as well.
So for extreme use i can have a battery in use in my phon, plus a spare with me, and back at base ( or just overnight) a battery on charge in the cam caddy.
If im in an area with access to mains i will take the imp1000 and its charger to top up where and when i can.
I also have a universal USB charger with swapable plugs that fit all major power outlets worldwide.
And to top it all off a USB AA battery charger that will ( slowly) charge up 4 AA batterys form a solar panel, or from a USB input ( faster) , or output 5V through the USB out put port.
This little set up has kept me going for 14 days with no access to mains power ( except for a few bits here and there - 20 minutes at a bus station/railway station and so on) , keeping my phone going (defy) a high powered AA cree LED torch, a camera ( via spare battery+cam caaddy) and an mp3 player. the trick is careful battery management - on the defy turn off everything when not in use, except the ability to receive calls and number your batterys for ID, and the same for cameras etc etc.

i think 11000 mAh is a little too much for me, it may be good for camping trips and etc, but i don't think i'm gonna buy something that (probably) big and (probably) expensive. most of the use of the external charger will be when i'm out with friends for a long time, or say after school i spontaneously decide to go out with friends before getting home (unfortunately a 1 hour drive from friends city to mine) so i need an a portable charger so i won't get bored on the way back, my battery lasts a school day, if i go somewhere that is not home after school, it won't last.
about the extra batteries, are those original from motorola? if not, are they as good as the original? are they worth getting?
The batterys are official motorla ones, as i b ought a cheap un official one and that had issues ( wouldnt show the charge level on the defy )
The battery pack is a "new trent imp1000" which costs £30 from amazon.
I also have a dock for the defy in which my phone usualy sits, at the back of this dock is a slot for an extra battery, left overnight this will charge both my Defy ( with battery inside) and the extra battery in the slot, this is plugged into a dektop pc where some of the USB sockets are still powered up ( giving out 5v) even when the desktpop p.c is off
supdealer offers nice portable power bank
as portable external battery/power bank/portable charger, An ebay seller called supdealer sells a nice one. You can have a look.
It may help you. :laugh:
I have that new Trent battery, its perfect almost same size as defy.

Guys,
If you really want true power on the go, buy a YOOBAO power pack, the 11200 mAh one.
It is really a beast and is really charging a defy several times before going empty.

Yes, all iPhone compatible USB-Chargers are compatible to our Defy and other new mobiles.
Why? EN_62684: Common External Power Supply (EPS)
Why would I use Li-ion instead of AA Cells (NiCd,NiMH or NiZn)?
Higher Energy Density!
Another benefit of Li-ion is the discharging charakteristika (sorry for german captions).
Hi Guys,
Anyone tried Solar Powered Battery Chargers?
Looking at this one here :
source : 6000 mAh Solar Powered Mobile Power Extended Emergency Battery - Obostore
I'm looking fior the same. I bought recantly GOAL ZERO Nomad -7. Instead of charging it drains the power of my Note-2. I guess it is because of the non-standard pin-out (11 pins), so this is the one I would definitely not recommend.

I haven't seen any positive reviews about any solar powered chargers. The problem is that you need to apply voltage (bias it) in order for it to work. Like those solar power panels on the roof of people - if you loose a power to the house, they will not work So they might be draining instead of charging lol!!!
Don't know for sure how it works and if it works and how efficiently. So if anybody has any real life experience, please chime in. Most of the big name external battery vendors don't want to carry this product. I only seen it on ebay and Aliexpress.
I personally haven't tried one. From what I've seen about them, they're very fast, and can be nick-picky about the angle to the sun. On top of it, you'll probably need to check what's the output versus what the phone needs to change.
I think you're probably better off finding some kind of crank mechanism and use that to change the phone. Plus, you'll get a little work out too; you'll live longer to enjoy your phone, 8)
I have a voltaic that I use when camping or on extended hikes. It comes with a 3000mah battery. I haven't used it on the Note2 yet, but used it a lot with my Fascinate. The battery works fine as backup power, though it charges slowly and the phone pretty much has to be off for it to be effective. It takes most of a day of full sun to recharge the contained battery. It's ok if you're going to be away from power for a week, but for less than that I think just an extra battery or two fully charged would work better.
I think we just need to find or build one that supports 2.1 amps (ideally) but anything over 1amp should do something.

I have one I found at Best Buy a couple years ago. It's a single amp box, so charges my Note II very slowly. I've used it on my bike when I'm out on rides. I have a mount for it and my phone. While riding, I use bluetooth headphones. It does work, but like someone else said, there needs to be one with 2.1 amps.
I as well have a Nomad 7, but mine charges my note without issue, although I will admit, it is impractically slow.
I bought this couple of months ago, charging the phone is a wii bit slow but it works like a champ!

I wouldn't mind if the solar power was a "backup" to a regular external battery, but if all it did was solar I wouldn't be interested.

WICKED... just stumbled across this on ebay. If you are a roll your own DIY type and want to charge a rapid charge device like Note2 or a tablet or something, this might be a great thing to look at.
http://www.ebay.com/itm/DC-DC-5V-36...018?pt=LH_DefaultDomain_0&hash=item2c700c47c2
I, personally, don't like the mini-usb connector... seems kind of goofy. I'd prefer just two wire terminals to connect solar panels to.
But yeah, if you've got high voltage solar setup... e.g. anything between 5V and 36V and want to have a clean, regulated 5V usb compliant output, this would likely be your guy. I'd also want to make sure it really does work with note2 - in terms of negotiation of currents higher than 100ma. YMMV FWIW
AND if you don't need note2/tablet 2A...
this guy seems like about the right fit.

Lapdock+Wii == Gametrix
So I have a spare Nintendo Wii and a lapdock (hopefully pick some more up if there are still any at Radioshack) and I am going to disassemble the Wii, reconfigure it to fit on the back "panel" of the Lapdock, and get the needed cords to create a Gametrix[/]
My initial goal is to connect a Nintendo Wii to my Atrix Lapdock by... (with modifications)
1) a. Having the Lapdock’s Male Mini-HDMI plugged into a Female Mini-HDMI TO M / F Fullsized-HDMI converter. Thus allowing a direct HDMI connection from there.
This takes care of ½ of connections for both the Lapdock and the Wii.
2) a. Ideally I am looking to hook the Wii’s power supply directly to the Lapdock’s Male Micro-USB port, via a Female Micro-USB TO M / F Fullsized-USB. From there I’d need a USB to Female Wall Outlet (3 prong?) this would entail finding(unlikely...) / building one.
This takes care of power needs, (if it works) leaving only the unlikely usability of the Lapdocks built in keyboard and mouse / USB ports.
2) b. if number 2 section a (above) doesn’t work because of lack of volts traveling through the USB to the Wii, then I’d be left with connecting an external battery to the Wii and just taking advantage of the screen.
Hopefully if I have to result to section b then I’d at least be able to use the keyboard and mouse?
I will update with a Diagram of my plan “a” and “b” tomorrow after school.
Here are average power draw for the Wii. @17 Watts http://www.blogcdn.com/www.joystiq.com/media/2007/02/next-gen_console_power_lg.jpg
And here for Gamecube. @23 Watts http://www.tpcdb.com/product.php?id=1615
Lapdock voltage output. ??? I think I'd have to replace the battery because it's only supposed to charge a phone/run an OS...
Lapdock insternal battery mAh ???
Please guys I know it's a lot but any input is great input
sounds fun. good luck dude.
Use a wii its better and supports a HDMI converter.
The gamecube already has a battery pack accessory and a screen accessory so its easy been done
Sent from Moto Atrix 4g on Neutrino 2.91
I have decided to go with the Wii, I am trying to find info on how many amps the Wii draws and if the Lapdock is capable of powering it...
I think I would try seeing how they both look on the screen before diving in much further, but it does sound like it could be a fun project.
Other thoughts:
how useful the project will be specifically to you? For many of us, due to the limited availability of the lapdocks, there's a limited number of people that will be able to try this themselves.
do you plan on strictly playing games, or are you going a bit further by using Linux on the device? I imagine there is a way you could use the keyboard as some type of input device, although you may have to create some translator device from a programmable Microcontroller.
is the screen big enough for enjoying using the device or is it more of a challenge than it's worth. The screen may be plenty big enough for a handheld device, but for something like using a Wii controller where you are at a distance from the screen, is it big enough?
Budget This is something we all overlook far to often. Something starts off small and simple, but before you know it, you end up spending way more than you had anticipated.
I have 2 Wii's and a Lapdock, so budget is covered.
I'm not going to use the motion bar, just gamecube games.
My main concern is if the Lapdock can power it.

Power will probably be an issue through USB as USB does have a specification for max current of 500–900 mA (general); 5 A (charging devices). After that the port should shutdown to prevent burning out the controller.
Edit: I was looking at your figures above, did some digging, and I think you have a couple hurdles.
To start with, for power consumption, you want to look more at peak then you do at min and give yourself a bit of cushion, mainly because running at max power all the time will tax components. Second, and this is a big one, the Wii power pack apparently is 12V 3.7A (44.4W). USB is only 5 volts, and at 900mA you're peaking at 4.5W. However, if you could somehow manage to trick it into charge mode, you might be able to squeeze 25W. That's if it works like a standard USB port. If you can do that, you can step up the voltage with a charge pump, but I'm not quite sure how close to max that will put you due to efficiency losses. You may be able to go the other way and use the Wii to power the lapdock, or you may have to power them independently.
All that said, I think it's still important to just try to see what it looks like on the screen before digging in too far.
I plan on charging it through the Micro USB which you said supplies up to 23W+ Which is apparently plenty for the Wii. I'm going to order the necessary cords to attempt this, this weekend. So next week I'll know how much, if any, I have to modify to power it.....
I'll continue to research, and thanks for your help!
EDIT: screen size isn't an issue, as I'm have it right in from of me like a laptop, Playing Super Smash Bros Melee and the like.
BIG Message to everyone who's reading this. THIS IS MY FIRST HARDWARE MOD (as if that wasn't obvious?)
Anyways I'm gonna pick up a soldering iron as well, because I'm not finding a way to charge the Wii (assuming the Lapdock is capable...) There are no real ways to convert the micro usb to the 3 prong standard outlet that the Wii uses... So I may need to make my own? Will this work? http://www.sybausa.com/productInfo.php?iid=1274 Although I can't find where to buy it.

You mean you want to convert 5V DC to 120V AC and then downconvert to 12V? Better to just go from 5V to 12V, but the reality is that it's much easier to go down than up. What does the lapdock itself have for a power supply?
Edit: Looks like the Wii has some type of USB keyboard support. Not sure if you want to try getting that to work, but it might come in handy.
I know but isn't the Wii's power cord a standard 120v 3 prong wall charger? I'd have to convert the 3 prong format to a Micro USB.
The lapdocks power supply is the battery if that's what you were asking...
Thanks for helping on my first project btw.

I know but isn't the Wii's power cord a standard 120v 3 prong wall charger? I'd have to convert the 3 prong format to a Micro USB.
The lapdocks power supply is the battery if that's what you were asking...
Thanks for helping on my first project btw.

I'm glad to share my limited knowledge. Anyway, Really, I'm unsure if you can pull 25W out of the USB or not, but even if you could, you'd lose a good chunk of that in going from 5V to 125V AC, because at this point, a charge pump is no longer an option but instead you would need a power inverter, and since most of the commercially available ones are designed to go from 12V DC to 120V AC, you would likely end up building one yourself. The charge pump (buck–boost converter) is much easier to build, but I'm not sure about how much power you can get out of it.
Here's one I built from modifying a schematic I found online somewhere:
I hate to be the party pooper here, but I think no USB port will ever be able to deliver that much power. We're talking about several ampers here. Neither the USB port nor a great majority of USB cords are built to withstand that. Most USB hardware is designed to carry at most 1A. And then, even if you manage to get sufficient power flowing and power the contraption up, I wouldn't expect too much autonomy out of it since it is after all battery-powered. I would expect a lot of heat from the batteries too.

Battery Charging Specification 1.2:[14] Released in December 2010.
Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A.
But as I said, I don't know if you can get that much power out of this particular device. 20W @12V is 1.6A, but in order to power that from 5V, you would need at least 4 Amps, which puts it close to max, but not over it. The actual port connector is rated much higher than that.
Edit: I do have to agree on one point though, running on battery power will be pretty limiting, especially when you consider what the batteries were intended for in the first place.
So you're saying that there's basically no way to power the Wii with the Lapdock's setup? Ughhh I assumed this would be a major issue but decided I'd leave the verdict to those more knowledgeable than myself... So you're sure there's no way? Well anyways I hope at the very least to connect an external Battery (recommendations?) and hopefully get the Wii to recognize the trackpad and keyboard esp. for linux use... I'll keep researching and keep you guys posted.

Didn't read your reply Lehjr before posting mine, sorry about that. Anyways I'm still confused about whether or not the Lapdock is capable of powering the Wii? Anyways here is where I'm getting my very limited information on basic electronics. http://science.howstuffworks.com/environmental/energy/question501.htm I will keep studying though don't worry:laugh:

Hm, interesting. I don't know, I'd say even if the USB hardware might be able to withhold such high currents, it's only for a short while, not for continuous use. I'm talking about all the USB hardware now, not just the plugs and cords.
Anyway, while 5A might indeed be the theoretical maximum, I have yet to see an USB device that actually delivers anywhere close to that. Even most commercial "high-speed" chargers deliver only up to about 2A.

Right, running that close to maximum is likely going to be short lived, and that's if it can be coaxed to go there in the first place. I'm not sure what the portability thing is about anyway. The Wii may be small, but it's heavy.

Possibly capable, very slim chance, but doing so would be running very close to max the entire time the Wii is powered. You would also have to build a device to convert 5V to 12V, again, not impossible, but you do lose some power do to conversion inefficiencies. Is there any particular reason you want the device to be portable? IMHO, in order to run the Wii for any length of time, you would need a decent set of batteries. A few amps plugged in is one thing, on battery power that's something else. I could easily see you using something like a couple Power Wheels 6V batteries and a 12V charger or some similar setup, maybe some lithium cells if you're a big spender. Anything more than that and you're wheeling this thing around on a cart with a deep cycle marine/RV battery.
Haha a definitive answer would be welcomed as to whether it's theoretically capable or not, but if you can't provide that, I completely understand! Anyways It just needs to be temporarily portable, like 1 hour battery life is plenty. Thanks... Btw I can't actually thank you guys anymore as I'm out of thanks.
Got it from eBay.
Charges faster in phone...while using!
If battery is around 40% it being be charged overnight.
Anyone else experience this?
could be the amp? maybe below 1 amp? Samsung charger has 2amps om it. check your charger and look for the amp. btw. the lower the amp the better for your battery..
Buy an OEM charger. The Samsung one is $50 from Samsung website but you can get the Asus charger from Google play store for $25. Both are two ampbi believe. Or you can get the 1a for $25 from samsung. Getting OEM directly from an OEM or authorized reseller or a storefront lime Google is key. Getting cheap chargers is gonna bite you in the ass one day or think about it like this. Why keep wasting time buying cheap chargers again and again when you can put up proper money and get quality in one go and have peace of mind for a few years. I even stopped buying chargers from amazon because they're just cheap knockoffs too. Phi hong makes good chargers and power supplies but they are harder to source. Phi hong came with my nexus one andy galaxy nexus OEM Home dock.
Anyways, aside from that part of the reason for slow charging is you probably have an unsafe charger that is not rated what it really is and is made of poor materials. Getting a quality 1a or higher, preferably 2a in this case and your gnote2 should charge @ 1.8a. In other words, you can charge from zero to full in ~2-2.5 hours. Or from partially full to 100% in less than 2 easily.

Unless I am mistaken, OP is referring to battery chargers, not usb chargers. That's how I charge mine, too. I have spare batteries, and they all get charged directly. When my battery is low, I just swap. I hate having my phone attached to a cord, even at night.
Yes, all the battery chargers I've had for every device (including this one) have been lower amp than the usb chargers supplied with the phone. It is especially slow for this huge battery for the Note 2. While it bothers me in concept, it's never actually been an issue for me, so I haven't done anything about it. I don't know if higher amp battery chargers are available, but I don't feel like spending extra money on one.
As far as battery health goes, charging at a lower amperage certainly isn't hurting the battery. If anything, it's actually better for it.
Yes...charging just the battery with wall charger.
@ 40% it will not be charged at 6am when I wake!!!
Are there better wall chargers?
Why do you hate having your phone attached to a Cord overnight. I heard that's fine and do it every night.!

Not for the phone, for me. It just bothers me having a wireless device locked to a wall. There's no reason for it. And I frequently get up in the night for various reasons (kids, work, insomnia, etc), and it bugs me unplugging in the middle of a charge cycle.
Incidentally, a non-removable battery was a deal breaker, and one of the reasons I didn't get a Nexus 4. I got used to never plugging in my last phone, and I don't want to go back. It was torture the first week or two with the N2 before my spare batteries arrived.
The charger should have its output printed on it, I've had a look at the pics on ebay and the first two I found that I could read were 500mA and 350mA, the original charger is 2A or 2000mA. Samsung make there own battery charger http://www.samsung.com/au/consumer/...es/EB-H1J9VNEGSTD?subsubtype=other-multimedia the output is 1.7A so much closer to the original usb charger.
I'd be worried about my back cover getting loose doing what you do. I had three batteries for my old phone, but I did not swap them on a daily basis, just when travelling or away from power for an extended time. I've ordered some wireless chargers so I can have one by my bed and another downstairs. I know they only output 500mA too, but for an overnight charge thats fine for me. I dont think there is any issue with interrupting the charge cycle, the two main enemies of lithium batteries are heat and being totally/almost discharged on a regular basis. Its best to keep them topped up.

It looks like the OEM battery charger is available on ebay for around $15. That's good to know in case mine ever crap out on me. These cheapies that I get tend to.
As far as the back cover getting loose, after 3 months, it is a little bit looser than when it was new. 1.5 years with my G2x didn't loosen it at all, but the build quality on that thing was fantastic. I keep this in a case anyway, so it being a little looser goes unnoticed. If it gets bad, back cover replacements are cheap.
If one of the devs can make the kernel capable of fastcharge, it would not take but half the time to charge. Yank who is working with Faux on his kernel, helped make the kernel fast charge capable.

But what is the point of having it charge fast, when all it is is going to drain faster?
I charge mine overnight with a charger rated at 750mah I believe and it last me a whole day. As oppose to using a 2.1 am charger I have, where the battery percentage would start dropping by the first hour.
Correct me if I am wrong here, but this is what I've notice with my last few phones.
The Perseus kernel with stweaks has the ability to change the charging parameters.
With it overclocked/undervolted I am getting better life than I did on stock.
Not for sure what you mean as it depleting the charge faster on a higher amperage charger. Kind of sounds like you may have had failing batteries, etc.
There seem to be a few misunderstandings here regarding batteries and chargers.
1) The charge rate, when the battery is in the phone, is controlled BY the phone. The charger itself just supplies regulated power to the phone. How much current is put into the battery at any given time is up to the phone, which is why kernels can do things like fast charge, it's controlled by the kernel. Now, the reason the battery charges faster when using the stock charger vs. something lower current or a computer is simple. The phone can detect what it's connected to within some limitations. It sounds like our phone can also sense the incoming voltage levels and back off if the supply becomes unstable.
2) Using the stock 2A charger is "harder" on the battery than a lower current charger. Not true, at least not within any margin of error you will be able to detect without specialized equipment. Lipo batteries are generally built to charge/discharge at 1C. C in this case stands for capacity. So our 3100mah batteries can charge at 3.1Amp and be within safety margin. So the 2Amp charger the phone comes with is perfectly fine for the battery. Without seeing a datasheet for the battery from Samsung, that's a good guess. And again, the phone controls the charge current based on a number of parameters. You could connect the phone to a 5V supply capable of 100Amp and it will still only use what it needs.
3) The percentage readout on the phone screen is a GUESS. Don't pay it too much attention. For this same reason, evaluating 3rd party batteries based on phone runtime etc is not useful. To validate the battery capacity with any accuracy requires a test setup discharging the battery through a known load and measuring how long it takes to get to a cutoff voltage. I've done some of these tests myself on stock and 3rd party batteries. In general, the OEM batteries are always at or above spec, the 3rd party battery manufacturers lie. Often by upward of 20%. Even the high $ batteries. Keep that in mind when shopping if you want extras or extended batteries.
4) Interrupting the charge cycle is bad. Nope. It's fine. On this same line of thought, full cycles ARE bad. Don't do it. Don't think too much about it either though. Just plug it in when convenient. Or set it on the wireless charger if you've installed one. Generally speaking, they actually don't like to be charged to 100% either. Keeping it at 20%-80% is actually best for the longevity of the battery cell itself. In practice, you will probably have a new phone before any of this is actually noticeable.
The OP sounds like they are talking about a stand-alone charger, where the battery is not in the phone. Those will vary wildly in quality and capability, particularly from ebay. They are probably cheap POS devices. Not that that's really a bad thing, just know about it. It's probably a very low charge rate device, perhaps even down to 100ma or so. That would take forever to charge our larger batteries. As for if there is a better one, probably. If Samsung makes one, it will probably charge faster than the phone with the provided charger plug as there would be no load from the phone using power. Of course, it will cost a lot more as well. Look for devices that at least claim they will charge at 2Amp or so. In practice, they will probably be a lot lower, but your chances are improved. Not many people will break out an ammeter and check, after all.

Perseus kernal has fast charging settings.
What ttabbal wrote is mostly correct. But the problem lies within some input voltage protection logic tied to the charger chip of the phone which is extremely (and too much so) sensitive.

Can people stop calling it fast-charge, it's an idiotic term which technically means nothing. While most kernels have some sort of charging speed configuration options, they're all useless in regard to this problem as the current in the end is decided by a different logic. You'll have to disable unstable power detection and that's the only way to make it work and fix the problem, unless you go hunting down high quality cables and chargers.
Personally I also encountered the problem as my stock S3 charger, as many others here have reported, has deteriorated and it would only charge at an effective 300mA. I disabled unstable power detection and now it charges at the full given current limits, without any issues.

It would be nice. I have an N7 but haven't bought a charging pad yet because I didn't feel I'd get enough use from it. My N7 battery easily lasts me a full day and I just throw it on the charger at night. No big deal.
I use a Moto X right now and tether my N7 to it on my daily bus commute (~2 hours each day) and I usually need to give the battery some juice before I leave work to have enough for tether on the ride home and the remainder of the evening.
When I get the Turbo, it will easily last a full day. I don't think I'd ever really need the full two days of battery life, but it would be great for long days. My Moto X right now can't make it through an entire day with my usage. I know I'm probably above the bar in SoT (usually 3.5-4h), but I average about 13h, according to GSAM over the last 8 months. Could use a nice big battery to keep me going for 18-20 hours.
I guess it does have wireless charging...
The new DROID comes with a turbo charging feature so when you’re low on battery, a 15 minute charge can get you up to 8 hours of use. DROID Turbo comes with the Motorola turbo power charger in the box at no additional cost. And for added convenience, the new DROID is wireless charging capable.

Awesome..thanks for that
Semi-related.. Can anyone suggest a nice charging pad? I've looked at them for my N7 before and the prices seem to range pretty widely. I understand they charge pretty slowly.. but are they all the same for speed? Does the device need to be perfectly aligned in order to charge? Can I charge two devices at once (N7 and Turbo)?
I'm thinking I'll throw a pad on my desk and one at home, either in the living room (coffee table/end table) or bedside table.
There are some features of a phone that you appreciate more when you have them than you do when you read about them. An example might be high speed charging, their are a few technologies out there for this but the bottom line is when you have it you really come to like it. Its very nice when you have forgotten to charge your phone and you suddenly decide to go out to be able to get a charge on it that will see you through in the time it takes for a quick shower. When it was new and I first read about this it sounded good but no big deal, I usually make it through the day fine and charge over night. Now that I've had it though I really like it.
This is kind of a long way to get around to it but wireless charging is the same way. Its very nice to simply have the pad on the night stand or wherever you may put it and drop your phone on it without having to plug it in. It seems like nothing much but once you get used to it having to plug in seems like a bit of a hoop jump. One benefit of wireless charging that often gets missed is port damage, I have had more than one phone in the household that met its demise by tweaking the micro usb slot so that it either wouldn't charge or couldn't transfer data or both. My understanding is we will still have to plug in to get high speed charging but the ability to do both if we want is a very good thing in my mind.

Good points. I held off on a pad for my N7 because the battery easily lasts me through the day, two if needed (I usually charge it every night, though). Even though the Turbo probably wouldn't need to be topped off during the day like my Moto X would benefit from, it would be nice to have the option. I agree on the Turbo charger too. Great in a pinch if you are at an airport or something and just need some quick juice for a flight or something.
3.9Ah batt's gonna take a long time to charge with a 700mA limit though.
Should be OK overnight. Then again if it's only discharged to 60% when you start it shouldn't be hateful.
Yeah, wireless charging works best where/when you are going to set it down for a while such as over night or when you place the charger where you set your phone in the evening. I used both, one on the nightstand and one on the end table by my chair. In the latter case it is quite convenient since you can answer a text or what have you and simply set it right back down and its charging again. This is why I think its a great feature to have both wireless and high speed by whatever name, they should complement each other well. I say should because I've had both but not on the same phone, I'm really fairly stoked about this handset for this and other reasons.
