I went from an OG droid to the revolution. The car charger i used to use for the moto droid was charging that phone very fast, just like the ac charger. Now with the revo, it's pretty damn slow. I tried shorting the data pins with some solder and the revo actually dropped about 200mv worth of charging current. Strange. I thought shorting the data lines together put the phone into fast charge but when i "cat /proc/kmsg" it says "charging at 0mv" even though it is actually charging at about 400mv as verified by a ammeter. My home charger gets "charging at 1800mv". Some strange stuff. I'm gonna try the ipod method of 2.8/2.0 unless someone else can chime in here. Thanx
I'd be interested in this also. I'm using New Trent USB battery pack and I want it to be acknowledged by the Power Manager as a fast charge source -- not the "computer connected USB" source it shows as now.
I use a store bought adapter, with the verizon/LG cord I got with the phone, and if I use Google Maps and Navigator, I lose power while I am plugged in. Glad to see I am not the only one with the "issue"
I figure its just the way the phone charges, not anything to do with any bugs or what not, so I never really worried about it. I just make sure I am fully charged before I need to use the power sucking apps.

On USB "computer powered" I've found maps and weather apps suck battery much faster than it can recharge. I noticed that the car adapter is detected as "AC Powered" -- even though it's starting off as 12VDC. I was hoping to use the external USB battery pack to keep the internal battery full while using the maps and weather in our boat --- but after 5 hours with screen on and battery pack attached at "USB Computer" recharge rates, the internal battery was flat-out DEAD, and the external pack was only down about 35%.
We just need to figure out what the data lines want to see for a "dedicated charger" type-2 charge connection which will yield the full 1800mv like the ac charger does. I'm working on this...hope i don't fry my phone's usb controller
My problem is, i don't have a charger that shows up as such. My friend's last night did, i may try to get that from him and sniff the connection for resistance values etc.
Hey...I'll leave that level of wizardry to you! Good to know there is a possible answer.

High Speed Charging
Dear All:
I do alternate energy research and we deal with Li battery packs all the time and have seen fires from improper charging. It is okay to advise rom and other software mods but when dealing with electricity it is possibly life threatening. We do not want to read in the next days post about a member dying in his sleep due to a fire. Please use utmost care when you post soldering and wireshorting hacks. We do not know the technical level of the person on the other end.
Second-most, the quality of third party chargers is very shoddy and they do not follow IEC or UL codes which adds another danger factor.
For example I bought a Chinese made Lamptron inverter for my cathode lights and the input wiring was wrong could have fried my gaming rig if I didn't check.
I understand your convern but 1800mA is the charge rate of the wall (ac) charger. That's what we're trying to achieve with a car charger. If you buy crap you're asking for problems. Most car chargers can output 2 full amps @5v but are setup to only charge at 500mA. USB charging of smart devices utilizes the data+ and data- lines as charge mode indicators. Small changes in resistance (therefore voltage) changes how the phone will pull amperage. I think everyone knows the danger of overheating lithium-ion batteries. We're not trying to do anything more than what the wall chargers already do. Check out xda a bit more and you'll see lots of posts about this very subject for different phones. Like this one. Or check out Ladyada's ipod charging research for some other good info. FYI, a good source of CCFL inverter parts is in old broken lcd tvs. Cheap, easy and reliable.
Now that that's out of the way, i set up a breadboard today so i can check some things out but had no time to test so hopefully tomorrow i can give some insight as to what the revo wants data line wise so it goes into "type 2" 1800mA charge mode. Will post with what i find and maybe some pics.
Alright. I just dug in for an hour and found out some things. My wall charger supplies 3.68vdc on both the data+ and data- lines. While using this charger the phone (using /pro/kmsg) goes into "type=2" charging mode with 1800mA. So. I hooked up my car charger. I noticed 2.1vdc on only one data line. So i made a quick resistive divider up to bring both data lines up to 3.68. BAM...didn't work. I also tried shorting the two data lines together while at 3.68v....nope. Then i threw a potentiometer in between the two data lines and tried a few values up to 200ohms....nope. I then pulled all connections to the car chargers data lines and supplied a fresh 3.68v to the output cable...nope. Last thing i did was just use my power supply to supply the 5v and gnd without the car charger in the loop....still couldn't get a type 2 charge. I'm losing my mind here. I think i missed something stupid or am over thinking this. I might start from scratch later but first, i need a few cigarettes. I'm hoping someone can chime in with a simple fix and call me stupid
I found another charger i had bought from radio shack a while ago. It's a PointMobl charger. Plugged it in and got an 1800mA type=2 charge. Sweet. Now i'm gonna dig into it and see why it works....plus i'm ditching the damn spiral cord cuz they piss me off.
I'm using the wall charger from a Moto Razr, and it puts the Revo into fast charge. I found the pinouts here: http://pinouts.ru/all/razrv3_charger_pinout.shtml
Any new insight from that?

Some phones are like that. Common usb is 4 wire, micro usb adds another pin. That pin needs to get a 200ohm resistor jumped to the shorted d+/- lines. The thing is, the wall charger only has 4 pins like every other usb. Unless the cable itself has the extra pin connected to the data lines through a resistor, it still doesn't explain the difference. I haven't taken this other charger apart yet, actually, i don't think i can without destroying it as it looks to be sonic-welded at the seams. What happened to the old screw-ended cig lighter adapters??

Sent from the awesomsness, that is my phone. Rev, Revolt 1.0, swype, go launcher.
deftonesmw,
I wanted to say I'm looking forward to your findings. In the meantime, I ended up buying a car charger that claims high ma charging. It sounds like Danzdroid has issues with his battery pack charger which could possibly benefit from your research too.
Wall charger: 100 to 120 AC converted to low voltage dc
Car: 12v DC no conversion, probably resistance regulated.
Stating the obvious the wall charger is a complete different beast from the low voltage computer/car charger. With out a 12v dc to ac converter I don't think you will ever get a car to charge like a wall charger.
Your radio shack device probably uses some type of capacitor device to ramp up the juice then runs it through some sort of regulator which simulates the AC style charge.
Or at least if I was designing one that is how I would do it.

My car charges like a wall charger. It's not about inverting alternating to direct. It's about getting the phone to pull the amperage. Regardless of what the max current is, the phone has modes of charging. It will pull what it's directed to pull depending on the charge mode it's put into by either d- and d+ voltages and/or resistance across certain conductors. Most car chargers can produce a full 2 amps, that's not saying they are actually doing that though. It all depends on what the phone is taking, not what the charger is giving. You're looking at this the wrong way. 90% of chargers are capable of the output (dc car chargers), it's the phone that desides what to pull according to the chargers instruction (data lines and/or 5th micro pin). The charger's maximum output is equal to the fuseable value it contains. So. Yes, my car charger charges the same as my wall charger. By the way, capacitors by themselves store energy, they don't "ramp" anything. The only caps in my car charger are for smoothing as far as i can see. It's all about resistance, not capacitance. A wall charger is just a car charger with an inverter before it in the sequence. In fact, you could open a wall charger up and split the two circuits, apply 12v to the dc half's input traces and get the same effect....without the ac components even in the same room.
20 buck solution.
Buy inverter.
plug in AV charger.
Enjoy AC charging in your car.
I'm working on a real solution to this but for now an inverter is a good workaround

I went to Radio Shack today and got one of these. It shows up just like the ac charger does. I will be able to use it in my car dock for navigation and not have to worry about the running the battery down. At least that is what I am hoping for.
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.

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

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,

Looking at this one here :

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.

Here goes.....
I've been struggling with charging this phone. I have both the Sprint and the T-Mobile versions and I'm seeing the exact same thing with both. This phone simply won't pull more than roughly 600ma from a charger. With the best of equipment (chargers, cables, clean regulated power, etc etc) a ~600ma (+/- 15ma) is all I ever see at max draw.
I've tried all sorts of chargers including several stock. Same for cables. I know some cables are crappier than others and can restrict current....those that I found did that were tossed in the trash (don't want to keep the fubar cables anyway).
The phones have been in various states of operation too....from one extreme to the other....under heavy benchmark load to "first run" state from a complete reset (full wipe) with airplane mode on.
I said I have a "problem" above. What I mean is that my use-case is such that I use navigation with bluetooth streaming for podcast listening during my commute to and from work everyday. While I'm at work I plug into my TV to playback video podcasts via MHL. At best.....BEST....I can maintain my current state of battery. In other words, if I'm 39%, it'll stay thereabout when I'm plugged into a charger in either case.
No..."Power Saver" doesn't help. What I think would actually help is if power saver had the ability to disable some cores in addition to just governing to 1.1Ghz across all four.
To have a kickass phone that you really honestly can't truly kick ass with feels weird. This thing simply discharges faster than it can charge under any real world load. Maybe my personal use case is unconventional but I feel like it's not THAT unconventional seeing as that the features I use wouldn't be built in if no one ever used them, ya know?
I first noticed this behavior with my previous phone, the EVO 4G LTE. Even though the behavior was there, it wasn't as bad or noticeable due to what I think is the fact it was only dual core...maybe other factors too. But I'm not a developer/engineer so my observations are only from the outside looking in.
I know I can "tweak" my behaviors -- "...do this, or do that. Disable this, or disable that." I understand these things. But having to disable a bunch of things sorta goes against the idea of having this device in the first place.
At the end of day, my observations are my own and I know some are going to suggest I'm "holding it wrong" or whatever, but you guys gotta admit there's something up here with the very limited charge rate.
All that said, I still enjoy the phone. :angel:
PS - I've been using this to monitor current/voltage. The tool has been verified to be working properly by two EE's at my work.

The stock charger. How much does that one show it pulls?
Because I have a 1a charger for my car and I can have the screen on the entire time and it charges, slower, but it charges.

Same same.....doesn't matter the charger capability. Peak draw at any one time seems to be roughly 600ma...+/-. As the charge of the phone gets closer to full, the rate tapers off to roughly 200ma and then to about 80ma as it gets really really close.
I know HTC is trying to protect the battery, but I really get the feeling that this is way over-protective.
I took a picture with my Sprint ONE of my T-Mobile ONE on a 2.1amp wall charger. Notice, at roughly 1/2 charge, it's only pulling about 600ma. Too daggon slow in my opinion.

I assume you mean a 2.1a charger from a Samsung product, that won't work. Samsung uses some signaling on the D+/D- wires to show "This is a Samsung product, charge at 2.1a"
HTC One does not have the ability to offer this signaling and thus will charge at usb rates of 500-600.
Some products short the data wires of the USB to signal that it can supply extra power. This is the type of signaling the HTC One can use. You would need a charger with this capability.
If you don't mind, if you could take a picture of the same setup with the stock charger, that would help.
EDIT: This particular device you've linked seems to block any signaling, according to the reviews on Amazon. I think your problem may lie there.

I understand what you mean. Note that in all my rambling on about various cables and chargers, if I wasn't explicit, I was implicit in that I've tried HTC stock gear too. Same results, no matter.
I do own and did try a few Samsung chargers and cables in addition to the myriad of others. I'm aware of Samsung's irritating attempts to lock people into using their accessories, thus the signaling modifications, but wanted to try them anyway. That's why I used a whole bunch of different chargers and cables. Some are not-so-good and others are great. The one charger I prefer is from VENTEV. It's a dual-port 4.2amp (2.1/per) wallwart.
http://www.amazon.com/Ventev-Wall-Charger-Dual-2-1A/dp/B00BEJSRDI
What I'm saying overall is that the big picture here suggests that we can't pull more than the peak 600ma or so charge rate, no matter what combination of doo-dads you toss at the phone. I'm all in if HTC has some super-secret special vapor rub one can use to charge faster, but even the stock charger they give us in the box which supports 1AMP doesn't deliver that since the phone itself doesn't pull more than what I've seen.
In the attached pics, the one of the charger is the Ventev. The other three show my T-mobile ONE just hit 90% charge and the rate has dipped to about 400ma on average. I took three snaps to show that it does fluctuate a bit. It'll ramp down more at about 95% or so and even more at 99%...................ALL of which is to be expected, I know.
To be clear, at this point, and what you see in these pics, is the stock HTC wall charger that we all get in the box with the phone, the stock HTC microUSB cable, and the measuring tool that is plugged into charger which the cable is then plugged into to then charge the phone. The meter can handle just over 2amps before it pops the internal fuse.

I was directed here from another section of the forum. Have you tried using this?
https://play.google.com/store/apps/details?id=ccc71.bmw
With the stock charger it's telling me that I'm pulling in just under 950mA during peak charging and tapering off as it gets full.
i used a samsung 0,7C charger and it charges at a conntat +800 mah
the HTC chargers also sometime speaks a 900mah + but typically aroung 200 - 700 mah +
it seesm t fluctuate more often than the samsung which fluctuates to a lwoer range when bnearing 100% charge.
Dude, I have the same problem with my EVO LTE, exactly as you describe it, but for some weird reason, my car charger charges my phone normally while other chargers will take several hours to fully charge. I really hope it's a problem with the chargers and not our phones :thumbup: :thumbdown:

Hi. So based on what people have posted, does this mean that there isn't much difference charging it from the wall socket and from a usb port in a computer? Since then charging rate is around 700-600mah and a usb charges at around 500mah

So I download that app, and no matter what I do with my settings, I cannot get my phone to charger faster than about 550mAh. I am currently running at 384MHz CPU, 200MHz GPU, and Force Charge (On/Off), and 50mV undervolt. With the phone just laying there (screen on 65% battery), as I stare it currently saying +529mA (+23.00% /h).
I just tried playing a game, with those same exact settings and it stated charging at +217mah.
