Is there a program/driver that will allow the leo to pull more than 500mA when connected via usb? My TP2 (CDMA) has this installed and its bad ass. I can charge faster off things like a cable box (or my computer) than the wall. It pulls ~928mA.
Right now I have a Y adapter.. I plug the power only usb into the computer and the data into an external source (like a duracell powersource mobile). tBattery reads "AC" for charger input. Then, I unplug from the powersource and plug the data part of the usb Y into the computer, hopefully forcing it to switch to usb mode while retaining high current draw. No dice, its still on AC.. and the data cable is not communicating with the computer/phone. If i were to unplug the power only cable, it would probably switch right over to usb mode and WMDC would pop up and all that. But.. I would be limited to 500mA, which is.. really weak since the phone can only use about 150 of that for charging!
Charge with your phone off may help?
That is not possible, because PC can't give more than 500mA on one USB port.
Check in Windows device manager (PC) and find Generic USB Hub. Then look on "Power" tab.

You can't. You could burn USB port in your computer.

This is a screenshot taken from my touch pro 2.. Plugged into the usb port of my laptop. This is possible. It also is possible with my cable box. It requires a driver/app from nuerom..
http://www.nuerom.com/BlogEngine/po...g-nueBattery2-For-TP2-CDMA-v12-Build-122.aspx
btw.. ports are either in high power or low power.. 500mA should really say 500mA+... Some ports are NOT capable of doing this.. I'd imagine I could trigger the same by connecting devices to all three of my usb ports on my laptop.
many gigabyte mainboards have the function to deliver 3x more power through usb ports. ive tested myself and can only confirm it is charging within 1.5~ 2 hours completely
Yeah - maybe, but if... higher charging amperage causing battery/phone overheating and dramaticly shorting battery life. I know, that dedicated HTC HD2 charger having 5V and 1A (1000 mA), but this is TRAVEL charger and should be used only in this situation by reasons previously wroted by me. I charge my LEO only with PC.
i think it depends on the charger itself. i bought a docking station and while reading the manual i came across a switch that changes the mode between "charge" and "sync"
this lets your device acknowledge that the charger is capable of providing more mA than a normal USB port so that it can draw more power.
The ac charger (or the battery driver itself) is smart enough to trickle down the charge rate as the battery reaches maximum capacity. We have an aluminum battery cover that seems to have a heat pad to transfer that heat from the battery. The battery driver probably has provisions to stop charging if batt temp reaches a certain #.
500mA charge is not enough. The phone itself is able to draw more current than a 500mA line could provide.
I just plugged a y adapter into my laptop. Plugging only the power portion in. tBattery says USB for charger input.. Taking the data/power 'part' of the Y adapter cable and plugging it into a usb power source (with no data pins, like a duracell powersource mobile) puts the phone into ac charger input. I disconnect the duracell charger and leave only the phone plugged into my y adapter to my computer... still says AC charging.
I'm now able to charge the phone using 1 computer usb port. World doesn't end. Phone doesn't explode.
Pictures are worth a thousand convoluted paragraphs.
how can u disable the usb charging? even if its in mass storage mode its keeps on charging.. pls help..
What's wrong with the phone charging?
Isn't it a good thing?
Charge properly
You wouldn’t think that there is a particular technique to plugging your Galaxy S 2 in to charge – and you’d be right. However, you should pay attention to when you charge. If you’re constantly topping up your phone’s battery whenever you get the opportunity, you won’t be doing it any favours.

If i can find the link to a few sites ill post. But lipo batteries LOVE top up charging. Google it. Common knowledge.

Constant charging to 100% is actually bad for the battery, if you stop the charging at 90% your battery will live twice as long, with only a 10% drop in runtime.
I had an Motorola defy, and i am sure you could select not to charge the battery, when connected to your computer.
I'm also interested in the initial question...and my reason: if i connect my s2 with the mass-storage capable usb-port of a Samsung TV for viewing photos directly through the Media Player from the TV, i get an error from it saying too much current on usb because of the charging
so - how to avoid this?
A standard tv usb port does not provide enough power to charge the S2, you need a special adaptor that you plug you S2 charger into to provide extra power, see link below.
New Samsung TV`s don't know when, will provide more power to the usb ports so you will not need the charger in the future.

You guys are thinking of NiMh batteries, not Li+ batteries.
Li+ prefers a full charge, does not have a memory effect. If it stays at low power levels 10% it damages the batteries.
Li+ batteries have around 3000 to 5000 deep charge cycle, a deep charge is when you use to around 10% then charge.
It however has more than 2,000,000 micro charge cycles. Meaning you charge it at around 40%~80%
Battery has a cell life span, which means it is going to break regardless how you use it in 2 yrs time.
As for charging via TV, yes, you need a special cable, but that's for HDMI, not USB. The HDMI port is also the USB port on the phone. Standard USB Port supplies 5V 500mA, however, some Computers and Electrical Appliances with a USB port supply different amounts, depending on design.
Computers can supply 5V 1000mA, TVs might supply 5V but less than 500mA. Media Boxes might supply 5V but less than 500mA. Some USB chargers might supply 5V 1000mA but do not have signal in data+ data- lines, which causes the phone to lag while charging.
WIKIPEDIA KNOWS EVERYTHING. Wiki it, it will tell you it is true.. LOL!
so its oki if you plug the s2 to ur pc anytime and charge it anytime?
Pretty much.
I already got an adapter for connection via hdmi, but i forgot and tried to connect as mass-storage. Thought there might be a trick...
Using a New Trent External charger I noticed that the phone was still losing power, just at a way slower rate than without it charging. Phone showed charging. I was using netflix via 3g at the time. Would this be expected? Not super worried as the battery charges just fine when screen is off and not in use.
How many amp output is that charger??
My phone can't keep up with the charge if I'm veiwing a movie using HDMI unless I run incredible kernel with fastcharge enabled.
7000mAh. Think 1V output?
IIRC, the stock A/C charger is 1 amp.
A lot of aftermarket chargers do not have the balls to charge the Rezound.
you may need to modify a usb cable to short the Data wires to get the full charging potential out of it.
or try one of these cables from amazon:

Does this cable work for sure with the rezound??
I don't need it right now with the incredicontrol running, but I ordered it just as a handy thing to have.
My new Trent works pretty well, but I wouldn't expect it to keep up with streaming vids. I found that it gives a charge to the idle phone at about 800mA, which is about the same as the stock wall charger.
Pick up battery monitor widget and you can track your plus and minus usage pretty well to decide if everything seems OK.

Well, I'll answer my own question. The cable definitely DOES NOT force higher charging at least when using an HDMI adaptor.
If I use Incredikernel with fast charging enabled with Incredicontrol, it will actually GAIN charge while playing a full length movie through HDMI.
This morning, I flashed back to dsb 1.3 with no frills cpu control & hooked up the new cable for charging. I started with a 100% charged battery & after playing a 1 hour DVD RIP from my card, it was down to 89% charged. Using Incredicontrol, during the exact same test the battery still read 100% at the end.
Thanks for your results jmorton10. Good to know. I wonder if it's the connections inside the HDMI adapter messing with it.
Not sure why HTC can't just get this right to always pull the max possible from whatever it's hooked into!

My understanding is because the MHL adapter needs the USB data pins to work properly and they can't be shorted out as mentioned above, the phone thinks it's on a USB connection and limits it's current draw to 500mA.

That is definitely the problem, the battery monitor widget claims it is charging from USB even though it is plugged directly into an A/C charger.
I guess I will be flashing back to Incredikernel/Incredicontrol tonight. I do like dsb kernel slightly better as it never freezes/bootloops etc. ever on that kernel. It does stop responding occasionally on IC (requiring a battery pull) although it doesn't happen very often.
The Rezound complies with the USB charging specification. If your power source isn't compliant, it won't draw more that 500 mA (and probably less if USB doesn't enumerate, but I haven't checked). That's what the "short the USB data pins" thing is all about. Earlier USB charging spec said they should be shorted, the latest says 200 ohms. Any "USB charger" which doesn't do that isn't compliant, and shouldn't be sold as USB-anything, because it doesn't follow the USB spec. Return it to where you got it, and complain (loudly).
Regardless of how much power a charger can deliver, even if it meets spec you won't see more than about 800 mA go into the battery. There's a limit to how much current both the connector and the battery can safely handle, and the phone takes that into consideration.
Remember, the mA reported by utilities is (always?) what's going in/out of the battery. The charger would be delivering more than that (e.g. 800 mA into the battery, plus 400 mA to power a phone doing video streaming, etc.). AIR, the micro USB connector is limited to ~1500 mA, and I've never seen a battery charge at much more than 800, as reported by the kernel. Conversely, when charging from a non-USB charging spec compliant port, the phone won't draw more than ~500 mA from the port, and the battery only gets what's left after subtracting what's needed to run the phone.
Another thing which can affect charging is the cable. If you have a long USB cable using 28 gauge wire, there will be a significant voltage drop across it. USB specs say the voltage should be between 4.75 and 5.25 V, and Android seems to limit the charging current so the incoming voltage stays above 4.75V. Using 24 gauge USB cables, especially with longer lengths, can increase the charging current. Most vendors don't tell you the wire gauge used in their cables, but Monoprice does (no relation, etc.).
I've searched high and low, and can't believe it's not a bigger issue on our device ( and many other deivces).
I have usb 3.0 ports (spec says 900mA max draw). So I should someway be able to achieve these higher rates of charging...
Is the issue the rezound not asking for more from the USB Host? Or is the issue my usb host driver not giving more?
I'm led to believe it's the rezound...
It can't stream 4g, and play full screen video and at least maintain it's charge off of USB.
I really want to resolve this.
The Rezound is a USB 2 device. As such, it can't request more than 5 USB 2.0 unit loads (=500 mA). It will draw more from a proper USB charging port.
Someone in another thread turned me on to this cable:
http://www.amazon.com/gp/product/B003VYBCAY/ref=oh_o00_s00_i02_details
It forces an AC charge on chargers that were showing up as USB (i.e. iphone charger). I imagine it'll do the same thing from any USB port... I believe it shorts the center pins within the cable.
It's sort of an expensive cable... but I plan on getting at least one more. Too many cheap chargers don't give AC, and this phone NEEDS it.
That's not how USB works (if properly implemented). A USB 2.0 port shouldn't deliver more than 100 mA, unless the attached device enumerates (has an actual USB conversation), in which case it may deliver up to 500 mA. The numbers are a bit higher for USB 3.0, but same concept. That cable (which violates USB specs) makes the phone think it's connected to a charging port. It would work fine with a real USB charger (but isn't a good idea, anyway). It will cause the phone to try and draw more than a USB data port can deliver. If used with a USB device which follows the spec, it will be worse than a regular data cable, and the device will only provide 100 mA. Best case, the phone might charge a bit faster than with a regular USB cable, worst case, you screw up the device you're charging from.
Better to just get a proper charger which follows the spec. You can get an OEM 1A charger through Amazon for like $7, cable included. Why screw around with questionable, non-standard stuff?

If this is the case, then I get it.. and I'll ask...
what's taking so long for these devices to be usb 3.0 compliant? it's not like the standard was set yesterday
ah well... another year or three i guess!

It is because they haven't fully utilized the speeds of USB 2.0 by any means what so ever.
That and USB 3.0 is, in fact, fairly new, and with all new technologies it costs money.
Your $300, or $200 depending on when you bought it, phone would probably be an extra $100 - $200 with USB 3.0 technology, which itself is really only like USB 2.0.1 speeds at best.
Sent from the resounding Rezound
USB 2.0 does 480 Mbps "raw," real world, closer to 320Mbps (40 MBps).
That's faster than LTE can provide, and it's faster than a Class 10 SD card, which are the two fastest/most data intensive uses for USB on a phone. There's absolutely no need to add the cost of USB 3.0 to a phone at this time.
Charging when plugged into a PC is a convenience. Use a dedicated USB charger if you want performance. You can get such a charger, either AC or car, for less than $10. There's simply no problem here.
Speed was never what I was interested in, but charging for sure is.
It's convenient, especially when I'm on the go to use my laptop (which has an extended battery) and my phone at the same time (tethering/streaming) and it's nicer if the phone could charge/maintain it's battery level while doing what I need it to do! Even a dedicated charging port on the laptop that can power while the laptop is turned off should be able to give me max charge, so when I plug it in and drive down the road I get a good charge instead of a so so usb charge.
I'm more than willing to pay for this convenience I do carry the wall wart charger in my bag too for those times when I do need a fast charge, but it's silly to me that I need to use two plugs at the coffee shop... I suppose I could also carry an ac plug splitter, but yeah, now i'm just carrying more with me!
Edit: case closed though, now I understand why we can't get max charge from usb 3.0 ports, because it's the device specs that are limited. Stay Calm, carry on, I'll live!
so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

Cool, thanks man, I'm gonna do that.
Why blow data when you can just get a cheap 4$ cable from newegg with 22 awg power leads. I linked it in confirmed usb cable thread. You destroyed a cable and made it special, hence using a special one instead of standard. The base is pre shorted. You increased AWG technically. Get it? You made a charge only cable, when these are special and can be had cheap anywhere. Buy a nice 4$ standard one with the right power lead awg and you can use it for anything.
...or.. Crazy idea here. Get an Android charger?
Cutting up USB cables is a bad idea, especially shorting them out. The data pins are not supposed to be shorted, generally 200Ohms is expected.
They are suppose to be shorted with fast charge... the base normally does this on plug in on AC switch. A USB3 port also does this... all he did was make a charge only cable. With fast charge 2 though, you won't make it much past 1A this way, just like USB3. Why our stock cable has thick power lead AWG and the phone can reach 1.8A.

As I said, 200ohm, not shorted... Anyway.
unless the plugg that u connect the USB cable in i sent chortcircut it won't fast charge whatever cable u use. this is for making a charge cable to use with carcharger ore power packs. of u use a wallcharger it's 99% certain it is already chotend and u don't need this. but if u use the original cable (fastcharge) it won't fast charge in a power pack or car charger.
and I charge att same speed with this cable then original charger cable that came with the phone. measured 1.8a with this cable that's all my Powerpack can output. can probably go higher depending on how mutch the phone can use.
it's li-po so should be able to charge 0-100% in 20min but whill shorten battery life and don't think oer phones can handle it
I fast charge with 3 different cables. Again, it's the AWG. Facts don't lie. My power pack and car charger are pre shorted, so all good. If not pre shorted though, you are correct sir.
my wasn't that's why I made this. so no matter what cable used it won't fast charge. Som people also say u have to by a expensive cable with is bull####
if someone can provide a link with a preshortens cable... well then show it. unable to find any
It is legit. I did this with a car USB cable when I had my One X. It would only charge at USB rate (500ma) even though it was a 1A charger. Using navigation the battery would discharge faster than it charged. Tried various cables, and only got it to work by shorting the data pair. After that it charged AC at full 1A.

Not always. My car cigarette adapter is modded to short data pins. It fast charges all my other devices and even my tablets, but doesn't even charge my G2. It says its charging, no slow charging messages, but still depletes battery. Only way toncharge in my car is to use the second USB port that is unmodded, which slow charges. Annoying.
I still think there is a software bug limiting the charging speeds because you can get different speeds by plugging in the same cable mulitple times.
-sent from my LG G2 using XDA Premium 4
We aren't saying you are wrong, you are just doing something different. It's not about expensive, its about thickness for the combo usb cable. Just the awg. What your solution does is increase awg. They are called charge only cables (pre-post short). What people were searching for are COMBO cables. You are using/doing something different. Why titles are called "working USB" cables, not charge only. We already knew this. There is bugs. That was apparent in the voltage testing. Something in the kernel isn't playing right at all times. I have seen this on my car charger. With no change in conditions, I can sometimes charge 200mA's higher with a replug.

The included home charger for the G2 is rated at 1.8A -- use anything smaller, and you'll see the pop up warning on the phone that charging will be slow and that you should use the "official" charger.
My guess -- if you can find a car charger that actually will put out as much as the phone wants to draw (e.g., 1.8A), and THEN use your shorted data lines, you'll see fast charging of the G2 in your car.

not true have tried 3 other chargers 1.2 1.0 and 0.8 all say fastcharge (ac) with my modes cable. as long as it's over 500ma and with a cable with data pins shortend the slow charge warning is removed an the phone thinks it's charging from ac
charging my phone now with a Powerpack with 1a output and it says fastcharge (ac)
if I use the original cable it goes to slowcharging 500ma iv meshurd befor I put on the shrinking tube for isolation
and a car charger can output in theory 5-20a depending on your fuse in the car
the charging current is controlled by kernels in so phone. my old sensation u culd mod with a fastcharge Kernel so it never limited to 500ma always use max.
Samsung even has the ability to do a full charge in 30min but disabled in Kernel.
lg - g2 uses lipo battery's and culd actually be charged in less then 20min but if we do that u have to replace the battery every 6month at the best.
and lipo are extremely sensitive to over charge and the cells have to be charged with precision balans not to explode or swell.
