I use PDAnet tons of times on my Droid 3, since I moved on to a better phone, I wanted to use it as well. Problem here is, My battery drains fast as hell, Normally I though the port isn't providing enough power to keep up with the draining but I used my desktop which has USB 3.0 and High power ports and still the same issue.
I already experience issues with this phone and planning to get a replacement but I'm just wondering if Anyone else has this issue and will it continue with my new ReZound?
our phone isn't a usb 3.0 device, so it can't take advantage of the extra power.
solution (level: Dealwithit)-- i found turning the screen off at least keeps power use down on the phone enough to keep it level, or gain at least a tiny bit of charge. I use wifi-tether like this, net is 0mA or ~+15mA.
solution (level: Awesome)-- make a hack usb driver for windows that just forces 1A down the pipe rather than waiting for the device to request it

You can shove all you want down the pipe, the phone won't use it unless it's tricked into AC charge mode.

I'll have to confirm, but my belief is the usb host is what dictates how much is ultimately sent... obviously it does this according to the specifications, so presumably the dumb connector just takes whatever it can get... I'd be surprised if a usb device would double check the current it's receiving from a host that has follows the spec... especially when the same port we know can take an AC charge. I have an external portable battery charger, that when it's max, it can deliver the full 1A, but as the external source drops in charge, it delivers less - so it doesn't maul it's own battery, when the external supply starts to deliver less, the phone reports USB charging mode. so I'm wondering if it just reports ac/usb based on how much mA it's getting through the port anyway.

ok so with my gf's nook COLOR it seemed to suffer from the known issue with charging. i.e the "n" symbol will light up but wont actually charge. Does the tablet suffer from the same dilemma? Just wondering because I am debating maybe picking up a nook tablet for her but since she doesn't know anything about this and i dont feel like messing with it so often I figure I'd save myself the headache . Thanks
It's not a bug. You need to use the charger that comes with it or another USB based adapter with a high enough output
You can actually charge the NT with a microUSB cable connected to a computer. I believe as long as you have the screen turned off, the battery will charge. I've charged it with the screen off and with the NT completely powered off.
I forget where I read from but the NT cable has an extra 12 pins which enable fast charging when plugged into the adapter provided. So keep in mind that it will take many more hours to fully charge the NT when connected to the USB port of a computer since the output is much lower than the adapter provided.
the oem charger was used with the NK. I just wanted to know if there were any reports of the NT having the same issue.

There are no reports of the same issue. There are also no custom roms for the NT.
I never experienced the issue with either my NC or NT.
We dont have any custom roms.
So...I get home one morning, I'm sitting at 7%... and I forgot my AC Plug at work. I'm right in the middle of doing a lot of tweaking/benchmarking, basically stuck in 'phone mode'...I plug into my computer and the notorious "You're draining more current than the charger is supplying" hits... So I start searching for some way to increase that. I noticed that my ASROCK motherboard on my home computer had some software that let me increase the charging rate of the USB ports.. it was awesome, because I constantly plug in there and it would barely supply enough juice to keep me hacking away at the phone.
At work on my laptop, I was doing some research.. it appears every major motherboard manufacturer has some type of utility like this! They seem pretty hardware specific, but they seem to support a pretty wide range of their line-up.
Now, I do want to say use this at your own risk because extra power IS extra power. I'm pretty confident that the majority of USB hardware out in the wild right now (as long as you're using at least a half-modern desktop or laptop) is *probably* capable of supplying the current for this, but I just want to put that out there. If you decide to use this (on hardware that is obviously not supported), it's at your own risk. I haven't heard/seen much trouble from it, though... I've been using it for a couple days now and it's a lifesaver at work when I forgot my AC plug. If you have hardware from a given manufacturer, then I'd suggest you use their version (check who makes your mainboard for bigbox laptops/desktops)
Also, Faux's ICS Kernel supports forcing AC charging on any USB plug. I do not recommend doing any data transfer while doing this. I would wouldn't recommend using this on old hardware... actually you'd probably be better off only using it on USB 3.0 ports only, but I've successfully using Force AC charge mode on my laptop with only USB 2.0 ports without issue for a couple months now. You can enable this with a shell script, I personally use a Tasker shortcut with a task set up that does the command [IF %FCSTATE = 0] ( echo 1 > /sys/kernel/fast_charge/force_fast_charge ) checks to make sure it's enabled ( cat /sys/kernel/fast_charge/force_fast_charge ) puts the return into a variable ( %FCSTATE ), makes a sound, then places a permanent notification in the statusbar, and a 3s pop-up that notifies me it's been turned on (with an IF condition verifying that it is indeed turned on, IF %FCSTATE = 1)... second part of teh tasker shortcut is [ ELSE IF %FCSTATE = 1 ] ( echo 0 > /sys/kernel/fast_charge/force_fast_charge ), check to make sure it's disabled ( cat /sys/kernel/fast_charge/force_fast_charge ), put the state into a variable (%FCSTATE), make a different sound, remove the notification, and a pop-up window telling me fast-charge is off. The sound/popup/notification all have IF %FCSTATE = 0.. be ensure that it's off. The cat script places the return value into %FCSTATE. Force AC charging mode is truly useful for pesky car chargers that won't give their full current and are detected as USB instead of AC. There's actually a "safe mode" implemented into Faux's kernel now that will prevent Forced AC charging when there's a USB peripheral detected, which will prevent forced AC charging on on USB 2.0/3.0 ports that are on a computer/laptop etc. This is a good setting if you're only using Forced AC charging for a crappy car charger or some other "dumb" device. You can invoke this mode with [ echo 2 > /sys/kernel/fast_charge/force_fast_charge ]
Be careful with forcing AC charge on older hardware etc, again I don't personally recommend using it on USB 2.0 ports, USB 2.0 is rated to a maximum safe current of a Standard downstream port of 500mA, USB 3.0 is 900mA. This is why you don't want to force fast_charge on a USB 2.0 Standard downstream port. (I do it, but I'm willing to accept the risk... it has worked for me, it might completely ruin your hardware. Use at your own risk) There's also Charging downstream ports, these can handle up to .9A (2.0/3.0) (During high-speed data transfer.), they can provide more than that when there's no data transfer going on, but we don't need much more than that honestly, with no data transfer going on these can provide anywhere from 1A-2A, depeneding on the device. These type of ports are found on desktop computers pretty often. There's also Dedicated Charging Ports, these are the ports you find on wall-plugs, car-chargers, etc. These provide anywhere from 500mA-2A, whatever the actually device is rated. You can find out if the port you're connected to is a Standard downstream port, a Downstream charging port, or a dedicated charging port by calling a read-only sysfs file with this shell command, [ cat /sys/kernel/fast_charge/USB_porttype_detected ], this will return the type of port you're connected to in plain text. Also, there's a TON of variation in actual USB hardware and true capabilities. There's going to be lots of USB 2.0 ports can can easily supply 900mA of current, but there's no way to know for sure until you ruin some hardware. I just want to stress this because I don't want people using this to force AC charging on shoddy USB 2.0 ports and frying their motherboard or whatever. Lots of people using forced AC charging on USB 2.0 ports with great success, just use your judgement.
Here's a list of motherboard manufacturers who offer enhanced charging drivers for their hardware. This is completely different than Forced AC Charging (in Faux's Kernel). Now, I'm not sure if you need to force AC charge with some of these or not.. You probably DO if it's only a USB 2.0 port, because the phone might limit you to 500mA max. I know that with ASROCK's driver/software, I didn't have to force fast charge to see substantial increase in charge current. MSI Advertises on their site that even a USB 2.0 port is capable of up to 1.5A of current with their Super Charger, and other manufacturer's are similar. I wouldn't be too concerned about forcing AC charging if you have hardware that's supported by any of this software. Please check the manufacturer's website, etc.
ASUS AiCharger] (Supposedly only works on APPLE devices, mixed reports. No idea on this one)
MSI Supercharger
Gigabyte ON/OFF Charge
ASRock AppCharger
Biostar Charger Booster
ECS EZ Charger
Foxxconn offers a program called "Smart Charger", but they don't have an advertisement page and it's included with drivers/etc for their motherboards, so I'd check their main site if you have a Foxconn board.
I've personally only used the ASRock AppCharger and ASUS AiCharger.. your mileage may vary, use at your own risk etc etc etc. I've just found this to be immensely useful and I wanted to share. . Some people do report noticeably slower data transfer rates after the installation of these programs (which I would attribute to noise from power on the line, I guess), so keep that in mind. Not everyone experiences this (I sure didn't)
Check it with CurrentWidget, Android Tuner(This is Battery Monitor Widget and System Tuner rolled into 1 app, same people who make both of them), or Battery Monitor Widget... you'll see a huge difference in the amount of current you get from USB (Our Amaze does support current draw reporting, so the number you get from these isn't exactly an estimate. I wouldn't call it super accurate, but it's a pretty good representation of ingoing/outgoing current from the battery. Great for finding out battery drain etc)
Hope you guys get as much use out of these as I do!
Setup the gigabyte on/off charge is installed on my 970 ud3
If I remember right my motherboard has x3 power boost on the usb 2.0 ports and usb 3.0 is already has a higher voltage over 2.0

Does anyone know what might cause this? Is it a problem with my USB port? I noticed it with my home and my work wall chargers.
Before I call Verizon (whom it has been reported is out of Rezounds, and I'm unlocked/rooted), I was hoping for some advice.
Thanks.
An update -- now after I unplug it from an actual PC, sometimes the USB/Charge and USB Debugging symbols remain in the Notifications bar. Could that mean the pins on my actual microUSB port are defective? I've now tested with a 2.1A wall unit too, and every charger I've tried has been a new USB cord.
Oh and just to rule out software I tried in Safe Mode too, no help. Anyone have an idea aside from calling up Verizon (which I will do after my long weekend out of town)?
I've developed the same issue on both of mine I've had. My solution was to simply run a kernel with a Force AC Charge option built in. Have to be careful, however, as the option may cause excessive heating of the battery if you do any intense usage under charging status (playing a game, trying to run GPS navigation, etc.) It rarely poses an issue, but just a heads-up.
You should never use your phone while charging it alwYs turn it off and set it down. When you are charging ylur phone resistors and capacitors are heatingbup your phone now if you are on it talking on it basicly you are heating up the whole board and if it gets hit enough it will losen the solder from the joint and may cause a chip creep effect on the board causi ng varios problems that are very hard to troubleshoot

Try a different USB cable. I've had cables that would charge only, no data. Drove me nuts, I thought it was HTC drivers. Swapped cables fixed it.
The charger is presenting itself in a way that looks like USB. This is very common because iDevices will not charge at all unless the charger does this, so if a manufacturer wants to support iPhones/iPads, they make the charger in this way. Unfortunately, Android devices limit themselves to 500mA when the charger is made like this. Yes, many kernels have fast charge options that make the phone ignore this, but my advice is to get a charger made specifically for Android. Use the one that came in your HTC box as a wall charger if you can. Get the Verizon branded car charger...it charges Android devices correctly.
Yeah, there are many chargers that leave the USB contacts active. Thing is, I've had an HTC branded one that used to show AC at first turn USB on me... Everything else shows USB too unless I force AC in the kernel. Seems like some other condition, degradation or something.
Thanks for the responses so far. I have tried three different wall chargers, each with a different USB cable. Other phones show AC but not mine. At the moment, plugged into the HTC wall wart, I am being asked of I want "charge only" or "disk drive".
Could this be a software related issue? It was mentioned that some ROMS have a force - AC but I am on the newest non Global RUU, unlocked S On, and rooted with TWRP as recovery.
Bump -- is there any chance the RUU and then unlocking and putting TWRP on could cause this issue? Verizon is trying to get me to run a factory reset to "fix it".
Ugh.
I thought I'd throw this out here to whoever is interested in a similar install.
It's been a long while trying to figure out how to get my nexus 10 working otg without draining the battery. So, what I did was eliminate the battery all together and run it with a regulated power supply soldered to the positive and negative pins inside where the battery clip would normally go. Everything ran smooth without any errors whatsoever, then came time to test it all out by plugging the otg cable. what do you know, it worked flawlessly.
I'm able to run a usb hub with 3 flash sticks and 1 ssd hd. Hub must be powered separate with the power plug. This is a perfect setup for my situation since the tablet is installed in my truck and I wasn't too happy with the idea of having a lithium battery inside on hot summer days.
I'm pretty sure this method could even work while keeping the battery installed inside connecting the leads to a double throw relay along with a separate plug that would separate the two power sources.
Testing also passed while plugging it to the pc foe file access and debugging mode.
Hope this helps some people. Don't be shy if you need to ask any questions on this project.
Later
A pc usb port puts out 5v 500ma wich barely keeps the Nexus10 battery level
The ac charger puts out 5v 2amps
I hope your power supply is putting out same amps..

Hello Asylum,
I'm indeed interested in your setup, since OTG+charging is not possible with traditional methods (even pogo cable doesn't work along with OTG).
If I clearly understood, you opened your nexus, removed the battery and directly soldered cables + and - ?
Is it a complex operation ? (in particular to open the nexus and close it without tearing it down).
Do you have a photo of your installation ?
Thank you for your help :cyclops:
LeDuke
I'm also interested in this setup and would love to see pics!
Not to sound like a d1ck or anything, but I have a alternative. Just make a otg cable with a male and female USB ends and just hook up the male end to power lines. Them you can just use a regular USB wallwart to profile power to your drive.
I used this method to run a 1tb external HDD.
Hi all,
My Rezound is having an issue where, no matter the cable or charger, it only says "USB" charging. And on my AC plug it's even giving me the "Charge Only / PC / HTC Sync" menu option as if it thinks there is a data connection on the other end.
This isn't the first time it's happened, but it's the first time out of warranty. USB charging is unbearably slow and doesn't keep up with even basic usage, so I really need to get this fixed or get a new phone (at retail, keeping my VZW unlimited LTE).
Any advice would be welcome. I have a Rezound w/ a damaged screen that I could try to pull a part from if that helps, but I'm not sure if it's just the USB port or something in additional circuitry that I can't access.
For additional information, when it's unplugged it still has the USB charge/pc option.
So when you plug into an outlet it only gives you the usb charging/pc options and doesn't automatically charge from the wall power?
The USB plug in the phone is probably bad, it can't detect an A/C charger is connected so it defaults to USB charging.
You have basically 3 choices here...
1. Get a new phone
2. Get your phone repaired, or fix it yourself. This is NOT easy to do in the Rez as micro soldering is required.
3. Try a kernel with USB Fast Charging and enable it.
This is assuming you have truly tried other cables, chargers, and factory reset.

No, it charges but at 500mA, even on wall power. Sometimes it asks if I want to mount my data, but that seems not to happen often.

Thanks for confirming that #2 is not really an option. Regarding #3, a few questions
1) How do I know if a kernel has "USB Fast charging"? Can you help identify a kernel that has this but retains the 'global' mode capability?
2) If I enable fast charging, does it mean I risk damaging a PC if I plug it into a real USB port that only wants to put out 500mA?

Yeah, nevermind... After doing a little more research into this, I determined this will NOT really do what I thought it would... It could still work, but you would have to modify the kernel settings to allow a high current (800ma-975ma) charge when connected to USB, which would be fine when connected to an A/C charger, but could be very harmful if connected to an actual USB port on a PC. Super Charge and Funky Kernel (both are in the Dev areas here) have this ability, but you make the modifications at the terminal prompt on a rooted phone, not directly in the kernel settings. Essentially you are going to tell the phone to ignore USB standards and charge at 975ma when connected to what it thinks is USB. But like I said, this could be very harmful if it is connected to a "normal" USB port and not an A/C adapter.
Super Charge Kernel (some good into too): http://forum.xda-developers.com/showthread.php?t=1902008
Funky Kernel (Sense): http://forum.xda-developers.com/showthread.php?t=1911297
S-OFF is not required (although it is recommended), but you would need to flash the kernel by booting TWRP via fastboot, NOT flashing and starting from the phone. And the kernel has little to do with the Global mode capabilities of the device, it should be irrelevant as long as the kernel is fairly up to date.
Honestly though, for the price of GSM phones now, I would just ditch the Rez and get something else... I mean you can get a phone for under $30 if you really NEED one (Lumia 520), and a nice Android device for around $100-$150 that will not only give you a new device, but one with tremendously better reception and battery life.
IMPORTANT: Especially with HTC devices, there are THREE different types of kernels for the device, AOSP, CM/CAF, or Sense... You must use the correct one for your ROM or you can soft-brick your phone. For a stock phone, a Sense kernel is required, for other ROMs you will have to look at the ROM's OP and see if it is CM/CAF-based or AOSP-based, and use the appropriate kernel.
