i recently recieved the touch pro as upgrade from my mogul. to be clear the only internet options i have are dial up or tethering and i prefer the ladder. however im finding i cant stay tethered long without running out of battery. where with the mogul i could tether for 12 hrs straight i cant stay on more than 3hrs. i know its power consumption to charhe and it all runs through the battery. my question is would the cradle with seperate charger and usb plugs do anything? would wifi router software work better than tethering? can i bypass the battery and draw power from the cable itself? any help or tips/suggestions from people with similar situations would be great as i have seached here and ppcgeeks with no luck(thus far,im still looking)
60 views and no ideas? Ouch
when you tether your phone, are you using usb cable to connect the phone to your computer? if so, why not set it to charge the phone while it's connected by usb cable? that way u'll just keep drawing power out of the computer and won't have to worry about phone battery draining quickly
it is set that way. the problem is, with the radio running to stay on the internet and with it sending data through the cable, it seems the load on the phone is too great for the charger to keep up sot aht the battery doesnt die down. And since it seems (correct me if i'm wrong) that the way power flow works is all through the battery (charger -> battery -> device) there is no way that i am aware of to keep a charge on it greater than the power consumption. This is why i was asking of docks such as the expansys one http://www.expansys-usa.com/d.aspx?i=169488 where it has seperate data and power plugs on the bottom would work.
Couple of things to clarify
1. That expansys cradle does have two ports on the bottom, but only one is USB/Power the other is a line out for audio, so that will not help you at all, accept to hold your phone up when you're using it.
2. A wifi router option will consume more power than tethering alone, and in my experience tethering, it does infact keep my battery charged. Are you sure that your usb cable is charging your phone? Do you have the option disabled that allows it to charge whilst connected to a computer?
Thx!

r u at home when you are tethering and do you have Bluetooth on your laptop
the option is checked, as i have double checked since you all have suggested this. yes i have bluetooth on my desktop but i would prefer to stay away fromt that option as its slower than usb tethering. the only thing i think may be effecting me that i just htought of was that i have had the usb cable plugged in the front side not on the direct Mobo connection. i will try this tonight and report back any success
I have the same problem, I've tried using the cable that it came with, the cable that came with my htc-6700, and my girlfriends Blackberry cable. It will usually begin to charge while tethered(PDANet) but quickly will revert to the battery. I'm using my girlfriends laptop as mine has a fried harddrive, her power cable jack is loose as if someone pulled the cord hard to the side, this causes it to switch from external power to battery very quckly sometimes. I thought that this caused the problem I had so I didn't bring it up before. I have my phone set to charge when USB is connected and I do not use any USB hubs. I've tried tethering over Wifi but I don't seem to get as high quality of a connection.(Bittorrent speeds extremely slow, although a speed test showed 2134kbps downspeed) I hope this can provide more information to figureout what is causing it.
Try this! Make sure it isn't causing your phone to get to warm and causing this issue, I had a similar problem with wifi and gps usage hmhm,
Open your keyboard whilst it is tethered and see if that makes any difference, and I'm not sure if it is possible to turn the screen off on the phone while tethered, but if you can do it!
Let us know what happens!

hmm...i wonder what's causing the power consumption to revert to battery source instead of usb cable. have you tried the dongle that came with the device? It supposedly allows you to charge while saving another usb port for headset...etc. Maybe it's possible to charge via wall charger and tether through usb cable at the same time?
or like previously mentioned, charge via usb cable when it's connected to the computer, but tether using bluetooth. I suspect the data tethering through usb is causing the "charge" to drop.
here is what i have found. First the power source must be sufficent ie 1 amp or 1000 ma use an ipod usb charger for moble htc one for home. Second the dongle will only let you charge on the mini port not the e-mini on the side. Problems iam working on is reducing battery drain by shunting off screen but it doesnt work with usb dun. it does work with wmwifirouter but i think there is a heat issue because it stops charging after awhile. Best sessions i have are usb with battery all way charged bthen watch it with battery window open same time.
criddlem,
THanks for doing the footwork on this one.
Shouldn't the bluetooth 2.0 network connection be capable of up to 3Mbit data rates in one direction? I wonder out loud if anyone on this forum has tested connectivity over BT? I don't know how this is handled in the hardware and it could be that the BT only gets a fraction of that in the real world. Of course, the laptop would have to be BT2.0+EDR as well to get that kind of rate in the first place.
Of course, running yet another device at full pace may just drain the battery that much faster!
Have you tested data rates over both BT and USB?
Thanks!
I tether quite frequently using a USB cable as well and I have found my phone always maintains a charging state. It does seem odd that yours isn't. I do know that I am not using the cable that came with the phone............

I was going to suggest something similar.
A couple of years ago I had a sub-notebook that, for lack of a better term, had "sucky" usb ports. When I measured the current supplied was ~100mA. Enough to trickle charge my old TyTN, so it's amber charge light lit up, and I thought all was good.. till it gave me the ugly "Place on charge to prevent data loss message."
Do you have anything there to measure with?

Hi, sorry I may have misunderstood what you are trying to do, but I bought this cradle on ebay http://cgi.ebay.co.uk/HTC-Touch-Pro...photoQQcmdZViewItemQQ_trksidZp1742.m153.l1262
It has a seperate power in line for charging (including a 3 pin UK plug) and a USB sync line in the back of the device.
I belive this device charges from the mains while being connected via USB to the PC. Of course it could be charging through the USB but for me it charges quickly and is connected to PC at the same time so does what I need.
The swivel to use in landscape is an awesome feature too. Battery for me does run down pretty quick, away from cradle, but then I have been used to previous poor battery performance WM devices.
Cheers, Blair
well Erikr88, u said that u have the option check (to allow a charge while connected to your pc) and that u double checked to make sure. well go back and uncheck it as their is no option to check a box and charge while connected to ur pc. the option u can check is to NOT allow a charge, so uncheck it and c if that corrects the problem.
I can't understand why it is so slow to charge!
I tried also nuePower... but with no results.
The phone charge slow (in the same usb port where other htc phones charge quickly!)...
Do you have suggestions?
usb charging is just like that.. if you want it to charge faster, use the wall charger. although, from what i've heard, slow charging is better for the battery anyways.
yes but I usually use my tp as modem and happens that phone discharge quickly than what it charges!!! so after 3 hours phone is completely discharged!!!
This happens only with tp and not with touchHD neither with TytnII!
Incredible!
Although the voltage is the same on a PC USB port as on the wall charger, the amperage is much lower. Thus, the phone will charge significantly faster on the wall charger.
However...
I also use my TP as a modem, and I can leave it on the web indefinitely. If yours is running down, perhaps there's a different issue at play - if you don't have any power hungry apps running in the background you might just have a borked battery or USB port...

Just put your phone off... the charching goes much faster...

I tried just after hard reset without installing any application before.
I'm using Energy ROM and I'm quite sure ROM doesn't have any problem...
I do have the same problem with my Touch Diamond. When connected to my PC or even using my car charger, it will discharge completely after 2 or three hours of using, say, GPS and a few 3G connections to check traffic.
I can't use my Diamond as a modem for the same reason... I have flashed several roms and radios, nothing changed.
Double post
Check if the TP really charges! The unit switches off the charging mode when it gets too hot or better too warm. So e.g. when in use as a GPS in car typically mounted on the windshield, it gets too warm pretty easily as GPS is quite an energy hungry application and quick discharging also heats up the battery.
CU,
Cactus World
P.S. If you are using the TP in car and have aircon, then try to direct one of the cold air streams to the TP to keep it cool. That helps to prevent the switching off of charging mode.
Try tbattery
I use the Energy Rom and it has a utility called tbattery that can show you whether the phone is charging or not and at what rate. Would at least tell you what's happening in the phone. Also gives you the internal temperature of the phone. I've found anything higher than 41 degrees c causes the phone to go into a slower charge mode; it's possible that a higher temp could stop charging altogether - however it should still allow you to power the phone and not use the battery....
I can use phone as modem and still charge it via usb. maybe try a different rom?
I can do that, too ! The problem is the phone charges too slowly, so that the actual power consumption is higher than the charging...
I think that it depends on how you use your phone as an Internet source. I use wmwifirouter, and last time I plugged into ac, my batery still ran down. If your phone lasts 4 hours as a wifi router with no power and charging takes 5 hours, you are operating at a defecit.
I'm using 3G and Internet Connection Sharing through USB cable.
And my diamond charges completely in less than two hours using the wall charger.
Normal behavior, USB port doesn't have enough "juice" to charge it faster.
If you want a quick charge - use wall charger.
1) I can't use tethering through USB if I use the wall charger
2) I use tethering when i'm NOT near a wall power outlet, obviously
3) I don't want a "quick charge"... I just want the phone not to loose charge.
4) I have owned many WinMo devices and this is the first one that will not hold charge while connected to USB
Start -> Settings-> System tab -> Power
There will be a check box that says "When device is turned on, do not charge the battery when connected to the PC." Make sure it isn't checked.
That's the only thing I can think of right now. If I think of anything else, I'll post it.

Thanks for the hint, but it isn't checked.
I think it's just that the phone requires too much power
And it's getting very hot very fast, which will hinder proper charging, too.
I wonder if other modern HTC devices have the same overheating problem...
hello
sorry for pushing up the topic with no sloution but new question, but yesterday i get mad when after two hours of playing streamed music + being connected to wifi my TP battery died :/ Phone was connected to wall charger (oryginal from HTC) and still i was not enough. Damn it didnt happent ever to my blueangel/eten/hermes or any other earlyer device i had. Really im starting to be angry on my latest choice of this phone i should have stay with kaiser
sorry for spelling mistakes but my English is more verbal than writable
well not necessarily,
BUT
the phone has TWO modes of charging.
UBS and AC Charger.
USB recharges about 400-500mah
AC recharges about 900mah
This is flagged by a pin on the USB. BUT this is also flagged in the OS somewhere.
This is done in windows mobile via software hack so the OS thinks it's always on AC charger.
I'm just throwing this out there if someone can figure out what code is flagging the system to think this is UBS or AC connected.
i think the AC method just reduces the charging time, other than increases battery life. Right?

Yep. But I think that's what he's getting at. He wants it to charge just as fast while on usb. There's no way to increase battery life... other than buying a higher capacity battery.

Or using Collins Battery Tweak. http://forum.xda-developers.com/showthread.php?t=791060
you can try that but no matter what yo u cant get anymore power out a USB. if a USB does 4-500 then even if it was hacked it would only output 4-500. If anything it might damage the phone.
Only real possibility I can think of usb charging any faster is if you made a double headed usb cord (for plugging into two usb ports) it won't hurt anything, matter of fact Arduino boards can be used like this as well as external cd/dvd drives without dedicated power, and even some low power routers (like my fon router)
At either rate, even if this were to work, you have to think about how the phone itself rates the incoming power. It may have nothing to do with the actual power charging mode coming into the phone (preferable for dual usb method), but if it has anything to do with just hardware, then it is most probably a no go because of the power balancing in the phone itself.
As far as the pin solution on usb, that may very well help out. I am sure it can range on the incoming power from the plug with that.
If you carefully open a usb charging cable and short the green and white wires on the pc side, with a 200 ohm resistor, the pc will output higher amperage and not let the phone switch into pc charge mode. You will not be able to sync with that cable but it will charge your phone like your ac outlet as long as it is a usb 2.0 port.
Why not just buy a charger for a MOTO Razr? Thats why I use and it charges my phone fairly quickly, but slow enough to put more of a deep charge into the battery.
The less amperage you put towards charging a battery, will actually charge the battery "more".
Hi everyone,
My first post as I haven't been able to find an answer. My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt
Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
Anyone? I still haven't been able to find a solution. I don't see pins touching, but if some pins are touching in the usb port, would that cause the heat issues when I put a battery in that I charged externally? I do get the green led light when I plug the phone in to charge so figure that means the usb is ok?

Yep used the motorola cable that came with the phone (plugged in the wall and just the cable in multiple computers, another motorola house charger (the same as the one that came with the phone), a motorola car charger, and a samsung house charger.
When you say motorola usb service cable, I assume you're not talking about the motorola cable that comes with the phone? What usb service cable are you referring to?

if you buy / make this cable , you will be have posibility to use RDS lite and flesh firmware this also make help (if you have low battery flesh with normal usb cable is not possible )
and second thing... maybe try some car charger ?
hi, since i got the phone (2 month) i was very surprised because the fast charge, 1 game of lol was enough to get 60% or more, but since last 4 or 5 days, i have noticed that it does not longer charge like before, it used to need around 1 and a 20 min to charge all the battery, but now it takes around 2 hours, like using a normal charger. Thanks, and btw english is not my first language :silly:
Happened to me once, rebooted the phone and fast charging was working again.

fastcharge works only with screen off and no app opened (es. game/video/music/etc)
Also make sure you using good quality cable. Some weak ones can "block" quick charge. Best setup is just the stock one.

It still fast charges while in use... just won't be as fast since you're drawing power too. However, using the battery while charging at the same time makes the battery heat up very easily (true for most all devices even on normal 5V/1A chargers) so it is always recommended to keep your device in a state of minimal drain while charging.
I've had issues on past phones where sync/charge cables (stock ones even) get detected as USB connection instead of AC and charge at limited amps because of it. Swapping out to a new stock cable or even a dedicated charge cable with no sync pins usually solves the issue. EDIT: as przemo3679 says below, Qualcomm Quick Charge standard negotiates the higher voltage mode over the data pins, so "charge only" style cords with the data pins missing or shorted will not work in QC mode.

no, the snapdragon 810 has overheating problems so if the screen is on the fastcharge is disabled, is the same reason because while you play and the phone heat up the display brightness cant be over 75%.

It does not disable the fast charge simply because the screen is on. That is how you keep phrasing it.
It disables fast charge if the phone is overheating. Technically this is not the same thing.
Many common usage factors (gaming, heavy mobile data use, high screen brightness, etc.) can make the heat build up fast enough to trigger thermal throttling and disable fast charge of course. But it is also possible to tweak the kernel and thermal files and adjust usage (light browsing only, use strong wifi in lieu of mobile radio, reduce screen brightness) to keep the phone in fast charge even when screen is on.

I disagree. If phone is charging, but not fast it is usually caused by damaged data lanes, or too big resistance on some lane. Cables without sync lanes would work on some devices, but would not on others, current will be limited to 500mA. It's hard to say on which.
And w/o data pins quick charge can't work on any device. Phone use it to communicate with charger to set best voltage and current to actual device.
As i said, original is the best. U can't blame damaged cord for charging issues.
I have a usb voltmeter and I can assure you that it use the 9V charging while the screen is on and also when it's in use (so the screen is on and the phone is in use). The amp only drop when percentage is near complete charging but stay at 9V so technically it still use fast charging.
Quality of the usb cable is very important but quick charge (or fast charge as LG call it) use of higher voltage make the quality less important. I can use a 3 meter usb cable for example, with a iPad charger (5V 2.1A and genuine) I can't even charge my flex 2 (it can't draw more than 300mA and the battery deplete more slowly but don't charge even is not in use). I won't explain why a higher voltage is less sensitive to resistance (the resistance rise with the lenght of the wire) but that's the reason we use high voltage line to transport electricity.
OP here. I use the stock charger and cable that came with the phone, plus they dont see damaged or very used. Still feeling it "slow" :s
I have H950 Stock 5.0.1 , sometimes quick charge doesn't work properly so I turn the power off and charge while off for half an hour it charges very fast and reaches over 70% then turn it back on

I agree with You, in short words more current (A) means more temperature. At the same power (W) bigger voltage (V) means lower current (A). But i think u didn't get what i mean. There is some kind mechanism, which block quick charge when cable is too crapy. I had one of those, and it was fully functional witch data lanes, but it was designed to power 0,5A device. When i tried to connect it to the Flex it said slow charging (or something like that). I think it somehow measures resistance.
I also want to refer to your words: "quick charge (or fast charge as LG call it) use of higher voltage make the quality less important". It is advantage of the quick charge, but not main purpose. U can always made a bit thicker lanes. But you can't change connector. Remember that USB 2.0 standard was designed in april 2000, so it is a bit old now . Back in the days nobody was thinking about 5,5" monsters with 3Ah batteries. Flex is charging with around 15W and it is too much(it can dangerously hot, create arcs etc.). Remember that conductor heats up the most in the greatest resistance point, which is connector. Now we have USB type C, with better connector, which can hold on greater currents, but if we have standard, why did not use it (QC2.0 & QC3.0), and have thinner cord?
About charging time, mine from 0-10% to about 90% takes about an hour.
Guys i solved the problem, after noticing that now the animations (rotation, multitasking, and others) werent working, i decided to do a hard reset, now everything is working, fastcharge, animations, etc. not sure what was the cause, a friend told me was a virus for watching porn lol

I see exactly what message you get, it's the same message when you connect to a computer, right?
It detect a computer and limit itself to 5V and 500mA which was the standard back in the time.
I know someone that fried a laptop motherboard with a vaping bypass, so that limit have purpose.
What is strange is if you get that message with a faulty cable and a lg fast charge charger because the charger should only send signal to negociate quick charge.
I don't think it can measure the resistance or the intensity, or at least the measurement is not monitored in some app because when I use a cable with high resistance and the battery percentage don't go up, I don't have that message.

My bad with translation. If you have no data lanes phone will usually charge with 0.5A as You said, but when i used this crappy one it was something closer to "To maintain best performance use original standardized charger". It was charging faster than 0.5A, but it wasn't QC.

I think you mean the opposite, without the data pin (2 center pin on usb plug) the phone will think he is on a charger and don't limit itself for drawing current even if it's connected to a computer.
Normally a usb device have to be limited to 5V and 500mA,
But qc need the data pin to negotiate the qc voltage so if you use a usb cable without data pin it will stay at 5V.
I have one cable that top at 5V and 100mA (around 80mA normaly) it's very low and it can't charge the phone, it just make it lose battery more slowly, in that case I don't have the message you talk about. That message should appear when it's connected on a computer. My usb voltmeter also have a feature to block data pin, when that feature is activated the message don't pop and it draw more than 500mA from a computer.
There is a good voltmeter on aliexpress, I can make you the link but it's easily recognizable with a transparent blue case, around 10$. There is many model so be sure to take the quick charge compatible. You can make theory on many things but you can truly understand only if you try by yourself.
