Keep tablet charged while connected to pc - Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting

For development I have a 12.2 connected to my pc via usb. I would like to keep it charged while it is connected. As it is now the tablet will slowly drain. If I don't charge it up fully before I start development I might have to switch to wireless adb when the battery is dead, which is a lot slower. Can I somehow charge the tablet while I have it connected to my pc? Maybe something like a Y-usb cable so I can charge it and have it connected to a pc at the same time.

i haven't tried it, but you could probably make a special cable. cut the power and ground lines in the cable and route them to an adapter. So basically, the data lines are connected to the PC and the power lines are connected a wall adapater.
Get advice from someone that knows more about USB pin-outs before trying it though. There may be other web forums that could give specific advice or directions to do this.

Hi, You don't have the box ticked in the battery screen do you ?
the one that says
When device is turned on, do not charge the battery when connected to the PC
this should be unticked.

Hi Dean
Now I dont have it ticked !!
Any other idea's?
The problem could also be your usb line or usb port. try some alternatives first.
Tried everything, different usb leads, different sockets even different laptops !!
Help
Same problem here. But i changed the USB cable and problem solved. Did u tried it, with the official USB cable from HTC? (I guess so, just to check)
Yep I did !!
Will try again when I get home though..
Thats strange... my TP came with UK power adapter, so I couldnt use AC power until I get an adapter (4 days)... in these days I always charged via USB (all night long)
Well I tried the official usb lead and it charged last night, Im now using the official lead again using same laptop and same usb port and guess what !!! It wont charge again
Have I a faulty touch pro?
shall i phone vodaphone and ask for a replacement

Hi,
this is sounding kinda weird..
What kind of wall charger came with the phone, mine is a wall adapter that i plug the USB lead into to charge the phone
So i know my USB lead works as this charges the phone with both the adapter and via USB on any PC ( i have tried home and work PC's)
Sounds like it could be a handset issue then ???
mine is a Vodafone handset that i bought unlocked and flashed with a different ROM and its working fine..

Laptops can be a bit funny about USB charging, I remember one laptop I had wouldn't charge my phone (SE K800i at the time), unless it was on mains power. The laptop had to be powered up while on the mains, with no USB devices plugged in, then it would supply power to the ports.
My work laptop is also a bit funny about it, I had to disable powering down of the USB ports otherwise it won't power them back up, but since if nothing is connected there's not much of a problem. There is also the possibility it's powering the port, which will charge the phone, but not enough power to actually make it worthwhile, you can check to see how much power is going to the ports by looking under device manager. So you might want to check it's not a problem with your laptop.

This is exactly what mine turned out to be. At work I've got a Dell Optiplex 745 tower and none of the USB ports put out enough power to charge my phone and have the phone on. I've got wifi turned off but the data, EDGE, is always on. If the display is on and I'm in Storage mode there's very little charging going on. It doesn't drain quickly but it definitely isn't going up. If I'm in sync mode it drains pretty quickly and it seems as tho it's not even charging at all.
What I do now is plug it in at work and turn off the display. Kinda sucks but I need my phone fully charged at all times.
I have the same problem....
the usb and the factory usb are different if u have looked carefully
firstable, the shape of the heads are different. secondly, there are 4 pins inside usb and 6 pins inside the factory usb...I guess that's the problem.
Try messing with the USB to PC settings. I know my TP was acting funny and not charging, and after i disabled network functionality, i think it started charging. GL.
Thamks for all the replys, if done everytjhing sometimes it will charge sometimes it wont, I have it connected to my laptop all day for internet sharing, it has charged up very slowly twive, and not at all 8 or 9 times, same usb slot , laptop plugged into mains, official usb lead used ( it never charges from another usb lead )
This is the 3rd htc Ive owned and the first to play up like this over usb !!

Have you tried it plugged into a desktop computer? It would rule out the laptop being the problem if it didn't work. You could also use a mini-usb cable, which could also prove if the official cable is a problem.
Having similar problem...
I'm having a similar problem. My laptop used to charge Touch Pro when i connect it. Now for reason i noticed that it doesn't anymore.
I could be wrong, but I thought I read in the manual that when the phone is synched to a PC, it only charges in trickle mode, so it doesn't recharge the battery efficiently. Is this the problem?
same problem here. Mine was working fine with ANY charger whether it be USB, car charger or wall charger. But now it will only charge with the htc plug but not the HTC wall charger. The plug is the one with the ports for tv-out, headphones.
I'm going to go try and do a hard reset.I dont understand what could cause this.

Touch Pro and tethering woes(battery)

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!
Kewlj1313
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.

Does anyone have this Charging problem?

I just noticed something with my phone. When I am charging my phone it takes a really long long longggggg time to charge. Usually more than 8 hours. I kept tracking the charge and usually it remains on 99% forever. Sometimes if I get a call, or open the phone to check how much battery life was charged or just anything that makes the phone active a minute later its finished the charge. I think my charging is messed up and my phone will remain on 99% unless I make it active so it registers it as complete charge. Is there a setting or something that I am missing?
bump .
Is 99%-100% a big issue? The 8 hour charge sounds too long, but is that from the mains charger or from a usb charge?
Does the phone actually charge correctly & just not show the battery status properly? (charge it on the mains for 2 hours, then use the phone - if it lasts the day then its probably just the indication playing about).
Were you charging from the main USB port on your computer OR via the USB hub. there is a huge difference.
If you were charging through the USB port from your computer, you would be getting power exclusively for the phone
if you were charging through the USB hub, then your phone is fighting for power with other devices so therefore less power going to charge it.
your other choice is get yourself a cradle so you can mainline from a power outlet and also from the computer directly.
Goodluck

A self-powered (not bus-powered) USB hub would be able to deliver the same 500ma/port that the controller on the motherboard would deliver. In reality, most USB ports (both on motherboards and hubs) can deliver more than that, because there's a lot of poorly designed USB devices that'll draw more.
true. I did forget to mention self powered ports, just because I rarely have those kind of hubs. Godefroi is right. If your USB hub is powered via an adapter, then that should not be a problem, otherwise it can be either the cable or even the port itself.
Fuze - power outlet wont charge
I am getting really annoyed by this, someone please HELP!!! I have a Fuze and for some reason for the past few weeks my phone will not charge on a power outlet but it will charge on a usb and with the car charger. I have tried my dads charger same thing so i know its not my charger...

[Q] Can't charge off PC USB?

My Photon Q won't charge off a PC USB port, or my laptop. Is this common? Thanks.
Are you using the usb cable that came with the phone? Reason I ask....I've discovered this phone is extremely picky about the cables you use. So far of the ones I have on hand, I can only consistently charge while in the car using my Belkin usb charging adapter with the Motorola cable that came with the phone. That includes a fairly nice ferrite core 6ft usb cable I got from Monoprice...which it works fine at home on AC, but in the car it stutters back and forth between charging and not charging.
Just today I used a cheap USB cable I bought off of ebay to charge my PQ using my laptop.
Its one of the ones sold as "HTC OEM USB Charger + cable" on ebay for like 3 bucks.
I also charge it at home using a green 3m cable from ebay, also bought for like 3 bucks lol.
Does it require that drivers be installed on the PC to get a charge? I've tried a few cables that I have laying around. I'll see if I can find other cables to try. The weird thing is if the phone is off, and plugged in, the LED lights up green, as if it's charging. But using the same cable, if the phone is on, it won't acknowledge that it is plugged in.

No, I wouldn't think so...
I've been able to charge off of many different USB cables on my Q. Not sure... Only thing it's been picky on so far is the wall wart - cable it hasn't seemed too picky about.
If its an old desktop with USB 1.1 it may not charge, and many laptops won't allow charging via USB if the laptop itself is not plugged into AC. Just a thought.

Very good point ^^^. I've heard some laptops, even when plugged in, still don't provide enough juice to charge (some) devices. Perhaps your laptop is one of these low-power USB port devices.
ive noticed that this phone is picky about what charger you use. i have a hard time charging on my pc as well. and certain micro usb's i have dont seem to charge it well either. needs to be the stock plug it came with.
I've basically given up at this point. Blackberry AC chargers work well for me, so I'll try and track down a few more of them. Otherwise, nothing is consistent. The desktop I've used has a plenty big enough power supply, and it charges my Epic with no problem. My personal laptop and work laptop both charged the Epic, but not the Photon Q. I guess I'll just have to carry around a charger instead of a MicroUSB cable when I'm on the road with my laptop.
Thanks, all.

All,
For what little it's worth, I just noticed that the words "Not Charging" come up on the lock screen whenever I connect to the USB port of my laptop or desktop. So the PQ knows it's plugged in; it just refuses to accept the charge.
Also, whenever the battery completely dies, the phone will start to charge. It will charge for a few minutes until it has enough battery to turn itself on. As soon as it turns on, it stops charging, and a minute later, shuts down because of the dead battery. Then it starts charging again. This basically gives me an endless loop of the phone charging, starting, discharging, and shutting back off. I can't even get it to stay off long enough to get a useful charge without turning on automatically.
Yeah, the only issue I've had with this phone at all is the extreme 'quirkiness' it has in regards to charging on anything other than the stock usb cord & power adapter it plugs into. Even using the Moto vehicle dock for the Q, its completely hit/miss on charging. It will *often* go into that 'Not Charging' state where its kind of keeping sort of a baseline/'stalemate' of the current charge level for me, not really going down but not charging back up either. Not really sure what's up with that. With my vehicle dock for the longest I kept thinking maybe my cig lighter port on my car is bad, but I don't have issues with my radar detector at all.
Had the same problem with the not charging a few days back. I was leaving the phone in Mass Storage mode because just getting it into Mass Storage was a headache originally.
Hooked it up to it's original cable and woke up with 65% battery. Switched from mass storage to charge only and it started charging.
Not sure if it was caused by being in Mass Storage and wouldn't charge but now I put in Charge Only before bed.
It always works (in my experience) with the original cable that comes with it regardless, its anything else where its quirky.

Isn't there a setting in ##3282# that enables and disables USB charging? Y'all have probably thought of this already. Anyways just thought if throw that out there. This is my first android that was not a low usage device. I know very little about it. I seriously think xda should make tee shirts that say "everything I have learned in life I learned from xda".
My phone was not charging in debugging mode yesterday.

[Q] Infuse 4g wont charge or conect to the computer

Suddenly as it usually happens it stop charging or connecting to the computer. I tried 3 different cables and wall charger. The only thing it does if I turn it off and then plug in the charger or computer cable it will start but it won't charge nor it will not connect to the computer. I think it's the port.

Try uninstalling your drivers for the phone and reinstalling them. That should solve whatever problem you're having with the phone not charging or connecting to the computer because it sounds like all of the drivers needed are not present.
I had this same issue. Mine would charge ONLY if the micro USB was plugged in ever-so-perfectly. The slightest bump would knock it loose, and it would not charge. I ended up buying spare batteries on eBay that came with a battery charger for around $12. Not the ideal solution, but I always keep a battery charged just in case it decides to die. I can get an upgrade in January, so I'm waiting this out.
Also, if you need to connect to computer, I just unplug my micro SD card, and plug that into an adapter and transfer any data that way. I know there is a website that will fix / install a new micro USB port on the Infuse. Sorry I don't know the link off hand, but I have read a few others that have had similar problems.
Best of luck!
