[Q] Charging while powered off - HD7 General

Has anyone managed to charge their HD7 while it's powered off?
As soon as I plug in power mine boots up and if I try to shut it down while charging it boots up again.

Same issue here

Well all my HTC devices did it. HD2, TD2, Orbit, Orbit 2 and so on so on.
It is not an issue, software is controlling charge.

the tp didn't do it .

My Touch HD didn't do it.

My HD2 did NOT do this how ever my HD7 does this lol

I just pluged in my HD2 and it boots up ASAP. If I switch it off it stops charging until I boot it up.

I'm finding this issue really anoying, i like to charge during the night whilst my phone is switched off just like i did with my HD2 every night! Really needs sorting.

Just turn on airplane mode and put it on silent.

I discovered last night that the HD7 won't take charge via USB from a powered-down PC. I know the ports are still powered while the PC is off, as my Touch Pro used to take charge overnight.
Wondering if this is a hardware or software issue -- or some weird anomaly of Micro USB vs Mini USB.

my hd and orbit didnt do it but HD7 does as you saing

This probably has to do with the fact that windows phone 7 will perform a wireless sync with the zune software 10 minutes after being plugged into the charger, so the device needs to be on.

Please Help!! Xperia X1 Will Not Turn On Anymore

My battery died last night and i charged the phone up and now the phone will not turn on anymore. Anyone have any ideas cause i'm completely out of them???
have you tried takin git out an putting in the phone again?
Yup. I dunno what is going on. I was using sony's cable to charge the thing and the power button was lit up red and now i switched to a different cable and the power button doesn't turn red anymore but the indicator lights are flashing like it doesn't have enough power to start. It may just be dead and sony's cable just stopped working and never charged the thing
Nope that isn't it... it just won't power on for some reason. i hope someone has an idea as to what is going on because i don't
I had a similar problem and had to leave it plugged in for at least 10 mins before the LEDs indicated it was charging.
THANK THE LORD THANK THE LORD. I was right. The crap cable sony uses just didn't charge the phone at all. Now that i switched i was able to turn the phone on again.
Try hard reseting the device while it is powered, might do something if its a software issue.
battery stone dead~won't recharge
I have the same problem. I don't believe ti has anything to do with the cable. The first time it suddenly came to life after a day or two fo being dead, but this time so far it is still in a coma. It did briefly awaken when connected to the pc, but it kept blacking out, and now it's completely gone again.
Could it be that it is not set to power off until the battery is completely stone dead, and therefore it won't recharge?
I think you are absolutely right. I don't believe it allows you to charge it until it is turned on. So try and plug it for like 15mins and try and power it on. Let us know if it works
This sounds like what I have seen on more than one device. If you let the battery go completely dead it will not take a charge from a USB cable to a PC or hub, even if it was a powered hub. We had some old HTCs that would only take a charge from a transformer when the battery had been fully depleted. It was like the USB to PC or hub did not give it enough amps or watts to turn it on and start charging.

Came accross this also in the Kaiser forums - think it has something to do with the battery being absolutely drained, so much that there isn't enough power to switch the current to the battery again.
Never happened to me, so never quite figured it out. But the Kaiser forum had a lot of discussion (and solutions I think) on this. (Xperia has HTC involvement..or so it's rumoured).

yep... I have had that happened to my blackjack 2 a couple times too. everytime I had to connect it to the charger for like 10 15mins before it can turn on again... plugging it to the pc/hub never work.... also happened once to my iphone as well
Hey I just ran into this problem today.
Turns out it was activesync messing with the phone
Ended the mobile device center process in task manager and phone went back to normal.
EDIT: Ok maybe its not back to normal. But it was definitely caused by activesync...
EDIT2: Back to normal now... Had to plug in the wall charger. After a minute the charging lights flashed and i was able to turn it on.
Checking battery status, and its in the red.. I guess the activesync was just a coincidence.
But wow, I left the thing plugged into my computer overnight to charge, and apparently it drained more than it charged?
There is defiantly something extra going on with the Xperia. While other devices I’ve seen fully drained refuse to start charging again from a USB to PC cable and even some power outlet charges. My Xperia is also doing as Nipperos. With an almost full charge I plugged it into the USB to PC cable and the icon went to the little plug and when I clicked on it the status said that it is was charging but when I got ready to leave for the day it had drained down one red bar. It was also very warm. With this, the $800 price tag and the random crashing made worse by the incredibly poor location of the reset button and made even worse by the incredibly poor design of the battery cover. Really, what is the proper way to get the thing off without breaking it? I’m fighting the urge to return it.
Any word on a new firmware?

I've noticed this too... My phone will be on full charge, i connect it to my PC to install a software, then i check one bar's gone... it drains more than it charges...
my x1 did this today. my buddy has a verizon htc phone and let me use hus htc wall charger and it did the trick...
my x1 is a x1i so i dont know if the US. plugs or what dont agree with the phone. but out of 6 cables and chargers only 2 will charge the phone from a dead battery the other 4 would only charge after it was on.
so my best solution for you all is to find yourself a htc wall charger and let it charger for 20 mins before trying to turn it on.
and of course theres htc involvment on the x1. look in the windows folder. all drivers are HTCxxx.dll the comm manager is htc. theres a forum here the htc developers site. this isnt a site for samsungs and other makers. this is a site for htc devices. if it wasnt a htc device it wouldnt be here.
My experience
I had a similar experience while on a trip to Korea. I didn't foresee that a 200mA difference in the current output of a wall socket charger will cause me so much pain.
I had always been able to charge the X1 with my Jabra headset's wall socket charger, hence I brought it on my trip. Not being mindful of the ratings, it can only supply 500mA, which is different from the X1's charger, 700mA. I was using it happily on a bus, happily keeping it alive with a solar USB charger (till it ran out of juice too). A while later, playing with the GPS I noticed my battery power dropped to 20% (2 bar) so I pressed the power button to conserve energy.
Unknowingly, the battery kept draining and the next time I wanted to turn it on I couldn't. The top 2 LEDs gave me 3 red blinks. I thought, "ok, so I just go back to the hotel to charge it with my Jabra charger."
When I tried that, I noticed that the power button gave a constant red LED and the battery did not charge. Taking out the battery and putting it back, I noticed the power LED went off (which indicates it was going to charge) but came back out again. It never charged.
Back home, after using the supplied SE charger, the power LED went off and never came back. I tried to turn on the X1 after 15mins and it powered up, showing the usual charging LED cycles.
Lesson Learnt. Always use original accessories.
Same problem here....
I knew about problem charging totally dead battery with wall plug-in (from previous HTC). Totally dead battery was not possible to charge via USB (from PC). But I have bought xperia via ebay and didn't know the wall charger is not original SE charger... Hope to work with previous HTC charger
Tx for coming to the idea
Just happened to me :S
I had used it all day and Wifi was turned on so obviously battery was almost dead. To save battery I turned off the Xperia.
When I tried to turn it on again it wouldnt and so I connected it to the pc.
That didnt work out so I connected it to the standard charger but that also didnt work. Right now my Xperia X1 is lying unplugged on the table because someone said you should leave it unplugged for a couple of minutes.
Hopefully it will work, I only have had it for 3 days :´(
Also hope this doesnt happen everytime your battery is drained because that would be annoying as hell.
--Edit--
Ok so what I did was I removed the battery and plugged it back in. This worked and I managed to turn it on and right now its charging.
Though when I try to go to sleep mode it turns the display on again after about 3 seconds and does what I am guessing is a low battery beep (Sorry windowsmobile noob here) but then stops instantly, which is pretty stange.
ok anyone know a way to increase the power wattage from your pc to the usb device? (sounds dangerous i know), but there must be someone who has had a similar prob and was able to fix with a bit of tweaking....ill google and come back with any results
okay...i had similar problem today morning..it wudnt start.
so i left it charging for ten minutes...and now it has turned on finally.
i think the battery goes completely dead.

[Q] Battery discharging when on powered USB

Here's an interesting discovery - would be interested to know if anyone else has the same issue.
Basically, my old WM6.5 phone (Touch Pro) used to take charge from a powered USB socket, even when the computer was turned off.
Plugging the HD7 into the same USB socket, and the phone won't charge. That's fine, I can understand there may be valid reasons for it.
What's *really* interesting is that if I leave the phone plugged into this powered down PC overnight, the battery is pretty much dead in the morning. Compare this to leaving the phone unplugged completely, and I'd generally see 15% battery usage overnight.
The solution is pretty simple - don't leave the phone plugged into this USB socket, but it seems odd.
Any chance someone else can try this?
Is the Zune client on your pc open because my phone will not charge with zune open
but once i exit out of zune on the pc it charges fine...
ive lost my charger and too lazy and cheap to buy a new one so im just using the pc to do it....
no - the PC is actually powered down. However, with soft power switches, the USB port stilll can get power, as proven by my ability to charge my Touch Pro from USB when the PC's off.
I'm not sure what could be causing this, but i will try to see if mine is the same too, then i will post feedback
I've charged mine on a USB port at work, but there isn't any Zune software in the way there... Honestly, I don't sync through USB, so I never noticed this, but at work I have used the USB port on our camera system to charge my phone...
most likely cause is the fact that the computer reduces the amount of current send to the usb port when powered down.
normaly all that is needed is a move of the mouse or a key press to power the computer back on.
now both the keyboard and mouse are low power devices.
now my guess is that the touch pro needs less power in standby then the hd7, and therefore the first will charge and the second will drain.
so to solve this question you need to measure the power comming from the computer in standby (powered on it's 500mA), and both the phones in standby mode.

Here's what I find odd:
The phone will not charge unless powered on. For example, if I have the phone turned off, and plug it into the wall charger it came with, the phone boots up. It will NOT charge while turned off.
Anyone else notice this?

i saw someone mention that the led won't turn on during charging while the phone is turned off.
sadly he didn't wait long enough to see if the led turns on when the battery is fully charged.
also i have no idea which model he was using.

I posted earlier about charging issues on the HD7: http://forum.xda-developers.com/showthread.php?t=849548
What I found was that if you have the HD7 plugged into the USB port and then you suspend/shut down the PC, it'll stop charging (while all other phones I've used - iPhones, HD2, etc. - will keep charging).
Once you suspend/shut down, you need to then unplug and replug the HD7, and it should start charging again. Not sure why this happens, but I need to do it every night, otherwise I have a dead phone in the morning.

That is apparently a "feature" of WP7-- the phone will automatically turn on when plugged in.

[Q] Phone DEAD! Just vibrates when plugged in and flashes HTC screen

I have a 100% stock HD7 from Tmobile Im not sure how, but it just stopped booting. On battery it will not turn on at all, but if I plug it in with the volume down I was able to get into the tri color screen and so I was going to flash a stock firmware, but before I could it powered off and just started flickering the htc logo and then vibrating then shutting down then doing this in a loop.... Any ideas could it be that the battery is just dead, but if so why wont it just run while plugged in? Also while plugged it is says it is a pd29110 as well as a touch s1.
Thanks!
If from what you have said I would try another battery and see what happens from that point then on.

I read somewhere to pull the sd card so I did that and it didnt work so I put it on a cheapo wall charger and it didnt light up but I left it and now it has charged and turns on! But now my sd cards says its only 12 mb... Anyone else ever had this problem?
This is typical (imo). This happened when i first plugged the phone in from the shop. Happened again with a completely drained battery. Just plug it in and it cycles... So i pull the plug and plug it back in and it usually catches itself.

[BUG] Possible charging bug from computer USB port

Hi
I'm not sure if this is related to just my particular computer or a general charging bug. Several times I've plugged the Nexus 4 into my computer USB port to charge overnight (okay it's slower by USB but overnight it doesn't matter and convenient to use the computer USB port) only to find it hasn't charge but continued to discharged.
My computer USB ports are powered while the computer is in Sleep mode (suspend to RAM) and I've charged many gadgets over night with no problem, including the Nexus 7.
To replicate the bug:
1) Computer is on, plug the Nexus 4 in to charge, Nexus confirms it is charging by icon in notification tray and it will start to charge
2) Computer goes to sleep, Nexus 4 still shows it is charging, however at this point it is no longer charging, and actually starts to discharge quicker than normal.
3) While computer is still in sleep mode, unplug the USB cable from the Nexus, plug it back in, phone now starts to charge normally.
There seems to be a bug when the computer sleeps and disconnects the USB data part of the connection, the Nexus gets a bit confused and stops charging even though it still indicates it is charging. I suspect the faster discharge I've seen is because the Nexus 4 thinks it is powered and doesn't deep sleep as it would on only battery power.
An HTC One X, a Nexus 7, an MP3 player and numerous other gadgets have all continued to charge normally after point 2.
Thought it worth pointing out in case others have similar issues and wonder why the phone isn't charging.
Regards
Phil
Noticed the same just a day ago, went to take my phone off charging from my laptop and was very surprise/d/ that i had lost 2-3%

Same here with Mac. Once goes to sleep it drains phone even though icon shows its charging.
I've noticed this too. The Nexus 4 is my only device that won't charge from my PC while it's sleeping.
Edit: Actually I need to use the PC, so this isn't going to work
Had this happen too. Is there a fix? or is it just like that
Thanks for this. I wandered why my phone was 0% one night I had it on the charger all night.
Mine shows the charging symbol on the statusbar, but at the battery screen in settings it shows it isn't charging,
Screenshot included.
Screenshot was taken when my laptop was in sleep mode with my nexus 4 connected over usb.
Had the same thing happen to me.
Well, after JB update 4.1.2, the same happens with my GNex. So it must be OS related.

This is super annoying as that's how I've charged my phones for years. Now I have to put the stock wall wart somewhere and have an extra long USB cable to reach my desk. Sometimes I forget about this bug when developing stuff and it says "charging" so I wake up with a dead phone
I'd noticed this issue when charging with a battery pack, though I haven't tried it from my computer USB port yet. One thing - if the phone charge is above 50% it seems to be fine, it's only when it's below 50% that it doesn't recharge from the battery pack. Has anyone noticed something similar when charging from a computer USB - does it work if the phone battery is over 50%?
Same here--my Nexus 4 doesn't charge by a sleeping computer. Every other phone worked fine (though I had to connect my iPhones before the computer was asleep for them to continue charging after it was put to sleep). I've tried this when my Nexus was over 50% and with two different cables. It also worked with my Galaxy Nexus from OS 4.1 to 4.2.
I have the same thing when I try to charge it over a powered USB hub (you definitly get 5V from it) while the PC is turned off... It shows that it is charging but it is not.. really annyoing especially when you use it as your alarm in the morning (don't ask, that is how I noticed it the first time ). Never had a problem when the PC is turned on though...
something like this happens to me but charging with AC adapter...it would say connected to AC then after awhile when i wake the phone up, it would say charging with USB but it is connected to AC adapter...to get back to charging as connected to AC, i would have to unplug and replug...weird
Try different USB Ports and other USB cable.
I have a notebook which has on the left side 2 USB ports and on the right side 1 USB port.
The mobile doesn't charge with original USB cable on any of these USB ports.
But if I use a standard USB Cable and plug it into the USB port on the right side, mobile gets charged over night.
However, when plugging in any of the USB ports on the left side, it won't get charged.
(Left side is sharing the 500mA, right side won't)
And yes, my computer is put to sleep, just keep the USB ports alive
Yup is also happens to me. I think it is a bug, might as well use the mains as it works better and it charges very quickly.
4.2.1 has a lot of bugs that needs to be sorted out in my opinion, and this is one of them.

It's a bug with the Nexus 4. I have tried the same USB port with a:
1. Nexus 7
2. Galaxy Nexus
3. Galaxy Note
4. Motorola Charm
All except the Nexus 4 work fine charging when computer is in sleep.
Hi
Fingers crossed this is fixed in the next OTA happening shortly. In the change log we have this:
5194a3d power: charger: need sometime to handle the usb disconnecting events
Fixes listed here
A computer going to sleep would cause the data part of the USB connection to disconnect, if this event is now handled correctly by the charging system perhaps it will continue to charge normally after the computer has slept. Like I say, fingers crossed but looks hopeful.
Regards
Phil
A work around that most of you probably know is that as soon as your computer has been put to sleep, unplug the cable and replug it again. The phone will start charging again.

Droid 4 close to brick...

Hi everybody...
I have an issue for you...
Yesterday I was using my phone and battery was aboout 40%.
I then took out it from my pocket to switch on the screed and it didn't switch on...it seems the screen was on but black...
- I tried to press the switch button, but nothing...I connected it to my portable battery and nothing too...
- I tried to switch on by press all three phisical buttons and I had a short vibration and nothing else, just another vibration after about 20sec...
That makes me feel that situation was possible to fix...
Of course the battery couldn't be removed and put on again...
Finally I arrived home and I connect to electricity and nothing, I connected to my PC and I reboot the phone by the utility: it works!!
I was worried and I would like to know what happened and if that's possible to repeat again...
Thanks!

This phone doesn't play nice with a lot of portable battery chargers. Try it with the charger that came with it?
A short while after you plug the charger in, it should appear to boot and display only a charging screen. Once it gets to 10% or 15% you can pull the charge cable out, power it on normally and then plug the charge cable back in.
Oddly, Nokia micro USB chargers seem to work well with this phone, if you have one of those spare.
Hi!
thanks for the answer, but you maybe misunderstood, I know about difference between charging from portable charger and normal...it happened with my backflip when it was completely empty...
Maybe I didn't explain well...the phone went "off" alone, but I was sure battery was about 30%...and it didn't work, just the screen on and black...
In my case even normal charger didn't work to reboot phone...
My solution was just to connect to computer and reboot with the tool...
but I don't know what happened, till now it didn't happen again...
p.s. I have a portable charger bought on groupon, that it works, but it's extremely slow...
bye!!
