Trying to charge phone while it's off automatically turns it on - Windows Phone 7 Q&A, Help & Troubleshooting

I noticed today while I was trying to get maximum charge in minimum time that after I turned my phone off and charged it, it automatically turned on. After I noticed this while it was still plugged in I shut it off again and much to my dismay it turned on again!
I'm on the HTC 7 pro, anyone else confirm this issue?

Phone will not turn off if USB charging/syncing; must use AC charger. Another alternative is to buy a second battery & wall charger specific to that battery; I have this setup for my Samsung Focus, but use it infrequently.

Would you mind testing something?
Turn off your phone, plug in the AC charger and see if the phone automatically turns on automatically?
Then if it does turn on again shut it down again while it's still plugged in to see if it turns on automatically again.
Thanks, I'm trying to see if this issue is unique to my device so I can report it as a bug.

Windows Phone 7 works this way. I was a bit surprised too, but the explanation from MS was that the charging circuit in the phone is software-controlled, and in order for that software to run, the phone must be on.
Yes, I know anybody with a modicum of software design experience knows how lame that sounds, but that's the "official" explanation. You *cannot* turn off the phone while it's connected to external power.
The good news is that while charging, the WiFi is left turned on, so if you have a WiFi connection, you're not using 3G data in this scenario. That was my primary initial concern (but not the only one).
Brad.

So since it's software controlled it must be possible to disable it through some option.

if you disable it, you will lose an option to charge the battery...simple as that

I guess this is yet another feature I enjoyed with WM that I can't (hopefully yet) enjoy on WP7.
I don't understand why you would make a purely hardware thing like charging into software...

Well, I don´t really undestand why is it such a problem, you can still turn the airplane mode on, this way there will by no cellular transfer, and put phone into sleepmode, if you do this, what do you think, by how much slower you would have your phone charged compared to turning it off? 5 minutes? Well that´s an achievement...

I wish I had two identical devices and I could run an actual test on this but I can only use my old TP2. I've always been under the impression that if your device is charging while it's off that it charges much faster than if it is on (consuming power) and trying to charge at the same time. It's always made intuitive sense to me that that's the case.

unless there is some sort of software based charging optimization involved.

New Fuze new problems

So i got my new fuze and now there is another problem... This is a small problem, when my fuze is connected to pc through USB, it doesnt seem to get charged and the battery goes down pretty fast. I have already unchecked the battery option and changed the phone to turn off in 1 min. The backlight turns off after 30 seconds but screen is still on and so is the phone. I use Energy warhawk8/11 and radio 1.14.25.35, could this be the radio or rom? i have also tried to restart phone and pc and also tweaked the battery options with registry. any help please
check the temperature of the phone. if it's extremely hot then that's why..
By the "battery option," are you referring to start>settings>system>power settings?
Not the option
Yea i meant the setting battery options, its unchecked and i have the timer to shut off after 1 min... the phone syncs fine with comp but doesnt charge and screen doesnt turn off... also the temperature is fine
i probably assumed that you resetted the phone already... If that is still not working, try a new usb cable. you should have plenty lying around (if you have an external hdd you should have a usb - miniusb cable)
When you connect via USB does the phone ask if you want Activesync, file transfer or modem mode?
Active sync
Yes the phone syncs with pc and it says the phone is charging but the battery is draining... It doesnt seem to shut off after 1 min and if i shut it off manually it charges slowly, i also tried diff computer and wire... could it be the rom?

So, now we're getting the information you should have originally posted "it says the phone is charging but the battery is draining". You originally stated that the phone was NOT charging, when in fact it is but draining faster than its charging, right?
When asking for help, it is best to give the best information up front, be thorough in your description, tell us what ROM\Radio you're on, what symptoms you're experiencing, have you tried to fix it, if so -how? etc., etc., etc.... And you had better have searched for a fix first!
You had to have 8 posts to your question because you asked it incorrectly.
Don't look to be spoon fed and don't waste the time of people who are trying to help you.
Now on to your issue,
If you are running WiFi or GPS while sync'd, your battery usage will be greater than the rate of charge. Other things like streaming musiic can do this too.
Also as Thresher stated below and I forgot, your Radio can also cause this which is why you were asked if the phone was gettting hot. Typically the battery gets hot and then stops charging. I flashed back to 1.13 Radio from a 1.14 radio for this reason.
If your battery is just not taking a charge, then its a hardware failure.
Flash a stock rom and radio combo to it. I would use the latest from htc for att. sounds like hardware issues though. Inman is correct.
Hmm
Sry about that inman
Hmm
Sry about that inman
Now for the problem, it charges fine on AC but when connected to pc, the phone doesnt turn off and drains battery even thought its stating charging... I had 1.14.25.35 before and tried stock radio but didnt help. I dont have anything runnung on the phone... One more thing it seems to charge when i manually turn it off from the shut off button, i dont know if i should exchange the phone again for this minor issue
I don't mean to flame you, its just one of the biggest problems with this forum.
It all comes down to read, search, then ask, and offer anything you can.
Its outlined very clearly here.
What you describe doesn't make sense. It should not use more than the charge it receives if nothing else is running.
I do not know of a fix, nor can I replicate this issue.
You could try a battery monitoring program that will show you where you're losing your charge.
I would say, if you can, return it for an exchange.
Dark - you may have a minor issue (depending on what your phone is trying to do) or a major one (if it isnt supposed to be doing it!).
* Whilst on USB your phone can only charge at USB current (i believe 500mA [per passive port], 5v), if your phone is drawing more than 500mA [or others on the same port are], it will (overall) discharge.
* Assuming it IS CHARGING from the USB (and this is kinda significant) then your problem (if it exists) is an excessive discharge.
Basically Bruce is right - if you have your phone drawing a huge current (its working is [email protected]@cks off - and you know this) then this isnt a fault - simpy, a limitation of USB!
* If you don't expect your phone to be drawing a huge current then you need to look into this (charge to 100%, do a soft reset, plug into usb - observe to confirm) flash a new radio, a new rom, stop or uninstall apps - basically see wtf is taking all the juice.
* If the phone isn't charging then this is a different problem again! Check your pc, lead, settings & finally wonder about the phone (or pc) hardware.
If you need help - do everything you can do (or are happy doing), then tell us everything you did - and why - and what you found. Then others can help.
Please don't ever assume something you dont know about is not important - it might be! Someone else might use that info to fault find your problem.
Edit:
Regarding Bruce's comments about not seeing or being able to reproduce this error - i have, in the past, suffered for both "excessive" and "omfg f'ing crazy" battery drain. The latter i solved with a couple of soft reboots - although i had the problem several times, the answer was always a couple of back-to-back soft resets [in these cases, the phone was on the mains charger, and "charging", yet still was drawing too much current & the battery was overall discharging.
In the "excessive" version, i believe (my phone has been repaired & had hw replaced) the problem was the radio - or possibly the radio vs rilphone.dll file. Since these episodes i have a new main board, new rom & new radio so it is impossible for me to say 100% what the cause of my "issues" was, but i'm 95% sure it was radio/rilphone related.

Windows Phone Touch Screen Multi-Error

Hi guys, i am having the HTC HD7 with Nodo 7392.
This is the video about the problem i am having
Link (if you cannot see the video) : http://www.youtube.com/watch?v=ZUcEyB_jxAc
Let me describe the problem:
I plugged the phone charger in for my HD7 to recharge the battery the whole night. On The Morning, i woke up and tried to get on the internet for a while. Now i found it extremely hard to control the phone in the way i want. When i tried pinch to zoom, it isn't smooth at all, very junky. And if i hold my 2 fingers, my phone will be crazy, it open many things... random apps....random lines....
The temperature of the phone was normal, i didn't feel any heat from the back.
This thing can be done only with the charger on. If i remove the cable, everything go back to normal.
Does it happen with you guys phone?
I have the same problem with my Omnia 7 (but not with USB cable) :s
I haven't got any solutions
Mhh I think flash the phone new.
My Omnia 7 hasn't this problem.

This is a fairly common occurence. There is nothing wrong with your phone. It seems like the current of the charging interferes with the capacitive screen's ability to precisely recognize touches, but it does not always happen.
The also happens with my Zune HD when it is plugged in.
You guys can see, when i removed the cable, the problem dissapeared right away, and went back again when i plugged the cable back.
Find it so hard to type, the phone went to all kind of program that i didn't allow or command the phone to do it...

Yeah. I have only ever had this issue when it is plugged in, never otherwise. It would be nice if they were to figure out how to fix it as it is useful to have it plugged in while using it.
This thing is still exits on Mango Beta 2. i am starting to think the BIOS of the Phone cause the error.

Screen doesn't respond when plugged in wall charger.

Yesterday I missed a call because screen didn't respond on touch, I was blaming on tithering (which by the way had rebooted phone twice today), but today I've noticed when this happens and I unplug the phone, it instantaniosly fixes the screen (and buttons as well), plugging it back in, freezes it. Was playing with it for a minute just to make sure..
Anyone experiencing anything like this?
P.S.
Installed "CPU Guage" which shows cpu load in real time in tasks bar, I can see the numbers changes but nothing above 30%, so it wasn't CPU overload
i haven't had that, until about 2 minutes ago. funny this was posted just now, i just logged in to post about it, lol. but my phone has been fine, until just now. i plugged it in and when to change it to mass storage mode and it wouldn't respond. then it was kind of weird when it started responding. it eventually worked, but took a couple of swipes.
---------- Post added at 06:39 PM ---------- Previous post was at 06:37 PM ----------
i also notice that when unplugged, i get around 44-45 linpack, plugged in, around 35
Nope, just tested it, plugged to the wall I could answer a call normally.
it might be because of short circuit, check ur charger or charge with another charger or cable see if it happen again.
I have it too. Anytime its plugged in it will be super laggy and/or freeze.

I haven't seen this issue on the Atrix 2 yet, but both my Samsung Moment and Samsung Epic would have screen responsiveness issues while plugged in, so it is behavior I have seen in other Android devices.
I havent had this problem. When I go to bed I put my phone on the charger, wall type, and will usually mess around on the phone for a little while before setting it down for the night. Not once has it given me this problem.

I don't have this problem all the time either, it happened only twice in two days. Just now checked it again - no problem whatsoever...
Perhaps if we trace what is running and/or what was running before this happens, we could figure something out.
Today I was using pandora, sportypal (which by the way consumes 40% cpu at times, on Atrix 4G never had this problem) and then after these two apps where closed I used mobile hotspot.
On background two apps are always running: battery cyrlce and nettraffic (there are many more apps started but they seems to be inactive, like skype which doesn't log me in automatically)
Oh and it could make difference, I use ADWLauncher EX
I don't have any of these problems. Get up every morning and check missed calls, emails, texts and FB notifications all while being plugged into the charger. Had someone call me and I answered it on speaker phone to make sure I didn't have any problems receiving a call while plugged in either
No problems so far, but I am completely stock. Phone was purchased on the Nov. 11th
wow, just had it happen.
Don't have this problem either but I am completely stock also.

I don't seem to have this problem in the morning either, I notice it at about 11am - 1pm
Today I've killed every apps that was running (excluded services), but it didn't help at all. I still suspect mobile hotspot though, it doesn't work properly...client's get disconnected, then would not able obtain IP.
OEM charger and cable only
Make sure you are using ONLY the OEM charger and OEM cable to charge your phone. They provide an extra ground path not normally supplied which is needed by your capacitive touchscreen to function normally. A "normal" micro USB cable or USb charger does not provide this.

I have a charger by my bed, a charger in my work van, a charger at my desk at work and a charger on my pc....of all those, only the one by my bed is the oem charger and the oem cord, my phone works perfectly on all of them.
Ok, it has nothing to do with the type of charger, it even happens when connected to PC as storage or charge only. Changing cables also have no affect.
Me too

I had this happen A LOT! Happened almost always with one particular charger, rarely happened when hooked up to computer USB port. Never happened in car using Griffin iPad car charger.
This was one of the frustrating things about the phone for me. Just sold, and have Galaxy Note on the way.
Hey people I have this similar issue... was searching xda for anything like this but seems this is the only place there is some issue like this happening...
I have a Galaxy S2 Running Cyanogen7 ...
Now here's what IV noticed... on stock charger I have no issues at all... nor when plugged into the PC... just today it happened and I was using a iPhone charger with a OEM Samsung USB cable... it was charging fine but the screen just wouldn't respond... as soon as unplugged would be fine... so... I'm thinking it's this charger maybe giving too much power to the phone... as my stock charger is 750ma while the iPhone one is 1A... that's the farthest IV been able to think... :s

motorola contacted me to send them my phone and car dock, and they would swap them with new units so they can use mine with testing. you should go to the motorola atrix 2 owners forums and talk to mark
I've owned this phone for roughly 36 hours. I noticed last night (which is the first night owning the phone) that when the phone is charging, it doesn't seem to acknowledge my finger touching the screen. Since the phone was new, the only apps downloaded at the time were:
Lets Golf 2
Angry Birds
Tiny Bee Demo and,
AVG Anti-Virus
Things to note:
I did download the 3 games before the anti-virus program, so the possibility of a virus is there, but not likely.
I also didn't delete any apps or change any major settings that might cause the problem.
One other odd thing I noticed, I was in the middle of a text when I plugged in the charger, and that somehow made it insert a letter. I thought it was odd so I made sure it wasn't me touching the screen and tried it again, and it typed two other random numbers.
I hope this helps somebody somewhere find the fix to this problem... :cool
Edit: I have an Atrix 2

#1 if you are downloading trusted apps, you don't need an anti-virus

Turn on phone without battery

Hi folks!
I brought a HTC Sensation on eBay, but until now, only the phone and USB cable arrives.
So i need to know if is possible turn on the phone only with USB cable and (wall) charger, without the battery.
Is it possible?
Does damage the device?
No it's not possible. You need battery

you pay with what? if you use paypal definitely you'll get you money back.
I wish modern phones were able to turn on without the battery, while plugged in, like the old phones used to. Dunno why they stopped, but it came in handy when your battery was bunk and you had to use the phone, even as a corded handset, for a while

Probably because it's possible to use more power than what is coming in, so they removed the "feature" for stability reasons. Using Google Maps for navigation with GPS on and the screen brightness all the way up can do this, and some people will even have bluetooth enabled to tether to their car stereo, draining the battery WAY faster than what a charger can push in.

Your right. There's also a chance of eMMC damage or data corruption/loss by loss of power. In the end, letting you connect a flash memory phone to a computer and switch it on without a battery will only hurt the device.
Btteries must have at least a 1-2% charge before the device can be powered on. Your sensation will flash it's amber LED to warn you if the battery doesn't have enough charge to turn on while the phone is connected to a charger.
Thank you so much guys!
I'll open a case on eBay and buy other battery.

[Q] inconsistent battery charging - any help?

Hi guys,
Been having issues with charging for the past couple of days. When I plug my phone into the charger it states that it's charging, but nothing really happens. The troubleshooting so far:
Have tested it on multiple different chargers, all having same problem. However, my Nexus7 tablet will charge normally on these chargers, so we can rule out it's charger related.
Tested for differences with the phone switched on or off. When phone is switched off it will charge, but not with the speed it normally does.
Running CM11 Snapshot M9. Did a clean install. Battery does not charge normally (read 1% gain per 20 min) on most stripped down version (without gapps + personal apps)
Looks like it's battery related. But I find it difficult to rule out what's causing my phone to act funny. The weird thing is that sometimes my phone will go for a decent charge, but this happens so randomly that it's hard to find any form of sense in this process. Also, when the phone is on and charging, the battery light will sometimes turn off. But when I activate my phone again, the battery light will bleep on as if nothing happened and everything is functioning normally (which is clearly doesn't).
Does anybody have an idea how I can fix this? Any helpful tips that can point me into the right direction to figure out what's causing this? Many thanks in advance!
did some more testing - can anyone help me out?
After some additional testing I'm fairly sure that it's either battery or chip related:
USB debugging does not work at all (storage is set to MTP). When I open Android File Transfer my Mac will recognise the Nexus 7 tablet, but not the Nexus 5. Debugging is switched on in Developer options.
When I try to use adb or fasboot, my device is not listed either, nor are any commands (directed towards phone) executed through bootloader.
In the about Phone section I went to check the Battery info. It will state correctly that the phone is being charged through AC or USB (depending on wether the device is connected to laptop or charger).
Does anyone have an idea how I can figure out if it's chip or battery related? I desperately want to find this out, because I bought my phone in The States and live in Europe... So in the worst case scenario the phone needs to go back to the US due to bureaucratic policies. Already had to go through this horrible proces half a year ago with a bad NAND chip, really want to avoid the hassle and lose my phone for at least a month. So if it's a battery thing I rather order a new one and replace it myself
Really really hope someone can shed light on this issue, running out of luck and options. Please guys, please :angel:
sounds like the usb connection, physical, is going. if it doesnt charge but randomly will, fastboot nor adb see it, i think its an usb connection issue. i had the same with my nexus one a long time ago, if i wiggled the the connection when it was connected, sometimes i could get it to charge some. fortunately, it isnt an expensive repair, and yours should still be under warranty.

Thanks for the reply, really appreciate it How much you reckon it will cost? Also, can I do this at any decent phone recovery shop? As stated previously, really want to avoid sending the phone back to the US. Once again thanks!
