How to charge phone powered off?

I can't seem to find a way to charge the phone while off. If I turn it off then plug the power cord in, the phone turns on. If I plug the phone in then power off the phone turns back on.
Any ideas?
There's nothing to be done about it.
I contacted HTC about this in the past and their take on it is that its the nature of the beast. If the charger is plugged in, then the phone will stay on.
Sorry
Is there a reason you would want the phone to be off while it's charging?
Can't see why you'd want the phone switched off at all.... I'm fairly certain the phone needs to be switched on so it can manage the charging process, monitor when the battery is fully charged and therefore prevent overcharging which would wreck the battery.
But the concept of switching off the phone at all is.....weird. It's an "always on" device!

[Q] p7300 not charging anymore after flashing rom

So I was able flash this Rom http://forum.xda-developers.com/showthread.php?t=2398003 with out any hitches. As soon as the power level goes down to 15% I plugged in the charger while Tab is turned on. It does not indicate that it is charging. So, I turned it off while plugged in. the battery logo comes up and says that it's at 100%.
I turned it back on, now it says it's at 12%, I turned it off and left the charger plugged in for about 5hrs. When I checked the screen the battery logo says it's at 100%. when I turned it on it was at 100% but was depleting the battery fast. I turned it back off, now the battery logo says it's charging. I left it for 30mins. and turned it back on. it's at 8% and cycles from "connect charger" to "charging". Now the tab is dead, it wont turn on. It doesn't even have enough juice for me to restore my back up.
Please, can anyone tell me how I can fix this. I would really appreciate it.

I was using this ROM for a long time and I flashed it over and over without facing any battery problems
so I would say that flashing that ROM caused a battery calibration problem, but sense you can't even charge when your tab is turned off
so I don't think this is the problem
the only thing I can think off is that you should try another charger [I read: cycles from "connect charger" to "charging"]
and yes this might happened, and if you don't have another charger, connect it to your computer for around 5 hours, that would do it
I am currently connecting my tab to the wall, waiting for it to get to 4hrs. I saw this http://forum.xda-developers.com/showthread.php?t=1861229 and am following it right now I hope this works. If it still does not work, I have another charger for the exact same model I could use.

[Q] phone won't turn on

Hi, I need urgent help.
After running my battery down to less than 5% at a friend's house, I turned my phone off, took out the dried battery and plugged a full charged one in. However I cannot get it to turn on again.
If I plug it in (with the fully charged battery), it might either flash a battery icon on the screen then turns off. Or it could start normally (shows the battery is fully charged, but doesn't recognize it is plugged in). But as soon as I unplug the cable, the phone dies.
did anyone experience this problem before? Is this a hardware problem?
thanks

[Q] Battery 100%, after unplugging phone can't start

Hi, first of all sorry for my bad english.
I just bought Motorola Moto G 2 and i tried to start it - white LED lights and the device isn't starting, i thought that its normal that the battery isnt charged because its new phone. I plugged charger and it showed me that battery is about 50% charged, and when the charger is plugged phone starts and works normally, when i unplug the charger phone still works (havent checked for longer time but didnt immediatly turn off, just worked), but when i turn phone off and try to turn it on again LED lights like its discharged.
I tried charging to 100% and unplugging, doing reset but still the same. Only works when starting with charger plugged. What should I do? Is there any solution?

If the led is lighting up for just a moment, you didn't hold the power button long enough. If device is not starting up even after pressing power 5-10 sec.... customer service

Charging Settings

I have a T-Mobile Galaxy Note 5. When I plug in the phone for charging at night, the screen continuously comes on with a vibration, and I get a message momentarily that says my battery is low (I already know my battery is low, that is why I plugged it in). Having the screen continuously come on, really drains the phone more.
Are there any settings that can disable the charging ping that turns on my screen every few seconds?
