Charging while phone is off?

Hi,
Yesterday I came across strange issue. In WinMo, when the phone was off it was charging normally untill the battery was fully charged...
After Flashing Android to NAND I can not do that. It seems to be charging (orange LED is on) for about 10 sec. and than the Display blinks with white light and the phone dies completely.
The only thing you can do after that is to pull out the battery and put it back. Than you can turn the phone on and charge as usually.
What is that issues origin? Battery driver? Or another thingie in Firmware? It seems to be quite strange, that it lights the display even with the phone being off...

My Kaiser does the exact same thing, and what it is, is for some reason the phone is booting back up. I came across this the other day, and my phone did the exact same thing described, and not sure what I did, but I managed to turn on the screen and Android was booted up to the lock screen.
It's even done it when I plug the phone into A/C power without the battery even connected.

so here is why it happens, basicly what would happen is in WinMo when the phone would turn off and boot into a charge loop and it would charge and shut off when finished our kernel doesnt have this built into it so it just boots like normal when power is applied

yup... happens to all of us, its not a big deal... there are a lot of worse problems devs are trying to solve... maybe whn they reach a point where the kernel is more stable they should pay attention to the details like this (and the camera driver, camcoder... etc)

Well that answers my question... Yah knew it was something inside the kernel, just didn't know if it was a bug, or something that wasn't implemented yet.

Of course this is low priority task but I just wanted to have that confirmed to know, that my oldie holdie is not broken or what

Quick question:
How old is your kaiser and/or battery ?

About 5 years with original battery

It used to be that if Linux NBH was flashed, the phone wouldn't charge at all when off. Then somebody (dzo I believe) added code to the kernel so that the phone turns on when it is plugged in, so that it will charge. That used to work, with a full complete boot. Now, as you say, the phone tries to wake up but doesn't really make it. Maybe we should look into that, we should be able to fix that, maybe by looking carefully at the git logs for the past six months or so.
There are bigger problems, like data reliability, but if somebody wants a problem in the kernel that they can study and perhaps fix, this is a good one to start with.

To correctly charge the battery system need to be on so i can do this:
start kernel
in initrd:
if it found the power connected then the phone wait for power button (trying the sleep mode)
else
start the system
i need some testing to do it.
Windows do quite the same thing.

If only the real code was as easy as the pseudocode =)

Couple questions about rom manager

1. When I power my device down and connect the charger ClockWorkMod Recovery pops up, Why is that? Is there a way to turn that feature off so my device is completely turned off while charging???
2. Is it safe to charge in recovery? To leave the fone idle for a number of hours can't be safe especially with the words and icons being displayed don't want those images burned into my screen. . .
3. After powering down at 99% I let my battery charge for a bit and not even a hour later I see the fone rebooted itself and I'm back at my home screen with the battery saying 'charged' is that normal???
Thanks in advance

1. It's a bug. 4EXT Touch Does address this, as well as a plethora of bugs from CWM.
2. Yes - I had also experienced the above bug when I was using CWM. I put my phone to charge, then slept. Next morning, the phone was idling on recovery. But I still strongly suggest you use 4EXT, as it is faster and safer.
3. Never heard of this...Ideally the led will turn green, but the phone won't turn on by itself.

I'm using a new 1520mah battery from the EVO 4G Design maybe that's why the device rebooted? not too long before this I left the phone charging for say 4 to 6 hrs and the led never turned green it stayed at orange.
When I rebooted the battery info said 'charged'

Highly unlikely. My guess is it's another issue with CWM. For all we know it could be a random tap of the power button, after all that's all it takes to power it up.

Charging my DZ almost every night and never had this issue.
You should consider using 4ext instead of CWM.

Older version of cwm had that problem, but was fixed a long time ago

The issues still present, I'm using the latest version of cwm.

For me, i always charge my phone only when it runs out. When i plug my charger in, it boots to recovery, but if i leave it for a while, it just shuts off. It seems that CWM doesn't stay on when my phone is on low battery or something.

Charge when it reaches 10 - 5% then tap the power button as soon as you see the recovery menu pop up, it'll bring up a screensaver that should stop it from shutting off.

Don't know why anyone would day 4EXT is "safer", though I'm happy to be educated.
If you leave it for a minute in that state with CWM started, the screen will turn off again so it's no problem, just a slightly irritating bug.
Sent from my Desire Z running CM7.

Well, from experience with CWM5 I had a lot of issues with backups. Either MD5 checks would fail or booting after restore would have me stuck at the htc screen. So from that aspect of view, 4EXT is somewhat safer. On second thought, reliable would be a more fitting attribute. Just my 2 cents.

It is for motorola, will it gonna work on htc ? Also when I charge my battery for 4 hours or for 48 ( turned off the phone I mean) it still lightning red led not green. Always it charged till 71 %

Worked for me on my WF using CM 7!

Okay I will try this, nut what about app Battery Calibration, does it work ?

Don't use an app because it is software based, but the guide i've posted is hardware based!

Ok thanks for the information !

1. While in Android, charge up to 100% and leave the phone plugged in.
it dosen't charge up to 100% to use this method

In this case 100% are the maximum you can reach. You can check the exact battery status in system settings!

1. Sorry, haven't thought about that. Yes, it has to be rooted.
2. If your phone is rooted you can find it with root explorer.
3. Yes, for rooting your phone needs to be S-OFF
Maybe you can use that one - found it in another topic:
1. Power on your phone then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Needs no root, but I haven't tried that yet. Most of the users said that it worked, but keep in mind that battery calibration can always damage your battery.

My battery never charge up to 100% last time i saw green light from fulfully charged phone was last year. I can charge it for 48 hours turned of it still wont be green

Which status is shown in phone->status->battery status?

Problem with ROM now I can't charge

I installed the ARHD 7.0.0 ROM on Monday everything was working fine, I also installed the SMooth Rosie MOD and still everything was fine. But today, I lost my phone signal and though oh well i'll leave it whilst I go to the gym, I came back and the bttery ws at 23% (Was at 91% when I left it).
I rebooted the phone and it would get to the lock screen (with no ring) then it would reboot and it constantly done that. I reset everything and formatted everything, I transfered the ARHD 7.0.0 back onto the phone but as I was trying to flash the image, from windows, the battery died, I can't seem to charge it.
All its doing at the moment is flashing the red LED. I tried resetting the LED with power presses in and Vol but it keeps coming back after a few seconds.
I really just need to know how to charge the phone, once its charged I will be able to sort it out. Oh and I can't even turn the phone on at the moment.
Thanks in advance.

Sounds like you didnt instal the boot.img
EDIT: put it in the wall charger for 10-15 minutes and dont touch it...

I put it in a wall charger and its stopped blinking. Cheers
Oh and I did install the boot image on Monday, i've been using the phone for two days, then it just lost the signal and then didn't work. Weird!
Thanks again!

Yeah....just pluggin usb charger and leave it for ~1h and U will see, it's charging.
Few days after buying HOX I was on a party with enabled wifi, async, gps ect. Lately this night my phone goes off and I wasn't able to turn it on. At home I plugged in charger but there was no charging led.
Yeah...thougt the new phone was bricked.
With plugged usb I just left it for ~1h and then...TADAA!...charging led!!!

Well tried charging it with the wall charger. At first the light when solid, I returned to it 2 hours later and the light was off. Tried to turn it of and its blinking again, I can't even turn it on Arghh!!

[Q] Phone wont turn on after battery depletion

I am having troubles booting my phone after the battery depletes and the phone shuts off. My Optimus G is rooted with lifeless Rom v14 and I have TWRP recovery.
So once the phone dies, I plug it in to charge, and the phone screen automaticaly comes on and the LG logo flashes for a second, but nothing happens. The phone doesn't actually charge. If I remove the phone from the charger, the display still stays on until I hard reset it. I cannot access recovery mode or download mode for some reason. Usually when my phone dies, and I plug it in, it will flash the LG logo, keep the display on for a few seconds, and then shut down and restart and show the battery logo charging. I am not getting that this time, and I can't seem to do anything to get it operating again. There also isn't a red LED light to represent charging either. If anyone has had this issue before or knows how to fix it, I'd really appreciate the information right now.
Thanks

I had the exact same problem last night. (weird) I held down the power button for ~15 sec, and let the phone sit for about 15 min. I booted it and got it to load into TWRP and then put it on the charger. Let it charge in TWRP to around 10% and then booted into android and let it charge overnight. I had a mild panic attack at first but all is good now. Stupid software dependent charging.

Ok, that's definitely weird... I came to XDA because of this, it happened to me 2x and I did the same as you, let it charge in CWM till 12% ( shower time) and reboot the system. I'm not sure what exactly is causing the issue, it shouldn't be a software problem.
To try to find what's going on, lets talk about what we have in common:
ROM: Houston stock international (stock 4.1.1)
Charger: Non LG charger (htc)
Cheers
