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.

[Q] Automatic wake up when connecting power or USB

I'm running Nova and CWM9 and whenever I connect the phone to USB or a charger the phone wakes up automatically forcing me to push the power button evey time I connect it to turn off the screen.
Anyone know if it's possible to disable this "feature"?
Thanks!

I believe stock does that too. That would be an interesting tweak if it's not already around! In terms of disabling, I'm not sure there is an option to do so.
Sent from my GNex running gummy v0.7.0

Confirm stock does it as does Apex; presumably it's set somewhere basic in ICS

Its in developer options. Untick 'stay awake' (if I understand the question!)

And this is a problem why? Its just indicating to you that its plugged in properly and charging... the screen will time out and turn off a few seconds later.

Thanks for checking!
It is interesting that Google would assume everytime you plug the phone in (and unplug the phone) you would want it to wake up. Considering the short battery life these phones have, lots of charging would be commonplace and therefore lots of connecting/disconnecting without the intent to actually use the phone.
I could see giving people the option to have the phone do that - but for me the unplug wakeup is especially annoying because I have to turn it off everytime I go to put it in my pocket.

Well considering by stock there's no charging LED indicator, turning the screen on momentarily to indicate a charging state is a smart idea.
Also, if you're plugging it in, why are you worried about the battery drained by keeping the screen on for 10 seconds? 10 seconds.

Well that's that I thought too, but sometimes it doesn't go back to sleep like it should and I'll notice my pocket getting quite warm pull it out and it's still on.
It could be a bug in the ROM I'm running (not going to sleep correctly all the time) but I don't remember my DINC doing that so I figured it was something that just needed to be disabled.

Hmm, I did have this option enabled - mainly because when I connect it to the charger I do like it to stay on -prime example using Slacker Radio in my car when plugged into the dock.
Maybe I'll try a different ROM since it seems the problem isn't so much that I need to disable to wakeup on connect/disconnect but instead I need the sleep function to be more reliable so I don't have a mini oven on my pocket.
Thanks!

A great option for your car dock needs would be to introduce something like the app Tasker. Then you could leave the screen off but have tasker set it to constant on and load slacker when the Bluetooth connection to your car happens.

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.

[Q]3.0 EMUI battery issues:

Hello everyone. I am new rom 3.0 and I really like EMUI 3.0 . But there is one problem here: my phone when battery low alarm, it quickly dropped to 0% and power off after a few seconds. I only have a problem when using EMUI 3.0 b709 B708 - problems previously with 2.0 rom not available, the device indicates a low battery after charging plug is operating normally. So how can I solve this problem?
Sorry I did not know English - I use google translate.

happens to me, really too annoying. discharges by 15% of the battery to 0% in 1 minute. Help

Likewise with me. My battery still dies, even when I plug in the charger at 8%, on B708. Not sure how to fix it, but hopefully it will be fixed with the next update from huawei.

Hey you! I have solved the problem DC - you can try it. The steps I resolved as follows:
1. My phone has root. Note the red phone battery, then delete the file using File Explorer File /data/system/batterystats.bin (red battery icon when new deleted - if you are not root can try to skip this step).
2. When the device indicates a low battery will turn off within 30 seconds - let's quickly plug the battery charger. To shut the phone off - and then automatically into charging mode when turned off. If you see the battery starts charging from 0% is ok.
3. Leave the so wait until the battery is full, the battery indicator light turns off. Keep the charger cord - turn the phone on and then unplug the charger is.
END.
My phone will not power suddenly collapsed again. Good luck

t's weird. Are you sure you plug the phone before charging up the power off? And the phone starts charging from 0% in the off?

phone won't turn on without charger plugged..

Hello everyone i got an Optimus g pro e980 with a custom rom downloaded from here ( i had the same problem on original firmware.. )
if i pull battery out for example or simply just turn off the phone.. i'm not able to boot it again without plugging the charger and wait for the battery charge icon..
i think the battery has some problems as.. sometimes.. form 68% when i turn off the phone it shows 10% or lower...
i also have some random reboots some times.. it may be the battery?.. screen also flickered for a minute but not has gone .. thank you.

Which ROM are you using? Screen flickering can be fixed by turning off the hw overlay in the developer's options. As for the battery, try get a calibrating app from the play store, else get a battery repair app to see if your battery can be fixed. My OEM battery is broken, which causes random reboot since it supplies power intermittently.

Your battery is probably dead if it looses capacity like that, replace it as soon as possible.

Can't tell about random reboots if no logs, can be anything with this phone. Mine likes to reboot because network changed from LTE to H+, or just out of sheer 'I wanna mess with my owner, for no reason at all' Because annoying the owners with bad temper is good for business
For screen flickering - do as hawkwind212 said, or try with other ROMs (I'm guessing you're using CM if you suffer from those)

Stock rom xD .. also tried using a custom rom... i tried using a 1200 mAh and force the phone turn on... and.. it worked.. so the problem may be the battery.. and not the phone idk tho...

i wanted to know if the motherboard from other models (98x) it would fit with my current model.. i mean.. the touchscreen and other things.. to work properly.. some people said that any 98x version would work but idk ...
