Charging phone with power off

Is there a way to charge the phone while shutting it off? I used to do this before I rooted cuz it charges faster but I flashed ics now and when I shut it off and plug the power cable in the phone automatically turns on. When I turn it off with the charger connected the screen shuts off but keeps going back into recovery

I don't remember a single moment on DZ flashing history that enabled me to charge the battery while the phone was off. Something I was also expecting too. I don' t think it will happen since it might be a hardware level feature, could be wrong though.

Have you tried plugging it in and *then* turning it off?

CWM recovery has this bug, that when charging while off, it will automatically launch... just keep it this way for a minute, the screen will automatically turn off by itself... or flash 4EXT recovery (like i did)

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.

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?

Battery died then phone won't boot

So as title says my wifes battery died then once plugged up and left to charge phone wouldn't go past boot animation. she was running beastmod 5.0 and had been for Weeks without issue. It would boot as normal but as soon as the animation completed it went to a black screen, screen was lit up just black with darker black blotches. Has this been encountered b4? Any known cause?
Luckily I was able to get into recovery and restore a nandroid and it seems to be ok now, but I'd like to know wth happened .
Thanks

Maybe the battery didn't charge. But the phone booted and did not turn on touch screen or any type of resource that controls touch input. This has happened to me, I ran out of battery, 0%, and then I plug it up, it turns on but it doesn't not turn on any touch input device. So, I had to wait until it had 5% of battery to boot it up. This is the only issue I've had close to that

Once it died it sat on the charger for about 4 hours and one I restored a nandroid it was at 78% charge. After the boot animation it was just a back lit blotchy black screen, no wallpaper, notification bar, icons or any remote sign if life

So, is this fixed or you still having issues? If it is not fixed, pull battery, unplug, let it sit for 2 mins and (clean contacts if needed on batt and phone) and put batt back in, plug it. Let it charge for good 4 - 5 hours (don't power on). Unplug it and power it up. see if that fixes it.

[Solved]Red led light ,phone won't turn on

Well yesterday I flashed P.A.C Rom and when the device battery was on 0% the phone shuted down and after that I connected it to the charger to charge it again but I have a red light and the device doesn't reacts. Tried to to hard reset and everything but It doesn't helps.
Please help

I had this problem as well. You have to wait till your phone turns on (takes 10-15 mins) and boot into recovery. Flash another kernel with offline charging and it should work from there

Can you explain please which kernel should I flash?
Phone boots for 5 sec every 15 minutes and then it turning off again.

if you drained the battery during flashing to absolute 0% then it wont turn on immediately when you plug in the charger..wait for about 30minutes before starting the phone again..and dont flash when you are low on juice..always keep at least 50% battery :good:

Ok ,everything is ok now. I had another replacement battery so I used it and flashed stock rom on the device. After that changed to the original battery again and charged the phone offline.
