Charging phone with power off - G2 and Desire Z Q&A, Help & Troubleshooting

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)

[Q] Clear battery stats ISSUE. Read

I installed the DK custom rom yesterday and today i reset the battery indicator.
# Power off the phone and fully charge it until the led is green.
# Turn the phone on for a couple of minutes until the battery indicator drops from 100% to 99%.
# Power off the phone again and charge it again while watching. As soon as the led turns green proceed to the next step.
# Unplug the charger, boot the phone into Recovery mode and reset (or wipe) the battery stats (on advanced menu in ClockWorkMod).
# Reboot and continue to use as normal.
Ok, now however the battery indicator says me always 100% of battery life!!!
And this is not good at all. What i should do?
how long have you left it? mine can stay at 100% for quite a while before dropping, but after that it drops rather faster
Problem still there? Tested it and have no issues here

Its a Clockworkmod bug, and, there's no workaround. Actually, when charging the phone in the off state, it wouldn't turn on, and the battery had to be removed, but, the workaround to this was to turn on using Power Key + Vol Down.
how can we recalibrate the battery with the clockwork mod bug?

[Q] USB death after Root and Flash on Xperia ARC

HI all,
I flashed my Arc last night, and then rooted it.
All seemed to be fine, until I rebooted after the Root had been completed.
Once the phone turned back on, the battery had dropped from 70% to 1%. It was warning me that it was about to shut off, so I tried to plug it into the computer, via USB cable to charge, and nothing!! I thought it must just be my computer, so I tried to plug it into the wall socket, and still nothing! It just refused to charge. Full stop. However, it continued to tell me that I was bout to run out of charge and didn't turn itself off!!! I unplugged it 1000 times, and still tried each option ( computer/wall socket) and it just wouldnt work.
So, basically, this is a well known problem and you can solve this by following this procedure -
" try removing the battery for a few seconds then reinsert the battery whilst the wall charger is plugged in. give it 5 mins before attempting to switch it back on.
if it manages to switch back on, try to put the phone in flight mode until the red light turns a pale green. "
I did this, and turned it back on. Straight away the phone rocketed back up too 77% battery.
And, the usb port worked again.
So my question is this,
Is this a common issue?
And is following the above process ok for the phone? I hope that I wont have to send it back, cause the other people on that link above had too.
Is anyone else had this problem?
Thanks all for your input
Amanda
This is a common issue, no worries Amanda! Same for me when I flashed the UK Generic 2.3.2 to obtain Root..
How did you fix it???
This happened to me also last time after a reflash. You may try to do a complete drain then do a complete full charge (don't turn on the fone while charging at this time).

Just remove the battery and wait a few sec.

Battery issue

The other morning I woke up and unplugged my phone and the "Unplug your phone" notification wouldn't go away and the phone thought it was still plugged in. If I rebooted it would just turn off and keep going from the green batter charging icon to a black screen and back. Only way I could turn the phone on would be to actually plug it in again. Problem fixed itself that evening and the phone was fine for a couple days. Today the phone started with the same thing.
I've tried searching but couldn't find anything on this specific issue. Any insight? Thanks in advance.
Brand new ept4g and I got 6hrs of battery life its so lame I have hack so much bad luck with this bad boy but I'm not giving up.

I'm having the same problems the last few days. Also when I unplug my phone I get a red exclamation point over my battery widget, when i open the widget it says that the battery is over voltage and the red led light won't go off. Think i'm about to go see what best buy does for me. Been dealing w/ this problem for a few days now.
Did you get a replacement? I haven't had any free time to go to sprint with my problem. It is still happening often though.
I had a similar issue the other morning. Though my phone would only boot back up in recovery mode. I reflashed it to out of the box stock but that didn't make any difference. When it did boot up it would show that it was connected to the usb port but it would not be plugged into anything. I plugged it into a usb port on my computer that I hadn't used with the phone before and it reloaded the drivers on my computer and "that" issue went away. After turning phone off it would start rebooting itself immediately or with in a few seconds of turning off. I let the battery die completely and then recharged it and the automatic reboot went away, at least for most of the day, but last night I turned the phone back off and it rebooted itself. I did reroot and restore my phone after I got it to not show the usb connected or the battery charging while the phone was off icon. Just wish I could figure out why it wants to automatically reboot itself when I shut it off.

My Battery Monitor Widget shows a max of 1500mah? Wtf? And a measured of under 1200?
No wonder my battery life is crazy low...

I figured a way to shut the phone off and not have it automatically reboot. If after shutting the phone off the normal way and once the screen goes black but before the capacitive lights go out, if I again press the power button, the phone finally shuts down without rebooting itself. Not sure why this is happening but at least I can get it to turn off now.
I found better battery life by determining which app or apps drain the battery. I used Battert spy, cpu spy and system tuner. My problem was Touchdown exchange for Androir 2.x. I switched to Moxier Mail. I would get hours on moderate to heavy use. I got 22.5 hours yesterday on moderate use.

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.

[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
