[Q] Q Charging while phone if off - Galaxy S II Q&A, Help & Troubleshooting

I have galaxy s 2 with miui and that won't charge when off, which is not good when battery totally drained, as now can not charge phone
had to buy 2nd battery?
I read this is a FEATURE of CM7, is this correct?
Do I need stock rom to be able to charge a drained battery?
any other options? could buy external docking charger I suppose

Which rom are you using? Not to familiar with miui but my phone charges while off with CM7 and miui is based off that.
In fact ive never had this issue maybe it is rom specific or your using a cheep unofficial battery.

Using original battery, something to do with cwm as if downgrade it charges again, but is worry as download mode wont work if battery too flat.

I had exactly the same problem with MIUI. It seems like it is ROM-specific. Now I am on CM 7.1 and it works fine.

Galaxy S2 fails to start

After upgrading to cyanogenmod 9 RC1 from a previous nightly, at some point the battery was fully drained. After that the phone refuses to recharge or even to show any vital sign. I've changed the battery and the charger, and nothing.
Anyone encountered such an issue?
Anything guys? Any chance anything will get it to work?
Turn off your phone and fully charge it after that go to odin mode and flash stock rom then root and flash cm9

The phone worked fine for like 2 weeks or so. And as for the recharge, it's not recharging at all, even the battery does not get slightly hotter.

Bricked over night

My dad went to use the tablet this morning and its somehow over night gotten bricked. All it does is when its plugged in the orange light flashes. ADB still picks it up but no commands are functioning. Please help i desperately need it.
Can you access the bootloader?
He neglected to tell me that the charger wasnt completely plugged in...as soon as i had it plugged into my laptop for around 5 mins i pushed an adb reboot command and it turned back on.
Thanks anyway bro!
A question then. Is it dangerous to empty the battery or what? Is it cous of the cwm not charging?
And why did you have to reboot it with adb?
I have flached a custom rom on my fathers flyer 3g. Should I be scared for the battery?

As far as I know, people don't recommend to empty the batteries from 100% to 0%, better let it discharge to ~8-10%? and plug it in and let it to either charge fully, or somewhere to ~90%.
And no, you shouldn't be scared, flashing custom ROMs won't kill your battery, it's software, not hardware
See I was tryin to reboot it with adb because I was under the assumption it was soft bricked.

What Im a little bit scared of is when battery goes to zero I cant charge it any more. I read some where about flyer not charging because cwm had a flaw but battery then goes to zero i have to change the batter physicaly.
If that is not the problem, why is it best to not decharge battery ?

Battery Problems

Ok so phone doesn't charge as fast as usual and while charging and using it loses battery percentage and never has before. Also when I get a full charge then unplug it goes straight down to 12%. What do you guys think.... Battery or port problems?

The only way to know that answer is to rule out possibilities. Try different batteries and chargers.

I just bought another battery. I found it was the battery more than port problems or anything like that. My friend and I have the same phones, same roms. We tested this by first going through 3 power cycles. After we charged it, we had only the same apps working, except for some minor checking of FB and twitter (I don't use twitter, but he does).
After our 4th power cycle, it seemed like his phone was dying faster w/ my battery in it. His battery in my phone lasted about 5-10 hours more, I did my normal daily activities on it, even played some youtube videos in class.
So I bought a new one, and bam, stays alive more than 12 hours

I also had the same issue in my i777. i changed OEM batteries and doesn't work. for me it was the PORT.
i ordered 1 from ebay and replaced. now its work fine.
please change the port. it will work perfectly
work around
i am using super nexus rom battery life is great compared to stock.
try tablet charger if you have. it will charger your phone faster. i am using my nexus 10 charger its definitely taking less time to charge.

Common sense post of the day:
You have to be really careful getting phone accessories off e-bay. In the past I've been duped into buying a fake SD card and a wonky battery.

flashing ROM without battery

is it possible to flash this phone (Atrix 4g) without a battery and only the wall charger connected? i've did some search and couldn't find anything specific on this phone but it seem like its not possible to do so on android. maybe i'm wrong cuz today i was having some freezing problems and i did a battery pull but before i reinsert the battery out of curiosity i connected the wall charger and booted into recovery. of course i didn't do a wipe and flash to test it out myself since i don't have the time for all of that but i got into recovery without the battery. is that normal and does that mean you can flash a rom without a battery?
I think so... but be warned that any energy fail will lead to a possible brick of ur atrix

i wasn't actually thinking about doing it but it was just curious if its possible.. curiosity got the best of me..
you made me curious, so I did a small test with a gapps, and it worked without battery xD

good to know it works. thats great. now no more worrying about battery when flashing a ROM (sometimes i'm just too impatient to wait till my battery charge to flash a new ROM. we all know that little feeling we get when a new ROM comes out)
now i can just leave my charged plugged in with the battery.. if battery fails the wall charger should continue.. all my electronics are connect to a backup battery so i don't think i ever have to worry about the wall charger losing power. those battery go for 2 - 3 hours
I don‘t think so!don’t do this

[Q] Charger and battery?

Hello I have ordered this phone despite the fixed battery, but I do have a few concerns. Coming from a droid 2, the phone could not charge a dead battery for some strange reason so I had to use an external battery charger.
So my question is can a droid RAZR charge a completely dead battery with a generic micro-USB charger?
And has anyone had any battery problems?

Yes - this phone can be charged using a generic charger. I have had this phone for almost a year and a half, and I've used countless chargers on it - all worked. Now, I dropped my phone in paint, which killed the microphone, so I did a warranty exchange for a refurbished model. My previous one worked like a champ - no crashes, excellent battery life, etc. The replacement is still working great, only I have to charge it a few times a day. To fix this I ordered a replacement EB40 battery off ebay and replaced the non-replacable battery. It wasn't all that tough, and now the battery lasts days. I felt like I got a new phone all over again!
Anyways - long story short (too late) - the battery holds up exceptionally well, you can still force reboot if/when necessary, and you can use any charger. And, should the need rise, it IS possible to replace the battery so long as you're brave enough to open up the phone.

This man speaks the truth about eb40 replacement every $ is worth it

You should also consider getting a "factory" cable. They're specially configured to bypass the battery so that you can access the phone even if the battery is dead. The bootloader won't charge your battery.

To answer you question, no, you can't charge a dead battery unless you have a factory cable, which is wired a bit differently than the one that usually comes with the phone. It is wired so the phone can bypass the battery and get the juice straight from the cable, which allows it to go through its whole boot up sequence, in turn allowing it to begin regular recharge.
I've had some battery issues very early in my phone's life cycle. It would sometimes, out of the blue, turn itself off, as if the battery had reached a critical state, but I can't quite remember what I did to fix it, sorry.
