[Q] weird battery/charging issue - AT&T Samsung Galaxy S II SGH-I777

So this morning when I unplugged my phone from charging all night, like I always do, the notification bar said the phone was still charging. I plugged charger back in and unplugged and it went away. A couple hours later, I noticed my battery was draining extremely fast. I check the battery in the Settings>About phone>Battery Usage, and it said the phone had been on battery for 24hrs. Meaning the phone never recognized it had charged. I refreshed and no change. I wiped battery stats in recovery and it seemed to work. I later charged the phone to 100% and the problem started again. Phone kept showing the setcpu charging bolt in the notification bar. When I checked battery usage, it just showed 0 seconds on battery and there is nothing there. No display time, no android OS, nothing. I decided to flash uNamed, coming from serendipity. After flash, battery usage still showed 0 seconds on battery. I pulled the battery, and then ended up in a batter charging/battery empty bootloop sort of thing. If I pressed all three buttons (vol up vol dwn and pwr) it would take me to download mode. I had to flash an odin kernel just to get phone working again, but battery stats are still screwy. Any ideas?
Edit > my phone keeps showing charging bolt symbol when its not plugged in. Got it to turn off by plugging/unplugging phone several times. While sitting in my pocket the phone made that noise it makes when you plug it in. Now my phone thinks its charging again. Wtf

[Q] Defective phone? Charging problems/random power off

This morning, I woke up to find me 3vo plugged in, but the light was off and I couldn't turn the phone off. My first thought was that it died.....while plugged in over night? So I pulled the battery, put it back in, plugged it in, and the red charging light came on, but only half the brightness it normally is. It also wouldn't turn on and the light turned off after a couple of seconds. I then pulled the battery, waited a minute, put it back in, plugged in, and it seemed to be charging like normal. I turned it on but it took a couple of minutes to boot up, much longer than any normal boot up time.
On a separate occasion, I had 60% battery life one afternoon. I checked my phone 15 minutes later and it said the battery was 5% or less and then shut down a couple of seconds after I turned the screen on.
There was nothing to link these two incidents. I'm trying to figure out if it is a problem with software, hardware, or battery. I can't make the problem happen, so its going to be interesting if I need to take it to a sprint store for a replacement/repair. Thanks for any input or ideas.
Phone is stock, no root.
I know I've had to pull my battery for unknown reasons to start it. The only time I ever so the led at half brightness is when the phone is booting without quickboot (battery pull clears memory for a quickboot). It's like putting your computer in sleep mode, your computer sends fast startup information to volatile memory (ram), so it boots off fast RAM instead of slow hard drives.
As for your 60 to 5 in 2.5 (seconds). I'd try wiping your battery stats in recovery. Make sure you have a FULL charge, wipe battery stats, fully drain the battery, the fully charge. Your battery meter should be accurate afterwards...
If this helps, please hit the thanks button...

Eh?! Photon won't turn on anymore. White LED when plugged in?

My photon was on 5% about an hour ago... then it turned itself off. I plugged it in to the charger and a "white/faint yellow" LED comes on. Normally the photon doesn't have a charge LED so this certainly struck me as odd.
It has been sitting for almost an hour and still won't turn on.
I took the battery out and reconnected the charger and the white/faint yellow LED comes back on, even with the battery pulled out.
What is happening here? Has anyone seen this?
I've see green/orange/red LED flashes for diff things but never white.
Well I found this thread: http://forums.androidcentral.com/sprint-photon/107931-led-not-working.html#post1147045
Looks like white means very low battery and charging. Now the white light has gone off while plugged in... But it still will not turn on
Turns out, I was plugging it into a PC usb that didn't have the drivers installed. The phone won't charge if the moto drivers are not installed, regardless of the light
I plugged it into a wall charger and viola... its back and running.
False alarm!
Lol, exact same thing happened to me! I totally freaked out, but plugged it in a wall and started working.
same thing happened to me yesterday. I plugged into the wall, NOTHING. I started freaking out, until I pulled the battery and re installed it. LED charge light then came on and all was good. Weird.
Can someone help me i have a photon also but when i plug it up it says failed to boot 2 starting rsd mode battery too low to flash and it wont boot up when plugged up to a computer. also when i plug it into the wall it just boot to the m sign

- Pull battery
- Put it back in so it's off
- Keep it plugged into the wall to charge it
- Once charged, power into RSD mode (power+vol up)
- Plug into computer and start RSD and flash 154_5 SBF to get back to stock
- then flash 198_7 SBF for good measure.
- Reboot
When i try that nothing works, it just stays on the white led light
I just bought mine from best buy and it did the same thing..they exchanged the phone since it was defective..

Photon won't turn on anymore. White LED when plugged in
i have a refurbished replacement photon from best buy geek squad that i got last month. within a few days it was acting strange and randomly/often turning itself off. the battery was fully charged yet the unit would often times power down. this happened a lot the first few weeks. then last week the issue seemed to stop and it stayed on 24/7 as i charged it frequently. all was well until yesterday.
i dropped my phone from about 2 feet. the phone turned off and only the "m" boot up screen appeared after i powered on, then it went black. i had a fully charged battery in the unit when this happened. i plugged the charging cable into the phone and it kept booting up to this static "m" screen then turning off. the LED notification light went red and after numerous times powering on and off and resetting the battery (and sim card) i finally got a "5%" battery screen. a few seconds later it showed 100% battery then kept rebooting to the static "m" screen and shutting off again. then i started getting a "?" screen for the battery a few times and back to the 5% and it changed to 80%/100% very quickly and back to the blank screen. i left it plugged in overnight.
now the LED notification light turned white and the phone cannot be powered on. i tried another battery without any success so that shouldn't be the issue.
any ideas what to try next?
same thing happened to me.

Try to fully charge your battery using portable battery charger.
When battery full charge, try to entering recovery mode. From off condition, press both power and volume down, press down until you find android recovery and press volume up button. After you see exclamation logos, press both volume up and down. Then select wipe data. Hope fully you can still entering recovery mode.
If you cannot enter recovery mode, try to enter RSD protocol.
step is, connect your photon to PC using cable data, press both volume up and power, wait until it show RSD Protocol, than flash it again.
How to flash using RSDLite is in development section, you can read there.
Hopefully its can work

[Q] Galaxy s 2 Battery/USB Problem?

So.. I have googled the crap out of this problem and seen loads of issues raised, but nothing solved.
I am coming from a Dell Streak and grabbed me a galaxy s 2 from craigslist a couple months back.
It has been running fine and I have tried a few roms/kernels and a few days ago I got the following error:
When charged to 100%, I get the notification to unplug, when I do, it sticks. No big deal but even when the phone battery has dropped to around 80% it stays.
It does not go into MTP mode or think it is plugged in via USB. Although, before this problem originated, the phone continuously vibrated between charging and not, when not plugged in.
I have calibrated the battery, tried a mixture of roms/kernels and I am now on unrooted stock. The problem still occurs and sometimes it does not recognise a USB connection, like today.
Probably worth mentioning that when turning on (and not plugged in) the phone does not turn right on, just boots into the battery screen and flashes between the battery charging and the overheating symbol.
Anyone got any ideas?

Turn off the phone and put it on charging. Once it beeps that its fully charged, quickly unplug the battery for 5-10 minutes. Should work and 'recalibrate' your battery

Thanks, giving a go now.
Do you need root to calibrate though? I am on stock firmware and not in front of a windows machine to use ODIN.

OK, charged to 100% and got the full notification.
Left battery out for 10 mins and whacked it back in.
Turned on and it went to the overheating sign again.
Booted into the samsung recovery and I can boot into android from there.
Battery says it is as 88, cannot calibrate as I do not have root atm.
Any ideas?

Get root and use the battery calibration tool from the market. The best idea so far. I suggest rooting with CF-Root, its fast and easy - its basically still your stock kernel but just with root.
If you really need the warranty or you'r scared of root you can install cf-root, calibrate the battery, then re-flash a stock kernel (unroot)

If i helped you, press thanks. Thanks.
Done and done.
Calibrated, even bought a new battery. Tried various other roms and appears to be an issue. Phone knows when USB is plugged in but does not seem to recognise the unplugging of the charger. And stays at 100% for a while before dropping down to like 80.
One thing to note is that this seemed to happen around the time of buying a dock for the samsung from Amazon, by Kidigi. I plugged the phone in to the dock without a USB cable connected to the dock and the dock LED lit up, making the phone think it was charging. Is this likely to have caused it/messed up the micro usb forever?
Thanks again guys!
well i think ive figured out what the problem was
Its due to overcharging or keeping the charger connected after battrey is full which has caused a hardware damage
im not sure if this is true but this is the closest explanation i can get the phone shows connected to charger even when diconnected only when i keep it connected for long time even after its battrey is full my usb connection has completely stopped working

well that the same problem with me when it shows connected to charger at 100% i restart it then the phone drops to ~80% battery although its 100% which makes the app battery monitor widget think i have a 1977mah battery while i have the standard 1650mah battery this must be the extra 20% which disappeared after the restart for me
I thought it may have been an overcharging problem, although no other phone I have owned has had this problem.
I let the battery charge all the way down (it stayed at 1% for about 3 hours) until it shut itself off. I left it on the side and it created a clicking noise, it was trying to turn the phone on as it knew the battery was in, even though it was depleted.
I plugged it in via USB to charge and it tried to turn on straight away. Shut it down and charged by plug until the 100% notification then turned on.
Still the same problem but one of my battery widgets warned that the battery was over voltage for a while before calming down.
If the phone cannot be off with the battery in, what could be causing that?

It has been known to be caused by a defective circuit board for the USB connector.
So, it needs a samsung return, I assume?
i have the same problem with overheating and usb plugged when there is nothing connected
i changed the usb port from the phone but it still having the problem!!!
i will try to put a new battery and see if it work and after post a reply

HELP! Prime won't start up.

So I took the prime of its box, plugged it into the wall and tried turning it on. When I did, the Android battery indicator screen showed up. The battery was in the red, about a quarter the way up. I've since called Asus about the issue, and they told me to charge it for about an hour. I've done that, and still it doesn't work. It still boots into the same screen. It won't even go into recovery if I hold volume- and power for 10 seconds, just back to the battery screen. I feel like maybe I'M doing something wrong here. Any ideas, guys?

it's gotta charge. mine did that too and i was freaking out. apparently not all tablets are charged. It took about 10 minutes to finally get it to boot up.
If you charge it and it still doesnt...then it might be time to ..worry
I'm only worried because it's been charging for an hour and still just goes to the battery screen, shutting off immediately after. I'll let it charge for a few hours and if it still doesn't work I'll just have to call Asus.
Whoa sorry to hear this.When i plugged mine in it started booting up & went to the home screen.It had 21% battery left on it.So i shut it down & letting it charge the full 8 hours that's recommended before even using the device.I hope yours works.
Make sure the charging light is on
where's the charging light?
its built into the power on button. a tiny little orange led
It's not coming on. When I plug the tablet in, it recognizes that it's plugged in and vibrates, tries to turn onamd fails.
Make sure it is plugged in all the way in the tablet.. and then wait a bit. you must use the wall charger.
It has been plugged all the way into the tablet with the wall charger :-/
Dang! Sorry to hear this. if it doesn't come on within the hour id say just exchange it. it might bea faculty unit. it should have enough juice to boot up by now considering if you charging it properly. Good luck. wish it was working for you because this is a great device.
I am having the same problem too when I first plugged it in the battery indicator screen came on real fast and turned off the orange charging light came on and turned off.I tried plugging into the computer it does nothing diffrent.I think it might bricked.
okay. i just got my primetoday, same deal. it doesn't start, tried to reset, etc. i finally charged it for a while, after a while, it finally boots. at that point it was at the 15% battery life mark.
seems a bit odd.... i would wait and see.. if its game stop they would of had games installed on it.
I just got mine today...woot!!! But the issue that u have happened to me also what it happened was a faulty charger

I tested the charger on my phone and it worked. I plugged into the tablet and pressed the power button the led came on and blinked and turned off quickly.I think the battery needs a good charge.
I had to charge mine until the battery indicator was green before it would turn on. Said in the manual to fully charge before using for the first time... so maybe it doesn't let you start up until charged?
Well after 3 hours of charging it finaly started up but the battery level was low 3% showing that tells me the battery had no charge in it.Well I am happy that it is working and hopefully no other problems show up.
Good to hear
Same exact thing happened to me, lol. Mine arrived with zero charge and I just let it sit for about an hour plugged in and all was well.

Ran out of battery, can't boot phone

Today I ran out of battery ( I plugged the charger when the phone was at 2%, but it froze). I turned it off, and the battery charging screen showed up. Let it charge for a little while, tried turning it on, then froze at Samsung screen. If I turn it off it, turns back on and freezes at the same point, and thus a bootloop.
I can enter recovery and it says that battery is at 20%. What's wrong?
I went into recovery again and it says 37% now even the battery charging screen drawing looks like it's good way less!
just let it juice up for 5 hours.

Nevermind, it was a coincidence with this damn LS8 bootloop bug: http://forum.xda-developers.com/showthread.php?t=2126442
factory reset then.

yup, it was fixed by doing that. I'm charging it to 100% and going back to LSJ, I'm done with LASS8.
