[Q] Battery dead - LG Optimus G (International)

My phone turns off at 50% (sometimes it's 12% or 60%) and I can't turn it on. It says it is empty and needs to be charged. I tried everything from calibration,wipping everything in recovery,bbstats, different ROMs and even went back to stock and still the same. Any help?
P.S.: Before this all started the phone was in customers service and the back of the phone isn't put as it used it's moving, does that maybe move the battery or something like that?

false full battery with random boot loops

I have this problem: youtube.com/watch?v=chvRbwgT9n8
Sprint Galaxy S3, unrooted, stock
Basically one night my phone would not turn on after the battery completely drained out. Put on charger but phone would not turn on. Did the spin test on original battery and it seemed busted. Ordered a new battery, put it into phone, charged for a couple hours and have the same problem the above youtuber does. The battery icon looks identical (both the grey and ~90% one).
1) If phone is unplugged nothing happens, can't start into recovery/download/boot.
2) If phone is plugged in it will show grey battery icon for like 10s, then go to a green battery screen where it shows the battery is ~90% full. The red charging light stays on.
3) I can boot into recovery mode if the phone is plugged in but if I try to normal boot the phone it will 50% get to the S3 splash screen, vibrate, and then turn off, and then 50% of the time it will boot to the home screen but wifi and data will not work (the battery icon will show 100% at this point). After a few seconds the phone will vibrate, turn off, and return to the grey battery icon swirly and then back to the 90% green battery screen.
4) I've tried wiping cache and doing factory reset but doesn't seem to phase it.
5) Reflashing via Odin to stock doesn't fix issue.
Any ideas? It doesn't seem like the power button issue because usually in those cases the battery shows as low or it will be stuck in a constant repeating cycle. This just seems like the phone is not drawing any power from the battery. Thanks.
Update: so it appears that the longer I leave it on the charger the longer I can use it while connected. The issue now is that Wifi and data will not enable, sound intermittently works, bluetooth doesn't work. I found someone else with _exactly_ the same issue and symptoms who had a weird fix:

OK, Czech this out, I took my sim card and SD card out of the phone and tried to start it, and guess what? IT FREAKING CAME ON!!! It obviously wont function without the SIM card, and it prompted me to turn off the phone and reinstall the SIM, but after doing that, it started right back up like it was new.SO EVERYONE GIVE THAT A SHOT. We'll see if it gives me any issues.

The problem for me is that the Sprint version doesn't have a SIM card and I'm not using a SD card. Is there any reason for this madness?

[Q] [q] Hard bricked? Won't turn on, won't connect, small signs of life

Hi,
I turned my phone off last night before going to sleep, it had 40% battery left. When I tried to turn it on this morning it didn't do anything. Even when trying to charge it the LED did not light up.
the only sign of life I got out of it was a screen with the "battery charging", looked like it was charged around 50%. However, it did not, and still does not respond to the hardware keys...
Any solutions? Or am I simply out of luck.
Extra info:
Stock rom, rooted.
Already had some sort of problem described in this thread: http://forum.xda-developers.com/galaxy-note-2/help/phone-freezes-awake-stock-custom-rom-t2908503
Thanks in advance!
May be you should try wiping data (lock screen & stuff) from samsung online site (if you have registered).. Not sure if it work.. Just a suggestion..
Somehow I don't have any registered devices.. (I did register it though, just because of the dropbox storage bonus)
Edit: My device randomly booted up, had it plugged in to the charger all day (about 6 hours), 47% charged right now.
going to make a backup using titanium and flashing stock via odin, see if it helps.
This is reaaally weird though... :silly:

Do I have a bad battery too?

1. Bought it used - c6502. Phone arrived with around 10% battery, everything looked fine and then it kept shutting off every time I tapped the camera icon. It was on android 4.4.2
2. Charged to 100%, after hard resetting (using the button next to the microsd slot) couple times, it finally turned on, updated to 4.4.4, used it whole day without any problem and then google play services, xperia home, camera common or something simlar and whole bunch of craps stopped working when battery was around 20%. Phone was STILL on. So I turned off the phone and can't turn it back on now. Tried the hard reset button, Sony & the xperia logo show up, then I see the gray screen only. The on screen charging indicator shows around 3 bars which should be good enough to power up the phone, but it doesn't turn on! I'll let charge it fully and try again.
Can a bad battery stop all these services? or is it a software issue? As I said the phone was still on when all these services started crashing.
After reading some other threads, it feels like some kernels have battery drain issues ( I even don't know which kernel mine is running, used it for a day only). Should I try to flash a different kernel? Could you name a few that don't have battery drain issues? Or should I just get a new battery?
Thanks!

Last night my M7 turned off to "rest"

I have no idea why some person thought it was a good idea to program a feature to turn your device off randomly. My one year old woke me up this morning early, I went to check my phone to see what time it was but the screen wouldn't turn on.
I left it on my nightstand with well over 50% battery when I went to sleep, no apps running like usual. My device will lose 3-4% battery over night, so no big deal at ~50% battery overnight.
Continuing with the issue, I booted the phone up to see if the battery had drained or something but it was still at 50%. After it fully booted a message popped up stating something to the fact of:
"Wondering why your phone turned off? It was turned off to rest. Your phone needs to rest to continue operating at optimum levels. Using high draining applications like navigation and video streaming can hinder system performance"
Or some kind of BS like that. I wish at 3:30am I had the forethought to screenshot the message...
Has anyone else had this happen? The thing is, I barely used my phone all day. Literally a few minutes of talking, few texts, took a few pictures and browsed a few articles using chrome.
I rely on my phone for my alarm so if this randomly happens that could be bad if my daughter sleeps in!
BTW, I'm running @santod040 stock rooted 5.0.2 full version.
Mine has done the same a few times since the OTA. I'm 100% stock
Nice when you rely on your phone for an alarm, right?
Have same problem. Has happened about 3 times since lollipop update. Fully stock. I tried cache wipe but that hasn't fixed it.
I am 100% stock as well, unrooted and S-ON. This has happened about once per week. Phone shuts down by itself and displays a message upon restart (see attached).
I've asked HTC support and they've had me try safe mode and wiping cache partition, though it sounds like it's a more widespread problem than something caused by a third-party app.

Phone turns off randomly with low battery warning

Hello everyone! Recently my Note II started to behave differently. Whenever I charged it completely, the battery abruptly fell to sometimes 60% sometimes 40% immediately followed by low battery warning indication and shutting down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon as I put it idle it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery
