Okay so, my LG G3 has had a problem with restarting and bootlooping before this. Basically, it would restart if used while not plugged in and would not boot up if not hooked up to a charger. Before this, plugging the charger in would solve the boot loop issue, but now, that leads to a different issue.
So, I was using my phone (while it's charging) and suddenly - screen goes black. After a few seconds, the battery loading screen (an icon of a battery with a small circle with several spokes in the middle of the battery icon) pops up. I hold the power button and the LG logo pops up and then goes back to the battery loading screen. which just bootloops if left alone.
Now, the phone CAN boot into recovery and bootloader (although it sometimes fails, it's like the device restarts mid-way through). In TWRP recovery, it shows the battery at 100%, although after rebooting into recovery again after some time, it displayed 75% (i never took the phone off the charger).
Sometimes while in recovery and the device is not plugged in, it'll restart, but that's kinda... normal, I guess, it used to do that before.
My PC recognizes the phone and I can access the data on it via USB without any problems.
I'm almost positive that the battery is the culprit, since a few hours before this started happening, it drained 20% in 5 minutes and in general, after it restarts randomly when not charging, the battery goes from 100% to 90% and if restarted again goes back to 95% or something like that. But does anyone have any idea how to fix this? I won't be able to buy a new battery for a few days and I need the device in working order until then.

I've seen this same behavior twice. Once yesterday and once today.
Yesterday
Phone was plugged into usb port of laptop charging (around 50% at the time) was running Pandora and Wifi Tether (build into ROM). Phone crashes to off, no reboot attempt. Attempt to power phone back on yields no result (no lights, no screen ... nothing). Remove battery for 10-15 mins, insert and hook up to a AC charger and hit power button. Red light starts flashing, I wait for it to turn solid and try booting again. This time phone turns on and hangs at white HTC EVO splash screen. I then boot phone into custom recovery image, clear cache partition, and reboot. Phone boots ROM fully, batter reads 50% still and works fine until the next day.
Today
Phone was plugged in running Wifi tether, but not Pandora. Same behavior in crashing, removing battery, hooking up ac charger etc... this time however it didn't hang on the HTC EVO splash screen, and boots the ROM. However, the battery no reads 0% and wasn't charging. Removing the AC charger causes phone to shutdown. Reboot rom again, still read 0%, but let it sit for a few minutes and begins to charge. Appears to be charging fine and holds its own without the ac charger. **Note - battery was also around 50% or so when it crashed out
Questions:
Whats the root here? Bad battery? Bad rom? Thoughts on root cause would help if anyone has gone through this.
Thanks!
I'd say a combination of battery and ROM. Try flashing a new ROM and if it continues, try a new battery.
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
My 12.2 keeps crashing and ending up in SDCard Mode.
It works just fine after charging. I can boot up for a day or two, the battery seems to discharge normally, then I will try to boot up and it goes straight to SDCard Mode. Last night I was using it, the battery at about 70% and it crashed. Black screen then tried to reboot and it goes into the SDCard Mode.
Once in this mode I can do nothing with it. No response and if I shut it down with the button it lights back up into the mode after a couple seconds. It will not charge.
At this point I either have to leave it until the battery goes completely dead, then it will charge, or remove the back and disconnect the battery, plug in the charger and when the battery shows on the screen I can reattach the battery and it will begin to charge.
With both of these options once it starts to charge it shows that the battery is completely drained and starting at 0%
Anybody know what's causing this?
Thanks,
Jim
Today with 80% on battery I started some updates off the Google Store and the tablet crashed to the SDCard mode shortly after.

My LG G3 had recently bit the dust, rebooting a couple of times with the battery level jumping before refusing to turn on. Before this, and now, if turned off and charging, it will continuously boot to charge, then turn off, only to repeat.
Now trying to boot brings up the LG logo for about a second before it shuts off and tries again, trying to boot into recovery shows this same issue. I have tried to use this guide here http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ However when ever it gets to the "Waiting for reset 20 sec" stage, it reboots, starts to charge, then shuts off only to repeat.
Any advice, or is it dead?
I have charged the battery to 100% externally before attempting this.
I am having problems with my HTC 10. This morning I charged the phone but it told me fast charging isn’t working so it was charging slowly. By the time the charge got to 20% I decided to unplug the charger from my phone and switch it on.
When I switched it on I expected there to be 20% on the battery but instead it was only 1% charge left. The phone then switched itself off so I connected the charger back to the phone but the phone switches itself off halfway through the boot and I notice sometimes the battery charge icon appears then goes off. I also notice the red light on the top of the phone flashes then goes off.
I then switched the phone into download mode and selected TWRP to factory reset the phone. I rebooted and it goes into Android and I get the message that it’s starting android as if I am booting into a newly installed android.
The phone then switches itself off when it’s halfway through loading android. The strange thing is that the phone stays on when it is in download mode. What could be the problem? Please advise.
The phone has now switched itself off from download mode probably because the battery is dead. It looks like it’s a connection problem with the charger or the battery is needing replace because when I connect the charger to the phone the red like on the phone flashes for a few seconds then goes off then the battery charger icon appears for a second briefly then it switches itself off and nothing happens. Any ideas.
