Hi my phone has been shutting off randomly at 20%ish for a while now and last night it shut down randomly again. but when i got home to charge it, it keeps restarting at the recharge logo and when i powered it up it still keeps restarting. I have wiped the cache partition and nothing happened.
Try with a new battery, you might have a damaged one.

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.
Turned off the tablet last night and threw it on the wireless charger. Woke up this morning to turn it on and it stalls on the boot animation. I hold down power for several seconds, then press again to reboot. It booted this time but i lost selections of data, for instance some games and a bunch of apps had to be re updated..
im running stock 4.3 rooted.
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.
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 have a Huawei P6 that randomly turns off after unplugging it, The phone actually holds the charge and take time to fully charge, also sometimes if not touched it will stay ON for too long but after plugging it then using it it will say "Random app" Has stopped working and becomes totally unusable until restart, The problem started when I tried to Download a 1GB file add to that I started downloading in the morning which means that hasn't been used for good amount of hours but it overheated and when I turn it ON it either get stuck on Huawei logo or shutdown after it, I can access Android System Recovery with no problem.
