The phone start rebooting unexpectedly & continuously, it won’t turn on unless i plug in the power, & mostly will start rebooting again if i remove the cord!!

I had an lg g3 with this same issue. Replace the battery, they tend to do this when bad

When I plug my phone in it will optimize apps and wont let me on the phone when it is unplugged ,it just keeps restarting, when it finishes optimizing the apps it will let me on the phone but when I unplug it is does it again.

Look im having the same problem but my phone wont even turn on even when its on the charger i would try to hold the power button , hold all the buttons (power button, both volume buttons) and the power button with the lower volume button but still wont fix it i think you might need to change the battery or get a new phone.. i know i couldn’t give you an exact answer you needed but thought I could try and help.

It is bad battery buy new and change it

My lgk10 continuously rebooting can this happen due battery also

Change the battery it could be bad or check power management IC
