After complaining to LG customer support about the horrible battery life, overheating, and slow charging with Lollipop they gave me the expected answer that there is no way to revert to previous firmware, there is no update coming, and my only recourse would be out of warranty repair. So I spent hours yesterday going through the routine using LG flash tool and changed the firmware to 4.4.2 and battery life is as good as new. It took hours because there are so many broken links, fixes, and workarounds. It seems like LG is not the only manufacture with Lollipop problems. It is inexcusable that I had to jump through these hoops. Moving forward, I'm not sure what my next phone will be; do I avoid LG, Android, Verizon? I have no desire to have to deal with this crap again.
