Ever since lollipop came out my phone lost nearly all performance. My old phone LG Optimus G is faster than my LG G3 with lollipop. The battery was at 50% then my phone just died like 2 hours later Web surfing became super laggy and the WiFi will turn off by itself and even when on won't work all the time... This is unacceptable for a fairly new phone that I've had less then a year. Let me go back to kit kat when my phone was unstoppable.
