I bought a LG V30, NEVER LG Again, but in the middle time because my MOTO Z is not my primary phone, I tested all ROMs, AOSP, Remix... ALL THEM, I did a clean install then used for a week. BY FAR, REALLY FAR, ErfanROMM 7.1.1 is the best, using this rom with TurboZ kernel and battery mod, I got the phone running (With my normal use) for 4 days.
With OREO, for example on the same test scenario, never passed the 2 days

Is there a version 4 coming or any rom updates?
