I would wait. My G4 battery life is much worse than it was before this update. I can't stand it! I used to go all day, with medium usage and by 6pm, still have 30-40% battery left. I monitored it closely yesterday and by 6:30, I had 14%.
It's like every time I turn the screen on, the battery has dropped a percent. I wish I could revert back to Lollipop. None of the "upgrades" with Marshmallow are worth the horrible battery life.
On top of that, the update in November (Verizon VS98613B) had finally fixed my issue where Gmail would not sync automatically on WiFi. Whatever they changed, suddenly my emails were coming in real time. Now...I'm back to having to manually refresh my inbox, where I'll get a bunch of emails at once with time stamps from hours ago.
Really hating this update.
