Believe it or not, the Edge + is lasting a tad bit longer than the G4 during my everyday use. I switched 2 weeks ago and I can tell a marginal difference in battery life. The quick charger helps. It does bring my battery back to above 50% within about 20 minutes. LG should have included a quick charger. To be honest though, no Android phone even comes close to the amazing battery life of the iPhone 6+. I'd go two days on a single charge on that phone.
Like I said, I had the International Version of the G4, so I know how it should act and respond. My brother-in-law has it now and it works great. It just doesn't work on Verizon. Also, this is my 3rd LG phone from Verizon. All 3 had issues prior to receiving updates. The G2 took 3 updates to work out the kinks. The G3 took 3 updates to work out the kinks. I didn't feel like sitting around waiting on the G4.
