I was using my S7 edge yesterday alongside the G5, and at 70% battery left, I had a SOT of 1 hour, 5 minutes on the S7 edge. At 70% battery on the G5, I had 59 minutes SOT. I couldn't believe how close they were.
I like reading that, I dislike face buttons which is why I picked the G5 over the S7 and my only potential regret was battery life of the S7.
I'm even happier with the selection now, thanks.
