Here's one of mine from yesterday
Went with a 48% one because it's close to 50% for easy math. I was at 3 hours SOT and so 3 × 2 × .8 = 5 hours on a charge plugging it back in at 20% or 6 hours from 100% to 0%.
That seems low until you look at the other number, because that was over an 18 hour period. Same thing, 18.5 × 2 × .8 = 29.6 hours, meaning that without going down below 20% the phone can give me 5 hours of SOT over the course of 30 hours. Or if I hate my battery, 6 hours screen on over the course of 37 hours.
YMMV
