S4, a few months after launch day, 93% with optimized charging. Still getting S7 and keeping my S4 as a backup.
My daughter’s S4, on its launch day as a bday gift for her, is at 98%! But she did not use it as much as I am. I am using it 22.5/7/365 especially for health monitoring and metrics. I charge it completely before bedtime and use it all day and night long.
I cannot wait to upgrade to S7 because I upgrade for all the new features, even though the battery life is still young.
