I don't know what kind of magic was in that update, but just wow!
My battery life has improved by 30%. 1st time off the charger with the update I was at 70 hrs with still 11% battery left. I probably had about 8 hrs of life left.
2nd charge, currently I am sitting at 76% with 22hrs of use.
The real kicker, I am getting better battery life on my S24U. This is my battery after 7.5 hrs of SoT.
