I'm doing a low to medium usage test with Bluetooth, Location Access on High accuracy, WIFI, HSPA,Auto Brightness and google now. From 100% down to 0%. Then doing a Full charge time with phone turned on.
Will be posting screenshots via dropbox below with a few hours in between.

19hr screenshot with 7.5hr overnight standbyhttps://www.dropbox.com/sc/t64536q9a0l0axd/RWJ6_Oq4gJ
In addition I've used a2dp audio stream for an hour or so. I'll do a full screenshot of all the on times later.
Still very low usage scenario. Battery looking good. @22hrs 40% with updated screenshots above.
Final Result only took me to 15% with 1 Day 16 Hours. Screen on time 3hr 16mins. Needed a full battery for the day and couldn't risk it but atleast it's a general ballpark. https://www.dropbox.com/sc/oaj33ji9kssx5rt/BFiLIz-Jef
40 Hours is still pretty good for light usage. During a busy working day i would be happy with 9 hours max usage.
