So i refreshed the device & re-installed some of the apps etc - used the device, ran updates etc and from the battery report it is showing me that the device has been active/used for 7hrs. Switched the device on this morning and I still have 61% remaining !!
23:14 Device was suspended at 63%
08:22 Device was active when i powered up with 61% juice
so, looks like the I may have a result!
Although i am yet to install Google Drive & Adobe PS/Il
