Battery life is now much improved and everything seems much faster response wise.
I am now using mobile ODIN pro by ChainFire to install my updates.
Advantages to this are you just place the update file on your external memory card and mobile ODIN pro automatically installs everything in the correct order.
If you choose the everoot method it will keep your device rooted.
It also installs a copy of itself as a system app so it's ready for your next upgrade.
Below you will see Mobile ODIN ready to flash update.
