unless you don't need, don't enable smart reflex, it can cause unexpected reboots. Just search tmo about smart reflex and you will find countless threads on that. only if you have 3g on it takes battery like anything. if it is on 2g then battery can go for longer duration. Also, if your battery is more than a year old and in higher temperature then it will go down faster.

Except for the patch which had some values enabled, the patch doesn't seem to impact the battery life.

Use swappolube and increase vfs cache pressure to 1000 or 2000 and your battery should improve.
