I'm also L720 user , and today I has already updated the touch update , however I did not feel any battery improvement perhaps my phone's firmware is still under GDR2 , or I did not amend any setting .
This update was for "touch" app of Nokia. So only vibration affected the battery life.Did you "disable vibration" ? That's what is causing the difference. Not the update in itself.
