Did you do a factory data reset after ICS installed? Some apps were not designed for ICS and some that were didn't make the transistion well on the same install going from GB to ICS.
As for battery life, not doing an FDR and having some apps misbehave can cause serious battery drain. But there is also another possibility. I recently got a new batter (3 new batteries in fact) off Amazon because the original one that came with the phone was starting to drain faster. The issue was it was merely the end of the life of the battery.
Keep in mind, you have had your phone nearly 2 years. Thats 600 or more charges on the battery if it's original.
