I'm currently running SL on my MacBook5,2 and am considering whether to upgrade to Mountain Lion. I've heard that:

1. the initial version of Mountain Lion caused short battery life on laptops.

2. that this had been addressed with subsequent updates.

Q: In fact, has this issue been resolved?

Moot subject, deed is done.
