What about users that reported bad battery life?

Migrating to a new Mac puts some stress on battery while everything is indexed for Spotlight or backed up to a Time Capsule. That's why Macs will tend to have bad battery life in their first few days.
> After working with Apple over the holidays, Consumer Reports now says that the problem was caused by an "obscure" Safari bug specific to page caching, which the publication disables when it runs its battery tests. To test battery life, Consumer Reports sets laptop screens to a specific brightness level and then loads a series of webpages in the laptop's default browser (Safari in this case) in a loop until the battery dies. Apple suggests that disabling browser caching for a test like this doesn't reflect real-world use, but it does make sense for a synthetic test—users will continually read new pages rather than visiting the same static pages over and over again, so Consumer Reports wants to make sure that its test is actually downloading data over the network rather than simply reading cached data from the disk.
