Consumer Reports is standing by its initial findings that caused the agency to not recommend the MacBook Pro due to battery concerns. The agency said that it is confident in its results and won't be rerunning its tests. In this case, we don’t believe re-running the tests are warranted for several reasons. First, as we point out in our original article, experiencing very high battery life on MacBooks is not unusual for us – in fact we had a model in our comparative tests that got 19 hours. Second, we confirmed our brightness with three different meters, so we feel confident in our findings using this equipment. Finally, we monitor our tests very closely. There is an entry logged every minute, so we know from these entries that the app worked correctly.
