There have already been a few reports about the new Apple MacBook Pro battery life not being constant. Users have reported that the MacBook Pro would have great battery life once day nad terrible battery life the next day and Consumer Report seems to agree as well.
Consumer Report tested out the new MacBook Pros and reported that the 13inch MacBook Pro with the Touch Bar features will last about 16 hours in some of their test and only 3.75 hours in the another. The huge gap also happened when they tested out the model without the touch bar although the one without did last a little longer than the model with the Touch Bar.
Some people have since suspected CR’s testing method is has urged them to retest the MacBook Pro but CR made it clear that re-running the test will not bring any difference as they are confident that their testing method is correct.
