While OS X Mountain Lion might be Apple's latest operating system at the moment, it might not really be the greatest as far as MacBook Pro users are concerned. According to a test conducted by Ars Technica, they have discovered that there might be evidence to suggest that it could be draining battery life on MacBooks faster than its predecessor, OS X Lion. Their test results have shown that they have lost about 38% of runtime after upgrading to OS X Mountain Lion. This is compared to the 8 hours they managed to achieve with Lion versus the 5 hours they got with Mountain Lion.
