There are reports that the developers found that OS X 10.8.1 will extend battery life. But after the test of the MacBook users, the OS X 10.8.1 disappointed us in improving battery life.
Although the developers confirmed the battery life is greatly enhanced after the mountain lion is updated, the test results are completely different in real life.
The Mac portable models improvements using the Core i5 and Core i7 processor from 2011 to 2012 are the most significant, the website OS X Daily said.
After a series of tests, the conclusion of the site is that computers with Core 2 dual core processor almost have no change in battery life after upgrading the mountain lion.
There are reports that, in different MacBook Air models, the OS X 10.8.1 does not improve battery life.
MacBook Air 13 “Core i7 (in mid-2012)
OS X 10.8.1 – 4:36
OS X 10.8 – 4:33
MacBook Air 13 “Core i5 (in mid-2012)
OS X 10.8.1 – 4:48
OS X 10.8 – 4:31
MacBook Air 11 “Core i5 (in mid-2011)
OS X 10.8.1 – 3:26
OS X 10.8 – 3:32
MacBook Air 11 “Core 2 (end of 2010)
OS X 10.8.1 – 5:45
OS X 10.8 – 5:47
Of course, this test may be unscientific, an additional process running in the background may cause the battery time reduced from 10 minutes to an hour, but it seems that the OS X 10.8.1 doesn’t bring significant improvement in battery management.
The 2012 MacBook Air battery life decline is the fastest, a few months ago it can run more than eight hours, but now the use time is reduced by half.
Any lithium-ion batteries battery life will decline after several months use, but such a sharp fall is not normal.
Apple never said the battery drain patch was added in the OS X 10.8.1, and it’s said that Apple is commit to this work, and they hope to see this function in OS X 10.8.2 (in testing phase) .
