It is appreciated that Apple actively work on improving operating systems, especially in those aspects that we do not see with the naked eye and that could have been left as they are. But if you want to boast of one of the most refined and efficient operating systems, you must correct and improve, not only graphics card errors, but also certain parameters that are "under the hood" of our Mac.
On this occasion, several users of the new MacBook Pro report in various forums, than battery life on macOS Sierra 10.12.2. is better than its predecessor.
But we are not only talking about user impressions. Some users would have checked, with battery management apps like CoconutBattery, who the battery consumes less power, which translates into more hours of use. This is how the users tell us:
Ok, it's official. MacOS Sierra 10.12.2 improves my battery. Allows me to use it between 9-10 hours of regular use. Before upgrading, the idle power consumption was not less than 6 watts. In macOS Sierra 10.12.2, it is now less than 4 watts, with a brightness of 60% with the ambient light sensor on.
Before the update I had used between 7-9 hours at 50-60% brightness, now I get more than 10 hours at 70-75% brightness with the same workload (Wi-Fi and Bluetooth of course) .
This is a sample of users and therefore, we cannot conclude that Apple has worked on optimizing its operating system, by virtue of an improvement in battery life. But it is true that the values obtained by users are close to those promised by Apple in the specifications of the new equipment.
Following the release of macOS Sierra 10.12.2, Apple indicated to The Loop , which after many tests, is now close to the commitment made, committing to the duration of more than 10 hours with one use, with consumption of resources such as Wi-Fi or video playback.
