According to user reports following the release of the update, there are quite a few who are claiming to see an improvement in battery life. MacRumors forum member lobo1978 was quoted as saying, “Ok it is official. macOS Sierra 10.12.2 fixed my battery. I am up back to 9-10 hours of regular use. Before updating, idle power consumption was not going lower than 6 watts. On macOS Sierra 10.12.2, it is now <4 watts at 60% brightness with the ambient light sensor on.”
Another member by the name of JohnnyGo says, “Before the update was getting 7-9 hours with 50-60% brightness. Now getting >10 hours with 70-75% brightness with the same workload (Wi-Fi and Bluetooth on of course).” We’re not sure if the update has anything to do with this improvement, or if maybe it could be psychological.
In macOS 10.12.2, Apple removed the “Time Remaining” feature in the battery status bar as the numbers varied too wildly. It could be that the removal of the feature has stopped users from constantly checking, but what do you guys think? Any MacBook Pro owners out there who are also seeing improved battery life?
