Newest macOS preview build removes battery time remaining estimates
Apple's latest MacOS Preview build (12.12.2 beta 4) does away with the battery life estimation feature, leaving only an option to show the battery percentage. The update comes after many new MacBook Pro users complained about poor battery life on both the MacBook Pro 13" and 15"—a move that may just be coincidence, but is likely a direct result of the complaints, according to sources.
According to Apple, there is no hardware problem—or any problem at all—with battery life on their new MacBooks. Instead, it seems that they are blaming the complaints on inaccurate battery life estimates, which are a result of the software having difficulty properly projecting power consumption for the more modern CPUs in the new notebooks. Apple seems to think that it's better to simply remove the feature than to improve its method of estimation, according to 9to5Mac.
However, there is another way to check your "time remaining", if you're dying for a number: the feature is still available though nestled away in the Activity Monitor in the Utilities folder. It's not as convenient as clicking on a menu icon—but if the estimates are wrong either way, maybe it's for the best.
