A fair number of Mac users have found that macOS Tahoe has notably reduced the battery life and battery performance of their MacBook hardware. Looking around online, you’ll find a variety of complaints from MacBook Pro and MacBook Air users about quickly draining battery and significant reductions in battery life in general, since installing the macOS Tahoe update.
While it’s fairly common for MacOS to be slow with less-than-great performance after installing a new system software update as MacOS runs indexing and background tasks, that process is usually self-limiting and resolves itself in a day or few. The battery issues that some macOS Tahoe users are complaining about do not resolve after that initial indexing process has finished, however.
Potential battery and performance issues like this are why some users delay updating to macOS Tahoe as they’ll likely be worked out in future bug fix updates, whether that arrives as MacOS 26.1, MacOS 26.2, macOS 26.3, or later, is yet to be determined.
Here we will review some tips to help battery life and to identify what is draining battery quickly with macOS Tahoe, to improve things where they can be.
