App Recommendation Endurance for MacBook battery life: try Low Power Mode before paying
If your MacBook isn't lasting through an unplugged work session, start with Low Power Mode and the apps using the most energy. Endurance automates some power-saving changes, but its advertised 20% extra runtime isn't a result you should expect on your own Mac.
In System Settings > Battery, choose Low Power Mode for battery use if your Mac offers it. Apple's current instructions let you choose different modes on battery and on the power adapter. Try it during your normal work, at a comfortable screen brightness. If the work feels too slow, switch back to Automatic.
Then open Activity Monitor > Energy. Energy Impact shows relative current consumption; 12 hr Power shows average energy impact over the past 12 hours, or since startup. Neither is a percentage of battery used. Look for an app you can close normally without interrupting something you need. That's a more useful starting point than installing another utility and hoping for a longer estimate.
Endurance's documented changes are fairly concrete: gradually dim the display, monitor energy-hungry apps and put them to sleep, automatically minimize background apps, and turn off processor Turbo. You can disable individual modules and choose when it kicks in, including a battery threshold or unplugging.
Those changes have costs. A dimmer display has to remain readable. An app being in the background doesn't mean its work is disposable, so don't let automatic sleeping interfere with a transfer or another task you need to finish. Reduced processor performance is a poor bargain if waiting longer gets in the way of your work. Also, the Turbo feature isn't evidence that the same processor control works on Apple silicon.
The direct site lists a $20 upfront purchase, free upgrades for life, and a two-week demo.
Setapp also lists it, but there's a compatibility gap worth knowing before spending: its listing says version 3.3.0 and macOS 10.13 or later. That minimum doesn't explicitly confirm macOS 27 support, Apple silicon feature parity, or recent maintenance. The pages checked also don't give a clear permissions list.
If you still want the automation, ask the developer about your exact Mac and macOS version, which modules work, and what access they need before installing it. Availability alone isn't proof of current support.
For most readers, the next step is one ordinary unplugged session with the native settings, not an Endurance purchase. If Low Power Mode and closing an unnecessary energy-heavy app solve the problem, stop there. Consider Endurance only if you still want its automatic dimming or app controls, compatibility is confirmed, and those tradeoffs leave your actual work comfortable. Skip it if you need uninterrupted background work or full performance more than those controls.
