Endurance

FYI: 7-day free trial. $12.99 after that

Hey Eric! Thanks for hunting Endurance! It's a brand new product for your Mac that does exactly what it promises — makes your battery run longer over the course of the day. In our tests we're able to get between 15% to 25% more uptime, a really nice improvement. Why'd we build it? Our Macbooks performance is great, even the ones that are a few years old. But the batteries all start to fade after so many charge cycles. It's particularly frustrating when you're working from coffee shops with no outlets or on long flights. Endurance runs in the background on your Mac, sitting nicely in the menu bar. When your battery hits 50%, it asks you if you want to enter Low Power Mode. Endurance makes your battery last longer by combining a lot of different modules together. We can slow down your CPU, notify you when there are processes like Flash and Chrome which are gobbling up cycles, hide background applications (causing AppNap to de-prioritize those processes), and automatically dim the screen over time. If you don't like any particular module, you can turn that one off. Happy to answer any questions!

Endurance is an app that helps your Mac run longer. It runs in the background and when your battery level drops to a certain level, it automatically starts adjusting your settings and turning off features which use a lot of energy.
