Our tests have shown that it can give you about 20% more runtime, which you can spend writing, browsing the web and watching movies. 

• How Endurance saves battery life: Customizable Endurance can automatically activate the following energy saving modules. Prefer not to use a certain module? You can turn it off so it won't bother you. Turning off Turbo mode. Your processor, the brains of your computer, can go into overdrive, which uses up a lot of processor. By turning off Turbo, your computer will run a little bit slower, but it'll last a lot longer.

   

• Quitting greedy apps: Did you know that Chrome can take up 20% of your battery, even when it's just open in the background? Endurance keeps track of what's gobbling up your energy and puts those apps to sleep. Reopen them, and your tabs are right where they were.

   

• Dimming your screen: Your big shiny screen takes a ton of electricity to run. Endurance can slowly dim it over time, but like a frog in boiling water, you won't even notice.

   

• Hide background apps: Your Mac is smart enough to slow down apps which are hidden offscreen. So we just automatically minimize them when they're in the background.
