"Why's my battery draining so fast?"

You've only been working for an hour and your battery's already half-drained—not good. Usually this happens when an app becomes unresponsive or simply requires a lot of processing (CPU) power. The more CPU it uses, the faster the battery drains. It can be especially frustrating when you don't realize it's happening until it's too late.

Take control of your battery life.

That's why we created Coolant, a menu bar app that lets you know when an app is using an excessive amount of CPU or memory so you can close it and save battery power. With Coolant you're never blindsided with a quick-draining battery, you can continue to be productive for hours more.
