How I doubled the battery life on my Mac by literally closing one tab in a browser Primož Cigler Follow Feb 17, 2016 · 4 min read

Today I want to share a quick and easy hack that doubled the time-on-battery on my laptop.

It is so easy to do once you know where to look.

I spend most of the time on my laptop in the browser. This is mostly because I read stuff, stick on social media or develop websites. I use Chrome for this, I rarely open any other browser — most of the time for testing only.

Chrome is generally known not being energy efficient app, so it is a trade-off, but I find it much better (especially for dev) than anything else.

For quite some time now I started to notice that the battery is not lasting as long as it used to when I bought this laptop a year and a half ago. It is normal that it is losing its power over time. But then one day about 2 weeks ago, when I was lying ill in my bed, I decided to check what is draining my battery so fast and if I can fix it.

Fortunately the OS X comes with the Activity Monitor, which also gives you the overview which apps put most impact on your battery life.
