You might follow me on Twitter, but we both know Twitter is very noisy. They are probably doing some dirty stuff in JavaScript which is draining your battery like hell. Kill the most greedy websites with fire and notify their developers. If you feel that your laptop battery is struggling because of the Chrome, check out the Chrome Task Manager. I can live without pinned tab about exchange rates, if that makes my laptop alive for twice the time. And look at this, when I have this page opened and pinned: Tab XE.com is sooooooo CPU intensive (the tab was inactive when I created the screenshot) I had the currency exchange rates (USD to EUR) opened all the time. Find the tabs that are constantly greedy for your CPU and kill them with fire! What you’re interested in is the CPU - this is what is draining your battery. When opened, it will reveal more fine-grained details about CPU and RAM spent within Chrome. It is called Task Manager and you can find it in Menu > More Tools > Task Manager. There is one not-so-well known tool in Chrome, that allows you to analyse how much resources the individual tabs consume.

It is normal that it is losing its power over time. I use Chrome for this, I rarely open any other browser - most of the time for testing only.Ĭhrome 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.įor 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. This is mostly because I read stuff, stick on social media or develop websites. I spend most of the time on my laptop in the browser. It is so easy to do once you know where to look.
