I wouldn't go as far as @mai_tsla in commenting on the possible effect of Chrome on the battery. However, he has a point. I use Chrome on my laptop and there are these nasty support routines in the background called "Google Chrome Helper" that eat up CPU resource, so it could have a bad effect on other display functions.
Over the 5 years I've owned my S, the display functions have become slower and slower, and not just the browser. The car used to power up in less than a second. It now takes about 5 or 6 at least after hitting the brake pedal. In the latest version (I'm on V9.0 - 2018.50.6) the media app can take over a minute to boot up. While these longer times are hardly life-threatening, it does represent a noticeable deterioration in the user-friendliness of the car. I used to get in the car, hit the bake pedal, immediately flip the drive lever and off we go. Now it takes as long as turning an ignition key, pressing a starter button and selecting a gear ... ouch.
