Except Chrome, which on every laptop I've ever used seems to decrease battery life by about a 1/3rd compared to Safari and is always marked as using significant power. (Currently 10.9.5 with chrome 44 on a 2014 macbook air, but I've had the issue on newer computers at work)

If your a developer at Google that is looking for a 20% time project here is your opportunity! Make some fixes, write it up and post about it somewhere and we will up vote your story and give you sweet HN karma. :)

At least for me, that's partly because Chrome makes it _so_ easy to "overuse" it. I'm right now writing this comment in a window with 29 tabs open, I have three other chrome windows with 22, 17, and 14 tabs open respectively. It's sitting there at 42.3 in the Energy Impact column and 32.23 in the Avg column - but to be fair it's got a whole bunch of stuff going on (two separate gmail instances and a fair few other javascript-heavy webapps as well). I've probably go more bogomips going on in this one browser window that all the machines I learnt to program on were capable of between them...

  I'm at 47.91 average impact for FF 40.0 with uBlock Origin and Ghostery, no Flash installed. Doing local web development and poking around some news sites to read about all these market crashes. Only a few tabs open at a time for me.

  Hmm… comparing that to the amount of tabs and windows I have open in Safari right now (which is actually pretty low for me since I usually have more than 250 tabs open) seems to make Chrome look even worse… Specifically (running Safari v7.1 on OS X v10.9.5), I have 18 windows open containing 2, 18, 26, 16, 2, 12, 17, 13, 21, 6, 2, 2, 1, 1, 2, 1, 1, and 4 tabs for a grand total of 147 tabs. Oh, and I forgot to mention, it’s also downloading two files in the background right now. It’s showing up with 13.2 in the Energy Impact column and 4.47 in the Avg column. (Oh, and since I already have it open, I may as well mention that Firefox 39.0 shows up as around 14.7 in the Energy Impact column (although it keeps spiking to 23.9 every few seconds) and 2.99 in the Avg column with 2 tabs open in 1 window with no downloads).

This can be seen exceptionally when watching videos where some implementations prefer Flash. I often fall asleep to documentaries (maybe not a typical use case) and I've seen massive gains in battery life using Safari (using HTML5 video) vs. Chrome (using Flash). Granted, this isn't a fair comparison as one is using a "native" implementation and one is using Flash. But I've seen something like 250% gain in battery life – which sometimes means the difference between seeing the ending and not. It's interesting watching one's projected battery life climb from 40m to 1h 40m simply by swapping one application for another. However, it's unfortunate some websites prefer Flash-based implementations over their native counterparts. Although this trend seems to be shifting in favor of those that are native. And I assume the smart folks at Google are taking note. YouTube, for example, has done a particularly spectacular job at adding AirPlay functionality to their HTML5 player. (Disclaimer: I work for Apple)

  There is currently no good browser for apple. Safari (8.0.8) struggles with HTML5. Firefox (40.0.2) struggles with video/media of any sort and bogs down with multiple tabs. Chrome (44.0.2403.157 (64-bit)) drains your battery. I'm on a MacBook Pro (10.10.5, 13-inch, Early 2015). They are all uniformly disappointing.

  <offtopic> Do you notice that this is the typical developer answer to bad software? I don't believe that anymore until I have the next version in my hand for a test (in case you might answer again, next version...). </offtopic>
