flash vs html5 which uses less battery power?

On my little 2in1 Acer Tablet running Win8.1 with Bing, which is free to the manufacturer by the way.

I get an estimated 7hrs with wifi and bluetooth on for my mouse, and using low brightness, now most people know that watching video uses more battery life than just browsing web pages so i was wondering.

Which uses less battery flash or html5 video , the test below says html5 by up to 17% not a lot and html5 is not a option for video playback on a lot of sites.

Any opinions are welcome

I agree that HTML5 is the winner here regardless of the browser used. That said Flash might be worse or a lot worse - I also have a 2 in 1 - Acer Switch 10 in my case, and for whatever reason Flash video uses far less CPU power in IE11 than the same video on the same website in FF. I did a lot of testing and regardless of settings and HW acceleration IE 11 always wins by a large margin over FF. There seems to be no difference as far as HTML5 video is concerned between these two browsers though

So basically - HYML5 is better, but if you are forced to use Flash video - you'll use less juice watching it in IE11.

 

Yeah that`s what i have an "Acer Switch 10"

The Acer Switch 10 has the power options locked up so you cannot adjust a lot, below is a easy registry hack to give you full access.

Spoiler: hack

Best solution yet, IMHO, for anyone who wants to maximize battery usage and doesn't care for connected standby:
1 - Enable hibernation button and a bunch of hidden power settings through this simple registry tweak:
HKLM\System\CurrentControlSet\Control\Power\CsEnab led (1->0)
2 - It gives access to "power saving" mode, its settings can now be tweaked to enable even more power saving modes for wifi, usb, cpu, etc;
3 - Optionally, it is also possible to completely disable connected standby by disabling 3 wake-up settings in the wifi adapter properties. Seems that it makes windows believe that the hardware is not compatible with connected standby anymore.
4 - Uninstall Chrome because it really uses lots of CPU power and prevents idling, as confirmed by "powercfg /batteryreport".
5 - As an overall result, battery is certainly lasting more than 11 hours from 100% to 5%. Haven't done the math yet, but it is using much less than 10% per hour under half brightness. And not a single 1% is lost during hibernation. Also, hibernation is very quick to wake up windows, takes only about 5 to 10 seconds.

EDIT : the "Ultimate Windows Tweaker 3.1.2.0" is a good app as well.

Flash is bloatware. Not efficient. HTML5 is the future standard, and heading that way.

 

Yes is is but it's heading there very slowly. I have heard that flash is dead years ago and let's be honest - it isn't. You still have to have it since multiple websites insist on using it.

 

I just uninstalled flash. All those ads now using it are killing web site performance, including this site.

 

I believe HTML use less resource/cpu. On my win tablet, all browsers are a joke compare to IE11(desktop mode).

Now that you mention it, I just realize my win tablet don't even have flash installed.
