Firefox uses alot of battery (especially compared to Edge-ium)
Hello. I'm an avid fan of Firefox; never liked Chrome, never cared for I.E. and original Edge was there. Since Edge-ium came out, when I'm on battery, I have been testing it and there's a marked difference in battery life when compared to FF. I don't run many add-ons and from what I can tell, both browsers are set the same (options).
On Edge-ium I can achieve up to 5 hours of battery (Lenovo Yoga 730 4K). On FF, I'm lucky to hit 2hrs. Help?

I've noted this in our logs for FF. Have you noticed this over several versions? Could be a bug.
Hi Eve,
I'll include some history. In April 2019 I purchased this new Yoga 730. My Previous laptop was a 6yr old Lenovo IdeaPad, maxed out memory and Samsung SSD.. still works quite well and fast. HOWEVER, the battery would drain drain drain. OF course being 6yrs old, I assumed the battery. I'm going to have my wife try Edge on that machine to be 100% certain.
Moved to my awesome Yoga. I thought I had a dud! I even used my extended Warranty and got a new battery. Lenovo said that my model was known to have been MAYBE shipped with bad batteries and/or corrupted Motherboards. Ok.. Replaced.. SAME ISSUE!!
I called Lenovo again. This time they said "Look.. you have a 4K screen.. that thing is bound to use power" I called the tech back.. he somewhat agreed...
I resigned to accept that this was my life.
ALONG CAME EDGE-IUM... Since as long as it's been out, I've noticed that when I check the battery meter in Windows 10 systray, FF shows me at best 2hrs 2 min. while Edge-ium shows me 5hrs? 4hrs 30 min??
I'm basing my judgement off the info provided by the attached icon when on battery.
Firefox uses a lot of battery. Maybe the cause is today's modern web pages. So try with "Ublock origin" addon Because That is an efficient blocker. Easy on CPU and memory.
I've had this issue for years with Firefox.
Edge and Chrome don't have the same power drain.. so it's something with the Firefox "engine"
Hello BRAM SCOLNICK,
I found this article, that might interest you :
McCoy - thanks for the link; however, that article is from May 25, 2018. Edge was already known to be using less power, b/c it did much less. The current version of Edge, based upon Chromium (aka Edge-ium) still uses less power than FF or Chrome; and there's no reason for FF to be using so much battery juice.
Is anyone from Mozilla reading these?

Maybe Eve can answer that question ..... (?)
You can try to disable hardware acceleration in Firefox.
- Options/Preferences -> General: Performance
remove checkmark: [ ] "Use recommended performance settings"
remove checkmark: [ ] "Use hardware acceleration when available" - https://support.mozilla.org/en-US/kb/performance-settings
Close and restart Firefox after modifying the setting for changes to take effect.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
