Is this accurate? RIDICULOUS Energy Impact and 12 Hr Power Values

I'm noticing CRAZY values for "Energy Impact" and "12-hour Power" in Activity Monitor. I started to notice these after upgrading to Ventura. Is this REALLY true, or is this just not accurate? I am downloading around 54 instruments at the same time from Spitfire so obviously it should be using a decent amount of power, but nearly 4,000? And Chrome—what the heck? I am running 2 profiles in Chrome each with ~10 tabs. Screenshot below:

Also, when using VCV Rack, I see Energy Impact values upwards of 20,000. This has to be misreporting...

Is this on M1?
I'm having exact same issue after updating to Ventura on my M1 pro 16 inch! My coworkers who upgraded to Ventura but with Intel chips, have normal numbers there.
I have crazy numbers in energy consumption, but at the same time, laptop is running cool and smooth. Although I noticed decline in battery life, not dramatic but still.
Quick posts on apple discussion forums and on Reddit didn't help, and I yet to find anything on google, and I'm too lazy to downgrade to Monterey :(
 
@alkali147 Yep, on an M1 MBA. I'm experiencing a noticeable drop in battery life after upgrading, too—about 1-2 hours shorter than what it was... and the battery health is still at 89%, so pretty good. Interesting, I'm glad it's not just me that's experiencing this.
 
upgraded to Ventura 2 days ago, MBA M1, 96% battery health.. this is ridiculous yes
switched browser every 2 hrs, casual web browsing (twitter, reddit, YouTube, stack overflow)
extensions installed
on safari: adguard adblocker
on chrome: ublock, tampermonkey, surfshark

did anyone downgrade to monterey?

I did little investigation: so all of my colleagues with M1 chips and Ventura experience same issue, while it seems not to affect Intel chips.
It's not only browser, but generally all apps show crazy high energy consumption in Activity Monitor. I've sent this information to Apple through Feedback but no response of course.

Did clean reinstall of Ventura - didn't help.
Booted in safe mode - same behaviour.

Weird thing is that all worked just normal - laptop was cool to touch, fans didn't spin and system was snappy.

Part of me thought that it's just Activity Monitor bug, and it just doesn't report correct numbers, but I saw noticeable decline in battery life - with my normal usage I averaged around 5% battery life per hour, and after upgrade it was 8% in best case, so around 50-70% less battery life.

Finally I had to just erase disk and reinstall Monterey, and all is back to normal. I'll probably wait for 13.1 and then see if there are complaints from others. bummer.

It's strange that it's not reported more - I stumbled upon only this post in here.

EDIT: for reference, this is image from Activity Monitor in Monterey, literally, 10x less energy impact reported.

What units are the numbers in for Energy Impact and 12 hr Power? Power would imply Watts but I have no idea what the units are for energy impact. Without knowing what the numbers mean, how do you know that they are ridiculous?
 
I'm seeing this impact on battery life, too, but only since the official build, 22A380. Was not an issue prior. I'm getting at least 3-4 hours less in battery life.

This really sucks—maybe they will fix it in 13.1 or maybe there will be a 13.1.1 update to fix this issue.

Yesterday I felt my MBP was actually slightly warm - which is unusual.

Activity monitor revealed that the Weather and Home apps were using a silly level of processor. All I had done was go to each sometime in the morning and minimise them out of the way. Quitting them both resolved the impact and temperature dropped to normal. (On my mini, Weather was doing the same. But Home was hardly doing anything. However, I had not done anything within Home - just launched it.)

I feel that they should have next to no impact if not actually displaying anything.

It is like index number without unit. I read before it takes actual energy impact and wake-up times per unit time of an app, then it will score the app based on a formula. It could be different in the latest OS tho.

Help under Ventura (on a mac mini, in case that is relevant) says:

The energy use of individual apps and their processes is displayed in the upper part of the Activity Monitor window.

  • Energy Impact: A relative measure of the current energy consumption of the app (lower is better).
 
my M1 Max 16 inch is not getting more than 8 hours of battery life. It used to last 10hrs+ easily.
battery health is 100%

On my 14 inch, I find some things use far more resources than I'd expect.

For example, Activity Monitor and Weather.
 
My 14" MBP is experiencing issues, too.

Activity Monitor is using around 26.00 on the Energy Consumption monitor in recent times, draining the battery rapidly. I'm not sure what to do - but it is absolutely related to the installation of Ventura.

Ventura 13.1 seems OK.

The obvious answer is to close Activity Monitor, if it is still happening.

Might be best way, but for me it was quite obvious without doing that. The machine felt warm (not hot). Close Activity Monitor and temperature drops. Entirely repeatable. It never otherwise feels that warm.

Maps also bad and also, I think, much better on 13.1.

I do see the battery draining faster with 13.1. Still better than PCs but I would like to see it back to normal asap.
