macOS 10.15.7 battery life is HORRIBLE

[SW3029]

Ever since upgrading to macOS 10.15.7 on my 16" MBP I'm getting about 4 hours of battery life max. Just in the last 15 minutes, my battery life has decreased by 11%.

Anyone else experiencing this?

How are things looking in Activity Monitor under the "Energy" section?

As with the iOS updates, your Mac is likely re-indexing your hard drive post-update which will always cause a short term decrease in performance and battery life. This will likely level out after a day or two

I am having basically the same issue on my iMac Pro (128 GB of RAM). That "Energy Impact" figure accountsd has been up around 700 for the last two days and is basically stopping me working. The Parallels VM I need for work is only at 75 and that VM is 300 GB!! So what is MacOS really doing?

PS: CPU load is well over 85% and I'm not running Parallels or any other applications at all (except this browser).

The other day Audacity (just sitting in the background doing nothing) sucked my MacBook Pro 13" from full to empty in 1,5 hours. I didn't bring my power-brick to Starbucks, therefore not happy.

Battery life has been horrid since the upgrade from Mojave...4 hours seems normal in my experiences too. macos 10.15.7 mba 2012. Battery with 32 cycles.

I'll agree with you on this. Out of curiosity I checked my "energy usage" in Activity Monitor and even though I had no app with a usage exceeding 0.2 my MBA's battery dropped 3% in 7 minutes.

Signing out of Apple-id and signing back in ended the accountsd ramp up the fans and extreme high cpu usage in activity monitor for me on mbp 2018
( suggested by some on a tread about acountsd high cpu usage after latest update somewhere on macrumours, thanks!)

I have around 1k cycles on my A1466 2013 battery. 10.15.6 lasted maybe an hour. After upgrading to 10.15.7 it's 5 min if I'm lucky. It takes the entire night to show full charge.

Maybe the battery is finally shot and it's just a coincidence. But I wouldn't put it past apple to sneak in some kind of firmware patch to cripple older devices.
