Battery Life Issue After macOS Sequoia Update

Facing the same issue. After sequoia update my Mac lost 2% in its battery life and it's not even 5 months old yet. Apple didnt help me a lot with this. It's a very concerning issue because Mac batteries are supposed to last a long time. I am down only 30 cycles and life is already at 98%.

A battery is just a dumb brick. It discharges based on the energy that is drawn from it. Whether a battery charge goes up or down, in any timeframe, is totally irrelevant to anything.

What is the source of the energy drain?

It seems I have fixed my issue with fast battery drain. I have fully drained battery by using Mac till it's going to deep sleep by a low battery condition. I closed the lid plugged a power adapter and waited for a few hours to allow Mac charge the battery.

I am experiencing the same Problem. After the Update to Sequoia 15.0.1 my Macbook Pro with M1 Pro CPU Battery discharges faster then before. And it gets a lot warmer on the underside then before. I have checked the Activity Monitor but since i have no before/after there is nothing suspicious.

This is obviously a real issue with Sequoia. My battery life is so bad now that I have to keep my charging cord within grabbing distance as I move around the office. OK, Apple, we need a fix for this!

I had the same issue, when streaming a church service, the battery would drain even though the Mac is attached to the power adapter, and never had this problem before the upgrade to Sequoia. That was version 15.0 of Sequoia. I updated to the latest/greatest 15.1 and the problem has resolved. The battery stays fully charged while streaming.

Try that first before worrying about battery health, third party power hogs, etc. If things were fine before going to Sequoia they should remain fine, now that we're beyond a dot-zero version.

Same here. MacBook Air M2. After installing Sequoia, battery drain, no obvious culprit app. I just tested behaviour with Wifi and Bluetooth off, low power mode:

battery level went down linearly from 75% to 63% in 9 hours in sleep mode. That's 1.3% per hour for naught.

Open Activity Monitor in Utilities>View>All Processes>Energy tab, sort on Preventing Sleep, any listed?

Everything is set to "No", but I feel it is not something related to this aspect.....even while I work, the Mac seems to require more energy.....

interesting, I'll give it a chance

Macbook Air M2 2022 at first my battery last whole day without charge but after the update its like 8 hours a day i guess... also i felt even in the lid close the battery is draining

my M3 pro last 4/5 hours.......before the upgrade battery lasts all the day...I'm trying a lot of fixes, but nothing works....I hope that Apple will release a patch.....

Yes, taking up so much battery even with just normal use.

Mine as well draining fast.

Same problem here on my M3 pro Macbook Pro. Before uptdate 5-6 hours without charging, after update 4 hours max
