Updated MacBook Pro to macOS Sonoma, now battery drains quickly

I updated my MacBook Pro this morning to macOS Sonoma. Everything was good at first and I really like the look and feel. But as soon as I took it off my charger to go to some meetings the battery dropped from 74% to 44% in about 5 minutes. Then as soon as I turned on WebEx the battery dropped from 44% to 7%.

Anyone else having battery drain issues with macOS Sonoma? Is it maybe just temporary from all the background activity similar to the phones?

One significant contributor to MacBook battery drain after updating to Sonoma or any other new OS is the background setup processes. These background activities like Spotlight reindexing, Photos synchronization, Time Machine backup operations, emails, messages and other app updates.When your MacBook is working on these tasks, it puts an additional burden on both the CPU and GPU, leading to increased power usage and battery drainage. Generally this battery drain is temporary. The best thing to do is to monitor your battery situation and, if active, connect your Mac to a power adapter, allowing them to complete without interruption. This shouldn’t last longer than a couple of days at most.

I tried reinstalling Sonoma again to see if that fixes things, and it does not. It just *flies* through the battery when the lid is closed.

If the battery is being zapped to zero every single day (as is the case for myself and others, hence this thread) it is definitely taking a toll on the long-term life of the battery.

It's definitely happening on older hardware (2019 Intel MacBook Pro here).

While it may not be just a Sonoma matter, it's clear from this thread that for many of us it wasn't happening until we upgraded to Sonoma.

In that discussion, the topic of conversation is battery life, not battery drain.

I submitted my feedback on September 21st, but I have not received any response yet.
