Updated MacBook Pro to macOS Sonoma, now battery drains quickly

Have the same problem. Shutting of wifi before going to standby solves it for me.

Not sure what is happening when wifi is on during standby, but it sure is taking all the energy from my battery in Sonoma.

Some apps are working in the background eating up the energy. Best get rid of background apps, 3rd party modifier apps, 3rd party antivirus apps, OneDrive app or at least it's syncing with the "mother" server.

If nothing helps, isn't it better to go back to Ventura and wait until your MacBook becomes compatible with the new Sonoma?

My Intel i7 2018 Touch Bar, by the way, is compatible with Sonoma and ran 7 hours on battery and still had 25% of battery power with normal daily work with wifi, bluetooth on.

Macbook Pro 14" (2023) M2 Max's Battery Maximum Capacity is decreasing faster after Sonoma update. Like iphone 13 Pro Max's Battery Health after the iOS 17 update.

Macbook Pro Maximum Capacity decreased from 99% to 98% in a week. I have no new software on my Mac except Sonoma :)

Looks battery goin' to die so fast.

The Battery's Maximum Capacity percentage change has nothing to do with Sonoma except for the calculation of the percentage value since the percentage is being calculated from raw information/values provided by the battery itself. The Apple batteries have their Full Charge Capacity (FCC) fluctuating up & down in minor increments even with a good healthy battery. These minor fluctuations of the battery's FCC can result in a several percentage change shown & reported by macOS as the Battery Capacity percentage. Keep in mind, this Battery Capacity percentage was only introduced to the average user with the release of macOS 13.x Ventura, so most people have no idea how this percentage value really behaves on a Mac. I am probably one of the few people who have really performed detailed observations of the Apple batteries because I am responsible for supporting thousands of my organization's Apple laptops.

As for the battery charge levels dropping, see my previous post regarding the most likely culprits. On a co-worker's personal Apple Silicon Mac where the battery charge dropped to 0%, I discovered that iCloud was syncing pictures overnight (this was an Apple Silicon Mac running Ventura...not Sonoma). It wasn't easy to discover.

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.

Not disputing that. Only saying it can be difficult to determine exactly what is causing the excessive CPU utilization & battery drain. I have listed the most likely sources though to look at.

This is a different kind of problem. When working on my MBP during the day there is no battery drain at all. But when put to sleep the battery drains from 70% to 0% in a few hours with wifi on. This doesn't happen with wifi off.

You better read to the end, all those 12 pages. the battery life has a connection to its draining. You'd also find very rarely someone with an Intel chip complains about this sort of thing. What;'s your battery state after ~ 3 years?

In that earlier thread, the concern was focused on battery health rather than battery drain. It's crucial to differentiate between these two aspects since battery drain pertains to a software issue, whereas battery health is related to hardware concerns.

Additionally, with the introduction of the new M1 processors, we used to consistently experience 12 to 13 hours of battery life, which is a significant contrast to the 5 to 6 hours we currently observe in Mac os sonoma. This discrepancy represents a substantial difference in battery performance.

Battery health does not exhibit a consistent pattern with respect to battery cycles for everyone; it varies from one individual to another. Occasionally, it may decrease by 1 or 2 percent and remain stable for extended periods. Currently, my battery health stands at 94% after 200 cycles. We have conducted research in an attempt to establish a correlation between battery health and the number of battery cycles, but our findings indicate that there is no direct link between these factors. Each person's results vary significantly.

Well, I am having an older than yours Intel i7 2018 MBP, after 7 hours on battery it still has 25% power. Work as usual. If the battery state is good, it won't drain that fast. Or, the internal power management is gone haywire. Also, as a consumable product, a battery can go bad all of a sudden. You can also go back to Ventura and check how it goes, for comparison.

Ventura workin time 12-13 hours for my MacBook Pro M2 Max 2023. (Battery Health 98 %) After Sonoma ... decreased to 4 hours.

I have MBP 2016 and Battery Health is 80 %. But using Ventura and workin time 9 hours in avg.

Sorry but Sonoma f* my MBP 2023 Battery Maximum Capacity and Battery Drain in 3 or 4 hours in sleep mode.

investigating how to stop "Idle Wakeups" signals on MacOS. And looks it's hard to prevent in Sonoma. Fixed that problem on Ventura in MBP 2016 last year. It stil ok for me About Battery aging and Drain.

As I previously mentioned in my reply, I've already downgraded to mac os ventura. The reason we initiated this thread was to address this issue, which seems to be a software-related problem. Reverting to a previous OS version is a complex process that involves creating a bootable drive for macOS Ventura, backing up the system, formatting the Mac, reinstalling the old macOS from the bootable drive, and then restoring files from the backup.

During this process, there are still a few challenges to contend with. For instance, Rosetta may not work properly and requires manual update. Additionally, there may be compatibility issues with cloud drive services on macOS since they are optimized for the latest version, macOS Sonoma.

I encountered the same issue, and subsequently, I downgraded to macOS Ventura. If you require assistance with the downgrade process, I can certainly help you with that. However, it's essential that this issue be addressed by Apple's software department. To achieve that, we need to raise awareness about the problem first. I attempted to contact Mac Rumors in an effort to have them publish an article on this issue, but unfortunately, I haven't received a response yet.

Sure, but did anyone gave a solution to get rid of the battery drain with Sonoma, other than reverting back to the older OS? It could just be the state of the battery in a given MacBook. Batteries can die without telling.

Apple has not yet addressed this issue, and it is crucial for them to resolve it in their upcoming updates for macOS Sonoma. Unfortunately, it seems unlikely that they will prioritize this matter unless we draw attention to it.

For Apple to address "the matter", whoever has a problem must send a feedback.

Drawing "attention" here doesn't bring any results. This place is for users to help other users. MacOS and Apple products are proprietary, so the internals are not known/shown to outsiders. So, if you want Apple to look at the "matter" and to "resolve it in their upcoming updates", send a feedback.
