Updated MacBook Pro to macOS Sonoma, now battery drains quickly

Without wishing to get into a discussion about this major issue. Even with no cables plugged in and in sleep mode battery was going from 100% to 1% with a few hours, plus battery was overheating.

Reinsitalling Sonoma cured issue for 3 days but has now drained battery overnight yet again in sleep mode.

This is a major issue that Apple need to be addressing urgently.

My laptop isn't connected to anything overnight when the battery is draining. It's almost never connected to any peripherals in daily usage (just the occasional external drive).

There isn’t a problem my friend! As I said, if you simply UNPLUG all external cables, your battery will not drain. If you leave cables in overnight, even if what they are connected to is powered down and unplugged, the battery will drain! There’s no problem, no big deal, not complaining, just giving a solution to a problem everyone is having.

The “powerd request=CSPNEvaluation” is new in Sonoma. I guess all Sonoma users will have it? Does somebody know what it is used for? In Ventura I was able to get rid of all wake requests and the machine was sleeping properly! In Sonoma I ended up with the CSPNEvaluation. The machine will not sleep properly as long as this cannot be disabled. Thus it would be crucial to know what it’s purpose is.

Both my Intel based MacBook pros (2018 and 1019) have the same issue after updating to Sonoma. All indexing etc is complete. Before Sonoma all was perfect, but now I can't leave the laptop unplugged overnight as the next day could result in a dead battery.

Yes! That was what I was thinking. Too bad I didnt take a screenshot before upgrading but my untethered battery time was great 2-3 weeks ago. 1w after Sonoma and it depleats within an hour. I only use a few tabs on chrome and edge, a lot of visual studio code and spotify in the background + BT headphones.

Luckily it's my work computer so the company will take care of any repairs but it's still annoying having to handle this battery stress.

Yes, having various battery problems as others here. Won't wake up from long sleep or shutdown without being plugged in. Shows 0% battery, but once plugged in, instantly shoots up to previous charge. Am noticing battery drain, but haven't documented this. Checked battery life recently and it said NORMAL. Now it says Service Recommended.

Since you are having battery run time issues, then this indicates your battery needs to be replaced. Even if the battery condition toggles back to "Normal", it indicates the battery is in a borderline state and will soon be showing "Service Recommended" all the time.

Yepp, I'd agree that even though the battery indicator states "Service Recommended", the actual issue is with Sonoma. I've probably had my Service Recommended status for month or two but without any apparent issue since Sonoma was installed.

I've recently updated my Macbook Pro 2019 to Sonoma also.

During the day I normally work with power plugged in and then close lid at night and remove power. Opening lid in morning would still have had loads of battery power left.

Now on Sonoma I waking up to a dead macbook and need to plug in power to turn on. This also caused issues with the resetting of date/time.

I've tried various setting changes as per other threads with no success, tonight I will try the turning wi-fi off as suggested and see what happens.

Are Apple investigating this??

No - I did not do a disk wipe and re-install. It may be pointing to the background re-indexing that the Sonoma update needed to do as suggested by someone previously on this thread.

That of course is not to say there are other issues that may be causing this for others but the above post was my experience.

With light browsing and web programming I cannot use my M1 for more than 3 hours. The battery drop in the Battery graph (System Settings) is outrageous. I can't do anything but reformat and install the old OS.

@apple please make an announcement when the battery drain has been fixed.

Brand new 16" MacBook Pro M3 Max (running Sonoma 14.1.2 out of the box) - unboxed 3 days ago.

Had below battery drain kick me in the nuts this morning. Went from ~90% to <10% in around 1.5 hours. Nothing significant running at the time.

Assume I had put on max load graphic/computation (again, which I did not have at the time): brand new (and pretty much fully charged) battery should still have longer runway and this (right?)

I've the same issue, but even when its plugged, I used to work on two monitor setup without any battery drain during development all the time while the charger is connected.

Suddenly after I've updated to Sonoma, the battery start to drain bloody fast to 80% and then stay at 80% as long as I've the charger on

Sonoma has a problem regard power consumption and need to be really addressed.

First of all, if you have an electrical socket nearby, plug in the MacBook, before you put it to sleep. Also, have optimised charging mode on. Also,

My MBP is always plugged in, sleeping for ~9-10 hours a day. I rarely use the MBP on battery, but I do sometimes just to check how long the battery will pull. It still does, the battery is quite good. (My MBP is 4 1/2 years old) Time to time, I simply shut it down for the night, when it reaches 100% while in optimised charging. The next day the optimised charging kicks in and within few hours, the battery level falls to 80% and stays there for days.

The macOS takes good care of the charging, especially in optimised charging mode, one doesn't really have to worry.

Updated a couple of days ago to Sonoma, and used my laptop for maybe an hour, left closed in sleep mode. Came back to find it COMPLETELY dead, re-started it, charged it for 15 mins as I needed to move it from one room to another and literally watched it tick from 8% all the way down to 0% in about 3 mins.

My laptop is also now almost too hot to use on my lap - as the name might suggest.
