MacOs catalina drains battery in sleep (MBP)

Same here, just bought new MacBook Pro 16, and it drains off battery from 100% to 15-20% for a single night..

one of the thing I did like about Mac Books East precisely the ability to close and open the lid for days .....

If Apple doesn’t fix it, I will be very disappointed

I've never been able to do that in 8 years

That's interesting.. Unfortunately I don't use the Photo app, or even have any photos I store in iCloud!

Thats interesting.

Have a MacBook Pro mid 2012. Check battery is normal. It loses all battery life overnight, while in sleep only after updating to OS Catalina.

if you have (eg) Photos with a reasonably large number of them, it runs a task to analyse faces. memories and other stuff. Catalina has given us a huge upgrade (in terms of needing to reanalyse Photos) and this may be the task that is draining your power, despite the fact that this task states you need to be connected to power for it to run. I'm using it as an example of a possibility, with the suggestion that all may calm down after a "while"

Glad that you found a solution for you :-)

But on the Macbook Pro mid 2012 non retina there are no Power Nap settings

in the Energy Settings.

this Settings came out with the newer Macbook pro Models.

I've configured the Mac to automatically turn off WiFi when going to sleep. I've done this with Better Touch Tool.

I closed the Macbook on Wednesday evening and opened it on Monday morning. Result: Battery changed from 79% to 53%. That's less than 5 percent points per day. That's a great improvement for me.

But there's still a loss of 26 percent points. This seems to be related to unnecessary wakeups by events, although I have disabled everything I could find. I have to do some more investigation here.

Hey, i have the non-retina MacBook Pro 13“ Mid 2012 with Samsung SSD. The Standby Mode does not work on Catalina. I tried a clean install, an PRAM and SMC Reset. The white light on the front does not go off. After that i installed Mojave again and now everything runs perfect. The Standby Mode starts without any Problems. But i want upgrade to Catalina. Has anyone tried Catalina 10.15.2?

I haму the same problem. And it's look like Catalina ignore Power nap Off function. Two days ago my MBP 13 2018 overheat in my bag. I checked the internet traffic and it's look like it try to download updates OS X all this time.

Now my notebook loose 10-15 % of power per hour. And body of laptop all this time is warm.

Tonight i turned off wifi, when my battery was 16%, and after 7 hours it was 14%. It's look fine.

My another MCB 15 2013 has open a lot of programs and turn on wi-fi, but not loose the power. OS Mojave.

UPDATE for battery life after upgrade to Catalina

Hi guys, I am coming back with an update about battery life after 3 days of Catalina. As I mentioned earlier, right after the upgrade (installing Catalina on a separate APFS partition alongside High Sierra) my battery drain was quite high during use, but it turned out that this was only during the process of the OS indexing after the new installation.

Starting the second day, the battery drain during normal use is similar to High Sierra. Yesterday I used my MBP a bit heavier than usual (email, documents, installations, settings, youtube, data transfers, downloads, etc.) and managed to obtain a slightly better than 5 hour of battery life from 100% to 1 % (5:15 hours actually).

Today I used the mac only for surfing the net, email, watching youtube videos and using the MS Office apps (no photoshop, app installations or any resource-hungry activities) and my battery lasts even better times. With normal use it seems that I have juice for 7 hours, which is great for a 5 year laptop that it has been used heavily since day one. (my battery is at 384 cycle out of 1000 and it shows 87% of it's factory capacity)

However, I must say that I take good care of my battery since day one and I pay attention to have discharging cycles from time to time in order to keep a healthy battery. I have a powerful tool for this, an app called FruitJuice which overlooks my usage habits, calculates the discharging times necessary for keeping a healthy battery and reminds me to use my MAC also on battery from time to time. Otherwise I am tempted to use it mostly in clamshell mode, connected to power outlet with my two huge apple displays. Keeping a MBP always connected to AC power is the best way to destroy it's battery in a short time. I made this mistake with my previous MacBook Air.

As the battery drain during sleep issue, setting the sleep type to deep-sleep (25) turned out to be the fix for this. And I had a pleasant surprise to find that with deep sleep mode, Catalina wakes up very fast compared to previous OS versions, it is almost instant after opening the lid. So I close the lid with 100% battery and after 12 hours at the opening I still have 100%.

This you can obtain by opening Terminal app and copy/paste the following code:

"sudo pmset hibernatemode 25"

You cand verify in which sleep mode is your mac with this code: "pmset -g | grep hibernatemode"

Usually by default the sleep mode has number 3, so if you want to change back the sleeping mode to what it was initially, use the code: "sudo pmset hibernatemode 3"

I hope the above describes fix and solutions are helpful at least for a few of you guys, I decided to write down my experience because last time I had these kind of problems I spent many days looking for a workaround and it would have been very helpful if I could find these things fast and would have not lost so many precious days.

Regards!

UPDATE - I had to abandon Catalina because of the all 64bit infrastructure!

As I described earlier, I managed to stabilize the battery drain issue in Catalina with a few tweaks and I was very happy thinking that finally I can upgrade from High Sierra to a newer OS. However when I started to use my Catalina installation to real life work came my second and biggest disappointment because the lack of 32bit app support.

I also support 64bit transition because all the obvious reasons, however it seems that the world is not ready yet for an all exclusive 64bit environment. To tell the truth, I was not expected a fully 64bit system to have such a big impact on my day to day work. As it turned out, most of the apps I use for work has no 64bit support or I need to buy a new license for a newer version in order to be used with Catalina and spend a ton of money, just because Apple decided to make this move. For example MS Office needed a new version, very hard to find, many Adobe apps lack in 64bit support, even my latest launched Brother Printer and Scanner is unusable. They recommend on their website to try to find different third party apps in order to scan or print, because they are not developing support for 64bit.

Therefore I am back once again to the stable High Sierra and will use it another year, or until Apple decides to offer support for such problems they created, or the app developers decide to develop 64bit versions for their apps.

If you want to upgrade to Catalina, I recommend to be extra careful and analyze comprehensively which apps do you use most for work and if that app is 64bit or has a 64bit version, before the upgrade. Big chances are that apps you rely on for work are not yet Catalina compatible. I certainly not recommend upgrading to Catalina if you use your mac for work. I would not imagine simple things like printing and scanning not working on a 2019-2020 launched MacOS and that the latest generation printers have no 64bit support.

Pretty shame...

That was windows hibernate. It wrote the session to disk and all but shut down. Windows sleep still used power from what I remember from work. You can do much the same thing by checking the box before shutting down MacOS. It will make you save open files of course.

There is also hibernate 25 mode if you want to try it.

Both shutdown and hibernate 25 are slow with old spinny disks

Thank you, but prior to Catalina this draining was insignificant. I could leave my Mac sleeping for days with only few percentage of battery drain. Now it completely drains off my battery overnight. This is absurd!
