MacOs catalina drains battery in sleep (MBP)

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.

I replied to your post the 8th of November, or 14th, and was experiencing the same issues as you described. I have no idea how or why, but I closed my laptop on sunday with a lot of different programs and taps open, and it had only drained 4% over night. From yesterday evening, till this morning - none.

I hope everyone else is experiencing the some improvement in their battery life while in sleep mode.

Yes-- I'm using SSD on a mid-2012 13" MacBook Pro. I can no longer simply close the lid and plan on using my computer a few days later. Power is draining way too fast. Never had this problem until Catalina.

I have exactly the same problem with Macbook Pro 15' Retina 2015 and never had this problem before. I am shutting down instead of just closing lid to avoid drastic battery drain :-( It is so annoying, Apple do something with it, we have paid a lot of money to have functional product.

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?

Hey, i have the non-retina MacBook Pro 13“ Mid 2012 to but with Transcend SSD.

i hoped that Catalina 10.15.2 will fix that but this issue is still there.

In mi case it occurs only when the Macbook Pro is plugged in to energy.

Then it gets hot and will not sleep for 1 Hour. In Battery Mode all is ok.

Also it drains Battery very quick.

I have the same mid 2012 MBP with SSD and boot up from cold into Catalina is now around 30 seconds. I no longer bother with Sleep. Just shut it down.

Study the forum and look out for a number of snags that can keep you busy but once you have Catalina sorted out on that Mac it is superb.

No i have no iCloud photos and it is a fresh installation of Catalina,

without any 32 bit Applications.

When i put the Energy setting to 3 minutes. That work for me.

It occurs only when the Mac is inactive and plugged to energy. Then after 5 minutes

the Macbook gets warm and the fans are spinning for about 1 hour.

If i disconnect the energy all works fine an the Macbook sleeps as it should.

But have you any photos?

Catalina has to re-analyse them. For example you can search for "bike" and it will find all photos featuring a bike. It groups all photos with your face in. Think how much AI is required for that and as already said on page 1 it can process that in its sleep.

New 2019 MBP, drained battery from 100% down to 5% over the course of about 24 hours with the lid closed, not connected to power.

Activity Monitor indicated that Chrome (with about 25 tabs) and Photos used the most energy during that period.

Even if Photos needs to re-analyze all the photos, I wouldn't think it's a good idea to be doing that on battery power when the lid is closed and the computer is supposed to be asleep.

It would be great to have the computer working away on Spotlight and Photos, etc. during the night if it's connected to power, but past experience has led me to believe that it's generally not doing much (and not using much battery power) when the lid is closed and it's not connected to power.

Well, it seems that my Problem is gone.

I had the Problem that my Macbook Pro (Mid 2012) non Retina not sleeping.

After 5 minutes of inactivity and wehe it was plugged in to energy, the Fans begins to be loud

and the Macbook gets hot. The Display gos to sleep but the Macbook works continuously formore then 1 hour.

SMC reset, new clean installation of the System and all other things did not help.

Two days ago i observed that a task called „mediaanalysisd“ is taken 120% of CPU.

This happens only when the Macbook Pro is plugged in to energy and there is no activity on it.

On that moment when i do something or just move the Mouse, this task disappeared from Activity Monitor.

That is the reason i never have seen it before. But nov i put the Computer and the Display to never sleep

and started activity Monitor App.

After that i started Photos App and checkt the People that were found by it.

For some People it still searches sins 3 weeks nov and newer ends, maybe because there is just 1 Face and the App needs more then 1to finish his job. I deleted this persons from People and restarted the Macbook Pro.

And now „mediaanalysisd“ is still there but consuming only 10% CPU and the Macbook is not warm any more

and gos to sleep at the time when i set it in System Energy settings.

If you familiar with Terminal you can use the "man pmset" command to list the flags.

If you are not familiar with terminal then take great care with sudo commands you find on the web!

Also hibernate 25 mode takes as long to wake up from as shutdown in my experience of HDDs

I have changed standbydelay(high/low) using pmset and set tcpkeepalive to zero and it seems to help. I think that tcpkeepalive is the key, you can try in Terminal:

sudo pmset -b tcpkeepalive 0

It seems to affect Find my Mac functionality but battery life it more important for me.

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.

I have the identical hardware and SSD.

It takes 25 seconds to boot up, so why leave it on unpowered sleep (the subject of the thread) for any time at all?

It has all been said before about checking for CPU hogs in the Activity monitor and dealing with them. Also not leaving it in sleep overnight. Charge it or turn it off.

Neither Catalina nor Mojave are particularly good as all day laptops but once photos are reprocessed I haven't notice much difference..
