MacOs catalina drains battery in sleep (MBP)

If I left my mac to sleep on mojave for 3 days it would have run flat too. It is not a hibernate.

When shutting down check the box that says to open up all the windows you had open.

If the Mac is powered on, and that includes sleep, it is draining the battery. If you are not going to be using your Mac for several hours, it is best to just shut it down and hook it up to a charger. That certainly conserves battery.

My 2016 MBP doesn't seem to go to sleep and drains my battery and gets warm when in my laptop bag. In Mojave I would close the laptop, stick it in my bag, and it would go to sleep and hardly drain any battery. Now with Catalina, it seems to constantly stay on and gets very warm in my bag. Battery drains right down pretty quickly when it hardly did that in Mojave. That's what I get for upgrading so soon.

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.

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.

I had a MacBook Pro late 2013, power consumption in stand-by has been negligeable until I updated to Mojave . Since, no way, 10-15% draining per day minimum. Same with Catalina.

I felt it was because it was an old model with a recent OS.

I now have a MacBook Pro 16 , a bot better, but still battery is used too much during stand by.

For me one f the key advantages I found against Windows was the stand by working so well..... I believe Apple should fix what for me is real a problem.

I think you are correct. Hibernate 25 on a rotating hard disk takes many minutes to wake up in my personal experience.

Converting to SSD makes overnight sleep unnecessary - shut down and start up is much less than a minute in both cases.

Follow up: with hibernate mode now at 25, set my 2019 MPB 16 on sleep last night about 10pm, no AC power connection, not other ports connected. Resumed almost 9am. 100% power level. Better improvement than expected. I'm guessing the powering of RAM in sleep mode was what was draining the battery so quickly. I'll trying a longer test, 24 hours, over this coming weekend if I remember.

Just had it in sleep mode for 28 hours straight. Still 100% charge. Looks the hibernate mode 25 worked to fix my sleep drain issue.

I have the same problem. My MacBook is from 2017, and after the Catalina update, my battery drains fast in sleep mode. I used it yesterday till around 5 PM, and it was at a 100 %. I opened it today at 10.30 AM, and it was at 36%. Befor it only lost around 5-10 % in that timespand.

One of the reasons I keep buying apple products, is because of the great battery life, and I really need that in my job. I really hope they fix it soon!

Mine is a MacBook Pro (15-inch, 2018), and I'm also affected by this issue. So it is not only older models that got their battery life borked. I hope Apple gets on the case and releases a fix pronto... :(

I have the overall impression that OS X has been optimised increasingly for SSD not HDD. I wonder whether those experiencing swift power drain have HDD not SSD?

I have nothing to back up my overall impression except empirical experience with my prior MBP and my current one

I have a Macbook Pro 13" (mid 2012) non Retina with an 1 TB SSD and 8 GB RAM

Until i installed Catalina, never had a Problem. But sins Catalina...

Same Problem draining Battery in sleep.

The other Problem is that when i work on it and it is plugged in to energy all works fine.

But when it is inaktive for a wile then the fans beginn to be loud and it is hot.

As soon as i move the mouse or do something else it returns to normal.

That happens only when it is plugged in to energy, and not in Battery Mode.

It is a completely clean Install Catalina.
