OS Catalina, short battery life on MacBook Pro 15" - 2016

Same problem with similar age MacBook pro, except that my problem started with Mojave. See the following thread (and similar ones) for reports of the same issue, a whole OS version earlier. No response from Apple at all. https://discussions.apple.com/thread/8553128

I just updated to Catalina 10.15.04: Here is my battery status as I make this post:

I have a MBA 2017, I was running MacOS HS until I decided to upgrade.

So far I do not see any battery drain problem for my laptop and the performance is the same.

What I did to prepare the update:

1. I updated all my apps to latest version before updating the OS.
2. I checked if all the apps are 64bits and uninstalled the 32bits apps.
3. I charged my battery and left my Mac on the charger. The process took around 1 hour to complete.

I have two Mac laptops on my kitchen table:

MacBook Air Early 2015, 4GB Ram, 128GB SSD, original battery

MacBook Pro Mid 2012, 16GB RAM, 500GB Hard Drive, new battery, calibrated, < 20 cycles

Both are running Catalina 10.15.3

I just unplugged them both this morning at 7:00 AM. It's now 11:00 AM.

The MacBook Pro had some light use for 30 minutes. No use on the Air.

MacBook Air: 64% remaining

MacBook Pro: 5% remaining

The MacBook Pro is burning through the battery almost three times as fast as the Air..

• I noticed the MacBook Pro hard drive never spins down
• The MacBook Pro has a lot more software installed. However, both systems have the latest Microsoft Office suite.
• Both systems showed CPU idle of around 95% in Activity Monitor, however the MacBook Air was a percent or two more idle.
• Bluetooth is off on both systems
• The MacBook Pro has Adobe Creative Suite installed, and DropBox and both are using a small amount of energy. Those are not installed on the Air.

Nothing showing in activity monitor would account for the huge difference in battery life.

Does anyone have any suggestions for experiments to try?

Issue remains in 10.15.5. I can confirm this too. Can someone help with using pmset commands to kill scheduled tasks. The task com.apple.alarm.user-visible-com.apple.remindd.time-alarm seems to be waking up my Mac every few seconds. Apparently this is related to the reminds app.

The drain is significantly reduced if I turn WIFI off and sleep. If someone can please help with how to kill scheduled tasks that would be super helpful.

Im having similar problem. I have 2015 MacBook 12'' & battery drain has been ridiculous! When I contacted support, they blamed it on Chrome. My battery was replaced few months back so its not the problem. My battery shows normal & cycle count is 276.

I put my MacBook to sleep at 100%, just opened it & it was at 51%. In the 3 mins to open browser & type this comment its down to 46%. Thats Catalina! This is ridiculous! How can i got back to Mojave??

Just looked into downgrading & Apple makes it nearly impossible since I didnt have time machine set up.

10.15.1 dont mention anything about battery so im not going to update. wish i never updated to Catalina in first place. new morning & woke up to 38% from full charge last night.

I'm also having the same problem with my 15 inch MacBook Pro 2017 edition. I updated to 10.15.1 and the battery life seems to be a tiny bit better, however it is not close to Mojave. I got 8 hours of battery in Mojave with same usage and behaviour and now I'm only getting max 3-4 hours. Apple have to fix the battery problem!

I own a 2018 MacBook Pro (w/ the Touch Bar) and I am also having issues with the battery. I have never had issues with the battery life until I upgraded the software a few days ago. Since then my battery life has really shortened and I can't believe how quickly it can go from 98% to 40% - in a matter of minutes. I would like to know how to address this issue. I just completed a SMC reset but I notice no changes. I have been worried about this because I use my Mac for everything school-related. Any advice would help.

Same issue.

Mine's MacBook Air (13-inch, 2017). Battery life down drastically after Catalina upgrade.

Cycle count is 374, which I'm assuming is higher than the rest of the posts here, but my battery life used to be significantly higher. At 56% charge, my Battery Monitor says it's going to last 1 hr 45 mins. It's a joke compared to what it used to be earlier!

its obvious that its Catalina update but Apple still hasnt put out update to fix it. this is the way Apple works. Force device updates that drain battery forcing to get new device. Tired of waking up to a battery with 30-40% after putting it to sleep night before at 100%!

FIX IT APPLE!

Seriously, are we sitting ducks now? There has been no hint that Apple has acknowledged this issue. Will the next update undo this battery damage, or is it going to continue this way? At least if Apple would respond as to which background process is taking such a toll on our existing battery life!

If anyone has gone to Apple Care and found a solution, please update here.

I purchased a new 15in MacBook Pro in September. I loved it! It was my first Mac and it worked great! I upgraded to Catalina 3weeks ago and hate it! I cannot go more than 2.5 hours without draining to 0%. Honestly, my old Dell computer battery stays charged longer and that’s saying a lot! I hope Apple fixes this issue soon, I am taking my computer back to the Apple store tomorrow and I am crossing my fingers they can help. As of now...I am having to use my Dell if I need a computer for more than 2 hours.
