Hi, I installed and update the macOS Big Sur latest available beta and after installation is done, It is showing me battery service required warning in my battery icon, My mac is new and it's been hardly 5-6 months and used casually.
After Installing MacOS Big Sur latest beta update, My mac is showing battery service required warning in battery Icon.
Macbook Pro 2015
Big Sur installed on Friday and the battery drains to 50% in 70 Mins, and overheating as well as extreme RAM usage for small applications.

Same here (MacBook Pro 13' 2019), it's a BIGGG issue.
Same here. Battery life went to 2 hours after update.
Installed Big Sur last night on my 2020 macbook pro 15 inch. Had it at 100% charge this morning upon waking up.
After taking the laptop off the power supply, my battery percentage went from 100% to 75% in a matter of seconds lol. 5 minutes later, here I am at 65% left on my laptop complaining how poorly this Big Sur OS is handling the battery and RAM.
I am now receiving a "Service Recommended" for the power source: Battery. Obviously I am not going to do that, given this is a brand new laptop.
Apple fix your shit.

Same problem here: the more we mention it, the faster we may hope Apple will do something to fix it.
My MacBook is overheating after I downloaded Big Sur yesterday night. The battery empties in no time at all as well.

Same problem here. Installed last 3days ago and my fan is too noise and already done smc reset still i have the same problem and with my battery it drains so fast like full charge it midnight and when i woke up it goes to 75%. Apple needs to fix this.
I'm having the same problem. I updated my MacBook yesterday morning and the battery dies within three hours even if I'm not using it. I can't make it one hour without my battery draining by 50%. Please fix this, Apple.
Same here, I have noticed since d/l Big Sur the battery is draining a lot faster on my recently purchased MacBook Pro (15-inch, 2019).
I also had a few other problems which have mainly been sorted since resetting the SMC, i.e. upon opening a web page it always gave the message "you are not connected to the internet" (but I was), and, fingerprint stopped working. The problem with Apple is they obviously don't test rigorously enough before releasing these updates, and, the problem with me is, if it's new I just HAVE to have it, so I go on full steam ahead but I should check forums first to see if there are any problems. DOH!

Post upgrade to Big Sur, my battery draining like anything. It only last less than 4 to 5 hours.
It used to last for more than 10 hours with 10.x.
Please fix it ASAP

This is absolutely not okay! I can not even use my MacBook as a portable device because the battery only lasts for 2-3 hours before I have to charge it again! With Catalina it used to last at least 8-10 hours! This is absolutely crazy! This needs to be fixed as soon as possible. Sorry, I can't take Big Sur seriously.
Same problem, as i installed Big Sur... the fan is constantly running and battery drained very fast. Apple please fix it ASAP.
Same issue. Posted it earlier as well. Totally ridiculous and now on a restart the laptop takes abnormally long time to boot up. The status bar just creeps along. I want Catalina back. This is ridiculous and if you look back at forums in the beta in July. SAME issues and yet still not fixed
Need some help!, 2-3 battery hours, fan is working always and some slow functions like the internet: slow sometimes like a 90`s modem. I appreciate the support.
Resetting SMC solved my issue with not charging and not recognized charger - https://support.apple.com/en-ca/HT201295
Shut down your Mac.
On your built-in keyboard, press and hold all of the following keys. Your Mac might turn on.
"Control" + "Option" on the left side of your keyboard
If your Mac is on, it will turn off as you hold the keys.
Keep holding all four keys for another 7 seconds, then release them.
Wait a few seconds, then press the power button to turn on your Mac.

Exactly the same problems, battery drains in 3 hours, wifi and LAN connections unstable. I need to know when will the update with the fix be released, if not I would have to go back to Catalina. Not ok Apple.
facing the same issue, and resetting SMC did not resolve the issue. Moreover, the password screen is showing a different battery percentage than the battery percent used on the desktop. Weird. I hope Apple will provide a prompt solution to resolve it.
Facing battery drain issue on my MacBook after Big Sur installation. Apple support team is also of no help.
70% battery is draining to 0% from 9 PM to 3 AM that too in sleep mode. If anyone is having any solution please help.

Have the same problem, since I installed Big Sur the battery drains after 3-4 hours of use. It can stay up to 8-9 hours before this update!!!
My Mac won't charge after updating (( I see "Battery is no charged" or something like "17h 15m until fully charged".
Macbook PRO 2017 15"
Same problem of battery and Fan.
With Catalina :
I called support and they told me to change the battery !
SMC reset with no effect. It's a joke.
Same problem of battery and Fan.
With Catalina :
4. hours with on battery
1 hours to charge it
Fan at full speed with more than 90% CPU
1 hours on battery
2 hours to charge it
Fan at full speed with more than 30% CPU !!!
Service Required on battery
I called support and they told me to change the battery !
SMC reset with no effect. It's a joke.
My battery is is draining fast compared to Mac OS Catalina ! ! ! ! "
update.
two hours on phone with tech. Couldn’t solve it. Said they have no idea. Aware of the problem Has to be sent back to them to try and fix. And will wipe it clean and restore to Catalina. Can’t be done at apple store. Total BS. And no idea how long it will take. Great! No lap top for who knows how long. Gee. Guess if you work or are a student you’re pretty much screwed All because of Big Sur. Don’t touch it. It’s a mess. So if the fixes on this forum don’t work for you this is your fate.

I'm getting the same issue on my 2015 Macbook Air. Fan is running nonstop and battery is draining really fast. Any ways to resolve it?
MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports)
I installed Bug Sur, and instead of 6-7 hours on battery, battery drains in 1 1/2h - 2h.
Please fix that.

Somehow I believe this is connected to the new M1 Macbooks and how bigSur is optimised foi their improved battery capabilities...
