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.
Exactly the same here - just running Safari and my MacBook 2019 is insanely hot with constantly spinning fans. This never happened before...
2016 15” MB Pro with the same issue, installed Big Sur and my battery life went to hell and it didn’t charge at all last night. Strangely took a few days to reach this point, not immediately after install. Currently trying the SMC and PRAM resets to no avail.
Hey all, I followed the steps the customer service person told me about clearing the SMC and NVRAM and also adjusted a setting in Chrome and it seems to have solved both the battery draining and fan coming on issue. Give it a go:
Clearing SMC: https://support.apple.com/en-gb/HT201295
Clearing NVRAM: https://support.apple.com/en-gb/HT204063
Chrome setting: Noticed that the Activity Monitor shows Chrome Helper running as the main thing taking up loads of CPU resources. You can force quit it in Activity Monitor but it comes back so you can make it not eat up your CPU it by following instructions on google to disable Chrome Helper. (Note: Chrome still works even if you force quit this in your activity monitor)
Hope that helps :)

When I'm on Safari my fan goes crazy, even when I'm playing a game it isn't this much. Also my battery is charging so slow since the update. It says that 1 and 24 minutes for a full charge when it is 78%.
installed big sur went from a great battery life to watching the percentage fall by the minute (or quicker). This when only doing a little light browsing. no video no complicated calculation.
When battery was highlighted in the beta testing how could Apple do this? It seems their marketing calendar beats any consideration for their users.

run into problems with overheating and battery draining fast since big sur update as well.
checked acitivity monitor, turns out a process named secd is mainly the reason, constantly using my CPU >50%.
found out it is somehow linked to the keychain.
deleting the local keychain and restarting solved the problem for me - no battery drain any more. (read this: waal70blog.wordpress.com/2019/12/16/accountsd-and-secd-high-cpu-usage-on-catalina/). I would only have to type in all passwords for internet accounts and set touch ID again. make sure you use icloud keychain to not lose any important passwords.
anyway, before you do this, check your activity monitor. every new installation forces spotlight to index, wich could also account to high CPU usage. But this should not last longer than a few days.

The same problem after Big Sur, the battery drains after 3-4 hours of use.

Exactly the same problem. Laptop doesn't even last 5 hours now.
MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports)
MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports)
Same here.
My MacBook Pro 15” (2015), would last about 2.5 hours connected to my Thunderbolt Display as I worked.
After updating to macOS Big Sur, I noticed that the battery was draining really fast and decided to use my timer to track how long it would last with a full-charge. Within an 1hr & 26mins my battery was at 16%. It took 4 HOURS to recharge.
I then tested to see how long it would last without the Thunderbolt Display, and just one chrome window open with a YouTube video running. The battery went down to 30% by 1hr.
it’s like a flashback to when people called them out for purposely making older iPhones run slower, and run out of battery faster with the latest iOS updates.

Installed Big Sur 4 days ago and since then
overheating and fan running more often
a process named Kernelmanagerd using CPU between 60 to 70%
battery draining faster than before
battery pref. showing message : "the battery's capacity is significantly reduced. To restore capacity, please check your service options"
I have this same issue after my update, So stupid.. some problem arises update after update. better don't release an update.
Hi,
Macbook Pro, early 2015.
Experienced the same problem with overheating, battery drainage and slow charging.
I have resolved the overheating as suggested by thetorien 2 days ago.

In Activity Monitor sdec process used <60% of CPU. Followed instructions on link suggested by him and resolved the overheating.
Did not resolve the still significant battery drainage (better than immediately after update though!) and slow charging...
My battery status still indicates that Battery Service is recommended.

as per previous post installed Big Sur 4 days ago and since then
Managed to remove the process named Kernelmanagerd by removing Malwarebytes. Now CPU is less loaded, and the fan also.
Battery drainage is partially solved, but I still have the message asking for a change of the battery that has now a full charge capacity of 4823mA only.
Seems that Big Sur has a bad impact on the battery... It reminds me what Apple did with iPhones, when they introduced new iOS that reduced battery lifes...

Since updating to Big Sur, my battery manages to hold for just 4-5 hours (no change in applications being used)! Before I could easily get 10-12 hours on Catalina!!
Also, everytime I plug it in to the mains, it says “battery is not charged”.... APPLE sort this out!

Having the same issue with battery draining on an early 2015 Macbook Air that I got in early 2017. It drained 40% in 2 hours just running Firefox whilst before it would only drain 15% an hour. This is incredibly reminiscent of the battery draining they did with iPhones. Really hoping this is just an honest bug.
