Install for Improved Battery Monitoring

If you like the take your Mac on-the-go, you might enjoy the battery monitoring upgrades Apple's made in macOS Big Sur. 

macOS Big Sur comes with Optimized Battery Charging which Apple says is designed to "reduce the wear on your battery and improve its lifespan by ensuring that your Mac notebook is fully charged when unplugged."

The software learns your daily charging routine and activates only when your Mac predicts that it will be connected to a charger for an extended period of time.

macOS Big Sur also includes battery usage history which shows you graphs of battery level and usage for the past 24 hours and the past 10 days. 

If this sounds interesting, and you're still running macOS Catalina or an older version, it might be the time to make a move to macOS Big Sur.

    Big Sur is terrible. My computer runs so much slower I’m ready to throw it out the window. Don’t download this program.

    cannot maintain connectivity of screen share. One or both of us lose screen control. constant disconnects and frequent reboots. covid forced at-home business is getting impossible with Big Sur.

    I have a brand new 2019 MacBook Pro and my partner has a fairly new 2016 MacBook Pro. We were doing just fine on Catalina then switched to Big Sur and everything went to hell…we gave it a week to settle in with all of its syncing and updating stuff but then found that performance issues and bugs like entire system shut downs and black screen and spinning wheels started happening… this is supposed to be the best hardware we can buy and yet hampered by Big Sur and its issues is causing us to rethink going back to Catalina.

    I have a MacBook Pro 2016. Big Sur automatically updated and as a result I can no longer use the MBP as a clam when connected to my BenQ 2700 monitor that I need for photo editing. When I try to log into my MBP in clam mode the screen goes blank after about 10 seconds and says it is not receiving a signal. Seriously! This latest update was supposed to sort a few things out for 2019/20 MBP …. not f**k a 2016 model… Unbelievable. Thanks Apple..

    Big Sur update 11.2.1 and now 11.2.2 will not update on my iMac (Retina 4K, 21.5-inch, 2019) It seems to download but when installing i get a error message that there is a problem with my internet connection.

    I have updated my MacBook Air late 2020 to 11.2.3.
    Can’t really see any difference. Since I bought the
    new MacBook the only problem I’ve had (which is very
    annoying) is that the auto login option is greyed out
    and I cannot disable the automatic login. In Library/
    Preferences the com.apple.autologin etc. is missing.
    Surprisingly enough I installed MacOs Catalina on my
    old MacBook Air mid 2012 and it works perfectly.
