In 2016, I bought a MacBook Pro, which is still my main work tool and a reliable companion when traveling and at home.
Over the years, it has gone through a lot – from fixing a broken button on the keyboard to a complete replacement of the screen, topcase and battery. The battery was replaced at an authorized service center as a free bonus in pursuit of the fix jamb with an erased oleophobic coating on the screen.
I will say right away: there is not a single compelling enough reason to immediately get rid of my “bug” and run after a newer MacBook model. I am completely satisfied performance, screen brightness and battery life.
Especially the battery life. Not a single Windows laptop stands next to my rugged laptop that can run all day without an outlet.
But recently there was a disaster called macOS Big Sur. Because of this new operating system, my MacBook turns into a pumpkin 3 times faster.
Has Apple betrayed me?
macOS Big Sur is beautiful. But I will give it up.
What do El Capitan, Sierra, High Sierra, Mojave and Catalina have in common? I will answer – on all these versions of macOS, from 2016 to 2020, my MacBook showed miracles in battery life.
I got so used to the possibility of my “proshka” to work 6-7 hours away from the outlet that I stopped carrying a charger with me to the office. Why bother when a laptop is enough for an entire working day?
My use case for the MacBook Pro includes a constantly running Chrome browser with a bunch of tabs, playing music in Apple Music, sometimes watching videos on YouTube, and of course, constantly open instant messengers Telegram, Skype and the web version of WhatsApp.
I also periodically cut videos in the same iMovie. It does not take too long, but this process eats up several percent of the battery at once. And that was not scary.
And then I installed macOS Big Sur for myself. There are so many new things – widgets, performance, new wallpapers, уииии.…
My MacBook Pro has official macos, not beta.
The official release of macOS Big Sur took place on November 12, 2020. The operating system can be installed on the following models of Apple gadgets:
▪️ MacBook 2015 and newer
▪️ MacBook Air 2013 and newer
▪️ MacBook Pro 2013 and newer
▪️ Mac mini 2014 and newer
▪️ iMac 2014 and newer
▪️ iMac Pro 2017 and newer
▪️ Mac Pro 2013 and newer
I have not yet the oldest MacBook, so I have to put it!
I trust Apple. The new operating system is good, and besides, my gadget has the ability to install it. Everything always worked as it should, I haven’t felt any dirty tricks since 2016.
Set. And my laptop was blown away by battery life from 7 to 3-5 hours.
What? We didn’t agree that way, Apple!
Could it be the laptop itself? Unlikely
My MacBook Pro 2016.
The curious reader might think that a decrease in battery life is a logical result of wear and tear on this element, which in general considered a consumable and has its own stock of work.
Yes, if the battery was in my MacBook Pro from the factory and worked all these years since 2016, I would agree and not blame macOS Big Sur for the deterioration of battery life.
But in the middle of 2018 I replaced the battery with a new one… So at the moment the resource of this spare part is still hoo!
My battery parameters. Still fresh, according to table от Apple.
Apple’s support site has table with the maximum number of recharge cycles for different MacBook models. According to her, my battery is exactly in the middle of its life path.
I installed macOS Big Sur from scratch. That is, he formatted the laptop so that there were no “tails”. Of course, just in case, I reset the NVRAM and SMC parameters.
The applications that I use are all official: an office suite from Microsoft and Photoshop. Constantly updated and always up to date.
So I have no other versions except one: macOS Big Sur is to blame for the fact that now I increasingly began to carry a power supply with mebecause the laptop can run out of power at the most inopportune moment.
What are the options for solving my problem
Time to rollback on macOS Catalina.
In fact, I only see one way to fix it. Now I will add this text, reboot my laptop, go to the service menu, format the SSD and install the previous macOS 10.15 Catalina from the flash drive, with which my “firmware” worked confidently for 7 hours without recharging.
And I’ll leave Big Sur alone until better times. Until the very days when a new MacBook with an M1 processor appears in my life.
Every year, with the release of a new operating system from Apple, I was among the very first enthusiasts to install, test and enjoy a fresh macOS. I have never had any complaints about the autonomous operation of a laptop, until today.
Therefore, I want to warn all MacBook owners from 2013 to 2016: consider whether you need to update to the latest macOS? Are you ready to come to terms with the reduced battery life of your work tool?
Of course, I can be wrong, and this is an exclusively isolated case, I just had no luck and something went wrong, it was crooked, and so on. If among you there are owners of old MacBooks, share your observations on battery life after upgrading the operating system to Big Sur.
My 2013-2016 MacBook is working
- on Big Sur, the autonomy is the same
- on Big Sur, autonomy has deteriorated
- Not sure yet
- not updated to Big Sur and do not plan to
24% on Big Sur, the autonomy is the same
30% on Big Sur, autonomy has deteriorated
18% Not sure yet
28% not updated to Big Sur and do not plan to
