Thank you very much, my problem has been solved.Just use the official instructions.
There are a lot of videos on Youtube as well. As the Sonoma is pretty new, I generally recommend to wait a little and go with Ventura for now. For that
- Install OpenCore Legacy Patcher 0.6.8
- Create Ventura installer on USB drive (external SSD/HDD or just 16+GB USB stick).
- Enable "Disable Firmware Throttling" feature before building and installing OpenCore!!! This is the one that prevents the battery issue discussed in this thread.
- Install OpenCore EFI on that external drive.
- Reboot and hold 'Alt' while booting to choose EFI loader. Effectively you will be using non-native loader to bypass built-in checks that prevent installing newer OSes on older hardware). Macbook will remember the startup partition for the next boots, so you won't need to pick EFI anymore during installation.
- Select "OS installer" or whatever it is called to install the new OS.
- During the installation your screen will go black for a few seconds (less than a minute). Then will go back. Expect small fonts, this is normal.
- Once the OS is installed, install the OpenCore on internal SSD. This is for you to be able to load OS without the external SSD.
- Reboot to check that EFI on the internal drive is working.
- Install "Post-install patches". This is drivers back ported from old OSes into OCLP which are missing or not working in the new OS.
I confirmed that the battery issue totally gone on multiple laptops. Maybe there is a way to enable this "Disable throttling feature" in the native OS, but at this point I don't see a reason to not use OCLP.
The mid-2015 15" Retina MBP is now considered vintage on the apple site. Has anyone found an aftermarket battery that doesn't cause these symptoms?
Go to an Apple Store, or order a mail-in repair through their support website.

I had the battery replaced 6 months ago in an official store (end of 2023).Apple stopped doing repairs on this model in 2022.

I suspect that it was for the whole top case replacement. I remember that they ordered the part from some storage facility, then called me to let me know that I can bring the macbook into the shop for the repair.They told me that they had no more kits left. Did they just replace the battery or did they also replace the top case, keyboard and trackpad?

Also, you can go to this link (https://support.apple.com/15-inch-macbook-pro-battery-recall) and see if you can get your battery replaced for free.
Just search for most expensive one on Ali to reduce risk, or find shop wich is selling only batteries for professional power tools like m feng tool store for example , from where my battery comes and is not causing any problems ( correct temp, simplo, one quirk is that manufacture date is old which could confirm that they are using original refurbished controllers )The mid-2015 15" Retina MBP is now considered vintage on the apple site.

iFixit batteries don't have these issues. However, they do swell up in about 2 years if you never disconnect a charger. As did the original battery for me, to be fair.The mid-2015 15" Retina MBP is now considered vintage on the apple site. Has anyone found an aftermarket battery that doesn't cause these symptoms?
