    Hi,

    I love my Macbook. It is the 512GB m5 version with 8GB RAM. For the past few months the charge capacity on the device has been sharply declining (attachment) and now shows 'Service Battery' on the status bar. I typically would perform repairs on my tech myself but I understand the battery replacement is near impossible on this device.

    Apple wants me to ship my laptop to their repair center... but I don't know what the cost is going to be if at all they're willing to repair.

    How much will Apple charge me to replace the battery?
    What do you think I can get on ebay (or other marketplace) for the device?

    Any other info/experience is appreciated.

    Do you use Windows(Bootcamp) on your MacBook? Looking at your attachment there must have been some changes in the way you used it at the end of 2018/early 2019.

    I used to use bootcamp. No changes in late 2018 on how I use my Mac.

    So here is your answer for the battery issues. Apple should have said that they guarantee 80% battery health at 1000 cycles when using macOS only.

    Depends - in the US it is $199 (https://support.apple.com/mac/repair/service). I don't see why they would refuse to replace it. There is a risk, though, that they find other "damage" that they absolutely have to fix before they are willing to deal with the battery.

    I think that's jumping to conclusions. They guarantee that performance only within the warranty period anyway, so from that perspective the battery was behaving within specs. Differences in usage will affect the lifespan of the battery in different ways. I'm pretty sure one could burn out the battery using macOS if one really wanted to. In any case the user's applications are way more likely to affect the battery than the OS itself, which is designed to be in the background, after all.

    Apple is just being smart about their battery warranty. Apple batteries can easily last 2000+ cycles at 80%+ battery health. The 55% battery health at 440 cycles is bad even for a cheap knockoff battery. From my experience, Windows with bootcamp is a sure way to knock your battery's health to 25-50%.
    Do you have a personal experience of running bootcamp with Windows on your MacBook? How's your battery health?
    I am sure that "in theory" the OS does not matter, however practical experience shows otherwise.

    This might be the case in general but not in my usage. I haven't used Bootcamp in years and the battery was great when I did. Battery life took a nosedive in the last few months.

    Thanks for the info. Not sure if it'll be worth paying $200 for the repair. Good point on the alleged 'other damage'. I'm sure they're going to try to sneak that in there for a ding or two I have on the casing.

    How did you use your macbook? Did you often run it down to 0% or do you always keep it plugged in... or?
