The 18 hours from Mac Book is also manufacturer specificied, and if random reddit comments are proof of widespread malpractice then here: https://www.reddit.com/r/macbook/comments/1d6jtuh/battery_problem_on_macbook_pro_m3_pro/
Who are you bullshitting, lol, literally in the comments it says it’s the fault of a third party app.
I have also done more than 18 hours, so I don’t care about manufacturers specification, since I do have first hand experience, which you might dismiss as anecdotal but the thing is, I don’t care.
How long did it take you to find that reddit thread with the whole ass 3 comments btw? Lol
So my random reddit thread is bullshit and obscure but your random reddit thread is legit and relevant?
