Yeah, can someone who knows how this shit works chime in? There's a lot of conjecture on the internet but few answers. Apple's advice seems to be "don't worry, be happy, don't let it be in a discharged state for a very long period of time, occasionally cycle through it".
I'm on my third battery for this 2009 Macbook unibody (granted, the first one was water damaged but still…), and 300 cycles in it's starting to give me Service Battery warnings and I must be doing something wrong.
- kalleboo 13y agoThere seems to be no exact science with Li-ion battery life. Even defining "life" is difficult, since some people say the batteries "life" ends at 80-50%. Of all the things I've heard about Li-ion batteries, the only ones that haven't been refuted are: - Li-ion batteries like living at around 70%. More or less will decrease their life - Li-ion batteries will always lose 30-50% capacity in 3 years even if they're just lying on a shelf due to their chemistry - Li-ion batteries dislike heat. More heat reduced battery life. Coldness will temporarily reduce capacity, but has no long-term effect on lifespan.
