- Nobody is talking about storing a battery for long periods at full charge. The OP asked about simply leaving it on charger overnight. His message wasn't completely clear, but presumably what he means by keeping it "fully charged for the new day" is that he will actually utilise that full charge the next day by running it off battery power.Lithium-ion batteries shouldn't be stored for long periods of time at full charge, which is effectively what you're doing by having your laptop plugged in 24/7 (the battery is not cycled)
- Yes, 'cause purposely erasing 30 % usable capacity from day one is so much better than losing those 30 % from natural degradation over 5 years - if it ever even gets that high...I think Apple should implement an option to set "charge limit" similar to how Tesla does it. Lets say you set it to 70% you could then keep it plugged in, but it wouldn't charge above 70%.
Except that is misinformation right there.Fair bit of assumption and misinformation here. Lithium-ion batteries shouldn't be stored for long periods of time at full charge, which is effectively what you're doing by having your laptop plugged in 24/7 (the battery is not cycled).
True. I hear so many myths spread around these days that only apply to old batteries from perhaps the mid-nineties that simply don't apply anymore. Even the most basic lithium-ion batteries these days have software and controllers that negate the need to "condition" them. I'm more than comfortable keeping my laptop (or any other electronic device) continually charged if I need to take it with me at any time.To be honest, like others have said, I don't see an issue with this. I've had my laptop in a docking station for quite sometime, and all is well thus far.
Batteries these days, are so different from years ago...
And I've done absolutely nothing at all on my 2012, it's left plugged in 90% of the time, and have the same health you do. It's a gimmick, nothing more.I highly recommend the Mac App "Fruitjuice" if you want to maximise the health and life of your battery.
I've been using this app on a Late 2013 MacBook Pro, following the guidance every day, and my battery is still rated as being at 96% of its original capacity. I first heard about this app on the Mac Power Users podcast and it really is a gem.
