You shouldn't worry too much about going below 40%. Regularly draining it to zero might shorten battery life, but going down to 10-20% won't.

From Apple's perspective there is. Selling replacement batteries is very profitable.
- grepfru_it 3y ago10-20% will definitely reduce cycle life. you would almost double your cycle count by keeping your battery above 40% vs 20%
- Reason077 3y agoThis has far less effect than limiting charging to 80%. If only because you usually spend a short time down at 10% before noticing it's low and finding a charger. Where as phones regularly spend long hours charged to 100% because we tend to put them on chargers and then leave them overnight.
- stealer0517 3y agoCycle count is virtually meaningless. I have a MacBook Pro with almost 1000 charge cycles and it’s got ~93% battery health after 8 years. Lithium batteries are happiest around 40% state of charge. The closer you can keep them to that magic number the longer they’ll last. But leave them fully charged, or even worse, fully dead and that’s the quickest way to kill them with “normal” use.
- Reason077 3y agoThat's very impressive! My Macs are usually down in the 80-85% range after 500 cycles. Do you use any tools to limit charge state other than "optimized battery charging"?
