Sorry I have studied this in other language and I not even sure how these things called in English. There is one graph that I remember called Woehler curve and there is another one that shows how much is the life expectancy operating between different charging levels (which I cannot find the name for). https://www.researchgate.net/figure/Woehler-curve-for-lithium-ion-battery_fig2_275258416 https://www.researchgate.net/figure/Woehler-curve-for-lithiu... Update: It is called SN curve: https://www.researchgate.net/figure/SN-curve-applied-to-battery-lifetime-estimation-Number-of-cycles-in-function-of-depth-of_fig7_249322820 https://www.researchgate.net/figure/SN-curve-applied-to-batt... It shows a bit different picture for Li-ION that I remembered.

The reading I did years ago stressed that you should definitely cycle batteries to as close as Zero as possible, but if you want to do long-term storage keep them at 40%. Seems like there is a lot of myth around how batteries work and proper practice. A unified resource on this would be great!

  Depends on the battery chemistry. NiCd and NiMh batteries which were very popular 10+ years ago do have a memory effect: https://en.wikipedia.org/wiki/Memory_effect https://en.wikipedia.org/wiki/Memory_effect LiPo batteries do not have a memory effect, and you should avoid deep discharges.

  I think the linked study gives you some insight. The problem is that we need all the capacity we get using a mobile phone for example. You can't really have a 2x capacity battery just for the ideal life time unfortunately.
