I'm not an expert on the issue, but that's a good number. The original article states it's a cycle life of 1000 charges, that means full charges, say charging from 90% to 100% doesn't count as a full charge. These batteries are tested with 0->100 charges, but other factors affect battery life, like temperature and charging rate. After the 1000 cycles the battery isn't dead, it will just hold partial charge, basically degrading partially over time each discharge. It's basically saying "After 1000 full charges, the battery will only retain 80% of the original battery capacity". IIRC my pixel 3a has LiPo battery and is rated for 300 cycles and from what I can tell lithium ion usually has a cycle life of ~500. edit: Adding link to original article https://news.samsung.com/global/samsung-presents-groundbreaking-all-solid-state-battery-technology-to-nature-energy https://news.samsung.com/global/samsung-presents-groundbreak...
