1000 cycles is about three years of use. I personally charge my EV every night, it's better to form a habit of plugging it in every night than to forget to check it and not have enough energy in the morning.
no, 1000 cycles doesn't mean 1000 charging events will end it. 1000 cycles from 100 to 0% will end it, and if its like current batteries, you get more than say, 10X as many cycles when you only use 10% of the battery per cycle
Once charging/discharge times come down, trickery can be used to turn 1000 into 10,000 cycles easily. If you can charge fast, you can isolate cells alto charge/discharge them individually, only jumping to other cells once the first is full. Essentially, it's wear leveling of batteries as done with flash memory. At the moment individual cells cannot charge/discharge fast enough to fully enable this.
Just checked a relatively new iPhone that is 132 days old. I charge it nightly, even though it hardly goes below 50%. In fact, battery stats for last 10 says that it used on average 40% battery per day, and it is pretty typical usage for me. It has 111 charging cycles.
