You can't really generalize cycles based on chemistry alone. Battery management and usage matters. But two examples with NCA/NMC chemistry:

- The Tesla Powerwall 2 battery warranty[1] is for effectively 3650 cycles (daily cycle for 10 years).

- Many cases of Tesla cars at 200k mileage (~1000 cycles, depends on battery size) with less than 15% capacity loss[2].

And these batteries didn't die after reaching the high number of cycles, they just retained less capacity.

Yes, Your phone or laptop though... that we dont have regulations that at least require manufacturers to give users the option to not charge to 100% is beyond me.

Many billions of batteries and thus billions of devices needlessly scrapped.
