My laptop's battery wear level was 0.1% in March and is up to 3.8% today. Is that considered an acceptable deterioration rate?
I noticed that deterioration happens only if I leave it to drain for too long. It's not gradual deterioration in capacity.

It happens also if you keep it 100% on charger.
Some laptops have option in bios to keep charge ~%80-90.
Batteries also hate to be hot, they deteriorate much quicker.
