Is it really the battery's fault if it degrades over time even if it's a non-removable battery? or do manufacturers add some technology to prevent this 'plugged in and full' overcharging factor of laptop batteries?

I want to know if it's actually safer to get a removable battery and removing it when plugged in and full, does it actually protect the battery over the long run? or going for a laptop with a non-removable battery is fine and would perform the same?

Its a feature of lithium batteries, they have a finite number of cycles and they don't like being left at 100% charge for long periods. My last Sony had a battery care feature for users who used the laptop mainly plugged into the mains. This feature means you could choose to only charge the battery to 60% or 80%.

Didn't know that. Does it also apply to Lithium Polymer batteries?

D'you think today's laptops have what your Sony's had? Maybe some 3rd party software I could use to prevent from charging when at 80%?
So I could freely choose a laptop with a non-removable battery without worries of fully charging it in prolonged hours.
