This is great. The main reason people change phone in the last couple years has been for battery degradation and screen breakage. Changing those for many people is not an option because is not really possible to get the same quality parts as OEM afterwards.

Also because of flash memory degradation. You may notice that older devices are slow even after a full factory reset. The memory chips are reaching their limits.

Flash memory doesn't slow down as it ages.
