Yes, Amoled are more oversaturaed, Better battery life- This is because light will glow only in selected parts where it needs to glow and it will remain off in place where it is black ..LCD poor battery life- the whole screen needs to glow when ever screen is on. But the auto brightness will be better in LCD and it will give perfect picture.
Frankly LCD is better than LED because of life span. perfect amoLED is way too costly for manufacturer.
