Is that supposed to be good xD? Because it kills your device.. You think its good while its really no good.. iPhones have very limited specs, they're not like androids.. With the progressing of time they don't stay relevant and the new software updates slows them down heavily.. Its just a scam to make you upgrade then you would be faced with a turtle kind of device, then you open your wallet and buy a newer device.
I agree that other OEMs need to up their game when it comes to the duration of support.. But not like Apple.. OEMs should support the devices with updates as long as they can handle them.. Now Apple doesn't do so.. They give you the update KNOWING that it will slow down things for you..
