What's the best interval to drink water?

I've tried drinking like 500ml each time, it hydrates me well if I continue it for 3-4 times throughout the day End up 1 day about 1.5-2L

I've also tried sipping 50ml-100ml each time, like it's becoming a habit to get something to sip on, but doesn't seems to hydrate myself well End up 1 day about 3L

So far it seems that the first method that drinks in bulk but with lesser daily consumption, seems to hydrate better (from the color of my urine)
