i cant pee all the way?

Tmi maybe?
When i go to the bathroom, I often am there for a few minutes playing on my phone. Ive noticed when i pee and im sitting there for a minute, i have to repeatedly squeeze to get all the pee out. Does that make sense? I dont really know how to explain it.
I dont have any symptoms of an infection..
I can also go almost 24 hours before i feel the need to pee at all. 12 hours if im drinking alot. This never happened before
