About overcharging your cell phone?
My dad cell phone. He doesn’t use it a whole lot. But when he charge it. He doesn’t uncharge it for like 24-72 hours or maybe more. Now on his phone his battery is very very very low. Even when he charge the juice doesn’t come up. So could it be because he overcharge it too much?

Yes.
Holding a lithium battery at full charge makes it age and degrade far faster than if it is in use, or stored around half charge.
Heat also makes batteries degrade faster, so if it's being put somewhere warm (or getting hot) whilst connected to power, the battery could be wrecked after just a few months.
Note that you cannot actually overcharge them, the charge control in the phone (or laptop etc.) will stop charging when the battery is full.
Using phones/tablets/laptops as soon as the battery is full, and trying to average around half charge on the battery, gives the longest battery life.
Search "BU-808: How to Prolong Lithium-based Batteries" for more info - it should take you to an article on batteryuniversity.com about getting the best out of lithium type batteries.
