Does battery life get affected if you charge Iphone constantly?

Is it advisable to charge iphone only after its battery completely finished or is it ok to charge it to keep it always full? Does the battery life get affected with charging it constantly?

Those types of batteries have a certain number of charges, so yes don't constantly do it. It should last a couple years even if you charge every day, or longer if you don't. Just wait until % shows 10 to 20, then charge it. The battery will deteriorate no matter what you do.

I usually charge my phone only when it says "low battery"
because I don't constantly worry about the friggin' thing.
