Are you not worried that permanent, 24/7 connection to the charger, will destroy the battery, make it blow up, swell, or something in that line?

Modern phones have overcharge protection, as long as that's in tact (no reason to think it wouldn't be), it'll be completely fine. The worst that might happen is your battery capacity will degrade slightly faster than it would otherwise.

It's Lithium not Nickel-Cad
