> Isn't it an inherent problem with phones that if they are left on charge forever that their battery will explode?
Not necessarily, it depends on how much care went into making the phone.
Ever since Samsung had the unfortunate experience of having every airline announce that their phone wasn’t allowed on board (even when switched off), battery management has received as much attention as is possible. Most implementations today have multiple fail safes in place to prevent the chances of a battery exploding.
Today, several extremely improbable events must happen in a row to make a battery explode from just being connected to a charger 24x7.
