A phone blowing up is slang for getting a lot of calls or texts.
B*tches be blowin' up my phone hella much.
I only get calls from mah shorty.
I do not play that.
You can't take an iPhone on an airplane because they tend to catch fire. Or so I have heard. I guess you might call that "blow up", but it's not the same as "explode".
If you charge them from 220V AC mains with a charger intended for 110V AC the battery will probably grow very hot and it might even explode if you leave them 'charging' too long.
Ditto for any other Hi-Tec you may have with rechargeable batteries,
