Lite a fire in a pit,put Jacob Sartorious Sweatshirt on,trust me,it will be in the firepit in seconds.
Get a a LIVE atomic bomb and out the phone on top. Then detonate the bomb while you stand 100 feet away. No more phone forever .
Since you live in Michigan, you might not be too far from a body of water. Make a raft from a napkin. Put your phone on the raft. Get to a river. Light a match and set the phone on fire. Let the river take it away. It is easy.
Then pour water on the exposed lithium. If I remember my chemistry right, because lithium is a group I element, it reacts rather violently. Overcharge the heck out of it!! It explodes.
Microwaves have metal in them, that would mean that you need to replace 3 microwaves of various sizes!
Microwave is too quick... I vote for a toaster oven. That's of course, after you've bricked it using whatever methods of corruption you find entertaining. You most likely need it rooted for anything fun.
The comment's sound like people voting on illegal snuff porn, except the snuff porn is replaced by an Iphone 5s OT: you should throw it to the toilet, shit on the phone and flush it.
Put the phone on top of a 500 ton block of C4 and detonate the C4 while standing 50 feet away so you can watch the phone die.
edited: jailbreak it and download virus, you can also connect it with a computer and delete the files (dont know if it works on newer ios)
go in a really sketchy website. like those " win a new iPhone" or "scan your computer now" type of ones. they always break these phones --- Post updated --- oh i know, attach it to a high voltage battery. that will kill it
