Chosen Solution

I was texting my friend, and a notification popped up from her, so I clicked it, but it didn’t open the messaging app, so locked the screen. I tried pressing the home button to turn it back on, but the screen stayed black. I was going to try resetting it, but the home button doesn’t work, and I don’t know when the last time my phone was backed up. Also, when i plug my phone into my laptop to connect to iTunes, it doesn’t acts as if it doesn’t know it is plugged in. I have an upgrade coming up on July 14th, should I try to fix it, or just hold out? Let me know if you have a solution to my VERY strange problem. Update (07/08/2016) I went to this website and typed in my information. It told me my battery percentage, which was 4%. I clicked on “Lost Mode” and typed a test message, which wound up lighting up the background screen and nothing else. I decided from there, that I should let my battery die all the way down, so I clicked “Play Sound” which was very annoying, but killed my battery VERY fast. From there, my phone died all the way down, so I plugged it in to charge, and it is working again! Thank you +Ellis O’Brien for taking me to this site! Very helpful!

If you have any tools and are willing to open up your phone, you could try removing the battery and reinserting in after 10 minutes or so (act as a reset). Follow iFixit’s battery replacement guide to remove the battery
