Hi guys, my iPhone 5s (ios 10.0.2) has been shutting down completely randomly (usually when i'm not using it). After it shuts down, I am no longer able to turn it back on (I tried pressing the home+power button). The only way i can get it to work is to plug it into my computer, open itunes and restore the entire thing (itunes tells me that it has detected a phone in recovery mode). After restoring it, it still shuts down. Any ideas? Thanks. Sorry if this has been asked!!
