I still have not had any luck with settings' modifications. My 6s still dies out of nowhere, even though there is still supposedly a charge remaining on the device. I contacted Apple Support (or lack thereof) and after the mobile diagnostics checked out and all hardware components passed, the rep stated, "This is a really wired situation." Not exactly helpful in the slightest bit.

Here's everything I've tried:


    • Hard/Soft reset
    • Reinstall iOS from backup and from scratch
    • Reset Network settings (This did fix Bluetooth not detecting wireless headphones)
    • Turned off Bluetooth, Push settings, background apps, and location services
    • Disabled 'Optimized Battery Charging'
    • Enabled 'Low Power Mode' 24/7


None of this helped...
