I can’t even find my MagSafe charger listed. I’m wondering if I got screwed and purchased a counterfeit Apple MagSafe charger. I got it at Walmart though so I wouldn’t think so but heck you never know! I’m gonna keep trying.
It should be under Settings > General > About > in the third column, where WiFi and Bluetooth and Modem Firmware is listed.
Make sure the MagSafe is plugged into the charger and connected to your iPhone as well.
I have to MagSafes and both haven’t been updated.
