I had two of these refurbished iPad with same issue.
Here is what I did to fix & also avoid it from happening again.
———-
This is how i fixed my ‘existing, problem:
- Put off Bluetooth from ‘Settings’ ONLY and not from the quick menu.
Go to settings—->Bluetooth —> off. Repeat this process twice. ON/OFF, ON/OFF. Do this process super ‘promptly’ as soon as the ipad turns on.
IF THE IPAD SHUTS DOWN BEFORE PERFORMING ABOVE MENTIONED ACTION. ? Then, Connect the iPad to charging and then turn iPad on. Then perform the settings->BLUETOOTH action. It won’t turn off when plugged in.
This is what I did to “avoid” it from happening again:
-Best & Permanent solution for me was — before plugging iPad into charging, ALWAYS turn the Bluetooth OFF.
-Not to put iPad into charging with ipad off. iPad should be ON while it is charging.
This is the only thing that worked for me.
Hope this might work. Worth a shot.
Thanks.
