iPhone 6 plus - device fully loaded?

[kaitlyn]

I've done a few flights with my 6 plus and Mavic 2, including a full day of flying yesterday. Today I was flying for maybe 8-10 minutes when suddenly my phone crashed/restarted. Comes back and says device could is fully loaded. Shortly after it crashes again.

Any idea what might be causing this? How I can prevent it? Why it didn't happen at all before but now twice?

I just realized I updated to iOS 12 last night... Surely that could be related? Ugh!

I haven’t updated to iOS 12 yet, but I got the same message last week on my iPhone 6s. Emptied my deleted photos folder and haven’t seen it again. I was showing 5 gb still available and cache to phone was turned off. Hope it’s not an issue with iOS 12.
