Apple Maps storage

Phone is iPhone X 64 GB on Verizon. iOS is 14.0.1.

While traveling in a situation with no access to WiFi for 10-11 days and using Apple Maps (CarPlay) for all navigation I noticed my phone was slowing and running warmer than normal. Charging also appeared to be happening slower than usual.

I tried to open the camera app to take a pic and got the message that iPhone storage was full and I could not take any more pics. I reviewed the storage being used by apps and Maps was using a whopping 32 GB and I could find no way to reduce that storage.

I reduced my total usage by deleting some pics. I also removed some apps that I was not regularly using. This resulted in my being able to take a few pics.

by the next day I received the iPhone storage full message again. I again checked storage used by apps and my Maps storage usage had grown to 37 GB. I tried removing Maps and rebooting my phone and even though Maps was no longer on my phone my storage was still using 37 GB for maps. I reinstalled maps and the condition remained.

That night I stayed in a place with decent WiFi and made sure that my phone completed a manual backup. In the morning I checked to insure that backup had completed, which it had. I checked storage and my Maps storage usage had reduced to less than 1 GB and my phone was showing 35 GB available.

Unfortunately, the warmer than usual, slow running, and slow charging condition remained. When I arrived home I forced another backup and reset my phone, using the backup just created. Things seem better so far, but this reset is only a couple of hours old, so I’m still reserving judgement.
