How to prevent photo uploads to iCloud from pausing?

(Steve Jobs would never have stood for it)

For what? The internet being a fickle thing at times?

There are likely connectivity issues that cause this.

Is there any way to never pause during uploads?

Reality is, if you did not pause the upload, it continues until it can't. There is no "keep going" setting.

Updating the iCloud Photo Library is not just a big upwards dump. There are data integrity checks ongoing throughout.

How many photos? Videos? How long has the upload been going on? What kind of wifi connection?

There are many variables to consider.

Answered.

The question is simple: is there a way to cause an iPhone to continuously upload photos to iCloud without pausing?

That is the default setting. Unless you pause the upload, your phone is uploading.

There is no /keep_uploading_without_pausing switch.

You do not have control of the entire path to iCloud.

What about the other questions I asked in an effort to help you?

Nothing wrong with the internet here.
