Unable to accept new iCloud Terms and Conditions

New iCloud Terms and Conditions To use iCloud on this iPhone You must accept the new iCloud Terms and Conditions and enter your iPhone passcode.

I got this joke. But after clicking next, “I can’t complete the action.” Do I really need to update iOS? I don’t want to update it, it was that after the update the battery ran out faster. even at night when the phone was not touched. I don't want this story to repeat itself, is Apple FORCING me to update? because my iCloud doesn't work without confirming this joke
