Battery drain iphone 6s

Here is what is happening...the photo app is stuck in "curating" optimization mode. It continues this in the background so if you have a lot of photo's it will eat your battery.

I have a 6S that is in perfect condition, never dropped or exposed to moisture and a new battery was installed by Apple. Apple said the battery drain was a "hardware issue". Nope, it was the software.

After I received my new phone (iPhone 11) I deleted everything on my 6S. Since the pic's were gone and icloud was not syncing photo's, guess what...my 6S has been on for several days and the battery percentage is still the same. 2 days ago it was 74%, this morning it was 74%.

Unhappy that Apple could not figure this out and I was compelled to buy a new phone.
