Recently I was given a pre owned iPhone 7 by a family member. The camera is great. The ability to place phone calls is great. I use the app to audit Trailers and Marketing Materials in movie theaters. ( Am I allowed to write the company name?)
Anywho I was busy clicking buttons and taking about 100 photos this week for 1.5 hours. The battery in the phone went from 95% down to 10% capacity in that time.
Anyone have experience with these audits? Is it the app that is draining my battery?
or
Do I need to purchase a new battery?
