Hello! What can be the problem of an iPhone 7, new (was bought a month ago), that had a very good battery life, if the battery life suddenly got really worse? We're talking about 100% to 32% in 5-6 hours, with moderated use. Before this started it had a very good battery life - lasting for an entire day of use, with one charging needed overnight or something like that. Now, it's just weird. No change in the use of the iPhone itself. Obviously something here is odd. What seems to be the problem?
