Have you checked your battery health recently? Apple only considers that a battery requires replacement if it cannot hold, at least, an 80% charge after 500 full recharging cycles.


Also, for a while after updating an iPhone, it may go through a series of activities before it "settles down" to a more "normal" battery consumption rate ... not just background app updates.

I have checked all of my settings, apps running in the background, network reset settings everything. My battery goes from 100 down to 95 very quickly. Let's use reasonable deduction. Before the update, my phone drain was minimal. After the update, my phone now drains fast. Reasonable deduction says that there's something in the update that Apple needs to address immediately. As I am not spending a thousand dollars on a new phone.
