In my own experience, battery optimization is worse (or the benefits are out-weighted by) than higher battery capacity. Reason being that after 1 year when your battery has degraded, and in combination that we don't take much care of ours phones (apps installed, services running...) then the phone starts lasting less than 1 day, which for me is not acceptable. I have a pixel phone that lasted 32 hours of battery. After more than one year it now lasts 17 hours. I'm sure that part of it I could fix by identifying some battery-hungry apps or formatting my phone, but most of it is just due to battery degradation as can be seen in battery health. Even though I use adaptive charging (at night it charges slowly until my alarm hour)

  The background app using extensive battery is more a problem on Android, so may be unrelated to this article

  EVERYTHING fails and dies (entropy) so it's really a matter of choosing how you "live the life and deal the the inevitability death" (of the battery, not your own). Having a choice with more openness of controls is probably the best customer feature.

  That seems like a massive amount of battery degradation if that is the cause. I would not expect battery degradation to amount to more than 10-20% in a year based on my experience.

When compared to Samsung's flagship it's pretty impressive. The iPhone 13 Pro Max is getting 21.68 hours of web browsing out of a 4352 mAh battery vs. the Samsung Galaxy S21 Ultra (Qualcomm 888 variant) getting 15.91 hours of web browsing out a 5000 mAh battery. When you consider the SPEC 2017 performance metrics published earlier (A15 performance core - 7.28 integer & 10.15 floating point vs. Qualcomm 888 X1 core - 4.48 integer & 6.28 floating point) it's more impressive. https://www.anandtech.com/show/16983/the-apple-a15-soc-performance-review-faster-more-efficient/2 https://www.anandtech.com/show/16983/the-apple-a15-soc-perfo...
