For those who are deciding between a new iPhone and battery replacement

I got my iPhone 11’s battery replaced one year ago, and its health is at 91% already. By contrast, the original battery took 4 whole years to come down to 78% health - at which point I went for the replacement. Not sure if it’s down to the updates (I’m on iOS 18) or because the apps have become more power hungry in these 5 years. I thought I should share this observation to help someone decide whether the replacement cost is worth it.
