I was about to, but I have some issues with battery life and charger plug, so it would be cheaper to buy a lower end iPhone (like the 12 mini) - so I am in a slight dilemma now.

Most likely if this phones battery gets any worse, I will upgrade to the new iPhone 12 max (or current flag ship) and hope it will last years to come. My iPhone is I think now 5 years old, where the average phone life seems to be 2-3 years, so I am quite happy with the quality and don't mind the upgrade, when it is necessary

edit: For reference, replacing the glass is 200€
