What actually makes an Android phone safe to keep for five years?
A long update promise is useful, but it does not automatically mean a phone will still be pleasant to own five years later. If you are choosing an Android phone specifically for five-year ownership, which factors deserve the most weight: software/security support, battery replacement availability, heat management, storage, repair cost, spare parts, chipset performance, build quality or brand service network? If you have kept an Android phone for four years or longer, please share the model and what aged first—battery, charging port, display, storage, performance, software support or something else. The goal is to build a practical long-term-buying checklist from real ownership.
