Oura rings are worn 24/7 for sleep, readiness, and activity tracking, so the practical lifespan is often governed by battery health and cosmetic wear rather than catastrophic failure. Over time, batteries lose capacity, leading to shorter intervals between charges; charging docks and contact pads can also become finicky if kept dirty or exposed to moisture.
Because rings are compact, repairability is limited compared to larger electronics, and service often means replacement through support programs. Repair makes sense mainly when the charging dock is the issue or when a support option provides a cost-effective swap below the threshold.
Replacement becomes more sensible if the ring can't hold charge for a full day, if connectivity is unstable across devices, or if physical damage compromises water resistance. Also consider model generations: if newer rings offer materially improved sensors or comfort, replacement may provide better value than extending an aging battery.
