### ⭐ Only 90 days warranty! Check ASAP your device.
*by D***L on 9 February 2026*

Ring 4, ~3 months old, iPhone 16. Disconnects at least every 1–2 hours; when it happens, the app/phone can’t find the ring until I place it on the charger (charger LED turns on immediately). Completed soft reset + factory reset + full re-pair (forgot device in iPhone Bluetooth) — issue persists. Battery now drains within a single day. Please check diagnostics and advise warranty replacement if hardware/battery issue is suspected.
