Ring 4 needs replacement at exactly 1 year.
Replacement order confirmed and another data point for others.
I got my Oura ring using an AMEX card benefit credit and picked it up on October 7th last year. Its served well up until about the last software update, after which the time between charges dropped from a typical 5-6 days down to 2-3 days.
I searched threads and asked ChatGPT for solutions, which prompted me to use "Finn" the Oura ring AI chatbot. After 3 back and forth sessions, Finn repeatedly said everything was in normal range. Last night while showering at 9pm, I charged my Ring 4 up to 100%, and upon waking this morning my ring was down to 66%.
I gave Finn one more try and, lo and behold, Finn ran a diagnostic and found an issue. Replacement order on the way.
Question for those who had a replacement shipped recently, did anyone receive a newer Ring 5 or did you get a comparable Ring 4?
