### ⭐ Battery issue
*by A***Y on 16 February 2026*

After 5 months of usage battery capacity decreased to ~ 1.5 day. Sometimes during the night ring hangs and does not provide sleep metrics at all. This issue also seems to be related to battery malfunction. Latest firmware and soft resets do not help.
