Battery Draining Fast
Ultrahuman Smart Ring
Severity: MinorWhat Does This Error Mean?
Ultrahuman Ring Air is rated for about 6 days per charge. If it is dying faster, SpO2 monitoring being on continuously or a firmware issue is the most likely cause. Disabling continuous SpO2 is the easiest way to recover battery life.
Affected Models
- Ultrahuman Ring Air
- Ultrahuman Ring Air Raw
- Ultrahuman Ring Air Aster
Common Causes
- Continuous SpO2 (blood oxygen) monitoring enabled
- Firmware bug causing higher than normal power consumption
- Ring is 1.5+ years old with natural battery degradation
- Frequent Bluetooth reconnections consuming radio power
- Very active lifestyle triggering more frequent sensor polling
How to Fix It
-
Disable continuous SpO2 monitoring in the Ultrahuman app if you do not need it.
SpO2 monitoring uses infrared LEDs running through the night, which is one of the largest battery consumers. Turning it off can recover 1–2 days of battery life.
-
Update the ring firmware to the latest version.
Firmware updates often include power management improvements. An unpatched firmware bug can significantly reduce battery life.
-
Keep Bluetooth stable on your phone — avoid toggling it repeatedly during the day.
Each Bluetooth reconnection forces the ring's radio module to broadcast at higher power to re-establish the link. Maintaining a stable connection saves ring battery.
-
Charge the ring every 5 days as a preventive routine rather than running it to zero.
Lithium batteries in small devices degrade faster when regularly deep-discharged. Charging on a 5-day cycle keeps the battery healthier for longer.
When to Call a Professional
If the ring is less than 1 year old and gets less than 3 days of battery with SpO2 off, contact Ultrahuman Support. Battery defects are covered under the 1-year warranty.
Frequently Asked Questions
How long should Ultrahuman Ring Air battery last?
Ultrahuman rates the Ring Air at approximately 6 days of battery life with all sensors at default settings. With SpO2 enabled continuously, expect closer to 4–5 days. Battery life naturally decreases slightly over 1–2 years of daily use.
Is there a low battery warning on Ultrahuman Ring Air?
Yes — the Ultrahuman app sends a notification when the ring battery drops below a threshold (typically 20%). You can also check battery level any time by opening the app and looking at the ring icon or the ring settings section.
