To enable: Swipe down on watch face Tap battery icon Enable Power saving
What it does:
- Disables Always-On Display
- Reduces brightness
- Limits background activity
- Disables vibration
- Maintains essential functions (calls, messages, time)
Power Saving Mode can double remaining battery life, reaching 80 hours on the 40mm and 95 hours on the 44mm.
Charging Time
The Galaxy Watch 5 charges faster than its predecessor.
- 0% to 100%: Approximately 80 minutes
- 0% to 50%: Approximately 35 minutes
- 0% to 80%: Approximately 60 minutes
Use Samsung's official wireless charging pad with a 5V/2A or higher power adapter for fastest charging.
Battery Health Over Time
Lithium-ion batteries naturally degrade with use.
- Year 1: 100% capacity
- Year 2: 95-98% capacity
- Year 3: 90-95% capacity
- Year 4: 85-90% capacity
To maintain battery health, avoid fully draining the battery, charge when reaching 20-30%, and don't leave the watch on the charger overnight regularly.
44mm for Extended Use
If battery life is a priority, choose the 44mm model. Its 410mAh battery provides 6-10 additional hours compared to the 40mm, making multi-day use practical with moderate settings.
