**Brand:** Apple

The [Samsung Galaxy Watch 7](https://www.amazon.com/dp/B0D1YP3H4N?tag=shopsavvy00-20) has a slight edge in battery life, though both watches typically require daily charging.

### Official Battery Claims

| Watch | Standard Use | Extended Mode |
|-------|-------------|---------------|
| Galaxy Watch 7 (44mm) | Up to 40 hours | Power saving extends further |
| Galaxy Watch 7 (40mm) | Shorter (smaller battery) | Power saving available |
| Apple Watch Series 11 | Up to 24 hours | Up to 38 hours (Low Power Mode) |

### Real-World Battery Performance

**Galaxy Watch 7:**
Most users report 1.5 to 2 days with always-on display enabled. The 44mm model (425mAh battery) significantly outperforms the 40mm (300mAh battery).

**[Apple Watch Series 11](https://www.amazon.com/dp/B0FQF9ZX7P?tag=shopsavvy00-20):**
Improved from 18 hours (Series 10) to 24 hours. Most users charge daily, usually overnight or while showering. You can now reliably track sleep and make it through the next full day.

### Fast Charging Comparison

Both watches support fast charging:

- **Apple Watch Series 11**: 80% in ~30 minutes; 8 hours of use from 15-minute charge
- **Galaxy Watch 7**: ~80% in 30 minutes with 10W wireless charging

### What Drains Battery Faster

These factors affect both watches:

- Always-on display enabled
- Continuous heart rate monitoring
- GPS workout tracking
- Cellular connectivity active

### The Sleep Tracking Strategy

Both watches track sleep, requiring a charging strategy. The Galaxy Watch 7's longer battery makes this easier: charge 30 minutes before bed for sleep tracking plus the full next day.

Apple Watch users typically charge during morning routines. The 15-minute quick charge provides about 8 hours of use.

**Bottom line**: The Galaxy Watch 7 lasts slightly longer, but both watches need charging every 1-2 days.
