Health and Fitness Tracking Compared

All Apple Watches excel at health monitoring, but capabilities vary by model:

Battery Life and Charging

Battery performance varies significantly across models:

Apple Watch Ultra 2

• Normal use: 36 hours
• Low Power Mode: 72 hours
• GPS tracking: 12 hours continuous

Apple Watch Series 9

• Normal use: 18 hours
• Low Power Mode: 36 hours
• GPS tracking: 6 hours continuous

Apple Watch SE (2025)

• Normal use: 18 hours
• No Low Power Mode option
• GPS tracking: 5 hours continuous

All models support fast charging (0-80% in about 45 minutes) using the included magnetic charging cable.

GPS vs Cellular Models

Each Apple Watch model is available in GPS-only or GPS+Cellular configurations:

• Cellular adds $100 to the purchase price
• Requires compatible iPhone and carrier plan ($10-$15/month)
• Enables calls, texts, and streaming without iPhone nearby
• Uses same number as your iPhone (number sharing)

For most users, GPS-only is sufficient unless you regularly exercise without your phone. The Ultra 2's cellular performance is notably better with dual-SIM support for international travelers.

Apple Watch sizing considerations:

Ultra 2

• Only available in 49mm
• Best for wrists 165mm+ circumference
• Considerably larger than other models

Series 9

SE (2025)

• 40mm or 44mm options
• Similar sizing to Series 9

Visit an Apple Store or authorized retailer to try different sizes before purchasing.
