6. Garmin Venu 4: Best Battery Life for Fitness
The Garmin Venu 4, launched in September 2025 from $549.99, trades some smartwatch apps for battery life measured in days. Garmin says it lasts up to 12 days in smartwatch mode. It includes an ECG app that can detect signs of atrial fibrillation, a Health Status feature that flags when overnight metrics move outside your normal range, lifestyle logging for habits such as caffeine and alcohol, and a built-in LED flashlight.
- Sizes: 41mm and 45mm.
- Best for: runners and anyone who hates daily charging. It works with both iPhone and Android.
How to Choose the Right Smartwatch
- Start with your phone. Apple Watches only work with iPhone. Pixel and Galaxy watches need Android. Garmin works with both.
- Decide how often you will charge. Most smartwatches need charging every one to two days, while Garmin and the Apple Watch Ultra 4 last much longer.
- Pick the health features you will actually use. ECG, readiness scores and sleep tracking are useful, but not every model has every feature.
- Consider LTE. A cellular model lets you call and stream without your phone, but costs more upfront and usually needs a monthly plan.
- Check the fit. Smaller cases are lighter and often more comfortable for sleep tracking.

A Note on Health Features
Smartwatch health alerts can prompt you to see a doctor, but they cannot diagnose conditions. Features such as ECG and irregular rhythm notifications have specific approvals and limitations that vary by country. If your watch flags a problem, or you feel unwell, contact a medical professional.
