Which is better for running and gym workouts?

The Venu 4, for most people. It has multi-band GPS, 80+ sports apps, Garmin Coach plans and daily suggested workouts. The Charge 6 covers the basics with GPS and heart rate at a much lower price.

Which lasts longer on a charge?

The Venu 4, at up to 12 days. The Charge 6 runs about 7 days, less with GPS workouts.

Is the Venu 4 worth the extra money?

Only if you want calls, music storage, a flashlight and deep training tools. At $450.00 at eBay as of November 5, 2026, it costs over five times the $84.99 Charge 6. If you just want steps, heart rate and sleep, the Charge 6 is enough.

Can I swim with either one?

The Charge 6 is rated 5 ATM, so it is fine for pools and showers. The Venu 4 is listed as water resistant but not waterproof, so keep it out of the pool.

Which is better for sleep tracking?

Both track sleep. The Venu 4 adds sleep scores, HRV status, naps and skin temperature, but its 45 mm steel case is heavier at night. The Charge 6 is lighter and easier to wear overnight.

Do both work with an iPhone?

Yes. Both support iOS and Android, though the Venu 4's call and voice features work best with Android.
