Which Fitbit Should You Buy? Charge 6 vs Versa 4 Compared

Fitbit's current lineup splits cleanly: the Charge 6 is a focused fitness tracker with GPS, while the Versa 4 is a full smartwatch with Google app integration. Your choice depends on whether you want a lean tracker or a wrist computer.

Why Fitbit?

Fitbit, acquired by Google in 2021, has spent 14 years refining wearable fitness tracking. They specialise in heart-rate monitoring, sleep analysis, and step counting—the core metrics that matter for daily health. Unlike pure smartwatches (Apple Watch, Garmin), Fitbit prioritises battery life over features: Charge 6 runs 7 days, Versa 4 runs 6 days. Their app ecosystem is built for simplicity rather than complexity, which appeals to people who want data without overwhelm. Google's ownership means tighter integration with Gmail, Calendar, and Google Maps—useful if you're already in the Google ecosystem, but less relevant if you're Apple-heavy.

Top Picks

Google Fitbit Charge 6 Fitness Tracker, Obsidian

Price: £129.95

Best for runners and commuters who need GPS without smartwatch bloat. The 1.4-inch AMOLED display shows maps in real time, heart rate sits between 40–220 bpm (accurate for most users), and the band system accepts third-party straps. 7-day battery means you charge weekly, not daily. Standout: Google Maps integration lets you see turn-by-turn directions on your wrist during runs.

Fitbit Versa 4 Copper Rose Aluminum, Pink Sand Strap

Price: £149.95

Best for those wanting a smartwatch that doubles as a fitness tracker. Larger 1.58-inch AMOLED screen, Google app integration (Gmail, Maps, Calendar), and faster performance than Charge 6. Built-in music storage (40 hours) lets you run without your phone. 6-day battery is shorter than Charge 6 but still better than most smartwatches. Standout: Google Assistant voice control and full app ecosystem without sacrificing 6+ days of battery life.

Fitbit Charge 6 Fitness Tracker (Manufacturer Refurbished)

Price: £129.99

Best for budget-conscious buyers who don't mind refurbished stock. Functionally identical to the new Charge 6 with GPS, 7-day battery, and AMOLED display. Comes with both S and L bands included. Standout: same performance as the new version at refurbished prices, with a safety net if you're hesitant about commitment.

Quick Comparison

| Product | Price | Best For | Standout Feature | |---------|-------|----------|------------------| | Charge 6 | £129.95 | GPS tracking, daily fitness | Turn-by-turn maps on wrist | | Versa 4 | £149.95 | Smartwatch + fitness hybrid | Google Assistant, music storage | | Charge 6 Refurbished | £129.99 | Budget buyers | Both S and L bands included |

What to Look For

• Battery life vs features trade-off: Charge 6 gives 7 days; Versa 4 gives 6. If you travel frequently or dislike charging, Charge 6 wins. If you want app notifications and voice control, 6 days is acceptable.
• Display size matters: Charge 6's 1.4-inch screen is narrow (good for small wrists); Versa 4's 1.58 inches is noticeably larger and easier to read. Measure your wrist circumference—Charge 6 suits sub-170mm wrists comfortably.
• GPS accuracy: Both use standard GPS, but Charge 6's integration with Google Maps gives real-time turn-by-turn routing. Versa 4 has GPS but no native map display—it logs your route but won't show directions on-wrist.
• Heart rate monitoring range: Both track 40–220 bpm. If you're an endurance athlete pushing above 180 bpm regularly, these are reliable. Casual fitness users (120–160 bpm zones) see excellent accuracy from both.

The Bottom Line

Buy the Charge 6 at £129.95 if you run outdoors, cycle, or want your tracker to last a full week. It's the leaner choice—better battery, GPS maps, lighter on features. Buy the Versa 4 at £149.95 if you want notifications, voice control, and a bigger screen; the 1-day battery sacrifice is worth it for smartwatch functionality. The refurbished Charge 6 is your safety valve: same performance, same price, both bands included—no downside if you're new to Fitbit.

Frequently Asked Questions

Is Fitbit good value for money?

Yes. At £129–£149, both models undercut Apple Watch (£249+) and offer longer battery life. You're paying for fitness tracking accuracy and simplicity, not an app ecosystem. If you only care about step counts and heart rate, Fitbit delivers that better than more expensive alternatives.

Can I use Fitbit with an iPhone?

Yes. Fitbit works with iOS 14+ and syncs all data (steps, heart rate, sleep) to the Fitbit app. However, you'll miss Google app integration (Maps, Gmail, Calendar notifications)—that's Android-only. If you're on iPhone, you get the fitness tracking but fewer smartwatch features.

How accurate is Fitbit GPS?

Very accurate for running and cycling routes. Tests show ±3–5% margin of error over 5km runs, which is standard for consumer GPS watches. For step counts and heart rate, Fitbit ranks in the top tier—better than Garmin for casual users, comparable to Apple Watch. Sleep tracking is less precise (misses light sleep sometimes) but good enough for trend spotting.

Should I buy refurbished or new Fitbit?

Refurbished is safe. The £0.04 price difference between new and refurbished Charge 6 is negligible—buy refurbished only if stock is lower on new. Refurbished units come with the same 1-year warranty, and Fitbit's failure rates are low (≈2% in first year). The real benefit: you get both S and L bands included with refurbished, so it's actually better value.
