Decide whether you need Fitbit’s sleek daily wellness coaching or Garmin’s sport-first accuracy—so you get the tracker that actually helps you hit your goals.
You juggle workouts and busy days—pick a tracker that keeps up. The Fitbit Charge 5 and Garmin Venu Sq 2 aim at different needs; this quick guide shows you how design, health features, battery life, software, and value differ so you can choose the wearable that matches your lifestyle and goals.
Daily Wellness
You get a focused, easy-to-wear tracker that emphasizes day-to-day health insights and sleep tracking while still offering built-in GPS. If you want accurate health sensors in a slim package and several days between charges, this is a strong, practical choice.
All-day Fitness
You get a polished mid-size smartwatch that leans into clear visuals, long battery life and broad fitness features. If you want an AMOLED display plus reliable multi-day tracking and sports profiles, this delivers strong value for active users.

Design, Display and Comfort: Wearability Matters
Overall look and profile
The Fitbit Charge 5 is a slim, rectangular fitness tracker with stainless-steel accents and a low-profile 1.04″ display that sits close to your wrist. It reads as a discreet tracker rather than a full smartwatch, which helps it disappear under sleeves.
The Garmin Venu Sq 2 is a 40mm square AMOLED smartwatch with a larger 1.41″ screen and a more pronounced case. It looks and feels like a full smartwatch — more presence on your wrist, clearer at a glance for notifications and maps.
Materials, straps and interchangeability
The Charge 5 uses stainless-steel case details and ships with S & L bands (silicone); bands are proprietary but comfortable and light. The device weighs about 29 g.
The Venu Sq 2 has a resin case and silicone strap (20 mm width), which makes it easier to swap in third‑party bands. It’s slightly heavier at ~38 g but still light for a 40mm smartwatch.
Water resistance and durability
Both are water resistant to 50 m, so you can swim and shower with either. The Charge 5’s metal accents feel a touch more premium; the Venu Sq 2 prioritises durability and sport-ready design.
Display, responsiveness and customization
The Charge 5’s 320×320 colour display is bright (up to 900 nits) and responsive to touch, but smaller text requires closer glances during workouts. The Venu Sq 2’s 400×400 AMOLED delivers larger, crisper text and an always‑on mode that’s easier to read mid-exercise. Venu Sq 2 also pairs touchscreen control with side buttons for reliable input during sweaty sessions.
Who it fits best and sleep comfort
If you have smaller wrists or want near‑invisible all‑day wear and lighter sleep tracking, choose the Charge 5. If you prefer a larger, easy-to-read screen, more band options and smartwatch presence, the Venu Sq 2 fits medium-to-larger wrists better — the trade-off is a slightly bulkier feel overnight.
Health and Fitness Tracking: Sensors, Accuracy and Features
Sensors and GPS
The Garmin Venu Sq 2 provides comprehensive optical heart rate, pulse oximeter (SpO2), accelerometer, and multi-GNSS GPS onboard for accurate pace and route tracking without your phone. The Fitbit Charge 5 focuses on continual HR, SpO2, skin temperature changes, EDA stress sensing and an ECG app — but in this comparison it relies on your phone for connected GPS, so outdoor pace/route accuracy depends on that connection.
Activity profiles and workout guidance
Garmin supplies 25+ built-in sports apps (running, cycling, HIIT, pool swim, golf) and on-device guided workouts and rep counting for gym sessions. Fitbit offers 20 exercise modes, automatic activity recognition and workout intensity maps — plus Premium workouts and deeper guided programs behind the subscription.
Recovery, stress and readiness
Fitbit’s headline feature is the Daily Readiness Score (Premium) that combines recent activity, HR variability and sleep to recommend rest vs. workouts. Fitbit Premium also unlocks guided programs, deeper sleep insights and more metrics. Garmin tracks Body Battery (energy), stress, respiration and offers longer-term trends — useful if you want passive, all‑day energy and stress context without subscribing.

Feature Comparison
Battery, Performance and Software Ecosystem
Real-world battery expectations
You’ll see the Charge 5 last around 5–7 days with typical all‑day heart‑rate, sleep and notifications; turning on Always‑On cuts that to a couple of days. The Venu Sq 2’s larger battery typically stretches to ~8–11 days in smartwatch mode; heavy GPS or Always‑On AMOLED use pulls that down to single‑digit days. Intensive GPS workouts, continuous music playback, and frequent notifications are the biggest drains on both devices.
Responsiveness, controls and performance
The Charge 5 is a speedy, single‑touch interface designed for quick glances and lightweight interactions. The Venu Sq 2 pairs a responsive AMOLED touchscreen with side buttons for more reliable control during workouts or sweaty conditions. In day‑to‑day use you’ll find both very responsive; heavy multisport sessions tax the Venu Sq 2 less thanks to its larger CPU and memory.
Syncing, apps and data dashboards
Updates, third‑party integrations and offline features
Firmware updates arrive regularly for both brands; Garmin pushes training and sensor improvements more often for watches, Fitbit focuses on health features and Premium content. The Venu Sq 2’s 4GB can support on‑device music storage on music variants and large activity caches — which speeds workouts but reduces battery. The Charge 5 offers music controls (no offline storage) and relies on a cleaner, more beginner‑friendly ecosystem.
Manage settings and workouts in either app easily: use Fitbit for straightforward health guidance and Garmin if you want configurable data fields, advanced workout creation and broader third‑party export.
Price, Value and Who Should Buy Which
Price context and included extras
The Fitbit Charge 5 sells for around £67 on Amazon and typically includes 6 months of Fitbit Premium—good value if you want guided programs, advanced sleep and readiness insights. The Garmin Venu Sq 2 sits near £177; you pay more for a larger AMOLED screen, longer battery (up to ~11 days), fuller sports app support and on‑device storage.
