Amazfit GTS 4 vs Samsung Galaxy Watch 7
The Verdict
Samsung Galaxy Watch 7 substantially outperforms the Amazfit GTS 4 despite costing $100 more. Samsung's 2000-nit Super AMOLED display with Sapphire Crystal glass is noticeably brighter and more durable than the GTS 4's standard AMOLED screen. Health tracking favors Samsung with ECG and skin temperature monitoring absent on Amazfit, plus full SpO2 and heart rate capabilities on both. Battery life represents the key trade-off: GTS 4 delivers impressive 8-day longevity versus Galaxy Watch 7's 30 hours with always-on display enabled. Processing power heavily favors Samsung's Exynos W1000 5-core chip with 2GB RAM, enabling faster app performance and smoother animations. Connectivity differences matter for some users, as Samsung includes NFC for payments while Amazfit omits it. Build quality leans Samsung with MIL-STD-810H durability certification and Armor Aluminum construction. Both share 5ATM water resistance. Amazfit targets users prioritizing marathon battery life and simplicity, while Samsung appeals to those wanting comprehensive health insights, snappier performance, and premium materials. For most users willing to charge every 1-2 days, Galaxy Watch 7's superior capabilities justify the premium.
