Apple Watch Series 8 (GPS + Cellular, 45mm) - Renewed Premium

Our review of the Apple Watch Series 8 (GPS + Cellular, 45mm) considers who benefits most from its health and connectivity features. The Renewed Premium Silver Aluminum model with M/L White Sport Band is aimed at iPhone users who want a large, always-on display and advanced sensors without paying full retail for a new unit. The single biggest reason to buy is its combination of the bright, 45mm Always-On Retina LTPO OLED screen and modern safety and health tools like temperature sensing, Blood Oxygen and ECG app, which make it a capable daily companion for fitness, safety, and on-wrist notifications.

Key Features

• Large Always-On Display: The 45mm, 484x396 pixel LTPO OLED screen delivers a clear, bright view up to 1000 nits for easy reading outdoors and an expansive 1143 sq mm area for complications and workout metrics.
• S8 SiP Performance: The 64-bit dual-core processor and PowerVR GPU provide smooth navigation through watchOS 9 and responsive app performance for daily use.
• Health and Safety Sensors: Temperature sensing, Blood Oxygen and ECG app combined with Fall Detection and Emergency Calling provide meaningful health monitoring and emergency support on the wrist.
• Cellular and Connectivity: GPS plus Cellular lets users stay connected without their phone, supported by Wi-Fi 2.4/5 GHz, Bluetooth 5.3, W3 wireless chip and U1 Ultra Wideband for precise proximity features.
• Battery and Storage: The watch includes 32GB of storage and a 308 mAh battery that handles daily activity tracking and notifications, with typical day-long usage expected.

Who It's For

The Series 8 is best for iPhone 8 or later owners who want a large-screen smartwatch with serious health and safety features and the option to use cellular service. It suits active users who value on-device sensors like ECG and Blood Oxygen alongside everyday convenience such as notifications and cellular calling.

People who should look elsewhere include non-iPhone users (an iPhone 8 or later with iOS 16 or later is required) and buyers who need multi-day battery life from a single charge; if you prioritize ultra-long battery endurance over sensors and a bright OLED display, a hybrid or fitness band may be a better fit.

Pros & Cons

Cons

• Battery capacity (308 mAh) is optimized for daily use but may require nightly charging for many users.
