Apple Watch Series 9 Review
Verdict: If you use an iPhone and want the fastest, most polished everyday smartwatch with strong health tracking and plenty of storage, buy the Apple Watch Series 9; skip it if you need multi‑day battery life or rugged specialist features.
The quick answer
You get flagship speed (S9 SiP), a brighter always‑on screen and 64GB of onboard storage for playlists — all for £219.99 (renewed aluminium). At a score of 8.4, it’s the best daily smartwatch match for iPhone owners who want responsiveness and accurate health data, but don’t expect multi‑day battery life.
What we tested
A renewed 45mm aluminium GPS model (midnight) with battery health >80%; used for 30 days across commutes, outdoor runs, gym sessions and overnight sleep tracking paired to an iPhone.
What it does well
Processor: noticeably snappy The S9 SiP with a 4‑core neural engine keeps animations smooth, makes on‑device Siri faster and powers the Double Tap gesture so simple wrist taps feel immediate during workouts.
Storage: room for offline music 64GB of internal storage means you can store playlists and podcasts on the watch itself — no juggling space when you want phone‑free runs.
Display: bright and readable outdoors The Always‑On Retina LTPO OLED (45mm ≈ 1.9") is brighter than Series 8 and stays legible under direct sunlight, so glance information is actually useful on daytime runs or commutes.
Health sensors: full everyday coverage Optical heart rate, ECG, SpO2 and temperature sensing plus fall detection deliver the same broad health tracking Apple pushes across watchOS — reliable readings for workout, sleep and general monitoring.
Integration: seamless with iPhone Tight iOS pairing, faster Wake and on‑device features mean notifications, Apple Fitness integration and Siri work with less lag than most Wear OS watches paired to iPhones.
Where it falls short
Battery life: you’ll charge nightly Rated at around 18 hours in typical use; real‑world testing matches Apple’s claim — you’ll likely need to charge every night. If you want multi‑day endurance, this will frustrate you.
Independence: GPS‑only limits phone‑free use The GPS model lacks cellular, so you can’t fully leave your iPhone behind for calls or streaming — important if you want true phone‑free freedom on long outings.
Rugged and specialist activities Aluminium renewed cases are light and comfortable but not built for extreme outdoor use. If you need hardcore GPS accuracy, extra battery or dive‑grade durability, the Ultra range or dedicated Garmin models are better fits.
How it compares
The nearest rival is the Samsung Galaxy Watch 6. Choose the Series 9 if you own an iPhone and want the tightest software integration, faster on‑wrist interactions and more local storage; pick the Galaxy Watch 6 if you’re on Android or want a similar feature set without being locked into Apple’s ecosystem.
