COROS PACE 4: problems, parts and running costs
Checked: 2026-10-17
Summary
The COROS PACE 4 is a 40 g AMOLED GPS running watch whose weak spots are the awkward digital dial, small notification text, optical heart-rate drift during intervals and cycling, and missing streaming music, payments and ANT+. It has no subscription and no consumables; the only running cost is charging electricity and an eventual battery replacement whose price is unknown. At $249 (COROS.com, October 2026) it is a good buy; the PACE 3 at $199 is the budget pick and the PACE Pro at $299–349 the upgrade path.
Common problems and fixes
- Digital dial with gloves — Runner’s World found it awkward when wearing gloves, causing accidental screen changes; the auto-lock workaround is imperfect. [5]
- No streaming music, payments or ANT+ — MP3 playback only from 4 GB storage that is shared with maps; no NFC; older cycling sensors and gym equipment will not pair. [3][4]
- Mineral glass scratches easily — more easily than Gorilla Glass or sapphire. [3]
- 4 GB storage caps maps — enough for a home region plus one travel destination. [3][4]
- Build-quality reports — some owners say the watch feels cheap, one reports a mushy start button, another reports the battery dying after about 7 months. [8][9]
- Old charger incompatible — the new USB-C adapter does not work with the PACE 3 charger, so existing COROS owners cannot reuse old cables. [3]
Parts and consumables
- USB-C charging adapter (new design; incompatible with the PACE 3 charger) — included in the box; no spare pricing found. [3]
- 22 mm quick-release band (silicone or nylon) — user-replaceable; no aftermarket pricing reported. [1][2]
- Battery — no replacement battery pricing or parts channel was published; one owner reported failure after about 7 months. [9]
Yearly running cost
Nothing to buy in a typical year. No subscription is required, and there are no consumables: the watch runs on its built-in battery, charged over USB-C, so the only yearly cost is charging electricity.
When it is a good buy
- At $249 (COROS.com, October 2026) — a strong position: it matches the Garmin Forerunner 70 on price while adding offline maps, dual-band GPS, a microphone and triathlon mode, and it beats the Garmin Forerunner 165 on GPS accuracy (dual-band vs. single-band) and battery life (41 h vs. 19 h). [3][5]
- $199 — at the PACE 3’s discount the older model becomes the budget pick. [3][4]
- $299–349 — the PACE Pro adds a larger screen, ECG and 32 GB storage; that is the upgrade path. [3][4]
- $449 — the PACE 4 Pro is the step up for titanium and sapphire. [3][4]
- Alternatives — the Suunto Run at $199 is the choice when the budget matters and dual-band GPS is not needed [7]; the Garmin Forerunner 165 is the pick when streaming music, NFC payments or ANT+ sensors matter, since the PACE 4 has none of those [3][4].
