Garmin Forerunner 265: problems, parts and running costs

Checked: 2026-10-18

Summary

The Forerunner 265’s main complaint is the Elevate v4 optical heart-rate sensor, which tracks steady runs but suffers cadence lock and lag during intervals and strength work, so a chest strap is the usual fix. A January 2026 firmware update (27.09) also brought reports of heart-rate, step, sleep and battery faults for some users. There is no mandatory running cost, and at $350–400 it is excellent value against the $449.99 list.

Common problems and fixes

Optical heart rate unreliable in intervals and strength work — the Elevate v4 sensor suffers cadence lock and lags rapid changes; Garmin’s own support page acknowledges cadence lock and owners recommend a chest strap for those sessions. [3][8][9]
Firmware 27.09 tracking faults — the January 2026 update brought reports of unreliable heart-rate tracking, frozen step counts, missing sleep detection and faster battery drain; some users saw no problems and Garmin had not published a fix timeline as of late January 2026. [10][11]
No full topographic maps — navigation is breadcrumb trail and course following only; full colour maps stay on the 965 and 970. [7]
No speaker, microphone or voice assistant — the watch cannot take calls, and its app ecosystem is thinner than the Venu 3 or an Apple Watch. [3][4][6]
Display reflections and smudges — the Gorilla Glass 3 lens shows more reflections and fingerprints than the coating on the 965. [6]
Part number mismatch — the page product ID 010-02768-01 does not match Garmin’s published 010-02810-01 or 010-02810-00, so verify the number on the watch or its packaging; it may be a vendor-specific SKU. [1][12]

Parts and consumables

22 mm QuickFit-compatible silicone band — quick-release, so it is replaceable. [7]
Battery — built in and not user-replaceable; Garmin offers out-of-warranty replacement options rather than a user-serviceable battery. [7]

Yearly running cost

No mandatory running cost: Garmin Coach, Training Readiness and the core training metrics work without a subscription. Offline music playback needs a streaming service subscription, and storage is 8 GB, but that is optional. [2][3][7]

When it is a good buy

Garmin lists the watch at a $449.99 MSRP and it launched at $449 in March 2023; Consumer Reports listed it from $373.51 in July 2023 and a May 21, 2025 deal put it at $349.99. At $350–400 it is excellent value against the $449.99 list; at $450 and up, weigh the Forerunner 965 at $599, which adds full maps and longer battery, or the Forerunner 255 at $349–$399 if a MIP screen and more battery matter more than AMOLED.
