Garmin's 2026 entry Forerunner puts a 1.2-inch AMOLED touchscreen and five buttons on a 40 g watch, and Garmin says it carries over training readiness, training status, wrist running power and running dynamics from its pricier Forerunners. It is the longest-lasting of the two May 2026 models at 13 days per charge. Garmin Pay, music storage, a barometric altimeter and a compass are all reserved for the Forerunner 170.

Weight

40 g

Garmin spec: 'Weight: 40 g' (Garmin does not say whether the band is included)

Best for: A first-time runner who wants adaptive coaching and recovery metrics without paying for payments or music

Battery: the claim and the other two figures

Claimed (smartwatch mode): 13 days
With always-on display: 5 days
GPS workout: 23 h

Headline: Garmin: 'Smartwatch mode: Up to 13 days'.
Always-on: Garmin: '(5 days display always-on)'.
GPS: Garmin: 'GPS-Only GNSS mode: Up to 23 hours'; 'All-Systems GNSS mode: Up to 16 hours'.
Garmin: 'Battery Saver Smartwatch mode: Up to 28 days'; no multi-band mode on this model

The ring’s outer track is the headline claim; the inner two are the always-on and GPS figures as a share of it. An empty track means Garmin does not publish that figure. Why the figures differ

Phones, paid tier and updates

iPhone:: Yes, with limits.
Android:: Yes.; Garmin's spec table marks text replies and reject-call-with-text as Android only; iPhone owners get notifications but cannot reply from the watch
Paid tier:: Garmin Connect+, $69.99/year.; No watch feature requires it: Garmin's chart keeps activity details, health stats, performance metrics, Garmin Coach plans, courses and LiveTrack in the free app. Connect+ adds Active Intelligence AI insights, nutrition logging, a desktop performance dashboard, live activity on the phone, 3D maps and offline Garmin Trails downloads; Watch plus two years of Garmin Connect+: ~$390.
Software updates:: Garmin does not publish a guaranteed number of update years for this model.

Cleared health features

Garmin cites no regulator clearance for a health feature on this model. Its heart-rate, sleep and blood-oxygen readings are wellness features.

A clearance says what a feature is allowed to claim, not that it replaces a doctor. Cleared versus wellness features

What the extra money buys: The cheapest Garmin running here. 4 pricier siblings in the same line: Garmin Forerunner 170, Garmin Forerunner 265, Garmin Forerunner 570.

Garmin Run Coach plans, including new run/walk plans

Where the specs put it ahead

Gets the same training-readiness and running-power metrics as Forerunners that cost far more
Three more days per charge than the Forerunner 170 in smartwatch mode
Always-on mode still lasts five days, so the bright screen rarely needs to be turned off
Free Garmin Coach plans with run/walk sessions cover couch-to-5K training without a subscription

What it gives up

No Garmin Pay, music storage, barometric altimeter or compass; the Forerunner 170 adds those
No multi-band GPS, so tall buildings and tree cover can throw off pace and distance
Text replies from the watch work only with Android phones
No maps, only breadcrumb courses
