Forerunner 165 vs Venu 4 45mm: Which Control and Call Setup Fits You?

Choose the Forerunner 165 if you want Garmin’s documented five-button layout, dedicated UP/DOWN scrolling and BACK lap/rest control, and do not need to speak through the watch. Choose the Venu 4 45 mm if you prefer its documented touchscreen swipes between activity data screens or want to take calls through the watch’s integrated speaker and microphone with a compatible phone. The manuals support feature fit, not an easier-control or accuracy winner.

The buying question

Do you prefer a five-button activity-control layout with dedicated scrolling and lap/rest actions, or a two-button Venu layout with touchscreen swipes between activity screens—and do you want calls spoken through the watch?

The Forerunner 165 manual describes five physical controls, dedicated UP/DOWN navigation and a BACK lap/rest or workout-stage action; the Venu 4 manual describes START/BACK buttons and touch swipes for activity data screens. For calls, the Forerunner routes speech through the paired phone, while Venu 4 documents calls through its integrated speaker and microphone with a compatible paired phone.

Quick verdict

Choose Garmin Venu 4 (45 mm, Slate with Black Silicone Band, 010-03014-00) if

  • You prefer using touchscreen swipes to move between activity data screens, with START and BACK buttons for the documented controls.
  • You want to place calls and speak through the Venu 4 or use a compatible phone assistant through its integrated mic/speaker.

When the recommendation changes
  • If your priority is touchscreen navigation during sport rather than dedicated physical scrolling buttons, the Venu 4 control path may fit better; this is a preference-based feature comparison, not a usability test.
  • If speaking through the watch is unimportant and you have no preference between the documented activity controls, the sources do not establish an overall performance or value winner.
  • Check the exact sport profiles and phone compatibility you need before buying; this comparison does not establish sensor or GPS accuracy differences.

The differences that matter

Sport Control Navigation Workflow

Garmin Forerunner 165 Running Smartwatch (43 mm, Black/Slate Gray, Non-Music, 010-02863-20)

The Forerunner 165 manual identifies five physical controls: LIGHT, UP, DOWN, START/STOP, and BACK. UP/DOWN scroll through data screens and settings; BACK can record a lap or rest during an activity or advance a workout stage. Its touchscreen can be disabled by activity profile and is unavailable during swimming.[1]

Garmin Venu 4 (45 mm, Slate with Black Silicone Band, 010-03014-00)

The Venu 4 manual identifies START and BACK buttons. During an activity, swiping up or down shows the next data screen; on-screen tips explain non-default button behavior. The manual also documents touchscreen selection and navigation.[2]

What this changes: Garmin documents a five-button layout with dedicated UP/DOWN scrolling and a BACK lap/rest or workout-stage action on Forerunner 165. For Venu 4 it documents START/BACK controls plus touchscreen swipes between activity data screens. If physical scrolling and a dedicated lap/rest control matter to your routine, compare these documented control paths; if you prefer touch gestures during activity, the Venu 4 manual describes that path. This does not establish that one is easier, safer, or more accurate.[1, 2]

The better fit depends on your priorities

Phone Voice Workflow

Garmin Forerunner 165 Running Smartwatch (43 mm, Black/Slate Gray, Non-Music, 010-02863-20)

With a connected phone, the Forerunner 165 shows incoming caller details and can accept or decline the call; Garmin says the user must speak through the connected phone.[1]

Garmin Venu 4 (45 mm, Slate with Black Silicone Band, 010-03014-00)

With a compatible phone connected over Bluetooth, the Venu 4 Phone app can place calls using its integrated speaker and microphone; the manual also documents phone-assistant commands through those components.[2]

What this changes: If you want to speak through your wrist or invoke a paired phone assistant audibly, Garmin documents that workflow for Venu 4. If call alerts and accepting or declining from the watch are enough and you will speak on the phone, the Forerunner 165 manual describes that simpler workflow. Phone compatibility and assistant behavior still depend on the paired phone.[1, 2]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Evaluate current offers against the control layout and phone-call workflow you will use. The sources do not establish that either watch is worth a particular price premium.

Check current prices, seller terms and availability when you are ready to buy. This comparison does not recommend buying now or waiting; price history was not assessed.

Limitations

  • No hands-on testing was performed; conclusions are limited to Garmin owner manuals and checked exact product identities.
  • The Venu 4 manual covers the 41 mm and 45 mm series; the selected product here is specifically the 45 mm part 010-03014-00.
  • The control comparison describes documented inputs and actions only; it does not establish that one interface is easier, safer or more reliable during exercise.
  • The Forerunner 165 manual says its touchscreen can be disabled by activity profile and is unavailable during swimming. This draft does not infer Venu 4 swimming touch behavior from manual silence.
  • Phone calling and assistant features require a compatible phone and Bluetooth pairing; support for every phone, carrier or app was not tested.
  • No comparative GPS, heart-rate, health-metric accuracy, battery-life, durability or long-term reliability testing was used.
  • Prices and availability can change; no long-term price history or timing recommendation is included.

Questions shoppers ask

How do the activity controls differ?

Garmin identifies five physical controls on Forerunner 165. Its UP and DOWN buttons scroll through data screens; BACK can record a lap or rest, or advance a workout stage. Garmin identifies START and BACK buttons on Venu 4 and documents touchscreen swipes up/down to view the next activity data screen. These are documented control options, not a test of which is easier to use.

Can I talk to someone through either watch?

On Forerunner 165, Garmin says the watch can show and accept or decline an incoming call, but you speak through the connected phone. The Venu 4 manual describes calls through its integrated speaker and microphone when paired over Bluetooth with a compatible phone.

Can I disable the Forerunner 165 touchscreen during an activity?

Garmin says the Forerunner 165 touchscreen can be customized for general use and each activity profile, and that it is unavailable during swim activities. This comparison does not infer Venu 4 swim-touch behavior from missing information.

Methodology and sources

Compared the actual control descriptions and activity-screen navigation in the two Garmin manuals, plus their phone-call steps. The five-versus-two physical button description is based on each overview; no claim about ease, accuracy, performance or usability testing is made.

Automation assisted with research organization and drafting. Product behavior claims use the cited Garmin documentation; no hands-on testing was performed.
