In short

• Autonomy announced in connected mode: up to 11 days.
• In real use, count 5 to 9 days depending on settings and habits.
• Major levers: notifications, brightness of the AMOLED, SPO2 screen, number of hours of sport with GPS.

What is called "connected mode"

On the Garmin Venu 2, the connected mode corresponds to the daily use of a connected watch : Cardio sensor active wrist, permanent Bluetooth with smartphone, notifications, sleep monitoring and health widgets. In this context, theGarmin autonomy from 2 Remains comfortable, but depends closely on your routine and your settings.

Which really (or not) the battery

Notifications and vibrations

Rafales alerts light the screen and trigger the vibration. Sort the superfluous apps: you save battery duration on a daily basis without losing anything important.

AMOLED screen and brightness

The more the screen lights up and often, the more it consumes. Leaving the brightness in "car" and avoiding the display always on adds 1 to 2 days on a cycle ofConnected watch autonomy.

SPO2 and advanced metrics

The measurement of oxygenation during the night weighs moderately. Continuously, it costs more: limit it to sleep if you target balance.

GPS during sessions

GPS is the most energy -active position. Allow around 4 to 6 % battery per hour of racing with GPS. Three hour outings in the week thus consume 15 to 20 % of the total load.

Music and calls

Distribute music from the watch (Bluetooth headphones) or answer calls increases consumption during effort. Isolated, the impact is modest; Cumulated, it becomes visible.

Three realistic autonomy scenarios (connected mode)

• Light minimalist : Filtered notifications, Auto brightness, SPO2 at night, 3 GPS sessions of 45 min/week. Garmin autonomy from 2 : 7 to 9 days.
• Active daily : moderate notifications, 4 sessions of 1 hour with GPS, some musical listenings. Result: 5 to 7 days.
• Intensive visual : screen still on, SPO2 continuous, 5 sessions of 1 hour with GPS. Expect 4 to 5 days.

Simple gesture, direct impact

• Leave the brightness in "car" and cut the screen still on.
• Reserve the SPO2 to sleep.
• Clean notifications: keep the essentials.
• Group synchronizations to avoid screenwakes.
• During sport, lock the screen to limit unintentional ignitions.

Purchasing experience

• Check return and guarantee policy.
• Perform updates at the first start: they sometimes optimize theAutonomy in connected mode.
• Test comfort: bracelet, housing size, readability. Fewer manipulations, less ignition, better autonomy.

Summary

• Typical duration in connected mode: 5 to 9 days (up to 11 days announced).
• Key factors: Notifications, brightness/AOD, SPO2, Sport with GPS.
• Practical landmark: ~ 4 to 6 %/h during a GPS session.
• Objective: to settle finely to stick at your own pace, without giving up the useful.
