3 Garmin settings you should change today

Nothing is broken on your watch. These three settings are just working exactly as designed — and what they're designed to do costs you battery for very little in return.

1. Gesture wake

Every time you turn your wrist, the screen lights up. Sounds convenient, until you count how often it actually fires: in the car, cooking, typing, rolling over in bed. That's hundreds of wake-ups a day, and you look at almost none of them.

Turn it off, and tap the screen when you actually want to check it. On a touchscreen model that's one tap; on a button watch, press any button. You lose nothing you were using and get a meaningful chunk of battery back, especially on AMOLED models where lighting the display is the single biggest power draw.

2. Pulse Ox

Blood oxygen is the most power-hungry sensor on the watch — the LED has to shine straight through your skin, which draws far more than a simple heart rate reading. And unless you're training at altitude, monitoring a respiratory condition, or specifically curious about your sleep breathing, it's not a number you check often.

Turn off all-day Pulse Ox (Garmin Connect → your device → Health Stats or Sensors) and battery life improves noticeably, particularly overnight. If you only care about it during sleep, most watches let you keep sleep-only tracking and drop the all-day mode — a good middle ground.

3. GPS mode

Most watches default to All-Systems or Multi-Band GNSS. That mode genuinely earns its keep between skyscrapers or under heavy tree cover, where extra satellite frequencies fight through reflection and signal loss. On your normal loop around the neighbourhood, it's doing nothing you'd notice.

In your activity settings, switch GPS mode to plain GPS-only for everyday runs and rides. Accuracy stays more than good enough for pace, distance and route — and GPS is one of the single biggest battery drains during any tracked activity, so this is the change with the biggest payoff of the three.

Save multi-band for when it matters

Don't turn it off permanently — switch it back on for a genuinely tricky environment: a dense urban core, deep tree cover, or a race where you actually need every metre of accuracy. The rest of the time, GPS-only is the better trade.

Not every Garmin offers all three of these settings — Pulse Ox and multi-band both depend on the model. Check what your watch supports, or what a model you're considering supports, here:
