Battery Life Keeps MIP Screens in Garmin Watches
Garmin says the power gap with OLED has not fully closed, so reflective displays remain in its lineup for now.

Would you choose a longer-lasting watch over a brighter screen?
Garmin says battery life is still the main reason its MIP (memory-in-pixel) displays remain in its smartwatch lineup, even as OLED efficiency improves. The Enduro 4, which uses a MIP display, offers up to 90 days of smartwatch-mode battery life with sufficient solar charging. This is an analysis of an existing product line, not a new launch.
Why it matters
The trade-off between MIP and OLED displays shows where wearable design is heading: power efficiency now shapes display choice more than brightness or color. Garmin's comments suggest the battery-life gap with MIP has not fully closed, which keeps reflective screens relevant for long-duration tracking.
The 90-day figure is a manufacturer specification for the Enduro 4 in smartwatch mode with sufficient solar charging, and the 3,000-nit peak brightness is the rated figure for the Fenix 9 Pro display. The source does not provide independent testing or a direct OLED comparison for either.
The players
Garmin
Garmin is a GPS and wearables maker whose smartwatch lineup includes the Enduro 4, Instinct 3 and Fenix 9 Pro, and it leads in solar-charged and MIP-display sports watches.
Brad Trenkle
Brad Trenkle is Garmin's chief operating officer, who said battery life remains the main reason MIP displays keep a place in the company's smartwatch lineup.
The details
A MIP display uses ambient light to stay visible, reflecting light off the screen instead of generating its own, which is why it draws little power. AMOLED screens, by contrast, produce their own light from organic diodes, which costs more energy. Garmin's solar technology collects energy through a ring surrounding the display rather than a layer over the screen, so the display itself keeps its clarity.
Timeline
Garmin recently launched the Enduro 4 with a MIP display; the exact launch date was not specified in the source.
The Tech Race
Garmin's Instinct 3 lets buyers choose between an AMOLED screen and a solar-powered MIP alternative, positioning the company against OLED-first wearables. The source frames the OLED-versus-MIP gap as not yet fully converged, which places Garmin's MIP lineup as a deliberate hedge in the broader race for longer battery life.
Buyers who prioritize multi-week battery life can consider MIP-display models like the Enduro 4, while those who want a brighter, more colorful screen can look at AMOLED options such as the Instinct 3. The source does not give pricing or availability dates for any OLED watch with solar charging, since Garmin has not announced one.
The takeaway
Watch for whether Garmin announces an OLED watch with solar charging, which would test whether harvesting sunlight can preserve display quality. The gap in battery life between MIP and OLED is the metric to track in future Garmin releases.
