So, should you get a Forerunner 265 or an Instinct 2X Solar watch? We discuss these differences and other features of both watches below.

Display Specifications

Forerunner 265’s display is altogether at a different level when you compare it against the display of Instinct 2X Solar.

Forerunner 265 uses an AMOLED display. The AMOLED display technology helps in enabling the following benefits for Forerunner 265:

  • With an AMOLED display, the screen resolution is higher. The display screen and experience are brighter and afford a better readability experience too.
  • AMOLED display also helps in providing the Always-on-display mode or the AOD mode.

Due to the AMOLED display, the display sharpness of Forerunner 265 is high.

Instinct 2X Solar uses the normal MIP or Memory-in-pixel screen. So, it affords a lower display resolution.

Apart from the display technology, another important aspect of the Forerunner 265 is the display glass. Forerunner 265 uses a 3rd-generation Corning Gorilla Glass in the display. Instinct 2X Solar has a Power Glass in the display panel.

There are quite a few differences that you may want to make a note of:

Instinct 2X Solar is a solar watch. However, Instinct 2X Solar has very low device storage for any user activity. Instinct 2X lacks Wi-Fi connectivity. It does have higher water rating than Forerunner 265.


Forerunner 265 and Instinct 2X Solar support GPS, GLONASS, and Galileo networks.

But, the essential difference lies in the functionality of duel-frequency GPS or multi-band GPS.

Forerunner 265 has a multi-frequency positioning sensor. The multi-frequency positioning sensor helps in providing multi-band GPS capability.

With multi-band GPS, you can get GPS data from multiple satellites at any given point in time. Multi-band GPS helps in improving GPS reliability and accuracy.

The only downside to using multi-band GPS is the significant battery drain on the mode.

Multi-band GPS is only available in Forerunner 265. Instinct 2X Solar lacks it. The GPS accuracy and reliability is higher on multi-band GPS supported smartwatches.

SatIQ technology

Forerunner 265 uses multi-band GPS for better GPS accuracy. But, multi-band GPS causes significant battery drain.

To optimize the battery usage of the smartwatch, Garmin added a SatIQ technology sensor.

SatIQ manages multi-band GPS mode automatically.

When the GPS quality or connectivity is poor, SatIQ automatically turns on the multi-band GPS mode. When the GPS connectivity improves, SatIQ will turn off the multi-band GPS mode.

By automatically toggling on or off the multi-band GPS mode, SatIQ helps in conserving battery life in Forerunner 265.

Instinct 2X Solar does not have the SatIQ technology sensor.


The battery life of rugged smartwatches is always higher than other smartwatches. Understandably, the battery backup provided by Instinct 2X Solar is way higher than that of the Forerunner 265.

Let us evaluate different battery backups offered by Forerunner 265 and Instinct 2X Soalr below.

Watch modeForerunner 265 backupInstinct 2X Solar backup
Smartwatch modeUp to 13 daysUp to 40 days, unlimited with solar charging
GPS mode Up to 20 hoursUp to 60 hours; 145 hours with solar
GPS mode with musicUp to 7 hours
All-Systems GNSS mode + Multi-BandUp to 14 hoursMulti-band not available

SatIQ (AutoSelect) GNSS mode Up to 16 hoursSatIQ not available
SatIQ (AutoSelect) GNSS mode with musicUp to 6.5 hoursSatIQ not available

The battery of Instinct 2X Solar outlasts Forerunner 265 battery by quite a margin.

About Power Glass

Instinct 2X Solar uses Power Glass on the display screen.

Power Glass is a special type of glass. It has a layer of Photo voltaic cells or PV cells that are superimposed on the Corning Gorilla Glass. These PV cells help in converting solar energy into battery backup in the Instinct 2X Solar smartwatch.

About Solar Charging

Instinct 2X Solar is a solar watch that uses solar charging to build battery backup on the watch.

For solar charging to be effective, you will need to expose your Instinct 2X Solar watch to at least 3 hours of bright sunshine every day. The watch needs to be exposed to sunlight of 50000 lux or higher luminosity.

For people who spend at least 3 hours under bright sunshine, Instinct 2X Solar may offer a good value for its solar charging capability.

Final verdict

Instinct 2X is a rugged sports watch. I will buy it for the various activity profiles that come in-built into the Instinct 2X Solar watch. The solar charging in Instinct 2X Solar is also a meaningful feature.

For overall refinement and user experience, Forerunner 265 is my preferred watch for the following 3 reasons:

  • AMOLED display
  • Multi-band or dual-frequency GPS
  • Full music functionality
