The biggest reason for you to buy a Forerunner 955 over a Forerunner 945 is the improved GPS performance.

Forerunner 955 has a multi-frequency positioning sensor. This sensor helps in providing multi-band GPS support on the Forerunner 955 watch.

With multi-band GPS, you can get GPS data from multiple satellites of a satellite system at a given point of time. Multi-band GPS is very useful in remote areas or in areas with tall structures.

Apart from multi-band GPS, the SatIQ technology also helps in improving the performance of your Forerunner 955 watch. SatIQ allows the watch to automatically toggle between multi-band GPS or the standard GPS mode.

SatIQ technology helps in the judicious use of the battery and improves GPS performance without draining the battery.

Multi-band GPS and SatIQ technology are the biggest benefits of the Forerunner 955 in comparison with Forerunner 945.


The difference in battery backup offered by Forerunner 955 and 945 is marginal. On the GPS modes, both provide almost equivalent battery backup.
