Hi all. Chuffed with my new Runner 3. Just the GPS version.

Went for a trail guided MTB ride in the mountains today. 4 hours long, battery decreased from 95% to about 33%. That seems like quite a drain... Is it possibly because I forgot to switch off the bike and heart sensor? (I don't use that equipment).

    If these sensors were on it will impact battery life as it is looking for them the whole time. Battery life is rated for around 5 hours for GPS/HR/Music, 9 for GPS/HR, 11 for GPS only, 2 weeks for watch only (that includes pause time as the sensors are still on - so if during a 2 hour activity you had 30 minutes of pause it was 2:30 of battery life, not just the 2 hours it was recording for). Those of course are estimates and best case scenario and are impacted by usage (using backlight, switching screens, etc.) and environmental conditions (overcast skies, tree cover, tall buildings, etc.). If you have night mode or the backlight on that is going to impact it greatly. I have found that they are pretty accurate estimates and my usage and testing has pretty well matched them. Bear in mind that the battery gauge is a rough estimate at best and I have gone many hours when it indicates that it was almost empty.

    I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.

    Hi, it's normal, I use it every day and GPS every afternoon and I have to recharge it every two days or so.
