Hi, how long should the battery last on my watch. I charge it fully and within days, the watch dies as the battery is flat?

    You did not say what watch you had, but for the Spark lineup 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.

    However, if you search the forums you will find there is a known issue with rapid battery drain for many users with the recent updates, even though 1.7.64 was supposed to fix it. If you go to this post and ask the moderator to roll back your firmware version to 1.3.255 it should fix it.

    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.
