So i do long distance running and have a tomtom adventurer ,yet the battery is pathetic ,its meant to have 5gb of music to listen to, forget that it turns off after 30km. So ive researched on here and done the following complete reset,turned off heart monitor,turned of sleep,basically turned off all the functions and uses i brought it for. I ran 67 km ultra marathon yesterday thinking ive got this with my watch, guess what turned off after 52km. So what next i think a new watch from a different manufacture. Anyone out there have this problem

    You don't say how many hours it lasted for. 52km could be 5 hours or it could be 15. 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, the trails feature 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.

    What version of the firmware are you on? Later versions introduced battery issues and a rollback to 1.3.255 might help. You can request it here:

    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.
