Techniques to increase battery life

I've got a Runner GPS watch. It works well but I'm looking for techniques to increase the battery life.

When I turn off all the features but the GPS (ie no HR etc) I get about 12-hours out of it which is pretty good, but I run ultras and so I'd like to get +15 hours at least.
Are there any tricks or techniques to increase the battery life by a few hours.

Can I...
  • charge it on the fly?
  • increase the sampling rate so it pings the GPS satellite less often
  • etc
Thanks guys

    There is no way to extend the battery life beyond 12 hours (and frankly I am surprised you get that much on an original Runner). You cannot charge it on the fly (the watch resets whenever it detects a change in power state) and you cannot change the sampling rate (simply not an option). This is unlikely to change considering TT has left the wearables market and is not producing any new devices and has recalled all inventory from the US (their largest market). We can safely assume at this point any updates will be limited to bug fixes (and even that may be limited - it has been over nine months since the last update broke connectivity for many users and introduced battery drain issues and that is still unresolved). I would not expect much more development and certainly not something major (particularly on the Runner as it has been out of production for years). You will need to buy another watch with longer battery life or use two watches switching out in the middle for longer events.

    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.

    Others have found that if your start with your device connected to a battery pack till that goes flat then disconnect and use the internal power supply it does not reset. Try experimenting with that scenario before you do your next 'ultra' ;)

    You can start with it connected but it is hit or miss. The trick is getting the cradle to not come loose the entire time (which will cause a reset), which is likely if it is in a pack. You also will not be able to wear it nor will you get HR. You could try taping it or something possibly, but I would practice it ahead of time. You're better off using multiple devices and joining the files together afterwards. You will still have two entries in MySports but you can upload the joined file to anywhere else you log your activities, like Strava.
