On Edge 130 it does not refresh to the actual value (that from the service menu) it displays the useless battery info as the builtin graphic one ... I think there is a problem with the device itself.

Yeah that's likely the case, there's nothing device specific in this app, it's really just displaying and logging the value passed to the datafield. Maybe open a thread on the Garmin forum about it.

Works amazing. Surprised Garmin doesn’t come with it. One question though. My watch tells me I have 100% when the data field says I have 97% does that mean the data field is saying I have a max capacity of 97%?

Hey hi thanks! Yeah I also think it should be a standard feature, hope Garmin will pick it up eventually. :-) About the battery level close to 100% with the datafield reporting less, the API documentation mention that the watch keeps displaying 100% even though the charger has been disabled and the battery may have discharged slightly, the datafield is the actual level. See https://developer.garmin.com/connect-iq/api-docs/Toybox/System/Stats.html#battery-var, nothing to worry about.

Absolutely a wonderful data field! The Connect App graph is really a big help in seeing my 955 Solar's battery drain during a workout. Two questions: 1) Do you know if the 955 naively writes the battery drain information to the FIT file and if so where might I find it in the file? 2) When I look in the FIT files after having installed your data field, the battery percentage appears to move around from Field23 to Field26. Is this normal or might this be a function of converting the FIT file to a CSV format? Thank you for creating this great data field -- it is exactly what I needed. Chris

Hey thanks! Yeah I think most Garmin devices writes the battery drain in the fit file (my old 230 had it as well), but it's not in the "record" message (the one with the gps data, speed etc...), it's on a separate "battery" record that gets recorded every 5 minutes. I use https://github.com/mrihtar/Garmin-FIT to decode fit files, it should show up with that. As for the field number, developer data gets appended at the end of the standard record after the standard ones. I never used a CSV decoder but I would not be surprised if the field move around depending on what else is configured in the activity (extra sensors etc). Does the converter give you a field header to map the field to something known? Either way I would suggest using a fit decoder library directly instead of going through the CSV.

But where do i see the chart? Sry new to garmin

Hi! You need to add it to one of the screen for the activity you are using, and then you can find the graph next to the other graphs (speed/pace, heart rate, elevation...) in the Connect app or website.

Spot On and exactly what I was looking for. Simple & functional. Will be a great analytical tool both on the run and in Garmin Connect

Fantastic simple app, does what it says on the label. Great for tracking how much battery is used by your devices after the fact. Would be nice if there was a feature to record sensor battery life as well.

Developer Reply

Hey thanks! The problem with sensors is that there's no generic way of getting a reliable battery level indication. For BLE, you just can't with the current API, for ANT+ you may be able to get either a battery voltage, operating time or a status level. The voltage and operating time are sensor specific (if they are even reported), and the status is fairly coarse, just new/good/ok/low/critical, so not too interesting to log. The status is pretty much for the "low sensor battery" warning, that I think all device already implement.

Works well on several of my GPSr - Just wish output to GPX files also! Will give 5-star when it does!

Developer Reply

Hey Andy, sadly that is not possible with the current APIs, the only supported way of recording extra data is through FIT developer field extensions. Most CIQ devices don't even record GPX files natively, and when you export one from Connect the conversion from the FIT file happens server side, so I don't see that happening in the future. I'm not even aware of an existing tool that does that so if you need that you'll have write your own. If it helps, the library I use for inspecting FIT files is this one: https://github.com/mrihtar/Garmin-FIT.git, and it's good enough to extract the data, including developer extensions.
