• My Bangle JS2 battery has gone 37 days and is at 9% now

  I saw there's been updates in Run+ and recorder not so long ago, was something changed ? I went for a 1h25 minutes run with batteries fully charged. I had AGPS with gps+glonass, the BTHRM and using the run+ app. Back at home, I checked the battery after a shower, and it showed 71% left ! Still, during the run itself, the battery gauge, visible in the run+ app, went down to 1/3. Is that something I should be worried about ? I have an almost 3 hours race coming this weekend...

  I had lots of fun with this one:

  Not supporting LSD here, btw. About listening to surroundings while exercising, I have to mention that bone conduction earphones are pretty trendy amongst runners and cyclists... It's a bit like having a background music in a movie, while still being able to hear perfectly clearly what's going on around (except if you put volume really too loud). https://piped.video/watch?v=M3xrcsCGnSY

  Thanks for your help ! Obviously the culprit was the wake-on-twist. It is very handy while running, but the power draw being so high, it can be advantageously replaced by wake-on-tap. I did a short test run today and I realised 1)I don't need any backlight if running in daytime. 2) Just this might be enough to save enough energy to handle 2h30 in a row. I'll test that next week with a long run.
  If it's not enough, I was thinking that the recorder app has a "time period" settings. I've set it to 1s, but do you think setting it to 2 secs would save a fair share of energy ?

  Reading this topic, I was thinking about the run+ app.
  It draws quite a bit of energy. If I understood correctly, by changing the the code so that it updates only some parts of the screen, it would become more energy efficient ? At the moment I'm often doing 1 hour runs, which wastes roughly more than half the battery (using gps update every second, and an external bthrm (internal off)). In a month I have a half marathon, which should take 2h30. Besides running faster, do you have any advice to get a chance of finishing the race without flattening the battery ?

  About water resistance, being able to swim with it would be great, but without going that far, resistance to washing the dishes and shower would be good. I happened to run under medium rain and I took it off because I was too worried for it. I'd be happy not to worry for so little.
  Also +1 for gps. Altitude is also very imprecise in my runs, I think it's related to another captor (baro ?)

  In the "read more" section of "Bluetooth Heart Rate Monitor" app, in the app loader, you'll see that it works with these ones:

  • CooSpo Bluetooth Heart Rate Monitor
    
  • Polar H10
    
  • Polar OH1
    
  • Wahoo TICKR X 2
    I'm using the Polar OH1+ to run, for almost 2 years: it works just fine.

  Waow, it works great. It's reactive, looks nice and works as expected ! Thanks to all of you, you made my day and year, because I'll be using this app two to four times a week. I hope others will also get benefits out of it. I looked at the code, you did a great job at making this work efficiently. I can't decypher it all, but most of it makes sense, or at least I can guess what it means. It would have required a year of fiddling before I approach something that barely works.
  I went for 1 hour run, and the battery handled it, but it may have a sligthly higher toll on the energy draw (compared to the run app).
  I think anyone who tried run+ will agree: swiping between both parts of the app with a single direction swipe impacts negatively the UX.
  What more ? Bucket list...
  At the end of the race, I'm patient enough to go back home and check all the details, but it's only because I have no choice, otherwise, I'd be delighted to see the run stats, namely the percentage of time spent in each Karvonnen zone, average HR, distance, time, average pace, ...

  hey @user140377 , yes Karvonnen works for all sports and maybe some cycling apps may get benefit from using this.
  As the next gen of banglejs will be waterproof and will contain a much more accurate gps and HRM (we all have dreams), it will be the perfect companion of all triathletes and sportsmen. That's where the Karvonnen will really shine :).
  On a more serious note, when I run with a Garmin watch and export the data (.fit) in GoldenCheetah (libre software to keep track of performances) , the time I've spent in each HR zone is automatically calculated, not with the .gpx of the banglejs.
  I'm off for a test run+ ! Thanks for the fix Ganblejs !!
