I though i'll get used to it, but no, today i said enough. What's going on with Karoo 3 battery drainage? I barely can get 9-10h of battery life. It's ridiculous

I have heart rate, speed and power sensors enabled, backlight set to 25-35% most of the time and have installed ONLY 2 extensions which don't affect battery life (checked without them too)

Today i started the ride with 100% battery. After 40 minutes of ride 92% battery left and wgen i was done 4h 18 min @ 58% battery status. This is not acceptable.and see what i got on screenshots.

  Even tho I have K2, I for example found having the map navigation shown uses a lot more battery. Also the more the map is zoomed in the more it uses battery. In other words, make the map as much zoomed out as you can (to certain degree of course).

  Also you can try factory reset to basically simulate the time, when the unit was brand new. And compare the battery usage now vs. then.

  The battery on my Karoo 3 started draining very quickly and ended up swelling up and causing the screen to come off. They have no idea where to get a new battery. What do I do? Throw it away then?
