I dont really care about battery %. I want to know much time I have left given a historical shift profile. Send me a notification to charge my battery if any of my next 3 rides will end up in a dead battery.
I shouldnt ever need to check the app to understand battery life--this is something SRAM should manage for me in a push notification ON MY PHONE (not garmin/wahoo, etc).
This is not really possible because it depends on parameters which the axs system don’t have. Temperatures are very important, of course the track and in addition the voltage is not soo clear. By this reason you often have drops in battery % also at nearly all devices with battery lifetime view.
