Rally RK210 travel mode and battery life

After using travel mode with my new Rally RK210 pedals, the best work around I've found to get the out of travel mode is to carry and portable charger with usb c cable for the charging adapter and power up the pedals. What is the battery life expectancy of the pedals when they are not in travel mode and traveling to the trails. This seems like a design flaw. Thoughts on if garmin has any plans to fix this in the future with a software update?
