Since the screens are huge, and they take a lot of power to be seen in the sun, I would not expect it last for the full century..
AND more importantly, was not part of the original specification. The Wahoo RFLKT with GPS, HR + bike sensors and listening to music over BT will last just fine for an all day ride.
OP wants bike computer for real time HR and would consider phone, so it was considered in original specification. There was no mention of music or headset. My suggestion for short rides to use phone and Wahoo Fitness was well received by the OP. I'm not sure what playing music in background has to do with battery drain in this topic.
