Yes, sensors and what not, that use BT/Ant will cause the unit to use the battery more, navigation also runs it down. That said, your ride was 4 hrs ?, most of the recent Edges - 540- 840-1040 etc…, will go 20 hrs. minimum, so you should have a few days. My 1040 goes 30 hrs, I have a Varia plus a speed sensor plus a DI2 connection.
