    G,day, .. anybody using the sena units out there for intercom purposes , I have the sf4 and sf2 .. both have given me nothing but trouble and continually warn me of low battery , we don’t use them for any other purpose , just intercom . So I’m wondering what I should get out of a full charge , I’m sure they told me around 11 hrs .. I’m lucky if I get 2 hrs from my sf4  .. and low battery warning at random times .. sometimes 20 mins of switching on , sometimes a bit more .. wife’s sf2 gives low battery warning  at slightly longer time but seems to stay on for quite a while , mine is pared to my fone but I don’t use it .. hers is not pared .!

    I have the HD/Sena units (20s Evo) that pick up the HD infotainment system on the Road Glide. When travelling with mates that have Sena/compatable headsets we pair up for comms.

    They last for a good days ride ie. 8-10 hours. Recently did a 3000km trip to Adelaide and back with a few long days and had 0 problems.

    My Sena sf4 once fully charged is good for about 10 x hours, that includes navigation and constant bluetooth music, no intercom.................once low battery warning comes on it is still good for a few hours

    my S20 will run easy 10 hours, that is music the whole time and intercom with the missus over on her bike, the odd phone call from people that don't know I am on the cruise

    I don't pair it the bike as I don't like the speakers at 115 or my phone to the bike and I don't like the use of the phone maps or data, I'd rather the bike GPS do its job for free
