Battery Life

Hi F5 plus owners,

Would be good to get an idea of battery life with a mix of activities/functions. Would be helpful to understand why the expected life has dropped vs F5, if it's Galileo/ new chipset then no way around that, if they assume music use alongside activity, I would only rarely use it, certainly not when cycling. If it's cpu load due to maps, would only need those in unfamiliar territory i.e. not regular routes, etc etc.

Thanks
