hi forerunner friends,
i write wondering if any of you have experimented with the different GPS options. obviously, multi band gives the best data, but at the cost of significant battery drain. i have long (over 2 years) used All Satellites to great effect for my runs. it gave me better instantaneous pace during my runs at a reasonable battery drain. yet, i saw DC Rainmaker and DesFit recommend using SatIQ for the best of both worlds and then forget about it.
this would make sense if SatIQ was smart enough to choose the GPS mode properly, but it seems in my case, it doesn't work very well. i find it is draining almost as fast as Multiband on runs which have very clear sky/unobstructed views (with a sprinkling of runs under tree cover), and significantly more than All Satellites with no apparent gain.
roughly speaking, i drain about 3.5-4%/hour using All Satellites and close to 5% using SatIQ which is almost the same as i would get using full Multiband. have you all seen the same thing?
i'm sure a dig down into the FIT files might yield some interesting results (i don't have the tools nor time to do that), but it seems anecdotally that SatIQ is using Multiband in cases where it's likely not necessary.
