ChrisOfTheNorthWest and DarrylW4 have a pile of topics for the four hundred ninth edition of the GeoGearHeads. Limax's email kicked off the feedback with a little about how he and Pifflebear handle their DNF logs when caching together. The next email was from IN_Darel was asking for more info about previous topics – smartphone battery cases and ANT+ on the iPhone. Tick_Magnet commented on YouTube about location problems on his iPhone X and his good experience with the GPSMap 66i. We had a couple more questions through our website from new Listener wakkobear about GPSRs and power trails. MikeD emailed the "Apple advises iPhone 5 owners to update to iOS 10.3.4 by November 3" article (which was very much like the "Apple warns old iPhones, iPads could hit GPS rollover problem" article). "iOS 13's Dark Mode Extends OLED iPhone Battery Life, Test Confirms" showed how darkening an OLED screen can extend battery life. There was also an article "Apple Watch calls 911 after New Jersey falls off a cliff on first date." Data Wrangler email about the stats from Project-GC about souvenirs. Then we wrapped with a couple on GNSS stories – "EGNOS GEO-3"s launch satellite has solar array problem" and "GPS III Ground System Operations Contingency Program nearing operational acceptance." The live video session from this live stream can be found on YouTube. Subscribe to the feed: Apple Podcasts RSS Stitcher Email: [email protected]
