minus-squareturmacar@lemmy.worldlinkfedilinkEnglisharrow-up6arrow-down1·12 days agoGPS is a passive receiver. There’s processing going on, but you dramatically decrease energy use by just updating less often. It’s not like you’re sending a signal to space.
minus-squareprenatal_confusion@feddit.orglinkfedilinkEnglisharrow-up1·12 days agoI am aware of that but somehow expected that it still took more energy to receive until there are enough SATs available than to do a BLE scan. Just a gut feeling though and only receiving should have a bigger impact than I thought. Makes sense!
