GPS Navigation via Google Maps
i was driving about 50km trough the countryside today and tought i'd use this chance to make a GPS Powerdrain Benchmark
Google Maps Navigation works fine even with screen off (you can see in the graph, the first 5-8 minutes were with screen On, then off) You only get Voice notifications on where to go. Google Maps uses GPS and Mobile Data but does all the calculations in the cloud, therefore no hughe CPU load.
It took roughly 57 Minutes and the Battery dropped from 85% to 78% (ca. 7% per hour).
The average Powerdrain was 1.16W

The Graph shows in Blue the meassured value (every 100ms) and in red the average over 25seconds.
There should be a TimeIndex at the bottom from 0 to 57 Minutes.... but well.....
If you have 22'066 Data Points in 57 Minutes you can set a Maximum Space of 255 points (again these 25 seconds) meaning you have 2 numbers shown per minute, aka 114 values on this short graph.... simply to much!
The "cleaned" average with only Screen off powerdrain would be 860mW
