Where is the Barometer? How do we know it's in the phone?
Similar Question... Why does the phone have/need a Barometer? lol
Galaxy Nexus barometer explained, Sam Champion not out of a job -- Engadget
Go to the Market , search "barometer"
Suposedly it inceases accuracy/speed of the gps. I havent seen any proof that its in my gn lol
Honestly, id rather not have a useless marketing feature in my phone draining the battery.
Its a Bosche BMP180 according to the 'Android System Info' app.
The barometer is a very useful feature when you have the GPS enabled
To get a GPS coordinate you need 3 positions. X,Y,Z. Your phone can estimate X and Y based on cell towers. The barometer allows it to estimate altitude (or Z). So it allows for quicker GPS positioning. When not using GPS, I doubt it is turned on.
It doesn't waste battery. Basically it turns on when it tries to get a GPS lock and turns off after.
Thing is, i use my gps daily and havent noticed it being more accurate as far as my positio goes than my bionic was.
It does not help in accuracy, just quickness in acquiring positioning.
Correct. Instead of guessing altitude, your phone now has the ability to get your altitude coordinate.
It's in there and will probably be more helpful as software is improved, as it's most likely a very software driven device.
It also helps improve our weather forecasting apps data.
My old magellan meridian gps (2001) can get an altitude reading faster and update more often from the gps constellation, too bad that thing doesn't have updated maps otherwise I would still be using it.
That thing was da bomb. I could load it with marine maps to use on the water as well as on the road.
Basically a barometer is not needed to get altitude with a "good" gps unit.
