INRIX is working hard to provide our members with the best of both worlds: the ability to notify you of upcoming traffic influencing incidents, like accidents and police activity, while limiting the drain of your phone’s battery. The app does this by using Apple’s Location Services functionality that allows us to use cell tower triangulation, and NOT the battery-heavy GPS chip of your phone.
Details
Let’s start with a shared understanding of the Location Services feature. Counter to common misperception, the Location Services icon in the status bar does NOT necessarily equate to the use of your GPS chip. The Location Services features uses a potential mix of Global Positioning System (GPS), Wi-Fi and cell tower triangulation to determine your approximate location. Location Services allows all of your apps to provide you much more relevant content and answers. In some cases Location Services calls on GPS, for example when INRIX Traffic is open and in the foreground, so we can determine the exact road you are on, but at other times Location Services uses only cell tower triangulation, such as when INRIX Traffic is in the background monitoring for incidents on your behalf.
Screen shot of Apps using Location Services
To see all the apps that use Location Services, go to your iOS Settings app, then click on Location Services. A purple arrow icon next to the app will indicate that the app is currently using Location Services (even in background mode), while a gray arrow icon indicates that the app has used Location Services within the past 24 hours.
INRIX Traffic uses Location Services in 3 primary ways.
I. INRIX Traffic open:
When the app is open, like other navigation apps, INRIX Traffic uses the highest granularity location services, which typically relies on the iPhone’s built-in GPS services.
II. INRIX Traffic in background, alerts on, while driving:
When the app is in the background with traffic alerts on, the app may occasionally invoke your GPS chip. In our in-house test runs, we notice a typical battery drain from 100% to 96% percent over a 30 minute drive.
III. INRIX Traffic in background, alerts on, while stationary:
While you are stationary with the app in the background with traffic alerts on, Location Services rarely, if ever, directly invokes your GPS chip. In our testing, we have found battery drain to go from 100% to 97% percent over an 8 hour period.
While having the arrow in the status bar could be considered annoying, instead you should consider it reassurance that long as you see it there, INRIX is monitoring the road network around you and preparing to warn you before you find yourself hitting any major accidents or delays that would otherwise ruin your normal commute.
Happy and safe driving!
Just got the upgrade, Thanks.
So how about explaining why INRIX uses location services even if the App IS NOT running in the background? I like the idea of live traffic alerts, but how about giving me the option of shutting that off when I close Inrix completely. There is no need for live traffic alerts if I choose to close Inrix (not running in the background). Thanks.

Hi Eric.
You are correct and indeed, this is the fix in the latest version 3.5.1. Specifically, when our members turn off traffic alerts, the app now turns off location services.
If for some unknown reason this is not working for you, please email us at mobile feedback@inrix.com, since it appears fixed for tens of thousands of other members who have already updated to v3.5.1

Kevin,
I’ve sent you an email. Thanks for your help.

Also, the issue isn’t that my location services doesn’t turn off when I turn off the traffic alerts; turning off traffic alerts does indeed turn off location services. The issue is that the location services remains activated even when Inrix is closed completely (not running in the background).
Is it your intention that traffic alerts (and location services) remains active 100% of the time when Inrix is closed completely? If so, I suggest leaving it to the user to decide when traffic alerts remain active (by leaving Inrix running in the background).
I’m wondering the same as Eric, why, even if the program is closed must location services remain on? Quite annoying that it does that. The app should only use that service when I allow it to, ie when I’m actually using the app. Is there anyway to fix this? Or will I have to resort to shutting off service every time I’m done using the app?
Hope you can help
