GPS accuracy iOS 13 and/or 11 Pro Max

Must be the phone. I’m have the same car, SIM card, same apps (maps, google maps, and Here WeGo) just changed the iPhone from SE to a iPhone X and with this last never had a route planning that went more or less ok... sometimes more than 100m away from where I am... it’s impossible to trust in the iPhone X when I need to travel. Going to buy the cheapest android to gps use...

So I downloaded Strava and GPX Tracker on my iPhone 11 Pro. Strava has an option for background app refresh under general settings, but GPX Tracker does not. So I am not sure if that would be a problem for GPX Tracker. For Strava make sure that is turned on. But more importantly, neither app seems to have GPS filtering. I am not sure what the scale is of the tracks that people have posted, but if it is zoomed way in then it could be because of GPS inaccuracy - it is never gonna be perfect. In my house now GPSdiagnostic says +- 30 feet. So zoomed in it jumps all around.

mrich75, how does Google Maps work in your car? I told you that you are zoomed way in and GPS has an inherent inaccuracy, which may indeed be worse in the 11 or 11 Pro than the 6. But Strava does no GPS filtering. and without that it will bounce around.

I just upgraded from iPhone 6s to iPhone 11 Max Pro for greater GPS capability. I use GNSS for work and hobbies.

Subpar: The signal is chaotic and unusable. There is no comparison to a Samsung Galaxy Note10+ or other Android recent phones that we use at work. Clearly, I like Apple, I would love if they could improve this aspect. Broadcom BCM47755 GNSS Chip brings great hopes for instance.

I'm considering changing phone now because this GNSS feature is essential to my work and hobbies. I'll wait for few weeks, for any announcement from Apple. Maybe the hardware is fine but the software needs an upgrade? Is there anything that I have missed in the phone settings, any upgrade or subscription possible?

Also, the only information I was able to get while shopping was GPS Built-in. I wonder what kind of hardware is used for GNSS tracking and what kind of software settings could improve the accuracy of the signal.

I like the feeling of Apple's products. I don't want to have to change.

I'm not sure what you think is going to happen by constantly crying about this here. TALK TO SUPPORT. They are the only ones who can resolve this for you.

I do not have this problem with my 11 Pro Max, not any of the ones in our lab and neither does anyone else I know. Strava, GPS... all works fine.

Stop presenting this as it is an issue that every 11 Pro Max has. You need to read the TOU again.

I have got two iPhone 11 Pro and both have the same problem. I guess most users will not recognize it until you will be routed wrong during navigation. I personally have no problem with navigation using google maps, but my GPS tracking (hiking) is horrible - but only compared to older iPhones (before the X series) or other manufacturers. I guess most of the users will not recognize the problem during normal use until you have explained it to them. Therefore it is good to have such a board and to discuss it officially.

GPS is working so far, yes, but the accuracy is bad. It was better with my iPhone 6s.

I don't disagree with anything you've said here. I do disagree poor75 above in his methods. Threatening, speculating.. etc.

All of my employees have 11 Pro Max' - the screen size is required for the work we do. We've been delivering cell phones to in-need and critical infrastructure staff for two weeks and we haven't had a single GPS issue.

The blanket statements and disruptive behaviour by our good buddy do nothing but make people turn away from this problem. Catch more bees with honey than a pile of rich.

Yes, it’s not exclusively affects 11pro or 11pro max... mine X has the same annoying problem. Impossible to plan a route and achieve destination with no issue...

if it is a hardware problem, they will never resolve the problem for us

Your hiking app is not doing GPS filtering. Strava and GPX something have no option for GPS filtering. Guru Maps Pro does (it is settable and it is a great app), and it works fine as long you wait for the satellites to acquire. I would guarantee that google maps *is* doing GPS filtering, and the fact that it works for you in the car with a weaker GPS signal points to the hiking app as a problem. What happens if you do your hike with google maps? Does that work? That would be a good test.

mrich75:

If google maps works horribly in the car then you have a real problem with the phone and you should get Apple to replace it. But your zoomed in tracks with no scale may be normal since GPS is not perfect. There is always about a + or - 20 feet inaccuracy and it will never be perfect. And you expect perfection.

Using Google maps to track my hike is unfortunately no solution as I need the tracked data in my Polar account. I guess google is not able to export it to Polar.

But thanks for the recommendation and explanation

redmonk78 I would suggest trying different hiking apps. I use Guru Maps Pro and like it a lot, but there is AllTrails, Trails, and others. I didn't suggest google maps as a long term solution, just an experiment to try once or twice.

All apps that I have tried have bad tracking with iphones.

I bought GPS Diagnostics today: my brand new iPhone 11Max Pro has an accuracy of... 214 feet!

The position moves from one side of the street to the other. Then onto buildings and it goes all over the place. I don’t get these results with Android phones who have dual frequency GPS chips. I get then a precision under 1m (3 feet). The information isn’t available online but I wonder if iphones ever have any GPS hardware chip.

I have a 14 days return policy. Please Apple don’t make me go through this. I really like your company.

Windymi, did you have location services turned on for GPS Diagnostics? Because + - 214 feet is what it comes up with when you first launch it. Are you getting any satellites? Inside my house it varies between + - 50 feet and then it settled out at + - 16 feet for an iPhone 11 Pro. All satellites are green. If location services is on then it is really a defective phone.

Make sure location services is on.

+ - 214 feet is with no satellites. I get at best + - 50 feet with 4+ satellites which is not great anyhow.

Nathan do you work for Apple by any chance? What is the GPS hardware of iPhone 11 Max Pro? Is there any GNSS chip at all?

50 feet is actually pretty good, 31 feet is the best you are going to get.

No one in this thread works for Apple, this is a user-to-user technical support site operated by Apple.

You best chance of finding an answer to your question is find an iPhone 11 Pro Max teardown (probably at a site that cannot be mentioned here), see if they identify it and then go to their site to see what is on it.
