iPhone 5s accelerometer/gyroscope/compass values incorrect

I'll repeat this again. You can't calibrate to 0, only offset the difference that will double if you flip the level 180 degrees.

So this guy had the same issues with the gyroscope/compass. His phone's screen also has problems.
However the new iPhone he got still has the same issue and the Genius told him that Apple has already informed Apple Stores that the issue will be fixed with the next few iOS updates and thus they will no longer replace phones with gyroscope issues.

Dfu
I tried a DFU restore as some here have suggested. The level is still off by 2 degrees (same as before), but the compass seems to be more accurate than before.
My guess is that the software needs to be calibrated better to the new sensor. I'm consistently off the same amount on all sides. The level app was probably programmed to the better sensor that's in the 5 and 5c. Let's see what happens when we get 7.0.3 and 7.1.

I starting to think its hardware fault with the early batches. I still think Apple needs to explain why some phones doesn't display these problems at all.
Just Google searcn "iphone 5s sensor", and you'll see several pages of reports about this issue.
I think people underestimate the importance of software with these types of issues. Software is so deeply integrated with the hardware, it's impossible to tell at times which is broken.
As with this case, I think it could be both. The compass and gyroscope are clearly working, and they're working in the right direction, but they're off by a few degrees. This is a big issue for so many people, and it must be acknowledged by Apple. However, this probably could be solved by software.
It could be the compass and gyro in the 5s are physically less accurate than previous iPhones, but this could be solved by software by updating iOS 7 on the 5s for a system-wide recalibration and recalculates all the values in all apps. It could be that the compass and gyro are sending the their calculations to the M7 co-processor, then the M7 messes it up. This could also be resolved by software by updating the firmware on the M7 chip. Even if it is a real hardware issue, I bet it can be resolved by software.
I think Apple has surely been informed about the issue by now, but they won't have a public acknowledgement so it doesn't get out of hand. They're probably working on a fix, but fixing such a problem takes some time to figure out where the real problem is occurring and how to fix it. I'll give to 7.0.3 or 7.1.

I don't think you understand. 3rd party apps make their product conform to Apple, not the other way around. Apple can easily create a fine tune setting that's saves the user setting when exiting. Frank, what app is making the iphone 5S a major deal breaker for you?
Mine is not affected. I have checked randomly many times, and have direct access to the data from the sensors as one of my apps use this data and would malfunction if the data was bad.
I do see once my app starts a large correction, however I just ignore the startup "bump" in the sensor data in my code.
I assume the bump I see in my code is the same that causes the visual effect I see in the live wallpaper and parallax.
Other than that, the data I receive, and the display of the data in Apple's own apps, is accurate and consistent.
Stating it affects all 5s phones is simply inaccurate.
That said, I do believe this is affecting a significant number of them.
Lucky
You are one of very few considering this is a wide spread problem. Did you compare it with a perfectly level surface? Cheers!!

Post your device details please. When was it manufactured, what factory, and so on.
Wrong !!
There isn't a faulty batch. I was told by an Apple Tech Supervisor that this is a wide spread problem. You are one of very few people that have a correctly calibrated device. Lucky I guess. People are having different reading such as -5, -3,-8 and of course 0 will show up on some.

What ??
What are you two trying to say? I think and hope this can be fixed by software and people aren't nit picking. We all paid big bucks for this iphone that Apple stated suppose to perform a certain way and even bragged about it's new M7 to the world at the WWDC. If it suppose to perform a certain function and it doesn't, we have a problem. I personally don't use the compass or level but would like to have them functional considering I paid a lot of money. Now the gyro for me is a problem considering I play games and now I have to offset the tilt to stay neutral. What about all those fitness apps that the M7 will allow???

All of these values can be adjusted by the app developer. Apple just needs a fine tune calibration setting. Other than that 99% of the problems would be solved because most of these people don't use their iphone as a gaming system.
probably not hardware
I really don't think this is a hardware issue. While the M7 soc is new, I don't think the other hardware bits around these are. I can't imagine that an existing supplier got a whole batch wrong. Let's see what software can do, otherwise it'll be a return and replace situation regardless.

Lets wait and see ...
I spoke to an Apple Tech Supervisor twice now regarding this issue and he stated it was a wide spread problem and that Apple was fully aware of it and as made it a high priority. He stated that it most likely software and told me to wait a couple firmware updates and if the problem still exists, give him a call directly. I've done some tests and it seems like the gyro and things are functioning correctly, just not calibrated correctly. I purchased ($1.99) an app called Clinometer + slope finder + bubble level (3 in 1) which allows you to calibrate within the app only and it maintains the calibration. I used this to test the function of my gyro and things seem fine. So all Apple as to do is have a similar manual or automatic calibration feature in IOS 7.x.x.
I fully understand why this is so disappointing. We all paid big bucks for an iphone that Apple states is the best technology on the market. I think that we need to wait for a couple software updates to see if it gets fixed. They will need to fix this sooner instead of later.
I purchased the Google Nexus 7 2013 when it was released and many people were freaking out because of the GPS and touch screen issues. Many people performed several exchanges and son on. Google was silent on the matter and then after a couple weeks, released a firmware update that fixed the issues. I'm very happy with my tablet.
An NO, I don't work for Apple. Just trying to help and hopefully get this problem resolved and forgotten. Cheers!!

I'm not Frank but for me the problem is that every photo I take, every GPS/navigation app, game, and fitness app will be filled with garbage data about my direction and speed.
Apple's keynote announced that the M7 "Enables a new generation of health and fitness apps" and Phil Schiller said about the M7 "...it takes advantage of all these great sensors... it measures from the accelerometer, the gyroscope and the compass, and with new software and applications you're going to get a whole new level of health and fitness solutions never before possible on a mobile phone".
This keynote (and specifically the M7 and new camera) were the reason I ordered my iPhone 5s. Either they get it working like they announced or they refund the cost of the phone and contract and additional costs due to their false advertising.
Why haven't you returned your iphone? Why don't you wait until they fix this bug (yeah, that's all it is), and repurchase another iphone?
I'll play along. The first feature demoed at WWDC was GAMING. I used my wife's 5s for Real Racing 3, and the steering was much more difficult compared to my ----- phone (don't want to promote one phone over another in this thread). She decided to return her 5s after seeing the Forbes article, saying she spent too much money for a defective phone. I was unable to get a 5s, and bought the only phone AnandTech has ever given an Editor's award to. When my wife returned her 5s, she bought the same phone, and played with it every chance she had this weekend. I'd like to thank Apple for that.
You can say, "Whayt's the problem?" and "This doesn't effect anything" all day long, but people have heard that enough from Apple reps enough already. Beside the compass app that Apple has on the 5s's screen, any level/compass app I installed did not work properly, nor did games. I do not agree with you that the iPhone is not used for gaming, even if it's not the owner's main gaming device. It's not like you can fit an XBox in your pocket.....
It hasn't arrived yet, but if it does have the problem when it arrives and Apple hasn't acknowledged the problem officially then it will be returned immediately and I will wait and see what happens.

I'm sure you will just love your new phones, good luck with them and I'm sure they will never have a bug in a future update.

You bought an HTC One because of a gyro issue? Good luck with that. Hope you like never getting updates....
Actually, when I went the the Apple Store, I found many 5c phones with a similar problem. Probably about 70% were inaccurate. None were as far off as the 5s phones I tested, and there were actually a few 5c phones that were properly calibrated (this wasn't the case with the 5s; every one I tested was off at least 1 degree).
Note that it's harder to test a 5c since there is no level side on which the phone will stand up on its own.
----------
From my (admittedly small-scale and unscientific) testing in my local App Store, it seems to affect both phones, but the 5s is much more prone to the issue, and much more severely affected.

See above.

Probably not.
