iPhone 5s accelerometer/gyroscope/compass values incorrect
Lined up against my apple box separating my iphone 4 and iphone 5s pointing directly south, here are the readings. I did this because the stainless steel band and/or other parts of the 4 were affecting the compass when lined up against each other. I might go over to a buddies and use his iphone 5 to take pics or video. Lets keep this thread civil and on track. Please present facts only. Trolls need not reply...
There are now quite a few article's about this issue:
Both Compass's set to magnetic north:
iphone 5s reads: 165s
iphone 4 reads: 179s <--- Reads correctly compared to the compass in my cessna
Swipe from right to left to get Apples level app:
iphone 5s reads: -4 degrees
iphone 4 via iHandy level reads: 0 degrees level
2 different Johnson levels used as well. 24" and 48". I had to raise the level until the bubble bottomed out in the glass to make the iphone 5s read zero.
Have you tested this? I have contacted apple support and they suggested replacing the phone. At this point, I'm going to wait it out as I can live with this defect until I know the problem has been fixed. I spent 34.99 oh a front and rear film protector that I will have to eat when/if the device gets replaced. OCD does not alloy me to use any device naked. What are your results? good or bad...
If yours it out of spec. I suggest reporting this to apple directly to get this problem resolved quicker. They said that they are monitoring feedback in real-time, at this time
Ok so that calibration procedure had no effect on the invalid data from the senors. 7.0.2 update had no positive effect as well. Sensor-Gate is still lurking...
7.0.3 seems to have corrected the problem for a lot of people.

The other thread was shut down because of a certain user or 2 that was derailing it. This is a clear problem affects gameplay for games and apps that use the accelerometer. Xplane for instance the plane drifts to the right big time on my device. Plus or minus 1 is of for allowable tolerances but not 4, 5, or 6 many of us are getting. Don't let someone tell you its OCD and is acceptable its not at least for people who use this function.

iPhone 5S Gyro issues
I posted this in another thread and a mod immediately closed the thread for some reason unknown to me. Is anyone else's gyro not working correctly on their 5S?
Left iPhone 5S
Middle iPhone 5
Right iPhone 5
Also, this is really weird... None of the compasses are reporting the same direction.
Anyone else experiencing this?

As far the compasses all different, are they all set to true north or magnetic?
Mine 5S is off only 0.4*…….
iPhone 5s/iPhone 4s/iPhone 3Gs
iPod Touch/iPad 4/iPad Mini/

I can just visually see that mine is also in error. I guess if could give some numbers to back that up if needed. My 4s was very accurate. This level seems sloppy and loose. It does make me wonder two things:
1. Since the new M7 motion chip has a lot to do with running numbers for rhe gyro, might bad data in from a gyro that's off by significant amounts result in bad numbers on the output side?
2. Is this a software issue and easily fixable, or is this a hardware issue that might not be so easily fixed?
Update: I leveled it against a Stabila smart level. Seems it's off by 4 degrees. That's unacceptable and a significant amount- especially in light of this phone being touted as such a motion device.

Are you also seeing a jittery/jump effect when you unlock the phone? As per this thread - http://forums.macrumors.com/showthread.php?t=1643977
Could be a software/hardware issue with the motion sensors.
I'm also seeing the same thing as you with the gyro being a bit off.

I went to apple.com/feedback and submitted it as a bug item. Maybe if others do likewise we can spur a fix for it!
