back to article iPhone 5S autopsy shows WHY it can't tell which end is up – dev

Balance problems plaguing the iPhone 5S popped up with the first reviews. But a teardown by Chipworks and the musings of an iOS dev have isolated a likely reason why the steering on that motor racing app is about 5 degrees off. It's all down to a replacement accelerometer which lacks the accuracy of its forebear. Although …

    So: develop the calibration app; install the calibration app; run the calibration app.

    Simple as that: bisch Bosch basch.

    It just works...

    It would also require an OS update, since every app using inclinometer data would want to receive calibration-adjusted data.

    But if you're spending a large amount of cash on a premium device, you'd naturally expect HQ components to be used, and any such calibration to be done at the factory.

    Or am I being picky?

    Strange, maybe mine is the older version because it is spot on in my 5s?

    I wonder if there has been a mix of them....

    Still even if it was off the lack of malware more than compensates...

    And everything works flawlessly on an S4?

    Something Apple has to do

    Apple can do this and have the core API reference the adjustment before reporting orientation to all applications. It makes no sense for third parties to fix this issue.

    Regarding its use in driving games, a 5º discrepancy would bring some extra realism... it'd be just like the steering wheel in my works Transit van!

    To quote Jeremy Clarkson:

    This can't be! Apple don't get anything wrong.

    The problem definately lies between the ears of the purchaser.

    "Apple don't get anything wrong."

    Useless strawman argument repeated by idiots.

    Don't you ever read the news? Apple does several software updates and hardware recalls per year for things it has gotten wrong, same as every other large company ever.

    what a let down given the title

    I was hoping for some sort of grainy video footage with people in lab coats and masks around a dissected iPhone

    I would think almost certainly a cost decision. It only takes a couple of $0.01 to make a big difference when you sell multimillions of devices.

    Happens a lot - constant efforts to decrease the BOM, often resulting in reduced quality.

    As the article said it's more likely to be for power saving reasons than cost.

  19. Richard 22

    Highly unlikely to be due to power saving

    The power consumption difference for the phone overall will be so minimal with this part it seems highly unlikely to be that reason. More likely cost, or the required voltage - if they don't need 2.5V anywhere else there may be another component saved, or it might make routing the PCB easier etc.

    .. Apple's latest uber-phone shifts gravity by as much as five degrees ...

    That is some serious technology!

    Oh I dunno, I know a low-tech solution which seems to do it for me on a Friday night, although often by more than 5 degrees...


  24. lglethal Silver badge

    Its not the chip's fault!

    It's obvious that the Apple/Jobsian Distortion Field is so strong on the iPhone 5S that it is actually affecting the local gravity experienced by the chip!


  25. Matt Hamilton

    Inclination...hahahah... geddit?

    "Apple could do that, as part of the production process, but has shown no inclination to do so."

    Or they have, but are off by 5 degrees.

    Nah, they choose the Bosch component because it was the only one who could fix the iMaps misdirections.

    No, no, no, no, no, no, no, no, no, no, no, no, no, no.

    You're just holding it wrong

    Yeah, I know, its growing thin. But it still scores down votes from the Fanbois

  29. I ain't Spartacus Gold badge

    Nah, I don't think it's the fanbois downvoting, so much as the terminally bored. That's an old, old line now. After all, you felt the need to use the joke alert icon on your post - which is almost as bad as laughing at your own jokes when no-one else is...

    Personally I was hoping that the story was going to be Apple had installed the sensor upside down. After all, various rocket makers have, so I don't see why they shouldn't be allowed to join the fun.

    Well done INSparticus! I'm kicking myself for not making a connection with that failed Russian satellite launch earlier.

    Watch as apple produce a similar app and remove yours from the store

  37. Doug Petrosky 1

    Just get it replaced

    Has anyone taken one to an apple store? They would have to replace it as defective or fix it with a simple configuration setting. This seems like a non issue.

    Note: I checked my mother in law's 5s and it was spot on so I can't tell you what Apple says about this issue.

    again and again... units !

    Anyone reading the articles before publishing ?

    You don't "consume 2.5 volts".
