    There hasn't been any problems with mine (yet) and there are speculations that 9.0.2 may have fixed it.

    iPhones 6s owners, your input please.

    The only thing that heats up in a phone is the CPU. Apple should be able to pinpoint the issue quickly. It's either a bad CPU or the software is causing the CPU to run so hard it overheats.

    Looks like many complainers were running beta software.

    A real life friend brought this to my attention. He is not running beta software and is on 9.0.2. He has the problem but his wife does not.

    So there is something to it

    Okay, so both Beta and official updates are having problems.

    Still no experience here. Must be the shield affect that my official Apple leather case is providing the phone

    And I hear there's an app that'll tell you which one your phone has.

    Yes, it's true that 50% of the A9 chips in the new 'S' series are made by TSMC and the other half made by Samsung.

    I would never download a Chinese app to determine which chip I have.

    So Chinese sites are spreading stories that TSMC (Chinese) chips are getting up to 2 hours more battery life than Samsung(Korean)?

    Hmmm.

    While I have seen Apple not admit to real faults in their phones, they are not idiots either.

    Most of this appears to be based on rumors, the kind that come out with every launch.

    Here is a new story:

    "As suspected from early results yesterday, the takeaway from Morrison and Evans' videos today seems to be that while intense cases like synthetic Geekbench tests designed to push devices to their limits can reveal significant differences in battery life between devices using the two chips, real-world impacts are much smaller and are likely to be unnoticeable to many user"

    6-11% although not as high as 22% still will be noticeable in real life.

    A 10% over 9 hours would be almost 10 hours. :)

    I consider myself fortunate that I don't have any problems.

    Ha. When I posted the link, it said 1%!!!

    I wouldn't place too much in these early numbers either way., quite honestly. Some will OCD over it, some use their phones in a way that they'll see nothing.

    But I would be hard pressed to believe that went unnoticed during development in a way that really impacts anyone seriously.

    Especially since the small 14nm architecture of the Samsung chip would normally be believed to consume less power, not more.

    I don't see where those numbers range come from. The video post of this test are still there.

    Anyways, people are freaking out.

    I call it 'LaunchGate'

    'Evans also ran a lighter battery test, playing the same hour-long YouTube video on each device to see how a more day-to-day scenario would affect each chip. In the end, he saw only a one percentage point (1%)difference in battery drain, noting that while heavy-use cases could see the TSMC chips come out on top, highlighting the differences between benchmarks and real-world usage. '

    From the last paragraph of the Macrumors that you linked to.

    In any case the battery percentage doesn't bother me but the crashing certainly does.

    I know. Those percentages were not there when I posted.

    Regardless the low end of 6% contradicts the 1% stated in the same article and video.

    Anyhow I get suspicious of any of these early consumer articles. Just the scientist in my training.

    This is Apple official's statement meant regarding chips and battery tests.

    Only 2-3% difference in real world tests.

    'With the Apple-designed A9 chip in your iPhone 6s or iPhone 6s Plus, you are getting the most advanced smartphone chip in the world. Every chip we ship meets Apple's highest standards for providing incredible performance and deliver great battery life, regardless of iPhone 6s capacity, color, or model.

    Certain manufactured lab tests which run the processors with a continuous heavy workload until the battery depletes are not representative of real-world usage, since they spend an unrealistic amount of time at the highest CPU performance state. It's a misleading way to measure real-world battery life. Our testing and customer data show the actual battery life of the iPhone 6s and iPhone 6s Plus, even taking into account variable component differences, vary within just 2-3% of each other.'

    @palandri: Yes, indeed. If it had been Mr. Dump, he would have said, "Look, you losers, our design of the A9 chip is excellent. The idiots that made it for us (Samsung and that other company) don't know their way around a blueprint.

    That is so true.

    Being a company, you can't call your customers idiots, not directly.

    Or maybe it's an Apple plot to smear Samsungs brand. ☺️

    I was following the "ignorance is bliss", theory but decided against my better judgement (TWX made me do it :p), to check.

    It turns out I have the Samsung chip as does TWX, Mr. Meanie has the TSMC.

    So what does all this mean? As far as I am concerned, nothing. From my understanding all three of us have great battery life, compared to what others are reporting.

    My 2 cents worth with a sample size of 3

    Independent and controlled tests have verified Apples claim of 2-3% power difference between processors, for typical usages.
