  • How iPhone batteries work, and how Apple manages performance over time

    dws-2dws-2
    This is the best article I've read so far. It's nice to get more information. Keep up the good work.

    I'm wondering if the "critical voltage" is higher on the iPhones 6  and later (vs. the 5s and earlier) because that's when the issue started. Maybe newer processors, being more powerful, need a higher critical voltage. Also, iPhone batteries tend to be smaller (iPhones being more power efficient) than Android batteries, and bigger batteries are less affected, so I'm wondering if this is less of a problem in the Android world.

    At the end of the day isn’t the issue that Apple needs higher capacity batteries in their iPhones? 
    We don't know the issue. I'd really like to read some reporting that answers these questions:
    1. Is there something about the processors in iPhone 6 and higher phones that draw more peak power, so are more subject to shutdowns than iPhone models before the 6? (In other words, does an old iPhone 5s not shut down during high power draws while the iPhone 6 does? Sometimes a processor innovation may have unintended consequences.)
    2. What exactly would cause the phone to shut down if it wasn't throttled? Is the processor not getting enough amps or volts? Could batteries be manufactured that would provide enough headroom to remove this issue? (For example, being capable of supplying the necessary amount even as the battery ages.)
    3. How is this slowdown tied to battery capacity? For example, will a battery with 90 percent of its capacity (not current charge, but capacity) always work at full speed, and a battery with 70 percent always be at a slow speed. How does current charge affect the processor speed? 
    4. Does this issue happen to Android phones? If so, how is it handled? So far we just have assertions without any research.

    I feel like we don't really understand why this is happening yet.

    You bought a machine rated at 3.2 GHz and you’re consistently getting more than that under full load. Boost is just that. Momentary. I’m not seeing why you would expect it to function differently.
    Rubbish.  The turbo boost speed is for when you are running single threaded tasks and should be able to do so sustainably for long periods.  If you are running heavy multi-threaded tasks the turbo boost does not kick in.
    Here's some information: https://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-technology.html

    It basically says that sometimes you won't get the turbo speed, depending on 
    • Type of workload
    • Number of active cores
    • Estimated current consumption
    • Estimated power consumption
    • Processor temperature
    It seems that temperature is the limiting factor here, indicating that the processors could go faster if the cooling was better.

    The real question is whether it's Apple's cooling system that isn't keeping up, or whether the internal core temperature just gets too hot after a while, and no reasonable cooling system would help.

  • Hoping to capitalize on Apple battery controversy, HTC and Motorola volunteer that they do...

    So the question is: Do the phones just randomly crash, or do other phones not have issues with high processor performance with older batteries?

    Honestly, this was just the opposite (though communication was piss poor). It was easy to do a battery upgrade and get full speed back. For those that didn’t want to do that, it kept phones, and batteries, in use longer.

    Apple’s communication on this, however, was atrocious. 

    The reason this story has legs is because most people I know who keep their iPhones have noticed slowdowns. I believe it's 99% because of either operating system updates, software bugs, and memory getting full. 

    However, when personal experience meets conspiracy theory, it's like snowball meet hill.

    The real issue is that software updates cause older phones to get slow. Of course, there are benefits in that users get the latest features, but a lot of consumers feel tricked when their phones suddenly become really slow.
