    Just confirmed . Apple also slows down the phone when you are in battery save mode on iPhone X . So if you are on battery save mode all day until the charge reaches 80% at which point it turns off automatically, you are using half of iPhone performance

    Low Power Mode has always done this on every iPhone except the 4s, probably because it's already pretty slow.

    I was always under the impression it turned off unneeded processes not slowing down the speed.

    It does both. It's easy to miss since it doesn't say anything about slowing the processor down.

    Jesus Christ this has reached complete new levels of idiocy. Of course low power mode throttles the iPhone. It’s designed to do that.

    Low Power Mode is designed for one thing: to save battery life. If you enable that mode and wonder why the CPU performance is lessened, you’re either looking for a problem where there isn’t one, or you genuinely don’t understand how hardware works.

    Regardless, it’s a really silly thread to start, as ultimately you’ll either come across as an ignorant or a hater. Or perhaps it was an ironic post that flew over my head, in which case I’ll retreat to my cave and assume the foetal position. ;)

    Really? OMG I’m switching to Android. At least their phones do the same thing!!

    How many more threads do we need on this ridiculous topic?

    If a process were unnecessary, why would it be on in the first place?

    It's not even the same topic per se, but something that has been around and known for some time.

    Setting aside that the premise of this thread is absolute nonsense, battery save mode turns off things like automatic background refreshes for apps such as mail.

    How else would it save any significant amount of battery? Why would use you battery save mode at over 50% battery anyway.

    It's only an issue if Apple FORCES the CPU to slow down permanently, like on the iPhone 6S.

    They don’t PERMANENTLY slow down the processor, wtf are you talking about?

    Posted from a 6s...

    Next people will be complaining that I didn't ask for battery degridation when I bought my phone .... oh wait all ready have.....
    Or that a depleted raging battery cannot supply the required current to run a device (any device) at it maximum potential - even though the fix is as simple as changing the god dam battery for a new one.

    If you don't like the device buy something else.

    Call it smart power management by Apple or whatever you'd like. It's throttling nevertheless. And the end user can't do much about it.

    There's a difference between not being necessary and being purposeless.

    Haha I love how fired up people are getting over this. Of course I would expect the cpu to be throttled on low power mode. Laptops do the same. What’s the difference? Either your phone lasts longer or it doesn’t.

    Jesus isnt here but this is what apple is telling us:

    Low Power Mode reduces or affects these features:
    Email fetch
    "Hey Siri"
    Background app refresh
    Automatic downloads
    Some visual effects
    Auto-Lock (defaults to 30 seconds)


    https://support.apple.com/en-us/HT205234

    Only idiocy it is to trust anything apple says. So, how much more they hide from us that we should know?
