    Is there any way to clear the cache of iPhone 7 with iOS 10 via PC in order to gain some MBytes in the memory?
    Apps like FB, Twitter, etc, seem to store a lot of trash, and if i delete and re-install them their storage needs is 50% less but i was wondering whether i could that easily through iTunes somehow

    Cache is there to be filled with.. well, cache.. that is its purpose. If you empty it, it will just fill up again.. because that is what it's for. Leave it alone and just enjoy your device.. let the system take care of the housekeeping.

    There's a simpler way than deleting the app and re-installing to clear the excessive cache data in apps like fb which are known to grow out of control sometimes. Simply log out of fb and close the app with the app switcher. You can then launch it again and log back in but most of the excessive cache size will have been removed from the phone. I tried this recently and the size of the fb app reduced from 500mb to 200mb on my iPhone 7
    Cheers

    You can't really control the cache used by an app, beyond deleting it of course. There is an upper limit to how much they are supposed to use and iOS is particularly good at claiming back space when it actually needs it for operational improvement.

    Facebook however is a bugger and the best way to take control of it is to delete the app and never install it again. Instead just use Facebook in Safari, it's kept under control in there.

    True but cache also is full of trash and I'd rather have less cache and more apps.

    When you are running out of space, the system will do a sweep and remove some caches. When you need the space, the system will give it to you.

    Download the Memory & Disk app from the app store. It allows manual removal of cache and other things. It may be a gimmick, but I've used it for a few years. Pretty accurate too. You can give it a try. It may appease you.

    I really do not agree with you. When free space is under 500mb iPhone is lagging big time. Even iPhone 7 they I use now


    Just tried it and from 1.2G I had free space it managed to make it 2.4! Wtf? Thanks a lot bro

    It can only ‘lag’ when it acutely needs to write more data than the flash storage has reserves. You don’t usually notice this when using the device, just that it writes/downloads a bit more slowly. iPhones start to ‘lag’ when control freaks think they have to manage everything themselves. I am reaching the storage reserves on my iPhone frequently as well and it never affects my performance noticeably, only downloads/installs take more time than usual.

    Removing caches will also mean that applications load more slowly the next time, until they replenish their caches. You can’t win this.

    While I happen to agree with what your saying here there are a few exceptions where deleting the cache every now and then is better. Facebook can grow it's cache to ridiculous size given time. I've read of instances where it's grown to as much as 2gb. By removing the cache periodically the app size shrinks back down to around 200mb and takes a while to grow to those extremes again. The app will only lag very slightly the first time you load it after deleting the cache and after that you won't notice any difference so it's a worthy trade off for gaining 1 or 2gb of storage space back in this example. There is a fair argument that your better off using Facebook in the browser for this very reason.
    I agree though that with most apps the cache is managed fine automatically and best left alone.

    While I generally don't pay much mind to some frame drops here or there and the like, I have experienced a noticeable performance difference when my phone would have something like under 1 GB free compared to when it would have at least 2 GB free (for example).

    If you feel the need to go out of your way to manage something like cache because an app is "hogging" it all, then it would probably be best to remove that app. Let the device work for you rather than control you.
