    Hello,
    Hasn't anyone noticed a lot of apps reloading?
    I am using an iPhone 6s that used to keep as many as 30+ apps in memory like a champ on iOS 9 but it hasn't been the case since I upgraded to iOS 10.
    After I wake up in the morning most of my apps are suspended save for 3-4 of them so definitely there is something wrong.
    Can I say there is a memory leak?
    I remember android lollipop 5.0 had a similar issue then google admitted that it had a memory leak that wasn't fixed until 5.1 a few months later.
    What about your experiences?

    I experience way more system springboard reloading on iOS 10 than on iOS 9. This happens on from first beta of iOS 10 all the way to iOS 10.0.2.
    I say memory leak is a reasonable guess.

    Also there are a lot of JetsamEvent logs (multiple on every day) on my iPhone 7 indicating low memory. Strangely on iPad Air 2 the last one was at 09.13, more than a month ago.

    I also have TONS (25-40) of jetsam logs everyday on my iPhone 7. And every morning after leaving the phone plugged in overnight it seems all of my apps have closed and all of my safari tabs need to refresh. My iPhone 6 on 9.3.5 would have maybe 1-3 jetsam logs per day sometimes none. Something isn't right. Hopefully 10.1 fixes some of these issues.

    Mine is about 100 or even more in just a week, and 50 in a day.
    something isn't going right. Something is not right.

    No problem on my 7+ 10.1b5, and no JetsamEvent log (well, I have 2 events a day but when looking at them, I can see that it concerns Watch OS)

    7+ (32gb) here - many many jetsamevents.. I noticed, that my iPhone gets slightly warm right under the camera, even with light usage.

    There is definitively a memory issue here as well on my 6s+. Safari tabs reload way more frequently. I can't open 5+ pages without a reload if I comeback to the first page I open. Same thing if I open many apps. I'm realy disappointed because I bought a 6s+ essentially for the 2GB RAM and it worked perfectly on iOS 9 but on iOS 10 there is definitively a decrease in performance for multitasking.

    Its normal if you have no problem on the 7+ because the phone have 3GB of RAM.

    I had a similar issue in the past, and reported it to Apple. I received the following response:

    "Jetsam events are not necessarily indicative of any problem on the device, they are the standard way iOS deals with low-memory situations. There is no paging or swap facility built in to iOS, so apps and services using too much memory are jetsammed. Most often, apps and services are jetsammed from the background. A foreground jetsam appears like a crash, where you are returned to the Home screen.

    Jetsam events are also recorded on watchOS and tvOS, which have the same memory management systems as iOS. This likely increases the number of these logs that you see. It's also important to note that these logs are marked as purgeable space, in the event storage becomes constrained on your device they will be deleted.

    All that said, just because background jetsams aren't necessarily indicative of a problem doesn't mean they definitely aren't. We aggregate and review all jetsam events recorded by iOS devices where Settings > Privacy > Diagnostics & Usage > Automatically Send is enabled. Jetsam events from your Apple Watch are automatically synced to your iPhone, again for aggregation and submission to us. These submissions are completely anonymous, and allow us to monitor for trends and regressions on these platforms."

    I didn't say there is a problem because of the jetsam events but because memory management isn't even close to what it used to be in iOS 9. And jetsam events only confirms that.
