Ugh...anyone else dealing with the infamous iOS 13.6.1 massive slowdown & battery drain? I've got an iPhone 11 Pro & a MBP both of which have been made just about useless with this crap.

@FayreLylith
Try these fixes..
Most likely the phone is over heating, and slowing it self down

@corlin Rog...I'm not sure that's the issue-the phone isn't warm to the touch (in the past it has heated up with use). The update seems to have created more of a problem than it solved. My laptop is virtually useless. It took about 10 min. for CoSo to load, and I can't stream anything on it because of the lag. I'm pretty ticked about it.

@FayreLylith
ok, first off. I believe you.

My concern is something is running a lot of cycles. could be malware, or other bad software. The fact that it is both the phone and the laptop, is very suspicious.

Very hard to diagnose on chat.

For the laptop it should be fairly easy to revert to an older system, without losing any data, or settings.
the phone is a bit tougher to do that.
But it can be done.

do a search to find out how to downgrade to an older operating system.

@corlin Thank you-much appreciated. Turns out it was something with the (very small) network I have here. I recycled the modem & router, and that seems to have cleared the issue. I'm running sophos as my antivirus, and want to shift that do bitdefender, but I need to circumvent apple's "you can't download anything unless it's from the Apple store or an id'd developmer", which bitdefender seems to fall outside of...?

@FayreLylith

hmmmmm.🤔
bitdefender is in fact in the app store.

@corlin ....Hmmm...that raises an interesting ?...I didn't use the App store-signed up w/bitdefender & they emailed a link. Downloaded the program, but it was prevented from installing b/c it wasn't from the app store or an "id'd developer"...
