I am experiencing the same issue after I updated HA iOS app to 2024.3 (iPhone12).
App is slow, touch inputs takes time to register, page loads and navigation takes time and scrolling is stuttering.
I finally got around to getting python updated to v3.11 and home assistant to 2024.4.4 & the app is now very sluggish. It’s the same across other platforms as well, I have two Galaxy tablets used as wall panels and Home Assisant is behaving the same way on them as well. If I access home assistant via a browser, there’s zero lag. The wife and I are both on iPhone 14 Pro’s.
My problem has seemed to have resolved itself, at least for now. I did do something but I’m not sure if it’s the reason why I haven’t seen the slowness, but if everyone else is still experiencing the problem then maybe it is related in some way.
I had another much larger problem with a DLL (Qt5GuiVBox.dll) that was causing my VirtualBox VM where my Home Assistant instance lives to become unresponsive daily, sometimes multiple times a day. This problem was not exclusive to Home Assistant, I have another VirtualBox VM running a Plex server and it too would become unresponsive until I had to manually reset the VM. Unfortunately there’s very little info on the app crash relating to that DLL so I was kind of stuck and was planning on just building a linux box and doing away with the VM’s. If this ‘fix’ keeps up then it will allow me to delay building the dedicated box for Home Assistant and other services to live.
I have the program WinAutomation (now called Microsoft Automate) and I made a very simple automation that pings the local IP’s for both of my VM’s every minute and in the event of an unsuccessful ping, it’ll reset the VM and also send me an email letting me know it has occurred.
Since making those automations 3 days ago, I’m now actually able to use Home Assistant in the iOS Companion App and also my Samsung wall tablets as expected, and neither VM has required to be reset.
I will report back if the problem shows itself again.
i have similar issues as well but for me its not only the app. Also the web interface lags for a few weeks now. lights turn on very late when pressing a button (zigbee2mqtt), opening devices sometimes take several seconds. Perhaps a HACS integration is missing things up… going to disable them all and see if anything changes
Same problem with, running HACS on hyper-v, very slow on ipad and iphone,
Normal response on MAC and Windows PC
Became unusable on iPhone, IPAD, particular on the main page with all entities it takes minutes, to build the website in the meantime it is frozen
