Please provide a sample project to inspect.

If you cannot provide a sample repo, there’s no way to isolate if this is due to capacitor or a users app itself.

As I’ve stated in other issues/discussions/forum posts… debugging is key here.

Use the devtools provided by the browser and inspect your app. Any performance issues that could appear are often due to the app and not capacitor.

Oke will try to share it ASAP.

I’ve just opened #3485 and at the end I noticed that when using a remote server, on iOS Capacitor works correctly but on Android it looks like it runs on a web platform, not natively. Maybe that’s related to these performance issues. You can check by opening the device dev tools via chrome://inspect and checking for window.Capacitor.isNative. If it’s false for you guys as well, then maybe this has something to do with it.

I can confirm it too. I’ve tested on multiple android devices, quite new actually and same! Even tested on an older phone, Galaxy S8+ and same! Capacitor on Android is totally unusable…

I’ve tested on pixel 2 xl and its very laggy. On Virtual device and real devices.
