Can you please specify, which version of the DJI Go 4 App you were using? Because as of today, a new version of the App is available (4.1.11) which might address the issue you just described.

Please make sure your mobile has enough space and prevent it from direct sunlight with a sunshade or a monitor hood, it will be helpful.

I've been using IOS 11 since June (beta) with zero issues.  might want to check your cache settings in the GO4 app.  make sure it's set not to exceed the available memory on your iphone.

I had this message a couple of time a while back, RC, OtG, iphone  5s with current app back then.  No problem controlling and app stayed up. I suspect heat but cant  be sure.

No it has a point....I had the same warnings on an iphone5s witch i tested in a warm environment....I phones when warm up from the sun or the environment triggers a switch in the phone witch underlock the cpu in order to prevent damage from heat....In that case dji app can not use the cpu in foul ghz......so it pops up that massage and lag starts......

No the app crashes and spark flys normal with remote but you must have it in your los in order not to make a mistake and bring it back

Keep your ram clear, ie exit all apps running in the background. iOS is great for multitasking but it eats up a lot of memory. DJI Go 4 is a memory monster.

Whenever i ve gotten this error message the app didnt crash, the RC remained connected, the spark didnt seem to be affected and video / telemetrykeot streaking on the phone.  As a precaution i returned and landed anyway.

Now i always make sure i close all open apps before the first flight and shutdown restart the phone
