I am using an iPhone 6Plus or an iPad Mini 2. I frequently get 'High CPU Usage' on the device and teh latency becomes > 1s.   I've made sure all background apps are closed prior to flight -- that doesn't help.

I didn't have this problem with the Mavic Air, just the Mavic Zoom.

Thanks

I didn't take one as it happens, but this is from the flight records. As you can see I just started the flight and it's on an iPhone 6Plus.

the iPhone 6S definitely shouldn't be running into that wall.    you may have apps wastefully using CPU a lot.  for me, facebook related apps were terrible, i had to uninstall mine from my flying devices.

I fly w/ 6s + 32 Gb in airplane mode and wifi ON and always clear cache and images on DJI GO 4.
I've never experienced lag or High CPU usage.

Thanks for your input. I don't put it in airplane mode but I do clear all the running apps out first.

clearing them out with swiping them off doesn't kill them all the time, specially apps like facebook apps which can have hidden background services chewing up stuff still, in fact i found out weather underground app was causing me issues on my iPad mini 2!  because it was doing something in background even after was killed..

Here's what I do. Clear out cache in Dji app, clear out flight records and only keep 30 days.
I do this on both my iPhone 5s and my iPad mini 2 wifi version and I haven't seen the message since.
Btw I do this every month.

OK... I was flying with the mini 2 on a cell plan and it would always be overloaded.  Tried it on an LG G Pad that is a few years old -- no problem. I'll give this a shot. Thanks!!
