I have similar issue with my Iphone 7. It overheated when I was using Dji Mimo app. But my phone started to cool down significantly after I turned off the Mimo app. FYI, no background apps were running when I was using Mimo app. I don’t have this issue with other non-DJI app.

Hi I am using dji osmo mobile 3 with s21+ and I have an overheating issue. Can you please help me and tell how to fix it ?
Thanks

Hi there. Thanks for reaching out, and we're sorry for the inconvenience. May confirm if it's the gimbal that's overheating or the mobile phone attached to it? Thank you.

I'm having the same problem.  The DJI application causes the phone to overheat excessively.  I see that many people are having this problem, and I also see that DJI company does not solve it

Hi there. When the Osmo Mobile 3 is connected to a mobile device’s Bluetooth for usage, the Bluetooth module will always be on. When the camera is set with a high frame rate and resolution with the Follow and Beauty functions enabled, the energy consumption will rise and cause the temperature of your mobile device to rise. This is normal. We recommend removing the mobile phone’s case, disabling unnecessary apps, and avoiding taking high-resolution videos for an extended period. Please keep us posted if the issue persists even after following the recommendations. Have a great day.
