I noticed that with my iPhone 6s there is no audio signal when i'm reaching the low bat level (mine is set at 25%). Other sounds are good to hear, fi. obstacle beeping, home point set,... When reaching the low bat level, the only thing I feel is a short iPhone vibration. Aim I missing something or is this a known bug? (it seems that this problem already excists a while , but i found no clear answer?)

Yeah that's weird. You may want to uninstalled/reinstall GO4 app.  Seems to work for me when these glitches surface.

Hi, thanks for the inquiry. May we have the firmware and app version that you're running? Have you tried to uninstall and re-install the application? I would recommend syncing your flight records and saving important files before deleting the application. Please keep us posted on the latest progress.

Thx both for the answers.
I have installed the 4.3.9 GO4 app and have the 01.00.0200 firmware installed.
Next time i go flying, i will reinstall the GO4 app. Just have to wait a few days because the weather is not good. Keep you posted.

Flown 3 batterys today after reinstalling the GO4 app. Still the same: all audo is playing (homepoint, obstacle detection) but not the low battery audio warning (set at 25%), we feel a light vibration on the iPhone when low bat is reached. We feel the same vibration when the mavic is connecting to the app. iPhone settings during flight: airplane mode.
Any suggestions to hear an audio warning? Thx...

Still no audio low bat warning, only vibration iPhone, after disabling the silent switch on the iPhone. Any suggestions?

Was testing critical low bat today… Low bat audio warning heared when bat was 22% (not on 25% as set). Will test this again next flight.

Two more flights this afternoon, no low bat warnings anymore (bat level down to 20%). Give it up, don't know what triggered the audio level in previous post.
