QC35 II frequently voice prompts 100% battery

Qc35 II regularly prompts "Battery 100%" and disconnects from the device and after few seconds resumes connection with device but the session with my app does not resume. I use this to join conference calls and listen music. I have to go to app and resume the session.


This has become annoying and unusable.

Hi nhkishan, 


I am very sorry that you are experiencing some connectivity problems with your QuietComfort 35 II headphones. I can understand why this is not ideal and is becoming increasingly frustrating, we would love to do what we can to get this resolved for you.


I would firstly suggest performing a reset of your headphones. Instruction on how to do this can be found below.

  • Turn off the headset and wait 30 seconds
  • Plug the headset into a wall outlet using a USB charger, then wait 5 seconds
  • Unplug the USB cord from the headset and wait 1 minute
  • Turn on the headset

Following this, check for any available firmware updates for your headphones. This can be done via a computer using a USB and visiting our firmware update website, which will provide you with full instructions.


If this shows no sign of improvements, please let us know what device you are connecting to so we can assist you with some further troubleshooting. 


I look forward to hearing from you. 😊
