Thank you ifixit!!! My son’s Cozmo appeared not to be charging and we couldn’t connect to it via iphone WIFI at all - I thought from reading other site posts that the battery was dead!! After reading here about home WIFI interference I took the little chap (Cozmo) to a point further from my hub and repeaters and……. I could connect to it via iphone WIFI then I was able to link to it via the app and update its firmware etc.

He still shuts down if I get too close to the WIFI think spots, but otherwise he’s fine. We’ve run down the battery several times and it’s lasting longer and longer. Thanks again - that saved a toy from the bin!!
