Running Beta 5 on an iPhone 6S Plus. I’m using a Gravitas Dock; I’ll get a pop up saying ”this accessory may not be supported” and charging ceases; and the battery (if I’m not around) will drain to zero. Very annoying. Reporting this bug. Is there a fix to prevent it happening? I can dismiss it; but it will return spuriously; sometimes during the night.
Interesting feedback, but forum posts aren't bug reports. Individuals using betas are free to use the Feedback Assistant; devs can use the 'Report Bugs' link, below right. Just keep in mind that it is common for betas to lack full power management, etc.
As well, you may want to move this to the forumiOS 11 beta, thanks.
