I totally understand the charging issue. I've talked with several people that have had the non-charging issue and I tell them that in fact is defective hardware somewhere and they should get an exchange for it. The issue this thread is focused on is the apparent non-charge, but after a hard reset (holding the home and power button for 20 seconds to reboot the ipad) the ipad works again. The ipad should show a full 100% charge from sitting on the charger all night even if it's not waking up properly. If you are having issues with the ipad pro restarting during use constantly, or not charging, then I'd recommend starting a different thread or searching for one that matches that problem because that would be a different issue and needs to have visibility into it.
So far those of us investigating it in this thread have found 2 solutions that seem to work without fail:
- Install ios 9.2 beta (hope that ios 9.2 comes out soon).
- Turn on Siri, and Turn on Hey Siri. (both need to be on).
The other things people in this thread have attempted that seemed to work for some but haven't provided as much success:
- Try a different lightning cable and charger.
- Try isolating the charger and cable to it's own outlet.
- Ensure that the volume is not muted.
- Turn on airplane mode with charging.
- Turn off back up to icloud.
- Turn on back up to icloud. (Yah, which shows that's probably not the issue).
If you are having an issue that isn't a full charge over night and then a blank screen when you go to turn it on then it sounds like you have a totally different issue and you should RMA that thing with Apple and get a different ipad pro.
For the record the full charge, black screen issue has been found to be on ipads that were new set up out of box with apps downloaded, ipads that had the icloud backup restored, ipads restored from itunes backup, etc. I.e. it doesn't matter how it was set up. If you talk to an apple genius and they are unaware of this issue or try to lump it in with a different issue, point out this thread to them (not sure if they'll read through it though).
All we can do is hope that ios 9.2 is released soon at this point. The iPad Pro is actually magnificent, and for those people with the problem in this thread it's a 20 second fix generally once a day, and a 3 second fix for those that turn on Hey Siri. Any other problem is completely unrelated to this thread and shouldn't be lumped into the same area.
Hope that helps.
