Most of the people here have done the battery drain on set up and then recharge. The issue still rears it's head. So far it's looking like the only reliable method is to install the beta of iOS 9.2; although, many people are seeing success with other options. I think the other options like the hey Siri (which I don't have on), the cable swap (which I was the first to bring up, but can't seem to replicate the lockup anymore), the airplane mode, the restore fresh from iTunes are just all indicative of a software issue. Not sure if it's a cloud syncing issue, or a Siri indexing issue, or something to do with the new way that the screen doesn't refresh all the pixels, or what, but the only method that seems to have consistent hope is the 9.2 beta update, which means that we should hopefully see resolution to this with the release of iOS 9.2.
I had the lockup several days in a row when I first got my iPad pro, with apps running in the background, without apps running in the background. Everytime I had it lock up and did a force restart, the battery was at 100%. The lookups occurred only when I was charging to 100% and then letting it sit on the charger for several hours afterwards.
- Clean install of iOS 9.1, no iTunes restore, downloaded all apps from the App Store, logged into iCloud, Siri turned on, hey Siri turned off, night mode enabled for a 10 hour time period, mute off, 65 apps installed, default wallpaper changed, brightness at 75%.
- iPad pro 128 gold, lte, cellular not turned on, wifi turned on, using a 40Mbps internet connection. No keyboard attached, no cover, no case. All crashes occurred with the stock cable that came with the iPad. After a few days I swapped cables to a brand new one sent with my Apple TV 4 and have not experienced any lookups since. Even with the stock cable. (Which I've tried using to see if i can replicate the lock ups). I did swap my stock cable and charger to a dedicated outlet since my lookups stopped, so that may be part of it (all the lokups did occur with multiple 12W chargers plugged into a surge protector). Of course that may just be more rabbits being chased.
Hoping for a fix soon, not because I'm having the issues still, but because until a fix is released there is a cloud of uncertainty about the reliability of the iPad pro hanging in the air.
Also for the record, I use the iPad pro now pretty much exclusively anytime I'm away from my desk. Obviously there are apps on my desktop that I use, but I'm not a typical user, or even a typical business user: however, I definately can see Tim Cook's point that this could replace many people's laptops. If my relatives were looking to replace an old laptop, i would probably recommend the iPad pro. Outside of the lockup when charging to full, the actual use of the iPad pro is Wonderful. 80% of all computer users could honestly use this as their primary driver. Again, recognizing that the rest who are outside of that are probably special use cases or were computing and had to deal with high and low memory configurations on the command prompt from Bill Gates..
