Wrongs: Almost everything on iPad. It is so freaking slow, choppy, stuttery, laggy, buggy, and quirky on my mini 2, which for the record is the same as an iPad Air which is only A YEAR old. There is so much wasted screen, so much overdone translucency and poorly optimized software which drags the freaking thing down to hell. Things are usually executed pretty quick, but it's just the UI, how it all carries out. When I leave apps, very often it leaves as two big chops, however if I open the app again and immediately leave, it's smooth. The app has to be used for awhile to make this happen. I have to restart the iPad almost daily because rotating gradually gets slower and slower and slower. The battery life is pretty dang bad, and under the hood everything is just wrong. Ridiculous amount of crashing of stuff, CoreTime logs now with 8.2, backboardd, splashboardd, JetsamEvents, it is bad. Really really bad. The crash logs are an issue on iPhone as well, and again, battery life is pretty questionable. UI lag is present on iPad pretty much anywhere that involves a keyboard (ESPECIALLY A SPLIT KEYBOARD IN SAFARI), going into spotlight is pretty bad, sending medium to long messages in an already on-going conversation is stuttery, Siri animation still isn't great, everything stutters when you tap the URL bar, just no. I could go on much much longer but I was going to try and keep this decently succinct. I have already failed miserably at that. There's just so much that needs to be said about UI performance and bugs, particularly on iPad. It all is just SO sloppy. If iOS 9 isn't a huge bug fix update I will be extremely upset. It needs to be particularly focused on fixing glaring bugs and UI issues/PERFORMANCE ON IPAD first, then working out the things like nonstop crash logs, memory management, battery life, and the general sluggishness or random quirks.
