iOS 15.1 Beta 4 ― Bug Fixes, Changes, and Improvements

[sevenout]

Anyone else having an issue with their Apple Pencil lagging with iOS 15? Myself, my wife, and 2 other colleagues all have iPad Pros of various vintages (2 with FaceID and 2 with Home buttons) and we are all having the same problem. We are all running iOS 15.0.2 non-beta. We are all gymnastics judges and during a 2+ hour session of competition we use our iPads to document the routines as we are judging. We all use the app Noteshelf 2. Some time after starting the app and using it for quite a while (30-60 mins), the pencil will start to lag and sometimes not write. Closing the app and restarting it will make everything okay again for another 30-60 minutes. One of my colleagues updated her iPad from iOS 14.x to 15.0.2 after 1 day of competition and the next day she started having the same problem as the rest of us. So the problem only started for her AFTER she updated to iOS 15.0.2. For me, this has been an issue with 15.0, 15.0.1, and 15.0.2. I suppose this could be an issue with Noteshelf 2 as it does correct itself temporarily after restarting the app. Just curious if anyone else has noticed anything like this? I plan to install the iPadOS 15.1 beta and see if it continues.

Sounds like it's the app.

If you don't mind me asking, what activities were you doing? If simple web browsing either on the web or a social media app, was anything animating or moving? Either an ad or a video. The reason I ask is because if there was, it is not uncommon to see both more power draw(battery usage) and CPU usage to process a moving object.

I see it with my computer as well, everytime something is animated, and nowdays, sometimes in general, I will see my CPU and GPU usage go up due to processing. In every case, more power would be used and more heat would be produced. It does not matter if the device is mobile, or otherwise, they all do this.

Hope it helps

Most of the times it happens here on macrumors through Tapatalk while reading topics with a lot of replies. I guess the x is staring to show its age but strangely it was not the case during the summer beta testing. Some other social media and newspaper apps are also sometimes heating the phone up. I guess that is somehow related to iOS 15 because it does not happen all the time. Right now replying and can feel my iPhone X back heating up with this light task, and no background stuff running

There have been a large number of posts here about significant battery drain on Macrumors a while back, I believe that’s still going on. Anyway high battery drain would certainly heat a device up.

Yes, but since the pencil support comes from the OS and just updating iOS from 14 to 15 with everything else remaining the same causes the issue to appear. Yes, this could be an app compatibility with iOS 15 and probably is. However, there is still a chance this is has more lower level iOS issues. Since I don't use the pencil for anything other than note taking in that specific app I won't ever experience the issue any other way. This is why I asked my original question.
