apple pencil battery life

I'm posting a screen shot from my iPad to demonstrate a problem with touches delivered by the Apple Pencil. In the demo app, I stroke the pencil across the glass left to right. Each touch is drawn with a black dot, each coalesced touch is drawn with a red dot. For each touch I draw three data as whiskers perpendicular to the direction of motion. The green whisker represents the elapsed time since the last touch. The orange whisker represents the distance traveled since the last touch but magnified so that it's easier to see. The purple whisker is the velocity, that is, the orange whisker divided by the green whisker. On my 240Hz iPad Pro, the delta time should be a constant 4.166... milliseconds. Instead I get some 4 millisecond intervals, some 3 millisecond and some 5 millisecond. Look at the green whiskers. The smoking gun here is that the time intervals are EXACT integral millisecond values. (I see this in a log file that I'm not including here.) Someone someplace is rounding the

As a digital artist from China who creates concept art for large gaming companies, I absolutely love using the iPad Pro and Apple Pencil. I rely on them for long hours each day to complete my work. Apple Pencil's design is truly innovative, and I am eager to praise its developers. They are undoubtedly geniuses, and I have always appreciated Apple's intuitive design that feels natural and instinctual to use. However, there are two missing features that are crucial to artists and users alike. I find it surprising that these features have not yet been implemented by Apple or any third-party tools. Therefore, I am reaching out to the developers themselves for help in bringing these essential features to Apple Pencil users. The first feature is the inability to customize the location of the pencil's point of contact. I hope that a system-level setting can be added to allow for micro-adjustments of the stylus's nose position.

Build the ability to airdrop or “Apple pay” type of technology but to share battery life. Use case: I was recently at a sporting event with my daughter and needed to leave her there and I didn’t have a charger to give her. Her phone was at 11% and mine at 76% I wish I couldn’t texted her some of my battery power or tapped my phone to hers and approve a battery life transfer. Sending this thought to others who would know better how to make that a reality.
