Apple releases iOS 15.7.1 for users who can't, or won't update to iOS 16
baconstang said:I'm still looking for a good reason to update from iOS 14.
Maybe 17?
To improve your experience I would highly recommend updating your phone to the latest iOS version.I can understand why you don’t want to upgrade your PC to Windows 11, but here on macOS or iOS, the upgrades are free and relevant: just go for it! -

Apple Watch Ultra has exposed screws, but still a difficult repair
Please AppleInsider, check your maths! If the battery on the Series 8 is 1.19Wh and the Ultra has 2.1Wh it is an increase of (2.1-1.19)/1.19 hence 76%! Not 60% 😉 However, the Series 8 is 60% smaller than the Ultra (because then you do (2.1-1.19)/2.1. Basic maths.
If you are not convinced, imagine a Series 9 that is 1.5Wh and a new Ultra that is 3Wh, then without calculating you know the new Ultra is 100% bigger than the Series 9, and you calculate it that way: (3-1.5)/1.5=100% whereas the Series 9 is (3-1.5)/3=50% smaller than the new Ultra.
Hope that was clear ☺️ -
iPad Pro with OLED may be more expensive because of dry etching

Well I doI’ve been a DRIE (Deep Reactive Ion Etching) process engineer for more than 10 years before changing completely my career and become an iOS developer. So I can tell you how amazed I was about reading about my field in this article where most of it is actually correct. An error is the sentence “While dry etching isn't strictly new, it's not used in much at present.” You would not have accelerometers or gyroscopes or sensitive pressure sensors without MEMS produced with DRIE (a sort of dry etching). Hence no Nintendo Switch, no funny games on the iPhone or IPad and so on. So what a mistake to say that dry etching is not used so much these days. The patent at the origin of it is called the Bosch process and it is from the 90’s! Airbags in cars have existed for decades thanks to dry etching!
And if you play again one of the keynotes where Apple was presenting Deep Trench Isolation (DTI) in order to avoid having pixels bleed into another it is using dry etching. So all of you are using components made with dry etching in the gadget you are currently holding 😃.
If you have questions about dry etching or working in a clean room making MEMS, just ask me, I’d be happy to explain.
More articles like this! Thanks 🙏
PS: I’ve worked for Applied Materials Inc and have several patents on the design of DRIE chambers for MEMS. -
