IOS 11.2 drains battery
By Glen Coleman
This is the fastest update Apple has put out. Quite frankly it’s sloppy. My battery drains in a few hours if using it. Apple is not as good as it use to be. Should we start calling Apple Microsoft now?

Not surely yet

This book is not only poorly organized, but not only repetitively repeats very basic information, it seems deliberately short on the pocket computer’s (that’s everything but the phone) capabilities.
Like the pin-out for the only connector and specs for converting signals to usb.
It also seems light on how to create a more secure phone - then again, if Apple really wanted to build a secure phone, it would have started with shutters on the cameras (I mean sliding covers) and a switch disconnecting the mic when the phone is horizontal.
Add 4 stars if you don’t know what a transistor is.
I especially found the section on Do not disturb helpful.
