Apple first need to fix iOS that's still more an OS designed for iPod with limitations. Was gifted the new 2017 Amazon Fire HD 10 which were selling for as low as $85 on Black Friday and not only is the hardware excellent with high end ARM A72 SoC but the Android OS is Linux based and doesn't have the limitations of iOS. I can manage all my Raspberry Pis and IoT devices via SSH and leave the app running in the background without it dying after 3 minutes like on iOS. Until iOS is fixed my iPads will continue to collect dust.
You can have this and awful battery life, I am happy to have an option that doesn't let tasks run constantly in the background and wipe the battery in a matter of hours while its just sitting there.
