I would very much prefer an easy way to go 'off the grid' - one button to disable all the shit that is draining your battery. 3G, data, location services, Wi-Fi.

Jailbreak used to help on iPhone and they did introduce the swipe bar to disable Wi-Fi, but put so many more obstacles to disable the rest.

Disabling location services will now prompt you whether you are sure you want to disable AFTER A FUCKING DELAY.

I would like very much that Google Maps wouldn't point me in a middle of ocean when my location services are disabled and I just want to peek at a map, not to find out where is some badly SEO'd shop.

But most of all, I would like apps to keep the data I opened 5 minutes ago. I just hate when you are in the tube, had your route planned and suddenly all the info is gone. Or the comment you wrote on HN and switched a tab is gone after refresh. Apple, PUT SOME FUCKING RAM ON YOUR IOS DEVICES.
