Google doesn't make better phones, they were just less hostile to the consumer. That seems to be going away :(
Leaving Google for Apple, and expecting a more open app store, is going to be disappointing. I’m not a Google fanboy by any means, just pointing out the landscape out there
It's not about 'saving battery' its about preventing undervoltage that janks everything up.
Having dealt with more than one windows phone that didn't have this feature or had it in a bad way (i.e. 520/521 would just 'reboot', 640 and 950XL would just kill an app) I wish Microsoft would have figured that crap out lol.
