Re: Bad Battery
Really in that case they'd be better trying to sell and get a phone with a better battery really. You should never have to make a smart device less smart to make it save battery. What's the point in any of the features then? I'm really considering getting rid of mine at this stage.
The key to maximizing battery life is finding the stuff you *don't* want or need and trying to get rid of it as well as you're able (becauser we know that most of that stuff can't just be uninstalled).
It isn't about making a smartphone dumb, it's about disabling features I neither use nor care about. While that list of apps and features will differ from person to person, we all have one. Even if you never disable a thing that's activated on your phone out of the box, you still have stuff you just never use.
Sometimes I do choose function over battery savings. An example is my choice to use the Chrome browser (Chrome Dev actually). I like it's integration with my desktop version of the browser, and so I use that instead of something that would likely save me a bit of juice.
On the other hand, with something like the Facebook app, a notorious resources hog for its entire existence, I save the resources and use the mobile browser to visit FB when I want to do that.
Stuff I don't need at all, I uninstall, disable, or force stop with Greenify (at the moment...jury still out for me on whether Greenify is *really* all that).
Anyway, people can improve battery life without suffering.
