- When I travel these days, I tend to look like a walking Radio Shack – cords bursting out of my pockets, bag overflowing with chargers and accessories. Partly, this is my own fault – as a tech writer, I carry around more gadgets than I strictly need. But most of the blame goes to the batteries in my iPhone and iPad, which run out so quickly that I'm forced to carry around not one, but two external battery packs to get me through a normal day of use.
Not a developer, so bear with me. To what extent are developers allowed to focus on power efficiency in the applications they develop? From what I can tell, there are so many other more pressing business considerations that power savings must get pushed pretty far down the list.
Depends on the type of app you are writing. Take a developer writing a game where he has control over all aspects of the app. He or She could take various steps to reduce energy intense operations such as using wifi, bluetooth, 3G etc. Keeping that to a minimum will help prolong battery life. But if you are writing a business app with little freedom to spend time on managing that stuff effectively then that can cause poor results. The ability to reduce power consumption is there but not everyone takes the time to do it. Take a look at this video for more info on it.
Please, you clearly have no idea how much computing phones do these days. Even just sending and receiving signals is incredibly complex, and power demanding. People work really hard to keep power usage down, don't demean their work with your nonsense.
Just mentioning a concept does nothing to argue for it.
