  1. According to a study by (PDF) Purdue University and Microsoft, free mobile applications aren't without a catch after all: you're paying for them in battery life. Abhinav Pathak and two of his…

    So they found out that applications that are heavy on constant processing and/or video graphics consume more power...

    Please... TELL ME MORE!

    PS: There are apps that limit the connection of other apps, if you would like to stop getting ads and things like that there are others like Adfree.

    I did read, thats the PS for. Still they dont make a comparison with the paid version of apps, that would have been cool.
  5. I think it's easy to understand that the paid versions would clearly use less power without having to see your location and download personalized ads or any ads for that matter. A comparison would be neat but I doubt it would tell us anything we couldn't logically predict.

    No, I think you <i>really</i> need to read again. Maybe even the source while you are at it.

    Also, apps such as Adfree do NOT block ads, they merely hide them; apps still consume unnecessary resources in the background.
  7. If the host is being blocked to prevent the ads from being dowloaded how can bandwidth still be wasted?

    I use Gemini to stop some apps from starting up when I boot up my phone, or just ones I find running when I never asked them to. When you go to configure an app running when you turn on your phone, you can sometimes see multiple triggers that "wake up" the app.

    I think in Android's case, it's too easy to get apps approved, and in turn, it's doing more harm than good. Google is Android's worst enemy IMO.

    just because you cant see doesn't mean it's not happening. Hope the double negative isnt too confusing, lol

    Uhm, the app tries to send a data connection somewhere, your phone denies it... so according to you the data is still going on and away and back? Yes the power usage of the app processing the request does happen, the connection doesnt.
  13. Don't make assumptions. Adfree works by blocking hosts in the system hosts file. Obviously not hiding ads but preventing them from being downloaded altogether.

    According to me..... I was stating a very general fact. Just because someone doesn't see something happen doesn't mean it's not happening. You take it however you want. :)

    All the android ad blockers do really, is prevent app hosts, and system hosts from downloading data after request.

    But here's the thing: they don't block the initiation of the request itself. What I mean is, they don't actually prevent the application from requesting the host, they only nullify the request after the fact. Third-party code can't modify other third-party code. There's a reason why ad blockers that don't require root access can't block ads from apps and games, but can block ads from the stock browser.

    Also, I'd like to point out I made a mistake; adfree does prevent data from being downloaded (it has been a while since I owned an Android, I admit). It is still futile, however, as whether it prevents ads from being downloaded or not, it still does nothing to reduce the resource consumption it takes an application to both gather information and then upload a request that will, inevitably, be nullified by adfree or any of the remaining true ad blockers.
