I had an idea - since I'm really not "using" my Android S3 phone all day long, it gets frustrating when the bettery runs at 30% at 2pm, without any real use.
So the concept would be:
1) either a "ROM" of Android, which would be seriously minimal - like the device is not a smartphone - so only wake up on incoming call or text message
2) or an app, which does the same thing - suspends the phone completely, and wakes it up only on the incoming call or text message
I was just curious - does something like this exist? I don't care about apps, notifications, wifi or sync, I was thinking more along the lines of would it be possible to use your smartphone like a typical "cell phone", and when you need other apps or full features (GPS navigation with maps, or Shazam, or whatever it is you need) - you just "reboot" or do a qucik switch to "full Android" mode, and use those features.
Does any of this makes any sense?
I feel that the battery life should be at least 5 days in that mode, with light usage?
Anyway, I apologize if I got the wrong subsection of the forum, but I was just curious to see if anybody else already though of this, or if they didn't, would it be plausible? I'm a web developer, but I would maybe even try to make something like this in case there's a big need..
