How long will 3GB last on a iPhone 4S on 4g?

How long will 3GB last on a iPhone 4S on 4g?

It depends on

++ how you use it, like browsing etc
++ if you have enabled any auto update of the apps then it will eat up
++ If you have enabled auto sync again it will eat up.
++ If you see any video streaming or music streaming then it will eat up quicker.

Normally, if you do the all the 3 above it should be fine and should last for a month ( if i believe that 3B data plain for a month )
But if you are using the 4th one, it will eat up more data, and if you are watching in HD eat up more…

  • Why do Iphone chargers (especially iphone 5) not last very long? I can never keep a charger more than a couple months without it breaking or ceasing functionality. It doesn't matter if I'm using the charger mostly in the office, in my car, at home, etc. Is this a scheme by manufacturers to keep charger revenue flowing or is this the universe's way of telling me I use my phone too much?
  • Is 3GB of Data Enough for 2 people on iPhones? Me and my brother are getting iphones. if we do 3GB of data, would that be enough for moth of us mixed together? also, i know about using Wi-Fi when its there, so of course i won't use the GB when there's Wi-Fi. also, is 3GB more than MB? And more than 1gb? Sorry i'm stupid… thanks:-) Its iphone 5 by the way

  • Is 3gb enough for IPhone 4 or 5? So I have the iPhone 4 and I have a 5gb plan right now and it's just to much money. So would 3gb be okay if: I use spotify a lot surf the web download apps? I would be using the Wi-Fi at home a lot and maybe sometimes using the phones Internet when I'm out and about. Would it work?
