where can I get an extended battery and juice defender for iPhone 4S? and how long will the battery last?
There are a few different options for extended battery cases. As far as how long will they last; there's too many variable for anyone to really answer that. Signal, Settings, usage, apps, connections are all things that can impact the battery and for each person they are typically different. Check the
TiPB store they have a few options for extended batteries.
Regarding Juice Defender - I'm not sure. I've looked at if for my Android devices but I don't like the idea or turning things off. I'd rather just use my phone and keep a charger handy.
