iOS corebluetooth:Delegate method know weather peripheral connection is out of range and inside of range

Question

I am working on the corebluetooth framework in iOS. My central connection is iPhone and I have to connect to peripheral device.

1) Are we able to find whether peripheral device is inside or out of range ?

2) How much data can be received or sent through bluetooth app?

3) We should give The service uuid's and characteristic uuid's at first time itself or these info will be get after discovering by central device?

4) Can we able to know the battery status of peripheral device? if so there is any delegate method present in framework itself

Thanks In Advance
