Is the iPhone 4s iOS 7 good on battery as of now?

I better advice you to not to update your ios as it will load your device and it consume more power and it will also start hang and the device will become slow so you will not satisfy with ios 7 in your iphone 4s.

And you are asking this why? Of course it is!
