Here's how much the iPhone 5S and iPhone 5C battery autonomy will increase compared to the iPhone 5

  One of the great novelties of iPhone 5S si iPhone 5C is represented by the implementation of a larger capacity battery, a rumor suggesting that Apple Lossless Audio CODEC (ALAC), would have implemented a 1600 mAh battery instead of the 1440 mAh one, present in iPhone 5. It is not known whether this modification or the new M7 chip they improve autonomy, but it is clear that users will have more time to use the new terminals. More precisely, we are talking about a 25% increase in the time spent talking on the phone on a 3G network and the time spent surfing the Internet using a connection LTE 4G.

  Apart from these, the standby time of the new terminals will increase by 11%, and that's about all the improvements in terms of battery autonomy. Unfortunately, we will still have 8 hours of usage for surfing the Internet using a 3G network and 10 hours of surfing the Internet using a Wi-Fi network, but maybe you will use the 4G LTE networks more often. Even if Apple only specifies these standard usage times, autonomy should increase no matter how you use the terminals, even if you don't use them a lot for browsing and talking on the phone.
