The differences in terms of battery capacity in the iPhone 4S and iPhone 5 terminals are very small in favor of the latter, but in terms of battery autonomy those from Which? I maintain that the Apple company's terminal is doing poorly. According to a test carried out by them, the iPhone 5 would last only 3 hours and 20 minutes in internet browsing tests using a 3G connection, the iPhone 4S having an autonomy of only 8 minutes longer. Apple says that the iPhone 5 works for 8 hours while surfing the Internet using a 3G connection, in my experience the autonomy was much higher than 3 hours and 20 minutes, but this test does not say this.
The test still says that the Samsung Galaxy S III works for 6 hours under the same conditions, so we are talking about almost double the autonomy, and that is more than strange. If you have an iPhone 5 you can try the same thing and I think the results will be much better than those obtained in this test, at least that's how it is in my case.
