Apple's newest smart phone performed very well in CR tests, and while it closely resembles the iPhone 4 in appearance, it doesn't suffer the reception problem found in its predecessor in special tests in CR labs.
The Apple iPhone 4S also did very well in standard tests of battery life; like the iPhone 4, it scores Very Good overall on that attribute. And the iPhone 4S and new samples of the iPhone 4 have displayed no notable battery problems in additional special tests, even after some owners complained on user forums of short run times with some samples of both phones.
Overall, the new iPhone 4S scores higher in the Ratings than the iPhone 4, thanks to such enhancements as an upgraded camera, a faster "dual-core" processor, and the addition of the intriguing Siri voice-activated feature, which accepts and responds to verbal commands in a conversational manner, using a synthetic-sounding female voice.
