Consumer Reports gives thumbs up to iPhone 4S

The iPhone 4S "doesn't suffer the reception problem" of its older sibling, the iPhone 4, Consumer Reports said Tuesday, which has put Apple's phone back on its "recommended" list after more than a year of being off it because of the previous model's antenna woes.

"In special reception tests of the iPhone 4S that duplicated those we did on the iPhone 4, the newer phone did not display the same reception flaw, which involves a loss of signal strength when you touch a spot on the phone’s lower left side while you’re in an area with a weak signal," wrote Mike Gikas on the magazine's electronics blog.

Save 50% Of Your Smartphone's Battery Life With Wi-Fi Scaling

Researchers at the University of Michigan suggest that a reduction of the Wi-Fi clock during idle listening could give users more time with their phone.

Engineering professor Kang Shin and doctoral student Xinyu Zhang said that smartphones, including the iPhone, spend up to 80 percent of their power-saving mode in idle listening state, which checks the network for incoming data. However, they also found that this idle listening mode often consumes just as much power as when the phones are fully awake.
