Anandtech was able to offer a detailed analysis of the potential problems iPhone 4 signal from the antenna. Their analysis can light on the experiences of people with the iPhone in April and a decrease of the signal when the camera is hand held spilled.

The question has generated much press since the iPhone launch in April due to a variety of reports from users about the subject. Apple has maintained a degree of signal loss is normal when mobile phones are held in the hand. In a memo leak Support has also stressed that the performance of antenna 4 iPhone 3G is better than the iPhone. Anandtech Based on the analysis, it seems Apple is correct in that statement, but with some reservations.

iPhone 4 Signal Strength Returns

At first, Anandtech could hack together a way for four iPhone Signal Strength real relationship instead of the usual 5 level signal strength bar. How many bars in this order of magnitude of 5, a bad representation of the actual signal strength is noted. As shown, are almost 40% of the range of possible levels reported as five bars. Because of this bandwidth, it could be a big difference in the actual signal strength, even if the same “5 Bars” is displayed.

He conducted several tests comparing the signal loss of the conclusion of the iPhone four hands in different positions:

Accordingly, the iPhone has a significantly greater decrease in the level 4 in all positions, compared to the iPhone 3G, which preceded it. Perhaps the most striking difference in the position “of course holding, which could theoretically” bottom out “a signal of 4 bar or reduce the bottom of the five bars signal on a bar. Holding 4 iPhone, of course, exacerbated the problem. All phones are not the same behavior, even when the external antenna 4 probably overstates iPhone is the effect.

However, Anandtech says its tests have shown that the iPhone antenna is actually improved in four 3G – the addition of the validity of previous statements by Apple. In their investigations, Anandtech found that the signal strength is very low (up to -113), 4 Place calls iPhone a lot better than the iPhone 3G.

It really is amazing the difference in the sensitivity of the iPhone has seen four in comparison to 3G, and questions to hold the phone on the one hand, the reception has improved absolutely clear. I felt that I had not taken the iPhone ever been. There is no doubt in my mind the iPhone is the best cell is occupied, but even though the measured signal is less than the 3G.

Overall, the results could help explain some apparently contradictory statements and observations. While the iPhone in April, a better performance in the same level as the iPhone 3G, iPhone, 4th May may have signal can be greatly reduced through a reduction in the same position. This could explain all represented, but the most extreme cases. Finally, Anandtech also proposes the use of a case can be better, and moving with a case of collision, the iPhone four damping properties than other smartphones.
