Lab tests: Why Consumer Reports can't recommend the iPhone 4

Lab test: Apple iPhone 4 design defect confirmed

It's official. Consumer Reports' engineers have just completed testing the iPhone 4, and have confirmed that there is a problem with its reception. When your finger or hand touches a spot on the phone's lower left side—an easy thing, especially for lefties—the signal can significantly degrade enough to cause you to lose your connection altogether if you're in an area with a weak signal. Due to this problem, we can't recommend the iPhone 4.

We reached this conclusion after testing all three of our iPhone 4s (purchased at three separate retailers in the New York area) in the controlled environment of CU's radio frequency (RF) isolation chamber. In this room, which is impervious to outside radio signals, our test engineers connected the phones to our base-station emulator, a device that simulates carrier cell towers (see video: IPhone 4 Design Defect Confirmed). We also tested several other AT&T phones the same way, including the iPhone 3G S and the Palm Pre. None of those phones had the signal-loss problems of the iPhone 4.

Our findings call into question the recent claim by Apple that the iPhone 4's signal-strength issues were largely an optical illusion caused by faulty software that "mistakenly displays 2 more bars than it should for a given signal strength."

The tests also indicate that AT&T's network might not be the primary suspect in the iPhone 4's much-reported signal woes.

One solution to the Apple iPhone 4's antenna
problem is to cover the lower left corner with tape.

We did, however, find an affordable solution for suffering iPhone 4 users: Cover the antenna gap with a piece of duct tape or another thick, non-conductive material. It may not be pretty, but it works. We also expect that using a case would remedy the problem. We'll test a few cases this week and report back.

The signal problem is the reason that we did not cite the iPhone 4 as a "recommended" model, even though its score in our other tests placed it atop the latest Ratings of smart phones that were released today.

The iPhone scored high, in part because it sports the sharpest display and best video camera we've seen on any phone, and even outshines its high-scoring predecessors with improved battery life and such new features as a front-facing camera for video chats and a built-in gyroscope that turns the phone into a super-responsive game controller. But Apple needs to come up with a permanent—and free—fix for the antenna problem before we can recommend the iPhone 4. 

[UPDATE: Some commentary suggests we've retracted an earlier recommendation of the iPhone 4. In fact, our first blog on the iPhone 4's performance, and a followup comparing it to the Motorola Droid X, were based on preliminary testing, as we stated. Those earlier tests did not address antenna performance. We recommend products only after all tests are complete, and as part of our full smart phone Ratings. —Paul Reynolds]

If you want an iPhone that works well without a masking-tape fix, we continue to recommend an older model, the 3G S. (The full list of recommended smart phones models appears as part of our latest Ratings, available to subscribers.)

결국..수신문제만 해결되면.최강의 폰이되는건가..^^; 그럼 난 아이폰 4S ㅎㅎ 지금은 3GS ㅋ

[알리시아]

그래도 스마트폰중에는 아이폰이 끌리더라. -ㅅ-ㅋㅋ

[밀크티~♡]

폰 고장 나면 안조치않을까용? 히힛~~

[개념강제주입사]

그래도 아이폰이죠. 갤럭시따위는 흉내낼 수 없는 위엄이 있음... 공짜로 준대로 갤럭시 따위는 안씁니다. ㅋㅋ 더 좋다고 해도 안써요~ 쿠헐헐헐~~~

[수퍼마리오]

공짜로 준다면... 저는 씁니다. ㅋㅋㅋ

[조신한깡반장~^^V]

갤러시 S2는 끌리더군요..소문대로 출시된다면..^^ ㅎ
