iPhone 2.2.1 Wi-Fi failures linked to battery heat

A number of iPhone users are reporting intermittent problems with Wi-Fi after installing iPhone OS 2.2.1, which have since been linked to a battery issue by one intrepid user. According to an Apple Discussions thread, affected units randomly drop Wi-Fi signals, refusing to reconnect to any network for a period of time. Originally, many of the users believed the problem to be heat-related, as some users reported success after putting their phone in the refrigerator or freezer—a process we would warn against, as it could result in water damage or a water damage indicator being triggered from condensation, thus voiding any remaining warranty.

Scottish user ScottieWil physically opened his iPhone, discovering that Wi-Fi immediately returned when the relevant chip was touched with a Nitrogen stick to quickly cool it down. Upon further inspection, however, he found that the issue appears to be directly linked to the percentage of battery charge—his Wi-Fi seemed to work consistently no matter what the temperature as long as the battery charge was less than 50%—and suggested that the battery is “very sensitive to temperature,” which would explain why the freezer trick worked for a short period. Despite ScottieWil’s efforts, there appears to be no immediate fix for the issue. One user wrote that an Apple representative made an appointment for him to get a replacement phone without 2.2.1 installed, suggesting Apple is aware of the problem, if currently unable to provide a solution.

Great, that e-mail I just got from at&t;saying that if I upgrade to 2.2.1 my battery life would increase really meant to say that I’ll get longer usage because my Wi-Fi won’t work.  Typical…

I recently had my iPhone replaced for the same reason. My battery life was abysmal, and heat was an issue. Apple support did NOT acknowledge the problem above, but instead replaced the phone. My knew one has similar issues, with battery life being as little as 3 hours on a single charge. Apple needs to fix this bug ASAP.

I had the same problem few days ago just after updating to FW 2.2.1. I did everything possible to have Wi-Fi and Bluetooth back but all with no use. My speculation is that Apple did this in purpose so people will have to use their 2 and 3G to connect to Internet instead of the Wi-Fi, I?m saying this because the problem has been there for 5 months now and Apple has not released a single statement to address the issue. I really hate being trapped by such unethical behaviour.
