There are certain messages making the rounds, claiming that entering #3307# on an iPhone will boost the network reception of the phone. Another variant of the same message says that entering this same USSD code will unlock a hidden reserve battery power in your Apple iPhone. An excerpt from the message goes like this:

By pressing #3307#, you’ll activate a special extra boost in your iPhone reception.

Another says:

Dialing #3307# will activate your phone’s “reserve battery power”. Battery life will increase by 50%. The reserve will automatically charge up the next time you change your device.

Does using #3307# Really Boost iPhone Reception or Battery Life?

Does dialing #3307# boost iPhone cell reception?

No; it does not. This USSD code does not trigger any function in your iPhone.

Does dialing #3307# code in your iPhone improve its battery life?

No; it does not. Dialing that code does not improve an iPhone’s battery life.

Both claims are hoaxes. Typing in or dialling this USSD code on your iPhone or other smartphone is not likely to do anything at all. I tried it on an iPhone 12 Pro Max and iPhone SE 2022, and it produced no such results.

Entering #3307# on your iPhone is as useful as singing, “London Bridge is falling down”. It won’t boost your cellphone signal, or battery, either. So where did this claim originate from? I have no idea. If you don’t believe me, though, you can type that code on your phone now. Zilch. Absolutely nothing.

Entering the code does not trigger any specific function or feature. This is because it is not a recognized or known USSD code. As such, nothing will happen when you enter it on your Apple iPhone.

Why do people think that entering this code on an iPhone does anything?

There are several reasons why people may think that entering #3307# on an iPhone does something. The number one reason is misinformation. There is a lot of misinformation on the internet about secret codes and hidden features for smartphones. Some websites or social media posts may claim that entering certain codes can unlock hidden features or perform specific actions, even if those claims are not true.

Some people may spread false information about secret codes or hidden features as a prank or hoax, just to see how many people will fall for it. Lastly, there is the element of confirmation bias. Confirmation bias is a tendency to interpret information in a way that confirms one’s preexisting beliefs or expectations. If someone believes that entering #3307# on their iPhone will do something, they may interpret any minor change or glitch on their phone as evidence that the code worked, even if it was just a coincidence.

It is very okay to be skeptical of any claims about secret codes or hidden features for smartphones, especially if they are not supported by credible sources or official documentation from the phone manufacturer. There are scores of such claims being passed round these days, especially via instant messaging services.
