Background Information and Research

Above is a complex diagram of how to charge your iPhone with fruit.

The internet says that there are many simpler ways to charge your iPhone, even one just as simple as plugging your iPhone into an apple. Now this is very hard to believe, but I will test all theories and separate myth from fact.

A similar diagram to what I am trying to accomplish is in an old science experiment in the 1800’s called the lemon battery by Alessandro Volta. It turns out that the acid in most fruits including lemons help create an electric flow that is shown in the diagram above.

If you put an iPhone charger in fruit with a lot of acid then it will charge the phone because of the zinc in the citrus.

If the above is true then a USB will charge the iPhone faster because it is a shorter path to the phone.

Parts of Experiment

1. Type of Design using to charge fruit

2. Time to charge up

3. Charger and iPhone 5s

4. Charging Factor

5. Same outlet, Same Charger, Same IPhone


· Apple IPhone 5s

· Apple iPhone 5 charger

· Pencil

· Paper

· Lemons, Apples, Oranges, Bananas

· 2 nails

· Hammer

· Timer


1. Different charging set ups (5)
2. Plug the charger into fruit and phone
3. See if charging icon pops up (if so start timing)
4. Record
5. Repeat steps 1-4 10 times for each set up

Observations and Data

Observations: Only designs with nails seemed to work: 2 fruits together with the nails


I observed that only the designs with nails worked and that the USB charged the iPhone faster in the designs with the nails and copper wire. The average time for the Wall Plug in was 73 seconds and the USB charged on an average 82 seconds. And the two tailed P value was 0.9125 which means that there was not a significant difference between the Wall plug in and the USB. The trend I observed was caused because of the nails and copper wire created an electricity flow and the fruit that were used were high in acid. It created an electric flow that was able to charge the phone. The USB charged it faster because it was a shorter path to the phone. It was a small difference between the wall and USB plug in, and that is shown in the small difference between the two.


My first hypothesis was highly supported because all fruits with high acid count ended up charging the phone. My second Hypothesis was also supported because the average for the USB was lower than the Wall Plug in. I observed that only the designs with nails worked and that the USB charged the iPhone faster in the designs with the nails and copper wire.


My experiment could be used in the wild if you have your phone and charger but no outlet. All you would have to was to find fruit. You can use the results by finding the best fruit to use with it (lemon). And use the USB instead of the Wall Plug-In because the USB chargers it faster.
