Apple how much water

iPhone 12 water test: How deep can Apple’s phone really go?

We dunked Apple’s iPhone 12 in the chilly, deep waters of Lake Tahoe to find out what would happen.

Apple’s iPhone 12 is water-resistant, so it should be totally fine if you accidentally drop it in the pool or it gets splashed with liquid. The iPhone 12’s IP68 rating means it can survive up to 19.6 feet (six meters) of water for 30 minutes. But how deep can you really take this phone? We took a brand-new iPhone 12 for a swim in the frigid fresh water of Lake Tahoe, California, to find out. Turns out that like its predecessor , Apple’s newest iPhone can handle a great deal more than its official rating.

To test out the water resistance, we teamed up with Mission Robotics to mount our iPhone 12 on the company’s underwater drone, Theseus. The drone can go as deep as 984 feet (300 meters) underwater; the pilot can see the view from Theseus’ camera, as well as monitoring depth and water temperature metrics from a computer on shore.

Although we only tested the regular iPhone 12, Apple’s IP68 water resistance rating applies to all four iPhone 12 models: the iPhone 12, iPhone 12 Mini, iPhone 12 Pro and iPhone 12 Pro Max. Watch the video on this page for the full test and to see some amazing underwater footage from the drone.

Dive 1: Testing the claim (19.6 feet for 30 minutes)

According to Apple’s support page, you shouldn’t intentionally submerge or swim with your iPhone, or take it to extreme temperatures. But for the purposes of our test, we wanted to push it to the limits.

For our first dive, we wanted to test the IP68 claim: 19.6 feet (6 meters) of water for 30 minutes. From the shore of Lake Tahoe, we positioned the iPhone on a mount facing the drone’s camera with the screen set to stay on, so we could see if anything happened to the iPhone while it was underwater.

The water temperature in Lake Tahoe at this depth was 52 degrees Fahrenheit (11 degrees Celsius).

Once the 30 minutes were up, we pulled the phone out of the water and dried it off with a cloth. Then we tested it out to see if the phone was working. The touchscreen was fine and the volume rocker worked as expected. All three cameras (front, ultrawide and wide) looked clear with no evidence of fogging and the photos looked normal. We recorded a voice memo before dunking the phone and could hear that the speaker sounded a little muffled in comparison after the first dive, but it’s hard to tell whether that would’ve improved after letting it dry out longer. Apple’s support page suggests placing the iPhone’s base and Lightning connector in front of a fan to help the drying process. We had other ideas, however.

Dive 2: The extreme test (65 feet)

With the iPhone 12 working as normal, we got the drone ready for its second dive in Lake Tahoe. This time, we wanted to take the phone to more extreme depths. We submerged the phone to 65 feet (20 meters) underwater, more than three times the maximum depth rating. The water temperature at this depth was 50 degrees Fahrenheit (10 degrees Celsius).

With the timer running on the iPhone 12’s screen, we could see how much time had elapsed since we submerged the phone. Once it hit 30 minutes, we decided to leave it submerged a little longer just to see what would happen. We finally pulled the drone out of the water at the 40-minute mark and ran through the same tests again.

Surprisingly, everything worked as normal. The screen was responsive, the volume and power buttons worked, and the two cameras were in working order as well. The speaker still sounded muffled when playing back the voice memo, but it was still audible.

After wiping down the iPhone 12, we powered it down and let it sit for a few days to let it dry out completely.

The final test

After letting it dry out for 72 hours, we wanted to do one final test to see if there had been any long-term damage as a result of the extreme underwater test. The phone itself was completely dry, but its three lenses — the ultrawide and wide-angle on the back, as well as the front camera — had developed some fogging.

At this point the battery had also completely drained, so we let the phone juice up for a while via the Lightning port before powering it back on. But once we did, the iPhone 12’s screen showed a Diagnostics prompt. After trying to get through the Diagnostics prompt a few times, we plugged the iPhone 12 into a MacBook to see if we could reset the device. It worked, but we still couldn’t get past the Diagnostics screens.

While we have no way of knowing exactly what caused this error to happen, it may have been lingering water damage, the shift in temperature between the cold water of Lake Tahoe to an indoor environment, or a combination of both. To see how the iPhone 12 fared a few weeks after submerging it in the lake, watch the video where we crack it open below.

How Much Water Is In an Apple

Apple-themed activities don’t have to be limited to art projects for younger children. There are a number of apple-themed science activities that you can do with older children, too. By questioning how much water is in an apple, older kids can learn many science skills and use their reasoning powers.

How Much Water Is in An Apple

Apples, like many other fruits, have high water content. The following experiment can help your child not only visualize, but also measure, exactly how much water is in an apple.

Goal of the Activity

To create hypotheses and participate in a science experiment to answer the question «How much water is in an apple?»

Skills Targeted

Scientific reasoning, scientific method, following an experimental protocol.

Materials Needed

• A food scale or postal scale
• Apple
• Knife
• Elastic band or a piece of string
• Apple dehydration log: A sheet of paper or computer spreadsheet with lines for each apple segment, its initial weight, and its weight after two days, four days, six days, etc.

Procedure

1. Start the activity by talking about what your child knows about the taste of apples. Different varieties have different flavors, but what do they have in common? One observation may be that they are all juicy.
2. Cut the apple into quarters or eighths and remove the seeds.
3. Weigh each of the apple pieces on the food scale and note the weight on the apple dehydration log, along with a hypothesis of what is going to happen as the pieces of apple are left open to the air.
4. Wrap an elastic band around the apple pieces or tie a piece of string around them. Then, find a place to hang them up to dry out. Note: Putting the apple on a paper plate or paper towel won’t let apple slices dry out evenly.
5. Weigh the apple pieces again in two days, note the weight in the log and rehang to keep drying.
6. Continue weighing the apple every other day for the rest of the week or until the weight no longer changes.
7. Add the beginning weights for all the apple pieces together. Then add the final weights together. Subtract the final weight from the beginning weight. Ask: What’s the difference? How many ounces of the apple weight was water?
8. Ask your child to write that information on the apple dehydration sheet to answer the question: How much water is in an apple?

Apple Tree Irrigation – How To Water An Apple Tree In The Landscape

Apple trees are great for backyard orchards, providing fruit year after year, a crisp and sweet fall treat. But, if you don’t understand how to care for your trees, you may lose that fruit. Watering apple trees is usually not needed after the first year, but until they are at that established point, irrigation is a crucial element of care.

How Much Water Do Apple Trees Need?

Apple tree water requirements depend on rainfall. In general, for an established tree, you won’t need to water it unless you are not getting much rain or there is a particularly dry spell or even drought. About an inch (2.5 cm.) or so of rainfall every week to ten days is adequate for most apple trees. Trees in their first growing season may need a little more than this.

How to Water an Apple Tree

When you do need to water your tree, it is important to do so without creating standing water and soggy roots. This can be as damaging as drought conditions for your tree. Too much water depletes oxygen from the soil, prevents the roots from absorbing necessary minerals, and makes a tree susceptible to rot and infections.

Ideal apple tree irrigation involves giving the roots a deep soaking. Let a garden hose trickle around the base of the tree for an extended period of time. This will give the soil time to soak up the water and minimize runoff. A soaker hose can do multiple trees at one time. Each time you water, make sure the ground around the tree and roots gets fully soaked.

Knowing how much water to give your apple tree will depend on factors unique to your climate, weather, and soil. If you see standing water, you may be overwatering. If the weather is unusually hot or dry, you may need to increase watering for that period of time. Waterlogged roots are always worse than dry roots, so always err on the side of caution when watering apple trees.

How much water do Apple’s thirsty online services need?

As Apple’s online services expand, how much water is it using at its data centers?

How thirsty is your Apple Music collection? How much water gets used up when you send an email through iCloud? Not a great deal, but the truth is the data centers that drive services like these are incredibly thirsty creatures.

Drop by drop

Every online photo, all those Apple Maps requests, Siri interrogations, FaceTime chats, Apps downloads and iMessage exchanges all use drops of water.

Apple used 160 million gallons of water across its data centers last year. (It used a total 573 million gallons (2.1 billion litres) of water across its entire US business).

The amount of water being used to drive online services is vast. US data centers consumed 626 billion liters of water in 2014, according to the US Geological Survey.

This includes both the water used to cool the servers and the water used to generate the electricity powering them. (Apple data centers have been 100 percent renewable since 2013).

A grain of rice

To put these figures into some kind of context, it takes around 5,000 litres of water to produce 1 kilo or rice, which means US data centers could be estimated as using as much water as it would take to produce a year’s supply of rice for just under a million Americans.

Data centers aren’t the biggest water consumers.

Agriculture accounts for around 70 percent of all fresh water use, though 60 percent of that use is wasted.

Water is also linked to electricity generation, which accounted for about 17 percent of water used in California in 2010.

The big four

Apple owns four data centers that support “the vast majority” of its online services in Maiden, North Carolina; Newark, California; Reno, Nevada; and Prineville, Oregon.

Apple’s most recent Environmental Responsibility Report shows it recognizes it has a water addiction. As noted by Data Center Knowledge, the company states:

“The profile of water use at our data centers, corporate offices, manufacturing sites, and retail stores differs significantly depending on the climate and nature of activities. We have begun to map those operations against indicators of water risk, which include water scarcity, business risk, and habitat and livelihood impact to the basins in which we operate. This analysis will help prioritize our conservation efforts across our operations.”

Apple has big plans for services, which it couples with a sense of corporate responsibility as evidenced in its annual environmental reports.

“We’re constantly working to minimize our water use, so we monitor it within our cooling, landscaping, and sanitation processes and at our manufacturing sites. Then we develop targeted ways to reduce it. That includes creating cooling systems in our data centers that can reuse water up to 35 times.”

Don’t waste water

Apple recently announced a new water conservation attempt. It is paying for a water treatment facility to recycle water from Prineville, Oregon’s regular sewage treatment system for use cooling its huge data center there. The biggest water consumer in the city, Apple used 27 million gallons of the fluid to cool its data center there last year. «We are proud to partner with Crook County and the City of Prineville on this effort, and are committed to doing our part to preserve natural resources,” Apple told Wateronline.

“By recycling water for Apple instead of taking it straight from the tap, the city says its new facility will save nearly 5 million gallons a year,” The Oregonian reported.

The company needs to be committed to water preservation. Apple already has one large data center in Prineville, is building a second, and last month proposed building a third. As it expands its services offering, you can imagine its water consumption will also increase. What’s reassuring is the effort the company puts into minimizing its water addiction. It’s an attempt that should be matched by any other online service provider.
