IPhone 12 water permeability: can you shoot underwater? Test

by


According to Apple, the new flagships of the company, the iPhone 12 and iPhone 12 Pro, are capable of withstanding a half-hour immersion in water to a depth of 6 meters. Of course, there were people willing to check it out.

♥ BY TOPIC: How to wake up your iPhone screen: five ways.

During the practical test, the manufacturer’s direct statement about the possibility of the smartphone staying at the same depth of 6 meters for 30 minutes was checked, and the second test turned out to be more extreme. It was decided to test the moisture protection capabilities of the iPhone 12 at a depth of 20 meters. And this is how it all happened.

iPhone 12 was placed on the shores of Lake Tahoe on a special mount opposite the camera of an underwater drone. The smartphone screen was turned on to see what was happening with the phone during its stay in the lake.

After immersion for half an hour in water with a temperature of 11 degrees to a depth of 6 meters iPhone 12 continued to work normally… But the sound of the speaker began to seem a little muffled relative to those indicators that were before the test. But most importantly, elements like the touchscreen, cameras, and keys still worked.

In the second test, the iPhone 12 was submerged in water at a temperature of 10 degrees to a depth of 20 meters. The smartphone stayed there for 40 minutes. Surprisingly, all functions worked as before. The screen remained responsive, the volume and power buttons also worked, and the cameras remained operational. The speaker still sounded muffled during playback, but was still audible.

It was only after 72 hours of drying that traces of fogging appeared under the back and front cameras. The iPhone 12 ended up displaying a diagnostic prompt. There was no way to get rid of this notification. Even restoring (flashing) the device did not help.

Yes, this test can hardly be called scientific. However, it is clear that the iPhone 12 is capable of withstanding deep diving and clearly meets the IP68 standards. But, like all electronics, there is a limit on the amount of water that can get inside.

Don’t deliberately dip your phone into water, whether it’s a bathroom or a lake. In addition, Apple warns that any damage to iPhone caused by contact with liquid will void the company’s warranty.

We suggest watching the full video of this test below.

Tell us in the comments if you had any incidents of your iPhone 12 or older models in the water and how it ended.

Spatial audio in AirPods: how to turn on and check the sound (+ audio test)

by


At its summer WWDC 2020 presentation, Apple put a special emphasis on the new announced features of the AirPods Pro wireless headphones, of which Spatial Audio was the most intriguing. This software development should provide users with the ability to watch videos and listen to music with a realistic immersion effect without special equipment.

♥ BY TOPIC: 20 iPhone features that can be disabled for most users

What is Spatial Audio in AirPods Pro?

The developers themselves compare the user experience when listening to audio content in surround sound mode with going to the cinema – surround sound comes from all directions at the same time and changes with every movement of the user’s head relative to the parent device (iPhone, iPad, Apple TV, etc.). And this is a really useful feature, giving you new sensations that are easily distinguishable from conventional stereo and even 5.1 surround sound.

How does Spatial Audio work in AirPods?

To create this effect, Apple uses special software technologies that use the device’s accelerometer and gyroscope to create a kind of sound field, inside which the user’s head and gadget are located. This creates the feeling that instead of two headphones (as in ordinary stereo mode), the listener receives waves from a multitude of virtual sources placed around them, as a result of which even watching a movie on a smartphone can become a powerful alternative to going to the cinema.

What devices support Spatial Audio?

The feature is only available to owners of top-end AirPods Pro, and support is also expected for AirPods Studio, which may launch in the fall of 2020.

Spatial Audio requires iOS 14 or iPadOS 14 or later. In addition, the AirPods Pro themselves must be updated to the latest firmware. Please note that AirPods Pro firmware updates automatically while charging.

Naturally, not every video on YouTube or a movie downloaded from the CAMRip torrent can be watched in surround sound, this requires content with 1.5 or 1.7 surround sound, as well as Dolby Atmos.

The Spatial Audio feature in AirPods Pro was not in vain that it was separately noted as part of the June WWDC announcement and will certainly not only be massively used by Apple headphone owners, but also encourage content creators to record surround sound in appropriate formats. Thus, spatial audio can be added to the list of reasons to upgrade to a new version of iOS for those who have not yet done so.

Test ping of any site or computer: how to check on Windows and Mac?

by


If you communicate with IT experts or inveterate gamers, you probably heard the word “ping”. Computers and websites “ping” in order to check the connection speed, find out the network status of another PC or site, or fix problems with Internet access. But how do you know the “ping” yourself? Now we will tell.

What is Ping?

Ping is a program for checking the integrity and quality of Internet connections in TCP / IP networks. In everyday life, the request itself was also called “ping.”

♥ BY TOPIC: We translate megabytes into megabytes, or how to correctly understand the speed of the Internet.

What program is needed to test Ping?

Checking ping is only at first glance a difficult event. In fact, in order to find out this parameter, you don’t need to be a cunning hacker or an experienced programmer at all.

On all popular operating systems – Windows, Mac, and Linux – the ping measurement is run through the command line. On Windows, it is called that; on Mac and Linux, the Terminal application is used.

The easiest way to open a command line or Terminal is to use the built-in search in the OS.

Once the command line or Terminal is started, enter the command to start the ping measurement:

ping [адрес веб-сайта]
or
ping [конкретный IP-адрес]

example: ping yablyk.com

Test ping of any website or computer

On Windows, the default ping is only taken once. To do it constantly, enter a command like ping -t [адрес веб-сайта или конкретный IP-адрес]. On Mac and Linux, the query repeats automatically; you don’t need to do anything.

♥ BY TOPIC: Wi-Fi speed: how to check on a computer, iPhone or iPad and how to avoid errors.

What do ping request results mean?

Four variables deserve attention:

  • Time: how much it took to send and receive ping. Up to 20 milliseconds is a very good indicator, more than 150 is a bad result, there will be noticeable delays in online games;
  • TTL: the number of networks through which ping passed;
  • Packages: the number of packets sent and sent must be identical;
  • Round-Trip Time: minimum, maximum and average time spent on ping. Too much difference between the three numbers indicates that the network is unstable.

♥ BY TOPIC: Speed ​​test, or how to check Internet speed on iPhone, iPad and any computer: 5 best services.

5 useful tips for measuring ping correctly

1. Repeat the test several times. It often happens that the speed of your Internet connection jumps up and down. Therefore, an “honest” result is given only by many multiple checks.

2. Do not measure exclusively during peak hours. When the window is Sunday evening or a rainy day, everyone is sitting at home and loading the network to the maximum. Yes, so you will find out what your provider is capable of in “combat” conditions. But there is still 24 hours in the day, and you use the Internet not only in the evening rush hour.

3. If you connect via Wi-Fi, create the most objective conditions for the test – take measurements in the same room and without physical obstacles between the laptop and the modem.

4. Before checking, restart your computer. If your laptop has not rebooted for a long time, background processes may distort the ping score.

5. Do not use VPN during tests (for the same reason).

How to understand what is broken on your Mac. Turn on Apple Hardware Test

by

Apple computers have many useful features and capabilities. One of these features is the integrated hardware test.
With it, you can independently diagnose a computer malfunction, find an inoperative item and figure out the cause of the breakdown.
A performance test will not replace a full trip to a service center, but in some cases it will be very useful for ordinary users.
How to check your Mac at home

All modern Mac computers have a built-in utility for diagnosing the hardware of your computer. It allows you to check most of the nodes and components, identify malfunctions or a non-working element on the device.
There are two fundamentally different versions of the Mac diagnostic utility: Apple Hardware Test and Apple Diagnostics.
The first version of the program (Apple Hardware Test) runs on Mac computers that were released before June 2013, while newer models use the second (Apple Diagnostics).
Similar tests can identify problems with most of the Mac components. The system alternately polls drives, RAM, wireless modules, a power controller, a battery, and other computer components for errors.
Verification does not take much time, usually the equipment test passes from 2 to 5 minutes.
What you need to do before checking

Before starting the utility for checking the hardware, do the following:
▪️ Disconnect all peripherals from the Mac. You need to disconnect wired printers, drives, drives for disks, any third-party audio or video equipment, external video cards.
It is recommended to leave only the keyboard, mouse trackpad and monitor connected.
▪️ Before running the test on your MacBook, be sure to connect your laptop to a power source.
▪️ Make sure your Mac is connected via Wi-Fi or Ethernet cable to your network. In some cases, you may need to download additional files for testing.

3. Testing will start automatically. Wait until the check is completed, write down the received error codes or photograph them on your phone so as not to lose.
After the test is completed, the same actions will be available as in the previous case.
Why the hardware test does not start
The hardware test may not start and the Mac will continue to boot normally in the following cases:
Firstly, if you did not disconnect any third-party devices. Even connected flash drives or Type-C adapters can interfere with the test launch.
Secondly, if you use a non-original wireless keyboard with a Mac. Only the native Bluetooth keyboard can connect to the computer at the boot stage and send commands before starting the operating system. Only third-party wired keyboards will do.
Thirdly, the boot area of ​​the system with the test equipment may be damaged. At the same time, try to start the Mac with the Option (Alt) + D keys pressed. The computer will start the network diagnostic system.
Fourthly, the installed firmware password may interfere with the launch of the utility.
At the time of testing the computer, you should turn it off:
1. Reboot the Mac with Command + R keys pressed to boot in recovery mode.
2. In the menu bar, select Utilities – Utility for the firmware password (in some versions of macOS, the item is called Safe Launch Utility).
3. Click Turn off the firmware password and specify the previously set password.
4. Reboot the computer.
How to interpret test results
Apple Diagnostics test revealed no problems
After checking, you will see one or more error codes on the screen, for example:
ADP000 Code: No Mac Hardware Issues.
Codes CNW007 or CNW008: Inability to connect to the network or problems with the wireless module.
Code PPT001: Battery Issues on MacBook. This can be either too much battery wear, or problems with charging.
For details on all possible Mac hardware test error codes, visit Apple.
When to do a hardware test
Apple Diagnostics test result with a couple of errors
If you study the proposed options for action in case of errors, you will notice that Cupertinians almost always recommend visiting a service center. Why, then, test equipment at home?
First, it’s recommended that you run a hardware test when you purchase a Mac in the aftermarket. So you can immediately identify broken modules or computer components.
Secondly, the test will come in handy in case of problems after an independent Mac upgrade.
Thirdly, before going to the service center, it will be useful to yourself to know about possible problems with the computer.
Don’t be lazy to run Apple Hardware Test or Apple Diagnostics if your Mac starts acting weird. Testing will take only a few minutes, but you can immediately discard problems with the hardware and look for the cause in the software.
