What happens if you set a date? Factory reset and hard reset of Apple iPhone. Full iPhone content reset

February 2016 was a time of unprecedented demand for service Apple Center. People en masse took their favorite Apple phones to specialists because of one simple bug discovered by users. The fateful date of January 1, 1970, set on the iPhone, after turning off the phone, turned it into a useless piece of plastic (or in common parlance, a “brick”).

The discovery made by someone quickly spread across the Internet as a joke. It was published en masse by various communities in social networks. And often under the pretext that setting this magical date opens hidden functions phone. As a result, thousands and thousands of users disabled the gadgets with their own hands.

How did it all start?

Reddit users started talking about the fact that after installation on January 1, 1970, the iPhone “went crazy,” the exact algorithm that rendered the phone inoperative looks like this:

You need to go to your phone settings.
In the “Basic” tab, select the date and time settings item.
Move the slider to disable automatic change time.
Manually set the magic date to January 1, 1970. The time needs to be changed to 1:00.
After this, the owner reboots the phone and, voila, the phone stops working. It only appears on the screen and no manipulations help solve the problem.

Why did this particular date and time become the “root of all evil”? The point is that iOS system is based on UNIX. And in it, the countdown of time begins precisely from the designated date. In this regard, a theory of the problem was derived. When the user sets 01/01/70, the time value from the reference point becomes negative. Why negative and not zero? Simply because the iOS system will automatically adjust the displayed time to the time zone. A negative value “confuses” the hardware. As a result, the phone fails.

This problem could have remained a discovery of a narrow circle of people, which would have been “fixed” by developers in the future. If it weren't for the numerous jokers who began spreading evil jokes on the Internet. All of them were aimed at getting more users to set themselves the dangerous date of January 1, 1970. Which led to mass panic among iPhone users.

What is the “terrible power” of January 1, 1970?

After users followed the step-by-step instructions to set the specified date and time, the phone had to be rebooted. After which the treasured apple appeared on the screen and... that’s it. Then the phone no longer booted and gave the impression of a completely broken thing.

It is worth noting that not everyone immediately began to panic and rushed to specialists. Those who are familiar with technology, of course, tried to solve the situation on their own. But the reboot used in such cases (by pressing Home and Power) did not give any result. As well as recovery from using iTunes. In fact, there are still working methods, and you will learn about them later.

The curious thing is that this “trick” only worked on new phones with an A7 processor and subsequent versions. While 32-bit devices remained in their normal state after manipulation. In addition, even some users of gadgets with modern processors also did not suffer from this problem. To which the reason was expressed in online communities about the impact of the time zone in which a person is located. However, when testing this version in practice, several situations refuting the theory occurred.

Gradually, the number of people who got into this trouble by chance began to disappear, and experts developed ways that helped return everything “to normal.”

How to solve the problem with iPhone?

Users searched for options on their own. Among the solutions, one was proposed, which in the end turned out to be the only correct and working one. If you disconnect the battery or completely discharge the iPhone, the date January 1, 1970 will be reset.

And if completely discharging the problem did not solve the problem for everyone, then removing the battery helped 100%. It is important to note that performing the procedure on your own deprived users of the right to free warranty service. By the way, Apple manual for a long time remained silent regarding the issue. And repair or change devices for free in service centers refused.

How did Apple react to the problem?

The problem of January 1, 1970 was ignored by the company for some time, despite the crowds of users flocking to service centers.

But already on February 15, an appeal appeared on the official website, informing people about the dangers of changing the date. The management also recommended that everyone who managed to check the bug on their device should contact support.

Subsequently released iOS 9.3 corrected the mistake. After the update, users could change the dates as much as they wanted, including this ill-fated one. In any case, even after a reboot, the device continued to operate as normal.

Surely you also treat your smartphone as a treasure. But unfortunately, you don’t take care of it properly. Huffington Post journalists compiled a list of 11 usage errors. Subscribe.

11 mistakes in using iPhone

Ekaterina Bochkareva

1. Never turn it off

You really should turn off your phone at least once a week, otherwise the battery will drain faster than it should. According to experts, the battery deteriorates when we do not use the smartphone while it is on. If you use your phone as an alarm clock, consider replacing it with a regular cheap watches, or turn off your iPhone for a while during the day.

2. Leave Wi-Fi and Bluetooth always on

When both Wi-Fi and Bluetooth are turned on on your iPhone, but neither is used, energy is wasted. In everyday life, you probably don't need Wi-Fi and Bluetooth always on. It's better to turn them off and turn them on only when necessary.

3. Use it in bad weather

Your iPhone is not designed to withstand extremely hot or cold temperatures, so you shouldn't use it outside when it's below 0 degrees Celsius or above 30 degrees Celsius. Because of this, the battery is depleted, and the phone also freezes for a while. If you know in advance that you will have to go out in bad weather, turn off your iPhone or at least keep it in your pocket, away from the weather.

4. Leave it to charge overnight

While it's convenient to leave your iPhone charging overnight, some people think it's not the best idea. This topic has caused a lot of controversy. Many people agree on one thing: leaving the iPhone on after it's fully charged is harmful. Because of this, the battery deteriorates over time and the phone runs out faster.

“The battery will perform better if you disconnect it from the power source before it reaches 100%. Leaving your phone on a charger when it's already fully charged will reduce the performance of your smartphone slightly,” Gizmodo wrote last year. Try charging it throughout the day so it turns off immediately when fully charged. Well, or use a special timer for this.

5. Fully charge or discharge the battery

Lithium-ion batteries—the kind used in iPhones—work best when they're charged between 50 and 80 percent, Shane Broeski, founder of Farbe Technik, a battery-charging accessory company, told Digital Trends. On the other hand, if the battery is completely discharged, the battery will enter a “fully discharged battery state”, because of which the ions will not be able to hold a charge for long, Apple representatives note. By recharging the battery at short intervals, the battery ions receive enough energy to operate for a long time and increase its lifespan, he adds. Charging the battery is akin to having snacks and meal breaks throughout the day. Think of it this way.

6. You are not using an Apple charger

Apple chargers are expensive, but they're worth the expense. Using chargers from other brands may have negative effects on your phone. According to some reports, counterfeit chargers even cause fires and explosions. That's why Apple created a return program for USB charging adapters. According to it, since August 2013, in exchange for fake chargers, users received a discount on real Apple chargers. (Discounts were valid until August 18, 2013).

7. Don't clean it

Your iPhone looks disgusting. Well, it's really disgusting. There are fewer germs on your pet's toilet seats and dishes than on your iPhone. Apple recommends wiping your device with a “soft, lint-free cloth.” In addition, devices with ultraviolet radiation are used to disinfect the phone. Don't forget to clean the charging port. Debris from pockets and wallets gets stuck and accumulates there, causing connection problems. Use a toothpick, a thin needle, or the sharp end of an earring to remove dirt from there.

8. You walk around with your phone in your hands without noticing anything.

Whether you realize it or not, the iPhone is valuable thing on the black market and a desirable target for thieves. About 40% of thefts in large cities in 2013 were thefts of mobile devices. The American Federal Communications Commission reported this last year. Therefore, it is not safe to walk with your phone in your hands, with your head in the clouds.

9. They didn’t protect it with a password.

Half of iPhone users don't set a lock password on their phones, Apple reported in 2013. If you haven't set a passcode on your iPhone, if it's stolen, thieves will have full access to your data and personal information. A password is the easiest way to protect personal data from intruders.

10. Give access to your location to all applications in a row

Apps like Maps need "location access" in order to function correctly. However, they usually notify you when you need to enable this feature. Other applications work fine without geolocation. Go to Settings > Privacy > Location Services and deactivate the feature by disabling it in all non-essential applications. Your battery will thank you.

11. Allow push notifications in every application

Push notifications keep your phone on high alert and require a constant data connection, draining your battery. When the phone receives another notification, the display lights up, thereby reducing battery life. Researchers also found that notifications make it difficult to concentrate. Go to Settings > Notifications and select only one important app.
