iPhone turns off in cold weather and slows down, especially in cold weather

07/12/2021 by

With the onset of freezing weather, users’ complaints about the incorrect operation of iPhone smartphones have become more frequent. According to users, in subzero temperatures, mobile devices are discharged much faster than usual, or they turn off completely unexpectedly. Why is that?

Why the iPhone slows down and turns off in the cold

Problems with the operation of the iPhone at temperatures below zero are not far-fetched – the harder the frost, the worse the communicator works. In the best case, the user is expected to fail in the system, in the worst case, the device will signal a low battery and turn off. However, there is no reason to express dissatisfaction with the incorrect operation of the gadget – on the Apple website there is a message that the stability of the operation of “apple” smartphones and tablets directly depends on the air temperature. It also directly states that if the thermometer falls below zero degrees, the devices may malfunction.

Using your iPhone or iPad in cold temperatures (below 0 ° C) may temporarily reduce battery performance. Once the temperature returns to normal, the battery performance will return to its previous level.

Nevertheless, despite the fact that at low temperatures the communicator signals a decrease in charge, it remains the same. The fact is that in the cold, the density of the gel-electrolyte in the battery of the device changes, which affects the speed and quality of the gadget. At the same time, the battery controller captures the changes and recognizes them as a decrease in charge, followed by an automatic shutdown of the smartphone.

Apple says the ideal operating temperature for iPhones and iPads is between 16 ° C and 22 ° C.

The frost also affects the operation of touch screens. When the device freezes, the screen starts to “slow down” noticeably. Only AMOLED displays are not strictly dependent on the external temperature.

Unlike Apple, which strictly regulated the ideal temperature range for working with its gadgets, falling outside of which the device may lose guaranteed service, competitors do not set similar rigid limits. So, gadgets from a number of manufacturers work without failures and at temperatures below -10 ° C. But at the same time, one must understand that the limitations of the “apple” company are dictated not by flaws in the technologies used, but by the notorious desire to create ultra-thin smartphones and tablets. Decreasing the thickness of devices affects their operation at low (below zero) or high (above + 35 ° C) temperatures.

Nevertheless, it is quite possible to avoid problems in using iPhone smartphones in severe frosts. To do this, you need to understand that the device will not be able to work on the street for a long time, and therefore you should limit the time of interaction with it as much as possible. It is also advisable to carry your smartphone in an inner pocket of warm clothes or in a case. Even the simplest silicone case can significantly extend the operating time of the gadget. The best option would be to buy a thick felt case for the iPhone communicator, which will save the device from the undesirable consequences of being in low temperature conditions.

It can also help prolong the operating time of the “apple” communicator by running a resource-intensive program or game in the background, which will increase the temperature of the microchip and, consequently, affect the overall temperature of the gadget.

But what if the iPhone still turns off after being out in the cold? First of all, you need to remember that it is extremely undesirable to dry it yourself and connect it to a charger. Better to leave it in a warm room for 1-2 hours. During this time, the gel in the battery will return to its original state and the condensation will dry out.

If there is an irresistible desire to recharge the frozen gadget without fail, then you should know that a sharp temperature drop can cause deformation and depressurization of the smartphone case and further fire or explosion of the device due to the reaction of lithium and oxygen. Apple will not pay the loss from such an incident, because, as already mentioned above, the company disclaims responsibility for the operation of the device if it was in conditions of low or high temperature.

How to use an iPhone in cold weather

Use a case – iPhone will hypothermia more slowly;
Store your smartphone in a pocket that is closer to your body;
Do not use the device in the cold for more than 5 minutes;
Warm up iPhone gradually – condensation may form in the case from a sharp temperature drop;
Do not charge your smartphone in sub-zero temperatures.

The Weather app in iOS 15: an overview

23/08/2021 by ALOK DAS

In 2020, Apple acquired the popular Dark Sky weather app, and in iOS 15, some of the program’s features were included in the official weather app. The Weather app’s design has undergone major changes in iOS 15, making it much more useful for predicting future weather.

Significant design changes

The Weather app in iOS 15‌ has a redesigned design that makes it easier than ever to quickly see the information you need. The Weather application uses an interface in the form of cards with the division of various information into sections.

There is still a basic view with hourly weather forecasts that you can toggle, and a new 10-day forecast view lets you know what kind of weather you can expect in the next few days. The updated 10-day forecast shows expected conditions and has a visual bar for displaying temperatures. This allows you to assess the changes over the coming days at a glance.

Scrolling down in the Weather application will take you to new modules that have added additional graphical weather data. There are modules for assessing air quality, temperature, UV index, sunset and sunrise times, wind strength and direction, precipitation, humidity, visibility and pressure.

For each of these modules, Apple provides graphics, descriptions, and additional information that was not previously available. For example, Apple shows the specific wind direction and provides detailed data. This can be a forecast of the time of the next precipitation, the level of ultraviolet radiation during the day, temperature adjusted for humidity, dew point, and more.

Weather maps

With iOS 15, Apple introduced full-screen weather maps that provide an overview of expected rainfall, air quality, and temperature. You can navigate to maps by clicking on the default temperature map and then clicking on the stacked button to change the view to show precipitation or air quality.

It is also possible to access weather maps from anywhere in the Weather application. To do this, you need to click on the small icon of the folded card in the lower left corner of the window.

Interestingly, precipitation maps are also animated and show the trajectory of approaching storms and the intensity of rain and snow, while air quality and temperature maps allow you to see the current conditions both in your area and in the surrounding area. You can zoom in or out with your fingers as needed.

True, air quality information is limited to Canada, mainland China, Germany, France, India, Italy, Mexico, the Netherlands, South Korea, Spain, the United Kingdom and the United States.

Animated background

In addition to the updated design, the Apple Weather app offers hundreds of new animated backgrounds that provide additional information about the position of the sun, rain, clouds, storms, and other weather events. The background changes automatically day and night and is selected depending on the weather conditions.

Animated backgrounds are available on all devices with A12 Bionic chip or newer. Unfortunately, earlier versions of the iPhone won’t have access to such detailed animations.

Weather UV index, what it is and how to check it on iPhone, Apple Watch or iPad

26/05/2020 by ALOK DAS

Enjoying warm sunny days, do not forget to monitor the UV index. This indicator of solar energy indicates the level of ultraviolet research. It is already widely known that it is necessary to protect yourself from the sun not only because of possible burns, but also for the health of the body as a whole.

Modern technologies make it possible to check the radiation power of the Sun at any time using the iPhone or Apple Watch and the standard weather application installed in them. The UV index directly determines how long you can stay in the sun without harm to the body.

Clarification of UV Index Values

So, you got the index value, it remains to understand what it means. The number you saw in the Weather app for ultraviolet light indicates how quickly you can burn out in the sun or how long it’s safe to stay in it. We give a classical interpretation of values. Please note that we are talking about skin unprotected by special means, while the body of each person also individually responds to radiation.

0: the energy of the sun is practically absent, the skin does not blush, burns can not happen.

1-2: almost no solar energy, the skin turns red within 50-100 minutes the probability of a burn is zero.

3-4: weak solar energy, the skin turns red after 25-35 minutes, a small chance of sunburn.

5-6: moderate solar energy, 15-25 minutes are allowed for a light tan of the skin, then it turns red

7-8: strong solar energy, sunbathing is permissible for 10-15 minutes, after which the sunburn occurs quickly.

9-10: increased solar energy, the skin turns red within 10 minutes, a very high probability of burns.

It is important to know that air temperature has no direct effect on solar energy. On a cool but sunny day, the power of the sun can be even stronger than on a warm day.

How to Check UV Index on iPad

Unfortunately, the iPad does not have Apple’s proprietary weather application, but you can still check its forecast by simply asking Siri. This can be done using a command, for example: “What is the weather like today in the” name of the city? “”.

On Siri’s weather card, click on the box that says “The Weather Channel” in the lower right corner to go to weather.com.

On the website that opens, the UV index for the selected city will be indicated.

In addition, you can also view the weather and UV index on the iPad, in a third-party weather application, for example, from Yahoo.
