Stop your phone from overheating: remove the case and turn on power saving mode, but don’t put it in the freezer.

As Britain prepares for the hottest day on record – temperatures are expected to hit 43°C (109°F) tomorrow – your phone’s health is unlikely to be the focus of your attention.

But how Mercury rises, smartphone and tablet users may find their devices stop working or turn off unexpectedly.

This is because the lithium-ion batteries used in most modern gadgets can be damaged in extreme temperatures, so manufacturers include built-in protections that can cause devices to shut down when they overheat.

Apple, for example, warns that high temperatures “may cause your device to change its behavior to regulate its temperature.”

These changes may include slowing down or stopping charging, dimming or dimming the display, weaker signal, slower performance, or temporarily turning off the camera flash.

If the device exceeds a certain temperature threshold, it will display a temperature warning screen that will disable all features except emergency calls.

“To resume using your device as quickly as possible, turn it off, move it to a cooler location (out of direct sunlight), and let it cool down,” Apple said in a statement.

iPhone users will see a temperature warning screen if their device exceeds a certain temperature.

Meanwhile, Samsung states that: “If your device is overheating, it will display a notification that it is getting hot. If your device overheats, it will turn off.”

While these measures are meant to protect devices, Uswitch warns that excessive heat and direct sunlight can cause permanent damage to many gadgets.

And it’s not just mobile devices that are at risk – routers, computers and consoles require good ventilation to get rid of excess heat during use.

“In addition to taking steps to protect against extreme weather, it’s important to remember that not all technology can withstand the heat,” said Katherine Haley, Uswitch.com’s telecommunications expert.

“Most modern devices can withstand temperatures up to 35 degrees if they are well ventilated, but unusually hot weather or leaving the device in the sun can cause these temperatures to rise quickly.”

Here MailOnline has collected tips from gadget experts. Uswitch as well as Sun-Sure how to cool down your devices during the heat – and what not to do!

1. Remove the body

One quick way to reduce the risk of your phone overheating is to remove the case, as built-in cases keep the heat in.

Just make sure you don’t drop it when you’re out in the sun, as you could end up with a cracked screen!

2. Keep it away from direct sunlight

Leaving the phone in direct sunlight can cause temperatures to rise above safe levels, with Apple warning that the iPhone performs best below 35°C (95°F).

If you are outside, try to keep your phone out of direct sunlight and never leave it in a hot car.

3. Switch to power saving mode.

If your phone is doing a lot of tasks that it doesn’t need and also running a lot of apps that you don’t use, it can cause your phone to overheat.

Run a background refresh and close all unnecessary applications, and if this fails, try putting the device into power saving mode to save energy. This ensures that it doesn’t always run at full capacity and will help prevent overheating.

4. Reduce screen brightness

Lowering your phone’s brightness settings will reduce the amount of battery you use and also prevent your device from overheating.

5. Avoid using the camera

While summer is a great time for photos and videos, try not to use your phone’s camera for long periods of time.

Constant snapping can cause it to overheat as well as potentially being exposed to the sun.

6. Place in front of a fan

If you feel like your phone is overheating, put it in front of a fan. Cool air steadily reduces it to normal temperature.

If you don’t have a fan, place it in a dark, cool place out of direct sunlight.

If you keep your phone in your pocket on a sunny day, body heat will raise the temperature of your device.

7. Don’t put it in your pocket or under your pillow

If you keep your phone in your pocket on a sunny day, body heat will raise the temperature of your device, so it’s best to put it in a bag or on a table to keep it well ventilated.

You should also avoid sleeping with your phone under your pillow, as this can stop heat from escaping and cause it to overheat.

If you make this mistake, you can try rebooting your device to let it cool down and calibrate itself.

8. Never put it in the freezer

While it’s tempting to quickly chill a hot tube in the freezer, don’t do it – it can exacerbate the problem.

Sudden changes in temperature can cause condensation to form inside your device, which can damage your equipment.

Instead, leave it on a cool surface with good airflow.

Why is it so hot in the UK this week?

Today in Britain could be the hottest day on record, with temperatures forecast to rise to 41°C (106°F).

But why is there such a sweltering heat in the country?

Experts say this is due to a number of factors, including winds blowing hot air from North Africa and the Sahara, the Azores’ subtropical high pressure system sliding further north, and the ongoing impact changing of the climate.

This led to with office issuing a red extreme heat warning for much of England today and tomorrow, and health officials are declaring a “national emergency”.

There are fears that hospitals will be overwhelmed, schools may be forced to close and transport services may come to a halt due to train cancellations and melted roads.

London promises to be one of the hottest places in the world as temperatures are higher than in Western Sahara and the Caribbean. The current highest temperature in the UK is 38.7 °C (101.7 °F), recorded in Cambridge in 2019.

One of the reasons for the hot weather is that the pressure system called the Azores High usually doesn’t work. Spainincreased in size and pushed to the north.

The Azores Highlands are usually to the south, but currently they are directly above Great Britain and Ireland, extending from the Azores.

The Azores Highlands are usually to the south, but currently they are directly above Great Britain and Ireland, extending from the Azores.

This brought scorching heat to Britain, France and the Iberian Peninsula.

High pressure near the southern half of Britain, which caused recent warm weather, also continues to dominate overhead.

When this develops, it causes heatwaves, which can also lead to so-called “tropical nights” – when nighttime temperatures don’t drop below 68°F (20°C).

These heatwaves are becoming more likely and more intense due to climate change.

Meanwhile, the winds shifted to the south late last week, bringing hot air from North Africa and the Sahara and allowing the UK to get some of the 113°F (45°C) heat from Spain and France.
