When temperatures start to drop, you may start experiencing something unusual with your devices. Many iPhone users have experienced their iPhones turning off in cold weather.
Why Does my iPhone Turn off When it’s Cold?
Phone manufacturers have warned their users that their device can turn off as temperatures drop and they should expect it.
This may sound weird but your iPhone or your other devices can actually turn off when the temperature is too cold and you’re not the only one that’s experiencing it, many iPhone users have reported this issue and they want to know why it’s happening.
The reason your iPhone turns off when it’s cold is due to the lithium-ion battery inside. In a lithium-ion battery, each cell is made up of a positive electrode, a negative electrode, and an electrolyte in-between each cell.
When the temperature of your iPhone drops below freezing, the electrolyte liquid inside the lithium battery crystallizes. This prevents a current from flowing through the battery which stops the iPhone from working, which is why your iPhone will turn off.
On the Apple support website, here’s what they say, “Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off.
Battery life will return to normal when you bring the device back to higher ambient temperatures”.
iPhone Touch Screen Bug
Here’s what a spokesperson at Apple said, “We are aware of instances where the iPhone X screen will become temporarily unresponsive to touch after a rapid change to a cold environment.
After several seconds the screen will become fully responsive again. This will be addressed in an upcoming software update”.
You can update your iPhone to the 11.1.2 iOS update which fixes the bug and many users have also said that it fixed the issue.
There may be Something Wrong with your Battery
Another reason why your device may be turning off due to cold weather is that your battery is damaged.
You may think that your iPhone turns off because it’s cold but it may be because of a feature Apple have which asses the condition of your battery then turns it off if it’s in a bad condition.
One of the factors they use to assess this is called the device temperature. This feature is called Performance Management, and this can be turned off if you have access to the Battery Health feature which is only available in iOS 11.3.
To turn off performance management:
- Go to the Settings App
- Scroll down to Battery
- Tap on ‘Battery Health’
- Look under ‘Peak Performance Management’ and click on ‘Disable’
Note that If you’ve turned off performance management, your device may still shutdown unexpectedly in the future.
How to Stop iPhone From Turning off When it’s Cold
The first thing you can do to stop your iPhone from turning off when it’s cold is to simply increase the temperature of your battery.
You can do this by keeping it somewhere warm such as under your pillow.
If you live in a cold climate, leave your phone in your pocket most of the time so that it can have time to warm up.
Here’s the temperature that Apple Support recommends, “Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range”.
Replace your iPhone’s Battery
The last thing you can do to fix this problem is to simply replace your battery because the chances are, your iPhone is turning off randomly is because the battery is worn out and when it’s cold, this can happen more often.
You can get your battery replaced for $29 until the end of 2018 but you have to have an iPhone 6 or above.
You can go to the Apple store nearest to you and set up an appointment to replace your battery. This can take a few weeks.
