This warning underscores the potential risks and negative impacts on users' health and well-being associated with sleeping in close proximity to a charging phone.

Risk of fire

Apple has warned iPhone users against sleeping next to their phones while charging, citing safety concerns, including the risk of fire. In its updated iPhone User Guide, Apple cautions users about the potential dangers of charging their phones in bed. The company states that iPhones, power adapters, and wireless chargers can generate heat during the charging process, and if this heat is not released properly due to being placed in confined spaces like under a pillow or blanket, it poses a fire risk.

The iPhone User Guide advises users to "use common sense to avoid situations where your skin is in contact with a device or power adapter while it is running or connected to a power outlet for a long time." It further instructs users not to sleep on or place their devices, power adapters, or wireless chargers under blankets, pillows, or their bodies when they are connected to a power source. Instead, Apple recommends keeping the iPhone, power adapter, and any wireless charger in a well-ventilated area away from the body when charging.

The warning emphasizes that failure to follow these safety instructions could result in fire, electric shock, injury, or damage to the iPhone or other property. Apple also advises taking special care if individuals have a physical condition that affects their ability to detect heat against the body.

Additionally, Apple warns against using damaged cables or chargers and charging in damp places, such as near a sink or bathtub. The company recommends using only certified Made for iPhone products that meet Apple's performance and safety standards to reduce the risk of fire and other hazards.

Risk of electric shock

Apple has warned consumers against sleeping with their iPhones charging, as the devices, cables, and chargers can get warm and cause discomfort or even injury if pressed against the skin for a long period of time. The company advises users to use common sense and avoid situations where their skin is in contact with a device or power adapter while it is running or connected to a power outlet for an extended period.

In its latest iPhone user manual, Apple specifically states:

> "Don't sleep on a device, power adapter, or wireless charger, or place them under a blanket, pillow, or your body, when it's connected to a power source. Keep your iPhone, the power adapter, and any wireless charger in a well-ventilated area when in use or charging. Take special care if you have a physical condition that affects your ability to detect heat against the body."

The warning highlights the potential risk of fire or electric shock, which can occur if the heat generated during the charging process cannot be easily released due to confined spaces. This risk is especially prominent when charging on soft surfaces such as blankets or pillows, or directly on the body.

Apple also recommends using only certified charging accessories, as uncertified products may not meet safety standards and can lead to electrical leakages, unstable voltage output, and potential electric shock. In addition, it is advised to regularly inspect charging accessories for any signs of damage or wear and tear, as using damaged cables or chargers can also increase the risk of fire or electric shock.

To ensure safe charging practices, it is important to follow Apple's guidelines and charge iPhones in well-ventilated areas, on flat surfaces such as tables, and avoid charging on soft surfaces or near sources of moisture. By taking these precautions, users can minimize the risk of electric shock and potential injury.

Risk of injury

Apple has issued a warning to iPhone users, urging them to avoid sleeping with their phones while charging. The latest iPhone User Guide includes a clear cautionary message for individuals who have a habit of falling asleep while holding their smartphones, especially when the device is connected to a charger. This practice can lead to several risks of injury.

Firstly, iPhones generate heat during the charging process, and if this heat is trapped due to confined spaces, it can cause burns. Prolonged contact with the hot surfaces of the device, cables, or chargers can lead to discomfort or even injury, especially if pressed against the skin for extended periods. Apple advises keeping the iPhone and any chargers in a well-ventilated area away from the body when charging to prevent heat-related injuries.

Secondly, the combination of a running device and soft surfaces, such as blankets or pillows, can create a fire hazard. The heat generated by the phone may ignite surrounding fabrics or materials, leading to a potential fire. Apple explicitly warns against placing the phone, power adapter, or wireless charger under blankets, pillows, or your body when connected to a power source.

Thirdly, charging iPhones overnight in bed can also lead to electric shock. Apple's user guide states that failure to follow safety instructions, such as charging in well-ventilated areas, could result in electric shock, injury, or damage to property.

Additionally, individuals with health conditions that affect their ability to detect heat against the body are at an even higher risk of injury. Apple advises taking extreme precautions if you have such a condition.

To ensure safety, Apple recommends charging iPhones on flat, solid surfaces in well-ventilated areas away from the bed. This practice will help prevent heat-related injuries, reduce the risk of fire, and lower the chances of electric shock.

Risk of damage to your phone

Apple has issued a warning urging iPhone users to avoid sleeping with their phones while charging. The latest edition of the iPhone user manual states that devices, cables, and chargers can get warm and cause discomfort or even injury if pressed against the skin for long periods. The manual further advises users to avoid placing their iPhones under blankets, pillows, or their bodies when connected to a power outlet.

The risk of charging your iPhone overnight or while sleeping is that it can generate heat, which may cause discomfort or, in rare cases, even lead to burns or fires. This is especially true if your phone is in a case, as it will trap the heat and make it harder for the phone to cool down. Additionally, if you stack anything on top of your phone while it's charging, such as books or other devices, it will restrict airflow and cause the phone to get even hotter.

While the risk of fire may seem remote, it is not unheard of. In the case of Samsung's Galaxy Note 7, for example, there were several incidents of phones bursting into flame due to battery issues. Apple's user manual also warns against using damaged cables or chargers, as they may pose a risk of fire, electric shock, or other serious injury.

To minimise the risk of damage to your iPhone, it is recommended to follow Apple's guidelines and keep your phone in a well-ventilated area when charging. Take it out of its case if possible, and avoid stacking anything on top of it. It is also worth noting that Apple advises against charging your iPhone in environments hotter than 95 degrees Fahrenheit (35 degrees Celsius), as this can cause permanent damage to the battery.

In summary, while charging your iPhone overnight or while sleeping may not always lead to damage, it is important to take precautions to minimise the risk of fire, injury, or damage to your device. By following Apple's recommendations for safe charging practices, you can help ensure the longevity of your iPhone and maintain your safety.

Interference with medical devices

Apple has warned iPhone users to avoid charging their phones while sleeping, as the devices, cables, and chargers can get warm and cause discomfort or even injury if pressed against the skin for a prolonged period. Another reason to heed this warning is the potential interference of iPhones with medical devices.

Most consumer electronic devices, including iPhones, contain magnets, components, and radios that emit electromagnetic fields. These electromagnetic fields can interfere with medical devices such as pacemakers and defibrillators, which may contain sensors that respond to magnets and radios when in close contact. Radio frequency energy (RF) from cell phones can interact with some electronic medical devices, causing electromagnetic interference (EMI).

EMI can potentially affect the functionality of vital medical equipment, including ventilators, ECG monitors, cardiac monitors, and defibrillators. While the possibility of interference from 4G phones with medical devices is considered to be low, it is still a concern for 2G and 3G phones.

To prevent potential interference, it is recommended to maintain a safe distance between the iPhone and the medical device. Most medical device manufacturers recommend keeping a distance of at least 6 inches (15 cm) between the iPhone and the medical device, or at least 12 inches (30 cm) when using a wireless charger. Apple also advises users to consult their physician and the medical device manufacturer for specific guidelines, as manufacturers often provide recommendations on the safe use of their devices around wireless or magnetic products.

If you suspect that your iPhone is interfering with your medical device, it is important to stop using it and consult your physician and the medical device manufacturer to address the issue.
