Apple warns against charging iPhones under pillows, blankets, or on soft surfaces where heat cannot dissipate—not against overnight charging itself. Using a quality charging station on a nightstand or hard surface is perfectly safe. Apple's Optimized Battery Charging feature further protects battery health during overnight charging sessions.
Apple recently updated its online user guide to warn iPhone users against charging their phones in bed. Sleeping with devices can lead to sleep deprivation and other problems, according to experts. To mitigate these risks, Apple strongly recommends that users prioritize charging their phones in adequately ventilated spaces. Additionally, they advise against tucking phones under blankets or pillows during the charging process.

Apple's Updated User Guide: A Wake-Up Call
A significant number of individuals have the habit of charging their iPhones on their beds, nestled among pillows and blankets. While this might seem convenient, health experts and doctors are cautioning against this practice. Why? The answer lies in the heat that iPhones generate during the charging process.
In a recent update to its online user guide, Apple issued a stern warning to iPhone users. The tech giant strongly advises against charging iPhones on soft surfaces, especially when placed on beds. The company emphasizes the importance of proper ventilation during the charging process. iPhones are designed to function optimally when placed on flat, hard surfaces like tables, which facilitate the dissipation of heat and prevent potential hazards.

Impact of phones on sleep
Beyond the concern of phone-related fire risks while charging, sleeping in close proximity to your phone can have negative impacts on your well-being.
In today's world, smartphones hold addictive qualities, offering a plethora of apps and games that provide instant gratification and endless opportunities for engagement. Breaking away from these activities and setting aside the phone can be challenging, resulting in delayed bedtimes and a decrease in overall sleep duration. This in turn contributes to sleep deprivation, a well-established factor for various mental and physical health issues.
A recent study conducted in 2020 revealed that curtailing phone usage before bedtime over a span of four weeks led to notable enhancements in both sleep quality and duration, along with improvements in working memory.
To address this concern, consider the NYTSTND wireless charger as an ideal solution. Not only does it facilitate charging, but it also encourages placing the phone away from the sleeping area, reducing temptation and allowing for a more restful sleep environment.

Our smartphones play a crucial role in our daily lives, but it's important to prioritize safety when charging them. Apple's guidance serves as a reminder that charging on soft surfaces can lead to overheating and potential hazards. By heeding this advice and adopting solutions like NYTSTND, you're not only safeguarding your devices but also creating a healthier charging habit.

Frequently Asked Questions About iPhone Charging Safety
Can my iPhone catch fire while charging overnight?
iPhone fires are extremely rare and virtually always involve counterfeit/uncertified chargers, severely damaged batteries, or incorrect charging practices (like under-pillow charging). Using an Apple-certified charger or quality third-party charger on a proper surface poses no meaningful fire risk.
Does overnight charging damage my battery?
Not significantly when Optimized Battery Charging is enabled. This feature limits time spent at 100% charge, which is the primary cause of gradual capacity loss. Modern iPhones are designed with overnight charging as a standard use case.
Should I charge my iPhone to 100% or stop at 80%?
For maximum battery longevity, stopping at 80-90% is marginally better. However, the difference over typical ownership periods is small. iOS 18's new Charge Limit feature lets you set a maximum level if you want to optimize for longevity. For most users, letting Optimized Battery Charging manage things automatically is sufficient.
Is wireless charging worse for my battery than wired charging?
Marginally, due to slightly higher heat generation. However, the difference is minor with quality chargers and unlikely to noticeably affect battery health over normal device lifespans. The convenience of wireless charging outweighs the minimal additional wear for most users.
My phone gets warm during wireless charging. Is this dangerous?
Warmth during wireless charging is normal and expected. The energy transfer process generates heat. "Warm to the touch" is fine; "hot" or "uncomfortable to hold" suggests a problem with the charger, case interference, or ambient temperature. If your phone regularly gets very hot during charging, investigate the cause.
Does Apple recommend any specific third-party chargers?
Apple doesn't officially endorse specific third-party products, but MagSafe-compatible and Qi-certified chargers have met relevant safety and performance standards. Look for these certifications when selecting a dedicated bedside charging solution.
