Misleading and Inaccurate Warning – ‘Don’t Answer Calls While Charging Cell Phone’

by Brett M. Christensen


Social media message claims that a boy died in Mumbai because he took a call while his mobile phone was charging. The message also claims that people should not make or answer calls when a mobile phone’s battery is low because the radiation is 1000 times stronger.

Brief Analysis

The message is most likely derived from an Indian news report describing an incident in which a boy was seriously injured when his Chinese made mobile phone exploded in his hand while it was being charged. However, the boy was not killed as claimed in the message. There have been several reported incidents of injuries or deaths attributed to using mobile phones while they were being charged. But, in virtually every case, faulty or counterfeit phones or charges were being used. And the claim that radiation from a mobile phone is one thousand times stronger when the battery is low is misleading and inaccurate.



Today another boy died in Mumbai, because of attending a call while his mobile was still charging. That time he had a sudden vibration to his heart and then his hands got burned.

So please don’t answer calls or call out while charging your cell phone. When the phone’s battery is low to the last bar don’t make a call or answer any incoming calls because the radiation is 1000 times stronger. This can happen to any brand of mobile phones out there.

Mobile Phone Death Charging Warning

Detailed Analysis

A message that has been circulating via social media since 2014 claims that a boy died in Mumbai after taking a call while his mobile phone was being charged. According to the message, the boy experienced a “sudden vibration to his heart” before having his hands burnt. Thus, warns the message, people should not answer or make mobile phone calls while the phone is being charged. The post features an image depicting a boy with a lacerated hand and wounds to his face, lying in a hospital bed.

The message tacks on an extra warning that claims that people should never make or take calls when their mobile phone battery is low because radiation is a whopping 1000 times stronger at that time.

The warning is apparently derived from a January 2014 Indian Express article describing an incident in which a boy was injured when his phone exploded in his hand. The report notes:

A 10-year-old boy from Dewas district was seriously injured when a mobile phone, said to be of Chinese-make, exploded in his hand while charging, police said today.

The incident occurred last night when Arihant was playing games on the handset while charging it at his home at Uday Nagar village, 100 km from here, they said.

However, the boy did not die as claimed and is reportedly out of danger.

In fact, as detailed by rumour debunking website Wafflesatnoon, there have been several reports in recent years of injuries or deaths related to use of a mobile phone while it was charging. But in every report I have seen, faulty or counterfeit products were being used.

An article about battery charger devices on explains how such devices transform normal household AC current down to a low voltage DC current. Thus, if the charger is working correctly, no high voltage charge should ever reach a person using the device.

But, if non-standard charging units are used or the phone has counterfeit or poor quality parts, then there is always the possibility that the charging mechanism will work incorrectly and cause injury or death to users.  In fact, this is true for any device that is plugged into mains power.

However, there is no inherent or explicit danger in using a properly working mobile phone being charged with the appropriate and properly working charging unit. Moreover, the act of using a mobile phone while it is charging is repeated many thousands of times per day all over the world without incident or injury.  This is especially true in an era when people use their smartphones constantly and for a great deal more than just making or taking phone calls.

While it is likely derived from the 2014 Indian Express report, the warning message also pays allegiance to a much older warning that has circulated since 2004. The original version was in turn derived from a 2004 Indian news report that describes the electrocution death of a man who answered his mobile phone while it was charging. But, details of the Indian man’s demise are sketchy at best. It is again likely that the man was using faulty or non-standard equipment.

Furthermore, the claim in the message that using a mobile phone while the battery is low increases radiation exposure one thousand times is misleading and inaccurate. This claim has circulated for several years in other contexts.

A weak signal rather than a low battery level may increase radiation. A WHO report on Electromagnetic fields and public health notes:

Using the phone in areas of good reception also decreases exposure as it allows the phone to transmit at reduced power.

There have been some suggestions that a phone with a low battery has to “work harder” to find and maintain a signal, but I could find no clear evidence to support this.

Perhaps the author of the message meant to warn that radiation might be stronger when the signal indicator was on the last bar rather than the battery level. A discussion of this issue on Skeptics Stack Exchange notes that:

There is no direct causative link between handset battery charge level and handset transmit power level.Regardless of battery charge, when you are standing next to a transmission tower your handset is only outputting the minimum power needed to communicate. Not the maximum.


Whilst a 1000 fold variation in power is of the right order of magnitude, your handset’s battery level indicator is not a useful indicator of the amount of “radiation” currently emitted by the handset (in talk mode).

This supposed warning contains false and misleading information and sharing it with others is counterproductive.

Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
