You might have heard that there is a link between phone radiation and the level of your phone’s battery. Does the phone’s charge affect the radiation? So we’re going to find out is phone radiation higher when battery low?
What can affect phone radiation?
There are lots of factors that affect the level of phone radiation. But is the battery one of them?
Phone radiation is the electromagnetic field that the phone uses to communicate with the network. It also produces a small amount of EMF itself, as all electrical devices do. But the difference between a phone and other electrical appliances is that the phone uses much larger amounts of radiation to stay in touch with the network – constantly.
Even when you aren’t actively using your phone it is always checking in with the network ready to receive calls or messages, using data in the background and more. Airplane mode can help with this but it’s no good if you still want to receive calls and messages.
So because radiation is how the phone connects to the network it is a big factor in the radiation your phone gives off. When network coverage is low and there is poor signal the phone works much harder to connect, putting out much higher amounts of radiation. Low signal is one of the biggest effects on phone radiation.
Each make and model of phone is designed and manufactured differently so each will have a different amount of radiation it emits. Manufacturers have limits they must adhere to, called the Specific Absorption Rating, or SAR, which is what cell phone radiation is measured in. These are set by governments and the phones must be tested against them. There is an upper limit but different phones will have different amounts of SAR, with some being lower than others.
You can check your phone’s SAR in the manufacturer handbook that came with your phone, and sometimes on their website.
Is phone radiation higher when the battery is low?
Radiation is higher when there is low signal, but what about low battery?
There’s little evidence that phone radiation is higher when the battery is low – but then there is little evidence about mobile phone radiation in general.
A huge study that said mobile phone radiation was “cooking sperm” found a big link between using a mobile phone while it is charging and higher radiation. The conclusion was that people – especially men – should not use their phones while they are on charge.
Another reason for people thinking there is a link is actually the opposite – that high radiation drains your phone battery quicker, leading to a low battery and high radiation being seen together. But this is because the more radiation a phone puts out the harder it is working, so the faster it drains the battery.
So a low battery isn’t necessarily a cause of high phone radiation. But 21there are lots of things you can do to reduce radiation when using your phone.
- Use airplane mode or switch off your phone when you don’t need to use it.
- Try to keep a good signal – especially when making calls or using your phone.
- Check the SAR of your phone and of new phones when you are shopping around.
- Never use your phone when it is charging.
- Try an anti-radiation mobile phone case like WaveWall Flip and WaveWall Universal to cut mobile phone radiation by 85%.
Protect your body, your health and your fertility. The new WaveWall Universal gives you all-round protection from mobile radiation. Suitable for a wide range of phones.
Mobile phones use an electromagnetic field that produces radiation in order to work. It powers everything that allows your phone to communicate. This keeps happening even when you aren’t actively using the phone and are just carrying it around.
We keep our phones close but that also means keeping ourselves within their electromagnetic field and subject to radiation. Mobile radiation has been linked to cancer, tumours and male infertility.
