When the battery depletes, your phone will simply do what it needs to do to stay powered on for that little bit longer. It wouldn’t really make sense for phone radiation to increase with 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. Radiation is higher when there is low signal, but what about low battery? Is Phone Radiation Higher when the Battery is Low?
You can check your phone’s SAR in the manufacturer handbook that came with your phone, and sometimes on their website. There is an upper limit but different phones will have different amounts of SAR, with some being lower than others. These are set by governments and the phones must be tested against them. Manufacturers have limits they must adhere to, called the Specific Absorption Rating, or SAR, which is what cell phone radiation is measured in. Low signal has one of the biggest effects on phone radiation.Įach make and model of phone is designed and manufactured differently so each will have a different amount of radiation it emits. When network coverage is low and there is a poor signal the phone works much harder to connect, putting out much higher amounts of radiation. So because radiation is essentially how the phone connects to the network, it is a big factor in the amount of radiation your phone gives off. Airplane mode can help with this but it’s no good if you still want to receive calls and messages. It is really going all out to try and locate the network and connect you.Įven 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. This is evidence of your phone routing all available power to the antennae. Sometimes, you may even feel your phone heat up in your hand if you’re trying to make a call in an area with poor signal. The more your phone is trying to connect to the network, the more radiation it pumps out. 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. It also produces a small amount of EMF itself, as all electrical devices do. Phone radiation is the electromagnetic field that the phone uses to communicate with your mobile phone network. There are lots of factors that affect the level of phone radiation.
