This significantly extends the lifespan of your phone battery.
How long do you typically use an Apple or Samsung smartphone? Often, the contracts that come with such devices run for two years, after which you have the option to enter into a new contract with a device. This is a waste and far from sustainable; the device is typically still in good condition after two years. Only the phone's battery will typically have decreased in quality after two years. This does not mean that you have to replace the entire device; simply replacing the battery of your Samsung phone may be sufficient to keep going for some time. Not only is this sustainable, but it is also more cost-effective! Battery replacement can start from 30 euros, depending on the Samsung model you have.
