Why solar powered phones never took off
The concepts look cool, but are they practical?
Chinese company Infinix demonstrated several peculiar concept devices at MWC 2025. One of them caught my attention: a smartphone with built-in solar cells. They cover most of the device's back and provide up to 2W of power in ideal conditions. This sounds like a good idea when even the phones with the best battery life last no more than a couple of days between charges. Yet, no phone maker has launched a solar-charging Android smartphone. Why is that?
