The power of the sun in the palm of your hand
There are few things cooler than devices that charge with solar energy, which is why we decided to award Infinix’s Solar Energy Reserving Technology at Mobile World Congress 2025 this week. While this is still a concept, it’s also a practical idea that would be very beneficial to have. The process of creating something like this was surely anything but easy, but it is technology that would easily fit into your everyday life.
Infinix’s Solar Energy Reserving Technology came in more than one form at Mobile World Congress, but what grabbed our attention the most was this phone that had integrated solar cells. That’s just like it sounds. It’s a phone with a panel made up of small solar cells on the back that can charge via sunlight.
Solar charging tech has been around for a while, but it’s never really been incorporated into things like smartphones. Infinix envisions a world where your phone could charge from the light of the sun while you’re doing things like walking down the street or sitting by a window. This would be a great way to charge your phone when it’s not being used. That’s a very exciting thing to think about. Because it could eliminate the need to bring backup chargers everywhere.
The solar cells can apparently take in light from really bright lights
Charging from sunlight is pretty cool to begin with, but it’s even cooler if a device can charge from regular lights. That’s one thing that surprised us about the Solar Energy Reserving Technology that Infinix brought to Mobile World Congress.
According to the company, the cells on the back of the phone are potentially capable of charging with light that isn’t sunlight. It wouldn’t be a fast charge. Again, though, it should be enough if your phone is just sitting around and you’re not using it. Then, all you would need to do is leave it alone under those lights for a bit.
Infinix told us that the phone was able to charge via heat from other phones in the same bag as this concept phone. So there are some seemingly good possibilities here for how this phone could charge up throughout the day.
Infinix is putting this tech into cases too
Infinix isn’t stopping at phones with built-in solar cells for charging. It also took this same technology and incorporated it into a case for an upcoming phone it’ll be launching. So, even without this solar charging phone, you could still end up with a phone that can charge through solar power. This is the kind of cool innovation that we’d love to see more companies working on. They’re useful solutions to the ever-present issue that is smartphone battery life.
