With global warming increasingly worrying, we are increasingly concerned about environmental protection products. The sources of renewable energy are appearing more and more attention, which inevitably makes us think of phones using solar batteries to protect the environment.
Solar phones have been around for a long time, including the Samsung S7550 Blue Earth, launched in 2009.
The most impressive feature on this machine is of course the solar charger on the back. The panels make the S7550 Blue Earth stand out and of course, more importantly, provide the ability to charge batteries with solar energy. An hour in the sun can provide about 10 minutes of talk time or 2 hours in standby.
The solar panel is integrated into the back cover and connected to the phone with a pogo pin, which is quite similar to Motorola's Moto Mods. There is a small blue LED that lights up when your phone starts charging from the sun, helping you realize you're using clean energy.
S7550 Blue Earth is an eco-friendly “from the start”. It is made from recycled PET from water bottles, packed in a box made of easily recyclable paper and printed with soy based ink. , Samsung has provided you with instructions on how to reuse the case as a picture frame or pen case.
S7550 Blue Earth has Eco mode that users can easily switch to use to extend battery life, this mode will turn off unnecessary connections and reduce the brightness of the machine.
A bit ahead of its time, like many phones today, the S7550 launched in 2009 has a step counter but instead of measuring calories burned, it calculates the amount of CO2 that will be released in the atmosphere if you drive. Car instead of walking. There is even a score system to encourage users to walk more.
Blue Earth is not Samsung's first solar-powered phone, but the E1107 Crest Solar, which appeared a few months earlier. It was also not the first phone to use recycled materials, but the E200 ECO since 2008. But both are basic feature phones with limited functionality.
In contrast, Blue Earth is a touch phone, though not quite a smartphone as we know it today, but it runs on the TouchWiz interface, which can perform some more advanced tasks than the phone. basic.
It has a 3-inch (240 x 400px) touch screen and allows you to browse the web via 3G or Wi-Fi. There is also a blogging application and can send MMS messages with photos taken with a 3.2MP camera on the back.
S7550 is capable of MP3 music and Bluetooth connectivity with A2DP, 3.5mm headphone jack with FM radio listening. There is even a document viewer that can handle Word, Excel and PDF files.
You might think Samsung Blue Earth would be the perfect phone if you're stuck on an island, desert or wilderness – with solar charging, you'll never run out of battery, In addition, you can have up to 16GB of storage to listen to music (if you use a microSD card) and a few pre-loaded games for entertainment while waiting for rescue.
In addition, there is also GPS and Google Maps. However, Google Maps does not currently support offline mode, so it is only useful when you have a strong 3G connection, but where to get stuck. Maps doesn't support navigation either, so you'll have to find your own way back to the civilized world.
However, it is a theory that no one wants to experiment on their own. First, the phone is not resistant to water, dust, and games and music will drain the battery faster than what solar can recharge.
Putting aside the dream that "Robinson gets lost on a deserted island", the truth is that phones with solar batteries have never been able to become popular. At least the recycling movement continues with more and more products using recycled materials, as well as old phone recycling programs.
Anyway, this is a step towards green life – clean – beautiful and S7550 Blue Earth is a product trying to develop that movement, but probably will not be remembered.
