Nokia 3110 Evolve eco-friendly mobile phone

The music player’s performance is, on the other hand, perfectly acceptable for a bit of occasional tune-playing. The stereo earphone set supplied is adequate for the job and delivers reasonable sound quality. It plugs into a 2.5mm socket on the base of the phone, so if you wanted to upgrade the listening experience with better headphones you'll have to invest in an adapter or try a Bluetooth set - the Evolve supports A2DP.

There’s only a paltry 9MB of user memory to play with, so you’ll need a Micro SD card to get any music mileage out of the phone. Unfortunately, there isn't one supplied with it.

Similarly absent from the standard package is a USB cable, something we’d normally expect. This is a tad frustrating if you want to transfer content from a PC immediately.

You can copy tracks across from a PC using a memory card reader or via Bluetooth. This phone also has infrared too. Even if you don’t want any music-copying hassle, you could still enjoy a bit of music thanks to the efficient integrated FM radio that is simple and straightforward to use.

Sing if you're glad to be grey

Of course, when it comes to socketry and the like, the 3110 Evolve in-box package does offer something different: a Nokia "high-efficiency" charger. This is one of the environmentally friendlier elements this phone delivers, and we expect it to become the standard Nokia charger before too long. The charger is designed to minimise no-load charging if it’s left plugged in when the phone’s removed, so cutting down energy wastage.

Illustrating why this technology is important for reducing energy consumption, Nokia estimates that if all its phone users across the world unplugged their chargers when not needed, it could save energy equivalent to that needed to power 100,000 average-sized European homes. So, more green points there, then.
