Most notably absent among side and front keys are an activator for the camera and a Nokia menu key. You get to the latter by pressing the select button in the centre of the D-pad, and to the camera by choosing Media from the menu screen and then opting for the Camera. Not unusual, but if you want dedicated keys you’ll need to look elsewhere.
This phone runs S40, which means it lags behind the swanky E and N series handsets and others that run the more capable S60. It is a tri-band handset so is to be avoided if you want 3G. It has 32MB of built-in memory, and you can use microSD cards to add more.
Nokia quotes battery life at up to 4 hours of talk and 300 hours on standby. My own battery test, which is a rundown of music playback that lets me compare almost all handsets using a unified benchmark, gave seven and a half hours of music from a full battery charge.
Setting this beside other S40 handset I’ve reviewed recently it compares unfavourably with the eight and a half hours delivered by the 7900 Crystal Prism and very unfavourably with the eco-friendly 3110 Evolve which managed close to eleven hours. There is an equaliser with presets for rock, pop, jazz and classical, plus two user presets.
There is an FM radio with RDS, but there's more bad news for music fans. Despite being mounted on the top of the 7310 Supernova, which is my optimum spot for it, the headphone/headset jack is of the 2.5mm variety. You'll therefore need a converter to use you favourite 3.5mm-equipped headphones.
Oddly enough for a handset positioned for the mid-market, the 7310 Supernova has a TV-out feature. The phone doesn’t come with a cable so you’ll need to buy that separately. This feature uses the 2.5mm jack and can send the contents of the screen to, well, a TV.
