I've had my Dual Sim Nokia C1 phone since 2008 it lasts approx three weeks before it needs charging, never had a problem with it. I did buy the new version Dual Sim Nokia 108 brand new three months ago for £10 and it looks the same but has a touch screen so I've put it away because I don't want to put finger marks on the screen, I suppose one day I will force myself to use it if my C1 ever lets me down but hopefully it will last another ten years or more
