It's a reasonable question. For a long time I was using two phones for exactly that reason: a Nokia 6310i for phone calls and an iphone for everything else. Unfortunately 6310i got damaged (the battery was still able to keep the phone running for more than 10 days!) and I bought a smartphone to act like a phone (a popular Android device). It's obviously superior to 6310i in several ways - for example text messages can be typed faster. However, the phone lasts only two days. With Nokia, I charged it once and forgot about it for two weeks. With a smartphone, I need to always remember to make sure the battery is at a reasonable level. If I had a chance to buy a genuine (not refurbished/clone) 6310i, I'd do it straight away.
