Is it worth it? My 4S feels like it's slowly had enough, the battery is dying on me too. I was once one of those guys that just kept having to upgrade to latest iPhone but this stopped when I bought the 4S! I now feel I'd like to "upgrade" to the 5C- mainly as I'd like to enter the 4G world and the 5C is an inexpensive way of achieving this, at £319 Sim free. However, the biggest bug bear is the 8GB capacity which is terrible. I don't tend to take many pictures at all or have many apps either which is good news however I do like my music. The 5S is too big a jump on price- especially as it isn't even the latest phone. The 16GB 5S (which is still relatively poor for storage) is selling for £459 here- if I was inclined to spend that kind of money for an older model I definitely would spend the extra £60 or so to get the 6. But I'm not! the 5C would do- but it's that 8GB issue.... What would you do?
