Apples iPhone 6 could arrive in 4.7-inch and 5.5-inch variations this year, but those clamoring for the latter may have to hold their breath a bit longer. According to Taiwans Commercial Times, the purported phablet-sized iPhone could be delayed a year due to battery production issues. As pointed out by Cnet, battery manufacturers are having a hard time crafting a battery that would fit within the thin frame Apple wants for its 5.5-incher.
