A smaller package

The Lumia 820 also has many of the features of the 920 - including the same 1.5GHz dual-core Snapdragon prcoessor, super sensitive touchscreen, wireless charging and the high quality display - but is a slightly more compact form. It features a 4.3inch screen, less built-in storage, and a somewhat smaller battery than the Lumia 920, meaning that you might be spending a bit more time sitting on your Fatboy Recharge Pillow.
