Samsung Galaxy S 4G (T-Mobile) Review: excellent battery life

The Galaxy S 4G has the same 1GHz Hummingbird processor; same 5 megapixel camera with 720p HD video capture; same 4-inch Super AMOLED display; and the same Wi-Fi, Bluetooth, and GPS support. It is, however, running a slightly updated version of TouchWiz on Android 2.2.1 Froyo (as opposed to 2.1 Eclair). 

The display looks fantastic. Battery life was excellent, the battery easily lasted through an entire day (full 24 hours) of extensive use. Call quality was for the most part very good, with a few minor trouble spots here and there. And the Galaxy S 4G easily found and latched onto T-Mobile's HSPA+ network, though it dropped to 3G and even EDGE a handful of times. the Media Hub has a tedious login process.  T-Mobile streamed video looked pixelated while standalone video looked fine.  Test photos were sharp and clear.
