Both of these powerful smartphones have yet another arena in which they are extremely similar, and that is around the features. Starting off, both the Samsung Droid Charge and the LG Optimus 2X have access to the newly created 4G network of their respective carriers. Both 4G networks are impressive but in a speed test, the Droid Charge easily wins, as Verizon's 4G LTE network is extremely fast. However, on the bad side, Verizon's 4G LTE network is very spotty, the connection does seem to come and go, but that may vary by market. In contrast, T-Mobile 4G HSPA+ network, while slower, is more consistent with no real connection errors. It's a toss up between faster but more unreliable speeds as opposed to slower but reliable speeds.
The cameras on both the Droid Charge and Optimus 2X are similar as well. Both smartphones pack 8 megapixel cameras, both capable of recording in 1080p HD. They also both have 1.3 megapixel front facing cameras used for video chatting. It's amazing how similar both are when it comes to the cameras. It's definitely a draw as these two smartphones are both great for video chatting as well as taking high quality pictures and videos.
The slight edge that the Optimus 2X has is the dedicated GPU alongside the two free games it comes with. Both Need for Speed SHIFT and N.O.V.A. are fantastic games on the Optimus 2X. Output these games on a large HDTV through the HDMI out and the slightly smaller screen is no longer an issue. The Droid Charge unfortunately doesn't come with any exclusive games, just the exclusive Verizon bloatware. In addition, for this particular battle, the steady access to the 4G network was more useful than the sporadic access available through Verizon. Couple that with the exclusive and fun games and the LG Optimus 2X edges out with the win.
Winner - LG Optimus 2X
