Up against each other in a battle of legalities, Apple and Samsung are also competing in the tech buyer's market as well.  

Apple's yet to be released iPhone 5 will soon have to compete with Samsung's Galaxy S3, which are both very similar in size and overall perks.

The iPhone 5 is rumored to be switching up its screen size to a 4-incher with a 1,136x640 IPS resolution.  However, the Galaxy S3 does have a bigger screen at 4.8-inches with an even higher resolution of 1,280x720 IPS.  Hence, the Galaxy S3 has the advantage in terms of screen size.

The iPhone 5 has been rumored to be running the upcoming iOS 6.  The respective version would increase SIRI functionality, raise the quality of social networking integration, and offer Passbook, which is a new payment system application.

In terms of battery life, the iPhone 5 is rumored to have improved itself immensely with a 1140 mAh battery while the Galaxy S3 possesses a 2100 mAh battery.  The iPhone 5 is expected to launch with 4G LTE.

If the new iPhone does not have the LTE mentioned then many are predicted to be upset, but the battery life should still be comparable to the S3.

The Samsung Galaxy S3 and the iPhone 5 are expected to be pretty similar in processing speed and RAM.  

However, Apple will be changing the pin connector for the iPhone 5, which is the adaptor allowing use of old iPhone or iPad accessories.  The Galaxy S3 uses the regular micro-USB format, which allows for a broad range of compatibility with non-Apple smartphone models.

If one prefers an Android over an iOS then customers will most likely choose the Galaxy S3; if not the iPhone 5.  

Overall, both respective models seem very closely matched so it should be interesting to see how the iPhone 5 pans out upon its official launch slated for Sept. 12th.
