Saving Battery Life
Find out what's using juice:
SMS, MMS, iMessage
SMS - Short Message Service - Short, 160 character text messages.
MMS - Multimedia Messaging Service - Standard for multimedia, primarily for sending pictures taken on the phone. No formal size limit but 300 KB is the recommended max.
iMessage - Instant Messaging
SMS and MMS are transmitted as text messages over the phone network and will incur text charges if you don't have unlimited text.
iMessage goes over the Internet.
If you are concerned about your SMS/MMS usage and want to devote yourself wholly to sending iMessages, then fire up your iPhone, iPad, or iPod touch and open the Settings app. From there, tap Messages.

What you see straight on is cropped. Tilting your iPhone or iPad shifts the background right or left, up or down in order to create the effect that the device moves with you, iOS has to take into account that the background has to have some padding on every side in order to do so..
