Well, the tests are and reviews ans stuff is moving on and one but there is real one which we have to tell you guys. The SPEAKERS, iPhone 4’s speaker was the same of the last iPhone’s but as Apple said, it’ all new from inside. iDB folk’s tested the sounds of the iPhone 4 and iPhone 4S which proved that the iPhone 4S speakers are much louder than the iPhone 4’s. The test shows the decibel difference in between both the iPhone 4 and iPhone 4S.
In video folks place both the iPhone’s one by one and test the speakers at high volume. Below is the video
The iPhone 4S’s voice is more 6 decibels than the iPhone 4’s, another reason to snap iPhone 4S.
