BGR.com tested Apple's latest iPhone 5 against previous models to see which smartphone had the best speakers.
Results showed that the iPhone 5, tested against five other models, clocked in at 1003.dBA, two dBA more than the speakers on the iPhone 4S. In fact, as some of the models increased, the decibel meter increased. The 2G measured 91.0 dBA, 3G measured 95, 3Gs measured 97.6, the iPhone 4 measured 92.8, the 4S measured 97.9.
The article said it appears Apple improved on the iPhone 2G speaker with the iPhone 3G and iPhone 3GS, but when it released the new iPhone 4 design, the speaker was significantly quieter than the previous two devices.
The iPhone is not only the loudest, but the thinnest and lightest to date. The phone weighs 112 grams and is 7.6 millimeters thin.
The nano-SIM card is 44 percent smaller than a micro-SIM. Apple said they have also developed a unique cellular solution for iPhone 5. The conventional approach to building LTE into a world phone uses two chips - one for voice, one for data. On iPhone 5, both are on a single chip. The intelligent, reversible Lightning connector is 80 percent smaller than the 30-pin connector. The 8MP iSight camera has even more features - like panorama and dynamic low-light mode - yet it's 25 percent smaller. And the new A6 chip is up to 2x faster than the A5 chip but 22 percent smaller. Even with so much inside, iPhone 5 is 20 percent lighter and 18 percent thinner than iPhone 4S.
