The Apple iPhone 4 CDMA was released in 2011 and was one of the first smartphones to be available on the Verizon network in the United States. It was also the first iPhone to feature a new design with a stainless steel frame and glass front and back.
Design
The iPhone 4 CDMA was a significant departure from the design of previous iPhones. It was thinner and lighter than its predecessor, the iPhone 3GS, and had a more angular look. The stainless steel frame gave the phone a premium feel, but it also made it susceptible to signal loss when held in a certain way.
Display
The iPhone 4 CDMA had a 3.5-inch Retina display with a resolution of 960×640 pixels. This was a significant improvement over the display on the iPhone 3GS, and it made text, images, and videos look sharper and more vibrant.
Performance
The iPhone 4 CDMA was powered by the Apple A4 processor, which was a significant improvement over the A3 processor in the iPhone 3GS. This made the iPhone 4 CDMA faster and more responsive than its predecessor.
Camera
The iPhone 4 CDMA had a 5-megapixel rear camera with a built-in LED flash. This was a significant improvement over the 3-megapixel camera on the iPhone 3GS, and it allowed users to take sharper and more detailed photos and videos. The iPhone 4 CDMA also introduced the front-facing FaceTime camera, which allowed users to make video calls to other iPhone users.
Battery life
The iPhone 4 CDMA had a 1420mAh battery, which was the same capacity as the battery in the iPhone 3GS. This meant that battery life was similar on both devices, with users getting around 8 hours of talk time or 10 hours of video playback on a single charge.
Overall
The iPhone 4 CDMA was a significant improvement over its predecessor, the iPhone 3GS. It had a new design, a faster processor, a better camera, and a sharper display. However, it was also susceptible to signal loss when held in a certain way, and battery life was not much improved over the iPhone 3GS.
