The performance improvements over the 3G were dramatic , and that may not be as apparent for iPhone 3GS owners. The 3G I had was slowing down significantly, and have installed iOS4 on it there was a noticeable degradation in responsiveness and battery life.
The iPhone 4 is noticeably heavier and slimmer than the older models, and looks slicker than the predecessor with its minimalist finish.
I did have an issue with dropping calls at the beginning, but this seemed to dissipate following the 4.1 software upgrade and also I added a slim protection case to the back of the phone. The case may have reduced the effects of the “death grip” problem where the antenna loses signal on contact with a conductive surface like your hand.
Apart from some teething problems with calls dropping at the beginning I have had very little trouble with the iPhone 4.
Here are the main benefits:
- Up to 2 full days battery life under normal conditions, and the battery meter is very reliable and accurate
- Performance is snappy and responsive and particularly running demanding 3D games is a joy
- The high resolution Retina display makes fonts look great and improves the general image sharpness greatly
- Photos are still great, just like on the 3G/3GS but with higher resolution images (1600 x 1200 >> 2592 x 1936)
- HD Video (720p) is excellent and hugely useful for all sorts of situations
- The screen surface seems very durable and I haven’t put a single scratch on mine yet
- The mute switch on the side now stays in position now and doesn’t accidentally flick to the wrong position
Some areas that could be improved
- I tried the “Facetime” service using the front camera over a Wi Fi connection but it suffered from latency badly
- The weight of the device is heavier than most other phones on the market, this is a minor drawback
- Battery life has improved but ideally can be increased in future versions to 4 or 5 days
I have used a number of other phones including Samsung and HTC on Android and they are catching up with the iPhone, but there’s still clear daylight between the Apple device and the others which is partially down to the hardware and build quality, but mostly because of the iOS software and the regulation of Apps to ensure quality standards.
Overall the iPhone 4 is the must have communications device of its generation.
