Apple launched iPad 4 in the year 2012, when everybody was probably expecting them to launch iPad Mini. 6 months before that, iPad 3 was launched. So, a replacement in just a matter of 6 months was a little unexpected and a bit of a shock. Anyways, it might have been a little shocking, but it was surely an upgrade over the iPad 3. It was quite a bit faster than the last release, but the biggest change it had was the new Lightning connector. It was quite an outrage at that time because people were already having plenty of cables and docks for the previous 30 pin connector, and after the launch of iPad4, the 30 pin connector was discontinued and was replaced by the Lightning connector. iPad 4 is currently off the market, but you can still get the used ones. Let us have a look at it, and find out what else was new in iPad 4 –
The design of the iPad 4 was very similar to that of its predecessor. You can also say that it was a clone to iPad 3. However, it had a few changes. There is Retina Display, along with the lightning port. The bezels are large. They save the iPad’s display from scratches when it’s kept face down. The size and weight are same. iPad 4 measures 241.2 mm x 185.7 mm x 9.4 mm, and weighs 662 gm. The Home key is at the front and the power key is on the top. The volume rocker and the screen rotation lock key is on the right-hand side. The 3.5 mm headphone jack is on the top as well. The Retina display which was also seen on iPad 3 is here, which is an LED-backlit IPS LCD display with a resolution of 2048 x 1536 pixels and has a pixel density of 264 ppi. The screen size is 9.7 inches, and it is protected by the scratch resistant glass which has an oleophobic coating. The display offers quite sharp images and the pixels are very barely visible and that too while looking at it really close.
At the time of the launch, iPad 4 was equipped with the most powerful chipset Apple was having. The A6X processor is a dual core, clocked at 1.4 GHz. The GPU used is PowerVR SGX554MP4 (quad-core graphics). As usual, this iPad also comes in different models according to the capacity of internal space. All the four models with an internal memory of 16GB, 32GB, 64GB and 128GB, have the same 1GB of RAM. iPad 4 comes with iOS 6 operating system, but it is upgradable to iOS 10.1.
On the back, the Apple iPad 4 has a 5-megapixel iSight camera which is capable of producing images of 2592 x 1944 pixels and can record videos at 1080p at 30 fps. Also, the front facing 1.2-megapixel camera can record videos at 720p at 30 fps. The rear camera has phase detection, autofocus and the picture quality is pretty good, even under low lighting conditions. There is no LED flash on the back to support the primary camera. The camera app is filled with numerous features and scene modes. These scene modes can be used to tweak image quality, select suitable brightness and use stunning picture effects. It has several features like Geo -tagging, touch focus and face detection. There is no panorama and HDR. Overall, the camera app seems good and the picture quality turned to be good for a 5-megapixel camera. The amount of detail is also good. Although the camera overexposes some bright areas, but anyway, with such a big tablet, no one would be doing a lot of shooting.
The Apple has been solid in the department of battery for years, and same is the case with iPad 4. The battery used in this tablet is a non-removable Li-Po 11560 mAh battery (42.5 wh). With retina display onboard, along with so many high-end specs, the battery still gives a solid performance. The iPad 4 is available in two variants: iPad 4 WiFI and iPad 4 WiFi + Cellular (4G/3G). Remaining connectivity options are: Wi-Fi 802.11 a/b/g/n, dual-band, hotspot; Bluetooth v4.0, A2DP; GPS, with A-GPS, GLONASS and USB v2.0 (reversible connector).
