These definitions can help you choose a phone whose specs meet your needs,they can also come in handy when you're trying to separate the truth from the hype in the sales pitches you encounter in commercials or in stores.

Before jumping over software,there is one thing you should decide, that is Get the Right Screen Size

Smartphone screens keep getting bigger, but what’s the right size for you? At this point, we would avoid anything smaller than 4 inches. The new sweet spot for smartphones is quickly becoming the 4.5 to 5-inch range, which is where you’ll find such handsets as the Samsung Galaxy S4 and HTC One. You have to stretch your thumb a bit to reach all four corners of the screen, but these phones nicely balance portability with the extra size users crave for gaming, watching movies and even just typing on a larger keyboard.

Display:

Most smartphones and regular cell phones today use LCD (liquid crystal display) technology, which offers reasonably sharp graphics and is relatively inexpensive to produce.

There are two main types of LCD displays on phones. TFT (thin-film transistor) displays use thin-film transistor technology to improve image quality. Unfortunately, viewing angles and visibility in direct light are poor, and TFT displays are relatively power-hungry. As a result, they tend to appear on lower-end, regular cell phones (sometimes called "feature phones").

IPS-LCD (in-plane-switching LCD) displays, found on the Motorola Droid X (marketed as a “Retina Display”), offers improved viewing angles and lower battery consumption than TFT LCD displays. Relatively powerful phones often use them.

AMOLED (Active-matrix organic light-emitting diode) display technology is gaining popularity in high-end phones like the Google Nexus One and the HTC Droid Incredible. The displays are much easier to view in bright, natural sunlight than their LCD counterparts; however, some users have noted that AMOLED displays are prone to rendering oversaturated colors. Supposedly, AMOLED displays require less power and thus conserve a phone's battery life; but in real-life battery tests, they consume just as much energy as LCD displays.

Samsung’s Galaxy S was the first smartphone to showcase the company’s own Super AMOLED technology.

Processor:

The processor inside a smartphone acts as the device's brain, handling most or all of the device’s central processing functions on a single integrated circuit, or chip.

The number of cores in the central processing unit (CPU), coupled with CPU frequency (MHz/GHz), is often touted as the most important set of parameters in the specification of a mobile platform.

If you like gaming with your droid,the more number of cores gonna give you are better performance.

For example,For example, Broadcom’s new concept quad-core (2+2) architecture facilitates intelligent offload to both GPU and VPU (Vector Processing Unit) cores. Resultant power-savings enable performance up to 1080p high-definition video and support for up to 42-MP camera solutions.

So,while shopping an Android, take time to assess the tasks you want your smartphone to perform. If you expect to consume a lot of multimedia content, browse the Web frequently, or run complex apps for extended periods, you might be happier with a 1GHz chip inside your phone.

RAM:

As is true of computers, a phone's ability to run multiple applications simultaneously depends on the amount of RAM it contains. Vendors rarely advertise the amount of phone RAM a particular model has, so do some research before you buy. When it comes to RAM, you can never have too much.

In terms of memory, 2GB of RAM has become standard on higher-end phones, as has 16GB of storage.Heavy app users and multitaskers should aim for 512MB as their minimum RAM figure. :cool:

Battery:

What good is a high-powered smartphone that runs out of power by lunchtime? Based on the LAPTOP Battery Test, which involves continuous 4G Web surfing on 40 percent brightness, the average phone lasts 6:06. That’s good, but we’ve seen several handsets last 7.5 hours or longer. For example, the Motorola Droid RAZR Maxx HD, which has a massive 3,300 mAh battery, lasted 8 hours and 13 minutes on our test. The Galaxy Note II, which benefits from a 3,100 mAH battery, lasted a whopping 10 hours and 12 minutes.

Camera:

Is there much practical difference in image quality between a picture shot with an 8-megapixel camera and one taken with a 5-megapixel camera? The megapixel count reflects the size of the camera’s sensor--a small device inside the phone that converts an optical image into an electronic signal. The higher the pixel count, the higher the resolution of your photos. But you’ll probably view most of your photos on your phone’s display or on a PC, where the two resolutions are typically indistinguishable. If you plan on printing your photos, however, a higher megapixel count will make a difference.

The HTC One, for example, shoots only 4-MP images but captures 300 percent more light than competing phones, giving you brighter photos. Also, pay attention to special features. For instance, the Galaxy S4 can shoot using both the front and back camera at the same time.

4G and HSPA+ Service:

The major wireless carriers are currently upgrading their 3G networks to 3.5G (HSPA+) or 4G (LTE or WiMax). Whether a specific smartphone supports these new network technologies (and their faster speeds) should be stated in the device's specifications.

Noise Cancellation/Suppression

“Noise cancellation” in smartphones might be better termed “noise suppression.” The phrase refers to isolating the sound of the speaker's voice while suppressing background sounds; noise suppression depends on having the design of a phone’s voice microphone (or microphones) work in concert with sound-shaping technology in the phone’s chip set.Since people rarely use cell phones in quiet rooms, noise suppression technology is an important feature.

Removable Storage: MicroSD Cards

SD (Secure Digital) cards and their smaller MicroSD and MiniSD memory-card cousins are the types of removable storage commonly used in portable and wireless devices to store data such as video, music, and image files. The main difference between standard SD, MicroSD, and MiniSD cards is their size.

If you're planning to store a large quantity of large media files (such as video) you may want to choose the largest-capacity card that your device will accommodate. The capacities of the MicroSD cards used in most cell phones range from 2GB to 32GB.

The SD Association has established various speed classes for SD cards. These classes represent the minimum speeds required to write various types of data to the card. Following are the most common speeds, together with the types of content they support, according to the SD Association.

Class 2 : H.264 video recording, MPEG-4, MPEG-2 video recording

Class 4: MEPG-2 (HDTV) video recording, DSC consecutive shooting

Class 6: Megapixel DSC consecutive shooting, professional video camera

Class 10: Full HD video recording, HD still consecutive shooting

Gyroscope vs. Accelerometer

Most smartphones come standard with an accelerometer, but only a few also include a gyroscope. Accelerometers help keep track of the position your phone is in; if you turn it onto its side, the display switches from portrait orientation to landscape mode. Accelerometers are also used in certain applications. In driving game apps, for example, the accelerometer lets you steer your car by tilting your phone from side to side.

Gyroscopes permit more-accurate recognition of movement in a 3D space. If you move your phone away from or toward yourself, the gyroscope can detect that motion. The feature is chiefly useful for gamers, as it makes precise motion-based gaming controls possible. In the future, the gyroscope may play a central role in controlling new and different types of apps. But for now, nongamers are likely to be content without this piece of hardware.

Bluetooth and Wi-Fi

Both Bluetooth and Wi-Fi have become common features on smartphones in recent years.

Bluetooth is a wireless technology that enables you to transfer and receive data between two devices at relatively short range--similar to the way two-way radios work. You can use Bluetooth to transfer files between a phone and an accessory such as a headset, or between a phone and a PC--for example, to transfer photos between your phone and your laptop for editing and viewing.

Wi-Fi 802.11 comes in several different protocols (a/b/g/n), each with different speeds and a different range. Having Wi-Fi on your phone allows you to connect to your home wireless network and use it to surf the Web, download apps, send e-mail, and perform other tasks. Most Wi-Fi enabled phones will at least support b/g wireless broadcasts (54 mbps for g and 11 mbps for b) as these are the most common protocols and have decent range (around 125 feet).

Get the Best Special Features

In the new smartphone arms race, designers want to deliver special features that let you do things with your phone you couldn’t before. For example, the Samsung Galaxy S4, LG Optimus G Pro and HTC One can all be used as TV remotes, because they integrate an IR blaster and a dedicated app. Samsung goes the extra mile with the Galaxy S4, offering new Air Gestures, health and translation apps, and the ability to broadcast the same song to multiple S4s simultaneously.

HTC touts Beats Audio for both its Android and Windows phones.
