Assuming you want to buy a smart phone without contract
There are two categories of buyers.
1. People who want to choose a phone in their limited budget.
Buyers of this category can't get the best players in the industry with the all the best features, but the best of those available in their budget range.
2. People who just don't care about budget and want to get the top-notch devices.
High budget phones are always high end, more over, comes with almost all the features. Here, the buyer must worry about which devices performs best.
Smart phone buyers must prioritize the features offered by the phone on the basis of their interests in descending order. What you use most of the time goes with the highest priority, followed by the next important thing that you really consider important for you. It varies from person to person.
Things to consider -
Operating System - What OS you want to use and why? How many apps does it have in its particular application store? How frequently the updates are released? Is your device manufacturer or Operator fast and good at pushing updates. This will be more of a user biased decision, rather some one suggesting you. You will find majority of the apps for both iOS and Android. Blackberry is out the race currently. Windows Phone has surged once microsoft has taken over, the windows phone 8.1 is similar to windows 8 in computers, if you are a hard core windows fan go for it.
CPU, RAM and GPU - These are very important factors to consider while buying a smart phone. Your phones total performance is based on these two factors.
Is it Single core, Dual-core or Quad-core? if so, what is the processor speed and what is the processor make? How many no of cores does the GPU have? whats the speed of the GPU? How much RAM does it offer. Is it 512 MB, 1 GB or 2 GB? 512 MB should be sufficient, but if you are going to play games and do a lot of graphics oriented stuff, try to get higher
For example you picked three phones with same no of cores, same processor speed and same RAM. How will you decide? Then go with the benchmark tests. Browse the web for the phone of your choice and go through the results. You will come to know which device performs the best.
The decision of whether to make and release the future versions of OS for your device or not is mainly based on these factors.
Any thing below 800 Mhz is a strict NO NO
Design and Build Quality, Ergonomics - For users who care most about design? build quality? Choices of color and ergonomics, this is an important factor.
Screen - What size is it? What sizes you are comfortable to handle? What type of screen does it offers? How good the screen quality is when compared to the other options available? How good the viewing angles are? Does it comes with a gorilla glass? etc.
Camera - Front and Rear? Resolution? Optics? Clarity? Noise Reduction? FPS? No of shots per second? Other features like Wide Sweep Panorama, Best shot, ability to capture HQ pics while recording a video etc have to be considered
Memory - How much of memory is exclusively allocated for installation of apps other than media? Is it 8/16/32/64 GB Model? Around 1 GB of on board memory, with a extendable memory solution (using Micro SD cards) should be enough. But go for 16GB/32GB if you want to store lot of music and videos on the go
Connectivity and Battery life - What connectivity options are available? 3G, 4G or 4G LTE? What data plans are offered for it? What is the capacity of the battery? For how long does it run on voice calls, while using 3g, 4g LTE, wifi, GPS, continuous video playback? continuous gaming? You can find the details in internet. Again, the choice depends up on what you use most.This is one of the more important ones. Most smartphone batteries are drained in 20-24 hrs, based on your usage (the amount of calls you make, and the time you spend browsing the net, replying to e-mails, and navigating using GPS). Try to get the battery over 1800 mAH
Other features include NFC, Wireless charging, availability of cases and accessories etc.
Last but not the least, check how big a hole will the phone put in your wallet. :)
