If you don’t already own the smartphone in question (for example, if you’re reviewing a range of phones for your blog), visit one of the smartphone carrier’s retail store and play around with the phone, or ask a friend who owns the device if you can use it for a day. Learn about the phone’s features, design, pros, cons, and the price.
Be sure to include any relevant hyperlinks to help customers find the information you’re referring to, perhaps even purchase locations.
Talk about what you like about the smartphone you’re reviewing, how easy it is to use, what features in particular are of worthy note.
Look at the advertising blurb accompanying the smartphone. Consider whether you think the smartphone in question lives up to the hype or whether there are aspects that you don’t agree with. It will be important to compare your experience with the advertised promises. Even summarizing the review with the best “pro” and the most annoying or disabling “con” can be a good overall summary for readers. For example, “Pros: This smartphone has a battery that outlasts any of its competitors in the same niche. Cons: Its price and the limited color range. "
Post your review on a blog, on a review site, or anywhere else relevant and be sure to respond to comments made to you. Sometimes developers will also respond if your review has struck a chord, so it pays to monitor your review actively for a good period of time.
