The massive ratings organization has assigned a rank to the leading smartphones and carriers.

J.D. Power and Associations has now released the tenth version of its annual customer satisfaction rankings, making technology news for gadgets manufacturers and providers, alike.

The company has reported that once again, Apple is holding the top smartphone spot for all U.S. carriers.

That said, when it comes to the carriers themselves, iPhone is still being seen as a better performer for some than it is for others. When it comes to the overall level of satisfaction as reported in this technology news, the highest satisfaction with smartphone devices is from customers of AT&T. In second place is Sprint, followed by T-Mobile, then Verizon Wireless.

The technology news also gave a specific type of applause for Apple and Samsung for achievement.

What it determined was that Samsung and Apple were the only two brands of cell phone that were capable of achieving scores in overall satisfaction that met or that were higher than the study average in each of the four different performance factors that were taken into consideration. This, according to the J.D. Power 2013 U.S. Wireless Smartphone Satisfaction Study.

The report indicated that the smartphone models that were among the best across each of the four wireless carriers in the Tier 1 level included: Apple iPhone 5; BlackBerry Z10; Nokia Lumia 920; and Samsung Galaxy Note II. This list was presented in alphabetical order and was not arranged in any type of preference or performance level according to the data from the study.

This can give the opportunity to view the direction that these brands and carriers may be taking in the future so that more informed choices can be made in the upcoming months and predictions can be made for the next few years.

Smartphone based purchases are representing a very large proportion of the overall figure.

The largest online marketplace in India, Snapdeal, has just released its mobile commerce data in that it has revealed that at the moment 30 percent of online purchases are originating from smartphones.

This trend has appeared to increase to a tremendous degree on the website, skyrocketing over last year’s figures.

When compared to the mobile commerce proportion of online purchases, last year, it looks as though the figure has grown by a tremendous 10 times. This is because at the same time last year, only 3 percent of the Snapdeal purchases were originating from smartphones.

The mobile commerce research was conducted by Snapdeal, itself, and provides insight into buying behaviors.

This mobile commerce study provided interesting and useful knowledge regarding the way that consumers behave, and the trends that are forming around them. The average number of visitors recorded by Snapdeal for its website was between 35 and 40 million per month. Among them, 12 million are from smartphones. From that 80 percent is organic, and 60 percent is new to the website. Among those shopping from their smartphones, 75 percent were COD, while the last quarter paid in advance.

This last data suggests that consumers may not be entirely comfortable making mobile commerce purchases online, and that they are taking precautions by paying on delivery instead of trying to pay in advance before they have received the product, in the vast majority of circumstances.

The majority of the mobile commerce visits to the sites originated from the cities of: Hyderabad, Bangalore, Kolkata, Chennai, Mumbai, and Delhi – listed in no particular order. The top selling categories over this channel on the Snapdeal website were clothing (both men’s and women’s), men’s footwear, flash drives, and memory cards.

This mobile commerce data, as a whole, suggests that the majority of smartphone users are shopping a great deal more over their devices and that this growth rate is an exceptionally rapid one considering the difference between the figures from last year and the statistics that have been recorded from this year.
